“[T]hree particles move in space under their mutual gravitational attraction; given
their initial conditions, determine their subsequent motion.”1
Thus states the “three-body” problem. Its simplicity should not fool us: it
cannot be precisely solved. Under the same constraints, a two-body problem can be
solved precisely. That is, the subsequent motion of the two bodies can be mapped
and predicted with certainty. Add a third body and certainty disappears. “The orbits
[of the three bodies] can be calculated numerically for a while. . . But the equations
cannot be solved analytically, which means that long-term questions about a three-
body system cannot be answered.” Those questions are fundamental; they implicate2
the long-term stability of the solar system.
Perhaps we lawyers should not be discouraged, then, that we seem to make
so little progress on our own three-body problem: the function of and relationship
among the three institutions of the national government. Separation of powers is
deceptively simple: three entities with three distinct powers and the relationshipamong the entities. And it appears to implicate vital questions about the health and
stability of the governmental system. Still, we cannot seem to solve the problem of
separation of powers. We are not even close. We do not agree on what the principle
requires, what its objectives are, or how it does or could accomplish its objectives.

Lack of progress is not for lack of attention. Law libraries house shelf after shelf of academic commentary devoted to the analysis of separation of powers
questions. The debate is well-developed: it includes two competing schools of
thought, usually known as formalism and functionalism, and the predictable bickering
back and forth between adherents of each school. Nor is the debate confined to the
academy. The Supreme Court has decided an ever-growing set of cases implicating
separation of powers in the last twenty-five years. In its most recent outings the
Court rejected President Clinton’s claim to limited immunity from civil suit while in
office and invalidated the popular line-item veto. As those two cases and many3 4
others attest, the Court is not hesitant to rebuff the other branches of government to
heed its view of the dictates of separation of powers. But the Supreme Court’s case
law is no more settled than the commentary: it has been called an “incoherent
muddle,” produced by a Court that is “stumped” by separation of powers questions.5 6
This Article claims that we have made so little progress because we are
arguing about the wrong questions. The hotly contested debate over formalism and
functionalism is a distraction. A closer look at that debate reveals a surprise: despite
surface disagreement, courts and commentators embrace a remarkably consistent set
of ideas about separation of powers. That latent consensus is civics-class familiar.
It holds that separation of powers is a way to prevent a single institution of
government from accumulating excessive political power; the way to achieve that
objective is to disperse the three governmental powers--legislative, executive, and judicial--among different institutions and equip each department with select powers
to protect itself and police the other departments. Not only have we failed to notice
this robust consensus residing just under the surface of the conventional debate, but,
much more importantly, we have failed to critically examine it.
Having exposed the consensus, this Article then critically examines it. The

The Real Separation4
examination reveals the consensus to be underdeveloped, confused, and possiblyincoherent. The key problem is that the consensus simultaneously embraces two
distinct substantive conceptions of separation of powers that do not easily fit together.
One conception, called here separation-of-functions, stresses the need to keep the
three government powers in different departments; the other conception, called here
balance-of-powers, stresses the need to balance the departments of government
through the creation and maintenance of tension and competition among them.
Courts and commentators conflate the two conceptions or treat them as if they easily
relate to one another.
Muddling these two conceptions together, however, is a mistake. The
conceptions do not easily relate to one another. They are distinct, both historically
and conceptually. Attempts to connect the two prove fruitless and the conceptions
suggest different--often irreconcilable--doctrinal concerns. And as a result of the
muddling of the two ideas, neither of the conceptions has been independently
subjected to critical analysis. The separation-of-functions conception, for its part, is
poorly articulated and defended: the reasons why we might wish to separate
governmental functions are all but lost in discussions of separation of powers. The
balance-of-power conception is likewise underdeveloped: what is meant by balance
is obscure and the way in which that balance is maintained is unstated.
The lesson of this Article, then, is that the consensus must be abandoned infavor of a new set of ideas about separation of powers. The Article takes the first
step toward a new consensus. By seeing past the surface squabble between formalists
and functionalists to the surprising, but robust, consensus, and, then, critically
examining that consensus, this Article extracts the two distinct and sometimes
conflicting conceptions from the muddle of the present consensus. While the latter
steps of constructing a new consensus are not completed here, the challenges of those
steps are clarified by this effort.
The Article is organized as follows. Part I describes the case law on
separation of powers and reviews, briefly, the competing approaches to separation of
powers that appear in the literature. The lesson of this Part is that, conventionallydescribed, disputes over separation of powers controversies are organized around a
choice between “formalist” and “functionalist” approaches. In Part II, I show why
that conventional description is misleading. By stepping back from the surface split
between formalist and functionalist methodologies, I demonstrate that courts and

commentators actually agree on a theory of separation of powers. That theory isfamiliar, but it is now hidden in the contest between formalism and functionalism.
Having noticed this consensus, Part III then critically examines it. Examination
exposes the consensus as deeply confused and possibly incoherent. The key difficulty
is that the consensus simultaneously embraces two distinct substantive conceptions
of separation of powers. The different conceptions are muddled together in the
consensus, but they are not the same, nor are they particularly compatible. And
muddling them together has prevented critical examination of each conception on its
own terms. The lesson of Part III, then, is that the latent consensus must be
abandoned. Part IV concludes the Article and sketches the challenges ahead in the
effort to fashion a new consensus.
I. The Contested Terrain
A. The Terrain: Separation of Powers Defined and its Resurgence in theCourts
The set of principles comprising “separation of powers” are far more easily
invoked than defined. Separation of powers refers to a theory about the appropriate
allocation of government authority among the institutions of the national government.
It means, on the one hand, classification of governmental power into three categories,
allocation of that authority to three different institutions, with separation of personnelamong the institutions. Traces of this “pure” doctrine are evident in the Constitution:7
Articles I, II, and III refer to three different types of governmental power and allocate
those powers to three different institutions with separate personnel. At the same8
time, the Constitution contains celebrated departures from pure separation, usually
dubbed checks and balances: the Senate’s advise and consent functions, thought to
be executive in nature ; Congress’ involvement in the judicial function of 9

impeachment ; the President’s power to approve or veto legislation, involving him10
in the legislative function. Separation of powers, so described, is concerned with an11
almost limitless set of questions regarding the structure of and relationship among the
institutions of the national government: the character and structure of each institution
(elected or appointed), including in some cases the internal structure of the institutions
(division between the House and the Senate); the allocation of those institutions’
respective powers (legislative, executive, judicial); and the ways in which the
institutions interact with one another (veto and override power, Senate advise and
consent, impeachment).
When one switches from theories about the ideal structure of and relationship
among the institutions of the national government to the more limited set of questions
judges address as they struggle to interpret and apply the provisions of the
Constitution concerning separation of powers, the range of relevant questions remains
enormous. Consider the issues conventionally described as within the separation of
powers basket: the legitimacy of Article I courts, created by Congress and (usually)
located in administrative agencies; the non-delegation doctrine; Congressional (or
judicial) involvement in the appointment, or removal, of officials exercising functions
that are not obviously legislative or judicial in character, including the specific subset
of Appointments Clause questions raised by congressional limitations on the
President’s ability to remove officers; the legislative veto; the creation of hybrid
entities, like the U.S. Sentencing Commission, to develop and implement particularized guidelines or administer certain tasks; the President’s authority to
initiate policy; the President’s ability to “veto” aspects of legislation; the extent of the
President’s executive privilege and judicial immunity; and, the division of authority
between the President and Congress with respect to foreign policy and war powers.12
But even beyond this set of conventionally described separation of powers disputes,
there are others fairly characterized in the same way: for instance, the scope of the

Commerce Power ; the legitimacy of judicial review of legislative and executive13
acts ; the scope of Congress’ authority over the jurisdiction of the federal courts.14 15
Each of these controversies involves separation of powers in that each involves the
scope of power of one of the departments, or the way in which the national
departments of government interact with one another. The breadth of this list goes
a long way toward explaining why a commentator or court can, on almost any
question involving the exercise of federal power, invoke “separation of powers”
principles as relevant to the controversy.
However one describes the content of the field, we are in the midst of a
doctrinal revival of it. Until twenty-five years ago, there were a handful of cases that
did all the heavy lifting with respect to federal institutional arrangements. The famous
steel seizure case--Youngstown Sheet & Tube --remains the significant16
pronouncement by the Supreme Court regarding the scope of the executive power.
And the whole of the constitutional validity of the modern administrative state had,
before 1976, been thought to be resolved by, on the one hand, the quixotic
nondelegation doctrine--boldly emerging only to soon be all-but-officially retired --17
and, on the other, a handful of cases on a narrow question regarding the
Appointments Clause. Myers v. United States, decided in 1926, held that the
President’s power to remove an executive officer (in that case, a postmaster first

class) could not constitutionally be conditioned on the consent of the Senate.18
Though Myers suggested that the “independent” aspects of some administrative
agencies might violate the constitution, a mere nine years late in Humphrey’s
Executor v. United States, the Court sustained Congressional restrictions on the19
ability of the President to remove a Federal Trade Commissioner. There, the Court
declared that it was “plain under the Constitution that illimitable power of removal is
not possessed by the President in respect of officers of the character of those just
named.” Though the Court’s reasoning was unhelpful, Humphrey’s remains the20 21
prime support for the constitutional validity of independent agencies.22
Starting in the mid 1970s, the Supreme Court reentered this arena, and there
is no exit in sight. It is true that a surprising number of basic questions about
horizontal constitutional structure remain judicially unanswered, but the courts have
traversed much terrain in the last twenty-five years. In a run that includes the
invalidation of two veto provisions--the legislative veto in 1983 ( Immigration and
Naturalization Serv. v. Chadha ) and the so-called line-item veto in 1998 (Clinton23

of the Board of the National Credit Union Administration without cause in the interim between the

replacement); FEC v. NRA Political Victory Fund, 6 F.3d 821 (D.C.Cir. 1993), cert. dismissed , 115S.Ct. 537 (1994) (holding that Congress exceeded its legislative authority by placing congressional

B. The Terrain, Contested
Do not mistake the flood of cases for a developing consensus about resolving
questions of horizontal constitutional structure. There has long been a lively debate
about whether our separation of powers system is superior or inferior to a British-
style parliamentary system. And that debate has been recently renewed in the law38
review literature by Professor Ackerman, who provocatively attacks presidential

confines of the separation of powers system established by the Constitution, there is
nothing resembling agreement. As the testy opinions in the line-item veto case reveal,
the disagreement in the courts remains strong. And, as this Part will demonstrate, the
commentary is just as contested. Among commentators, there are two well-defined
and competing positions: formalism and functionalism. Commentators are usually40

preoccupied by the so-called “unitary executive” debate and that sub-field isdominated by Constitutional text parsing and dueling accounts of the original
understanding of the executive department. For its part, the Supreme Court42
vacillates between what is described as formalist and functionalist approaches, fully
embracing neither, and sometimes borrowing from both. Neither of the dominant43
approaches, then, provides a consistent account of the methodology applied or the
outcome of the cases.
At one level, formalism and functionalism are quite familiar: they track the
conventional choice between rules and standards. And, yet, in the context of this44
particular debate, the concepts travel with additional baggage beyond the choice
between a rule or a standard. Breaking the approaches down into their constituent
parts is hence useful; doing so allows us to focus more carefully on the points of
disagreement among the commentators.

at least in my hands, is the application of originalist textualism to questions of constitutional structure.”).
Some formalist commentators largely reject originalism, see Redish, supra note ___, at 6-10 (advocatinga textualist, not originalist, approach to questions of constitutional structure); see also id. at Chapter 4
(stating and defending a `pragmatic’ formalist approach to separation of powers).
Formalists who treat historical analysis as second in importance to textual analysis include
Calabresi & Prakash, supra note __, at 550-559; Miller, supra note __, at 57-58. Formalists drawing
extensively on both textual and historical analyses include Carter, supra note __, at 371 (arguing that the
“interpretive task is to meld text, structure, and history – including the deep and rich political science of
the Founding Generation – into a coherent whole, by immersion in the intellectual currents of the
Founding Generation”); see generally Liberman, supra note __; Currie, supra note __.
Deriving the rules from the text and original understanding is a conventional if controversial
move, controversy that would be familiar to any who passingly follow debates about constitutional
interpretation generally. In a nutshell, the pressing questions are these: Even if it were possible to arrive
at a determinate understanding of the text and the original understanding, which it may not be, why should
such sources control today? See, e.g., Flaherty, supra note __, at 1745-1755 (arguing that history isrelevant to separation of powers analysis and that deeper historical accounts are required); Redish, supra
note __, at 6-10, 126-128 (favoring text over history and rejecting Carter’s originalist separation of
powers analysis); Calabresi & Prakash, supra note __, at 550-558 (asserting primacy of the constitutional
text and defending standard originalist methodology); Lessig & Sunstein, supra note __, at 85-106
(arguing for ‘translation’ of founders’ values in a context of changed circumstances); Carter, supra note
__, at 364-371 (justification of originalism in terms of legitimacy and the understanding of the people).
For the formalist, questions of horizontal governmental structure are to beresolved by reference to a fixed set of rules and not by reference to some purpose of
those rules (making the affinity to rule-based approaches obvious). Beyond a bare45
commitment to resolving disputes through a determinate set of rules, the formalist
position further requires that the rules be derived from specific sources and, although
there are domestic squabbles, there is fairly wide agreement among formalists about
the content of the rules.
As to the source of the rules, they are to be derived from the text of the
Constitution and, for some but not all commentators, the original understanding of
that text. Examination of these sources yields a set of rules; it is in these rules that46
one comprehends the piercing doctrinal bite of the formalist position. As Gary
Lawson, a self-described formalist, explains:

Agencies, supra note ___.
Formalists treat the Constitution’s three “vesting” clauses as effecting acomplete division of otherwise unallocated federal governmental authority
among the constitutionally specified legislative, executive and judicial
institutions. Any exercise of governmental power, and any governmental
institution exercising that power, must either fit within one of the three formal
categories thus established or find explicit constitutional authorization for
such a deviation. The separation of powers principle is violated whenever the
categorization of the exercised power and the exercising institution do not
match and the Constitution does not specifically permit such a blending.47
Thus, the structural provisions of the constitution specify the type (legislative,
executive, judicial) and place (Congress, President, Supreme Court) of all
governmental power. The judge assessing the validity of an institutional arrangement
must first identify the type of power being exercised and, unless one of the explicitly
provided-for exceptions is relevant, make certain that that power is exercised by an
official residing in the appropriate governmental institution.
While all of the criticisms of formalist approaches will not be rehearsed here,48
two are worth mentioning because they highlight the differences between formalism
and functionalism. First, heeding the “identify-and-place” rules would, it should be
obvious, have dramatic practical consequences. Consider a dominant feature of 49
contemporary government: administrative (including so-called independent) agencies.Both of the garden variety forms of administrative action--rulemaking and
adjudication--present serious constitutional difficulties on the formalist account.
Rulemaking, the promulgation of prospective, general rules that bind private parties,
looks in many cases like the exercise of the power vested exclusively in Congress, that

Draft 15
Some formalist commentators acknowledge that, on a formalist approach, there should be50
serious constitutional questions about the exercise of what looks to be legislative power by administrative
agencies. See, e.g., Redish, supra note ___, at 136 (“While definitional questions will arise as to whether
action may properly be characterized purely as `legislative power’ rather than executive power, there can
be little doubt that judicial abandonment of the nondelegation doctrine has authorized breaches of the
definitional limitations.”); id., at 141-161; Lawson,The Rise and Rise,
supra note ___, at 1239-41.Yet the deep inconsistency with the formalist account of placing powers that appear to be
indistinguishable from legislative powers within administrative agencies seems to be a blind spot for
formalists otherwise committed to the cause. Many formalist commentators either ignore this apparent
inconsistency, defend the exercise of legislative power by administrative agencies, see Saikrishna
Bangalore Prakash, Deviant Executive Lawmaking , 67 GEO. WASH. L.R EV. 1, 11-16 and n. 96 (1998)
(delegation of “discretion” or “legislative” power unavoidable and permitted by the necessary and proper
power); see id., at 14 (“one may view delegated discretion as proper and necessary to the effectuation of
legislative powers.”), or heroically attempt to characterize the work of administrative agencies as merely
“interstitial policymaking” and hence legitimate executive activity, see Liberman, supra note ___, at 347,
n.209 (the supposed disjunction between the formalist approach and the realities of modern-day
government “go away once one accepts the proposition that execution of the laws includes interstitial
lawmaking. ... At that point, most activities of law administering officers are appropriately characterized
as executive.”) This defense of “legislative” activity of administrative agencies might make sense if onewants ever more expansive power for the executive branch, but seems quite difficult to square with the
rest of the formalist approach. For a criticism along similar lines, see Greene, supra note ___, at 157.
Lawson, The Rise and Rise, supra note ___, at 1237-1249 ; Calabresi & Rhodes, supra note51
___. On legislative courts, see Richard H. Fallon, Jr., Of Legislative Courts, Administrative Agencies,
and Article III , 101 HARV. L. R EV. 915 (1988); Martin H. Redish, Legislative Courts, Administrative
Agencies, and the Northern Pipeline Decision, 1984 DUKE L.J. 197; Henry P. Monaghan, Marbury and
the Administrative State, 83 COL. L. R EV. 1 (1983).
A formalist approach would also mean the end of the appointments arrangements governing so-
called independent agencies such as the Federal Trade Commission. Statutory independence for
commissioners (through, for example, limitations on the President’s ability to remove them) at the helm
of such agencies violates the tenets of the formalist rule book. Relying on the text of the Constitution--in
this case, the “vesting” and “take cause” clauses of Article II--and the original understanding, formalistsview the constitution as creating a “hierarchical, unified executive department under the direct control
of the President.” See Calabresi & Rhodes, supra note ___, at 1165. On this reading, the President must
have, at the very least, unfettered ability to appoint (with of course the advice and consent of the Senate)
and remove such officers, which renders restrictions on the President’s ability to remove officers
unconstitutional. See Currie, supra note ___, at 34-36; Redish, supra note ___, at 130-31; Miller, supra
note ___, at 44, 96-97.
is, legislative power. Likewise, adjudication of individualized disputes carried out50
in administrative agencies looks like a classic exercise of judicial power, a power
vested by the Constitution in the Supreme Court and such lower courts as Congress
creates.51

The Real Separation16
While proponents of the unitary executive believe generally that the President should have
control over his subordinates, opinions do vary as to how this control should manifest itself. Possibilities
range from the plenary removal power advocated by the scholars above to direct presidential influence
over administrative officials to declaring the actions of “insubordinate subordinates” legally void. See
Steven G. Calabresi, Some Normative Arguments for the Unitary Executive, 48 ARK . L. R EV. 23, 58
(1995); Liberman, supra note __, at 353-358; Lawson, The Rise and Rise, supra note __, at 1243-1245
(arguing that removal power in itself is either inadequate or superfluous and that the President should beable to control directly the actions of administrative officials or to void administrative actions contrary
to his policy goals).
Formalists, of course, do not view the transformative consequences as an indictment of their 52
approach. See Lawson, The Rise and Rise, supra note ___, at 1249 (stating a willingness to “hold fast
to the Constitution though the heavens may fall”); Liberman, supra note ___ 347, n. 209, 357-358 (“The
fact that a theory justifies the status quo is not much of a virtue. It would be better that the political
branches always devised institutions that complied with the Constitution.”) and id. (“The alternative view
that any theory treating established institutions as constitutionally suspect cannot be right turns out in [the
case of article I courts] to encourage the creation of more of them, ultimately to the detriment of
constitutional rights.”).
For an exploration of this question in more detail, see M. Elizabeth Magill, Rethinking 53
Separation of Powers (manuscript on file with author).
488 U.S. 361 (1989).54
478 U.S. 714 (1986).55
487 U.S. 654 (1988).56
But it is more than transformative consequences that plague the formalist position. There is an independent problem with the formalist project: the enterprise52
depends heavily upon workable distinctions among the three categories of
governmental power. For in order to “place” correctly, one must “identify”
correctly. When examining the validity of an institutional arrangement--for example,53
the Sentencing Commission, the role of the Comptroller General under the Gramm-54
Rudman-Hollings Act, or the Independent Counsel --a formalist would have to55 56
determine, first, what sort of power the entities or officers were exercising. While the
formalist approach thus presupposes an ability to distinguish among the three types
of government power, the differences among those three powers are--to understate
the point--elusive. James Madison famously admonished that “Experience has
instructed us that no skill in the science of government has yet been able to
discriminate and define, with sufficient certainty, its three great provinces, the

Legislative, Executive and Judiciary[.]” Nor are our learned contemporaries any57
more confident of their ability to define the differences among the three governmental
powers. As Gary Lawson, among others, admits, “[the problem of distinguishing58
the three functions of government has long been, and continues to be, one of the most
intractable puzzles in constitutional law.”59
The formalist position would, then, if consistently followed in the courts,
require dramatic alteration of contemporary institutional arrangements and prevent
experimentation along similar lines in the future. It is probably no accident, then, that
Supreme Court opinions that are characterized as the most formalist ( New York,60
Chadha, Bowsher ) are those in which the Court has invalidated the statutory61 62
arrangement under consideration.
2. Functionalism
Formalism’s competitor, functionalism, is likewise a series of postulates rather
than a single precept. While a formalist is committed to rule-based decision-making,
a functionalist (making obvious the analogy to a standard) would resolve structural
disputes “not in terms of fixed rules but rather in light of an evolving standard

Strauss, Place of Agencies, supra note ___, at 581.69
designed to advance the ultimate purposes of a system of separated powers.” The63
agreed upon `ultimate purpose’ is to achieve an appropriate balance of power among
the three spheres of government. As the Supreme Court observed in upholding the64
constitutionality of the Sentencing Commission, “Congress neither delegated
excessive legislative power nor upset the constitutionally mandated balance of powers
among the coordinate branches.”65
But functionalism, just like formalism, is more than allegiance to a method of
deciding individual cases. The leading academic exponent of functionalism, Professor
Peter L. Strauss, has developed a comprehensive approach that allegedly captures the
virtues of a system of separated powers without requiring a radical dismantling of
contemporary government. Those guidelines are gleaned from and constrained by66
the familiar formalist materials: the text, original understanding, and interpretation
of the relevant provisions of the Constitution. Functionalist commentators tend to67
read those sources differently than formalists. And functionalists, moreover, are68
constrained by a factor that does not constrain formalists: the “reality of existing
government.”69

For functionalists, the relevant sources happily suggest constraints that canaccommodate those governmental institutions--administrative agencies--that pose the
most serious challenge to a commitment to separation of powers. Professor Strauss70
achieves that accommodation with a disarmingly simple observation: the Constitution
speaks only about the three named actors at the apex of government--Congress,
President, and Supreme Court. As to those three named constitutional actors,71
Strauss sounds just like a formalist reciting the identify-and-place rules: “as among
them, only Congress may legislate, only the Supreme Court may adjudicate, and only
the President may see to the faithful execution of the laws; and each is to have
significant function in these respects.” As for the subordinate parts of government--72
specifically, administrative agencies---no such rules apply. No such “core function”
analysis is required by the Constitution for the subordinate parts of government--for,
as Strauss points out, “below [the apex of government] the text does not speak.”73
The identify-and-place strategy is not necessary to achieve the benefits of separation
of powers. “So long as separation of powers is maintained at the very apex of
government, a checks-and-balances inquiry into the relationship of the three named
bodies to the agencies and each other seems capable in itself of . . . . preserving the
framers’ vision of a government powerful enough to be efficient, yet sufficiently
distracted by internal competition to avoid the threat of tyranny.” Strauss would74
thus abandon the formalist effort to place administrative agencies in one branch or
another, and likewise avoid the formalist requirement that the functions administrative
agencies’ perform correspond to the function assigned to the branch in which they arelocated; instead, he would direct focus to the relationship between administrative
agencies and all three of the actors at the apex of government. Those relationships75

accountability, without defending that choice, and for mistaking the “objectives sought to be accomplished

differences among the three powers of government. See M. Elizabeth Magill, Rethinking Separation of

must be such that the tension between the executive and legislative departments of government will be maintained.76
While the literature contains numerous critiques of functionalist approaches,77
one will be emphasized here. That critique focuses on the difficult-to-apply
methodology required by functionalism. Consider, for instance, some of the
functionalist standards that courts are to apply: Congress must “observe a principal
of parity in its treatment of the possibility of political control of agency action by itself
and by the President” and the President’s powers over administration and78
Congress’s powers must be “sufficient to give some assurance of maintaining a
continuing tension over ultimate political authority between [the President] and
Congress.” These inquiries, of course, assume that balance, and its specific79
applications, are the right standards. But the objection goes beyond that: formalists
argue that, even if we subscribed to the goal of balance, it would be impossible to
determine whether a particular arrangement would create an imbalance. Given that
balance among the departments would be unlikely to be upset at an identifiable
moment in time, as the result of a single arrangement, the functionalist approach calls
for a prediction that cannot accurately be made. When a new arrangement is80
initiated and challenged (consider the U.S. Sentencing Commission), how could the
Court predict what effect the arrangement would have over time? This familiar
criticism of the use of standards instead of rules may have particular bite in this

context given that the leading functionalist commentator appears to agree. If the81
standard cannot be applied effectively, the fear is that the immediate felt need for the
challenged arrangement would overwhelm the relatively abstract benefits of adherence
to a set of structural demands--even though, in the long run, adherence to the
structural demands is the better course. As if to reaffirm that fear about the nature82
of a functionalist inquiry, opinions characterized as functionalist (most famously,
Morrison v. Olson) have sustained the challenged arrangement, and the primary
judicial proponent of the functionalist approach (Justice White) would have sustained
challenged arrangements in every case he considered.83
3. Those Seeking Compromise
A conventional assessment of the cases and commentary would end right here.
But that catalogue ignores those relatively few commentators who seek ways other
than formalism or functionalism to analyze separation of powers questions. One
strand of brave soul has a simple solution: abstention. That is, have the courts refrain
altogether from deciding questions of horizontal political structure, particularly in
those cases where the Congress and the President agree on the outcome, a pattern
typical of recent controversies (line-item veto; sentencing commission, independent
counsel law).84
Most commentators, along with the Supreme Court, reject abstention. The
more typical route among the small band of commentators is compromise: splitting
the difference between formalism and functionalism, allegedly capturing the strengths

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 22/81
The Real Separation22
The most thoughtful of these approaches is the one developed by Professor Tom Merrill. See85
Merrill, supra note ___. In Merrill’s “minimal” approach, the “substantive interpretation of the
constitutional principle of separation of powers would reduce to a single, simple rule: Congress may not
create a Fourth Branch of the federal government.” Id. at 236. In this approach, every federal office
would be “in” one of the branches of government and subject to the constraints on action that apply to that
branch: Congress must act pursuant to bicameralism and presentment; the executive must act pursuant
to statute or an enumerated constitutional power; and courts must act through the adjudication of cases
or controversies. Id. at 239-241. Merrill’s approach would be a vast improvement over existing law,
but, on close analysis, it suffers from some serious difficulties. See M. Elizabeth Magill, Rethinking
Separation of Powers (manuscript on file with author).
Aside from Merrill’s approach, there are a variety of other commentators who attempt to bridge
the formalist-functionalist divide. See, e.g., H. Jefferson Powell & Jed Rubenfeld, Laying it on the Line:
A Dialogue on Line Item Vetoes and Separation of Powers, 47 DUKE L.J. 1171, 1196-1209 (1998)(suggesting formalist approach when actions by Congress are in question and functionalist approach when
actions by executive or judicial actors are at issue); Werhnan, supra note ___ (suggesting a formalist
`separation norm’ that, when violated, triggers a second step, modeled on intermediate scrutiny in equal
protection doctrine; second step to provide a `functional escape valve’); McCutchen, supra note ___
(suggesting that Court accept structures--such as administrative agencies--that have become
institutionalized even though those structures would have been unconstitutional in the first instance and,
to compensate, sustain practices--such as the legislative veto--that mitigate the effect of the acceptance
of the institutionalized structure).
See Brown, supra note ___ (arguing that the courts should explicitly consider of the potential86
effect of institutional arrangements on individual due process interests).
See Fitzgerald, supra note ___ (suggesting an approach based on the “nested constituencies”
87
created by the constitutional structure and the way in which that structure “maximizes the potential for
debate and disagreement within and among” various political constituencies); Victoria Nourse, Toward
a `Due Foundation’ for the Separation of Powers: The Federalist Papers as Political Narrative , 74
TEXAS L. R EV. 447 (1996) (emphasizing an understanding separation of powers that stresses political
allegiances to different departments of government, as opposed to one that focuses on the need to separate
governmental functions).
while avoiding the weaknesses of each. Others articulate alternative conceptions85
of separation of powers: one commentator would have courts explicitly consider
individual due process interests in separation of powers cases, and others emphasize86
the political and institutional differences among the departments of government, rather
than the differences in the types of powers exercised by those departments.87
For purposes of this Article, the important point about these commentators
is that none of them have transformed the formalist-functionalist debate. In fact, in
most of the attempts to find a third way, one detects the strong pull of formalism or

functionalism, which simply reaffirms the salience of that divide.
C. The Contested Terrain Reviewed
There are, then, a variety of approaches to separation of powers and, so far,
none have captured the commentators or the courts. There is one lesson, however,
that seems clear from this examination of the competing approaches: the disagreement
among courts and commentators about how to resolve separation of powers cases
runs deep. As this Part has described, there are many differences that divide the
dominant schools. Formalists want judges to rely on a rule; functionalists want judges
to rely on a standard. Formalists want those rules to be derived from text and/or
original understanding; functionalists consider those sources, but they also want to
preserve, if they can, settled institutional practices. Finally, formalists would be likely,
applying the rules they derive from their sources, to dismantle much of contemporary
government; functionalists, applying the standards they derive from their sources,
would not. This many-layered disagreement seems about as profound as
disagreement can be.
II. From Contested Terrain to Consensus
Casting the debate as a choice among formalism, functionalism, and splitting
the difference between those two is importantly misleading. That depiction conceals
the shared suppositions of nearly all of the participants. Stepping back from the
divide as it appears in the literature reveals a surprise: courts and commentators
embrace a remarkably consistent theory of separation of powers. As the next Part of
this Article will argue, obscuring this consensus is not only misleading, it is
misconceived because that focus has prevented us from critically examining the
consensus. First, however, this Part identifies the components of that consensus and
demonstrates the agreement about it.
Courts and commentators, formalists and functionalists alike, subscribe to a
consensus about the objective of the system of separation of powers and, also, about
the mechanisms by which that objective is to be achieved. First, courts and
commentators agree on the following objective: the system of separation of powers
8/12/2019 The Real Separation in Separation of Powers Law (SSRN)
http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 24/81
The Real Separation24
This objective is an intermediate, not ultimate, objective. That is, adherents of the consensus88
seek to prevent concentration of power in a single institution in order to achieve higher-order objectives.
Those higher-order objectives are nearly always stated in lofty terms--avoiding tyranny, protecting
liberty, and promoting the rule of law. Likes motherhood and apple pie, it is difficult to take issue with
them. But they do no work in resolving individual cases.
Nor is avoiding the concentration of political power in a single sphere of government the only
objective upon which courts and commentators agree. But it is the only overarching, meta-objective that
participants in the debate universally ascribe to the system of separation of powers. There are subordinate
objectives, ones that relate to particular allocations of authority. For instance, vesting legislative power
in the Congress is designed to “give some substantial role in lawmaking to a body directly elected by the people,” Currie, supra note ___, at 22, while the vesting of judicial power in Article III courts was
designed to “guarantee their independence,” id. at 37.
The most contested of the sub-objectives are those associated with the view that Article II
establishes a so-called unitary executive. Those who subscribe to that construction of Article II
emphasize reasons why the executive authority was vested in a single, elected, head of government: to
promote the objectives of energy and accountability. See Calabresi & Rhodes, supra note ___; Calabresi
Some Normative Arguments, supra note ___, at 37-47 (cataloguing reasons for unitary executive: energy,
accountability, and enabling the President to defend himself from an encroaching Congress). Some
unitary executive theorists argue that the meta-objective (avoiding undue concentration of power) is
consonant with, see id., or should not be emphasized over, the objectives of energy and accountability,
see Liberman, supra note ___, at 345 (criticizing functionalist approaches for elevating “checks-and-
balances” objective above other objectives, such as accountability). Most critics of the unitary executive
do not contest the objectives of energy and accountability; rather, they object to the relative weight thatshould be put on these objectives. See Flaherty, supra note ___, at 1740-42.
Intriguing critiques of the unitary executive view are contained in Cynthia Farina, The Consent
of the Governed: Against Simple Rules for a Complex World, 72 CHICAGO-K ENT L. R. 987 (1997)
(efforts to legitimate government through strong President will be ultimately unsuccessful); Michael A.
Fitts, The Paradox of Power in the Modern State: Why a Unitary, Centralized Presidency May not

is intended to prevent a single governmental institution from possessing and exercisingtoo much power. Second, courts and commentators also basically, though not88
universally, agree on the mechanisms by which that objective is to be achieved. There
are two components to those means. Commentators agree that governmental
functions (legislative, executive, judicial) are to be dispersed among different
governmental institutions. They also agree that, through the familiar features such as
the President’s limited veto, impeachment, and advice and consent, the institutions are
given the means to protect the exercise of their own functions and check the exercise
of functions by the others. This system will facilitate competitive tension among the
branches which, in theory, yields an equilibrium among them, preventing one from

This Part focuses on the agreement about the consensus among formalists and functionalists.89
It should be observed that those seeking a way out of that divide also embrace the consensus. See, e.g.,
Merrill, supra note __, at 255; see also id., at 252 (“The minimal conception would create a dynamic
tension between Congress and the other branches of government that would serve the central end of a
system of separation of powers – the diffusion of power to ‘protect the liberty and security of the
governed.”); Powell & Rubenfeld, supra note __, at 1204-1209 (describing their separation of powersapproach as an “anti-unilateral-power, checks and balances approach”); McCutchen, supra note __, at
21 (Arguing that the constitutional theory of the second best reinvigorates checks and balances and
restores the proper allocation of government power: “The constitutional theory of the second best seeks

and by strengthening institutions weakened by a prior error.”); Choper, supra note __, at 274-275 (“The
crucial issue is realistically to ascertain whether the institutionalized checks and balances that the framers
indisputably devised to fortify the separation of powers – thus excluding judicial review – are themselves

becoming dominant.89
Agreement on the consensus position--that is, the principal objective and the
means to achieve it identified here--can be found in both the courts and the
commentary. For court opinions and commentators characterized as functionalist, the
consensus on these points is obvious. The Supreme Court has noted that the
objective of the doctrine of separation of powers is to avoid the “greatest tyranny,”
namely, the “accumulation of excessive authority in a single branch.” As for the90
means, the Court has observed on numerous occasions that the “the system of
separated powers and checks and balances” acts as a “self-executing safeguard against
the encroachment or aggrandizement of one branch at the expense of another.”91
The consensus about ends and means is also evident in the work of
functionalist commentators, including the most influential of that group, Professor
Peter Strauss, although with an important twist. Recall that Strauss’s approach works

Strauss, Place of Agencies, supra note ___, at 602 (“[The purpose [of the government92
structure of separated powers and interlocking responsibilities] was to prevent both majoritarian rashness
and the governmental tyranny that could result from the conjoining of power in a single source.
Maintaining conditions that would sustain the resulting tension between the executive and the legislature
was to be the central constraint on any proposed structure for government.”); see also id., at 580 (“What
we have, then, are three named repositories of authorizing power and control . . . The three must share
the reins of control; means must be found of assuring that no one of them becomes dominant.”), id. at 581
(Describes his approach as a “framework for understanding the scope of Congress’s authority to structure
government that stresses the continuance of opposed, politically powerful actors at the apex of
government by requiring that those who do the work of law-administration have significant relationships
with each.”), id. at 597 (“The important constraint on Congress’s ability to structure the work of law-
administration lies in the need to perpetuate the tensions and interactions among the three named heads
of the Constitution. Whatever arrangements are made, one must remain able to characterize the Presidentas the unitary, politically accountable head of all law administration, sufficiently potent in his own
relationships with those who actually perform it to serve as an effective counter to a feared Congress.”),

on two levels: one set of rules for the named constitutional actors at the apex of government (President, Congress, Supreme Court) and one set of rules for the
subordinate parts of government. At both levels, Strauss agrees on the consensus
objective: preventing excessive accumulation of power in one sphere of government.
He argues that the way to achieve that objective is through the creation and
maintenance of competitive tension among the relevant entities. But for Strauss,92
creating and maintaining that tension is accomplished through different mechanisms
depending on the level at which he is working. At the level of the named
constitutional actors, Strauss would rely on what I have identified as the consensus
mechanism: a functional dispersal of governmental powers (in Strauss’s vocabulary,
core functions) and the various checks that the actors have on one another. At the93
subordinate level of government, Strauss agrees that the objective is to prevent one
department from becoming dominant over others. But functional dispersal of power
is not, according to Strauss, necessary to achieve that balance. The crucial doctrinal
consequence of that move, of course, is to render administrative agencies
constitutional, even though they appear to combine all three governmental functions
in a single institution. Instead of functional power dispersal, Strauss relies on a series
of rules and guidelines that are designed to create a certain type of relationship among
agencies on the one hand and the Congress and the President on the other. The rules

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 27/81
Draft 27
The rules are these: the President must appoint the head of the agency; the “agency in doing94
the work must have a relationship with the president consonant with his obligation to see to the faithful
execution of the laws” and the President must be able to demand written reports from the agency prior
to agency action. Strauss, Place of Agencies, supra note ___, at 640-41. The guidelines are these: the
President supervises the work of administrative agencies in light of the “elementary judgment that we
have a unitary, politically responsible head of government, possessed of sufficient independent authority
to serve as an enduring counterweight to the political muscle of Congress.” Id., at 641; see also id. at
667. In recognition of this role, Congress must observe a “principle of parity in its treatment of the
possibility of political control of agency action by itself and by the President” but the President “may be
able to claim relationships beyond the constraint of parity.” Id., at 641.
Strauss, Place of Agencies, supra note ____, at 643; see id., at 641, 667.95
Id. at 641.96
The most explicit references to the consensus ends and means appear in the following97
formalist opinions: Metropolitan Washington Airports Authority v. Citizens for the Abatement of Aircraft
Noise, 501 U.S. 252, 271-73 (1991); Bowsher v. Synar, 478 U.S. 714, 721-22 (1986) (“[the declared
purpose of separating and dividing the powers of government, of course, was to `diffus[e] power the
better to secure liberty’”) (citation omitted); Buckley v. Valeo, 424 U.S. 1, 122-23 (1975).
References to the consensus position are more difficult to identify in two formalist opinions, INS
v. Chadha and Clinton v. New York. The majority opinion in Chadha, 462 U.S. 919, does little more
than re-state the formalist rules: “The Constitution sought to divide the delegated power of the newFederal Government into three defined categories, Legislative, Executive, and Judicial, to assure, as
nearly as possible, that each branch of government would confine itself to its assigned responsibility.”
Id. at 951. Yet the majority opinion does refer to vindicating “the purposes underlying the Presentment
Clauses . . . and the bicameral requirement,” id. at 946. As identified by the Court, those purposes were
to permit the President to check the exercise of authority by Congress (presentment) and to assure
legislation was enacted only after much deliberation (bicameralism), see id. at 946-51. Justice Powell’s
are many and the guidelines rather complex. They are intended to structure the94
relationship among these actors in order to achieve the consensus objective by
“preserving the tension among the named branches”, so that “no one branch95
becomes dominant.”96
Formalists, too, subscribe to the consensus. Opinions characterized as
formalist, as well as most formalist commentators, take as a given that there are
underlying justifications to the rules that they identify, justifications that accord with
the consensus view. In the Supreme Court opinions characterized as formalist, the
Court refers repeatedly to both the consensus objective (avoid undue accumulation
of power in one sphere of government) and the consensus means (functional dispersal
of power and selected checks).97

principle of separation of powers was “designed to reduce the obvious dangers that
flow from the concentration of political power;” that is, separated powers is a98
strategy to “reduc[e] the likelihood of undue concentration of political power.”99
Formalist commentators likewise agree that the mechanisms to prevent concentration
of political power are the dispersal of governmental functions among different
departments and providing the respective branches with “the formal tools necessary
to limit the excesses of its rivals.” One set of formalist commentators concisely100
captured the entirety of the consensus position: “By simultaneously dividing power
among the three branches and institutionalizing the methods that allow each branch
to check the others, the Constitution reduces the likelihood that one faction or interest
group that has managed to obtain control of one branch will be able to implement its
political agenda in contravention of the wishes of the people.”101

separation of powers--separation of functions into three different departments--and checks and balances).
See also Jack N. Rakove, ORIGINAL MEANINGS: POLITICS AND IDEAS IN THE MAKING OF THE
CONSTITUTION, Chapter 6 (1996). One government textbook’s definition of separation of powers and
checks and balances accord with this statement of the consensus position, see James Q. Wilson and John
J. DiIulio, Jr., AMERICAN GOVERNMENT: I NSTITUTIONS AND POLICIES 33-35 (7th ed., 1998)
On closer inspection, then, the debate over the proper approach to separation
of powers is less contested than first imagined. Our excursion into functionalism and
formalism in Part I did reveal deep disagreement, but the close inspection in this part
uncovered a consensus about the ends and means of separation of powers that is
embraced by nearly all participants in that debate.
III. The Conflicted Consensus
Perhaps it should come as no surprise that beneath the surface split lie deeply
shared ideas about separation of powers. Mixed government, one of the intellectual
precursors of separation of powers, has an ancient pedigree and, as every diligent
civics student knows, power dispersal and selected checks are animating principles of
the Constitution’s design. But a standard depiction of the field paints deep102
disagreement between formalists and functionalists. The consensus is not
acknowledged as the consensus it appears to be.
It may be that status as shared articles of faith that explains why the
propositions comprising the consensus are never carefully analyzed. Rather, the
consensus operates like an anthem, sung as the enterprise commences, duly
dampening the eyes of all involved as they nod their heads in approval. That anthem
includes obligatory references to Madison and Montesquieu’s warnings thatseparation of powers is crucial to the prevention of “tyranny” and the protection of
our “liberty,” and paeans to our enviable system of fragmented power and institutional
competition. But the effort is superficial; the authors do not even clearly identify the
components of the system that are the subject of such celebration, much less provide
a precise explanation of the mechanism by which that system prevents tyranny and

The Real Separation30
Even with respect to the constitutional status of administrative agencies, the story is not that103
simple. Functionalist commentators would not accept an institutional innovation involving administrative
agencies if that innovation threatened the “core” function of the branch at issue. See Strauss, Formal and
Functional Approaches, supra note ___, at 489. That requirement to protect the “core” functions isrooted in a separation-of-functions conception, even though functionalists’ overall rule with respect to
administrative agencies--relaxing the command of functional separation while still preserving tension and
competition--is emblematic of the balance-of-power conception. And, with respect to separation of
powers questions that do not relate directly to the constitutional status of administrative agencies--issues
such as the independent counsel, the line-item and legislative veto, the scope and extent of executive
privilege--functionalist and formalist commentators adhere, simultaneously, to the two conceptions.
protects liberty.
This Part subjects the consensus to close analysis. Doing so exposes it as
deeply confused and possibly incoherent. The key difficulty is that the consensus
simultaneously embraces two distinct substantive understandings of separation of
powers. One understanding can be called separation-of-functions; the other can be
called balance-of-powers. The conceptions are distinct, both historically and today.
Despite this, courts and commentators muddle the two together, treating them as if
they are the same, or, as if they easily relate to one another. But it is difficult, even
tortured, to make the two conceptions compatible with one another, abstractly or
doctrinally. And the muddling of the two has prevented critical analysis of each on
its own terms.
It is important to observe at the outset that formalist and functionalist
commentators simultaneously adhere to these two conceptions, albeit with a
difference in emphasis. That is to say, it is not that formalists adhere to one
conception while functionalists adhere to the other. With respect to certain separation
of powers questions--such as the constitutional status of administrative agencies--
formalists emphasize one conception (separation-of-functions) and functionalists
emphasize the other (balance-of-power). But, if one takes seriously the way in103
which commentators describe their own views on separation of powers, formalists and
functionalists are committed to both conceptions of the consensus.
A. Two Distinct Conceptions within the Consensus: Separating Power andBalancing Power

accumulation of power within a single institution of government; the means to achieve

This is not a new difficulty. See Vile, supra note ___, at 13 (“An initial problem in any105

attaches to the word `power’ in the literature. It has been used to mean the possession of the ability

1. Two Conceptions: Separating Power and Balancing Power
What do those who endorse the consensus position mean when they write that
one sphere of government must be prevented from “accumulating too much power”?
The crucial term here is ‘power’ and it is a term with multiple meanings.104
Participants in the debate are rarely clear about what they mean when they use the
word. Case law and commentary actually reveal strains of two different105
understandings of the word power. The first meaning refers to the ability to act, or,
“ability to do or effect something or anything, or to act upon a person or a thing.” 106
This meaning of power has a familiar legal manifestation: “authority, capacity, or
right,” “authority or right to do or forbear derived by one person from another”; for
instance, the “ power to contract.” A second meaning of power, however, is107
broader and more colloquial: “The possession of sway or controlling influence over
others; control; authority; command; government; influence; ascendancy; ascendancy,
whether personal, social, or political.” Each meaning is associated with a distinct108
substantive conception of separation of powers.

The Real Separation32
THE FEDERALIST NO. 47, at 269 (Rossiter ed. 1999).
109
See TAN ___-___ (Part III.C.2.)110
There is another reason for separating functions that, as I argue later, see infra TAN __-___ 111
(Part III.C.2) is not operative today. That reason is efficiency; the idea is that separating functions permits
each department to specialize in and master the task assigned to it.
On one understanding, power refers to the ability to act, that is, the functionsassigned by the Constitution to different departments of government. Call this the
separation-of-functions understanding. Power refers to the three governmental
functions (or, powers) identified in the Constitution: legislative, executive, and judicial
powers (or, functions). The reference, then, to “undue” or “excessive” power is a
reference to a single government entity exercising functions in addition to those
identified in the Constitution as assigned to its department. There would be undue or
excessive power in one realm of government when, for instance, the executive
department exercises both executive power and legislative power.
The exact reasons for a prohibition on the accumulation of government
functions is surprisingly difficult to pin down. Other than declaring that the
accumulation of functions is the “very essence of tyranny,” courts and109
commentators rarely specify why governmental functions must be parceled out to
separate institutions. While this issue will be explored soon, a preview of the110
reasons provided for separating functions is useful. The justifications for separating
functions can be reduced to three : avoiding a concentration of political power in111
one sphere of government; “checking” the exercise of governmental power by each
institution; and, promoting the “rule of law”by prohibiting the same institution from
making the law and enforcing the law.
The separation-of-functions understanding is familiar and fits comfortably withsome of the explanations provided by adherents of the consensus position. The oft-
repeated Madisonian admonition from THE FEDERALIST NO. 47 makes reference to
this separation-of-functions conception: “The accumulation of all powers legislative,
executive and judiciary in the same hands . . . may justly be pronounced the very

complicated in this respect. Professor Strauss subscribes to the separation-of-
functions conception for the apex of government; he would rely on separation of
functions with respect to the President, the Supreme Court, and the Congress. But,
for Strauss, strict adherence to separation-of-functions is not necessary for the
subordinate parts of government.116

The Real Separation34
The original understanding of the role of judicial review is a question that has occupied many117
historians and I do not aspire to contribute to that debate here. For a sampling, see e.g., Dean Alfange,Jr., Marbury v. Madison and Original Understandings of Judicial Review: In Defense of Traditional
Wisdom, 1993 SUP. CT. R EV. 329; Sylvia Snowiss, JUDICIAL R EVIEW AND THE LAW OF THE CONSTITUTION
(1990); Robert Lowry Clinton, M ARBURY V . M ADISON AND JUDICIAL R EVIEW (1989); see also John
Harrison, The Constitutional Origins and Implications of Judicial Review, 84 VA. L.R EV. 333, 336-68
(1998). Based on that literature, it does seem fair to say this: the founding generation did not think of
judicial review as a robust check--akin to the President’s limited veto power, the Senate’s confirmation
power, or the Congress’ impeachment powers--on the exercise of authority by the legislative and
executive departments of government. When the founding generation referred to the ability of one
department to resist the excesses of another department, the devices that were being referred to were the
Presidential veto, the Senate’s confirmation powers, or Congress’ impeachment powers. This historical
record aside, it also seems fair to say that, today, many observers view judicial review as among the
critical “checks”--akin to the Presidential veto--on the exercise of governmental power by the political
departments. See, e.g., Michael J. Klarman, What’s so Great About Constitutionalism, 93 Nw. U. L.Rev.145, 155 (1998); Steven G. Calabresi, Textualism and the Countermajoritarian Difficulty, 66 GEO. W.
L.R EV. 1373, 1375 (1998); Nixon v. Fitzgerald, 457 U.S. 731, 760 (1982) (Burger, J., concurring)
(judicial review is necessary to maintain checks and balances); cf. Nixon v. United States, 506 U.S. 224,
235 (1993) (judicial review of impeachment process used by Senate eviscerates the system of checks and
balances because impeachment is among the few checks on the judiciary); id., at 241-44 (judicial review
of impeachment process used by Senate is consistent with checks and balances).
b. Balance-of-Power
Separation-of-functions alone, however, does not fully describe the content
of the consensus. On the other conception, power has its more colloquial meaning:
strength, sway, or influence over another. Call this the balance-of-power conception.
The concern is the accumulation of too much strength in a single sphere of
government, and the resulting imbalance of power. Competition and tension among
the departments play a crucial role in most versions of this conception: balance among
the departments is maintained through the creation and maintenance of tension and
competition among them. Such inter-branch rivalry prevents one department from
accumulating excessive governmental power, apparently because rivalries will prevent
collusive behavior (concentrating all of the political power in one of the spheres of
government) among the three entities. The Constitution’s grant of specific powers
to permit the checking of one department by another (the limited Presidential veto,
the Senate’s confirmation powers, Congressional impeachment powers, and, at least
today, federal courts’ power of judicial review ) are critical because those are the117
formal means by which departments protect themselves and limit their rivals. But, by
themselves, these formal mechanisms are no guarantee of balance of power. It is the

rivalry and tension among the departments that assures that those checkingmechanisms will be used to maintain an appropriate balance among the departments.
Just how tension and competition are created and maintained is never clearly spelled
out by courts or commentators. Apparently, rivalries among the departments will
arise naturally out of the tripartite governmental system that the Constitution
establishes. That system is expected to generate the following incentives: individuals
in each of the institutions will have an interest in jealously protecting the prerogatives
of their home department and vigorously resisting efforts by those in other
departments to expand their influence.
Like the separation-of-function conception, the balance-of-power conception
is familiar and can be detected in many references in case law and commentary. Our
system is so often described as a way of creating a balance of powers among the
departments-- “separation of powers and checks-and-balances” goes the stock 118
phrasing--that is it easy to gloss over the assertion. As Justice Kennedy put it in his
concurrence in the line-item veto case: “Separation of powers helps to ensure the
ability of each branch to be vigorous in asserting its proper authority. In this respect
the device operates on a horizontal axis to secure a proper balance of legislative,
executive, and judicial authority.” And, usually, balance is thought to be maintained119
through tension and competition among the departments. Madison (again) is the
source of some of the oft-repeated phrases associated with this aspect of the
conception. He relied on the idea of a competitive system of government institutionswhen he wrote in THE FEDERALIST NO. 51 that each department must be given “the
necessary constitutional means and personal motives to resist encroachments of the
others.” As Madison famously advised, the personal ambitions of members of each120
department were critical to this system: “[a]mbition must be made to counteract
ambition” ; “the interest of the man must be connected with the constitutional rights121

‘separation of powers’ came to connote something far more subtle and intricate than a mere, abstractly
logical division. The phrase expressed the expectation that, through the carefully orchestrated dispositionand sharing of authority, restraint would be found in power counterbalancing power.”) (“The peculiarly
American conception of separation of powers that they [the founders] developed sought balance, not
stasis.”) While Abner Greene rejects the label “functionalist” or “realist,” see Greene, supra note ___,
at 124, his account of the meaning of separation of powers--which is grounded in the framer’s principles--
endorses the idea that the system is intended to achieve a balance among the departments of government.
See Greene, supra note ___, at 138 (“The bottom line was not strength in the executive, but rather
of the place.”122
Today, not only are these Madisonian phrases repeatedly invoked, but their
echo can be heard in the Supreme Court’s habitual reference to separation of powers
as a “self-executing safeguard against the encroachment or aggrandizement of one
branch at the expense of another.” Balance is identified here as the objective of 123
the system; why seek to protect against encroachment or aggrandizement unless
equilibrium among the departments is the objective? But the reference to the system
as “self-executing” is obscure. The critical ingredient to a self-executing system
would seem to be the tension and competition that will inhere in that system; if those
in different departments consider themselves rivals, then they will automatically
exercise the powers available to them to protect their own department’s prerogatives
and to resist efforts by other departments to expand their power.
This balance-of-power conception is not confined to the case law; it can be
detected in functionalist and formalist commentary. Functionalist commentators
subscribe to the idea that the system of separation of powers is designed to maintain
balance among the departments. For the leading functionalist commentator, tension124
and competition among the departments is the way to achieve that balance. As Peter
Strauss writes, his approach “stresses the continuance of opposed, politically powerful
actors at the apex of government.” But it is not only functionalists who lean on this125

balance among the departments of government).
'Balance’ is a word formalists are unlikely to use because of its association with functionalist126
analysis. Formalists eschew the functionalists’ standard-like approach which, they think, will permit (if
not encourage) a court to validate any arrangement before it. See, e.g., Redish, supra note ___, at 100
(“‘Pragmatic formalism,’ on the other hand, is a street smart’ mode of interpretation, growing out of a
recognition of the dangers to which a more ‘functional’ or ‘balancing’ analysis in the separation-of-

employed with principled limitation, any such interpretational approach inherently guts the prophylactic
nature of separation-of-powers protections, so essential a part of that system.”); Liberman, supra note

invoked, see Morrison v. Olson, 487 U.S. 654, 698 (1988) (Scalia, J., dissenting) (Referring to

2. Historical Antecedents of Today’s Conceptions: Distinct and
Conflicting
That there are distinct conceptions of the principle of separation of powers
should come as no surprise. The Constitution, after all, is a blend of two different
theories about the design of government: separation of powers--the idea that the
functions of government should be exercised by separate personnel in separate
governmental institutions--and so-called “checks-and-balances”--an idea that traces
its origins to the classical theory of mixed government, and mixed government’s later
manifestation in England’s mixed or balanced constitution. Even though they have129
evolved considerably, the two conceptions contained within today’s consensus bear

McDonald, supra note ___, at 84-85 (“It is important to notice that Montesquieu’s theory of the
separation of powers is not only different from but is also nearly irreconcilable with the English idea of checks and balances. In the English scheme of things judicial power was exercised mostly by the King’s
courts, but for certain purposes both the Lords and the Commons had judicial authority; and several
traditionally executive powers, including control of the military and the currency, had for practical
purposes devolved upon the Commons. In principle, the British constitution provided for separation of
personnel, rather than for division of function, and even that principle had come to be largely disregarded

these two models of government is a necessary precursor to understanding the
American effort to blend the two ideas. More importantly for our purposes, this
excursion is necessary before we can understand difficulties of the present consensus,
and, in particular, our failure to notice the differences and tensions between the two
conceptions that are now incorporated into that consensus.
The U.S. Constitution’s famous blend of two different governmental designs
was not an easy intellectual feat. As Gordon Wood observed, “[this new130
[American] interpretation . . . was tending to blur the once distinct theory of balanced
government among social orders with the doctrine of separation of governmental
departments.” The fusion was uneasy because of the independence of and tensions131
between the theories of separation of powers and mixed or balanced government.132

See Gwyn, supra note ___, at 37 (“Among the doctrines attaining some prominence at this time
[following the outbreak of the English Civil War] was that of separation of powers, which arose out of
republican dissatisfaction with the manner in which England was being governed by the Long
Parliament.”); Vile, supra note ___, at 36 (“This idea [separate functions exercised by separate
governmental bodies] did not spring into men’s minds from nowhere; they were led into it through the
process of adapting the familiar, age-old theory of mixed government to the problems they faced, and
finally, when they found this theory to be no longer relevant to their situation, they replaced with the new
ideas it had fathered.”); id., at 58. See also Rakove, supra note ___, at 246 (“Both theories [mixed or
balanced government and separation of powers] emerged from the great disputes of the mid-seventeenthcentury--the era of revolution and regicide, Long Parliament and Commonwealth, the Protectorate of
Oliver Cromwell and the Restoration of Charles II. Responding to the royalist reliance on mixed
government in the escalating conflict of the 1640s, several supporters of Parliament first sketched a theory
of separation of powers. In their view, the most objectionable prerogatives were those than enabled the
kind to govern without Parliament, veto legislation, and suspend or dispense with duly enacted statutes.
If these powers were abrogated, the Crown would be restricted to truly executive functions.”)
Indeed, the ideas were considered competing blueprints for governmental design.133
W.B. Gwyn’s admired intellectual history of separation of powers points to the
independence of the ideas, both analytically and historically: “Logically the conception
of the balance of governmental powers is distinct from that of separation of
governmental functions, and . . . the two concepts had historically been entertained
independently of one another.” Gwyn and others who have described the early134
intellectual history of separation of powers ideas (a century before Montesquieu’s
influential 1748 exposition in The Spirit of the Laws) explain that separation of
powers notions developed in response to the series of constitutional crises in
seventeenth century England. In that sense at least, the theory of separation of 135
powers can be seen as an effort to find an alternative to or modification of mixed
government as conceptualized in seventeenth century England.

TODAY Chapts. 2, 7 (1999).
The differences between the two models of government organization can beseen most starkly in the definitions of their pure forms. A government based on
thoroughgoing separation-of-powers would have three departments of government;
each department would exercise one of the three functions of government--legislative,
executive, judicial; there would be separation of personnel among the departments;
and there would be no blending of the functions among the departments. There are136
a variety of reasons for so separating governmental functions. At the highest level137
of generality, though, a system of separated powers is after a familiar liberal end:
controlling, and making safe, the exercise of state power.
Mixed government has that same objective, but it is satisfied differently.
Mixed government is not organized around identification and institutional separation
of governmental functions. Rather, it is based on the participation of different social
orders of society in lawmaking. In its classical formulations, in Aristotle’s Politics138
and Polybius’s Histories, the ideal constitution permits each of the classes of society
to participate in lawmaking. Such an arrangement would, among other benefits,
control the exercise of state power and create a stable governmental system. Each of
three classes of society--the one, the few, and the many (or, to put the classes in the
later vocabulary of the estates of the realm: the king, the lords, and the commons)--
must play a role in lawmaking and in that way, no one class can impose its will on the
others. Mixed government is superior to the natural forms of government for each
of the three classes: monarchy is the natural form of government for the one (or thecrown), but that risked tyranny; aristocracy is the natural form for the few (or the
aristocracy), but that risked oligarchy; and democracy is the natural form for the many
(the commons), but that risked “extreme democracy,” that is, anarchy or mob rule.
Mixed government is the solution: through a mixture of monarchy, aristocracy, and
democracy, each of the social orders participates in lawmaking, and no one of the
classes can impose its will on the others; state power will be controlled, made safe,

practice that was deep-seated in the Western world, namely, an almost mystical habit of thinking in threes.
In part the habit may have stemmed from the concept of the Holy Trinity; in part it doubtless stemmed
from Aristotle’s division of forms of government into monarchy, aristocracy, and polity or constitutional
democracy (with their counterpart evils . . . ). Yet another source was the practice, which was apparently
common to all Indo-European societies, of dividing all men into three classes: those who fight, those who
and government will be stable.139
Translated to seventeenth century England, on the eve of the formal start of
the Civil War, the mixed constitution--as famously declared in Charles I’s 1642 His
Majesties Answer to the Nineteen Propositions of Both Houses of Parliament --meant
that “the government of England is vested in three estates, the king, the lords, and the
commons, and. . .the health and very survival of the system depend upon the
maintenance of the balance between them.” This was a dramatic re-explanation of 140
the nature of the British constitution, from an asserted divine right to rule vested in
the monarch (asserted by Charles I just two years before) to a balance among the
estates, with the crown among the estates to be balanced. As J.G.A. Pocock explains,
after Charles I’s answers, “government is a contrivance of human prudence, blending
together three modes of government--the only three that can exist--each of which
possessed its characteristic virtues and vices. . . . This blend is a balance, an
association in which each partner contributes its particular virtue, while inviting the
others to check its particular vice.” Crown-in-parliament is thus explained as a141
manifestation of mixed or balanced government.
The differences between the two ideas should be evident. To be sure, both are
united by the objective of controlling the exercise of governmental power. And there
is the uncanny presence of categories of three in each of the systems--three social
orders, three functions of government. But the categories of three are, to state the

See Vile, supra note ___, at 166 (“Thus was the whole emphasis of the mid-eighteenth-146
century theory of the balanced constitution transformed. The ideas and vocabulary that had formerly been
applied to monarchy, aristocracy, and democracy were firmly transferred to the legislative, executive, and
judicial branches of government.”); Wood, supra note ___, at 453 (“The `proper Balance in the threeCapital powers of Government’ that men now spoke of was not always that of monarchical, aristocratic,
and democratic elements of a mixed polity, but often that of the executive, legislative, and judicial
functions.”) (describing evolution of idea as of early 1780s); id., at 602-615; id., at 604 (“Americans had

obvious, different. The divergence between the ideas is starkly illustrated by thedistribution of lawmaking power. In a mixed or balanced system, the three estates
must all participate and hence be “balanced” against one another in the lawmaking
body. Thus, not only does parliament represent through its separate houses the
aristocracy and the commons, but the monarch participates in parliament, the latter
being a clear departure from pure separated functions. In a separation of powers
system, the legislature, by itself, is charged with the task of legislating.143
The U.S. Constitution is a famous fusion of these two ideas. Remnants of 144
each design, though importantly modified, are identifiable. The first three articles of
the Constitution institute a separation of powers system by identifying three types of
governmental power, allocating them to three different departments, and providing
for separation of personnel among the departments. Though there are traces of 145
mixed government’s three estates in the three departments, the departments, it should
be emphasized, do not represent the three social orders as in mixed government.146
Instead, the three institutions are identified by their assigned tasks, not by their
representation of a social orders. The first three articles also establish what we have
come to call “checks and balances,” namely, some departures from functional

separation--limited Presidential veto, Senate’s advice and consent, Congress’simpeachment powers--so that one department can check another. Those departures147
from separated powers, and the checking and balancing that such departures are
designed to bring, are drawn from the mixed government tradition, shorn, of course,
of the class bias of that system.148
Today’s conceptions, as sketched here, resemble the two pre-constitutional
ideas, as they were fused together in the Constitution. There is an emphasis on
classifying and institutionally separating the functions of government (separation-of-
functions) as well as a modified version--without the class bias--of mixed government
(balance-of-power). Historians have written about the Constitution’s marriage of
these two ideas. Suffice it to say that the marriage is a troubled one. One difficulty149
in the transition from the European idea of mixed government to the U.S. version is
worth noticing here because of its relevance to the problems with the present
consensus. In a mixed or balanced system, the balance is among the different classes
in society. That balance works, in theory, because one expects that a person drawn
from a social class will have allegiance to that class and, also, may hold particular
views as the result of affiliation with his class. Hence, if all the social classes
participate in lawmaking, no one can impose its will on the rest.150
In the modified U.S. version of mixed government, the balancing is among
functionally differentiated institutions, not social classes. How functionally-differentiated institutions can be “balanced” remains a puzzle: how can the executive
and legislative departments be considered “balanced”? Moreover, the mechanism by
which that balance is achieved is obscure. In the mixed system, one drawn from a
social class can be expected to have allegiance to that class. In the modified U.S.
version, it is likewise assumed that individuals in each institution will have allegiance
to their home institutions, and hence jealously guard the prerogatives of that
institution. But how is it that individuals in functionally-differentiated institutions will
have the same level of loyalty--akin to the allegiance one might have for her own

social class--to the institution in which they find themselves? Perhaps they do, but theconditions creating that sort of loyalty are obscure and, as a result, the arrangements
that might threaten that allegiance are not identified. The transitions, then, from
balanced classes to balanced powers and from loyalty to class to loyalty to institution
are not simple ones.
Noticing the similarities between today’s conceptions and their forerunners
should not obscure important evolution in the ideas. In particular, today’s balance-of-
power conception usually leans heavily on the idea of competition and tension among
the departments of government to achieve balance. The idea of competition and
tension can be traced to the founding articulation of the U.S. system: Madison’s
reference in THE FEDERALIST NO. 51 to the “necessary constitutional means, and
personal motives, to resist encroachments of the other” departments evokes the151
image of competitive system. Even so, emphasis on tension and competition has
virtually taken over the balance-of-power conception and that emphasis has a modern
cast about it.
B. Today’s Muddling of Distinct and Conflicting Conceptions
Whatever the relationship between the historical precursors and today’s
conceptions, they do share one similarity: just like their historical forerunners,152
today’s conceptions of separation-of-functions and balance-of-power areinappropriately muddled together. As this Part demonstrates, the two conceptions are
conflated or, if not conflated, treated as if they obviously relate to one another. But,
as this Part also demonstrates, this is a grave mistake: they are distinct conceptions,
their relationship to one another is not obvious, and, in some respects, they are in
tension. Not surprisingly, then, efforts to conceptually connect the two ideas prove
fruitless. And the two ideas suggest different, even irreconcilable, doctrinal concerns
that should animate courts as they consider separation of powers questions. As this
section will thus demonstrate, the consensus is attempting the impossible: subscribing
simultaneously to these two distinct conceptions.
1. The Phenomenon: Conflated, or Complimentary, Conceptions

Id. at 106.157
The two conceptions associated with the distinct meanings of power are oftenconflated or treated as obviously related. Consider some illustrations of this tendency.
The Supreme Court’s repeated invocation of “separation of powers and checks and
balances” as a “self-executing safeguard against the encroachment or aggrandizement
of one branch at the expense of another” fails to identify the differences between153
functional separation and balance. Moreover, the reference collapses both strategies
into one objective: safeguarding against encroachment or aggrandizement, in other
words, balance. The same impression is provided by Justice Kennedy’s concurrence
in the line-item veto case, where he wrote that “Separation of powers helps to ensure
the ability of each branch to be vigorous in asserting its proper authority. The device
operates on a horizontal axis to secure a proper balance of legislative, executive, and
judicial authority.” Again, the system of separation of powers is equated with154
balance among the departments.
Nor is this practice limited to the courts. One commentator fully equates
functional separation with balance, arguing that the founding understanding of
separation of powers was “balance between the departments, secured through a
division of power.” Another commentator notes that preserving political liberty155
requires that “the legislative and executive powers cannot be united in the same
body.” Here is a straightforward statement of the need to separate functions.156
Subsequently, the commentator observes that separation of powers must operate in
such a manner as to “preven[t] a situation in which one branch has acquired a levelof power sufficient to allow it to subvert popular sovereignty and individual
liberty.” Does “level” of power mean, solely, the exercise of more than one157
function of government? It is not clear. The former quote refers to the need to
separate powers and the latter quote refers to the need to balance powers, suggesting
that they are the same thing. The relationship between the two meanings, in any
event, is not made clear.

individualized proceedings, the adjudicator should be insulated from politics--that Strauss seems to limit
Another set of commentators refers to our system of “fragmented power andinstitutionalized competition.” “Fragmented power” is a reference to the allocation158
of different functions to distinct institutions (separation-of-functions). “Institutional
competition” is a reference to rivalries among the departments (balance-of-power).
Although some relationship is implied, the commentators are not clear whether
separation-of-functions creates that competition. If the two are related, how does
separating functions create institutional competition? If fragmenting power and
institutional competition are not related, how is institutionalized competition created
and maintained and what role does that competition play? The authors appear to
invoke both conceptions, but they, like others, fail to discuss the relationship between
them.
Consider a final example of a conflation of the two conceptions, drawn from
the work of functionalist commentators. Recall that Peter Strauss argues that at the
apex of government--among the President, Congress, and Supreme Court--there must
be functional separation of power; that separation, however, is not necessary for the
subordinate levels of government. According to Strauss, the “text and context”159
suggest that the primary constraint on Congressional design of administrative agencies
is the need to “perpetuate the tensions and the interactions among the three named
heads of the Constitution.” Such tension, Strauss maintains, can be achieved160
without resort to a thoroughgoing separation of functions. Strauss then identifies a
set of requirements for administrative agencies that, he asserts, will guarantee that thetension between the departments will be maintained.161
Strauss’ move is creative, but it does something by-now familiar: it collapses
separation-of-functions into tension, competition and resulting balance. The162

to individualized proceedings. That, however, is too narrow an understanding of the independent reasons
for separating functions. See TAN ___-___ (Part III.C.2.).
See TAN ___-___ (Part III.C.2.).163
See TAN ___-___ (discussing the ways commentators conflate the two ideas); Calabresi &164

(checks and balances approach, which Strauss ultimately defends, “seeks to protect the citizens from the
emergence of tyrannical government by establishing multiple heads of authority in government, which
are then pitted one against another in a continuous struggle; the intent of that struggle is to deny to any
one (or two) of them the capacity ever to consolidate all governmental authority in itself, while permitting
the whole effectively to carry forward the work of government.”)
approach--both for the actors at the apex and the subordinate levels of government--treats functional separation as a way of achieving balance through tension and
competition. But there are reasons to separate functions that are unrelated to tension,
competition and resulting balance among the departments.163
2. Possible Connections and Their Failure
Perhaps the two conceptions are muddled together or conflated because the
connection between them is so obvious that it need not be explicitly stated. That is
the impression one gathers from the literature. Writers imply that one leads to the
other--in particular, that separation-of-functions leads to balance-of-power. To be
clear, statements of the consensus rarely elaborate on the connections between the
components of the system; what that literature offers instead are catch phrases that
imply that the two are related.
Attempting to furnish a connection between the conceptions, however,
demolishes casual confidence about the connection between them. Consider the two
ways the conceptions might relate to one another that are suggested by discussion of
the consensus. First, it may be that the allocation of government functions to different
departments creates the competition and tension that is a key ingredient in most
versions of the balance-of-power conception. Second, allocating government164
functions to different departments, along with the checks like the veto and

Martin Flaherty argues that this idea captures the founding understanding. See Flaherty, supra

developed. See Farina, Statutory Interpretation, supra note ___, at 488-96; Greene, supra note ___, at

generally about the framing of the Constitution, see Wood, supra note ___; McDonald, supra note ___;
and Rakove ___.
impeachment powers, may yield balance among the departments. This latter view165
does not necessarily depend on the mechanisms of tension and competition to assure
balance among the departments; on this view, functional separation, along with
checks, just leads to balance. Consideration of each of the suggested connections
reveals that the neither of these connections holds up.
a. Functional Separation Creates Tension and Competition
Examine first the suggestion that functional separation will lead to competition
and tension and, hence, balance among the departments. No reason is provided why
functional dispersal of power is necessary to the creation and maintenance of tension
and competition among the departments. Consider the following effort to fill in the
details of the supposed causal relationship between the two ideas: Perhaps the
dispersal of governmental powers among institutions creates a type of distinct
institutional identity for each department, and, just as importantly, distinct
constituencies for those institutions. The development of this type of institutional
identity--an identity tied to the functional allocation of power given to that
department--is what fosters the tension and competition among the departments.
Those in a department would naturally identify with the distinctive identity of the
department in which they work. Given the link between the institution’s identity and
the functional allocation of power, this would mean that those affiliated with the
department would be partial to the way in which their own department makesdecisions; and that partiality may extend to a disdain for other departments’ ways of
making decisions.
To select the most obvious of the examples to illustrate this point, consider
the judicial department. The judicial department has a distinctive institutional identity
and it is one that owes much to the assignment of a specific type of authority. Vesting
judicial power in the Supreme Court and lower courts means that individuals with a
particular set of skills comprise the important decision makers in the court system;
8/12/2019 The Real Separation in Separation of Powers Law (SSRN)
http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 49/81
Draft 49
and, individuals with that same set of credentials are among the court system’s mostimportant constituencies. Moreover, the way in which the judicial power is exercised-
-through cases or controversies--plays a role in creating a distinct institutional
identity. Those associated with the judicial department will favor the modes of
decision making of that department and may harbor some disdain for the decision-
making of the executive and legislative departments. On this telling, functional
allocation helps create a distinctive institutional identity, one that carries with it the
prospect of tension and competition among the departments.
That same type of distinctive institutional identity could likewise have
implications for interest groups in a way that would foster competition. As a result
of institutional identities that arise from functional power dispersal, some interest
groups would be more influential or effective in particular spheres of government.
Consider again the best example: the vesting of judicial power in the Supreme Court
and lower federal courts. This functional allocation means that attorneys have a
unique relationship with the judicial department. That relationship is complicated, of
course, but at a minimum one would expect that lawyers, or those who represent
them, will have a natural interest in seeing the judicial department have a certain
amount of authority, and in defending its prerogatives if they are threatened by other
departments. On this understanding, separating functions is an important ingredient
in generating tension and competition.
But if this all sounds speculative, it is. Distinct institutional identities that arise
from the allocation of government functions may be an ingredient in fostering tension
and competition. Then again, one might question whether functional separation is
necessary to the development of distinct institutional identities. One can easily
imagine competition and tension among departments without any functional
differentiation. Imagine three separate institutions all devoted to a functional task
called lawmaking. All are assigned the same job of making law, but the three
institutions have different structures: distinctive selection systems (elected on a local,
state, or national basis; or, appointed), varying terms of office (2 years, 4 years, 6
years, life tenure), different internal structures, and--largely, it would seem, as a result
of these differences--different institutional identities. One would expect there to becompetition and tension among those institutions that would arise, not from the three
entities performing different government functions, but as a result of the distinctive
structures, and hence characters, of the institutions.

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 50/81
The Real Separation50
One might even put the argument more strongly: functional differentiationcould actually work to dilute tension and competition among governmental
institutions. As compared to two institutions engaged in the same function,
institutions that are assigned different tasks might be less competitive with one
another--with different tasks, each would have an independent sphere of competence.
Imagine a regime where functional differentiation among governmental institutions
is quite sharp; that sharp differentiation might facilitate cooperation, not competition,
among institutions and deference between and among them based on differential levels
of expertise. The insight is simply that it is natural to be most competitive with those
who perform the same function, and, as a relative matter, less competitive with those
who perform different tasks. The world’s fastest runner is not as competitive with the
world’s fastest high jumper as he is with the world’s second-fastest runner.
b. Functional Separation Leads to Balance
Consider now the second possible connection between the two conceptions.
On the second view, functional dispersal of governmental authority--along with the
limited Presidential veto, advice and consent, impeachment powers--yields balance.
The view is appealing. To claim that it is the separation of functions that yields a
balance among the departments of government is to establish a benchmark (proper
allocation of those governmental functions) against which courts might conceivably
determine whether the objectives of the doctrine have been achieved. In establishinga benchmark this view escapes the difficulties associated with the more free-floating
objective of balance through institutional competition in the usual versions of the
balance-of-power conception.
The difficulty with this understanding, however, is that it does not specify
what is meant by balance. The dispersal of governmental functions--along with the
defensive or protective powers such as the limited veto, advise and consent, and
impeachment powers--mysteriously leads to balance, but the assumptions under which
that balance occurs are obscure, or, to say the same thing differently, what constitutes
balance is unstated. Surfacing what must be a prime assumption under which this
understanding operates, however, undermines confidence in the understanding. To posit that the dispersal of functions will lead to a balance of governmental power must
assume that the three powers are roughly equivalent in strength. The assumption
must be that dispersing the functions (and arming each institution with limited ability
to defend itself) will lead to a balance in political power among the departments of

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 51/81
Draft 51
government.
At worst, this premise seems fanciful. It is simply not plausible to think of
legislative power, on the one hand, and executive and judicial power, on the other, as
even roughly equivalent powers. In the domestic sphere anyway, the legislative
power must be considered the dominant power--dominant in the relative sense that
the executive and judicial powers can be said to be subordinate to it. That is because
the legislature has the authority to define the general norms governing the behavior
of those outside the legislature and its policy determinations are authoritative, except
for that rare case where a court deems the legislature’s choice unconstitutional. The
executive’s role in the implementation of statutes, and the judiciary’s role in the
adjudication of disputes arising under statutes, are subordinate to that of the
legislature: both entities, in exercising their tasks, are to discern and adhere to the
determinations made by Congress. Any student of executive and judicial decision-
making, at least a post-realist student of such decision-making, knows that there is
much play in the joints when a decision maker is engaged in the task of implementing
the law or interpreting the law. And the executive power includes the Commander-in-
Chief power and special powers in defense and foreign affairs and times of emergency;
the federal judiciary, too, has the power of judicial review. Even with these caveats
and limitations in mind, in the domestic sphere, the legislative power must be
considered the dominant power in the sense that implementation of the law and
adjudication of disputes arising under the law involve an effort by the executors andthe interpreters to discern and effectuate Congressional will.
Even if this strong version of the critique is not accepted, the connection
between separation-of-functions and balance-of-power needs much more elaboration.
The meaning attributed to balance is unstated; and the method by which we might
compare the strength of apples and oranges like executive, legislative, and judicial
power--and pronounce them `balanced’-- is obscure.
3. The (Predictable) Doctrinal Impossibility
Not only is it difficult to reconcile the two conceptions abstractly, the two
conceptions suggest different doctrinal concerns that should animate courts when they
examine separation of powers cases. This is no accident. As we just learned,
attempting to merge the distinct conceptions into a coherent set of ideas is a fruitless

The Real Separation52
U.S. CONST. art. II, § 2, cl. 2.166
enterprise. Articulating more concretely the set of doctrinal concerns prompted byeach of the conceptions only furthers that impression.
On the separation-of-functions understanding, courts should worry, first and
foremost, about policing the boundaries among the three functions of government.
Hence, the initial concern in any case should be: how can one characterize the power
at issue? Once characterized, the function must be confined to the corresponding
department, and exercised in that department according to a set of constraints. The
latter steps in that analysis, however, are predicated on--and must be considered
subordinate to--the answer to the primary question about the type of power being
exercised by the government actor or institution. This hierarchy of doctrinal concerns
flows immediately out of the separation-of-functions conception; the core danger to
be avoided -- the “very definition of tyranny,” so goes the phrasing- -- is the exercise
of more than one of the government functions by a single department of government.
By contrast, the balance-of-power conception suggests a different set of
doctrinal concerns. Courts would clearly invalidate any efforts to strip the checks--
the limited Presidential veto, the advise and consent power, the impeachment power--
that one department has over another. Those formal means permit one department
to protect itself and prevent excesses by the other departments. But another set of
concerns would also animate courts: identifying and invalidating arrangements that
undermine the competition and tension among the departments of government. It isthat tension and competition that creates the incentive for actors in the departments
to use the formal checks in the appropriate way. Hence, courts adhering to the
balance-of-power conception should be particularly skeptical of institutional
arrangements that would undermine competition and tension among the departments,
or, to put the point differently, that might facilitate collusion among the departments.
Consider a prominent set of questions in separation of powers law with these
descriptions in mind. A recurrent question is how the Appointments Clause of Article
II should be interpreted. That clause grants the President the power “by and with the
Advice and Consent of the Senate” to “appoint . . . Officers of the United States.”166
A variety of questions have arisen regarding this Clause: the permissibility of Congressional limitations on the President’s ability to remove, at-will, those at the

helm of certain agencies ; the permissibility of direct Congressional participation in167
the appointment or removal of government officials that, for example, administer 168 169
the campaign finance laws or play a role in the Gramm-Rudman-Hollings deficit
reduction statute; and, finally, the permissibility of an independent counsel located in
the executive branch, where the President’s ability to appoint and remove that
prosecutor is circumscribed by statute.170
Adherents of the two conceptions should have quite different approaches to
these cases. First, consider the balance-of-power conception. On the balance-of-
power conception, inter-institutional competition and tension are critical ingredients.
Advocates, however, fail to specify how the system of separated powers actually
fosters and maintains that competition, and, hence, it is difficult to discern what sorts
of arrangements would undermine tension and competition. But among the171
arrangements that would seem to thwart competition and tension--and potentially
permit or even promote interdepartmental collusion--would be arrangements that
weaken the allegiance individuals would otherwise owe to the department in which
they are located. Diminishing loyalty to a single department would dilute the interest
that the officer might otherwise possess to protect the prerogatives of the department
in which she is located and to resist the efforts by actors in other departments to
expand their spheres of influence. On this understanding, then, those who subscribe
to the balance-of-power conception should be wary of Congressional efforts to
weaken the allegiance that an officer would owe to a single department.Arrangements that would weaken the connection between an officer and the
department in which she is located--such as insulating officers from Presidential
control and supervision, either through methods like generally applicable
appointments or removal restrictions or through direct methods such as Congressional
involvement in appointment or removal of specific individuals--should thus be

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 54/81
The Real Separation54
For a different argument, one that is based on a re-reading of Madison’s famous THE172
FEDERALIST NO. 51, that similarly emphasizes the need to foster allegiance between an individual and the
department in which she is located, see Nourse, supra note ___.
To those schooled in the voluminous literature on the Appointments Clause cases, this173
analysis should sound a bit odd. See TAN ___-___ (Part I.B.). That is because separation of powers
formalists are more associated with support for the separation-of-functions conception; yet, they are the
most devoted to the notion that there is a hierarchically organized, unitary executive. See, e.g., Lawson,
The Rise and Rise, supra note ___, at 1241-46; Calabresi & Rhodes, supra note ___, at 1186-1208;
Currie, supra note ___, at 31-36; Miller, supra note ___, at 96-97; Liberman, supra note ___, at 352-58;
Calabresi & Prakash, supra note ___, at 663. At the same time, functionalist commentators, and others
who emphasize balance among the departments, stress the balance-of-power conception. Yet it is thatgroup of scholars that defends Congress’ ability to insulate certain executive department officers from at-
will Presidential removal. See Strauss, Place of Agencies, supra note ___, at 609-616; see also Flaherty,
supra note ___, at 1835-36; Lessig & Sunstein, supra note ___, at 106-110; Greene, supra note ___, at
171-77.
Humphrey’s Executor v. United States, 295 U.S. 602 (1935).174
invalidated on the balance-of-power conception.172
Adherents of the separation-of-functions conception, on the other hand,
should not be as concerned about efforts to insulate government officers from
Presidential supervision and control. To be more precise, adherents of the separation-
of-functions conception should be, chiefly, concerned whether the relevant official or
institution is exercising executive power. If the officer is exercising something173
more than executive power--is, rather, exercising a blend of legislative and executive
powers--then the central concern of the separation-of-functions conception is
implicated. The point is a simple one; on the separation-of-functions conception, the
objective of separation of powers it to assure (subject to the few textual exceptions
contained in the Constitution) that governmental functions are exercised in separate
departments, and thus the first question about a contested institutional arrangement
must be about the type of power exercised.
Consider an example that illustrates this claim about the concern of the
separation-of-functions conception: the permissibility of Congressional limitations on
the ability of the President to remove, at-will, members of the Federal Trade
Commission. Certainly, the President has an argument--though not necessarily a174
dispositive one--that, if the FTC is exercising executive powers, then the President

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 55/81
Draft 55
As I suggest in the text, the President’s ability to fire an officer at-will does not inexorably175
follow from a determination that the power exercised is “executive” (assuming for the moment, albeit
heroically, that we could develop a definition of executive power). Resisting cases like Humphrey’s
Executor and Morrison v. Olson, formalist commentators assert--usually without an elaborate defense
of the connection--that an officer exercising executive power must be removable at-will by the President.
See, e.g., Liberman, supra note ___, at 353 (“The grant of executive power to the President must mean
either that he can exercise any law-executing authority himself or direct how it is exercised.”); Calabresi
& Prakash, supra note ___, at 663 (“[S]ince the President’s grant of `the executive power’ is exclusive,
Congress may not create other entities independent of the President and let them exercise his ̀ executive
Power.’”); see also id., at 570-599. The logic behind the connection between the two is rarely spelled
out. But the connection between these two is not automatic. It is a dramatic expansion of executive
power to permit, as we do, the President to delegate, virtually without limit, his executive power to anagent. That expansion might also warrant some limitations on the President’s ability to remove the
officers exercising the delegated power.
There are also many limitations on the ability of the President to remove those in the executive
branch. Formalist commentators, I expect, would accept many of them as permissible. There exists an
elaborate web of laws and regulations associated with the civil service system; those laws limit patronage
and require for-cause removal of some employees. See Mashaw, Merrill & Shane, supra note ___, at
182-88. Even with respect to officers of the United States--those who “perfor[m] a significant
governmental duty exercised pursuant to the public law,” Buckley v. Valeo, 424 U.S. 1, 122 (1976)--
there are restrictions on Presidential removal that I would expect formalist commentators to accept.
Consider two: the President may not fire an officer based on constitutionally impermissible factors (race,
religion, sex); the President may not fire an officer because the President disagrees with the judgment the
officer rendered in an individualized proceeding where the dictates of procedural due process constrain
government decisionmaking. If formalists would accept either of these limitations on the President’sability to remove officers, it means that even formalists don’t adhere to the view that a determination that
an officer is exercising executive power means that the President must be able to terminate her at-will.

must have the ability to remove, at-will, Commissioners of the FTC. But, if the175
Commissioners are not exercising solely executive power, on what basis could the
President assert that he has the right to remove FTC Commissioners at-will? On the
separation-of-function conception, the problem with the FTC is that it appears to
exercise each of the three governmental functions; Congress cannot constitutionally
authorize an entity to exercise such a combination of functions. The removal
restrictions, in light of that prohibition, seem beside the point. This same sort of

v. Valeo. On the separation-of-functions conception, the primary question in each178
of these cases should be whether there is an impermissible blending of government
functions. If a court determines that any of these entities are exercising exclusively
executive functions, then, and only then, should the court reach the independent
question whether the President must be able to remove at-will the officials exercising
that power.
Nor is it simple to argue that adherents of the different conceptions would
pose different questions, engage in different reasoning, and, still, fortuitously, usually
reach the same outcomes. Such a happy coincidence would make it possible to
adhere to the two conceptions at once. If that were the situation across a range of
cases, perhaps we could live with the dissonance caused by the different questions
asked by the two conceptions. No such account, however, holds up in a range of
important cases. Consider the constitutionality of limitations on the President’s ability
to appoint and remove commissioners of the FTC. The adherent of the balance-of-
power conception would argue that the restrictions are unconstitutional because they
dilute the allegiance that the members of the FTC would otherwise owe to the
executive department. And the devotee of the separation-of-functions conception
would argue that the an executive officer cannot preside over an entity that blends the
three governmental functions in one institution. So far so good.
The problem is this: if the allegiance of the FTC Commissioners is notdiminished, if the Commissioners can be removed at-will, then the balance-of-power
conception and the separation-of-functions conceptions diverge. The balance-of-
power conception would be satisfied because, with at-will removal, the loyalty lines
running between the Commissioners and the President are sufficiently strong. On the
other hand, the adherent of the separation-of-functions conception has made
absolutely no progress: an FTC Commissioner who is appointed and removed by the
President at-will would still supervise the exercise of legislative, executive, and
judicial power.
Another example makes this point and illustrates the salience of this
divergence in approach. Consider the constitutionality of the of the United StatesDepartment of Agriculture. The Department is headed by a Secretary who serves at

See, e.g., Rules of Practice Governing Formal Adjudication Proceeding Instituted by the180

Accountability is not generally among the meta-objectives--like those elements of the181
consensus position that I have identified--that adherents of the consensus position ascribe to the overall
system of separation of powers. Rather, its role is usually as a subordinate objective related in particular
to the assignment of, as those who favor the unitary executive position would emphasize, “the” executive
power to single President. This is not to say, however, that the accountability value is unrelated to theselarger meta-objectives. See Calabresi, Some Normative Arguments, supra note ___, at 45-48. For a
sampling of the discussion of the accountability value, see, e.g., Lessig and Sunstein, supra note ___, at

the pleasure of the President. The balance-of-power conception is not concerned179
about the Department because the allegiance the Secretary owes to the executive is
not diminished through removal restrictions. By contrast, for the adherent of the
separation-of-functions conception, the Department would seem to be
unconstitutional: the Department engages in rulemaking, enforcement, and
adjudication. It thus represents the worst case scenario, that is, the accumulation180
of all governmental functions in a single institution. No at-will employment
relationship between the Secretary and the President can cure that defect; that defect
is the core eventuality the separation-of-functions conception seeks to protect against.
It is, in short, no simple matter to apply the distinctive questions in cases and reach--
even on different reasoning--the same outcomes.
This discussion of the approaches that should be taken under the balance-of-
power conception or the separation-of-functions conception is not intended to suggest
that these are the only lenses through which to consider the question of the
permissibility of insulating executive officers from at-will removal by the President.
There is another value, usually called accountability, that is invoked when the question
concerns the organization of the executive department. Commentators uniformly181

feature of most of the `unitary executive’ literature that it gives little sustained attention to what
`accountability’ means.”)
There is a meaning of accountability that has historically been associated with separated powers.
W.B. Gwyn describes this “accountability” version of separation of powers and it is quite different from
what contemporary writers mean when they praise accountability in the executive. This version focused
on the legislature’s power to “call to account the non-legislative personnel of the government should they
misuse their power.” Gwyn, supra note ___, at 16; see id., at 16-17, and 42. That idea of accountability
is embodied in the impeachment powers vested in Congress.
See Calabresi, Some Normative Arguments, supra note ___, at 58, 81-86; Shane, supra note183
___, at 196.
See Bruff, supra note ___, at 506-07; Sargentich, Limits of the Parliamentary Critique, supra184
note ___, at 718 (observing that accountability argument, which Sargentich ultimately criticizes, “rests
on the premise that accountability requires unity in government so that the people will know whom to
hold responsible for success or failure”); Lessig & Sunstein, supra note ___, at 98; Calabresi, Some Normative Arguments, supra note ___, at 42-45.

OF CHI. L.R EV. (forthcoming). As these commentators argue, accountability rests on unproved empirical
assumptions and is weakly conceptually developed. See id., at 14; Shane, supra note ___, at 197-209.
praise this value. Unfortunately, it is not exactly clear what they are praising.182
Sometimes, those who value accountability focus on the relationship between a
governmental official and her superior. When accountability is invoked in this way,
the argument is that the President must be authorized to fire an official exercising
policy making authority in the executive department; it is through that form of
supervision, so the argument goes, that those who exercise governmental authority
can be monitored and controlled. At other times, accountability refers to a more183
general concern about the relationship between the government and citizens. The idea
when this version is invoked is that there must be a hierarchically organized executive
department--one where the President can fire at-will any policy making official--so
that there will be clear responsibility for governmental actions. If citizens know who
to praise for accomplishment and who to blame for failure, they can properly monitor
the exercise of governmental power.184
Many have observed that accountability, as presently conceptualized, is a
troubled concept. For our purposes, however, it is only important to observe that185

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 59/81
Draft 59
Nor is it clear that whatever commentators mean when they invoke this value can be achieved through
the creation of a strong executive, see Farina, Consent of the Governed, supra note ___.
accountability does not make the two conceptions studied here compatible with oneanother, nor is accountability a value that stands on its own--and could thus replace
the two conceptions studied here--as an understanding of separation of powers. One
could be a fan of accountability in the organization of the executive department and
believe that view requires the President to be able to fire any officer at-will. That
view seems most consistent with the balance-of-power conception described here.
This view, however, implies nothing about support for the separation-of-functions
conception. One might support a hierarchically organized executive department and
not be committed to separation-of-functions; or, one might support a hierarchical
executive department and independently value separation-of-functions. The two ideas
do not have to travel together. Nor can accountability, by itself, provide a complete
account of separation of powers. To place a premium on accountability is not to say
anything about the functional dispersal of government authority, nor does it
necessarily say anything about balance among different branches. Imagine a single
elected head of state that presides over an executive department that exercises all
governmental power. There is no separation of functions; there are no separate
departments to balance against one another. Yet, there is full accountability.
C. The Conceptual Consequence of the Muddle
The previous section demonstrated that the consensus contains two
conceptions of separation of powers that are housed uneasily together. Muddling thetwo has meant that we have failed even to notice, much less to evaluate, the two
distinct substantive conceptions of separation of powers. This section will identify the
profound conceptual consequences of the confused and conflicted consensus. Those
consequences include a general failure to articulate basic elements of the objectives,
means, and mechanisms of separation of powers; confusion about the separation-of-
functions conception; and a lack of development of the balance-of-power conception.
1. Vacuous Defenses of Separation of Powers
The muddling of the distinct ideas helps explain, on a general level, the
unsatisfactory state of separation of powers case law and commentary. That case law,and to a lesser extent the commentary, is peppered with airy phrases that tell us little.

Consider a few examples. There is Justice Jackson’s famous statement, quotedrepeatedly in Supreme Court cases: “While the Constitution diffuses power the better
to secure liberty, it also contemplates that practice will integrate the dispersed powers
into a workable government. It also enjoins upon its branches separateness but
interdependence, autonomy but reciprocity.” Likewise, recall the two phrases186
associated here with the distinct conceptions, also cited repeatedly in separation of
powers cases. There is, on the one hand, the “political truth . . . stamped with the
authority of . . . enlightened patrons of liberty,” namely, that “the accumulation of 187
all powers legislative, executive and judiciary in the same hands . . . . may be justly
pronounced the very definition of tyranny.” And, there is, on the other, the opaque188
statement examined earlier: the “system of separated powers and checks and
balances” acts as a “self-executing safeguard against the encroachment or
aggrandizement of one branch at the expense of another.” For their part,189
commentators muddle the two conceptions together and are hence not much more
helpful than the courts. Readers of these phrases do not know what they mean,190
nor do the phrases seem to do any work in resolving particular cases. There is, in
short, an astonishing lack of ability to identify in any concrete way--that is, beyond
avoiding “tyranny”--the objectives of the system, the components of the system, or
the way in which that system works to achieve its objectives. It is perhaps the
nebulous nature of the explanations of our system that prompted one astute observer
to remark: “The principle of [separation of powers] has been effusively praised and
on occasion vigorously enforced. But just what is it?”

tyranny”); see also TAN ___-___ (Part III.B.1.). For a commentator who does identify with some
precision the reasons for functional separation, see John F. Manning, Constitutional Structure and
Judicial Deference to Agency Interpretation of Agency Rules, 96 COLUMB. L. R EV. 612, 645-48 (1996).
See, e.g., Redish, supra note ___, at 99 (separation of powers is “designed to reduce the193
obvious dangers that flow from the concentration of political power”); id. at 105 (“No critic has
adequately demonstrated either that the fears of undue concentrations of political power that caused the
Framers to impose separation of powers are unjustified, or that separation of powers is not an important
means of deterring those concentrations.”); id. ( “After all, no one can predict with certainty that, but for
the formal separation of branch power, the nation would be likely to sink into a state of tyranny.”)
But the conceptual difficulties of the current consensus go beyond a generallack of precision in separation of powers talk. As the next two parts demonstrate, the
muddle has meant that the reasons for, and critical thinking about, each of the
conceptions remains deficient. To preview those deficiencies, the reasons for
institutional separation of government functions are rarely provided; when reasons are
offered, they either do not map on to a command to institutionally separate functions,
or they collapse separation-of-functions entirely into a means of balance and checking.
As for the balance-of-power conception, the meaning of balance among functionally-
differentiated departments is obscure; and, the mechanisms by which tension and
competition are created and maintained, much less threatened, are not identified.
2. Confusion about Separation-of-Functions
Those who extol the importance of separating government functions rarely
explain what, exactly, is wrong or dangerous about a combination of functions.
Adherents usually just repeat that Montesquieu-Jefferson-Madison phrase
(combination of functions is “the very definition of tyranny”) to supply a reason for
separating functions. Functional separation, at the institutional level, is a way to192
prevent “tyranny,” but how so?
The most often-stated goal is to achieve the dispersal of power, to avoid, as
the courts and commentators say, the concentration of political power. Repeated
193
use of that ambiguous word, power, sheds little light. There is this obvious point:
8/12/2019 The Real Separation in Separation of Powers Law (SSRN)
http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 62/81
The Real Separation62
separating functions is not necessary to disperse power . That is, power can bedispersed without insisting that there are three different types of governmental power
that must be allocated to three different institutions. Consider the most obvious
examples: bicameral or multi-cameral legislatures. Both are examples of power
dispersal that do not rely on functional distinction. In our system, both the House and
the Senate must concur in legislation before it is presented to the President; in that
way, power is dispersed, but, still, each body exercises legislative powers. Federalism
provides another example: that is power dispersal, largely (though not exclusively)
without functional differentiation in tasks. So too with court systems in which all
levels of a hierarchical system are exercising judicial power, and, yet, that judicial
power is dispersed among them. Or, consider a multi-member court: each judge
exercises judicial power, but, again, there is power dispersal because it takes a
majority or plurality to control the outcome in a given case. Examine one final
example: vesting the power to execute federal law in the hands of executive officers--
as opposed to vesting all such power in the President. This is a way of dispersing
executive power among different parts of the executive department. Hence,
empowering the Attorney General (rather than the President himself) to make a
decision under a statute--say, whether to waive deportation of an individual based on
a set of statutorily specified factors--is a way of dispersing executive power.
A corresponding point can be made about the phrase “concentration of
power.” Just as there are different ways of dispersing power, there are different waysto concentrate it. One way of concentrating power would be to limit the number of
entities that exercise a particular task. As compared to a multi-cameral legislature,
bicameral or unicameral legislatures are concentrations of power because fewer
entities exercise legislative power. It would also represent a concentration of power--
in the hands of the President--to halt the practice of vesting authority in officers of the
executive branch.
There are thus ways of dispersing power that do not require functional
separation and ways of concentrating power that do not depend on the merger of
functions. On the separation-of-functions conception, however, it is crucial to
prevent one institution from exercising more than one type of function. Whatdistinctive explanation can be offered for a command to institutionally separate
governmental functions?
A familiar reason to separate functions can be ruled out as the primary

justification for the separation-of-functions conception, at least today. One reason toseparate functions is to encourage specialization in the performance of those
functions, thereby promoting efficiency. Just as we might, for efficiency reasons,
assign different tasks to groups of workers who are engaged in the process of building
a car so that each group could master its own assigned task, rather than every worker
having to master the many different tasks, we might parcel out governmental
functions to different institutions. This efficiency justification was historically thought
to be one of the reasons to separate functions. But, among today’s adherents of the194
consensus position, fostering a more efficient government is certainly not the primary
justification for separating governmental functions. In fact, one of the dominant
modern criticisms of separation of functions relates to its inefficiency ; defenders of 195
the system, in response, largely concede the point and turn it around--they cast
inefficiency as a virtue, not a vice, of the system. Separating functions is designed196
to do something to protect the citizenry from the government (and not simply to
protect it from waste). It is aimed at preventing governmental over-reaching (or, to
invoke that over-used word, tyranny).
Another justification for institutionally separating functions can be called the
coordination thesis. The idea is this: separating functions is necessary so that three
different institutions agree before the government can injure an individual. In one
form or another, this thesis frequently appears as a defense of separating functions.197

general policy and ends with the translation of this policy into a final determinations of consequences for
particular individuals. The ability to monopolize this process--to decide policy and to control its
implementation in particular cases--would seriously threaten individual rights and liberty. The separation
of powers lessens this threat by dispersing government authority: it divides the lawmaking process into
three distinct phases and requires affirmation from a separate entity in each phase. No single
governmental body can gather too much power if successful completion of the process requires the
participation of the two other, independent bodies.”); Manning, supra note ___, at 645-646 (“When the

David Currie offers a resonant version: “The distribution of these powers among threeseparate branches serves as a powerful check against arbitrary action, for it means that
three distinct bodies must concur before the individual is effectively deprived of liberty
or property: Congress must pass a law, the President must seek to enforce it, and the
courts must find a violation.” This thesis is worthy of extended analysis because198
it is a common--even pervasive--reason given for institutional separation of
government functions. Sometimes, this defense of separating functions is presented
(like Currie’s formulation) as about preventing arbitrary government action ; other 199
times, while the idea is the same, it is unveiled in different dress--separated functions
as a way to check and balance the exercise of power, to limit factions, or to200 201
promote deliberation.202
The coordination thesis does not work as a justification for institutional
separation of functions. On one reading, the thesis is just a variation on the argument
that government power should be dispersed. The insight is that a single institution
8/12/2019 The Real Separation in Separation of Powers Law (SSRN)
http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 65/81
Draft 65
should not control all governmental power; to avoid that, the system provides threedifferent authoritative decision-makers. As just demonstrated, however, dispersing
political power does not require that power be classified into three categories and
assigned to separate institutions. To disperse power, there must be more than one
authoritative decision maker, but functional separation is not necessary. Arbitrary
action can guarded against by requiring that three institutions--all engaged in the same
function called lawmaking--concur before liberty or property is taken from an
individual. It might be logical or convenient to say those institutions are exercising
different types of power. But, classification of government power into three
categories and dispersal of it among different institutions does not play a distinctive
role on this understanding.
On another reading, however, the coordination thesis envisions the separate
exercise of government functions itself as crucial to the prevention of arbitrary action.
This version suggests that it is the allocation of distinct powers to separate institutions
that provides the mechanism for preventing arbitrary action. It is not enough, then,
to have three policy-makers who must concur before liberty or property is deprived.
Instead, to prevent arbitrary action, there must be multiple decision-makers endowed
with distinctive government powers--making law, enforcing law, interpreting law. On
this view, the exercise of the executive power checks the exercise of the legislative
power; and the exercise of the judicial power checks both the executive and the
legislative power. To illustrate, Congress passes a law that is arbitrary; the executivemay choose not to enforce the law based on that ground; and, if the executive does
choose to enforce the arbitrary law, the judicial department may refuse to vindicate
the enforcement action. It is the separate exercise of the distinct functions--the
executive’s decision to enforce, the judiciary’s decision whether to vindicate the
enforcement action--assigned to the departments that prevents the arbitrary law from
having effect on a citizen.
This version of thesis fares no better. Notice, first, that this version ignores
a large part of the universe of the enforcement of federal law. There are many ways
citizens’ rights and obligations are affected that do not involve the concurrence of
each department in the way the coordination thesis envisions--that is, passage of alaw, executive decision to enforce, and judicial adjudication of the enforcement
action. First, although there is controversy about and occasional judicial resistance
to preclusion of judicial review of agency action, Congress can and does preclude

Grundfest, Disimplying Private Rights of Action Under the Federal Securities Laws: The Commission’s
review of certain executive actions. In addition, there are a variety of common law,203
statutory, and constitutional doctrines that can operate to delay and sometimes
prevent judicial consideration of the legality of certain government actions; those
doctrines include finality, ripeness, exhaustion, and standing. In these examples, the204
courts are absent from a supposed three-branch coordination scheme. But it is not
just the courts that can be excluded; Congress too can be excluded from coordination.
The executive department controls the fates of large numbers of employees and its
decisions about whether to hire or fire those employees do not involve Congress. Nor
does Congress play a role in the exercise of prosecutorial discretion. The executive
decides how to enforce most statutes. And, on some understandings of the scope of
executive power, Congress could not constitutionally control the exercise of
prosecutorial discretion.205

is the absence of the executive when private individuals enforce federal law. Private206

these laws, private parties bring suit, and the judgments in those suits determine therights and duties of defendants. This phenomenon means that the executive
department is sometimes absent from the process of the enforcement of federal law.
The implication of this observation for the coordination thesis should be obvious. The
thesis misdescribes reality in a significant number of cases: where actions are brought
to enforce federal law, and it is not the executive bringing those actions, the executive
does not constitute a check on arbitrary legislative action. There is, to be sure, a
tangle of legal rules that govern when and how federal law can be privately enforced.
Those rules include: the doctrine, which has contracted, of implied private rights of
action ; the limitations on private enforcement that flow from sovereign immunity210

suits. Even so, these rules that sometimes limit private enforcement should not214
disguise the fact that enforcement of federal laws by private parties is stock-and-trade
of the federal courts. There is no controversy about these suits when the statute
expressly authorizes the suit, the plaintiff can point to a concrete injury and is not
purporting to proceed on behalf of the government, and the defendant is not a
government actor.
A realist critique of the coordination thesis would go even further. The
examples provided above include only the formal ways in which one department is
eliminated from three-branch coordination. But another critique would emphasize the
ways in which a single department, or two departments, can seriously injure an
individual where there is no meaningful review by another department, even if review
is formally available. For the best example, consider a prosecutor’s decision to indict
an individual. There is a serious injury to the individual at the moment of the
indictment itself; and this is so whether or not the individual is ultimately vindicated
in the prosecution. As just observed, Congress does not participate in a
“coordination” scheme with respect to prosecutorial discretion. As for court review
of the exercises of prosecutorial discretion, it theoretically exists, but that review is
under a standard so advantageous to the government as not to be any sort of real
review. Consider, also, challenges under the Equal Protection Clause to social and215
economic legislation, which is reviewed by the courts under the rational basis test.216
Again, the standard is so deferential to the legislature as not to be review at all.
217
This is not to say anything at all about the wisdom of these doctrines. It is only to say
that the coordination thesis is a misdescription of both the formal rules and the
meaning of those rules: it is simply not the case that each department of government
determines whether an action is arbitrary before an individual suffers the effect of that
action.

Draft 69
There is a still deeper problem with the coordination thesis. Consider thosecases where each department does have some formal role--the passage of legislation,
its enforcement, and the trying of that enforcement action in a court. The claim that
each department, in exercising its role, assesses the arbitrariness of the law implicated
in the case, may capture an arm-chair sense of how the system really works. But
there is something striking about this version of the coordination thesis: it departs
radically from the orthodox understanding of the three functions of government, as
well as the present legal rules arising out of that orthodox understanding. The thesis
suggests that one department will, through the use of its assigned function, second-
guess other departments on a constant basis. Arbitrary action is prevented, on this
view, because there are three entities that have to agree, independently of one
another, before an individual can be injured.
But the claim that each department does and should look independently at
every question that comes before it is wrong, both as a matter of theory and as a
matter of practice. This reading of the coordination thesis transforms routine
exercises of the executive and judicial function into feats of second-guessing, or
checking, the function that has come before in time. But the occasions for
interdepartmental checking are not that all-encompassing; they are, rather, sharply
limited--the exercise of the Presidential veto, judicial review (at least today), the
Senate’s confirmation powers, and Congress’ impeachment powers. Return to the
earlier example to see the point: assuming that the hypothesized “arbitrary” law thatCongress has enacted is a constitutional one, under the orthodox understanding of the
three functions of government, it is in fact Congress that is to make the policy
judgment. True, the executive enforces the law and the judiciary adjudicates disputes
under the law. But, except for the cases where the law is unconstitutional, it is not
the job of those exercising the executive or the judicial power to assess independently
the wisdom of the Congressional choice (and the Presidential choice, given that the
President either signed the bill, or suffered an override of his veto) reflected in the
statute. Far from it. Those exercising executive and judicial power are--except,
again, for the rare case of an unconstitutional law--to adhere to the policy judgment
made by Congress.
Another way of putting the point is that the coordination thesis rests on a
notion of governmental functions always and everywhere checking each other. On
this understanding, separating government functions collapses entirely into the
balance-of-power idea. But, the occasions for independent assessment by one

department of another are specific and circumscribed. The “checking” featureimplemented through devices like a Presidential veto or Congressional impeachment
is not supposed to be in play every time the executive decides whether and how to
enforce a law Congress has passed, or every time the courts decide whether to
vindicate a prosecution under a statute. To put the point simply: with respect to
statutes that are constitutional, Congress does reign supreme and it can and
(depending on one’s view) does enact arbitrary laws that are enforced by executive
officers and adjudicated by judges, and those actors are obliged to look to the statute
for their instructions.
Not only does the coordination thesis depart from the orthodox understanding
of the three functions of government, it also departs from the practice that arises out
of that understanding. Legal rules do not acknowledge an executive or judicial right
to assess independently the wisdom of a legislative choice. As students of law in a
post-realist period, of course, we know there is much room for discretion in the
execution of the law, and adjudication of disputes under the law. And, there do seem
to be little pockets of the coordination thesis. Consider in this regard the view--put
forward most prominently by Justice Scalia in his dissent in Morrison v. Olson --that218
the executive’s prosecutorial discretion emanates, not from pragmatic considerations,
but from the Constitution itself. On this view, Congress could not pass a statute219

http://slidepdf.com/reader/full/the-real-separation-in-separation-of-powers-law-ssrn 71/81
Draft 71
The view put forward by Justice Scalia and the Office of Legal Counsel goes far beyond the220
claim that the executive can refuse to enforce a statute that the executive deems to be unconstitutional.
There is a lively debate over the latter issue. See, e.g., Harrison, supra note ___, at 368-385
(constitutional text and structure suggest that executive must treat “as legal nullities acts of Congress
inconsistent with the Constitution” and, in determining whether acts violate the Constitution, executive
is not bound by congressional determination); Frank Easterbook, Presidential Review, 40 CASE W.
L.R EV. 905 (1990) (defending executive nonenforcement of laws the executive deems unconstitutional);
Christopher May, Presidential Defiance of “Unconstitutional” Laws: Revising the Royal Prerogative,
21 HASTINGS CONSTL. L.Q. 865 (1994) (arguing against executive nonenforcement).
The Scalia/Office of Legal Counsel claim about the scope of prosecutorial discretion is broader
than an assertion about nonenforcement in a context where enforcement would be, in the view of the
executive, unconstitutional. The broader view maintains that the executive has a constitutionally
protected right to enforce the statute however it sees fit (subject to narrow exceptions mandated by theConstitution), even if enforcement actions that the executive refuses to take would be, in the view of the
executive, constitutional enforcement actions. See supra note ___. Why the executive does, or should,
have this broader constitutionally protected power is not explained, it is just declared. It is worth noting
that, if one believes that the executive power includes the right to refuse to enforce a statute that the
executive finds to be unconstitutional, that may exhaust the constitutionally protected prosecutorial
discretion that Justice Scalia and others read into the term “executive power.”
restricting prosecutorial discretion, and this must be because executive power includes a constitutionally protected right to second-guess particular applications of
statutes in the course of enforcing them.220
Still, however appealing it might be to assert that the executive checks
legislative action when it decides whether and how to enforce a statute, and that a
court likewise checks legislative and executive action when it decides whether to
vindicate a prosecution, practice does not guarantee anything approximating that sort
of second-guessing. Barring a colorable constitutional claim about the statute or its
enforcement in a particular case, the executive (which, by definition, has either
consented to the law or had a veto overridden) would never claim it was not enforcing
a statute because the statute made the wrong choice; nor would a court claim its
interpretation had nothing to do with the statute approved by Congress. And
certainly no such understanding of the three functions would be cognizable in court
if a citizen tried to assert a claim based on the coordination thesis. Again reserving
the case of a colorable constitutional claim, a criminal defendant could not resist a
government prosecution by arguing that the executive had an obligation to decide for
itself--independently of the statute--the non-arbitrary choice in the circumstances of
the case; nor could a defendant argue that, in interpreting a statute, a court is free to
(or even obligated to) ignore the statute and decide the questions presented by the

Even if the coordination thesis does not comport with the orthodox
understanding of the functions of government, and does not map on to practice as
reflected in legal norms and rules, some might argue that the idea is normatively
appealing and, hence, the system should be reconfigured to reflect it. Putting aside
for the moment the normative merits of the thesis, it should not escape notice that
operationalizing this version of the coordination these would require a radical
alteration of present arrangements Consider a thoroughgoing coordination thesis
world: the statute is the first cut at the policy choice; the executive, in its decisions
about implementation and enforcement, and then the judiciary in its interpretation of
statutes, would each independently determine the correct, non-arbitrary, policy choice
in the circumstance. The executive has already consented to the statute (or its veto
has been overridden) and might be expected agree with the Congressional judgment
quite often, but no such prior consent would guide the judiciary’s interpretation. As
the example should show, adopting the coordination thesis would require re-making
the system from the ground up. Even if we could re-make the system, this
consideration should also raise questions about the normative attractiveness of the
thesis: as the example illustrates, it constitutes no less than a revision of the U.S. form
of legislative supremacy.
There is one final justification for institutionally separating functions that can
be called the rule of law thesis. This rationale for is best understood in the context221
of the command to institutionally separate lawmaking from law implementation: if the
same institution enacted and executed the laws, it could enact unreasonable laws and,
in its executive capacity, exempt itself from the application of that law; or, while
acting in its legislative capacity, the institution could exempt from operation of the
law the actions taken by the institution in its executive capacity. To state the idea222

explanation of the reasons for separation of functions, see Manning, supra note ___, at 645-648

in slightly different terms, this rule of law rationale is concerned with the conflict of interest presented when a single entity can both make the rules and apply them. It is
an idea that has been traditionally associated with separation of powers. And unlike223
the justifications just considered, this idea is tied to the need to allocate the functions
of government to different institutions and it does not threaten the U.S. form of
legislative supremacy.
THE FEDERALIST NO. 47, relying on Montesquieu, provides the rule of law
justification for the separation of legislative and executive power. There, Madison
writes:
The reasons on which Montesquieu grounds his [separation of powers] maxim
are a further demonstration of his meaning. `When the legislative and
executive powers are united in the same person or body,’ says he, `there can
be no liberty, because apprehensions may arise lest the same monarch or
senate should enact tyrannical laws to execute them in a tyrannical manner.’224
This is an oft-quoted idea--either directly from Montesquieu or from THE
FEDERALIST--but the only aspect of it that seems to have survived is that a
combination of functions threatens “liberty.” The reader is rarely told why that is
so. As this examination has demonstrated, however, the contention that a225
combination of government functions threatens liberty is open to many meanings. Itcould mean that liberty is threatened because there is a concentration of political
power; or it could mean that liberty is threatened because, once the functions are
joined together, the checking (or coordination) role that each function is supposed to

Perspectives, 20 CARDOZO L.R EV. 731-1018 (1999).
play is lost. But, as some historians have demonstrated, this passage, andMontesquieu himself, invoke the rule of law idea that warns against the concentration
of lawmaking and law implementation because of the conflict of interest presented by
that arrangement.226
Finally, then, we have isolated an independent justification for separating
government functions. That is, the rule of law explanation moves beyond generalized
support for dispersal of governmental power--an objective that does not require
functional separation--and it is a rationale, unlike the coordination thesis, that does
not challenge the U.S. version of legislative supremacy.
Once isolated in this way, however, the deficiencies of the rule of law idea are
obvious. Two are worth noting here. First, the idea depends on the ability to
distinguish among the functions of government in a workable and coherent way. On
the rule of law idea, it is crucial to separate lawmaking from law implementation; to
enforce that command, we would need robust definitions of lawmaking and law
implementation, definitions that would permit us to easily separate one from the other.
To state the task is to expose it as daunting, if not impossible. Two examples227
illustrate the depth of the difficulty. The status of the non-delegation doctrine
provides the first example. Judicial failure to enforce the rule that the legislature not
delegate lawmaking to other branches of government demonstrates that courts have
been unable to fashion a definition of lawmaking and law implementation that would permit them to sort the cases appropriately. It is not only, however, that it is228
difficult to tell the difference between lawmaking and law implementation. The point

See supra note ___.229
See, e.g, Dan M. Kahan, Is Chevron Relevant to Federal Criminal Law?, 110 HARV. L.R EV.230
469, 470 (1996) (“The orthodox defense of separation of powers rests on a profoundly mistaken
understanding of the nature of federal criminal law. The conventional account treats substantive criminallaw as exclusively legislative in origin; there are and can be no federal common law crimes. But this view
is impossible to sustain on close inspection. .. . . [F]ederal criminal law, as a whole, is best conceptualized
as a regime of delegated lawmaking”); cf. Kenneth C. Davis, POLICE DISCRETION (1975); Carl
McGowan, Rule-Making and the Police, 70 MICH. L.R EV. 569 (1972).
See TAN ___-___ (Part I.B.1.).231
may be deeper than that: it may be that a distinction between lawmaking and lawimplementation is incoherent. Consider an example that suggests as much:
enforcement of the law by prosecutors. Prosecutors’ ability to enforce the law in the
way they see fit is considered an executive function; indeed, it is thought to be
implementation of the law in the most basic sense. At the same time, decisions by229
prosecutors about how to enforce a statute are indistinguishable from lawmaking.230
That is, given that the range of permissible enforcement actions under criminal laws
(and many other laws) is extremely broad, it is the prosecutors’ pattern of decisions
that shape the meaning of the law, not the underlying statute itself. In such a context,
a command to separate lawmaking from law implementation seems incoherent.
There is another difficulty with the rule of law idea that relates to its salience.
It is difficult to ignore that the rule of law idea is a rationale that has been abandoned
as a constitutional constraint on the organization of government. That is, we
routinely countenance the combination of what appear to be all three functions of
government in a single entity. The acceptance of such entities may be explained by
the previous point about the difficulty, and perhaps incoherence, of distinguishing
among the three functions of government. Whatever the cause and however we might
ultimately define the three functions of government, in the regime we have adopted,
the combination of lawmaking, enforcement, and adjudication is routine.
Administrative agencies make the point most obviously: they are an example of
entities that combine lawmaking, law implementation, and adjudication under thelaw. This is not to assert that our acceptance of the combination of functions is the231
right outcome; it is only to say that it is the result our institutional practices reflect.
It is worth observing, however, that we have embraced a modified version of the rule
of law thesis: the Administrative Procedure Act requires some separation of functions

within an agency, and the Due Process Clause sometimes operates to require232
separation of functions within agencies. Neither of these doctrines, though, require233
that lawmaking, law implementation, and adjudication be separated on the institutional
level.
This examination of the reasons offered for separating functions underscores
the profound conceptual confusion caused by the muddle of the present consensus.
A variety of rationales are offered for separating functions. But some, like the
concentration of political power justification, do not actually require institutional
separation. And the coordination thesis is a common explanation, but, once
examined, it is open to devastating objections: it both misdescribes reality and defies
the U.S. system of legislative supremacy. Finally, the rule of law rationale, which
does map on to institutional separation while not challenging the U.S. form of
legislative supremacy, is all but lost in the muddle of the present consensus and it too
suffers from serious deficiencies.
3. Underdeveloped Ideas about Balance-of-Power
The balance-of-power conception is just as inadequate as the separation-of-
functions conception. And its limits are likewise traceable, at least in part, to
muddling the two conceptions together in the present consensus. That is so because
the unstated relationship between the two conceptions in the consensus--namely, thatseparated power (or functions) leads to balanced power --has heretofore supplied234
the explanation of just what this conception means. As already demonstrated,
however, the connections between the two ideas fail. It is tortured to treat functional
separation as a way of achieving tension and competition, and it is fanciful to treat
functional separation as a way of creating balance. Stripped of those explanations235
of the meaning of balance-of-power, the conception is virtually devoid of content.
We do not know what balance means, and we do not know how it is achieved or

maintained.
Consider first the meaning of “balance” in this conception. Its meaning is
indistinct. Its recondite character may be due to the ideas’ origin in the theory of
mixed government. That is, the meaning of balance may remain enigmatic because
of the difficulty of transitioning from, in the mixed government approach, a balance
of classes to, in the U.S. version, a balance of powers. Whatever the source of the236
opacity of balance, however, opacity it is: just how one might compare the power of
the executive, legislative, and judicial departments and pronounce them balanced is
absent from the balance-of-power conception.
Not only is the meaning of balance among the departments of government
unstated, the difficulties of supplying a meaning are formidable, if not insuperable.
Consider what would be needed if, when faced with an institutional arrangement, a
court wanted to determine whether the balance of power among the departments
would be upset by that arrangement. The standard supposes that the quantum of
power retained in one sphere of government could be measured. And not only must
a balance-of-power court measure the quantum of power retained in a single
institution, the court must comparatively measure that power--thus, institutions
exercising different types of power have to be compared to one another and the
balance of power among them must be discerned.
To measure power, we would have to start with a definition of power, power
in this precise context, governmental institutional power. One can suggest some237
ways to measure the quantum of power held by an institution; the trouble is, it is hard
to see whether any of those possible definitions capture what we might want to know.
One way of measuring power would be to determine whether one institution routinely
prevails over another institution; that is, has its interests vindicated consistently when
interests between the two are at odds. For instance, how often does Congress prevail
over the executive branch? We do have occasions where the two are directly pitted
against one another and perhaps the way to determine which has more power is to see
if one entity consistently prevails. But if we focus solely on those moments where

See TAN ___-___ (Part III.A.2.)238
there is an explicit conflict--say a veto by the President and an override of that vetoin the Congress--we will miss a large part of the picture. Much back and forth occurs
in the relationship between the executive and the legislative departments that does not
rise to the level of explicit, formal conflict, and yet, it could be said that the executive
or the legislature won: a rule promulgated that Congressmen, as a whole, did not
want, but their dislike was not sufficiently intense to rise to the level of formal
legislation to have it overturned; or, on the flip side, a proposed regulation scuttled
because a Congressional committee strongly objected and the administration was not
willing to fight to overcome opposition. If the executive wins hundreds of little
battles like that, does it still mean that one veto override by Congress on a question
of foreign aid means that the Congress has more power?
There is still another more vexing inquiry posed by the idea of balance
contained in the balance-of-power conception. Not only would we have to measure
the quantum of power held by each institution and compare it to the others, we would
have to identify a baseline of appropriate power allocation among the spheres of
government, and it is against that baseline that we would measure whether one sphere
of government had too much power. How would we identify our baseline of the
appropriate allocation of power among governmental institutions? Does that baseline
allocation remain static or fluid?
Perhaps, however, a balance-of-power court could put these questions asideand apply the conception in a different way. It may be that, as long as there is a
sufficient level of tension and competition among the departments of government, the
distribution of the power among those departments is as close to equilibrium as it
could be. Given the difficulties of defining, measuring, and comparing government
power sketched here, this is an attractive option.
Unfortunately, the balance-of-power conception, as presently developed, does
none of the work necessary to allow us to make that determination. The balance-of-
power conception does not identify what exactly creates and maintains competition
and tension. This gap may also be traceable to the uneasy transition from mixed
government to the modified U.S. form of balance; loyalty to social order is one thing,loyalty to functionally differentiated institutions is another. Once again, the muddle238
of the consensus has prevented us from seeing this deficiency. The consensus would

suggest that functional separation, by itself, is enough to create tension andcompetition. But, as demonstrated earlier, it is untenable to treat functional
separation as a way of achieving that tension and competition. Stripped of that way239
of creating tension and competition, the balance-of-power conception does not
identify the mechanisms by which tension and competition are created. Consequently,
a balance-of-power court would not know which arrangements would dilute that
tension and competition.
The balance-of-power conception, then, is underdeveloped. Once it is
detached from the separation-of-functions conception, it is revealed as almost
completely lacking in content. We do not know what balance means, nor do we know
what creates and maintains the institutional competition that is so important to the
conception.
IV. Beyond the Consensus
This Article has argued that the important divide in separation of powers
theory and doctrine is not the divide that has dominated the literature for decades: the
squabble over formalism and functionalism. That squabble has obscured a much more
pressing set of questions about the substantive theory of separation of powers. As
this Article has demonstrated, there is a surprisingly robust consensus about
separation of powers that is astonishingly underdeveloped. That consensussimultaneously embraces two distinct theories of separation of powers that cannot be
conceptually or doctrinally reconciled. The muddled consensus has had far-reaching
conceptual consequences: by glossing over the distinctiveness of the ideas contained
within the consensus, we have failed to see those two conceptions as independent of
one another and failed to think critically about each conception. The lesson of the
examination conducted here, then, is that the present consensus must be abandoned.
Abandoning the consensus is the first important step toward formulating a new set of
ideas about separation of powers.
What will follow from abandonment of the present consensus is not clear. It
may be that the two conceptions are irreconcilable and that we must choose betweenthem. Or it may be that they can be fit together in some as-yet-undeveloped way. Or
it may be that neither idea is sustainable and that we must reject them both. This final

path is the one Professor Bruce Ackerman urges in his provocative head-on challengeto the U.S. system of separation of powers in which he vigorously defends a modified
parliamentary system. This Article will not take up the latter steps on the road to240
a new consensus, but the effort here does clarify the challenges ahead for those who
resist alternative models--such as parliamentary government--and would develop a
new consensus out of the muddled and confused ideas now contained in the
consensus.
Those who wish to defend adherence to the separation-of-functions
conception face two evident difficulties. First, because the conception requires
institutional separation of government functions, it presupposes that we could identify
the attributes of each function and, in practice, enforce those lines. Defenders of this
conception, then, must start doing the hard work to provide those definitions. The
second challenge for those wishing to defend the separation-of-functions conception
is deeper: defenders of the conception must supply a satisfactory defense of
institutionally separating government functions. The examination conducted here
revealed that the one independent reason for institutionally separating functions--
namely, the rule of law idea--is a rationale that we have abandoned as a matter of
constitutional doctrine. Courts now permit the merger of lawmaking and law
implementation within administrative agencies. The rule of law ideal, to be sure, is
enforced in a modified way through the statutory and constitutional requirements that
require some separation of functions within agencies. But the challenge for those whowould adhere to separation-of-functions is to persuade others that these more limited
ways of enforcing the rule of law ideal are unsatisfactory.
The challenges for advocates of the balance-of-power conception are also
substantial. Defenders of this conception must do no less than provide content to the
conception where none now exists. Adherents must be able to articulate what is
meant by balance; they must provide some way of measuring and comparing the
quantum of power possessed by government institutions and, likewise, provide and
defend a benchmark against which to measure whether an arrangement would upset
that balance. Perhaps as a substitute to that seemingly impossible task, defenders of
this conception must identify how tension and competition among the departments arecreated and maintained. Only once that work is completed could courts be able to
assess whether an arrangement would dangerously dilute tension and competition.

The challenges for each conception are daunting. It may be that they are
insurmountable, in which case the conceptions must be modified or perhaps even
abandoned altogether. If the debate moves beyond incantations of the anthem that is
now the consensus--the brilliance and virtues of “separating power and balancing
power”-- and the tired references to Montesquieu and Madison, the effort conducted
here will have been worthwhile.
