IMPORTATION OF APPLES FROM NEW ZEALAND

Panel’s Second Substantive Meeting with the Parties:
Opening Statement of Australia
Geneva, 1 July 2009
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009

Introduction
1. Good afternoon Mr Chairman and members of the Panel. Australia welcomes the
opportunity to present this statement to you. Before we do so, we would like to acknowledge the
assistance provided by the experts. We would be grateful if you could please convey our
appreciation to the experts.
2. This presentation will be divided into four broad areas. Mr Burmester will deal with the
real world context in which risk assessments occur and the impact that this has on the legal
approach that the Panel must take to an analysis of the issues. Mr Jennings will then address
methodology and Dr Roberts will address fire blight. I will then deal with European canker and
apple leafcurling midge (ALCM), and will make some concluding comments. I will now hand
over to Mr Burmester.
3. Mr Chairman and members of the Panel, this case is about the conduct of risk
assessments in the “real world”, where:
. scientific data are rarely comprehensive;
. limited scientific data available cannot fully resolve uncertainty about elements of potential
pathways;
. expert judgment is a legitimate and necessary part of risk assessments; and
. risk assessors must use their expert judgment to interpret available scientific data and to
address uncertainty.

4. This is the real world in which WTO Members must base their SPS measures on
assessments, as appropriate to the circumstances, of the risks to human, animal or plant life or
health. And those assessments must themselves be based on scientific evidence.
5. In this context, you have to determine whether the three risk assessments before you in
the Final IRA Report are each objectively justifiable when taken in the context of Australia's
appropriate level of protection (ALOP).
6. To show that the risk assessments are not objectively justifiable, New Zealand must
establish serious flaws in the risk assessments for fire blight, European canker and ALCM. In
this statement, Australia will highlight why New Zealand has not done this and why its case
should be dismissed.
The practical realities of conducting risk assessments
7. We heard yesterday from Dr Schrader that lack of data is a problem with almost all plant
risk assessments, particularly where rare events are concerned. As a result, nearly every risk
assessment will involve expert judgment. Yet, faced with that reality, New Zealand seeks to take
a restrictive view of what should constitute sufficient scientific evidence. New Zealand, when it
suits it, does not accept that scientific evidence can be generated in a laboratory. It does not
accept risk pathways unless they have been historically documented and experimentally
confirmed in the orchard.
8. If New Zealand’s submissions were accepted, the scientific evidence used in risk
assessments would need to be absolute in its completeness and certainty; each step would need to
be supported by specific scientific evidence. New Zealand’s view not only fails to accord with
reality, as highlighted by discussions with the experts yesterday, but also runs contrary to the

guidance provided in previous WTO SPS cases.1 Indeed, Biosecurity New Zealand’s own Risk
Analysis Procedures recognise that such a possibility is “impractical” and that there is a “need to
achieve a balance between acquiring perfect knowledge and obtaining reasonable estimates upon
which we can base our predictions with a reasonable level of confidence.”
Sufficiency of scientific evidence is not equivalent to scientific certainty
9. The SPS Agreement itself allows for this balance through the concept of “sufficient
scientific evidence”. What will be “sufficient” scientific evidence for the imposition of measures
must be assessed according to the specific facts and circumstances of each pest, taking into
account Australia’s ALOP.
10. By asserting that scientific evidence will only be “sufficient” if facts are experimentally
proven under orchard conditions,2 New Zealand in substance argues that “sufficient scientific
evidence” means “scientific certainty”. However, as Australia has noted, full scientific certainty
does not exist. New Zealand also applies the term “sufficient” as a requirement that the
conclusions of a risk assessment conform with its view of the scientific evidence. However, this
interpretation runs contrary to the standard of a “rational relationship” which is established in
Appellate Body guidance and has been consistently applied in past SPS cases. New Zealand’s
narrow standard of “sufficient scientific evidence” has no basis in the text of the SPS Agreement,
and if adopted, would deprive Article 2.2 of all meaningful connection with scientific knowledge
as it is developed and applied in the real world.
1 See, for example: Panel Report, Japan – Apples, para. 8.98; Appellate Body Report, EC – Hormones,
para. 187.2 For example, see: New Zealand’s second written submission, paras. 2.111 – 2.121.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia

11. Australia agrees that the “conclusions drawn by the Member assessing the risk [must]
find sufficient support in the scientific evidence relied upon”.3 But certain steps in any given
pathway will be better supported by direct or experimental evidence than others. And there
could be many reasons for this, including that some steps are subject to greater levels of
investigation, while others may be very difficult to replicate experimentally to produce reliable
results. But, this fact alone cannot make the scientific evidence insufficient. The sufficiency of
scientific evidence relied upon by a Member is a judgment to be made in relation to the overall
risk assessment.
12. In the Final IRA Report, it is true that certain steps in the pathways assessed were better
supported by evidence than others. In those latter cases, expert judgment was employed. But
this does not affect the overall sufficiency of scientific evidence in the Final IRA Report, and the
Final IRA Report did not rely on 100% expert judgment.
Risk assessments may legitimately consider pathways that are not historically confirmed
13. Mr Chairman and Members of the Panel, in an effort to downplay the significance of the
risk, New Zealand devises an artificial distinction between a “hypothetical pathway” and a
“potential pathway”. However, New Zealand has focused on semantics – not substance. The
key issue is not how you label a pathway; it is whether the mere fact that it has not been
historically confirmed in every detail is a sufficient reason to dismiss a risk as pure speculation.
Australia does not consider that it is and the experts agree. Dr Paulin in particular recognised the
legitimate role of using hypotheses in conducting risk assessments.
14. It is common practice for many Members to impose SPS measures on fruit imports
despite there being no historically proven pathway for particular diseases. This is because
3 Appellate Body Report, US/Canada - Continued Suspension, para. 591.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
5
Members consider that, if fruit can be infected and carry the causal organism of a particular
disease, then it has the potential to introduce that disease to the importing country. In other
words, fruit is considered to be a potential pathway for the disease. Dr Schrader made precisely
this point yesterday.
15. In such circumstances, Members base their assessment on the biology of the disease. For
example, Australia understands that New Zealand has in place measures to protect against the
entry of certain pathogens on papaya and lychees,4 despite trade in these fruit not being a
historically proven pathway.
New Zealand is attempting to overturn Australia’s ALOP
16. Although New Zealand denies that it is judging what risks are significant for Australia, in
substance, it does precisely that when it argues that the standard of sufficient scientific evidence
contemplated by the SPS Agreement can only be met by conclusive, historical proof of a
pathway. Indeed, it notes that “the scientific evidence shows…that the likelihood that [the
pathway will be completed] is so small as to be insignificant”.5
17. But the judgment that the likelihood is “insignificant” is a value judgment about the
acceptable level of risk, not fact. This is exactly the kind of judgment which is not open to New
Zealand to make. The key issue is whether or not the risk is below Australia’s ALOP.
Standard of review and burden of proof remain fundamentally important
18. Mr Chairman and Members of the Panel, New Zealand has questioned Australia’s
motives in seeking to have the proper standard of review applied by the Panel. Australia has not,
4 Bipolaris hawaiensis, Pestalotiopsis sp. and Pytophthora capsici.5 For example, see: New Zealand’s second written submission, para. 2.454).
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009

as New Zealand claims, sought to “shelter” the Final IRA Report from review or to “divert the
Panel from the real issues in this case”.6 In fact, Australia’s position has been that the Panel
should begin its examination of this case by considering the Final IRA Report. And to facilitate
this examination, Australia has made its scientific and technical experts available for questioning
in all stages of these proceedings.
19. As Australia has made clear in its submissions, Australia recognises the legitimacy of
WTO scrutiny, but seeks to ensure that any review is consistent with the “delicate and carefully
negotiated balance” of rights and obligations contained in the SPS Agreement. Mr Chairman,
members of the Panel, you can review the Final IRA Report, but all that Australia asks is that
you apply the proper standard of review.
20. New Zealand’s only real contribution on the standard of review has been its objection to
Australia’s use of the term “considerable deference”. Again, by focusing on terminology, New
Zealand ignores the point that the substance of Australia’s submissions on standard of review has
been confirmed by the Appellate Body in US/Canada – Continued Suspension7. As previously
advised, in light of the detailed guidance provided by the Appellate Body since the first stage of
these proceedings, Australia no longer considers it necessary to use the term “considerable
deference”.8
21. The burden of proof on a complainant, which flows from the standard of review, requires
that New Zealand must establish serious flaws with the risk assessments at issue in order for the
Panel to be able to find that they are not objectively justifiable. Moreover, the objective
justifiability of a risk assessment is not impugned unless the complainant has demonstrated that
6 New Zealand’s second written submission, paras. 1.5 & 1.8.7 Australia’s rebuttal submission, paras. 13-18; US/Canada - Continued Suspension, paras. 590-615.8 Australia’s rebuttal submission, fn. 13.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
7
any serious flaws identified would have led to a lower level of assigned risk – not merely that
they might have done so.9
22. New Zealand has not proposed an alternative approach to determining whether a risk
assessment is objectively justifiable. Nor has it shown that any alleged flaws would have made a
difference to the overall conclusions of the risk assessments in the Final IRA Report.
23. Australia further recalls that New Zealand’s burden of proof means that it cannot rely on
either the Panel or the experts to make its case.10 It is up to New Zealand to raise arguments and
provide evidence in support of its claims. Furthermore, the Panel should be mindful that these
proceedings do not constitute some sort of “peer review” process, where the Panel is permitted to
rely on the experts to choose its preferred view of the science, because doing so would constitute
a de novo review of the Final IRA Report. As Australia has emphasised, multiple valid opinions
may result where there is a lack of data and therefore a degree of scientific uncertainty. This
point was exemplified by the experts’ sometimes differing responses to questions at the hearing.
The IRA is a legitimate scientific opinion
24. In inviting the Panel to make findings on the objective justifiability of the Final IRA
Report, it is clear that Australia does not consider that its risk assessments are self-justifying, or
that they are immune from review. WTO Members may legitimately rely on the scientific
opinions expressed in risk assessments as the basis of their SPS measures, if those risk
assessments are found valid. New Zealand makes the claim that the IRA "does not itself
constitute independent scientific opinion or scientific evidence".11 This is a surprising position
9 Appellate Body Report, Australia – Salmon (21.5), para. 7.57.10 See: Appellate Body Report, Japan – Agricultural Products II, para. 129.11 New Zealand’s opening statement at the first meeting, para. 49; New Zealand’s second written
submission, paras. 2.76, 2.107, 2.314.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
8
to maintain in the face of the repeated acceptance by both past WTO panels and the Appellate
Body that risk assessments unquestionably constitute scientific opinion.12
25. Thus, if Australia’s risk assessments are found valid, then Australia is entitled to rely
upon them as the basis of its measures, whether the conclusion on risk is a “divergent or minority
opinion” or not. In fact, Australia’s position from the very start13 has been that its SPS measures
stand or fall with the risk assessments in the Final IRA Report.
New Zealand seeks to revive its case
26. Mr Chairman and Members of the Panel, in response to Australia’s detailed explanation
in its first submission of the basis for the measures, New Zealand has attempted, in its rebuttal
submission, to revive its case by introducing new arguments which it had previously failed to
make. The Panel should not allow this to occur.
27. For example, New Zealand has used its rebuttal submission to attempt to expand its
claims under Article 5.6.14 New Zealand has sought to introduce further potential “alternative”
measures for the Panel’s consideration beyond its original argument that restricting imports to
“mature, symptomless apples” would achieve Australia’s ALOP for fire blight and European
canker.15 The introduction of such new claims should not be condoned by the Panel.
New Zealand explicitly restricted its claim to “mature symptomless apples”.16
12 See: Appellate Body Report, EC - Hormones, para. 194; Panel Report, EC - Biotech Products, paras.
7.3059-7.3060; US/Canada - Continued Suspension, para. 591. 13 See: Australia’s first written submission, para. 241.14 See: Australia’s rebuttal submission, paras. 448-452, 609-612; Australia’s responses to the Panel’s
questions after the first meeting, q. 138.15 See: New Zealand’s second written submission, paras. 2.894-2.895.16 New Zealand’s first written submission, paras. 4.490 & 4.491.

28. Even more glaring is New Zealand’s suggestion that it identified a “measure limiting
imports to retail-ready packaged fruit” in the context of its ALCM claim under Article 5.6.17
The reference made in its first written submission to such a potential measure under Article 5.6
was clearly only in relation to fire blight.18 The only “alternative” measure identified by
New Zealand for ALCM was a 600-unit inspection.19 Therefore, that is the only “alternative”
measure which the Panel may consider in respect of ALCM.
The role of experts is limited
29. Mr Chairman, members of the Panel, the experts have provided a wealth of information
during the course of this dispute, both in response to your written questions, and now, orally.
However, it is not just what the information consists of which is important, but how you now
choose to use it. In this regard, the Appellate Body in US/Canada – Continued Suspension has
provided guidance as to how panels may draw upon the assistance of experts in SPS disputes.
30. In particular, experts assisting the Panel have a very specific and very limited role, and
that is to provide advice to the Panel, to assist the Panel on the technical and scientific aspects of
this dispute. Panels may not defer judgment to experts on matters which ultimately require the
Panel to draw legal conclusions, such as what amounts to “sufficient scientific evidence”. Nor
may experts make the case for New Zealand.
31. Further, the experts’ views cannot be considered determinative of the issues in dispute,
especially where the question is not whether something can occur, but how likely it is to occur.
Australia accepts that the experts disagree with Australia on certain aspects of the Final IRA
Report, but equally, Australia considers that a rigorous review of any risk assessment will always

highlight particular points on which qualified and respected scientists disagree. The experts’
testimony is just one part of the evidence before the Panel, and simply because one or two
experts appointed by the Panel may disagree with particular aspects of a risk assessment, does
not mean that that risk assessment is not legitimate science. Nor is it for the Panel to choose
between different views.
32. In this dispute, seven experts from a field of potentially scores more have been selected
to assist the Panel in the four fields of expertise identified by the Panel. The practical reality is
that those seven experts may not be representative of the full spectrum of legitimate scientific
opinions held by their peers. Their views, those of the IRA Team and indeed, those of New
Zealand, may all sit on the same spectrum of legitimate scientific opinion.
New Zealand’s scientific claims fail to take into account the real world
33. Mr Chairman and members of the Panel, both parties in this dispute have set out lengthy
scientific and technical arguments on the risk assessments for the pests at issue in their written
submissions. Australia does not consider that it would be helpful, or in fact feasible, to rehearse
each and every one of these arguments in its oral statement today. Instead, Australia will focus
on certain key points to illustrate the superficial and selective, and ultimately flawed approach of
New Zealand to these complex issues. It fails to take account of the real world in which apple
production and trade occurs. Mr Jennings will begin this part of the presentation. Thank you.
Methodology
34. Mr Chairman and Members of the Panel, New Zealand asserts that there are three
fundamental flaws in the semi-quantitative methodology used in the Final IRA Report. These
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
11
assertions contain significant technical errors and lack evidentiary support. Simply put, New
Zealand fails to make its case on methodology.
35. Before addressing New Zealand’s assertions in detail, Australia wishes to note that, in the
meeting with the experts, Dr Sgrillo advised that the semi-quantitative model used in the Final
IRA Report was acceptable. He observed that the assessment of the likelihood of entry,
establishment and spread was conducted on a quantitative basis, while the evaluation of
consequences was conducted on a qualitative basis. As Australia has emphasised, the conduct
of an assessment on a quantitative basis means that the attention has to be paid to the probability
intervals used, rather than engaging, as New Zealand has done as part of its argument, in a
semantic discussion of the meaning of “negligible”.
New Zealand’s first claimed fundamental flaw
36. New Zealand argues that the probability intervals listed in Table 12 of the Final IRA
Report20 are “arbitrary” and that this is the source of the first fundamental flaw. In this regard,
New Zealand takes issue with the use of the interval 0-10-6, in particular, the maximum value of
10-6 or one in a million.
37. New Zealand asserts that this maximum value is “significantly greater than can be
justified on the basis of known data”, including trade data.21 It contends that the IRA Team
could have concluded on the basis of trade data that this maximum value was too high.22 In this
20 Final IRA Report, Part B, p. 43.21 New Zealand’s first written submission, p. 95.22 New Zealand’s first written submission, para. 4.182.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
12
regard, New Zealand points to its trade in apples, and that of the United States, with Chinese
Taipei. Australia has demonstrated that New Zealand’s reliance on its trade data is flawed.23
38. Australia recalls that, at the meeting with experts, Dr Paulin confirmed his answer to the
Panel’s question concerning New Zealand’s reliance on its trade with Chinese Taipei to support
its arguments on fire blight. Dr Paulin noted very significant differences between Chinese Taipei
and Australia as far the introduction of fire blight is concerned.24
39. Australia notes there is a fundamental contradiction in New Zealand’s case which is
starkly illustrated by its claim that trade data may support its case and yet the Final IRA Report
is to be judged strictly against experimental evidence under orchard conditions. Indeed, New
Zealand insists that the IRA Team should have used trade data to inform its expert judgment. In
New Zealand’s view, “the availability of real world trade data should have led the risk assessors
to apply a ‘most likely value’ to their probability distributions”.25
40. New Zealand asserts that, in terms of the volumes of apples that may be exported to
Australia, the chance of something occurring once in a million apples may not be seen to be
negligible.26 It states that, and I quote:
an adverse event with a probability of 1 x 10-6 on a per-apple basis is
equivalent to an expected occurrence of once in a million apples, or 150 timesper year, based on … Australia’s estimate of the most likely volume of apples
traded (that is, 150 million apples per annum).27
41. In making this calculation, New Zealand assumes that an adverse event with the
probability of once in a million apples will occur within the total population of 150 million
23 See Australia’s first written submission, paras 308-311; New Zealand’s second written submission,
paras. 247-263.24 Dr Paulin’s reply to q. 44.25 New Zealand’s responses to the Panel’s questions after the first meeting, q. 107, para. 236.26 New Zealand’s first written submission, para. 4.180.27 New Zealand’s second written submission, para. 2.342.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia

13
apples so that there would be 150 occurrences of the event every year. New Zealand states that
an event which occurs “150 times every year” is not an event that has a negligible likelihood of
occurring.28
42. However, New Zealand creates a misleading impression through its reference to an event
occurring “150 times every year”. New Zealand does not specify the nature of the adverse event,
where it occurs on a pathway, and whether that event would occur in the total population of 150
million apples. Australia asks the Panel to note that, without the specific case being given, New
Zealand’s calculation lacks any concrete connection to the Final IRA Report.
43. That this impression is misleading can be seen by reference to footnote 554 of New
Zealand’s second written submission, in which it states that, and I quote:
The median overall probability of entry, establishment and spread where a
small proportion of apples are handled through orchard based wholesalers is4.4 x 10-2 which equates to one instance … every 22 years. Based on the …
[importation of] 150 million apples per year, it can be ascertained that the IRA
assesses that 1 in every 3.3 billion apples will be contaminated with E .
amylovora and pass that contamination on to an uninfested host in a fire blightfree area with an infection occurring.
44. Unlike New Zealand’s failure to connect its calculation of 150 events per year with the
Final IRA Report, this footnote concerns the unrestricted risk assessment relating to the
probability of the entry, establishment and spread of fire blight. The relevant population in this
case is not the total volume of 150 million apples which may be imported into Australia, but the
subset of that population which will carry Erwinia amylovora, the organism which causes fire
blight. In relation to that population, Mr Chairman and Members of the Panel, one instance of
entry, establishment and spread of fire blight would be expected to occur every 22 years.
28 New Zealand’s second written submission, para. 2.342.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia

14
45. When New Zealand concerns itself with a specific case of a relevant population
associated with a pest or disease, the outcome stands in stark contrast to that obtained from its
abstract calculation of 150 events occurring per year based on the total population of 150 million
apples.
46. In this regard, Australia recalls that, in the meeting with the experts, Dr Sgrillo
acknowledged that, if only a proportion of a total population of apples was infested, then the
expected number of events would be reduced proportionately. Based on his example of applying
one in a million to 200 million apples, giving 200 events, Dr Sgrillo agreed that if the infested
population was only 1% of the total population, or two million apples, then the number of
expected events would be two.
New Zealand’s second claimed fundamental flaw
47. Australia now turns to New Zealand’s assertion that the second fundamental flaw in the
semi-quantitative methodology is the use of uniform distributions in the Final IRA Report.
48. New Zealand states that the more times that the @RISK model randomly samples from
a uniform distribution, the more the mean of the output will draw closer to the mean of that
distribution, that is the value which is half-way between the minimum and maximum values of
the distribution.29 New Zealand’s statement does describe how @RISK operates in this regard.
To New Zealand, this highlights the importance of setting the maximum value of a uniform
distribution because it influences where the mean of a uniform distribution will lie.
49. By way of example, New Zealand returns to the interval 0-10-6. New Zealand correctly
notes that the mean of this interval when applied as a uniform distribution is 5 x 10-7, or one in
29 New Zealand’s first written submission, para. 4.190.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
15
two million. New Zealand states that, if an adverse event has a probability of occurring once in
two million apples, then, in a population of 150 million imported apples, 75 occurrences would
occur.30 Again, without the specific case being given, New Zealand’s calculation is in the
abstract and lacks any concrete connection to the Final IRA Report.
50. In its second written submission, New Zealand also asserts that there was “no evidence,
presented anywhere” that there was a “structured or recognised” process in place for eliciting the
opinions of IRA Team members and that this resulted in a “mechanistic approach” that produced
“frequent and unexplained” applications of uniform distributions.31 New Zealand’s glaring error
in making this assertion was highlighted in the meeting with experts yesterday when Australia
referred the Panel and New Zealand to Appendix 1 of the Final IRA Report.
51. Australia recalls that in Appendix 1 there is a summary of key points of the elicitation
process, which involved multiple discussions between the Bureau of Rural Sciences and the IRA
Team. As Australia noted in the meeting with the experts, Dr Barry was closely involved in
those discussions and would be happy to elaborate upon them to assist the Panel.
52. To conclude on this issue, Australia submits that uniform distributions may be
appropriately used in circumstances where the available evidence only allows the risk assessor to
estimate a minimum and maximum value, but not a most likely value for an interval. Dr
Schrader has identified this as a circumstance in which a uniform distribution can be used, as
does Firko and Podleckis (2000).
New Zealand’s third claimed fundamental flaw
30 New Zealand’s first written submission, para. 4.191.31 New Zealand’s second written submission, para. 2.348.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
16
53. Australia will now address New Zealand’s assertion that the third fundamental flaw in the
use of a semi-quantitative methodology is that it overestimates the likely volume of trade in
apples from New Zealand. This assertion is based on faulty suppositions.
54. The first is that New Zealand wrongly supposes that Australian consumers will not buy
the main varieties of apples it produces, such as Royal Gala and Braeburn. New Zealand
contends that the low production of Braeburn in Australia indicates it is not favoured by
Australian consumers. In its second written submission, Australia provides evidence that the low
production of the Braeburn variety in Australia is not due to consumer preference, but to the
difficulties associated with growing that variety.32
55. The second is that Australian supermarkets will be unlikely to stock New Zealand apples.
In its second written submission, New Zealand states that Australia has not challenged its
submissions regarding the position of Australian supermarkets. But Australia has done so in
both its first and second written submissions, demonstrating the lack of substance in New
Zealand’s assertions.33
56. The third is that the volume of New Zealand apples entering the Australian market would
lead to large price falls, making its exports uneconomic. In this regard, New Zealand seeks to
rely on an analysis prepared by the Australian Bureau of Agricultural and Resource Economics
(ABARE) that was taken into account in the Final IRA Report. Australia has demonstrated that
New Zealand’s assertions in relation to the ABARE analysis lack substance. As to the economic
viability of New Zealand apple exports, Australia recalls the views of advisors to the New
Zealand apple industry that Australia represents a significant export opportunity.
32 Exhibit AUS-126: Tancred (2009).33 See Australia’s first written submission, paras 331-333, and Australia’s second written submission, paras
284-289.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
17
57. The fourth is that New Zealand’s apple exporters will not divert apples to the Australian
market. Australia has exhibited material showing that a range of factors, such as increased
competition in New Zealand’s markets in the Northern Hemisphere, are placing significant
pressure on New Zealand exporters. In these circumstances, Australia would be a significant
new market.
58. In sum, New Zealand’s assertions concerning the semi-quantitative methodology in the
Final IRA Report lack substance and should be rejected by the Panel.
59. I will now hand over to Dr Roberts.
Fire blight
The fire blight case is essentially about the acceptable level of scientific uncertainty in risk
assessments
60. Mr Chairman and Members of the Panel, I now turn to address fire blight.
61. Countries with a very low tolerance for risk – such as Australia – face a difficult
challenge in performing risk assessments on the basis of available evidence in cases where rare
events have serious consequences. In such cases, an appropriate balance must be found between
a Member’s sovereign right to protect against rare events with serious consequences, and the
level of scientific evidence sufficient to justify the taking of measures.
62. Mr Chairman and members of the Panel, there is little doubt that fire blight is one of the
most serious and destructive plant diseases in the world. For this reason, it is also one of the
most studied diseases in the plant world. Yet despite the efforts of the scientific community,
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
18
some issues on fire blight remain unresolved and those uncertainties lie at the heart of this
dispute.
63. The case for fire blight essentially comes down to the degree of scientific uncertainty that
the SPS Agreement can tolerate in a risk assessment. What is acceptable will depend on how the
elements of uncertainty – that is, what we do not know, and perhaps cannot prove about fire
blight – measure up against what we do know and have proven about fire blight. Importantly, it
is up to New Zealand to show that the element of uncertainty results in a flaw so serious that, if
absent, it would have – not might have, or could have – led to a lower level of overall assessed
risk.34 In practical terms, this means that the overall level of risk must be shown to drop below
Australia’s ALOP. Then, and only then, should the Panel find that uncertainty has compromised
the fire blight risk assessment to such an extent that it cannot have reasonable confidence in the
evaluation made.
64. In this regard, one of the most significant outcomes of yesterday’s meeting was that fire
blight experts not only confirmed that there is a potential pathway for fire blight through mature
apples,35 but that there is a real risk present to be assessed and managed. Dr Paulin again
explicitly supported Australia’s two principal risk reduction measures, which clearly indicates
that the risk associated with that pathway is above Australia’s ALOP. Australia considers that
there can be no better endorsement of the ultimate conclusion reached in the fire blight risk
assessment. As such, any flaws in the Final IRA Report cannot be regarded as compromising the
overall conclusion that fire blight measures are required for New Zealand apples, and the Panel
should have reasonable confidence in the evaluation made.

65. New Zealand’s burden of proof is central to the fire blight case. This is not a diversion,
or a legal argument designed to distract you from the scientific evidence. This case is about the
scientific evidence and that includes whether New Zealand’s evidence, in light of what you have
heard yesterday, has satisfied you that the rare events which Australia seeks to protect against are
not supported by scientific evidence.36 It is not about what risks are most probable, not about
what risks are associated with small volumes of apples and not about what risks other WTO
Members consider significant. Australia has explained that its fire blight risk assessment is
concerned with a specific risk scenario,37 and yet it is this scenario which New Zealand has
consistently ignored. In doing so, New Zealand has failed to discharge its burden of proof in
relation to fire blight.
New Zealand’s “pathway” argument is the core of its fire blight case.
66. Mr Chairman and members of the Panel, the central pillar of New Zealand’s argument is
the claim that there is no scientific evidence supporting a pathway for fire blight through mature
apples.38 New Zealand has put forward several variations of this argument – that the pathway
does not exist,39 that it does not exist for practical purposes,40 that it is “insignificant”,41 that it
has not been shown to occur, and that it will never occur in the future.42
36 New Zealand’s central argument, as is discussed later, is that there is no pathway for fire blight through
mature apples.37 Australia’s rebuttal submission, paras. 322-324.38 See for example: New Zealand’s second written submission, paras. 2.104, 2.108, 2.110, 2.111, 2.120,

Neither the SPS Agreement or ISPMs require risk assessments to be based on historically
“proven” pathways
67. Turning first to the claim that the pathway does not exist, New Zealand asserts that
“Australia’s fire blight measures would be justified only if there were scientific evidence to
support the overall pathway”;43 that is, “evidence supporting the linking together of the steps as a
complete pathway”.44 In effect, New Zealand claims that risks do not exist unless the pathway
has been historically documented and experimentally proven.
68. However, this requirement has no basis in the SPS Agreement or the international
standards45. Dr Schrader confirmed this point in yesterday’s meeting and in her written
responses to Question 45. As Dr Schrader is an expert on ISPM No. 2 and risk assessment
methodologies, Australia considers that her views should be given weight by the Panel.
69. Similarly, Articles 5.1 and 2.2 do not refer to pathways and do not impose any
requirement that Members assess only the pathways that have been historically documented.
New Zealand may assert that Japan – Apples is authority for the claim that the SPS Agreement
requires pathways to be “actual pathways, not merely hypothetical ones”.46 However, New
Zealand is silent on which part of the panel report supposedly supports this view. To read such a
requirement into either provision is tantamount to requiring full scientific certainty in relation to
every risk.

70. However, as the fire blight experts have told us yesterday, the pathway for fire blight is a
long way from being wholly “speculative”. This is a pathway that is substantially confirmed
with some elements of uncertainty.
The fire blight pathway is substantially confirmed
71. Mr Chairman and Members of the Panel, you should not lose sight of this fact. While the
pathway for fire blight through mature apples as a whole may not be confirmed by direct
experimental evidence as New Zealand claims it should, a very substantial part of the pathway is
confirmed.
72. It is beyond doubt that live E. amylovora, the causal organism for fire blight, will enter
Australia on the surface of mature apples if trade occurs.47 It is beyond doubt, and undisputed by
New Zealand, that Australia has suitable conditions for the establishment of fire blight disease.48
It is also beyond doubt, that if fire blight were to establish in Australia, there is the potential for
spread within geographic regions.49 Finally, it is beyond doubt that fire blight, one of the most
serious plant diseases in the world, has the potential to cause severe economic and biological
loss.
73. Only one step in the pathway is subject to any real degree of uncertainty, and that is
whether E. amylovora can be transmitted from an apple to a susceptible host plant, and initiate a
fire blight infection. But even in relation to this point, there is indirect evidence that
transmission can occur. Dr Paulin confirmed yesterday that rotting apples discarded in an
47 CABI. Indeed, the vast preponderance of scientific evidence accept that E. amylovora will be found on
the surface of apple fruit when sourced from areas where fire blight is endemic.48 Australia’s first written submission, para. 482.49 Australia’s first written submission, para. 485.

orchard can provide a possible source of inoculum.50 The experts also confirmed that the
relevant transmission mechanism contemplated by the IRA Team – that is, pollinating insects –
is a confirmed mechanism for the secondary spread of fire blight and that primary spread could
occur in the way described by the IRA Team.51 Finally, the IRA Team’s view that small
numbers of bacteria (around 10 colony forming units (cfu)) can multiply to cause infections in
susceptible hosts is supported by scientific evidence. It is true that some of this evidence is
uncertain. But as Dr Schrader said, uncertain evidence is quite different to no evidence, and it is
often the only evidence risk assessors have.52
74. When taken together, the IRA Team’s judgment that transmission could occur in a rare
case can hardly be dismissed as “speculation”.53 The available evidence on this point may not
support direct proof, but it does support a rational inference that the pathway can be completed.
Australia is not alone in taking this view. Australia’s view is corroborated in the phytosanitary
practices of other WTO Members who impose very similar risk management measures to
Australia.54
New Zealand’s evidence does not support the claim that the pathway will not be completed in
Australia’s circumstances.
75. Mr Chairman and Members of the Panel, however, even leaving these issues to one side,
New Zealand cannot simply assert that the pathway is “hypothetical”. It must prove this point
with evidence and argument.

76. New Zealand’s pathway argument, and indeed its fire blight case, rests primarily on three
pieces of evidence. These are: Japan – Apples, Roberts and Sawyer (2008) and “real world”
trade data. It is highly significant that each of these three bases have either been discredited by
Australia,55 rejected by the experts as irrelevant or inappropriate,56 or both. Recently, New
Zealand has asserted that several other studies, namely Roberts et al. (1998), Hale et al. (1996),
Taylor et al. (2003a) and Taylor et al. (2003b) also point to a lack of a pathway. However, New
Zealand fails to acknowledge that much of this evidence57 cannot be relied on for drawing
conclusions about the risk in Australia’s circumstances.
77. Dr Paulin and Dr Deckers confirmed yesterday that it is not possible to draw conclusions
about rare events from Hale et al. (1996) and Taylor et al. (2003a) as the sample sizes are not
comparable to commercial volumes of international trade in apples.
78. The data set in Roberts et al. (1998) was the same data set used by the later Roberts and
Sawyer (2008), and accordingly, suffers from the same defects identified by Australia in Annex
1 of its rebuttal submission. The key problem is that while the Roberts papers may indicate
something about the efficacy of phytosanitary measures, it is not possible to draw reliable
conclusions about potential risks when trade is unrestricted.58
79. Finally, apart from the two Roberts papers, it is highly significant that the majority of the
scientific evidence that New Zealand relies upon has not found that the pathway does not exist.
They have all found, including Japan – Apples, that the pathway is “negligible”. This is an
55 In relation to Japan – Apples, see: Australia’s first written submission, paras. 250-262; Australia’s
responses to the Panel’s questions after the first meeting, q. 40; Australia’s rebuttal submission, paras. 325-329. In

24
important point: a likelihood of “negligible” is not zero, nor does it mean that an event will not
occur, unless you apply a definition of “negligible” that means “insignificant” or “not worth
considering”. This is where, contrary to its denials, New Zealand has trespassed on Australia’s
sovereign right to determine ALOP.59 The significance or otherwise of a potential event is
ultimately a value judgment and therefore, a judgment for Australia alone.60 Since Australia is
concerned with rare events, non-zero findings are significant.
New Zealand has not demonstrated serious flaws in the Final IRA Report
80. Mr Chairman and Members of the Panel, once New Zealand’s pathway argument falls
away, the only remaining question is whether New Zealand has established serious flaws in the
Final IRA Report. New Zealand has consistently failed to show any serious flaws in the levels
of probability assigned to key steps in the pathway, and consequently, has not overturned the
overall conclusion that the risk is above Australia’s ALOP. The defects in New Zealand’s
arguments on the various steps in the pathway are discussed in detail in Australia’s rebuttal
submission and Australia will not rehearse them all here. Australia will refer to a number of
further issues that the Panel should consider when testing New Zealand’s claims.
81. In relation to Importation step 1, New Zealand asserts that the probability of 1 is
overestimated since E. amylovora cannot be present in all source orchards in New Zealand.61
This implies that the IRA Team should have taken into account that an undefined number of
potential export orchards have area freedom and factored this into their assessment.
82. However, under Article 6 of the SPS Agreement, it is up to exporting Members to
“objectively demonstrate” disease free areas and areas of low pest prevalence. A good example
59 See: New Zealand’s second written submission, paras. 320 & 321.60 See: European Communities’ third party submission, para. 33.61 New Zealand’s second written submission, para. 2.402.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
25
of this is Japan’s demonstration of area freedom in Tottori in relation to brown rot and Japanese
Erwinia. In the case of orchard freedom from E. amylovora, it would be very surprising if a
lesser standard of objective proof regarding the application and efficacy of measures would
apply in the risk assessment context under Article 5.1. In this case, New Zealand had many
opportunities to provide the relevant evidence to the IRA Team but declined to do so despite
repeated requests.62 It is therefore not credible for New Zealand to effectively argue that it has a
claim to area freedom when it clearly does not.
83. A similar problem arises in respect of New Zealand’s claims under Importation step 4.63
New Zealand claims that “disinfection of fruit as a routine procedure …occurs in New Zealand
packing houses and therefore…has to be considered in the assessment of unrestricted risk.”64
But again, this implies that the IRA Team should have assumed that that an undefined number of
packing houses achieve equivalence to Australia’s disinfection measure.
84. Article 4.1 of the SPS Agreement states that Members need only accept other measures as
equivalent “if the exporting Member objectively demonstrates to the importing Member that its
measures achieve the importing Member’s ALOP”. New Zealand has certainly provided
evidence that some disinfectant is used in some packing houses, but no “objective” proof as to
whether disinfectant is applied effectively.65 Accordingly, New Zealand has no legitimate claim
of equivalence, and the IRA Team could not have been expected to make such an assumption in
its unrestricted risk assessment.
85. As New Zealand correctly points out in Annex 1 of its second written submission, the
three key importation steps which make the most significant contribution to the probability of
62 Final IRA Report, Part B, p. 54.63 New Zealand’s comments on Australia’s comments on the experts’ replies, paras. 45 & 46.64 New Zealand’s comments on Australia’s comments on the experts’ replies, para. 46.65 Australia’s rebuttal submission, para. 382.

26
entry are Importation steps 2, 3 and 5. However, New Zealand’s arguments on Importation step
2 are simply not credible in light of its failure to acknowledge the critical assumptions
underpinning the analysis66 and its insistence that endophytic infection is relevant to the IRA
Team’s assessment in the face of clear and explicit statements to the contrary.67
86. In relation to Importation steps 3 and 5, the Panel should bear firmly in mind that New
Zealand led no substantive evidence and argument of its own in the first stages of this dispute.
Realising the significance of these steps to the overall risk, it has retrospectively sought to use
the experts’ replies to advance a case it failed to make previously. This is not consistent with the
principle that the complainant bears the burden of proof in this dispute, and the Panel should take
care that it does not inadvertently make the case for New Zealand by allowing the experts’
replies to plug the significant gaps in New Zealand’s evidence.68
87. Mr Chairman and Members of the Panel, but even leaving the legal concerns aside, the
experts’ replies do not raise an inference of serious flaws. It may be superficially convincing
that New Zealand can point to potential problems in the Final IRA Report by asking the experts
to confirm some doubts about some of the IRA Team’s evidence. But this shows nothing more
than the fact that the experts did not agree with the IRA Team’s analysis in its entirety. For
when Australia asked the experts yesterday whether the key steps underpinning the IRA Team’s
analysis were based on science, they unanimously said “yes”. This affirmation is simply not
compatible with any assertion that Australia’s risk assessment lacks foundation.
88. No risk assessment conducted in the real world can be free of problems, and it is simply
not enough for New Zealand to point to minor flaws and assume that they have the kind of

27
impact on the overall risk that New Zealand hopes for. New Zealand has to prove that the
absence of any shortcomings would have led to a lower level of assessed risk, and in this it has
failed. It has not shown that a reduction in the likelihoods assigned to Importation steps 2, 3 and
5 will result in the reduction in the overall risk such that it drops below Australia’s ALOP. I will
now hand over to Mr Baxter. Thank you.
European canker
89. Mr Chairman and members of the Panel, I would now like to turn to New Zealand’s
challenge to the IRA Team’s risk assessment for European canker.
90. At the outset, Australia recalls that at yesterday’s meeting with the experts,
Professor Latorre reiterated his view that there is a risk of introducing Neonectria galligena
associated with the importation of latently infected apple fruit.69 Moreover, both experts agreed
that the long distance spread of European canker via apple fruit could not be ruled out.70
Australia’s climatic conditions
91. One of the common threads running through New Zealand’s case on European canker is
the alleged unsuitability of Australia’s climatic conditions for the development of the disease.
However, as Australia elaborated at yesterday’s experts meeting, there are areas of Australia,
including commercial apple growing regions, which have climatic conditions suitable for the
establishment and spread of European canker.71
69 Reply of Prof Latorre, Guideline (g) and q. 65.70 Reply of Prof Swinburne, q. 64.71 Australia’s rebuttal submission, paras. 532-550.
Australia – Apples (DS367) Second Meeting: Opening Statement of Australia
1 July 2009
28
92. Contrary to what New Zealand asserts,72 the Final IRA Report contains an objective,
coherent and substantive analysis of the environmental conditions, including climate, relevant to
the establishment and spread of European canker.73 The validity of this analysis has been
confirmed by the detailed work undertaken by the Bureau of Rural Sciences (BRS).74
93. Rather than identifying any serious flaws in the IRA Team’s consideration of climate,
New Zealand has simply introduced an alternative climate analysis in an attempt to impose its
view of the science on Australia. This is a prime example of the underlying premise of New
Zealand’s case, namely that there is only one “correct” view of the science. In adopting such an
approach, New Zealand attempts to reverse the burden of proof in this dispute, arguing that
Australia has failed to demonstrate any errors in New Zealand’s climate analysis.75
94. What New Zealand fails to recognise is that, just because there may be alternative views
as to the climatic conditions conducive to European canker, this does not mean that the IRA
Team’s analysis is invalid. This is particularly so given the ongoing debate in the scientific
community regarding the climatic conditions required for European canker development
resulting in a variety of predictive models.76 In this regard, Australia notes Dr Swinburne’s
comments yesterday confirming that there is no complete model to assess the climatic conditions
required for the development of the disease. He also mentioned that there are a range models
around the world which are yet to be joined up and that this is a complicated area necessitating
expert judgement.

Australia – Apples (DS367) Second Meeting: Opening Statement of Australia

95. The BRS climate analysis draws on a range of these predictive models to demonstrate the
climatic similarity between parts of Australia and those areas of the world where European
canker is present.77 The BRS analysis shows that, if European canker entered Australia, it could
establish and spread to host plants in Australia’s commercial apple growing regions and
metropolitan areas, such as Sydney and Melbourne. Both European canker experts accepted this
at yesterday’s meeting. In fact, even New Zealand acknowledges that parts of Western
Australian and Tasmania, which include some of Australia’s major apple growing regions, have
suitable climates for European canker.78
96. To drive home this point, Mr Chairman and members of the Panel, Australia considers it
worth highlighting that the BRS climate analysis employed New Zealand’s own Beresford and
Kim model. In doing so BRS demonstrated that Melbourne, Sydney and one of Australia’s
major apple-growing regions in South Australia, all had months meeting Beresford and Kim’s
requirements during autumn, the most suitable period for infection.79 New Zealand has
completely failed to respond to this aspect of the BRS climate analysis.
97. Mr Chairman and members of the Panel, the alleged unsuitability of Australia’s climate
lies at the core of New Zealand’s case on European canker. It underpins New Zealand’s
arguments: on spore production, dispersal and infection;80 on establishment and spread;81 on
alternative hosts;82 on the Spreyton disease outbreak;83 and on consequences.84 Therefore, once

30
you accept the reality that New Zealand does not have the only legitimate predictive model for
European canker development, its case falls away.
Importation step 2
98. Mr Chairman and members of the Panel, another criticism which New Zealand makes of
the Final IRA Report relates to the incidence of latent fruit infection in New Zealand which, as
you will recall, is the focus of the IRA Team’s analysis under Importation step 2. New Zealand
continues to equivocate on this matter.85 However, the reality is that fruit rot occurrences have
been reported in New Zealand and it follows that latent fruit infection does occasionally occur in
New Zealand.86 This was the view of the IRA Team87 and it was accepted by Dr Swinburne at
yesterday’s meeting.
99. In arriving at its conclusion on Importation step 2 the IRA Team took into account an
observation of latent fruit infection in New Zealand by a specialist field plant pathologist.88 This
observation was contained in an official report of the New Zealand Ministry of Agriculture and
Fisheries, a report New Zealand now seeks to disown in the context of this dispute.89
Proximity and exposure
100. Mr Chairman and members of the Panel, New Zealand also seeks to question the IRA
Team’s analysis of proximity and exposure for European canker.90 However, the IRA Team’s
view that discarded infected apples can produce spores, primarily conidia, which disperse and
85 New Zealand’s second written submission, para. 2.129, 2.143, 2.149, 2.150, 2.460 & 2.488.86 Australia’s rebuttal submission, paras. 473-485.87 Final IRA Report, Part B, p. 123.88 Personal communication from Mike Dance: Exhibit NZ-34: Braithwaite (1996), p. 5.89 New Zealand’s second written submission, paras. 2.138-2.147; 2.152-2.156 & 2.486-2.487.90 New Zealand’s second written submission, paras. 2.574- 2.635.

31
initiate infection, is legitimate science.91 This view is consistent with the biology of fungal
pathogens as evidenced by photographic evidence showing masses of conidia on rotten fruit.92
101. In addition, Australia recalls that Professor Latorre yesterday reiterated his view that:
asymptomatic but infected mature apples could develop symptoms and eventually sporulate
during transit and commercialisation in Australia;93 and also that rotted fruits discarded near
susceptible hosts could potentially be a source of inoculum for infections in new areas.94 During
the experts meeting, Dr Swinburne also suggested that some latently infected New Zealand
apples arriving in Australia could develop spores.
Consequences
102. Mr Chairman and members of the Panel, New Zealand’s criticism of the IRA Team’s
consequences analysis completely disregards Australia’s ALOP and the fact that it is free of
European canker.
103. At yesterday’s experts meeting, Professor Latorre confirmed that plant pathology
information from around the world95 – which informed the IRA Team’s consideration of this
matter – invariably refers to European canker as being a severe disease with serious
consequences. Dr Swinburne confirmed that European canker can be very damaging.
104. Yesterday Dr Swinburne also noted the occurrence of 5% European canker fruit rot at
East Malling in the United Kingdom,96 an area which he confirmed only had marginal climatic
suitability for development of the disease. Australia cannot accept that such an event could be

considered as anything less than “moderate” – and that is the consequences rating assigned to
European canker by the IRA Team. This is especially so given Australia’s particular
circumstances, including the fact that there are a wide range of alternative hosts plants in
Australia.97
105. In sum, Mr Chairman and Members of the panel, although there is a low risk associated
with importing New Zealand apples, this risk exceeds Australia’s ALOP. Accordingly, the IRA
Team determined that it was necessary to source apples from New Zealand export orchards or
blocks free of the disease. Professor Latorre reiterated yesterday that in his view this is a
reasonable risk mitigation measure.98 Moreover, both experts agreed that an SPS measure
requiring New Zealand to export mature symptomless apples would not achieve Australia’s
ALOP.
ALCM
106. Turning now to ALCM, at the outset, Australia takes this opportunity to correct the
suggestion in New Zealand’s rebuttal submission that a 3000-unit inspection would be
undertaken by Australian officials99 in addition to the 3000-unit inspection required to be
undertaken by New Zealand. Australia requires only a single 3000-unit inspection per
consignment (rather than per orchard100) to be conducted under the auspices of New Zealand.101
107. Mr Chairman and members of the Panel, your consideration of the ALCM risk
assessment needs to be cognisant of the significant lack of data available on several of the key

inspection would apply to apples from each orchard.101 See: Final IRA Report, Part B, pp. 319-320.

issues in dispute – including the viability of ALCM on New Zealand apples, the time required
for adults to emerge following cold storage and also flight distance. ALCM is present in only a
few countries, and as Professor Cross confirmed yesterday, there has been relatively little
research conducted or reliable data generated on this pest. This point is illustrated by the
difficulty the Panel had in identifying an ALCM expert for the purposes of this dispute.
108. During these proceedings, New Zealand has provided new data on a number of issues in
its attempt to criticise the IRA Team’s evaluation of ALCM.102 Obviously, however, the
IRA Team could not have considered information that was not available to it during the IRA
process. Australia recognises that this new information would need to be taken into account in
any review of the import conditions; such a review mechanism is indeed provided for in the
Final IRA Report itself.103 But it is clear that still further reliable data is required, and as
Professor Cross indicated, New Zealand is in the best position to provide the appropriate
information.
109. New Zealand does not seriously dispute that ALCM could establish in Australia from a
biological perspective. Professor Cross’ reference to the “powerful life force” in the context of
the insect’s potential survival in a new environment was significant in this regard. Rather, New
Zealand relies on its assertion that the “majority” of its exports will be in the “retail ready” form,
which New Zealand contends means that insufficient numbers of infested apples would come
within proximity of suitable hosts. And secondly, that “Australian agricultural waste practices
would preclude any opportunity for ALCM establishment” because of New Zealand’s conjecture
that apple waste is never left exposed in Australia.104 Both its assertions are flawed.

110. Professor Cross’ opinion that the level of risk associated with ALCM might be lower
than that evaluated by the IRA Team was clearly conditional on whether New Zealand apples
would not be distributed to orchard wholesalers and would be continuously held in cool chain
conditions until point of sale.105 In Australia’s view, New Zealand has failed to establish the
validity of either of these propositions. Professor Cross confirmed that if large volumes of
apples were directed to orchard packing houses, the risks would be much greater.
111. New Zealand has not established that the “majority” of its apples would be imported
“retail ready”. Australia has set out the reasons why this would be determined by commercial
factors. And even if the “majority” of apples were imported retail ready, New Zealand has not
demonstrated that such apples would never be sent to orchard wholesalers for repackaging or
reconditioning.106 Similarly, New Zealand has failed to establish that apple waste would be
managed in the way that it asserts, and that groups of apples would never be left out of cold
storage near host plants for a sufficient length of time.107
112. New Zealand has also failed to address Australia’s argument that waste from orchard
packing houses is not the only relevant risk scenario.108 Professor Cross agreed with Australia’s
point in this regard, and observed that ALCM could remain dormant in the soil in Australia until
environmental conditions became suitable for emergence.
113. Neither Australia nor New Zealand is in a position to specify with any degree of
precision how frequently the mode of trade would be via bulk fruit as opposed to packed “retail
ready” fruit. It will depend on commercial considerations which will vary according to the
105 Professor Cross stated: “If all fruit were shipped as retail ready and held in a cool chain conditions until
sold to consumers, the risk of importation, establishment and spread would be greatly reduced”. (Reply of Professor
Cross, q. 98)106 See: Australia’s rebuttal submission, paras. 651-654; Australia’s first written submission, paras. 781-
783.107 See: Australia’s rebuttal submission, paras. 659-665.108 See: Australia’s rebuttal submission, paras. 659-665.

market circumstances at any given point of time. There is an established integrated supply
network for apples in Australia, with extensive facilities already in place, and there is also a need
for suppliers to meet weekly demand requirements and changing market specifications of major
supermarkets. It is therefore hard to imagine that there would not be some commercial
advantage in exporting bulk fruit to Australia. There would also be a freight costs advantage in
being able to ship containers loaded with bulk bins compared to containers loaded with packed
cartons or returnable crates.
114. Mr Chairman and Members of the Panel, Table 43 of the Final IRA Report illustrates that
there would be more than enough infested apples distributed to orchard packing houses for there
to be a reasonable likelihood of an establishment event taking place,109 even if the actual level of
infestation of New Zealand apples is somewhat lower than the IRA Team assumed on the basis
of the August 2005 data.
115. New Zealand has incorrectly suggested that the relationship between the level of viable
infestation (or the probability of importation) and the probability of entry, establishment and
spread, is a linear one.110 Even if there were only half as many infested apples as originally
estimated, this does not mean that the chance of a mating pair is also halved.
116. New Zealand’s claim that ALCM will need at least 13-18 days to emerge after removal
from cold storage has been refuted by Professor Cross. Professor Cross validated the
IRA Team’s judgment on this point, when he confirmed at the experts’ meeting that adults could
potentially emerge very quickly, and perhaps as quickly as within a couple of hours following
exposure to suitable environmental conditions.
109 See: Australia’s rebuttal submission, paras. 644-649.110 See: New Zealand’s second written submission, para. 2.694.

117. New Zealand’s claim that “the IRA’s conclusions were based on the assumption that all
ALCM present on New Zealand apples would simultaneously emerge as soon as the apples were
removed from cold storage”111 is simply wrong. The IRA Team’s analysis was focussed on “the
likelihood of at least one establishment and spread event happening” in light of the number of
apples that might arrive at particular locations.112 Emergence of individuals over a period of
time113 does not mean that a mating pair could not emerge simultaneously.114 It is important to
understand that batches of New Zealand apples sent to orchard packing houses will not be
isolated from each other. Rather, the regular and continuous arrival of apples means that groups
of infested apples will overlap and a mating pair could be generated from separate deliveries – as
Professor Cross noted, viable ALCM may remain dormant for a year or more before emergence.
118. Further, at the experts’ meeting, Professor Cross was clear in his opinion that the
IRA Team’s consideration of flight distance was reasonable. In the view of Professor Cross,
there is no reason to assume that a mated female would not be able to fly 200 metres, or perhaps
even further. Professor Cross has specifically criticised New Zealand’s arguments on this
issue.115
119. Australia does not consider that New Zealand has established any flaws with the Final
IRA Report so serious that would suggest that, if absent, they would have resulted in a materially
different conclusion on unrestricted risk for ALCM. Even though the potential consequences
may be “low”, as the IRA Team concluded,116 Professor Cross agreed that risk management was
required for ALCM.

120. If the unrestricted risk is above Australia’s ALOP, that means that risk management
measures are required, and the question then becomes what level of inspection would reduce that
risk to Australia’s ALOP. Dr Sgrillo agreed with Australia that the underlying level of
infestation is the appropriate factor for determining the requisite rate of inspection to reduce risk
to ALOP. ISPM No. 31 makes it clear that a 600-unit inspection would be insufficiently
sensitive for that purpose given the low level of ALCM-infestation on New Zealand apples.117
Australia submits that the Panel should find that Australia’s risk assessment and measures for
ALCM are valid.
Conclusion on the risk assessments for fire blight, European canker and ALCM
121. Mr Chairman and members of the Panel, in sum, Australia has shown you why New
Zealand’s arguments in relation to the risk assessments for the three pests at issue are flawed and
cannot be sustained.
122. In relation to methodology, Australia has demonstrated that New Zealand’s assertions on
methodology are deeply and irretrievably flawed. The Panel should dismiss them.
123. In relation to fire blight, New Zealand’s pathway argument has no basis in the SPS
Agreement or the ISPMs and the experts have provided valuable instruction in this regard. New
Zealand has failed to recognise that, far from being speculative, the fire blight pathway through
mature apples is substantially confirmed, albeit with some elements of uncertainty. Finally, New
Zealand’s own evidence and arguments fail to reliably show anything about rare events that
might occur in Australia’s circumstances.
117 Also, see: Australia’s rebuttal submission, paras. 682-687.

124. In relation to European canker, the IRA Team determined that there is a risk associated
with the importation of latently infected apple fruit and the experts accept that such a risk exists.
Australia’s measure of sourcing apples from orchards or blocks free of the disease is required to
reduce this risk to achieve Australia’s ALOP.
125. In relation to ALCM, as I have just noted, the lack of adequate data is beyond dispute,
and in these circumstances, New Zealand has failed to demonstrate there are serious flaws with
the IRA Team’s risk assessment. Better data is required in order to make a more definitive
assessment.
The measures at issue
126. Mr Chairman and Members of the Panel, turning briefly to the measures at issue.
Australia has made it clear that it considers that the Panel may make findings in respect of each
of the remaining measures at issue in this dispute – that is, both principal and ancillary
measures.118 However, New Zealand has still not demonstrated that each of those measures fall
within the definition of “SPS measure” when taken alone.
127. Before concluding, Australia would also like to clarify the measure at issue listed at the
eighth bullet point in New Zealand’s panel request, which relates to the processing of fruit by
registered packing houses. As it stands, New Zealand’s description of this measure119 suggests
that packing houses which process apples intended for Australia may not also process apples
sourced from non-registered orchards or apples intended for other markets. Such an
interpretation of Australia’s measure is incorrect. The Final IRA Report makes clear that apples
118 See: Australia’s rebuttal submission, paras. 63, 75, 79-80.119 New Zealand has described the measure in question as follows: “The requirement that packing houses
registered for export of apples process only fruit sourced from registered orchards.” See: New Zealand’s panelrequest, p. 2; New Zealand’s first written submission, para. 3.83. New Zealand referred to page 317 of Part B of the
Final IRA Report in support of its view that Australia imposes such a measure (see: New Zealand’s first written
submission, para. 3.83, fn 85).

intended for other markets may be processed by registered packing houses. Further, apples from
non-registered orchards may be packed by such packing houses, but not at the same time as
apples for Australia.120
Conclusion
128. Australia would like to close with a “real-world” example of Australia’s commitment to
seeing trade flow freely within the bounds of Australia’s ALOP. In 2000, Australia opened its
market to table grapes from the United States. Based on the experience and scientific data
collected once trade began, the measures applying to US table grapes have since been adjusted
five times. As a result of those changes, the relevant measures are now less trade restrictive, and
from initial trade worth A$4 million, trade has grown to be worth A$35 million in 2008-09. The
same review mechanisms that were applicable to US table grapes are available in the Final IRA
Report for New Zealand apples.
129. In this regard, the Western Australian government recently advised that it is no longer
pursuing eradication of apple scab. Accordingly, Australia has commenced a review of the
measures set out in the Final IRA Report for exporting apples to Western Australia. Australia
stands ready to allow commercially valuable trade to occur.
130. Thank you.
120 The Final IRA Report states: “Apples for other markets may be packed in conjunction with apples for
Australia provided that all apples have been sourced from orchards or orchard blocks registered for Australia. All
sorting, washing and packing operations for Australia must not be missed with operations for apples from non-
registered orchards at any time.” (Final IRA Report, Part B, p. 317.)
