The Minister's three propositions
41 The first of the three propositions Mr Hill advanced in oral argument as underpinned the Minister's submissions was that cases that had been decided before ABT17 had made it clear that the IAA did not need to hold an interview merely because it was minded to reach a different credibility finding from a delegate.
42 That proposition may be accepted but two observations must be made in qualification to it.
43 The first is that a number of those earlier cases involved the Court's rejection of the proposition that the ordinary principles of procedural fairness remained operative notwithstanding the terms of Part 7AA of the Migration Act. However, as Minister for Immigration and Border Protection v CRY16 [2017] FCAFC 210 is but an early example, the IAA is not discharged in the conduct of its decision making from the implied condition of legal reasonableness.
44 The second qualification is that whatever might otherwise be the authority of earlier decisions of this Court to the extent the reasoning of the High Court is to the contrary it is the latter which prevails.
45 The second proposition Mr Hill advances is that the ratio of DPI17 (a case in which a Full Court of this Court set aside a decision where the IAA had substituted its view of an applicant's credibility) is, properly understood, confined to an instance in which the delegate's overturned finding had been overtly and significantly based on an express assessment by the delegate of the applicant's demeanour.
46 That too may be accepted: but the necessary qualification is that DPI17 was decided prior to the reasoning of the High Court in ABT17 being available to the Full Court. Any expression of principle express or implied in DPI17 as might be understood to confine the operation of the principles of legal unreasonableness to any circumstance must be accommodated to whatever the High Court subsequently determined.
47 The third proposition, which Mr Hill accepted to be fundamental to the case the Minister was advancing, was that what the High Court had decided in ABT17 had not fundamentally changed "the scheme of Part 7AA as reflected in the prior jurisprudence". It had merely dealt with another specific situation akin to that in DPI17 confining that circumstance to where the authority's decision was wholly or substantially based on an assessment of demeanour. However it is not readily to be assumed that the reasoning of the High Court is to be read subject to the prior jurisprudence of this Court. Such a starting point unless justified by a clear foundation in the High Court's reasoning involves turning the hierarchy of authority on its head.
48 If the reasoning of the plurality of the High Court in respect of the principles of legal unreasonableness as would vitiate the IAA's decision were, as the primary judge held them to be, engaged in the facts of this matter, then I am equally bound by the High Court's reasoning whatever might be understood to have been the prior jurisprudence.
49 I therefore turn to the killing ground of this appeal: whether in the actual and concrete circumstances of that which was before the Delegate and the IAA, the principles expressed by the plurality in ABT17 rendered it legally unreasonable for the IAA to have reached a different conclusion to that of the Delegate without it having invited the Respondent to an interview to allow him the opportunity to allay the concerns the IAA must have at some point at least tentatively formed regarding his credibility.
50 In that regard I reject the submission the Minister advances at [32] of his written submissions that the reasoning of the plurality in ABT17 at [25] compels the conclusion that the appeal be allowed. That submission is as follows:
32. Crucially for this case, the plurality in ABT17 held that the IAA is not required to interview a referred applicant merely because credibility is in issue, or merely because the IAA comes to a different view as to credibility than did the delegate. Instead, for the plurality, the result in ABT17 turned on the IAA's use of demeanour in making its decision:
The (sic) IAA will act unreasonably if, without good reason, it does not invite a referred applicant to an interview in order to gauge his or her demeanour for itself before it decides to reject an account given by the referred applicant in an audio recorded interview which the delegate accepted in making the referred decision wholly or substantially on the basis of its own assessment of the manner in which that account was given. (emphasis said to be added but omitted)
(citations omitted)
51 That submission compresses the detailed reasoning of the plurality to a misleadingly brief summary. The passage the Minister quotes as authority for the submission advanced omits the introductory word "However" as commences the plurality's statement at [25]. When that word is incorporated it directs attention to how that reasoning fits with what the plurality had stated in the preceding text. Contrary to the implication of the Minister's submission I am satisfied that in context the passage at [25] does not stand alone as the distillation of the High Court's reasons, rather it is to be read an aspect of the significantly detailed analysis of the operation of the principles of legal unreasonableness as might intersect with credibility findings which was undertaken by the plurality in ABT17 (Kiefel CJ, Bell, Gageler and Keane JJ) as follows:
[11] The Code of Procedure empowers the Minister or a delegate, "if he or she wants to", to "get any information that he or she considers relevant" on the condition that, if he or she "gets such information", he or she "must have regard to that information in making the decision whether to grant or refuse the visa". The Minister or delegate is specifically empowered to invite the applicant to give additional information in any of three ways: "in writing", "at an interview between the applicant and an officer" or "by telephone". If the applicant is invited to give additional information at an interview, there is no need for the officer who conducts the interview to be the delegate who is going to decide whether to grant or refuse the visa. Nor is there any need for the interview to be conducted in person. Nor does any statutory provision govern the form in which the interview might be recorded or transcribed.
[12] Whatever the form in which any interview with a referred applicant conducted in accordance with the Code of Procedure might come to be recorded or transcribed, the record of the interview is material in the Secretary's possession or control which the Secretary could not but consider relevant to the review. The record can therefore be expected to form part of the review material which the Secretary will be obliged to give to the Authority and which the Authority will be obliged to examine for itself.
[13] However, the potential for a record of an interview conducted in accordance with the Code of Procedure to take a variety of forms creates potential for an informational gap to arise in the review material where an interview with the referred applicant has been conducted by the delegate in person and has been audio recorded but not video recorded. Provision of the audio recording as part of the review material will then not put the Authority in the position of having and being able to examine for itself the totality of the information available to the delegate and required by the Code of Procedure to be considered by the delegate when making the referred decision. Missing from the review material will be a visual impression of how the referred applicant appeared during the interview - his or her demeanour.
[14] An informational gap of that nature has potential to impact on the Authority's assessment of the credibility of the account given by the referred applicant during the audio recorded interview and in turn has potential to impact on the Authority's assessment of the referred applicant's overall credibility. "Impressions formed by a decision-maker from the demeanour of an interviewee may be an important aspect of the information available to the decision-maker." That has "long been recognised" and continues to be appreciated despite awareness on the part of sophisticated decisionmakers that "an ounce of intrinsic merit or demerit" measured by reference to objectively established facts and the apparent logic of events "is worth pounds of demeanour".
[15] The potential significance of demeanour is illustrated by the present case. Here, as will be seen, the Authority was troubled by a concern that the appellant's evidence in his audio recorded interview with the delegate was generally lacking detail and at times vague and hesitant. An interview was the obvious means by which the Authority might seek to resolve these matters of concern, given that the Authority was evidently not convinced by the country information alone to uphold the delegate's ultimate decision, however "plausible" the appellant's account of his personal circumstances might be. At an interview the Authority could seek answers in relation to those aspects of the appellant's evidence that troubled the Authority by raising questions which had not previously been raised with the appellant. The Authority could thus develop an informed impression of the credibility of the appellant based on his responses to such questions and an observation of his demeanour. The appellant's responses and the demeanour of the appellant inextricably associated with them would be new information relevant to his personal circumstances.
[16] There can be no doubt that the powers of the Authority to get and consider new information enable the Authority to bridge such an informational gap by inviting the referred applicant to a further interview to be conducted in person or by video link in order to assess and consider his or her demeanour for itself. The Authority's own visual impression of the referred applicant's appearance during such an interview would necessarily constitute new information within the power of the Authority to get because it would communicate knowledge of an evidentiary nature which would be open to be considered by the Authority to have the potential to bear on the Authority's assessment of the referred applicant's credibility and which was not before the Minister when the delegate made the referred decision. The new information so got by the Authority would then meet the preconditions to its consideration by the Authority on the basis that it was not and could not have been before the Minister when the delegate made the referred decision and on the basis of the Authority's satisfaction that the existence of any informational gap is sufficiently aberrant within the scheme of de novo review for which Pt 7AA provides to make existence of the informational gap in the particular review alone enough to constitute "exceptional circumstances" justifying its consideration irrespective of how frequently such an informational gap might arise in practice.
[17] Were some aspect of the referred applicant's appearance during the interview to end up being so glaringly undermining of the referred applicant's credibility as to lead the Authority to consider in advance of reasoning on the facts that the appearance of itself "would", as distinct from "might", be the reason or part of the reason for affirming the decision of the delegate, the Authority would come under an obligation to explain that to the referred applicant and to invite the referred applicant to comment. The Authority would be able to discharge that obligation by inviting the applicant to comment orally in the interview itself or subsequently in writing. But occasions when the need to take such a course might arise would be rare, as the circumstances of the present case again illustrate. The Authority was evidently inclined to reject the appellant's account of his experience of persecution because the Authority found the appellant's account vague and lacking in detail and to have been given in a hesitant fashion. An interview by the Authority would have enabled the Authority to get new information from the appellant by raising these issues with him. If the effect of this new information was that it simply failed to allay the tentative concerns that the Authority already entertained about the appellant's credibility, the obligation to invite further comment would not be engaged. The new information would not be the reason, or part of the reason, for affirming the fast track reviewable decision. The reason would remain the unallayed concerns of the Authority in relation to the appellant's account of his personal circumstances.
[18] The Authority being able to exercise its powers to get and consider new information to bridge an informational gap in the review material by inviting a referred applicant to an interview in order to gauge and consider his or her demeanour for itself, the question becomes as to when if at all compliance with the implied condition of reasonableness in the conduct of the review or in the consideration and exercise of those powers might compel the Authority to adopt that course. Contrary to the urging of the appellant, answering that question is not assisted by seeking to infuse the implied condition of reasonableness with notions of procedural fairness, separate implication of which is expressly excluded from the scheme of Pt 7AA.
[19] The answer is to be found in recognising that "[t]he implied condition of reasonableness is not confined to why a statutory decision is made; it extends to how a statutory decision is made" such that "[j]ust as a power is exercised in an improper manner if it is, upon the material before the decision-maker, a decision to which no reasonable person could come, so it is exercised in an improper manner if the decision-maker makes his or her decision in a manner so devoid of plausible justification that no reasonable person could have taken that course".
[20] Compliance with the implied condition of reasonableness in the performance by the Authority of its duty to review the decision of the delegate necessitates not only that the decision to which the Authority comes on the review has an "intelligible justification" but also that the Authority comes to that decision through an intelligible decision-making process. Thus, as has been recognised, there can be circumstances in which the Authority can transgress the bounds of reasonableness by treating particular information as the reason or part of the reason for the decision to which it comes without first exercising its powers to get and if appropriate to consider, as new information, further information capable of being provided by the referred applicant.
[21] Answering the question therefore requires an examination of the decision-making pathways reasonably open to the Authority in reviewing the decision of a delegate to determine for itself whether the criteria for the grant of a protection visa have been met where the review material that it is obliged to consider in making that determination leaves out information that was available to and required to be considered by the delegate.
[22] The mere existence of an informational gap will not necessarily result in the Authority being "disadvantaged in comparison with the delegate". That is because, having regard to country information and other information contained in the review material, the credibility of the referred applicant will not necessarily have a significant bearing on the Authority's determination of whether the criteria for the grant of a protection visa have been met. That is also because, having regard to country information and other information contained in the review material, how the referred applicant may have presented in the interview with the delegate will not necessarily have a significant bearing on such assessment of his or her credibility as the Authority might reasonably undertake.
[23] To the extent that the credibility of the referred applicant might bear on whether the Authority is to be satisfied that the criteria for the grant of a protection visa have been met and to the extent that his or her appearance in an interview with the delegate might bear on his or her credibility, it would ordinarily be open to the Authority to form its own assessment of credibility taking into account such second-hand description or impression of his or her appearance as might be conveyed expressly or by implication in the statement forming part of the review material which sets out the delegate's findings of fact and refers to the evidence on which those findings were based. Taking into account any such description or impression of the referred applicant's appearance, it would ordinarily then be open to the Authority to reach an assessment of the referred applicant's credibility without any need for the Authority's assessment of credibility to coincide with the delegate's assessment of credibility.
[24] The Minister is therefore correct to say that the Authority is not required to interview a referred applicant merely because credibility is in issue or merely because the Authority comes to a different view as to credibility than did the delegate.
[25] However, the Authority will act unreasonably if, without good reason, it does not invite a referred applicant to an interview in order to gauge his or her demeanour for itself before it decides to reject an account given by the referred applicant in an audio recorded interview which the delegate accepted in making the referred decision wholly or substantially on the basis of its own assessment of the manner in which that account was given. That is what happened in this case.
52 The reference in the plurality reasons at [22] to the IAA not being required to interview a referred applicant merely because credibility is in issue and the passage at [25] that the Minister relies upon are thus not to be understood as stand-alone propositions of law.
53 I discern nothing in the detailed consideration of the subject matter addressed by the plurality to suggest, as the Minister submits, that the High Court was intending in some unstated manner to defer to the prior existing jurisprudence of this Court. To the contrary I discern a focussed attention on the plurality's part to explicate the principles that decision makers must apply when an information gap exists, as would guide (and bind) the IAA, the judges of the Federal Circuit Court and this Court in the application of the relevant law.
54 I do not ignore the Minister's submission that "at the very least DGZ16 is good law because it is expressly cited by the plurality". However DGZ16 v Minister for Immigration and Border Protection & Anor (2018) 258 FCR 551 was not a case involving an alleged "information gap". Its citation by the plurality for the purpose of acknowledging that in most cases the IAA will have no duty not to reach a different conclusion to that of the Delegate on the basis of the materials before it, and that the lens through which any criticism of such reasoning is to be understood is that of legal unreasonableness rather than procedural fairness is consistent with rather than inconsistent with the plurality's reasons and in particular those expressed at [22]-[23].
55 There is nothing inconsistent in DGZ16 with the guidance the plurality in ABT17 provides at [22]-[23] with respect to the kinds of circumstances in which the principles of legal unreasonableness will not vitiate a decision the IAA has in contemplation reaching, and does form in an instance in which there is relevantly an "information gap" without it first having invited the referred applicant to an interview to afford him or her the opportunity to address the IAA's incipient concerns.
56 Applying that guidance, for the reasons that follow, I am satisfied that the circumstances identified in [22] and [23] do not apply in the present instance.
57 It is convenient to first address their Honours' reasoning at [22]. It will be recalled that it is in the following terms:
[22] The mere existence of an informational gap will not necessarily result in the Authority being "disadvantaged in comparison with the delegate". That is because, having regard to country information and other information contained in the review material, the credibility of the referred applicant will not necessarily have a significant bearing on the Authority's determination of whether the criteria for the grant of a protection visa have been met. That is also because, having regard to country information and other information contained in the review material, how the referred applicant may have presented in the interview with the delegate will not necessarily have a significant bearing on such assessment of his or her credibility as the Authority might reasonably undertake.
58 In the present case it may or may not have been lawfully open to the IAA to have affirmed the Delegate's decision on the simple basis that, accepting that the Respondent had conducted himself as the Delegate had found he had, but otherwise had not had any high level involvement with the LTTE and did not claim to have been involved in any separatist activities, he would not be at risk of persecution by the Sri Lankan authorities. In such a hypothetical instance the credibility of the referred applicant would not have had a significant bearing on the IAA's determination of whether the criteria for the grant of a protection visa had been met. The condition referred to in [22] of the plurality's reasons would be satisfied.
59 However that was not the course adopted by the IAA. It never got to that point because, it had concluded on the basis of its own assessment of the Respondent's want of credit, notwithstanding his truthfulness having been accepted by the Delegate, that he had lied about a previously unarticulated claim: it was a mere recent invention.
60 Nor was there country information before the IAA such as meant that how the Respondent may have presented to the Delegate could be concluded to be insignificant in respect of any assessment of his credibility. There was no such objective material of that nature before the Delegate and there was none before the IAA. His accepted claim turned exclusively on his credit: as did the IAA's rejection of it.
61 I turn now to what the plurality in ABT17 stated at [23]. It is as follows:
[23] To the extent that the credibility of the referred applicant might bear on whether the Authority is to be satisfied that the criteria for the grant of a protection visa have been met and to the extent that his or her appearance in an interview with the delegate might bear on his or her credibility, it would ordinarily be open to the Authority to form its own assessment of credibility taking into account such second-hand description or impression of his or her appearance as might be conveyed expressly or by implication in the statement forming part of the review material which sets out the delegate's findings of fact and refers to the evidence on which those findings were based. Taking into account any such description or impression of the referred applicant's appearance, it would ordinarily then be open to the Authority to reach an assessment of the referred applicant's credibility without any need for the Authority's assessment of credibility to coincide with the delegate's assessment of credibility.
62 Hypothetically such a circumstance might have applied had the Delegate had pressed his enquiry as to the Respondent's fears to the circumstance that the IAA regarded as "highly significant" to the degree entitling it to reach a finding of "recent invention" to which the respondent had provided a wholly implausible answer. That might have entitled the IAA to have reached a finding of "recent invention" within what the plurality identifies would have been available to it in [23].
63 But the Delegate's questioning of the Respondent had not gone to that point. As the transcript reveals (CB 423) the question asked of the Respondent about his prior non-disclosure was as follows:
In your arrival interview, you stated that you left Sri Lanka because you couldn't get a job. Um you didn't mention any of the claims you made, that you have in your application
64 The IAA's reasons identify nothing it found to be implausible about the Respondent's answer to that question. To the contrary it expressly accepted that an asylum seeker might be reluctant to disclose an association with an organisation such as the LTTE during his first encounter with officials of a foreign government. The Delegate reached a state of satisfaction as to the Respondent's credit on that basis. To have reached an affirmative degree of satisfaction that the claimed events had occurred without testing that further proposition might be thought to have been naïve on the Delegate's part but there was nothing in the referred review as could engage with the principles stated in [23]. The materials before it were not such as on that principle permitted the IAA to reach a contrary credit finding (on the premise of a question neither asked nor answered) without any need for the IAA assessment of credibility to coincide with that of the Delegate.
65 The Court has earlier observed that it is satisfied that the text in [25] of the plurality's reasons in ABT17 is to be understood and applied having regard to their Honour's earlier more detailed analysis. It is in that more comprehensive analysis that, to use a perhaps inelegant metaphor, the principles to be applied in sorting the sheep (when an invitation must be issued) from the goats (when it need not be) is identified by the plurality.
66 On that basis I reject the Minister's submission that the text in [25] that singularly focusses on an particular instance in which the plurality then more particularly identified as one in which the IAA "will act unreasonably" is to be understood, in the negative, to describe the universe of such circumstances - rather I am satisfied that the specificity of that observation is directed towards focussing the generality of the plurality's earlier reasoning on their application in a factual matrix requiring specific attention as the plurality proceed to address in greater detail immediately following at [26]-[29] under the heading "The principles applied".
67 It may be that in strict law the earlier reasoning in ABT17 is "obiter". However the primary judge was correct to have regarded himself as subject to the duty, if not formally bound, to apply the law as had been stated in considered reasoning of a majority of the High Court.
68 I therefore reject that the circumstance that the Respondent's claim had been made for the first time only during the hearing is a circumstance that justified the IAA dispensing with itself being required to interview the referred applicant before rejecting his credit. That a claim has not been earlier advanced may well have been a sound reason for scepticism - but, particularly in the case of persons who are claiming to have fled persecution from civil and military authority in their home country in the absence of testing the want of a good reason for not speaking before is not open to be assumed: see for example UNHCR, Handbook and Guidelines on Procedures and Criteria for Determining Refugee Status under the 1967 Protocol Relating to the Status of Refugees, December 2011, HCR/1P/4/ENG/REV.3 at [198].
69 In any event to proceed on that premise would be inconsistent with what the plurality in ABT17 states at [23]. That in turn is reinforced by their Honour's earlier reasoning at [14] which prefaces their analysis in respect of the position of credit findings as follows:
[14] An informational gap of that nature has potential to impact on the Authority's assessment of the credibility of the account given by the referred applicant during the audio recorded interview and in turn has potential to impact on the Authority's assessment of the referred applicant's overall credibility. "Impressions formed by a decision-maker from the demeanour of an interviewee may be an important aspect of the information available to the decision-maker." That has "long been recognised" and continues to be appreciated despite awareness on the part of sophisticated decision makers that "an ounce of intrinsic merit or demerit" measured by reference to objectively established facts and the apparent logic of events "is worth pounds of demeanour".
(citations omitted)
70 The primary assessor of the Respondent's credit in this matter was the Delegate. The Delegate was aware that the Respondent's claim had not been earlier advanced. He had tested the truth of the Respondent's claims perhaps less robustly than might have other decision makers but it cannot be suggested that the Delegate ignored that issue. Having tested the Respondent's explanation (and by necessary implication his honesty in that regard) the Delegate accepted the Respondent's claim to have transported fuel to the LTTE. Other claims he rejected. The benefit the Delegate was entitled to have enjoyed in making those findings (necessarily dependent on his assessment of the Respondent's demeanour and truthfulness; his credit) was an advantage the plurality in ABT17 specifically acknowledged.
71 The scheme of Part 7AA of the Migration Act provides for a statutorily confined system of merits review. That confined system entirely excludes the operation of the ordinary rules of procedural fairness as would otherwise have required the IAA to hear from the Respondent before substituting for the Delegate's finding one dependent of it having formed an adverse view of the Respondent's credit and honesty. However as the plurality in ABT17 reconfirms nevertheless there are circumstances in which the IAA can transgress the bounds of legal unreasonableness by treating particular information as the reason or part of the reason for the decision to which it comes without first exercising its powers to get and if appropriate to consider, as new information, further information capable of being provided by a referred applicant.
72 To the extent that the Minister may be correct that the primary judge expressed his reasoning at [37] too broadly, I nonetheless apprehend no appealable error in his Honour's application of the principles articulated by the plurality in ABT17.
73 I would dismiss Ground 2 of the Minister's appeal.
