The principles of legal unreasonableness
84 Mr Crowley for the appellants submitted that, in the circumstances described above, the Authority's failure to exercise its discretion under s 473DC to "get" the obituary document was legally unreasonable. That submission requires consideration of the principles identified in Minister for Immigration and Border Protection v SZVFW (2018) 264 CLR 541 (SZVFW) which concerned the scope of the principles of "legal unreasonableness" in the exercise of discretionary administrative powers. In that case Kiefel CJ (at 550-551 [10]) in reliance on the majority in Minister for Immigration and Citizenship v Li (2013) 249 CLR 332 at 367 [76], identified that legal unreasonableness exists where the exercise of power lacks an evident and intelligible justification such that no reasonable person could have arrived at that decision in the sense that it is irrational. In addition, her Honour said (at 551 [11]) that the test is necessarily stringent and the courts will not lightly interfere with the exercise of a statutory power involving an exercise of discretion. In SZVFW it was also held that whether the exercise of an administrative decision is unreasonable requires close attention to the scope, purpose and objects of the statutory source of the power in question: at 565 [54] per Gageler J, at 572 [79] per Nettle and Gordon JJ, and at 586 [135] per Edelman J.
85 The reluctance of a court to conclude that a discretionary power has been exercised unreasonably was recently emphasised in Minister for Immigration and Border Protection v Haq (2019) 365 ALR 202 at 211 [37] per Griffiths J:
It is also well established that a statutory discretionary power contains an area of decisional freedom (see, for example, Li at [28] per French CJ and at [66] per Hayne, Kiefel and Bell JJ). The "courts will not lightly interfere with the exercise of a statutory power involving an area of discretion", and an important question "is where that area lies" (see SZVFW High Court at [11] per Kiefel CJ). As Gageler J stated in SZVFW High Court at [58], a judicial review should not enter the zone of discretion committed to the administrator, by the judicial review judge forming his or her own conclusion (see also Minister for Immigration and Border Protection v Stretton (2016) 237 FCR 1; 329 ALR 491; [2016] FCAFC 11 (Stretton) at [21] per Allsop CJ and at [76] per Griffiths J). In applying a standard of legal reasonableness the Court should not substitute the Court's view as to how a discretion should be exercised for that of the decision-maker. Moreover, depending upon the terms of the relevant discretionary power, the decision-maker will generally have "a degree of latitude in determining what is fair and just in a given case" (SZVFW High Court at [13] per Kiefel CJ). More recently, the High Court has described the standard of legal unreasonableness which is implied as a condition of the exercise of a statutory power as "a demanding standard" (see TTY167 v Republic of Nauru (2018) 362 ALR 246; [2018] HCA 61 (TTY167) at [24] per Gageler, Nettle and Edelman JJ).
86 The issue of whether the Authority's failure to exercise or to consider exercising its discretion under s 473DC to "get" new information was legally unreasonable arose in BJK17 v Minister for Immigration and BJJ17 v Minister for Immigration [2019] FCAFC 171. In that context the Full Court (Middleton, Bromberg and Snaden JJ) observed (at [41]):
Powers conferred by statute must, ordinarily, be exercised reasonably: Li, 351 [29]-[30] (French CJ), 362 [63] (Hayne, Kiefel and Bell JJ), 370 [88]-[89] (Gageler J). The power conferred upon the Authority by s 473DC to get "new information" is subject to that requirement: Plaintiff M174/2016 v Minister for Immigration and Border Protection (2018) 353 ALR 600 ("M174"), 607 [21], 613 [49], 618 [71] (Gageler, Keane and Nettle JJ), 620-621 [86] (Gordon J), 624 [97] (Edelman J); DPI17 v Minister for Home Affairs (2019) 366 ALR 665 ("DPI17"), 667 [36] (Griffiths and Steward JJ), 689 [91] (Mortimer J). There are no fixed categories of circumstances by reference to which a failure to exercise, or consider exercising, the discretion might be impugned as legally unreasonable: CCQ17 v Minister for Immigration and Border Protection [2018] FCA 1641, [42] (Thawley J). Rather, an assessment of whether, in any given case, the exercise or non-exercise of the discretion is attended by legal unreasonableness must, of necessity, be case-specific: Minister for Immigration and Border Protection v Singh (2014) 231 FCR 437, 445 [42] (Allsop CJ, Robertson and Mortimer JJ). A decision will not be impugned as legally unreasonable simply because it is one about which different minds might form different views: Plaintiff S111/2017 v Minister for Immigration and Border Protection (2018) 263 FCR 310, 328 [66] (Perry J, with whom McKerracher and Charlesworth JJ agreed).
87 The context of the exercise of the power or the omission to consider exercising the power in s 473DC(1) was that the Authority was to review the fast-track decision on the papers provided to it under s 473CB of the Act (under s 473DB of the Act) without accepting or requesting additional information and without interviewing. Whilst the Authority was entitled to obtain "new information", it was not obliged to do so: s 473DC of the Act. The provisions of Part 7AA are intended to provide an expedited consideration of the visa application. That said, such a review must conform to the natural justice requirements expressed and implied in the part. In EVS17 v Minister for Immigration and Border Protection (2019) 163 ALD 422 at 430 [33] the Full Court (Allsop CJ, Markovic and Steward JJ) identified the purpose of the Part in the following terms:
The intent of Pt 7AA is to provide an efficient, but fair, process of review in accordance with the terms of the Act: see [18]-[19] above. The Authority is expressly required to pursue that objective by providing a "mechanism of limited review that is efficient, quick, free of bias and consistent with Division 3": s 473BA. Division 3 sets out the way in which the Authority is to conduct the review. It expressly confines the material to which the Authority may have regard in undertaking its review to the material provided by the Secretary under s 473CB and, except in the limited circumstances set out in Subdiv C of Div 3, without accepting or requesting new information or interviewing the applicant. Further, in undertaking its review, the Authority is not concerned with the correction of error on the part of the Minister or delegate but undertakes a de novo consideration of the merits of the decision referred to it. It is required to consider the application afresh and determine for itself whether the criteria for a protection visa have been met: see Plaintiff M174/2016 v Minister for Immigration and Border Protection (2018) 92 ALJR 481; 353 ALR 600; [2018] HCA 16 at [17].
88 In DPI17 v Minister for Home Affairs (2019) 366 ALR 665 Griffiths and Steward JJ identified the manner in which the context of Part 7AA demarcates the scope of legal unreasonableness in connection with the Authority's powers conferred by it. Their Honours listed six relevant propositions at 676 [35]:
(1) as stated in the simplified outline of Pt 7AA in s 473BA of the Act, Pt 7AA provides "a limited form of review" of a "fast track decision" which is constituted by a refusal to grant a protection visa to an applicant who is statutorily designated to be a "fast track applicant" (at [1]);
(2) the task of the IAA in conducting a review of a fast track reviewable decision is not to correct error on the part of the Minister or a delegate, but rather the IAA "is engaged in a de novo consideration of the merits of the decision that has been referred to it." The IAA must consider the application afresh and determine for itself whether the criteria for the grant of the visa have been satisfied (at [17]);
(3) the various powers conferred upon the IAA by Div 3 of Pt 7AA (including s 473DC) are conferred on the implied condition that they are to be exercised within the bounds of reasonableness, as explained in Minister for Immigration and Citizenship v Li [2013] HCA 18; 249 CLR 332 (Li) (at [21]);
(4) the term "new information" must be read consistently when used in ss 473DC, 473DD and 473DE "as limited to 'information' (which may or may not be recorded in a document), in the ordinary sense of a communication of knowledge about some particular fact, subject or event, that meets the two conditions set out in s 473DC(1)(a) and (b)." These two conditions are that the information was not before the Minister or delegate when the protection visa decision was made, and the IAA considers the information to be relevant (at [24]);
(5) although there is no general requirement for the IAA to give to the applicant material provided to the IAA by the Secretary (s 473DA(2)), there is nothing in Pt 7AA to preclude the IAA from giving the whole or some part of that material to the applicant in the context of exercising the power under s 473DC(3) to invite the giving of new information and s 473DA(2) does not address what may be required of the IAA in particular circumstances in order to exercise that power reasonably ([26]); and
(6) s 473DE is concerned to ensure that the referred applicant has an opportunity to address new information that has been, or is to be considered by, the IAA under s 473DD and that would be the reason, or a part of the reason, for affirming the fast track reviewable decision (at [35]).
89 Subsequently, their Honours emphasised the fact specific nature of any analysis directed to ascertaining whether the exercise or non-exercise of a power was legally unreasonable (at 677 [37]):
… First, legal unreasonableness is "invariably fact dependent and requires evaluation of the evidence" (see Minister for Immigration and Border Protection v Singh [2014] FCAFC 1; 231 FCR 437 (Singh) at [47] per Allsop CJ, Robertson and Mortimer JJ and see also SZVFW at [84] per Nettle and Gordon JJ). Secondly, the correct approach is to apply the relevant general principles to the particular factual circumstances of the case and not to engage in an analysis which merely involves identifying particular factual similarities or differences between individual cases (Singh at [48] and Haq at [32]). It may well be that, for this reason, the appellant made clear that, on the appeal, he did not rely on DFW16. As Thawley J pointed out in CCQ17 v Minister for Immigration and Border Protection [2018] FCA 1641 (CCQ17) at [42], there are no fixed categories of circumstances in which it would be legally unreasonable to fail to consider the discretion in s 473DC. Thirdly, having regard to the clear terms of s 473DA (which provides that Div 3 of Pt 7AA and ss 473GA and 473GB are taken to be an exhaustive statement of the requirements of the natural justice hearing rule in relation to IAA reviews), the starting point for analysis in a case such as this which raises the ground of legal unreasonableness is not through a "natural justice lens" (DGZ16 at [69] and [72] per Reeves, Robertson and Rangiah JJ). Fourthly, as Thawley J correctly stated in CCQ17, merely because there has been a failure to consider the exercise of the power in s 473DC does not of itself involve error, let alone a jurisdictional error.
