Ground three: legal unreasonableness
41 By his third ground of appeal, the appellant contended that the IAA Decision was attended by jurisdictional error insofar as it was made without the Authority's having first obtained, or considered obtaining, new information from him concerning the so-called "data breach". That failure to obtain, or consider obtaining, new information, he contended, was legally unreasonable, such that the resultant decision should be thought to have been beyond what the Authority had jurisdiction to decide.
42 The principles concerning legal unreasonableness are not presently in doubt. They were set out (in a similar context) in BJK17 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs (2019) 272 FCR 15, 24-25 [41]-[43] (Middleton, Bromberg and Snaden JJ):
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).
In DPI17, this court considered the boundaries of legal unreasonableness within which the Authority is constrained when exercising power under Pt 7AA of the Act. Griffiths and Steward JJ, referring to the plurality judgment in M174, listed (at [35]) six relevant propositions, namely that:
(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]).
Their Honours then (at [37]) added a further four observations on that theme:
…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.
43 At issue presently, is whether the Authority's failure to get, or consider getting, "new information" from the appellant about the so-called "data breach" was outside of its "decisional freedom": Minister for Immigration and Border Protection v Eden (2016) 240 FCR 158, 171 [62] (Allsop CJ, Griffiths and Wigney JJ). If the only course reasonably available to the Authority was to get or consider getting new information from the appellant, then its failure to do so will bespeak legal unreasonableness and its ultimate decision might be impugned as the product of jurisdictional error. The task, as Thawley J put it in CCQ17 v Minister for Immigration and Border Protection [2018] FCA 1641 (at [51]), is to:
…evaluate the failure to see whether it has the character of being legally unreasonable, perhaps in lacking a rational foundation or an evident or intelligible justification, or in being plainly unjust, arbitrary, capricious, or lacking in common sense.
44 In the present case, the existence of the so-called "data breach" was a matter of which the appellant had been made aware prior to the Delegate's Decision. The degree to which it bore upon his Visa Application was, then, a matter in respect of which he had had an opportunity to advance whatever submissions he felt might assist him. His complaint - both now and before the FCCA - was that he was not given any opportunity to do so after the Authority took account of the "Guardian article".
45 It is to be recalled that the "Guardian article" was of limited significance. It did not add to what was already known: namely, that the so-called "data breach" had not resulted in the publication of individual asylum claims. By his written submissions, the appellant contended that he had been "…denied the opportunity to…comment on what might be the inferences the Sri Lankan authorities could draw based on the names, date[s] of birth, nationalities and other personal identifiers of persons in detention".
46 In order that its failure to get, or consider getting, new information from the appellant might be impugned as legally unreasonable, it must first be shown that the Authority must have had reason to believe that he possessed some relevant information relating to the data breach that might assist it in conducting its review. Absent some belief, or basis for belief, of that kind, it could not be said that the only course reasonably open to the Authority was to obtain, or consider obtaining, that new information. If all that existed was a mere possibility that the appellant might have something useful to say that had not already been said, the Authority's failure to extend, or consider extending, to him an invitation to say it would fall short of the threshold of legal unreasonableness. In that circumstance, there would be an evident and intelligible (and, indeed, a fairly orthodox and obvious) basis for not extending an invitation under s 473DC of the Act.
47 Insofar as concerns the information that the appellant might have provided to the Authority had he been invited to provide any, two observations bear noting. First, it is anything but clear that he might have had anything relevant or useful to say about the so-called data breach that he had not already had an opportunity to say. Second, the appellant does not now identify any such information. Not only is there no basis upon which to conclude that the Authority ought to have known or assumed that the appellant had relevant new information, there is also no basis upon which positively to conclude that any information that he did have might have materially assisted the Authority, such that it might have been led to a different conclusion had it been obtained.
48 For at least those reasons, the Authority's failure to get, or consider getting, new information from the appellant about the so-called "data breach" was not legally unreasonable. The appellant's third appeal ground is not made good.
