consideration of ground one
34 It was not legally unreasonable for the Authority not to have delayed its review to receive the IHMS records or to seek to obtain the records itself under s 473DC of the Act for the following reasons.
35 The Authority was conducting a "fast track review" under Part 7AA of the Act where the objective is to provide a mechanism of limited review that is efficient, quick, free of bias and consistent with Division 3 of the Act. The Authority conducting a fast track review ordinarily does not have hearings, and is required to review decisions on the papers that are provided to it by the applicant. In exceptional circumstances, the Authority may consider new material and may invite referred applicants to provide new information at an interview or in writing.
36 Demonstrating legal unreasonableness in the context of a limited form of review under Part 7AA of the Act carries a "demanding standard": DCP16 at [110]. The decision of the Authority not to delay making a decision under review was not legally unreasonable in circumstances where the Authority had substantial evidence of the appellant's mental health problems before it and, in its Reasons at [27], accepted that the appellant suffered from severe mental health issues.
37 The Authority, under the limited form of review provided by Part 7AA, was required to conduct a review which was "efficient" and "quick" and "on the papers" except in exceptional circumstances: ss 473DB and 473FA of the Act. In circumstances where the Authority was not provided with a timeframe as to when the IHMS medical records would be available and where there were no particulars provided as to why the IHMS records would provide anything different from the mental health records which the Authority already had and accepted the Authority's conduct was not legally unreasonable. I do not accept the appellant's submission that the IHMS records "went to something altogether different to any material that related simply to the nature of the appellant's mental health". The appellant's legal representatives did not know of the content of the IHMS records. In this regard, the primary judge in the Primary Judgment at [29] was correct to observe that there was no evidence that the IMHS records were "likely to contain materially different information to that upon which the [Authority] relied". It was not legally unreasonable for the Authority to proceed with the review in the absence of the further information which would apparently only serve to further confirm that the appellant suffered from severe mental health issues.
38 The Authority in its Reasons at [12] provided an intelligible justification for not delaying the review.
39 I accept the Minister's submission that once the Authority accepted that the appellant suffered from severe mental health issues, the question for the Authority was not the severity of the appellant's health, but rather whether the appellant would face a well-founded fear of persecution, for that reason, including whether any asserted persecution involved "systemic and discriminatory conduct" under s 5J(4)(c) of the Act.
40 The Authority did not act unreasonably in deciding not to exercise its discretion under s 473DC of the Act to seek the IHMS medical records itself.
41 The power in s 473DC of the Act is conferred on the Authority with the implied condition that it is to be exercised reasonably, in the sense explained in Minister for Immigration and Citizenship v Li [2013] HCA 18; 249 CLR 332 (Li): Plaintiff M174 at [21] per Gageler, Keane and Nettle JJ, [86] per Gordon J and [97] per Edelman J; CRY16 v Minister for Immigration and Border Protection at [82]-[83] per Robertson, Murphy and Kerr JJ; Minister for Immigration and Border Protection v DZU16 [2018] FCAFC 32; 253 FCR 526 (DZU16) at [93] per Robertson, Murphy and Kerr JJ; DPI17 v Minister for Home Affairs [2019] FCAFC 43; 366 ALR 665 (DPI17) at [43] per Griffiths and Steward JJ; BJK17 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2019] FCAFC 171 (BJK17) at [41] per Middleton, Bromberg and Snaden JJ.
42 The considerations that inform the standard as to whether or not the exercise of statutory power is legally reasonable have been detailed elsewhere: see, for example, Minister for Immigration and Border Protection v Haq [2019] FCAFC 7; 365 ALR 202 at [37] per Griffiths J, with Gleeson J agreeing and Khalil v Minister for Home Affairs [2019] FCAFC 151; 372 ALR 424; 166 ALD 1 at [34]-[35] per Logan, Steward and Jackson JJ. It is convenient to quote Allsop CJ, Griffiths and Wigney JJ in Stretton at [11], where their Honours expressed that the task of evaluating whether a statutory decision was made within its jurisdictional boundaries of power
is not definitional, but one of characterisation: the decision is to be evaluated, and a conclusion reached as to whether it has the character of being unreasonable, in sufficiently lacking rational foundation, or an evident or intelligible justification, or in being plainly unjust, arbitrary, capricious, or lacking common sense having regard to the terms, scope and purpose of the statutory source of the power, such that it cannot be said to be within the range of possible lawful outcomes as an exercise of that power.
43 In the context of Part 7AA of the Act, the zone of decisional freedom in which the Authority may lawfully determine not to seek "new information" is particularly broad: DCP16 at [110].
44 The standard of the legal reasonableness applicable to the exercise of statutory power takes it content and boundaries from the text, context, subject matter and purpose of the particular statutory content in which the relevant power has been exercised: DCP16 at [106]. In the present case, the Authority was required to conduct an efficient and quick review: s 473DC(1) of the Act. This operates to make the task in establishing legal unreasonableness more demanding: TTYI67 v Republic of Nauru [2018] HCA 61; 362 ALR 246 at [24] per Gageler, Nettle and Edelman JJ.
45 Although the Authority is empowered to request further information, it is not under a duty to get, request or accept any such information: s 473DC(2) of the Act. The fact that the Authority did not seek for itself the IHMS records was within the zone of decisional freedom in which the Authority may lawfully determine not to seek new information. The Authority's reasons for not seeking new information under s 473DC of the Act with regard to the appellant's mental health was, in the circumstances, explained by the Authority at [12] of its Reasons and had an intelligible justification for not doing so.
