Relevant statutory provisions
59 Division 3 of Pt 7AA of the Migration Act governs the conduct of a review by the IAA of a "fast track reviewable decision". There is no dispute that the delegate's decision was a "fast track reviewable decision".
60 Within Div 2 of Pt 7AA, s 473CC requires the IAA to review a "fast track reviewable decision" referred to it by the Minister under s 473CA. Division 3 of Pt 7AA (with ss 473GA and 473GB) "is taken to be an exhaustive statement of the requirements of the natural justice hearing rule in relation to reviews conducted" by the IAA: see s 473DA. Relevantly here, s 473DB sets out the "primary requirement" that the IAA is to review a decision referred to it by considering the review material provided to it by the Secretary under s 473CB without accepting or requesting new information and without interviewing the referred applicant: Plaintiff M174/2016 v Minister for Immigration and Border Protection [2018] HCA 16; 264 CLR 217 at [22]. Section 473DB(1) provides as follows:
(1) Subject to this Part, the Immigration Assessment Authority must review a fast track reviewable decision referred to it under s 473CA by considering the review material provided to the Authority under section 473CB:
(a) without accepting or requesting new information; and
(b) without interviewing the referred applicant.
61 Subdivision C of Div 3 provides for exceptions to the general rule that the IAA is not to accept or request new information. Sections 473DC and 473DD are most relevant in this case.
62 Section 473DC is facultative. It is concerned with the circumstance in which the IAA can get ("in the sense of seek out": Plaintiff M174 at [23]) "new information", being information that the IAA considers may be relevant and that was not before the Minister or delegate at the time of deciding to refuse to grant the protection visa: Plaintiff M174 at [24]. Section 473DC provides:
(1) Subject to this Part, the Immigration Assessment Authority may, in relation to a fast track decision, get any documents or information (new information) that:
(a) were not before the Minister when the Minister made the decision under section 65; and
(b) the Authority considers may be relevant.
(2) The Immigration Assessment Authority does not have a duty to get, request or accept, any new information whether the Authority is requested to do so by a referred applicant or by any other person, or in any other circumstances.
(3) Without limiting subsection (1), the Immigration Assessment Authority may invite a person, orally or in writing, to give new information:
(a) in writing; or
(b) at an interview, whether conducted in person, by telephone or in any other way.
63 Section 473DD imposes restrictions on when the IAA can consider new information:
For the purposes of making a decision in relation to a fast track reviewable decision, the Immigration Assessment Authority must not consider any new information unless:
(a) the Authority is satisfied that there are exceptional circumstances to justify considering the new information; and
(b) the referred applicant satisfies the Authority that, in relation to any new information given, or proposed to be given, to the Authority by the referred applicant, the new information:
(i) was not, and could not have been, provided to the Minister before the Minister made the decision under section 65; or
(ii) is credible personal information which was not previously known and, had it been known, may have affected the consideration of the referred applicant's claims.
64 In their joint judgment in AUS17, Kiefel CJ, Gageler, Keane and Gordon JJ stated at [11]:
Logic and policy…demand that the Authority assess such new information as it might obtain from the referred applicant first against the criteria specified in both s 473DD(b)(i) and s 473DD(b)(ii) and only then against the criterion specified in s 473DD(a).
65 In order to meet s 473DD(b)(i), the IAA must be satisfied that the new information given, or proposed to be given, by the referred applicant was not, and could not have been, provided to the Minister before the Minister or delegate made the decision to refuse to grant the protection visa. To meet the requirement in s 473DD(b)(ii), the IAA must be satisfied that the new information given, or proposed to be given, by the referred applicant: (1) is credible information about an identified individual, or an individual who is reasonably identifiable; (2) was not previously known by either the Minister or the referred applicant; and (3) had the information been known by either the Minister or the referred applicant, may have affected the consideration of the referred applicant's claims: see Plaintiff M174 at [34].
66 The criterion in s 473DD(a) must always be met before the IAA can consider new information. In Plaintiff M174 at [30], Gageler, Keane and Nettle JJ said:
Quite what will amount to exceptional circumstances is inherently incapable of exhaustive statement. The word "exceptional", in such a context, is not a term of art but "an ordinary, familiar English adjective": "[t]o be exceptional a circumstance need not be unique, or unprecedented, or very rare: but it cannot be one that is regularly, or routinely, or normally encountered".
67 In AUS17, their Honours also observed at [12], with respect to the two limbs of 473DD:
[T]he Authority does not perform the procedural duty imposed on it by s 473DD in its conduct of a review if it determines in the purported application of the criterion in s 473DD(a) that exceptional circumstances justifying consideration of new information obtained from the referred applicant do not exist without first assessing that information against the criteria specified in both s 473DD(b)(i) and s 473DD(b)(ii) and then taking the outcome of that assessment into account in its assessment against the criterion specified in s 473DD(a).
68 In pursuing this inquiry, however, the Court is not required to engage in a formulaic consideration of s 473DD(b) and it may be able to infer that (b)(i) and (ii) have been satisfied, even if the precise statutory language of those provisions has not been used: APH17 at [79]. In this context, it is relevant that the IAA's duty to give reasons under s 473EA does not require it to give reasons for the exercise or non-exercise of a procedural power, such as ss 473DC or 473DD: see BVD17 v Minister for Immigration and Border Protection [2019] HCA 34; 373 ALR 196 at [16].
69 Furthermore, having assessed the new information against the criteria in s 473DD, "the Authority must take that new information into account in making its decision on the review if those criteria are met and must not take that new information into account in making its decision on the review if those criteria are not met": see AUS17 at [6].
