5.1 Part 7AA of the Migration Act and relevant principles
42 Ground 1 alleges that the Authority did not comply with s 473DD as construed by the High Court in AUS17. The relevant principles were not in issue and may be shortly stated.
43 Part 7AA of the Migration Act provides for the review by the Authority of a "fast track reviewable decision". Although the Authority's review is a de novo (i.e. fresh) consideration of the merits of the fast track reviewable decision, s 473DB(1) of the Act provides that, subject to Pt 7AA of the Act, the Authority must review a fast track reviewable decision "by considering the review material provided to the Authority", "without accepting or requesting new information" and "without interviewing the referred applicant". The "review material" refers to the material provided under s 473CB to the Authority by the Department and includes the statement of reasons by the primary decision-maker, material provided by the referred applicant to the primary decision-maker, and any other material which is in the Secretary's possession or control and which the Secretary considers relevant to the review. The term "new information" is defined by ss 473BB and 473DC(1) to mean documents or information that were not before the Minister when the Minister made the decision to grant or refuse to grant the visa under s 65 of the Act and which the Authority considers may be relevant. The term "information" is used in its ordinary sense of a communication of knowledge about a particular fact, subject or event: Plaintiff M174/2016 v Minister for Immigration and Border Protection [2018] HCA 16; (2018) 264 CLR 217 at [24] (Gageler, Keane and Nettle JJ).
44 It follows that the primary rule (or default position, as it is sometimes also described) under Part 7AA is that the Authority reviews a decision referred to it "by considering the review material provided to the Authority under s 473CB without accepting or requesting new information and without interviewing the referred applicant": M174/2016 at [22].
45 The exception to the primary rule is contained in s 473DC of the Act, entitled "Getting new information". Subsections (1) and (3) of s 473DC confer a power on the Authority to obtain new information in these terms:
(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.
…
(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.
(Emphasis in underlining added.)
46 The use of the word "may" in subs 473DC(1) and (3) makes it clear that the Authority has a discretion to get new information, including to invite a person to give evidence. Subsection (2), in turn, makes clear that the Authority is under no obligation to obtain or accept any new information. That provision states that:
(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.
47 Importantly for present purposes, the discretion to get new information is exercisable only in very limited circumstances. Specifically, s 473DD imposes certain criteria which must be met before the Authority may consider new information. That provision provides:
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.
48 With respect to s 473DD, first, the reference to "credible personal information which was not previously known" has been construed to mean credible personal information not previously known to the Minister, as opposed to the visa applicant: CSR16 v Minister for Immigration and Border Protection [2018] FCA 474, [41]-[42] (emphasis added).
49 Secondly, as the appellant submitted, expressing doubts about the reliability of information is not the same in terms or in substance as a finding that information is not credible. As Bromberg J, for example, stated at [41]-[42] in CSR16:
In my view all that the "credible" element of the s 473DD(b)(ii) criteria requires is the Authority's satisfaction that the "new information" is information which is open to be or capable of being accepted by the Authority as truthful (or accurate, or genuine). It is only at the deliberative stage of its review that the Authority will be required to determine whether or not the "new information" is true. The s 473DD(b)(ii) criteria is concerned with an earlier or anterior stage of the review directed at whether "new information" should be received by the Authority so that it may be considered at the deliberative stage.
The criteria is a filtering mechanism designed to separate information worthy of consideration at the deliberative stage from that which is not. In that context, the word "credible" is used in relation to information, not in the sense that the information is believed, but in the sense that the information is capable of being believed. It is only information that the Authority is satisfied is "evidently not credible" (VEAL v Minister for Immigration and Multicultural Affairs (2005) 225 CLR 88 at [17] per Gleeson CJ, Gummow, Kirby, Hayne and Heydon JJ) that fails to meet the credibility requirement imposed by the s 473DD(b)(ii) criteria.
(Emphasis added.)
50 Thus, his Honour held that the Authority had fallen into jurisdictional error in that case by deciding whether the information was true or believed in applying the s 473DD(b)(ii) criterion, and thereby imposed a higher standard of satisfaction than that imposed by the statutory criterion: at [43].
51 Justice Bromberg's approach was endorsed by Mortimer J (as her Honour then was) and Jackson J in Minister for Immigration, Citizenship, Migrant Servies and Multicultural Affairs v BTW17 [2020] FCAFC 159; (2020) 294 FCR 150 at [75]. As their Honours explained in BTW17 at [75], it is the decision as to whether the information has the character of being "capable of being believed … as well as the character of being 'personal' to the visa applicant, which is to be made at this procedural stage, for the purpose of deciding what the scope of the review material should be, and whether there should be a departure from the primary rule." It follows, as the appellant emphasised, that the requirement in s 473DD(b)(ii) that the new information be "credible" sets a low bar. In order to reject new information on the ground that it is not credible, the Authority must find that the new information is not even capable of being believed; mere doubts about its reliability will not suffice.
52 Thirdly, as the appellant submitted, given the manner in which s 473DD is expressed, it would be understandable if the Authority assumed that it was unnecessary to consider new information in circumstances where it found that either the criteria in s 473DD(a) or the criteria in s 473DD(b) were not satisfied. However, it is apparent from the decision in AUS17 which post-dated the Authority's decision, that the position is more complex.
53 In AUS17, the High Court confirmed that, while paragraphs (a) and (b) of s 473DD were cumulative, the Authority must consider the criteria in subparagraphs (i) and (ii) of s 473(DD)(b) first and take its assessment of those criteria into account in considering whether the criterion in s 473(DD)(a) is met. This is because it is not possible for the Authority to determine whether there are exceptional circumstances justifying a consideration of the new information for the purposes of paragraph (a) without first addressing the criteria in paragraph (b), namely, whether the new information could have been provided (relevantly) to the delegate or is credible personal information. As Kiefel CJ, Gageler, Keane and Gordon JJ explained (at [10]-[11]):
Section 473DD would be at war with itself, and the purpose of s 473DD(b)(ii) would be thwarted, if the circumstance that there was new information from a referred applicant meeting the description in either s 473DD(b)(i) or s 473DD(b)(ii) were able to be ignored by the Authority in assessing the existence of exceptional circumstances justifying consideration of that new information in order to meet the criterion specified in s 473DD(a).
Logic and policy therefore 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)….
(Emphasis added.)
54 If the Authority failed to approach its statutory task in this manner, the majority in AUS17 held that it would not have "perform[ed] the procedural duty imposed on it by s 473DD in its conduct of a review", and the nature of the non-performance of that procedural duty may be "characterised as a failure to take account of a mandatory relevant consideration in the purported application of the criterion in s 473DD(a)": AUS17 at [12]; see also at [18].
55 In BXT17 v Minister for Home Affairs (2021) 283 FCR 248; [2021] FCAFC 9, the Full Court rejected the Minister's submission that the plurality judgment in AUS17 merely gave "guidance" on the process to be followed, holding rather that it "mandated the way in which the assessment of new information is to be undertaken pursuant to s 473DD": at [137]. It follows, therefore, that the Authority is required to "assess the new information against both criterion in s 473DD(b) and then against the criteria in s 473DD(a), taking into account any finding it makes that one or other or both of the criterion in s 473DD(b) was met": BXT17 at [140] (original emphasis). The appellant rightly submitted that the decision in BXT17 requires that a rigorous approach be taken to applying the approach required by the plurality in AUS17.
56 Finally, it was common ground that the question of whether the Authority has complied with s 473DD must be addressed as a matter of substance. It follows that, even if the Authority has not expressly referred to subsections (b)(i) and (ii) and has not expressly taken its findings on those criteria into account in considering whether the criterion in (a) is satisfied, the Court may nonetheless be satisfied, as a matter of substance, that the Authority has approached the application of the provision in this way: DDH17 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCA 1523 at [25]. Thus, as the Minister submitted, it is sufficient if it can be inferred from the Authority's reasons that the requisite assessment has occurred. As, for example, Markovic J explained in APH17 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2021] FCA 23 at [79]:
As the Minister submits, notwithstanding the plurality's statement that "logic and policy" demand that the Authority assess new information obtained from a referred applicant first against the criteria in both s 473DD(b)(i) and (ii) and only then against the criterion in s 473DD(a), it is unnecessary for the Authority to engage in any particular formulaic consideration of s 473DD(b). It will be sufficient if, in a particular case, the Court on judicial review is able to infer from the Authority's reasons that the requisite assessment has occurred. The question is whether the substance of the criteria prescribed by s 473DD(b) has been considered prior to a consideration as to whether "exceptional circumstances" exist for the purposes of s 473DD(a).
