The jurisdiction of the Tribunal
41 To address whether the Tribunal was not required to separately consider the complementary protection criterion in s 36(2)(aa), it is necessary to first say a few things about the nature of the Tribunal's jurisdiction in this case, by reference to the Migration Act.
42 The Migration Act creates a bifurcated system of merits review. A decision by the Minister to refuse to grant a protection visa is reviewable by the Tribunal under two separate sources of power. The first is conferred under Part 7 of the Migration Act and the second is conferred under s 500.
43 Section 414 of the Migration Act confers upon the Tribunal jurisdiction to review "Part 7 Reviewable Decisions". The term "Part 7 Reviewable Decision" is defined in s 411(1)(c) as a decision to refuse to grant a protection visa other than a decision that was made relying on s 5H(2), s 36(1B), s 36(1C) or s 36(2C). Reviews of "Part 7 Reviewable Decisions" are heard, and can only be heard, by the Tribunal's Migration and Refugee Division: s 409(2) of the Migration Act. Part 7 has detailed provisions concerning the manner in which the Tribunal is to review "Part 7 Reviewable Decisions", which include a power for the Minister to substitute a decision that is more favourable to the applicant if the Minister thinks it is in the public interest to do so: s 417.
44 Conversely, subject to an exception not presently relevant, s 500(1)(c) vests in the Tribunal jurisdiction to review a decision under s 65 of the Migration Act to refuse to grant a protection visa relying upon s 5H(2), s 36(1C) or s 36(2C). Such reviews are conducted by the General Division of the Tribunal according to the procedures applicable under the Administrative Appeals Tribunal Act 1975 (Cth) (AAT Act) as modified by s 500 of the Migration Act: see simplified outline in s 408 of the Migration Act.
45 It is to be noted that under the terms of the AAT Act, a member of the Tribunal "may exercise, or participate in the exercise of, powers of the Tribunal only in a Division to which the member is assigned": s 17C(4). Before assigning a member to the Migration and Refugee Division, the responsible Minister must consult the Minister administering the Migration Act in relation to the proposed assignment: s 17D.
46 In Daher, at 110-111 the Full Court explained the bifurcation of the review functions of what were then the Refugee Review Tribunal and the Administrative Appeals Tribunal:
In the present case, it is an object of the [Migration] Act that reviews of decisions taken under art. 1F of the Convention shall be conducted by the Administrative Appeals Tribunal. That object is not merely to be inferred from the Act. The Act makes it explicit by conferring jurisdiction upon the Administrative Appeals Tribunal and by excluding review under Part 7 of the Act.
…
The Act has, therefore, notionally divided decisions refusing to grant a protection visa into two distinct parts, namely, those parts constituting refusal in reliance on Arts 1F, 32 or 33(2) of the Convention and those relying on other aspects of the Convention, particularly Art 1A(2). Accordingly, in s 411(1)(c), the term "a decision to refuse to grant a protection visa" must be read as excluding such a decision insofar as it relies upon Arts 1F, 32 or 33(2) of the Convention. The Act makes this explicit by providing in s 500(4) that the excluded decisions are not reviewable under Part 7 of the Act, in which s 411 appears.
It follows that the only decision which the Refugee Review Tribunal had jurisdiction to review was a decision which did not rely upon Arts 1F, 32 or 33(2). It was only for the purpose of reviewing that limited decision, the elements of which were within its jurisdiction, that the Refugee Review Tribunal was authorised to exercise all the powers and discretions that were conferred by the Act on the person who made the decision. As the question whether Mr Daher fell within the terms of Art 1F was not an issue within the ambit of the decision which the Refugee Review Tribunal had jurisdiction to review, the Refugee Review Tribunal had no cause to enter into that question for the purposes of the review of the decision.
47 Although there have been amendments to the Migration Act since Daher, given the relevant provisions in the Migration Act described above, the bifurcation of merits review described in Daher continues under the Migration Act in its current form: see also Hamidy v Minister for Immigration and Border Protection [2019] FCA 221 at [31]-[33].
48 Accordingly, as the delegate's decision was made in reliance on the Serious Crime Exclusion in both s 5H(2) and s 36(2C)(a)(ii) of the Migration Act, the Tribunal's decision was made in its General Division. We agree with the primary judge's finding that although the delegate found that the complementary protection criterion in s 36(2)(aa) was not satisfied, the decision was also made in reliance on s 36(2C) because the delegate found that the Serious Crime Exclusion would apply. We endorse what his Honour said at [23] of the Primary Judgment, namely:
As to complementary protection the outcome also relied upon the finding that there was not a real risk of significant harm. Any claim that the consequence was that the Serious Crime Exclusion was not 'relied upon' as to complementary protection for the purposes of determining the pathway for review should not be accepted because it would be inconsistent with the bifurcated structure. It would produce the prospect of concurrent reviews, one in the General Division and one in the Migration and Refugee Division. For that reason, following the approach in Daher, if any part of the decision on the application for a protection visa relied upon the Serious Crime Exclusion provisions then review must be sought in the General Division.
(emphasis added)
49 The appellant does not challenge the correctness of Daher, but places a different interpretation on it, submitting that it does not address the issue at hand in this case. That is, although there is a bifurcation structure, once the matter is to be heard in the General Division, it is to be dealt with according to the AAT Act, in particular s 43. That is, relevantly to this case, the review is not limited to the Serious Crime Exclusion: see [20] above. However, s 43 provides relevantly, that "[f]or the purpose of reviewing a decision, the Tribunal may exercise all the powers and discretions that are conferred by any enactment on the person who made the decision". Section 43 does not enlarge or confer the Tribunal's jurisdiction. As the respondent submitted, where, as here, the jurisdiction to review was bifurcated in the way that it was, s 43 could not overcome that statutory regime, here, the regime specific to the Migration Act. If s 500(1)(c) of the Act is considered in isolation, it may be possible to read the conferral of jurisdiction to review a decision 'relying on' the Serious Crime Exclusion as a conferral of jurisdiction to review every aspect of that decision, not just the Serious Crime Exclusion aspects. But the legislative context and history we have outlined show that this reading would be incorrect.
50 It is also appropriate to address the appellant's reliance on Shi, Nathanson and Frugtniet. In short, properly read, these cases do not support a contrary view. They do not support the proposition that the Tribunal must ask itself the same questions that the primary-decision maker did ask itself in circumstances where the Tribunal's jurisdiction has been limited, if not expressly, then by necessary implication as we have described.
51 Shi was concerned with the nature of administrative review and whether the Tribunal was limited to considering the state of affairs existing at the time of the decision under review. In that context, the respondent contended that the Tribunal's role was to determine whether the original decision was erroneous. Kiefel J (as her Honour then was), held that reviewing the reasons for a decision (including for the purposes of identifying error) would not fulfil the Tribunal's function. The Tribunal would instead need to stand in the shoes of the original decision-maker: see especially at [134]-[135]. Such powers are not consistent with a role limited to ascertainment of error.
52 As the respondent submitted, Shi does not stand for the proposition that any review by the Tribunal must be on the same terms or directed to the same issues as were before the original decision-maker in circumstances where the Tribunal's jurisdiction has been limited by the Migration Act. It says nothing about the authority of the legislature to confer a right of review, whether at large or on terms, to the Tribunal.
53 Nathanson at [7] similarly stands for the proposition that the Tribunal was required to stand in the shoes of the original decision maker having regard to the state of affairs as it stood at the time of the Tribunal's decision. Like Shi, Nathanson says nothing about the Tribunal being required to approach the reasoning process in the same way as the original decision-maker.
54 In the same vein, the passage in Frugtniet at [51] on which the appellant relies, says nothing about the Tribunal being obligated to approach the reasoning process in the same way as the original decision-maker. The appellant's reliance on [51] must be considered in context, as he omits the first sentence of the paragraph:
…except where altered by some other statute, which has not occurred here, the jurisdiction conferred on the AAT by ss 25 and 43 of the AAT Act, where application is made to it under an enactment, is to stand in the shoes of the decision-maker whose decision is under review so as to determine for itself on the material before it the decision which can, and which it considers should, be made in the exercise of the power or powers conferred on the primary decision-maker for the purpose of making the decision under review.
(emphasis added)
55 The primary judge concluded at [24]:
It follows that I accept the submission for the Minister that, by reason of the bifurcation, the required course is for the applicant to seek review under s 500(1)(c) in the General Division of the Tribunal. Further, in such a case, the jurisdiction of the General Division is confined to reviewing the decision to refuse the application for a protection visa to the extent that reliance was placed by the decision maker upon the Serious Crime Exclusion. The procedures of the General Division (as modified by s 500 of the Migration Act) apply to the exercise of the jurisdiction. Otherwise, the structure by which members of the Tribunal are appointed to the Migration and Refugee Division and the different statutory regime to deal with other aspects of applications to review protection visa applications would be compromised.
56 As referred to above at [11], the primary judge accordingly concluded at [26]:
…there could be no error in the Tribunal when sitting in its General Division failing to consider the aspects of the complementary protection criterion that did not concern the Serious Crime Exception. Review of that aspect was outside its jurisdiction. However, it was obliged to consider whether the Serious Crime Exception applied to complementary protection.
57 The Minister accepts the correctness of the primary judge's reasons. The appellant has not established any error in that conclusion.
58 Nevertheless, given that the Tribunal did not turn its mind to and consider separately whether the Serious Crime Exclusion applied to complementary protection, it must follow that it erred to that extent. However, that does not mean that the Tribunal did not consider, as a matter of fact and substance, whether the Serious Crime Exclusion applied to the circumstances of the applicant's case on review. Thus, the matter comes down to materiality, to which we now turn.
