Ground 3
32 By this ground, the applicant contends that the Assistant Minister incorrectly assumed that the existence or otherwise of non-refoulement obligations would be considered in the event that the applicant made an application for a protection visa. The applicant contends that that is not so, as the criteria for a protection visa under s 36(2) substantially differ from, and do not reflect, Australia's non-refoulement obligations.
33 This ground relies on the judgment of the Full Court of this Court in Ibrahim v Minister for Home Affairs (2019) 270 FCR 12 (Ibrahim) in relation to ground 3 in that case (considered at [87]-[119]). Ibrahim concerned an exercise of the power conferred on the Minister by s 501BA(2) of the Migration Act to set aside certain types of decisions and to cancel a visa if: (a) the Minister is satisfied that the person does not pass the character test because of the operation of s 501(6)(a) on the basis of s 501(7)(a), (b) or (c) or the operation of s 501(6)(e); and (b) the Minister is satisfied that the cancellation is in the national interest. The Full Court in Ibrahim held that the Assistant Minister had conflated Australia's non-refoulement obligations under the Convention Relating to the Status of the Refugees done at Geneva on 28 July 1951 (Refugees Convention) with the protection obligations to which the Migration Act refers and which are considered on an application for a protection visa: see [106]-[112]. The Full Court held that the error was material and accordingly that it was jurisdictional: see [115]-[116].
34 I considered a ground to the same effect in DGI19 at [69]-[85]. DGI19 concerned the power in s 501CA(4) of the Migration Act to revoke a mandatory cancellation of a visa under s 501(3A). I stated that, although Ibrahim concerned an exercise of power under s 501BA rather than s 501CA(4), the reasoning of the Full Court was, in my view, equally applicable to s 501CA(4): see DGI19 at [78]. I concluded that the Minister had conflated Australia's non-refoulement obligations under international treaties (not just the Refugees Convention) with the protection obligations to which the Migration Act refers and which are considered on an application for a protection visa: see [78]. I concluded that the Minister's misunderstanding was material and constituted a jurisdictional error: see [80], [84].
35 Although Ibrahim concerned an exercise of power under s 501BA(2) rather than s 501(2), I do not consider there to be any relevant distinction for the purposes of this ground between s 501BA(2) and s 501(2). Likewise, I do not consider there to be any relevant distinction between s 501CA(4) and s 501(2) for the purposes of this ground. It was necessary for the Assistant Minister to have a correct understanding of the Migration Act when exercising the power in s 501(2) to cancel the applicant's visa. This principle applies, not only to the formation of a state of satisfaction, but also to the exercise of a statutory discretion: see Re Patterson; Ex parte Taylor (2001) 207 CLR 391 at [196] per Gummow and Hayne JJ (with whom Gleeson CJ agreed); Graham v Minister for Immigration and Border Protection (2017) 263 CLR 1 at [57], [68] per Kiefel CJ, Bell, Gageler, Keane, Nettle and Gordon JJ. See also Steyn v Minister for Immigration and Border Protection [2017] FCA 1131 at [11], [16] per Jagot J. There does not appear to be any dispute between the parties on this point. In his additional submission dated 23 March 2020, the Minister stated that he "does not contend that if he misunderstands the Act or its operation in a way that materially bears on the exercise of the Minister's discretion under s501(2), that would not amount to jurisdictional error".
36 The reasoning of the Assistant Minister in the present case (see [28] above) is very similar to the reasoning of the Assistant Minister in Ibrahim (see Ibrahim at [66]-[67]) and substantially the same as the reasoning of the Minister in DGI19 (see DGI19 at [30]).
37 In my view, in the present case, the Assistant Minister conflated Australia's non-refoulement obligations under international treaties (not just the Refugees Convention) with the protection obligations to which the Migration Act refers and which are considered on an application for a protection visa. The five matters to which I referred in DGI19 at [78] are equally applicable in the present case (in this case, the particular paragraphs of importance are [41] and [45] of the Assistant's Minister's statement of reasons, set out at [28] above). Thus, for substantially the same reasons as set out in DGI19 (particularly at [78]-[79]), I consider that the Assistant Minister in the present case proceeded on the basis of the misunderstanding alleged by the applicant. The Assistant Minister's belief involved a misapprehension as to the effect of the Migration Act.
38 For the applicant's ground to succeed, it is necessary for him to establish that the misunderstanding was material. The applicable principles relating to materiality are set out in Hossain v Minister for Immigration and Border Protection (2018) 264 CLR 123 at [28]-[31] per Kiefel CJ, Gageler and Keane JJ; and Minister for Immigration and Border Protection v SZMTA (2019) 264 CLR 421 at [45]-[46] per Bell, Gageler and Keane JJ.
39 In Ibrahim, the Full Court was satisfied that the Assistant Minister's error was material "given the potential for the internal relocation principle to be applied in the appellant's circumstances": see [115]. The context for this conclusion was as follows. Earlier in the Full Court's judgment, at [66], the Full Court set out an extract from the Assistant Minister's reasons that referred to the appellant's representative's submissions. These included a submission that the appellant's family was from northern Nigeria and that Christians in northern Nigeria had been targeted by the fundamentalist group Boko Haram. The Full Court discussed, at [95], a difference between the protection criteria under the Migration Act and the criteria under the Refugees Convention as regards the internal relocation principle. The Full Court stated that s 5J(1)(c) "has the effect of removing the internal relocation principle from consideration in an application for protection under s 36(2)(a)". The Full Court also noted, at [96], the appellant's submission that the internal relocation principle was potentially relevant "because of the claim that the appellant has a well-founded fear of persecution in the north of Nigeria". In the context of these matters, the Full Court concluded, at [115], that the Assistant Minister's error was material.
40 In DGI19, I concluded that the Minister's error was material because there was the possibility that if the Minister had not made the error he would have considered the representations relating to non-refoulement obligations and come to a different conclusion: at [80]. Further, at [84], I considered a submission by the Minister that the factual circumstances of DGI19 were distinct from those in Ibrahim because in Ibrahim internal relocation principles could have potentially had a bearing on the existence of non-refoulement obligations in respect of the appellant, whereas (the Minister submitted) on the facts of DGI19 no issue of internal relocation would or could properly arise on the basis of the applicant's representations. I expressed the view that these matters did not provide a basis for distinguishing Ibrahim and gave three reasons. First, as stated in [80], I considered that the misunderstanding as to the operation of the Migration Act was material because there was the possibility that if the Minister had not made the error he would have considered the representations relating to non-refoulement obligations and come to a different conclusion. Secondly, I considered that it was not incumbent on an applicant proleptically to deal with the possibility of relocation. Thus, there was the potential for the application of the principle in DGI19. Thirdly, I stated that Parliament's decision not to reflect the "internal relocation principle" in the visa criterion in s 36(2)(a) was not the only respect in which there was a substantial divergence between the content of Australia's non-refoulement obligations and the protection visa criteria. Another example was Parliament's decision to require an applicant to satisfy the decision-maker that a person has a specific "intention" to cause him or her certain kinds of harm in order to satisfy the visa criterion in s 36(2)(aa), referring to SZTAL v Minister for Immigration and Border Protection (2017) 262 CLR 362 at [4]-[5].
41 In oral submissions, counsel for the applicant submitted that there is a realistic possibility that, if the Assistant Minister had not had the misunderstanding, he might have made a different decision. Counsel submitted that: (a) but for the misunderstanding, the Assistant Minister might have decided to assess whether or not non-refoulement obligations were owed; (b) if the Assistant Minister decided to assess whether such obligations were owed, he might have decided that they were owed in respect of the applicant (including by reference to further enquiries); and (c) if the Assistant Minister assessed that non-refoulement obligations were owed, he might have decided not to cancel the applicant's visa. Counsel relied on Gill v Minister for Immigration and Border Protection (2017) 250 FCR 309 at [97]-[100] and DHS17 v Assistant Minister for Immigration and Border Protection (2018) 267 FCR 411 at [39], [63]-[64]. In the applicant's supplementary submissions dated 10 July 2020, he relies on the judgment of the Full Court in Ali at [104], [111] and [118], where the Full Court concluded that the errors in that case were material.
42 The Minister submits that, in light of the substance of the representations that were made (which did not rely on Australia's non-refoulement obligations), even if (contrary to the Minister's submissions) the Assistant Minister proceeded on a misunderstanding of the kind found in Ibrahim, it was not a material error, in the sense that there was not a realistic possibility that the Minister's decision could have been different had consideration to been given to non-refoulement obligations. The Minister submits that the internal relocation principle, which was relevant in Ibrahim, was not relevant; nor is it shown that any further misunderstanding was relevant.
43 In my view, the Assistant Minister's error was material because there is a realistic possibility that if the Assistant Minister had not made the error he would have considered the submissions relating to non-refoulement obligations and, in that event, he may have come to a different conclusion. It is true that there are factual differences between the present case and DGI19. In particular, in DGI19, the applicant (including through his representatives) made detailed submissions that referred in terms to Australia's non-refoulement obligations. In contrast, in the present case, the applicant did not refer in terms to Australia's non-refoulement obligations and the relevant submissions (and supporting material) were relatively brief. However, it is relevant to take into account that the applicant in the present case did not have legal representation at the time he made his submissions. Further, the Assistant Minister in the present case expressly recognised (in the statement of reasons at [40]) that the applicant's claims "may give rise to international non-refoulement obligations". It is also true that the applicant's submissions to the Assistant Minister did not identify a particular relevant difference between international non-refoulement obligations and the criteria for a protection visa (such as the internal relocation principle). However, for the reasons I gave in DGI19 at [84] (cf. Ali at [116]) and those given in Ali at [117], I consider that the error was nevertheless material. In the circumstances, there is a realistic possibility that, if the Assistant Minister had not made the error, he would have considered whether non-refoulement obligations were owed in respect of the applicant. Had he done so, he may have come to a different conclusion.
44 The applicant's third ground is therefore made out.
45 In light of my conclusion in relation to ground 3, it is unnecessary to consider the remaining grounds. However, I make the following observations about those grounds.
