Merits of the proposed ground of challenge
27 By the draft originating application that he proposes to file if granted an extension of time to do so, the applicant mounts a single ground of challenge against the Tribunal's Decision, namely that:
In purporting to discharge its function, the Tribunal constructively failed to exercise its jurisdiction by its failure to consider the Applicant's request for revocation of the cancellation of his Global Special Humanitarian visa against the correct country of nationality and/or country to which the Applicant would be returned.
28 By the written submissions advanced on his behalf, the applicant elaborated upon that ground as follows:
The proposed ground is put in two overlapping ways: [f]irst, the Tribunal failed to consider the Applicant's claims that he would be harmed on return to his country of nationality to the relevant legal standard; [and] second, the Tribunal failed to make an obvious enquiry about the Applicant's nationality, a fact which was of central criticality to the outcome of the review.
29 Two things should be recalled from the factual summary recited earlier: first, that the applicant's Revocation Request proceeded upon the basis that "another reason" for which the Minister ought to revoke the Cancellation was that it was not safe for the applicant to be returned to Sudan; and, second, that the applicant was not, in fact, Sudanese (and had mistakenly stated that he was).
30 With those circumstances recalled, the first of the two overlapping ways in which the applicant's proposed challenge is framed can swiftly be addressed. It is not in doubt that the Tribunal was obliged to consider the claims that the applicant advanced as to why the Cancellation ought to be revoked: Minister for Home Affairs v Omar (2019) 272 FCR 589, 602-604 [34] (Allsop CJ, Bromberg, Robertson, Griffiths and Perry JJ); DQM18 v Minister for Home Affairs [2020] FCAFC 110, [23]-[34] (Bromberg and Mortimer JJ), [153]-[158] (Snaden J); Navoto v Minister for Home Affairs [2019] FCAFC 135, [86]-[89] (Middleton, Moshinsky and Anderson JJ); Minister for Home Affairs v Buadromo (2018) 267 FCR 320, 332 [42] (Besanko, Barker and Bromwich JJ). But equally, the Tribunal was not required to consider, as a reason in favour of revocation, a circumstance that the applicant in fact did not put: Minister for Immigration and Border Protection v BHA17 (2018) 260 FCR 523, 547-548 [79]-[80] (Robertson, Moshinsky and Bromwich JJ); Minister for Immigration and Citizenship v Le (2007) 164 FCR 151, 172 [60] (Kenny J). A claim that emerges from an applicant's submissions only with the assistance of "constructive or creative activity" on the part of a decision-maker is not one of which consideration is mandatory: NABE v Minister for Immigration and Multicultural and Indigenous Affairs (2004) 144 FCR 1, 19 [58] (Black CJ, French and Selway JJ).
31 The applicant identified himself as Sudanese and claimed that the risk or risks to which he would be subjected if returned to Sudan were "another reason" (or reasons) why his Cancellation ought to be revoked. Those contentions - mistaken though they were - were, on any view, considered and addressed. The mistake was not of the Tribunal's making: it considered what it was asked to consider. There was no jurisdictional error in its doing so.
32 Attention should then turn to the second of the two overlapping ways in which the applicant grounds the challenge that he seeks to make. He maintains that the Tribunal ought to have realised his error: that it ought to have been apparent that, contrary to what he submitted, the applicant was not Sudanese and was not at risk of being returned to Sudan. Had that reality been identified, the Tribunal would have invited further submission from the applicant about any concerns that he might have had about being returned to South Sudan, which it would then have assessed in the usual way (and, more particularly, by considering whether they gave rise, by themselves or in combination with other factors, to "another reason [or reasons]" for the purposes of s 501CA(4)(b)(ii) of the Act). The applicant submits that, had those events transpired, the Tribunal might well have decided the Review Application differently.
33 At issue presently, then, is whether the Tribunal was obliged to recognise and correct the applicant's error. In urging the court to answer that question in the affirmative (or, in the context of the immediate application, to find that there is a sufficient prospect of an affirmative answer), the applicant relied upon the following observations of the majority (French CJ, Gummow, Hayne, Crennan, Kiefel and Bell JJ) in Minister for Immigration and Citizenship v SZIAI (2009) 83 ALJR 1123, 1129 [25]:
…The duty imposed upon the tribunal by the Migration Act is a duty to review. It may be that a failure to make an obvious inquiry about a critical fact, the existence of which is easily ascertained, could, in some circumstances, supply a sufficient link to the outcome to constitute a failure to review. If so, such a failure could give rise to jurisdictional error by constructive failure to exercise jurisdiction. It may be that failure to make such an inquiry results in a decision being affected in some other way that manifests itself as jurisdictional error…
(emphasis added)
34 There are authorities in this court that recognise that same obligation: Ashraf v Minister for Immigration and Border Protection (2018) 261 FCR 97, 115 [56]-[57] (Tracey, Mortimer and Moshinsky JJ); Nguyen v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs & Anor [2020] FCA 985, [53] (Mortimer J).
35 Here, the applicant submits that the Tribunal's obligation to incorporate into the discharge of its review function an inquiry as to his true nationality arose from evidence that he gave about his place of birth and the fact that, as he testified, he "[didn't] know anything about Sudan". In his Revocation Request, the applicant noted that he was born in "Juba Sudan". In 1981, when the applicant was born, Juba was a city of Sudan. It is now the capital of South Sudan. It should, the applicant submits, have been apparent to the Tribunal that his nationality was not beyond question; and that ought, he says, to have inspired the Tribunal to make further inquiries on that front in the proper discharge of its statutory review function. If that is so, the Tribunal's failure to make those inquiries would amount to a failure to discharge the function that it was required to discharge; and its ultimate decision not to revoke the Cancellation would be amenable to prerogative relief as the product of jurisdictional error.
36 The fact that the applicant was born in Juba was not something that ought to have prompted the Tribunal to question or disbelieve what he said about being Sudanese. It was common ground between the parties (and the court was taken to legislation that reflected the fact) that South Sudanese citizenship was not dependent upon, or even a function of, a person's having been born in what is now South Sudan. Similarly, the applicant's statement that he didn't know anything about Sudan was not sufficient to warrant the Tribunal's forming the view that he might mistakenly have nominated Sudan as his country of citizenship. It is one thing to disclaim a lack of knowledge about one's country of citizenship; quite another to suggest that there might be some confusion about which country that is.
37 Those things having been said, I do not accept that it ought to have been obvious to the Tribunal that, despite his evidence, the applicant's nationality was a matter that required further inquiry, nor that the Tribunal's failure to embark upon that inquiry bespeaks any want of compliance with its statutory charter. With respect, the applicant's prospects of successfully agitating his proposed challenge to the Tribunal's Decision are poor.
