The Primary Judge's Decision
19 The primary judge's reasons refer to various authorities concerning the obligation of the Tribunal to consider the prospect of a person who had a visa refused, or cancelled on character grounds under s 501 of the Act, being the subject of prolonged or indefinite detention. His Honour's discussion of that obligation, and the circumstances in which it may arise, ultimately had no bearing on the outcome of the case because his Honour accepted that the Tribunal was required to give consideration to the appellant's claim that, unless the cancellation was revoked, he would remain in detention, in counsel for the appellant's words, until the Minister decided what to do with him, which could take a very long time, possibly years.
20 Relevant extracts from the appellant's submissions to the Tribunal are reproduced at [17] of the primary judge's reasons. The appellant's written submissions to the Tribunal included the following:
83. So, in practical terms, if non-refoulement obligations are owed in respect of the application, unless those obligations cease to be owed (which is not realistic in the case of Hazaras from Afghanistan), the application will have to be released into the community eventually.
84. These processes can take some time. It might be years. All the while the applicant sits in detention, costing the taxpayer dearly; more than $300,000 per year. One might thus ask, what is the point of keeping the applicant in detention throughout this period, at a very substantial cost to the taxpayer (equivalent to about 10 JobKeeper payments per month)? Is the risk that the applicant poses worth $300,000+ per year in tax-payers' money, when he will probably be released into the community anyway, some years into the future.
21 As the primary judge noted, the appellant's submissions to the Tribunal in relation to indefinite detention were predicated on two assumptions, first, that the appellant would not be returned to Afghanistan and, second, that he would not be granted a protection visa.
22 The primary judge said at [42]-[46]:
[42] The applicant's submissions to the Tribunal regarding indefinite detention were predicated on the assumption that the applicant would not be returned to Afghanistan, and that he would not be granted a protection visa. In other words, those two factual propositions underpinned the applicant's submission that he faced the prospect of indefinite detention. On that footing, the thrust of the submissions was that it would be futile for the applicant to remain in detention for an indefinite period at significant public cost. But, as the Tribunal recognised, there were other possibilities: the applicant could be removed to a third country, or the applicant could request or make an application for ministerial intervention under s 195A or s 197AB of the Act. The Tribunal's Decision engaged with each of those eventualities and the reality that the applicant would be detained while they were being explored.
[43] Contrary to what the applicant urged upon it, the Tribunal found that the applicant's prospects of being granted a protection visa were "not implausible". It did not accept the factual proposition that the applicant would not be returned to Afghanistan. Instead, it observed that the applicant's "concerns about refoulement are minimised by the Australian Government's express policy commitment not to do so". The Tribunal also noted that there was no evidence "that any exercise of [ministerial] discretion is currently in prospect", and that "[t]here is also no evidence that removal to any other country may be in prospect".
[44] Critically, the Tribunal acknowledged that, "[i]n the event of a non-revocation decision, [the applicant] is liable to be detained under s 189 of the Act following release from prison and is liable for removal as soon as reasonably practicable" and that it "is permissible to continue a person's detention" while consideration is given to ministerial intervention. In other words, the Tribunal engaged with the fact that the applicant would enter immigration detention following his release from prison, and would remain there while available options (of which the Tribunal noted there were several) were explored. The Tribunal also declined to speculate about the potential course of future decision making, and the potential cost of immigration detention yet to occur, which matters were central to the applicant's submission that his ongoing detention would be futile.
[45] Those realities acknowledged, I do not accept that the Tribunal can fairly be said to have made its decision without first considering what the applicant advanced. A finding that a minister "…has not engaged in an active intellectual process will not lightly be made and must be supported by clear evidence, bearing in mind that the judicial review applicants carry the onus of proof": …
[46] At its core, the applicant's complaint is that the Tribunal did not, in terms, record what is obvious: namely, that the period for which the applicant might remain in immigration detention will be a function of multiple variables, many (and probably most, if not all) of which do not permit of anything more than bald conjecture. Plainly, he might remain in immigration detention for a lengthy period of time whilst those variables play themselves out. He might not: it might be years; it might be weeks. Regardless, it cannot be said that the Tribunal was not alive to - that is to say, failed to consider - that detention would remain in play for so long as those processes took to resolve. Engagement in a process of active intellectual consideration is one thing; engagement in a process of speculation is something else entirely.
