Setting aside order
13 As to the setting aside order, the Minister contends grant of certiorari was not "on the cards" at the hearing and the appellant did not seek it. If it had been raised, the Minister would have made submissions that such relief was not appropriate and drawn the Court's attention to what the Minister submits is the binding authority of Plaintiff M61/2010E v Commonwealth [2010] HCA 41; 243 CLR 319 against the grant of such relief. The Minister relies on the decision of Gilmour J in Construction, Forestry, Mining and Energy Union v Mammoet Australia Pty Ltd (No 2) [2012] FCA 1404; 209 FCR 123 (CFMEU) at [10] to the effect that the slip rule in r 39.05(e) of the Federal Court Rules 2011 (Cth) can be invoked in circumstances where there was a failure for the issue of an order setting aside the decision of the second respondent to be raised with the parties before such an order was made. In the CFMEU case, Gilmour J was dealing with a costs order and concluded he was "confident that the order would not have been made", had the issue been fully addressed during the hearing.
14 The appellant is correct to submit, responsively, that the order setting aside the decision of the second respondent was not a mistake or a slip. The Court intended to grant that relief. It did not grant a writ of certiorari: see generally the discussion about where the Federal Court's power to grant writs comes from in the Full Court decision of McHugh v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCAFC 223; 385 ALR 405 at [3], [20], [77] and [187].
15 In Plaintiff M61, a writ of certiorari was in issue because the High Court's jurisdiction arose under s 75(v) of the Constitution. The Federal Court has power to grant writs, but it also has much wider statutory powers to make orders of such kinds as the Court thinks appropriate: see Federal Court of Australia Act 1976 (Cth) s 23. In the exercise of that power, it can make an order setting aside a decision where that decision affects the rights or interests of a person.
16 The decision or recommendation of the second respondent affects, in my opinion, at least the interests of the appellant. The non-statutory executive process to which the appellant was subjected was the only process offered to him after he was detained on arrival in Australia. It was his pathway to being able to make a claim for protection under Australia's visa system. It was his only pathway out to regain his freedom and remain in Australia. A negative decision such as the decision made by the second respondent precluded the appellant from advancing any further down that pathway.
17 In Plaintiff M61, certiorari was not granted because, under the traditional principles applicable to that writ, it could only be granted in aid, or it should only have been granted in aid, of the grant of mandamus, and mandamus was not available. The situation is not identical here, as the Court has not purported to grant certiorari and has not purported to remit anything with or without an order of mandamus to the second respondent.
18 However, the Court was informed at the hearing that on 26 October 2021 the appellant's request for an exercise of the power under s 46A of the Migration Act 1958 (Cth) had been "internally remitted" and will be reassessed by someone within the Department with the appropriate delegation. The Court was also informed that no removal of the appellant will be considered while that process is underway. The process was explained to the Court as an internal non-statutory process for which there are some administrative guidelines.
19 As I noted during the hearing, there is no need for the Court to engage in detailed and perhaps contested legal analysis about whether the set aside order was available and appropriate where the ultimate objective might be secured in a less contested way. In his notice of appeal to this Court, one of the orders sought by the appellant was that the Minister be restrained from relying on the second respondent's recommendation. Counsel for the Minister appeared to accept relief of that kind could be granted, although he submitted it was not necessary. In my opinion, relief of that kind is available: see Smethurst v Commissioner of Police [2020] HCA 14; 376 ALR 575 at [170]-[183] in the reasons of Gordon J. On balance, I have concluded that injunctive relief is the preferable kind of order. There will be a variation to the Court's orders of 28 September 2021 to that effect.
20 While I accept that the Minister will respect a declaration made by the Court, I am not confident the subject matter of the declaration is sufficiently clear, especially to a delegate or person charged with conducting a reassessment, that no further or other order should be made. I emphasise, therefore, that the injunction is granted for the sake of clarity, to make it clear that, as the Court explained in its reasons of 28 September 2021, the denial of procedural fairness was critical and material to the way the second respondent assessed the credibility of the appellant, and so in that sense the whole task of the second respondent miscarried. That is why it is appropriate to restrain the Minister, and her employees, officers and agents, from giving any effect to the second respondent's recommendation. That does not preclude a fresh reviewer having regard to the material that was before the second respondent in the conduct of a fresh review.
21 For these reasons, I accept that there was some purpose in the Minister's interlocutory application, and it would not be appropriate for that interlocutory application to be dismissed. However, the relief sought in the interlocutory application should be refused. As to the costs of the hearing today, it is somewhat difficult to understand that the appellant's legal representatives have not been informed about the 26 October 2021 internal remitter, and at least a significant part of today's hearing has been taken up with refinements made to the parties' arguments and positions and an adjournment all because of this new development, of which apparently only the Minister, her department and her legal representatives seem to be aware. Accordingly, in my view, the appellant should have his costs of the hearing today, but not the costs associated with responding to the interlocutory application.
