Whether the Tribunal denied the appellant procedural fairness or acted unreasonably
31 Section 39(1) of the Administrative Appeals Tribunal Act 1975 (Cth) (AAT Act) requires the Tribunal to ensure that every party to a proceeding before it is given a reasonable opportunity to present his or her case. That requirement is also at the heart of the obligation to afford natural justice which the law would in any event imply: Sullivan v Department of Transport (1978) 20 ALR 323 at 342 (Deane J, Fisher J agreeing). A failure to accede to a reasonable request for an adjournment can constitute procedural unfairness: Minister for Immigration and Multicultural Affairs v Bhardwaj [2002] HCA 11; (2002) 209 CLR 597 at [40] (Gaudron and Gummow JJ, citing Sullivan at 343).
32 What is reasonable will depend upon the circumstances of the case: Re Australian Railways Union; Ex parte Public Transport Commission (1993) 117 ALR 17 at 24. However, the duty of the Tribunal was to afford the applicant a reasonable opportunity to present his case, not the best possible opportunity that the Tribunal may have been capable of accommodating, or an adjournment to 'a date as late as humanly possible': Daw v Minister for Immigration & Citizenship [2012] FCA 705 at [25], [30] (Edmonds J), affirmed in Daw v Minister for Immigration and Citizenship [2012] FCAFC 123 (Flick, Nicholas and Robertson JJ). As that case illustrates, the question of whether or not an applicant has been given a reasonable opportunity to be heard depends on the course of the proceedings as a whole: see especially [2012] FCA 705 at [24], quoted with approval in [2012] FCAFC 123 at [11].
33 The withdrawal of legal representation shortly before a hearing does not mean that a court will always grant an adjournment in the proper exercise of its discretion. Each case depends on the individual circumstances: Jarrett v Westpac Banking Corporation [1999] FCA 425 at [87] (Mansfield J). While Jarrett concerned adjournment of court proceedings, there is no reason to suppose that an administrative tribunal is more likely to be required to grant an adjournment in those circumstances.
34 Apart from procedural fairness, the law is also clear that a refusal to grant an adjournment may be set aside where it is shown to be legally unreasonable in the sense that the refusal was without 'an evident and intelligible justification': Minister for Immigration and Citizenship v Li [2013] HCA 18; (2013) 249 CLR 332 at [76], [82], [85] (Hayne, Kiefel and Bell JJ).
35 It is not necessary for Mr Khalil to establish that adjourning for only 24 hours was irrational or bizarre, or was a decision that no reasonable decision maker could have made: Li at [68] (Hayne, Kiefel and Bell JJ). Nevertheless, the standard is a stringent one: Li at [113] (Gageler J); Minister for Immigration and Border Protection v SZVFW [2018] HCA 30; (2018) 357 ALR 408 at [11] (Kiefel CJ), [52], [70] (Gageler J), [135] (Edelman J). In TTY167 v Republic of Nauru [2018] HCA 61; (2018) 362 ALR 246 at [24] the High Court observed that the standard is particularly demanding in light of concerns, including informality and the need for efficiency, that underlay hearings of the Refugee Status Review Tribunal of Nauru. That observation is apposite to the Administrative Appeals Tribunal and the latitude it has to decide whether to adjourn a hearing. The task is not for this court to determine what it thinks was reasonable in the circumstances and thereby conclude that any other view displays error: Minister for Immigration and Border Protection v Stretton [2016] FCAFC 11; (2016) 237 FCR 1 at [12] (Allsop CJ). It would be a rare case to find that the exercise of a discretionary power was unreasonable where the reasons demonstrated a justification for that exercise of power: SZVFW at [84].
36 It is clear that Mr Khalil was placed in a very difficult position through no fault of his own. There was no suggestion that the Minister would have been prejudiced by an adjournment longer than the 24 hours that was given. It is hard to see what Mr Khalil could have accomplished in that short period of time, especially in detention on Christmas Island, and in circumstances when he did not have any of the relevant documents at the time the adjournment was granted. If the assumed effect of s 500(6L) of the Migration Act were to be disregarded, it is clear that it would have been unreasonable for the Tribunal to have granted such a short adjournment.
37 However, in our view it is not necessary to engage with the difficult questions of evaluation that are raised by the above principles, as there is a more straightforward path of reasoning which leads to a finding of jurisdictional error here. The argument was not put to the primary judge. But when it was raised at the hearing of the appeal, the Minister did not object to it being considered and sought, and was granted, the opportunity to file supplementary written submissions.
38 In Minister for Immigration and Border Protection v Singh [2014] FCAFC 1; (2014) 231 FCR 437 at [44] the court pointed out that legal unreasonableness can be employed in two different contexts. One focusses on the outcome of the decision and seeks to characterise it as unreasonable, even though made within 'an area of decisional freedom' conferred by the statute. But legal unreasonableness can also arise where a more specific jurisdictional error has been identified: see Li at [28] (French CJ), [72] (Hayne, Kiefel and Bell JJ). For the following reasons, we consider that the Tribunal fell into an error of that kind here.
39 It is plain from the extracts from the transcript of the hearing quoted above that the Tribunal was proceeding on the basis that not only did it have to deliver its decision on the review by Monday 26 February 2018, but it also needed to provide written reasons by that time. That is particularly clear from the passage from the transcript of the hearing on 20 February 2018 in which the Deputy President said that he would be 'delivering a written decision which will set out all the facts and the considerations, so he will get a written decision, and that has to be by next Monday'. The Tribunal equated the requirement that it make a decision by the following Monday with the requirement that it produce written reasons for the decision.
40 The Tribunal was incorrect to proceed on that basis. The provisions relevant to delivery of reasons in s 43 of the AAT Act are as follows:
Tribunal must give reasons for its decision
(2) Subject to this section and to sections 35 and 36D, the Tribunal shall give reasons either orally or in writing for its decision.
(2A) Where the Tribunal does not give reasons in writing for its decision, a party to the proceeding may, within 28 days after the day on which a copy of the decision of the Tribunal is given to that party, request the Tribunal to give to that party a statement in writing of the reasons of the Tribunal for its decision, and the Tribunal shall, within 28 days after receiving the request, give to that party such a statement.
(2B) Where the Tribunal gives in writing the reasons for its decision, those reasons shall include its findings on material questions of fact and a reference to the evidence or other material on which those findings were based.
…
When Tribunal's decision comes into operation
(5A) Subject to subsection (5B), a decision of the Tribunal comes into operation forthwith upon the giving of the decision.
(5B) The Tribunal may specify in a decision that the decision is not to come into operation until a later date specified in the decision and, where a later date is so specified, the decision comes into operation on that date.
…
41 The AAT Act thus draws a clear distinction between the decision of the Tribunal under s 43 which is, relevantly, what causes the 84 day period to stop running, and the reasons for decision. In BTR plc v Westinghouse Brake and Signal Company (Australia) Ltd (1992) 34 FCR 246 the Tribunal had handed down a decision on a review of a decision of the Australian Securities Commission that was before it, confirming an exemption that the Commission had granted on certain conditions, but substituting different conditions. At the time of announcing the decision the Tribunal did not give any reasons. It delivered written reasons some 14 days later. Beaumont J held (at 271-273, Lockhart and Hill JJ agreeing at 253) that the Tribunal's omission to provide reasons at the time of announcing its decision was not an error, as on the proper construction of s 43(2) of the AAT Act, the Tribunal was only required it to give its reasons, oral or in writing, within a reasonable time of the decision.
42 In his written submissions filed after the appeal hearing in this case, the Minister conceded that the decision in BTR reflects the correct interpretation of s 43(2) of the AAT Act 'as referred to in s 500(6C) [sic 500(6L)] of the Migration Act'. It may be that what is a reasonable time for delivering reasons in the present context is influenced by the 35 day time limit for applications for judicial review of the Tribunal's decision that is found in s 477A(1) of the Migration Act. But it is not necessary to determine that for present purposes; it is clear that the Tribunal misdirected itself as to the law when it proceeded on the basis that it had to both deliver a decision and produce written reasons by 26 February 2018.
43 The jurisdiction of the Federal Court to review decisions of the Tribunal in the present context is limited to jurisdictional error: Migration Act s 476A(2). Not every error of law is a jurisdictional error: see the recent analysis in Tsvetnenko v United States of America [2019] FCAFC 74; (2019) 367 ALR 465 at [33]-[40]. In a statutory decision making process, jurisdictional error is a failure to comply with one or more statutory preconditions or conditions to an extent which results in a decision which has been made in fact lacking characteristics necessary for it to be given force and effect by the statute pursuant to which the decision maker purported to make it: Hossain v Minister for Immigration and Border Protection [2018] HCA 34; (2018) 359 ALR 1 at [24] (Kiefel CJ, Gageler and Keane JJ). 'The question is always one of construction of the legislation: which breaches of a provision does the legislation, either expressly or, more commonly, impliedly, treat as depriving the decision maker of power?': Hossain at [67] (Edelman J, Nettle J agreeing).
44 Here, the immediate source of the power that the Tribunal exercised in adjourning the hearing on 19 February 2018 was s 40(1)(c) of the AAT Act, which provides that for the purpose of reviewing a decision, the Tribunal may adjourn the proceeding from time to time. However it is not the decision made in exercise of that power which Mr Khalil challenged, it was the decision that it made on 26 February 2019 under s 43(1)(a) to affirm the delegate's decision. That paragraph of the legislation provides, in effect, that for the purpose of reviewing a decision, the Tribunal may exercise all the powers and discretions that are conferred by any relevant enactment on the person who made the decision and shall make a decision in writing either to affirm, vary or set aside the decision under review.
45 As Edelman J indicated in Hossain, the AAT Act does not explicitly set the jurisdictional boundaries of either the power to adjourn or the power of review. Section 33 stipulates that in a proceeding before the Tribunal, its procedure is within its discretion, but that is expressly made subject to the Act and the regulations and to any other enactment. The same provision also requires that the proceeding is to be conducted with as little formality and technicality, and with as much expedition, as the requirements of the Act and of every other relevant enactment and a proper consideration of the matters before the Tribunal permit. Even allowing for informality and a relative lack of technicality, that cannot be construed as indicating that the Tribunal is free to err at large in relation to the procedures that it follows on review.
46 It is also to be observed that the numerous provisions of the Act that govern the procedures of the tribunal are quite prescriptive. We have already referred to the requirement in s 39 that the Tribunal give every party to a proceeding a reasonable opportunity to present his or her case. Other examples include: an express power granted to allow a person to participate in hearings by telephone or by means of other communications equipment (s 33A(1)); express limitations on when the Tribunal may dispense with a hearing (s 34J); the lengthy and detailed provisions setting out the various ways in which the Tribunal may complete a review (s 42A-s 43(1)); and the detailed provisions governing publication of decisions and the provision of reasons (s 43(2)-s 43(5)).
47 These provisions, in our view, indicate that the legislation does not empower the Tribunal to proceed on the basis of a misconception of the nature of its task as fundamental as that which infected the Tribunal's conduct of the hearing and, through that, its ultimate decision in this case. While past decisions, even those of the High Court, are not to be treated as laying down rigid categories or definitions of jurisdictional error, we are fortified in our conclusion by the fact that the error is of a kind represented by (at least) one of the examples given in Craig v State of South Australia (1995) 184 CLR 163 at 177-178, namely misconstruing the statute and thereby misconceiving the nature of the function which it is performing.
48 What the Tribunal had to do here within the 84 days was to deliver a decision, not necessarily express reasons. It might be argued that the error was only one as to the timing of delivery of reasons, not the nature of the task. But in our view, on the proper construction of the AAT Act, and in the context of the serious constraints imposed on the review by the combination of that 84 day limitation and Mr Rodgers' abandonment of Mr Khalil on the morning of the hearing, that was an error of such gravity (see Hossain at [25]) that it should be characterised as jurisdictional. No contrary intent appears in the AAT Act (or the Migration Act), and in the absence of such intent 'an administrative tribunal lacks authority either to authoritatively determine questions of law or to make an order or decision otherwise than in accordance with the law': Craig at 179.
49 However, the Act is not to be interpreted to deny legal force to the decision unless the resulting breach of the limitations on the Tribunal's powers was material to the decision: Hossain at [29]-[31]; Minister for Immigration and Border Protection v SZMTA [2019] HCA 3; (2019) 363 ALR 599 at [44] (Bell, Gageler and Keane JJ, but see Nettle and Gordon JJ dissenting on this point). A breach is material to a decision only if compliance could realistically have resulted in a different decision. That is an ordinary question of fact on which the applicant for review bears the onus of proof, and which may be determined from inferences drawn from the evidence: SZMTA at [45]-[46].
50 In ascertaining the materiality of the error here, it is necessary once more to keep in mind the distinction between the decision to adjourn and the decision that is challenged, namely the outcome of the review. It is clear from the excerpts from the hearing of the Tribunal quoted above that the Tribunal's error was material to the former decision. Was it also material to the latter? That is, could the decision made under s 43 of the AAT Act have been different if the Tribunal had appreciated that it did not need to deliver written reasons for the decision until a reasonable time after Monday, 26 February 2018?
51 In our view, it could have been. Certainly, the Tribunal had a duty to deliver a considered decision on 26 February 2018. If the Deputy President had appreciated the true distinction between his obligation to make a decision and his obligation to give reasons, he could not have been fairly criticised if he had declined to hold the hearing on that day, so as to reserve sufficient time for consideration over the weekend. But it can be concluded on the basis of the common experience of courts and tribunals that writing out reasons in publishable form takes much longer than the mental process of identifying the correct decision and what the reasons for it will be. In fact, on 26 February 2018 the Tribunal delivered detailed written reasons some 25 pages long. In our view it can be inferred from the concerns that the Deputy President did express about the time it was going to take to produce his reasons that if he had been able to write reasons after 26 February, he would have adjourned the hearing at least until Thursday 22 February, and quite possibly to Friday 23 February.
52 It is true that, even then, Mr Khalil could not have presented any additional information orally at the hearing unless he had set it out in a written statement given to the Minister at least two business days before the hearing (Migration Act s 500(6H)), and that he could not have relied on any further document in support of his case unless he gave a copy to the Minister at least two business days before the hearing (s 500(6H)). But those restrictions did not prevent him from making (at least) oral submissions based on the material that was before the Tribunal or, perhaps more to the point in the circumstances, having oral submissions made on his behalf: Jagroop v Minister for Immigration and Border Protection [2014] FCAFC 123; (2014) 225 FCR 482 at [102]-[103]. While he would undoubtedly have faced difficulties in procuring an alternative legal representative as quickly as he needed to, and had been unable to do so within the 24 hours allocated to him, the possibility of securing such representation with a little extra time was not an unrealistic one. Any such representative would have to master a volume of material running to some 370 pages which, while not an insubstantial task, was eminently achievable for a hearing of this nature.
53 In our view the possibility that the outcome would have been different if Mr Khalil had secured that representation was a real one. His offending, while serious and undoubtedly of an extent which meant he did not pass the character test, was not at the extreme end of the scale. There was material in the G documents which could have formed the basis for submissions about matters such as the interests of his minor children and his wife, and counselling and rehabilitation programs he had completed. Yet in the circumstances, the hearing on 20 February 2018 consisted of little more than cross-examination by the solicitor acting for the Minister and a brief statement by Mr Khalil at the end of the hearing, consisting of emotively expressed generalities. Consistently with this, the Tribunal's reasons placed a great deal of emphasis on the seriousness of the offending and little emphasis on the interests of the children and other factors we have mentioned.
54 This is not to say that the Tribunal's decision on the merits was incorrect - that is not the question for present purposes. It is enough to say that a moderately skilled advocate would have been able to make significantly more of the material that Mr Khalil did in the circumstances. Minister for Immigration and Border Protection v WZARH [2015] HCA 40; (2015) 256 CLR 326 is an example of a case where the manner in which a hearing is conducted on behalf of an applicant can affect relatively intangible factors such as the impressions formed by a decision maker and the coverage, detail and emphasis of submissions, in such a way as to potentially make a difference to the outcome of a hearing, so as to merit judicial review: see especially the discussion at [38]-[44] (Kiefel, Bell and Keane JJ) and [66] (Gageler and Gordon JJ).
55 In all the circumstances, we consider that if the Tribunal had not misdirected itself on the subject of when it was required to produce reasons for its decision, the outcome for Mr Khalil could, realistically, have been different. Jurisdictional error is established and grounds 1 and 2 should be upheld.
