Ground One
26 The appellant described the issues arising in relation to the first ground in the following terms:
Having excluded the applicant from his own review, two questions arise:
(1) Did the Act authorise the Tribunal to exclude the applicant from the hearing of his own review application?
(2) If so, did the Tribunal exercise that power reasonably?
27 The parties agreed that the Tribunal's obligation in s 429 of the Migration Act to hold a review hearing in private does not preclude the Tribunal conducting a joint hearing, if it does so in order to pursue the objectives set out in s 420 and does so in a way which affords procedural fairness to the applicants concerned: SZAYW v Minister for Immigration and Multicultural and Indigenous Affairs [2006] HCA 49; 230 CLR 486 at [27]. The appellant's complaint is not the Tribunal's decision to hold a joint hearing, but its decision to exclude G from his own review hearing while it took evidence from his brother W, as a witness in G's review.
28 As is clear from the way the appellant framed the issues, the appellant challenged the exclusion as both a matter of power, and of discretion.
29 As to the power argument, there was no debate between the parties there was no express power of exclusion, unlike s 35 of the Administrative Appeals Tribunal Act 1975 (Cth). The Minister contended this difference was explicable because generally Administrative Appeals Tribunal hearings are required to be conducted in public (s 35(1) of the Administrative Appeals Tribunal Act) and thus an express power of that nature is required. The appellant contended that the absence of such an express power tells against any implication.
30 The appellant correctly contends that s 425 of the Migration Act, read with s 414, confers on an applicant for review a substantive right to a hearing before the Tribunal as an important and central right in the merits review system established by Pt 7 of the Act: Liu v Minister for Immigration and Multicultural Affairs [2001] FCA 1362; 113 FCR 541 at [44], [47] (Black CJ, Hill and Weinberg JJ).
31 Although the review hearing is required to be held "in private" pursuant to s 429, the appellant is also correct to contend that the benefit of the privacy required by s 429 is for the benefit of an applicant, and this requirement is not one which the scheme intends can be used as a basis for excluding him, or justifying his exclusion because principles of open justice do not apply. The privacy requirement has a protective function. Like other provisions in the Migration Act (such as s 431), it is designed to ensure that an applicant's identity and the details of his or her claims (and those she or he may identify as part of articulating her or his claims) are not publicly available in order that the protections which the 1951 Refugees Convention enshrines for those seeking asylum and for those found to be refugees are not frustrated by the domestic assessment process undertaken pursuant to the Act.
32 The Explanatory Memorandum to the Migration Reform Bill 1992 (Cth) described the need for such a provision (at [377]) in the following terms:
This section provides that the review must be in private. This protects applicants and their families as there is a risk that if refugee claims are dealt with in public they may give rise to difficulties for dependents remaining in the country of origin. At the outset of processing, persons seeking protection on refugee status grounds are assured that all details of their applications will be kept strictly confidential. In particular they are assured that information will under no circumstances be passed to authorities in their own country. This is essential to ensure that applicants are willing to canvass their reasons for seeking protection in an open and frank manner. This section is intended to allow the same guarantee of confidentiality at the review stage.
33 As we set out below, the authorities which have examined s 429 construe it in this light.
34 The appellant submits no power to exclude an applicant from a hearing should be implied, referring in this context to circumstances where courts have refused to imply such a power (see for example Selfe v Isaacson (1859) 1 F & F 194; 175 ER 688; London Chartered Bank v Lavers (1855) 2 Legge 884). Both these cases do concern circumstances in which the Court recognised a right in a party to remain in court during a proceeding to which he was a party. In Lavers, the report notes the "recent amendment of the law permitting parties to a suit to give evidence for themselves". The Court held that, despite a party now also being capable of being a witness (and therefore, it implied, subject to the ordinary processes of exclusion while other witnesses were giving evidence), that party retained a right "to remain in Court for the conduct of his case".
35 The Minister submits there are no parallels with such authorities, one reason being there are no "parties" before the Tribunal and the proceeding is not adversarial. Whether these attributes of a court proceeding where judicial power is exercised wholly explain the approach taken by the Courts may be debatable. It may also be that the continued recognition of a party's right always to remain in court during the conduct of her or his proceeding, even if she or he will be a witness (and often a key witness) also reflects fundamental notions of procedural fairness, a rationale not confined to exercises of judicial power. Where a person is subject to any exercise of public power that involves a hearing process, it is a large implication that the jurisdiction can be exercised in the absence of such a person. In the United Kingdom the Supreme Court has held that where there are no statutory modifications there is no inherent power in a court, whether in a civil or criminal trial, to allow one party and the court to rely on material which is kept from another party and its legal representatives: see Al Rawi v Security Service [2011] UKSC 34; [2012] 1 AC 531; R (British Sky Broadcasting Ltd) v Central Criminal Court [2014] UKSC 17; [2014] AC 885; R (B) v Westminster Magistrates' Court [2014] UKSC 59; [2015] AC 1195. In Assistant Commissioner Condon v Pompano Pty Ltd [2013] HCA 7; 252 CLR 38 at [170], the plurality declined to determine the validity of such a proposition in the Australian context. Pompano itself is an example of valid state legislation involving non-disclosure of material to a party and that party's legal representatives in the context of a proceeding. There are other examples of exercises of similarly exclusionary legislative power being found valid: see K-Generation Pty Ltd v Liquor Licensing Court [2009] HCA 4; 237 CLR 501 at [143]-[149] and Gypsy Jokers Motorcycle Club Inc v Commissioner of Police (WA) [2008] HCA 4; 234 CLR 532 at [7], [30]-[36], [44], [175]-[189].
36 Whether the implication of any such power is necessary or appropriate to the exercise of the Tribunal's review jurisdiction may be susceptible to different answers. The Act itself contains express measures designed to limit the access of applicants to information held by the Tribunal and on which it might act (see for example s 424A(3)(c) and the definition of "non-disclosable information" under s 5 of the Act). Outside the application of express provisions of that nature, the Tribunal must disclose at least the substance of information received by it which may be credible, relevant and significant to the review: see Applicant VEAL of 2002 v Minister for Immigration and Multicultural and Indigenous Affairs [2005] HCA 72; 225 CLR 88 at [15]-[17].
37 Against those considerations is the well recognised flexibility of merits review processes such as those in which the Tribunal is engaged under Pt 7 of the Act. That flexibility was evident in the process adopted by the Tribunal in SZAYW [2006] HCA 49; 230 CLR 486 where the Tribunal held four review hearings together. At [9]-[15] the joint reasons of the Court described the circumstances before the Tribunal in those reviews:
The appellant, and three of his friends who were described as applicants 226, 228 and 229, were stateless Palestinians who had been living in Lebanon. They all left Lebanon and travelled to Australia. They all claimed to fear that, if they returned to Lebanon, they would be persecuted by Hezbollah or Islamic Jihad. The basis of that fear was said to be that together they had become involved with Hezbollah, and had received military training for the purpose of attacking Israel or Israeli interests in South Lebanon. They had lost their enthusiasm for the conflict, and left Lebanon. They feared that, if they returned, they would suffer reprisals for desertion. The Tribunal rejected their claims that they had a well-founded fear of persecution. The Tribunal's reasons for that conclusion are not presently material. A substantial part of their evidence was disbelieved.
After the four original applications for protection visas were refused by a delegate of the first respondent, Refugee Advice and Casework Service (Australia) Inc ("RACS") wrote to the Tribunal on behalf of each man. The letter concerning the appellant said:
"We confirm that we act for [the appellant] in his application for review of the decision refusing to grant a Protection Visa.
Please find attached an application for review signed by him.
We note that the four young men ... were together for the events which form their claim. We ask therefore that consideration be given to the same member being allocated to the four persons."
(Emphasis added.)
The reference, in the singular, to the claim of the four men was consistent with the manner in which the matter was presented to the Tribunal. At no stage was there any suggestion that their interests, or their cases, conflicted. Evidently, RACS felt no embarrassment in representing them all. As the Tribunal member recorded in her reasons relating to the appellant's application for review, "the group's claims were based on experiences all four claimed to have shared in common". In argument to the Tribunal, RACS relied upon the consistency of the claims made by the four men and submitted that "their claims are furthermore strengthened by each other's testimony". The four applicants for review were making common cause, and argued that their individual claims should be regarded as more credible because of the consistency of their accounts of their shared experiences in Lebanon.
The Tribunal agreed to the request that the one member be assigned to deal with all four applications for review. The same date (7 April 1999) was fixed as the date for all four hearings. One applicant was a little late in arriving. All four were represented by RACS. The girlfriend of one of the applicants (not the appellant) was present. All applicants had previously received written notices, in standard form, from the Tribunal, inviting them to state whether they wanted to bring someone to the hearing, and indicating that such a person could be an adviser, friend or relative.
The appellant and the other two applicants who were present at the beginning were sworn in each other's presence. The latecomer was sworn when he arrived. The Tribunal member said that she would explain the Refugees Convention to all applicants collectively, and that she would then talk to them all individually. She said that the girlfriend of one of the applicants could be present for moral support while he gave evidence, but not while the appellant and the other applicants were being questioned. At that stage the Tribunal member intended to question the applicants separately. She offered the migration advisers the opportunity of being present during all four hearings, and the offer was accepted.
The Tribunal member took evidence from one of the applicants (not the appellant) in the absence of the others. This lasted about three hours. The member then decided to question the appellant and the other two applicants together. In her reasons she later explained that, by the end of the questioning of the first applicant, it had become apparent that the claims were all based on shared experiences. At the time, she said to the applicants:
"[A]lthough your stories are very similar ... and I can think of you as a group in a certain way in listening to what you have to say at the same time I have to consider you as individuals and I don't want to lose sight of that fact."
The Tribunal member then questioned the three remaining applicants (including the appellant) together, in the presence of their migration advisers. This took about two hours. Two interpreters were used. No complaints or objections were raised about the procedure, either then or at any time before the Tribunal's decisions were made. After 7 April 1999, RACS made lengthy written submissions to the Tribunal concerning the claims of the appellant and the other applicants.
38 The argument in SZAYW was in some respects the converse of the argument in the present appeal: it was that the appellant was entitled, by reason of s 429, to a hearing "in private" without other review applicants present. The High Court did not agree, emphasising the protective function of s 429 was not necessarily infringed by the presence of other people with whom the appellant shared a common cause or interest. As to the Tribunal's procedural choices at a more general level the Court said (at [27]):
Section 429 does not necessarily prevent hearings which are wholly or partly concurrent, if that course is dictated by the objectives stated in s 420 and is consistent with procedural fairness. It is not difficult to think of cases, such as those involving separate applications by members of the one family, where that could be appropriate. In some circumstances s 429 may present an obstacle to that course; but not in the circumstances of this case.
(Emphasis added.)
39 The Minister's submission on this appeal about SZAYW was, in effect, that if there was no power in the Tribunal to conduct a proceeding by way of joint hearings and the exclusion of applicants at various times or stages of the review hearing, then that issue was so likely to have been raised in SZAYW that this Court could comfortably be satisfied that the High Court saw no difficulties in terms of the Tribunal's power to conduct the review as it did. In our opinion, the qualifications given by the Court, which we have emphasised, are contrary to the Minister's somewhat speculative submission.
40 The other case on which the Minister relied in this context was SAAP v Minister for Immigration and Multicultural and Indigenous Affairs [2005] HCA 24; 228 CLR 294. In our opinion, there is more force in the Minister's reliance on dicta in that case, but no greater force in the submissions that the High Court "would have" made observations about power if no such power should be implied. Rather, the relevant point which we draw from SAAP concerns the nature of the review conducted by the Tribunal.
41 Gleeson CJ at [10] set out the way in which the challenge to the conduct of the review by the Tribunal in SAAP arose:
The essential facts may be stated briefly. The first appellant, who at different times was represented by a solicitor and a migration adviser, applied to the Tribunal for review of an unfavourable decision by a delegate. She was in immigration detention. A hearing of her application took place on 5 September 2001. The proceedings were conducted by video-link between Sydney and Woomera Hospital. The Tribunal Member was in Sydney, together with the first appellant's migration adviser, an interpreter, one of the first appellant's daughters, and other witnesses. The first appellant was at Woomera. Since the issue in the case is procedural, it is unnecessary to go into the substance of the first appellant's claims for refugee status. At one point in the proceedings, the Tribunal Member took evidence in Sydney from the first appellant's daughter. After the daughter's evidence was given, the Tribunal Member raised with the first appellant, for her comment, three particular matters about which the daughter had given evidence. For reasons that need not be examined, those matters were potentially adverse to the first appellant's case. The first appellant made her response to each matter. The first appellant's migration adviser heard the daughter's evidence, the Tribunal Member's questions to the first appellant, and the first appellant's responses. The Tribunal Member then brought the hearing to a close, leaving it open to the first appellant or her migration adviser to make further oral or written submissions. No further submissions were made, but the migration adviser wrote to the Tribunal asking for a prompt decision because of the state of the first appellant's health. A decision was then given. It was unfavourable to the first appellant.
42 The legal issue in SAAP (being one to which the enactment of s 424AA was a legislative reaction) concerned the scope of s 424A, and whether compliance by the Tribunal with its terms could be achieved by the Tribunal member informing an applicant orally at the hearing of the issues with which the provision dealt. At [8], Gleeson CJ explained the wider context of the procedural fairness obligation contained in s 424A in terms which are apposite to the issue raised by ground one on this appeal:
What is described in s 429 as the hearing is to be understood in the wider statutory context. The prescribed procedure is not that of adversarial litigation, with evidence taken and issues debated at a climactic trial. Indeed, in many cases there will not be a hearing. The procedure is administrative and inquisitorial. Even so, the statutory references to appearance and hearing, adjournment, summoning witnesses, taking evidence, and proceeding to decision in default of appearance, show that this is a form of administrative decision-making which, having the capacity to affect human rights, borrows from judicial procedure. While it is true that fairness in administrative decision-making is not measured by reference to a judicial paradigm, judicial procedure ought to be an example of fairness in action, and it is not surprising to find some aspects of that procedure taken up for some administrative purposes.
43 The point made in the first few sentences is, in our respectful opinion, the critical one for the resolution of the present appeal. Unlike an adversarial trial, where the decision-making entirely depends on evidence adduced during the trial itself, and the testing of that evidence also during the trial, an administrative merits review of the kind established by Pt 7 of the Act occurs on a continuum from the lodging of an application through to a decision. A hearing pursuant to s 425 may be a necessary part of that process but it is neither the beginning nor the end of the making of the correct or preferable decision. Subject always to its express or implied obligations of procedural fairness (which, as McHugh J observed in SAAP at [60] is a continuing obligation throughout the review process), a Tribunal member as merits decision-maker may examine and consider material outside any review hearing, and may be proactive in obtaining extra material for herself or himself, including after a s 425 review hearing (see SAAP at [125] per Gummow J).
44 We note for example the powers in s 424 (to seek information, whether orally or in writing), s 427(1)(d) (to require the Secretary to make arrangements for any "investigation" or medical examination the Tribunal thinks necessary with respect to the review) and s 428 (the Tribunal may authorise another person to take evidence for the purpose of a review, whether inside or outside Australia), all of which contemplate that evidence and other material relevant to a review will be obtained in the absence of an applicant. Again, we note all these powers may be subject to the Tribunal's express and implied obligations of procedural fairness. Notwithstanding provisions such as s 422B, there remains scope for the operation of common law procedural fairness principles in the Tribunal's review pursuant to Pt 7: see Saeed v Minister for Immigration and Citizenship [2010] HCA 23; 241 CLR 252 at [35]-[42].
45 The observation by Gleeson CJ in SAAP at [21] that the object of a review hearing pursuant to s 425 is to "hear evidence and receive arguments in the most useful and efficient manner" which will often "involve flexibility in the order of proceedings" is also apposite.
46 The decision-making process for which Pt 7 of the Act provides demonstrates, in our opinion, that evidence and information may be obtained by the Tribunal in the absence of an applicant at various points, and more than once. The process expressly contemplates this will occur and it is the express and implied requirements of procedural fairness which operate to ensure that an applicant is given a reasonable opportunity to deal with, and address, any information and evidence so obtained, subject to any express requirements in the Act that this not occur (such as s 424A(3)(c), to which we have referred above).
47 Accordingly, and although it is significant to construe s 425 itself (or ss 414 and 415) as authorising the taking of evidence at a review hearing in circumstances where a review applicant has been excluded from part of the hearing, we consider that construction to be the preferable one, subject, as we have emphasised, to the Tribunal's express and implied obligations of procedural fairness.
48 In those circumstances, the Tribunal has a discretionary power to require a review applicant to leave a s 425 hearing so that the Tribunal may take evidence in the absence of the review applicant. That discretion must not be exercised in a way which is legally unreasonable (see Minister for Immigration and Citizenship v Li [2013] HCA 18; 249 CLR 332 at [27]-[28], [72] and [105]). Where no reasons are given by the decision-maker for the manner in which a discretion was exercised, then the task of a reviewing court is to examine the outcome of the exercise of discretion and to consider, for itself, whether the discretion was exercised in a way which is justifiable and intelligible, bearing in mind it is for the repository of the discretionary power to exercise it, not the court: see Minister for Immigration and Border Protection v Singh [2014] FCAFC 1; 308 ALR 280 at [45].
49 The Tribunal's reasons for decision do not explain why it took the course it did on 25 February 2013. There were some remarks to which the Court was taken in the transcript of the review hearing, and which we have extracted at [12] above. Further, in its letter to the brothers through their migration agent on 10 January 2013, the Tribunal stated (as we have extracted at [9] above) that it proposed to take this course "to avoid your evidence being affected by the evidence of the other". As the appellant submitted, in fact the Tribunal excluded G after he had given his evidence and while it took his brother's evidence. We do not consider that fact nullifies the Tribunal's justification, such as it is, or renders it unintelligible. The Tribunal was not to know whether it might need to ask G further questions after having heard W's evidence. It was not to know what effect having G, as the older brother, in the hearing room while W, as the younger brother, gave evidence might have on what W had to say. These matters were within the concept of the "effects" the Tribunal might have apprehended could flow from the brothers being present during each other's evidence. In a review where the reliability and credibility of the factual accounts given by each brother was critical, and on the basis that s 425, alternatively ss 414 and 415 (or all of them) authorised the Tribunal to exclude each of the brothers, we do not consider its exercise of discretion lacked justification, or was unintelligible so as to render its exercise legally unreasonable.
50 For those reasons, ground one is not made out, but the qualifications we have emphasised about procedural fairness arise in respect of the next two grounds.
