CONSIDERATION
41 The Tribunal's decision was a "privative clause decision" within the meaning of s 474 of the Act. As a result, it can only be set aside on judicial review if jurisdictional error is shown: see Plaintiff S157/2002 v Commonwealth of Australia (2003) 211 CLR 476 at 506-508 and 511.
42 The Federal Magistrate based his decision principally on s 360 of the Act. This provision requires the Tribunal to "invite the applicant to appear before the Tribunal to give evidence and present argument relating to the issues arising in relation to the decision under review". The Act, in s 425, imposes an equivalent obligation on the Refugee Review Tribunal. The Tribunal is bound to extend an invitation under s 360 where the documentary material before it would not lead it to make a decision in the review applicant's favour: see ss 360(2) and 425(2).
43 The Minister accepted that an invitation under s 360 of the Act must be a genuine invitation to attend a hearing that affords a real opportunity to present evidence and arguments on the issues raised in relation to the decision under the review: see Minister for Immigration and Multicultural and Indigenous Affairs v SCAR (2003) 128 FCR 552 at 560-561 per Gray, Cooper and Selway JJ; Minister for Immigration and Multicultural Affairs v SZFDE (2006) 154 FCR 356 at 388-389 per French J and 400 per Allsop J; and SZBEL v Minister for Immigration and Multicultural and Indigenous Affairs (2006) 231 ALR 592 at 600. The Minister conceded that the obligation to which s 360 gave rise was a continuing one.
44 Nonetheless, I accept the Minister's submission that there was, in this case, no breach of s 360(1). Pursuant to s 360(1), by a letter dated 15 February 2006, the Tribunal invited Ms Le to a hearing on 7 March 2006. As we have seen, Ms Le and Mr Nguyen attended this hearing with a number of witnesses. The Tribunal subsequently wrote to Ms Le's representative in accordance with s 359A(1) of the Act and her representatives replied on her behalf.
45 The transcript shows that the Tribunal member foreshadowed the possibility of a further hearing as soon as it appeared to her that not all the witnesses would be reached in the available time. The Tribunal raised this possibility first in the presence of Ms Le and later in the presence of Mr Nguyen. The interpreter was assisting Ms Le and Mr Nguyen at these times. As we have seen, however, the critical exchange occurred at the conclusion of Mr Nguyen's evidence and after the interpreter's departure. Mr Nguyen was the last witness to give evidence that day.
46 Did it matter that this exchange took place only between the Tribunal and Mr Oladejo and in the absence of Ms Le and an interpreter? For the following reasons, I do not think so. I accept that, as the Minister submitted, this was not a case in which the Tribunal did not complete the steps in the review process that it considered necessary to afford a real, in the sense of fair, opportunity to present evidence and arguments: compare Sok v Minister for Immigration and Citizenship [2007] FCA 413 at [52] per Kenny J.
47 It is immaterial that Mr Oladejo had no right to address the Tribunal, providing he had the capacity to answer the Tribunal's enquiries of him on Ms Le's behalf. Although present to assist Ms Le, Mr Oladejo had no right to address the Tribunal at the hearing on 7 March 2006. The right (though not the capacity) of someone other than the review applicant to address the Tribunal at a hearing is circumscribed by the Act. When appearing before the Tribunal, the review applicant is entitled to have another person present to assist, although the assistant is not entitled to present arguments or address the Tribunal, unless the Tribunal is satisfied that exceptional circumstances justify the assistant in doing so: see s 366A(1) and (2). The review applicant has no other right to representation when appearing before the Tribunal: see s 366A(3). The Act does not, however, limit the capacity of another person to assist the review applicant at a hearing, when he or she is invited by the Tribunal to do so. Whether a person has the capacity to assist will generally depend on the relationship between the review applicant and the other person.
48 It is clear enough that Mr Oladejo had the capacity to discuss the further conduct of the hearing with the Tribunal on Ms Le's behalf. Section 366A of the Act does not affect a review applicant's right to engage a representative otherwise than while appearing before the Tribunal: see s 366A(4). In the present case, Ms Le had instructed the law firm of Koenig and Simons to act for her in relation to her review application. Mr Oladejo was apparently a consultant to the firm. Furthermore, as we have seen, on the day of the hearing, Ms Le specifically advised the Tribunal that she had appointed Mr Oladejo as her representative to act on her behalf in relation to her application and to be an "authorised recipient". The Act plainly contemplates that review applicants can appoint representatives to act on their behalf in relation to proceedings before the Tribunal: see, e.g. ss 276, 277, 312B, 332G and 368C. Generally speaking, these representatives will be registered migration agents, although there are other specified persons who may also assist. Under s 312B of the Act, a registered migration agent must notify the Tribunal when he or she gives immigration assistance to a person in relation to a review application after agreeing to represent the review applicant in respect of the review. Furthermore, the transcript shows that, from the outset of the hearing and with Ms Le's tacit consent, the Tribunal permitted Mr Oladejo to act as her representative and he did so act. Amongst other things, before the critical exchange, the Tribunal had already exchanged comments with him concerning the possibility of a further hearing. The interpreter was, of course, present on these earlier occasions and, on the first two occasions, so too was Ms Le.
49 Further, in keeping with his appointment as her representative, Ms Le also nominated Mr Oladejo as her "authorised recipient" for the purposes of the Act. The appointment of an authorised recipient attracts the provisions of s 379G of the Act. Under s 379G(1), a review applicant may give the Tribunal written notice of another person who is authorised "to do things on behalf of the applicant that consist of, or include, receiving documents in connection with the review" and, in this event, the Tribunal must give the authorised recipient, instead of the applicant, any document that it would otherwise have given to the applicant, although s 379G does not apply "to the Tribunal giving documents to, or communicating with, the applicant when the applicant is appearing before the Tribunal": see 379G(5).
50 The circumstances may show, as they do in this case, that the review applicant has authorized another to represent him or her, as the law permits, for the purposes of communications between him or her and the Tribunal. Although the Act makes specific provision for the manner of certain written communications, it does not do so in respect of oral communications with a review applicant's representative of the kind in question in this case.
51 The communication between the Tribunal and Ms Le's representative was not rendered nugatory because it was not contemporaneously translated to Ms Le. There is no basis in the Act or elsewhere to require that any oral communication between the Tribunal and the review applicant's authorised representative be translated contemporaneously to the review applicant. The Tribunal has no general duty to provide an interpreter on every occasion when it is seeking to communicate with a review applicant. The Act does impose an obligation to provide an interpreter where a request is made by a person appearing before the Tribunal to give evidence for the purposes of communication between the Tribunal and that person, unless the Tribunal considers the person sufficiently proficient in English: s 366C(1) and (2). Moreover, the Tribunal must provide an interpreter if the Tribunal considers that a person appearing before it to give evidence is not sufficiently proficient in English, even though no request was made: s 366C(3). Obviously, this obligation extends to a review applicant where he or she is appearing to give evidence and lacks proficiency in English. In this case, the Tribunal had complied with its obligations under s 366C by providing an interpreter, as requested, for the review applicant and other witnesses when they gave their evidence to the Tribunal. It was not, however, obliged to ensure that its discussion with Ms Le's representative regarding the possibility of a further hearing was translated to Ms Le herself.
52 It does not follow from this that a representative is at large with respect to his client's affairs. Registered migration agents (as Mr Oladejo was required to be) are subject to regulation by the law, including the Act, the Migration Agents Regulations 1998 (Cth), and the Code of Conduct made under these Regulations and s 314(1) of the Act. Under the Code, registered migration agents are required to act in the lawful interests of their client at all times (clause 1.12); to deal with their clients competently, diligently and fairly (clause 2.1); and to have due regard to a client's dependence on the agent's knowledge and experience (clause 2.4). Further, they "must … within a reasonable time after agreeing to represent a client, confirm the client's instructions in writing to the client; … act in accordance with the client's instructions; and … keep the client fully informed in writing of the progress of each case or application that the agent undertakes for the client…": clause 2.8. Mr Oladejo was thus obliged to seek Ms Le's instructions on the matter of a further hearing and, for this purpose, to inform her of his discussion with the Tribunal.
53 For these reasons, I accept the Minister's contention that there was no proper basis for the Federal Magistrate to conclude that the Tribunal's repeated offers to conduct a hearing were not genuine merely because the offers were made to Mr Oladejo and were not contemporaneously translated to Ms Le. Accordingly, I accept the Minister's submissions with respect to the first ground of appeal advanced at the hearing of the appeal.
54 Further, having regard to the transcript and the Tribunal's reasons for decision, there was no warrant for the Federal Magistrate's finding, if this is what it was, that the Tribunal sought to transfer its responsibilities regarding a further hearing to Ms Le's representative. In this context, it must be borne in mind that the Tribunal is bound to consider the review applicant's wishes, although it does not have to act on them. Section 361(3) of the Act provides in effect that the Tribunal must have regard to the review applicant's wishes, as expressed in a notice under s 361(2), as to the witnesses that should be called to give oral evidence. In the exchanges about the possibility of a further hearing, the Tribunal was in substance asking whether the review applicant's wishes, as expressed at the outset of the hearing, remained the same and thus whether she wished to have the hearing continued on another day when an interpreter was available. Although not obliged to comply with Ms Le's wishes, it was open to the Tribunal to take the view that Ms Le, as advised by Mr Oladejo, was in the best position to assess whether, in view of what had occurred at the 7 March hearing, the s 359A letter and her response to it, the remaining witnesses should be asked to give their evidence at a further hearing. Since Ms Le did not request a further hearing after the s 359A letter, then, it was open to the Tribunal to conclude that, having regard to the evidence and other material already before it, including the discussion with Mr Oladejo, there was no call for a further hearing. The Minister's fifth ground of appeal is thus made out.
55 As we have seen, the Minister submitted that the Federal Magistrate did not have proper regard to the burden of proof. Issues regarding the burden of proof are not always straightforward in judicial review proceedings. To quote Sir William Wade and Christopher Forsyth in Administrative Law (9th ed, 2004, Oxford University Press) at 292:
"Where the validity of an administrative act or order is attacked, the incidence of the burden of proof may vary with the circumstances. The burden of proof naturally lies in the first instance upon the plaintiff or complainant. Whether he can transfer it to the defendant public authority depends upon the nature of the act."
56 I accept that, as the Minister contended, it was incumbent on Ms Le, as an applicant for judicial review, to present some evidence that Mr Oladejo had not communicated to her that the Tribunal was prepared to convene a further hearing if the failure so to communicate was part of her case: compare Rose v Bridges (1997) 79 FCR 378 at 386 per Finn J. There was, as the Minister said, no evidence before the Federal Magistrate that Mr Oladejo had failed to inform Ms Le, through an interpreter, that the Tribunal was willing to reconvene to hear the evidence from the remaining witnesses. Ms Le did not seek to adduce any evidence to this effect. Accordingly, it was not open to his Honour to proceed (as he apparently did) on the basis that Mr Oladejo had not conveyed this information to Ms Le, in breach of his obligations to her. To the extent that his Honour did so proceed, he was in error. I would accept the Minister's submissions under the second ground of appeal.
57 Part of the Minister's challenge to the judgment under appeal involves a challenge to findings, if this is what they were, that were in the nature of findings of fact or mixed fact and law. This Court must make its own assessment in light of the judgment under appeal. In a case of this kind, the appellate court is in as good a position as the Federal Magistrate to form a view about any facts in issue: compare Warren v Coombes(1979) 142 CLR 531 at 551-552 per Gibbs ACJ, Jacobs and Murphy JJ andFox v Percy (2003)214 CLR 118 at 127 per Gleeson CJ, Gummow and Kirby JJ.
58 As noted, the Minister challenged the Federal Magistrate's statement that the "negligence of the agents … should not be visited against" Ms Le. There was no evidence to support a finding that Mr Oladejo's representation of Ms Le was negligent. First, as we have seen, there was no evidence that he failed to inform her that the Tribunal would convene a further hearing if requested to do so. Secondly, there is no evidence that Mr Oladejo failed to advise her competently and act on her instructions. Thirdly, there is no evidence about the nature of the evidence that the remaining witnesses would have given. Presumably, Mr Oladejo and Ms Le knew the nature of the evidence they would give; and, having regard to this, Mr Oladejo's advice and, perhaps, other considerations, Ms Le decided not to request the Tribunal to reconvene. I would not infer from Mr Oladejo's statements and conduct before the Tribunal that he did not act in his clients' interests. His Honour criticized his approach as "obsequious". Whilst the transcript shows that Mr Oladejo was respectful, even deferential, minds might reasonably differ as to whether or not this was, in the circumstances, appropriate or excessive. Even if Mr Oladejo was excessively respectful or deferential, it does not follow that he was negligent in his representation of Ms Le. Accordingly, in so far as his Honour found that Mr Oladejo was negligent, he was in error. For the reasons stated, the third ground of the Minister's appeal was made out to this extent.
59 Since there was no basis to impute negligence to Mr Oladejo, this is not a suitable occasion to consider whether relief would be available if it were shown that a review applicant lost an opportunity to present evidence on account of an adviser's negligence: for a discussion of the question, see French J's discussion in Minister for Immigration and Multicultural Affairs v SZFDE (2006) 154 FCR 356 ("SZFDE") at 383-392. It suffices to note that, as his Honour said, in a passage subsequently referred to with approval by the High Court, there are sound reasons of policy why a person whose conduct before an administrative tribunal has been affected, to the detriment of that person, by bad or negligent advice or some other mishap should not be heard to complain that the detriment vitiates the decision: SZFDE at 399 referred to in SZFDE v Minister for Immigration and Multicultural Affairs [2007] HCA 35 at [53] per Gleeson CJ, Gummow, Kirby, Hayne, Callinan, Heydon, and Crennan JJ. For the reasons stated, I would say no more about the other arguments that arose under the third and fourth grounds of appeal.
60 This takes me to the sixth of the Minister's grounds on the hearing of the appeal. On the one hand, the authorities establish that the Tribunal has no general obligation to initiate enquiries or to make out an applicant's case for him or her. These authorities stretch back over the life of the Tribunal: see, for example, Minister for Immigration and Multicultural and Indigenous Affairs v SGLB (2004) 207 ALR 12 at 21-22 per Gummow and Hayne JJ (with whom Gleeson CJ agreed) and 49 per Callinan J; Minister for Immigration and Multicultural and Indigenous Affairs v VSAF [2005] FCAFC 73 at [20] per Black CJ, Sundberg and Bennett JJ; SBBA v Minister for Immigration and Multicultural and Indigenous Affairs [2003] FCAFC 90 ("SBBA") at [8] per Weinberg, Stone and Jacobson JJ; Mohammed v Minister for Immigration and Multicultural and Indigenous Affairs [2005] FCAFC 47 at [24] per Moore, North and Emmett JJ; SJSB v Minister for Immigration and Multicultural and Indigenous Affairs [2004] FCAFC 225 at [16] per Ryan, Jacobson and Lander JJ; WAGJ v Minister for Immigration and Multicultural and Indigenous Affairs [2002] FCAFC 277 at [25] per Heerey, RD Nicholson and Mansfield JJ; NBDF v Minister for Immigration and Multicultural Affairs [2006] FCA 1355 at [24]-[25] per Branson J; Tide Sequence Industries Pty Ltd v Minister for Immigration and Multicultural and Indigenous Affairs (2005) 145 FCR 155 at 174 per Conti J; Hong v Minister for Immigration and Indigenous Affairs [2004] FCA 1308 at [40] per Finn J; NAYU v Minister for Immigration and Multicultural and Indigenous Affairs [2004] FCA 528 at [20]-[21] per Jacobson J; Rahman v Minister for Immigration & Multicultural Affairs [2000] FCA 1277 ("Rahman") at [29] per French J; Minister for Immigration and Multicultural Affairs v Anthonypillai (2001) 106 FCR 426 ("Anthonypillai") at 445 per Heerey, Goldberg and Weinberg JJ; Kabir v Minister for Immigration and Multicultural Affairs (2001) 184 ALR 295 at 305-306 per Katz J; Re Minister for Immigration and Multicultural Affairs; Ex parte Cassim (2000) 175 ALR 209 at 212-213 per McHugh J; Minister for Immigration and Ethnic Affairs v Singh (1997) 74 FCR 553 at 560-561 per Lee J; and Prasad v Minister for Immigration and Ethnic Affairs (1985) 6 FCR 155 ("Prasad") at 169-170 per Wilcox J. On the other hand, there is authority for the limited proposition that, in certain rare or exceptional circumstances, the Tribunal's failure to enquire may ground a finding of jurisdictional error because the failure may render the ensuing decision manifestly unreasonable in the sense used in Associated Provincial Picture Houses v Wednesbury Corporation [1948] 1 KB 223 ("Wednesbury Corporation").
61 In Wednesbury Corporation at 230, Lord Greene MR summarised what he saw as a fundamental common law principle when he said "[i]t is true to say that, if a decision on a competent matter is so unreasonable that no reasonable authority could ever have come to it, then the courts can interfere". He added that "to prove a case of that kind would require something overwhelming". A finding of jurisdictional error on the ground of unreasonableness is rare compared with other grounds: see Applicant M17 of 2002 v Minister for Immigration and Multicultural and Indigenous Affairs [2003] FCA 1364 at [29] per North J. It is sometimes said that there must be something exceptional about the case to attract the ground.
62 Although the position in Australia may differ from that in England, the decision in Wednesbury Corporation would support the proposition that an exercise of power that is unreasonable in this sense may ground a finding of jurisdictional error. In Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323 at 352, McHugh, Gummow and Hayne JJ held that the concept of jurisdictional error relevant in the present context derives from the general law, as explained in Craig v The State of South Australia (1995) 184 CLR 163 at 179. Craig did not refer expressly to Wednesbury unreasonableness, but the High Court accepted that the list of errors to which Craig referred was not exhaustive. In any event, the reference in Craig to the fact that, in some circumstances, erroneous findings or mistaken conclusions provide a ground of error may cover this form of error. This would be consistent with earlier authoritative statements: see Parramatta City Council v Pesell (1972) 128 CLR 305 at 323 per Menzies, 327 per Gibbs J and 332 per Stephen J; Attorney-General (New South Wales) v Quin (1990) 170 CLR 1 at 35-36 per Brennan J; Minister for Aboriginal Affairs v Peko-Wallsend Ltd (1986) 162 CLR 24 ("Peko-Wallsend") at 41 per Mason J and the authorities there mentioned; Minister for Immigration and Multicultural Affairs v Eshetu (1999) 197 CLR 611 at 626-627 per Gleeson CJ and McHugh J, 640-641 per Gaudron and Kirby JJ, 648-657 per Gummow J, 669-673 per Callinan J; Abebe v Commonwealth (1999) 197 CLR 510 at 554 per Gaudron J, 583-584 per Kirby J (but see 654, 656-657 per Gummow J); Corporation of the City of Einfield v Development Assistance Commission (2000) 199 CLR 135 at 152-154 per Gleeson CJ, Gummow, Kirby, and Hayne JJ; Re Minister for Immigration and Multicultural Affairs Ex parte Lam (2003) 214 CLR 1 at 23 per McHugh and Gummow JJ; Re Minister for Immigration and Multicultural Affairs; Ex parte Applicant S20/2002 (2003) 198 ALR 59 at 62 per Gleeson CJ, 67 and 76 per McHugh and Gummow JJ and 90-91 per Kirby J.
63 The concept of vitiating unreasonableness has been extended to the manner in which a decision was made. Thus, a failure by a decision-maker to obtain important information on a critical issue, which the decision-maker knows or ought reasonably to know is readily available, may be characterized as so unreasonable that no reasonable decision-maker would proceeded to make the decision without making the enquiry: see Prasad at 169-170 per Wilcox J; Videto v Minister for Immigration and Ethnic Affairs (1985) 8 FCR 167 ("Videto") at 178 per Toohey J; Luu v Renevier (1989) 91 ALR 39 ("Luu v Renevier") at 47-50 per Davies, Wilcox and Pincus JJ; Detsongjarus v Minister for Immigration and Ethnic Affairs (1990) 21 ALD 139 ("Detsongjarus") at 143 per Pincus J; Rahman at [30] per French J; Tickner v Bropho (1993) 40 FCR 183 at 197-198 per Black CJ; Ahamed v Minister for Immigration and Multicultural Affairs [2000] FCA 1325 at [12] per French J; Yang v Minister for Immigration and Multicultural and Indigenous Affairs (2003) 132 FCR 571 ("Yang") at 579 per Ryan and Finkelstein JJ. This proposition is also discussed in other cases, such as Li v Minister for Immigration and Multicultural Affairs (1997) 74 FCR 275 at 288 per Foster J and Minister for Immigration and Ethnic Affairs v Teoh (1995) 183 CLR 273 at 289-90 per Mason CJ and Deane J and 321 per McHugh J. In this circumstance what vitiates the decision is the manner in which it was made. Since this is a limited proposition, it does not conflict with the larger statement that the Tribunal is under no general duty with respect to making enquiries: see Prasad at 169-170 per Wilcox J and Azzi v Minister for Immigration and Multicultural Affairs (2002) 120 FCR 48 at 73-74 per Allsop J; but contrast SZEGT v Minister for Immigration and Multicultural and Indigenous Affairs [2005] FCA 1514 at [20]-[22] per Edmonds J.
64 Today, at least in the context of migration cases, judicial discussion of the significance of a failure to obtain further information on a critical issue ordinarily commences with Prasad. In Prasad, Wilcox J expressed the view, in obiter dictum, that it was unreasonable in the circumstances of the case (where a 'spouse' visa was at issue) not to seek out the explanations of certain inconsistencies in the material before the decision-maker. It was plain enough that explanations for the inconsistencies were readily ascertainable. Wilcox J referred to the recognised authorities and said, at 169-170, that:
"A power is exercised in an improper manner if, upon the material before the decision-maker, it is a decision to which no reasonable person could come. Equally, it is exercised in an improper manner if the decision-maker makes his decision - which perhaps in itself, reasonably reflects the material before him - in a manner so devoid of any plausible justification that no reasonable person could have taken this course, for example by unreasonably failing to ascertain relevant facts which he knew to be readily available to him. The circumstances under which a decision will be invalid for failure to inquire are, I think, strictly limited. It is no part of the duty of the decision-maker to make the applicant's case for him. It is not enough that the court find that the sounder course would have been to make inquiries. But, in a case where it is obvious that material is readily available which is centrally relevant to the decision to be made, it seems to me that to proceed to a decision without making any attempt to obtain that information may properly be described as an exercise of the decision-making power in an manner so unreasonable that no reasonable person would have so exercised it. It would follow that the court, on judicial review, should receive evidence as to the existence and nature of that information." (Emphasis added)
