Consideration and disposition
20 The appellant's complaint that the primary judge only selectively quoted from the passage from the joint judgment of Gummow and Hayne JJ in Minister for Immigration and Multicultural and Indigenous Affairs v SGLB [2004] HCA 32; 207 ALR 12 at [45] is rejected (see [26] of the primary judge's reasons for judgment). The primary judge was correct to point out that in SGLB the High Court rejected competency as a jurisdictional requirement in a Tribunal-setting.
21 The full relevant text at [45] of SGLB is as follows (emphasis added to highlight the sentence not quoted by the primary judge) (footnotes omitted):
The third alleged error presupposes that there is some competency requirement as to the satisfaction of which the Tribunal must be convinced before an applicant can take part or continue to take part in proceedings before the Tribunal. This assumption is without foundation. The Act does not provide for any such competency requirement, analogous, for example, to that of fitness to plead. Section 420(2)(a) of the Act expressly provides that the Tribunal is not bound by the rules of evidence. The phrase "the rules of evidence" is taken to include both the common law rules of evidence and the Evidence Act 1995 (Cth). The only requirements that could be described as competency requirements are that an application for review by the Tribunal can only be made by a non‑citizen who is the subject of the primary decision (by the Minister's delegate) and who is physically present in the migration zone when the application for review is made. The Act permits an application for a protection visa to be made by any person who is in Australia and who is not a citizen of Australia. That is not to deny that the rules of procedural fairness may, in particular circumstances arising in individual cases before the Tribunal, require some special steps or procedure to be followed. But there was no denial of procedural fairness in the present case
22 The primary judge was plainly aware that, depending upon the particular facts and circumstances of an individual case, procedural fairness requirements may require special steps or procedure to be adopted in order to provide procedural fairness (see, for example, [26] to [28] of his Honour's reasons for judgment). The essential point remains, however, that the primary judge considered that no such steps or procedures were required in the particular circumstances here, not the least because there was no evidence before either the AAT or the Court on judicial review to show that the appellant's medical conditions adversely affected his capacity to participate in the AAT proceeding, applying the approach which had been approved by the Full Court in BJB16. It might be noted in this respect that, although the primary judge made orders on 6 February 2019 which provided the appellant with an opportunity to file affidavit evidence in support of his judicial review application, he failed to do so. This Court is in the same position as the primary judge in not knowing what the outcome of any further inquiries might have been.
23 The appellant claims that the "special steps or procedures" in the present case "should include a threshold enquiry by the [AAT] to confirm that the applicant does indeed have capacity". There are two reasons why that submission must be rejected. First, the appellant does not identify the legal source of any such obligation. Secondly, and perhaps more significantly, as the primary judge found, there was neither any evidence, nor any suggestion by the appellant, before the AAT that he suffered from any particular ailment which impacted on his competency or capacity to participate in the proceeding. As mentioned, no copy of the transcript of the AAT proceeding was put in evidence either below or on the appeal.
24 As Gleeson CJ observed in SGLB at [19]:
Many people who appear before administrative tribunals, and many litigants in courts, including some litigants in this Court, suffer from psychological disorders or psychiatric illness. That may affect their capacity to do justice to their case. Fairness does not ordinarily require the court or tribunal to undertake a psychiatric or psychological assessment to investigate the extent to which the person in question may be at a disadvantage; and ordinarily it would be impossible to tell…
25 Contrary to the appellant's submission, the primary judge did not err in distinguishing SCAR on the basis that it arose in the context of a different statutory context. As the High Court observed in SZBEL v Minister for Immigration and Multicultural and Indigenous Affairs [2006] HCA 63; 228 CLR 152 at [26], the content of the obligation of procedural fairness is to be determined having regard inter alia to the statutory context. As was observed by Tracey J in Picard v Minister for Immigration and Border Protection [2015] FCA 1430 at [31], the Minister as an administrative decision-maker (and, it may be interpolated, that the AAT in the exercise of its review function under s 500(1)(ba)) is bound to accord procedural fairness to a person when dealing with the person's application for revocation under s 501CA(4) of the Act. That is not to say, however, that the requirements of procedural fairness will always be the same under those review processes. It is well settled that the AAT's function under s 425 is inquisitorial. Different procedures are involved in an AAT review under s 500(1)(ba).
26 That is not to deny that in conducting a review under s 500(1)(ba) procedural fairness requirements may oblige the AAT to adopt "special steps or procedure", including where there is evidence that the review applicant does not, or might not, have the capacity to participate in the proceeding. Equally, there may be sufficient material in a particular case so as to put the AAT on notice that the review applicant did not, or might not, have that capacity, which may require the AAT to inquire about the matter. It is plain from [37] of the primary judge's reasons for judgment that his Honour acknowledged these possibilities.
27 The fundamental flaw with the appellant's case, both below and on appeal, is that the appellant has not demonstrated how the evidence or the appellant's circumstances or presentation before the AAT suggested that the appellant did not, or might not, have the capacity to participate or that the material was sufficient to put the AAT on inquiry about these matters, as the primary judge explicitly found at [34], [37] and [38] of his reasons for judgment. The appellant drew the Court's attention to a "medication summary" dated 18 August 2017, which stated that the appellant had been prescribed Quetiapine medication which is recorded as "Clears your thoughts and has a calming effect". This does not advance his case having regard not only to the date of the summary (which precedes the AAT hearing by more than 12 months) but also because a subsequent medical record dated 3 January 2018 makes no reference to the appellant having been prescribed that medication at that time. Finally, and in any event, it might also be noted that the AAT had before it evidence that the appellant did not always take the medication which was prescribed for him.
28 The appellant's contention that the primary judge erred in his consideration of Allregal and Goddard Elliott is rejected. As the Minister pointed out, the appellant has not articulated why the primary judge erred in distinguishing those cases by reference both to their facts and to the circumstances of each of them. In the former case, there was evidence that the relevant person had conducted various other proceedings through a "next friend" which put the Court on notice that there was a history of incapacity. As to the latter case, the observations relied upon by the appellant arose in the context where a Court had been put on notice by evidence that a person may not have the capacity to manage his or her own affairs. That is not the case here.
29 The appellant takes issue with the primary judge's rejection of the argument that the principles in SZIAI applied in the present context. In SZIAI at [25], the High Court stated (emphasis added):
The duty imposed upon the Tribunal by the Migration Act is a duty to review. It may be that a failure to make an obvious inquiry about a critical fact, the existence of which is easily ascertained, could, in some circumstances, supply a sufficient link to the outcome to constitute a failure to review. If so, such a failure could give rise to jurisdictional error by constructive failure to exercise jurisdiction. It may be that failure to make such an inquiry results in a decision being affected in some other way that manifests itself as jurisdictional error.
30 We reject the appellant's complaint that SZIAI is distinguishable because "there was an obvious inquiry that should have been undertaken, and such an inquiry would clearly have yielded a useful result". As we have emphasised, it is telling that the appellant did not adduce any evidence below (or seek to have admitted on the appeal fresh evidence) which established that "a useful result" would have been accomplished if the AAT had made inquiries, namely that he lacked the requisite mental capacity to participate effectively in the AAT proceedings.
31 As found by the primary judge, the appellant has given no indication as to what "useful result" might have ensued from the inquiry he submits was required in the circumstances. At [41] his Honour observed that "the Tribunal did not have any medical material before it linking the applicant's conditions to any incapacity on his part to participate in the proceedings". This was not a case where a failure to make an enquiry amounted to a jurisdictional error. No appealable error by the primary judge is made out.
32 We reject the appellant's contention to the effect that, because the question of capacity to conduct his case arises at the time of the AAT proceeding, there was no point obtaining medical evidence after that time. This contention erroneously assumes that an appropriately qualified medical specialist would be unable to express an opinion retrospectively having regard to the entirety of the appellant's medical history and mental state.
33 An alternative way of arriving at the same conclusion in this appeal is to apply the concept of "practical injustice" which is a fundamental concern of procedural fairness (see Re Minister for Immigration and Multicultural and Indigenous Affairs; Ex parte Lam [2003] HCA 6; 214 CLR 1 at [38] per Gleeson CJ; Minister for Immigration and Border Protection v SZSSJ [2016] HCA 29; 259 CLR 180 at [82] per French CJ, Kiefel, Bell, Gageler, Keane, Nettle and Gordon JJ; Minister for Immigration and Border Protect v WZARH [2015] HCA 40; 256 CLR 326 at [57] per Gageler and Gordon JJ and Minister for Immigration and Border Protection v SZMTA [2019] HCA 3 at [38] per Bell, Gageler and Keane JJ). The concern of procedural fairness is with practical injustice, not theoretical or hypothetical injustice, which is the way in which the appellant has presented his case of procedural unfairness.
