the procedural fairness issue
31 The Minister's written submissions conceded that the letter sent to the applicant on 13 December 2001 was apt to mislead her about the procedure the MRT intended to follow. This concession was clearly correct, as the letter told the applicant that if the MRT was unable to make a decision in her favour, having regard to her written responses to the issues raised, it would give her an opportunity to appear at a hearing. That opportunity was never provided.
32 Subject to one qualification, the Minister's written submissions also accepted that the fact that the letter was apt to mislead the applicant "could constitute a denial of procedural fairness in an appropriate case". The qualification was that the applicant at that stage had adduced no evidence that she had been misled or that she would have availed herself of the opportunity to appear before the MRT.
33 Doubtless alerted by the Minister's written submissions to the evidentiary gap, Mr Reilly read an affidavit from the applicant to the effect that she had understood from the letter that she would have an opportunity to attend an oral hearing before the MRT and that she would in fact have availed herself of that opportunity. The applicant was cross-examined, but I accept her affidavit evidence. Accordingly, had no further arguments been advanced by the Minister, the applicant would have made out her case that, independently of the effect of s 474(1) of the Migration Act, she had been denied procedural fairness by the MRT.
34 In the course of oral argument, however, Mr Lloyd advanced a further argument on behalf of the Minister. He submitted that, on the applicant's evidence, there was nothing that she wished to put to the MRT on the factual questions raised in the letter, beyond the matters in her written response. Accordingly, so Mr Lloyd argued, the applicant had not shown that the MRT would have come to any different conclusion. It followed that the applicant had not established that the MRT had breached its obligation of procedural fairness or, alternatively, that she should be denied relief on discretionary grounds.
35 The present claim is for relief pursuant to s 39B(1) of the Judiciary Act, the language of which mirrors s 75(v) of the Constitution. Mr Lloyd's argument requires reference to the High Court's decision in Re Refugee Review Tribunal, Ex parte Aala (2000) 204 CLR 82, which concerned a claim for constitutional writs brought in the original jurisdiction of the High Court pursuant to s 75(v) of the Constitution. The members of the Court seem to have taken two approaches to the question of whether prohibition lies for an apparent breach of the rules of natural justice, in a case where the decision maker might have reached the same result even if there had been no breach.
36 Gaudron and Gummow JJ (with whom Gleeson CJ agreed) adopted as correct (at 106) the statement of Gibbs CJ in R v Ross-Jones; Ex parte Green (1984) 156 CLR 185, at 194:
"If, therefore, a clear case of want or excess of jurisdiction has been made out, and the prosecutor is a party aggrieved, the writ will issue almost as of right, although the court retains its discretion to refuse relief if in all the circumstances that seems the proper course."
Gaudron and Gummow JJ said that this statement should be accepted as the correct general approach to the exercise of the original jurisdiction in matters in which a writ of prohibition is sought against an officer of the Commonwealth pursuant to s 75(v) of the Constitution. Their Honours took the expression "want or excess of jurisdiction" in Gibbs CJ's judgment to include the consequences of failure to observe the rules of natural justice in the exercise of a power or authority conferred by statute.
37 Gaudron and Gummow JJ acknowledged that relief might be refused in a particular case on the ground of lack of utility, as where the decision-maker is bound by the governing statute to refuse the application irrespective of any question of procedural fairness. Their Honours observed, however, that (at 109):
"the conditioning of a statutory power so as to require the provision of procedural fairness has, as its basis, a rationale which differs from that which generally underpins the doctrine of excess of power or jurisdiction. The concern is with observance of fair decision-making procedures rather than with the character of the decision which emerges from the observance of those procedures. Unless the limitation ordinarily implied on the statutory power is to be rewritten as denying jurisdictional error for 'trivial' breaches of the requirements of procedural fairness, the bearing of the breach upon the ultimate decision should not itself determine whether prohibition under s 75(v) should go. The issue always is whether or not there has been a breach of the obligation to accord procedural fairness and, if so, there will have been jurisdictional error for the purposes of s 75(v)."
This passage suggests that a denial of procedural fairness may be treated differently from other cases of excess of power or jurisdiction in that the relationship between the breach and the ultimate decision should not of itself determine whether prohibition should be granted. Nonetheless, their Honours recognise that if an alleged breach of procedural fairness is trivial, in the sense that it occasions no injustice, the correct conclusion may be that, in the circumstances, the practical requirements of procedural fairness have been observed.
38 Gaudron and Gummow JJ ultimately held in Ex parte Aala that an inaccurate statement by the Tribunal that it had read all papers from the prosecutor's previous application, upon which the prosecutor had relied in deciding not to give evidence at a second hearing, justified the grant of relief under s 75(v) of the Constitution. Their Honours quoted with approval observations by Lord Diplock in Mahon v Air New Zealand Ltd [1984] AC 808, at 821, as follows:
"The second rule [of natural justice] requires that any person represented at the inquiry who will be adversely affected by the decision to make the finding should not be left in the dark as to the risk of the finding being made and thus deprived of any opportunity to adduce additional material of probative value which, had it been placed before the decision-maker, might have deterred him from making the finding even though it cannot be predicted that it would inevitably have had that result." (Emphasis in original.)
39 Kirby J in Ex parte Aala approached the question in a somewhat different way. His Honour said this (at 130-131):
"Once the applicable breach is proved, the victim of the breach is ordinarily entitled to relief. It is only where an affirmative conclusion is reached, that compliance with the requirements of procedural fairness 'could have made no difference' [Stead v State Government Insurance Commission (1986) 161 CLR 141, at 145] to the result, that relief will be withheld. This Court has emphasised that such an outcome will be a rarity. It will be 'no easy task' to convince a court to adopt it. This will especially be so where, as here, 'the issue concerns the acceptance or rejection of the testimony of a witness at the trial'. In this case, what was at stake could hardly have been more important, being the credibility of the prosecutor and whether his statements to the second Tribunal were, as it concluded, in a critical respect, a 'concoction' and so should be rejected. Many, if not most, cases of this kind turn on the assessment of the credibility of the applicant for refugee status. There are already enough obstacles to be overcome. Adding to these a mistake affecting the credibility of the applicant is not tolerable." (Some footnotes omitted.)
On this approach, it would seem that relief may be denied in respect of a breach of the requirements of procedural fairness if the court affirmatively concludes that compliance with those requirements could have made no difference to the outcome. However, the test adopted by Kirby J to determine whether relief should be granted, founded on the reasoning of the High Court in Stead v SGIC, does not seem to differ materially from the test applied by Gaudron and Gummow JJ.
40 Callinan J's analysis in Ex parte Aala (at 153-154) is similar to that of Kirby J, as is that of McHugh J (at 122), although his Honour dissented as to the result. Hayne J (at 144) expressed general agreement with the conclusions reached by Gaudron and Gummow JJ.
41 The curious feature of the present case is that, if I have correctly identified the error of law committed by the MRT, the findings of fact unfavourable to the applicant, set out in pars [44]-[47] of the MRT's reasons, were irrelevant to the questions it was required to address. Nonetheless, those factual findings played an important part in the MRT's decision. In my view, to use the language of Lord Diplock in Mahon v Air New Zealand, the applicant was deprived of the opportunity to put probative material which might have deterred the MRT from making the unfavourable findings. If the correct approach is that adopted by Kirby J, I cannot affirmatively reach the conclusion that observance of the requirements of procedural fairness could have made no difference to the outcome.
42 Evidence was adduced in these proceedings from the applicant's husband that he had travelled to China on a Chinese passport, not on an Australian passport as the MRT found. That evidence was not before the MRT, which apparently considered the "fact" that the applicant had travelled on an Australian passport cast doubt on his account. Had the evidence been presented to the MRT, it might have reached a different conclusion as to whether the applicant or her husband could or would have taken the child back to Australia earlier than in fact happened. This in turn may have led the MRT to take a different view on other factual issues. Had a second oral hearing taken place, the husband may well have produced his Chinese passport.
43 I think it also important to recognise that had there been a second hearing before the MRT, the applicant would have had the opportunity to answer questions put to her by the MRT member. Those answers might, for example, have dissuaded the MRT from making the somewhat surprising finding that it was not satisfied that
"the nominator's bond with his mother [was] stronger than with any other person in his life".
While I do not think that this finding was relevant to the question of "serious circumstances", the MRT apparently regarded it as important.
44 Mr Lloyd submitted that the applicant's evidence in this Court showed that she would not have added anything beyond what was contained in the written submissions to the MRT following its letter of 13 December 2001. I do not think this is the correct inference from the evidence given by the applicant. She was plainly heavily reliant on her husband to present her case. There is no reason to think that he would not have encouraged her to give further evidence, as well as advancing his own account of his attempts to retrieve the nominator from China. Moreover, had there been a second hearing, it is very likely that the MRT would have asked the applicant questions on the factual issues that troubled it, not all of which were identified with precision in the letter of 13 December 2001. It is difficult to conclude that, had the applicant and her husband had a further opportunity to address the MRT's concerns, the MRT inevitably would have reached the same conclusion.
45 In my view, the applicant has established that she was denied procedural fairness by the MRT. Putting s 474(1) of the Migration Act to one side, that denial of procedural fairness would entitle her to relief under s 39B(1) of the Judiciary Act.
