Consideration
18 The relevant legal principle as to what procedural fairness requires in a case such as this was expressed by Gaudron J, with whom Dawson J agreed, in Re Coldham; Ex parte Municipal Officers Association of Australia (1989) 84 ALR 208 at 219-220 (the Architects Case), where she said:
"There is a further question: was the Commission required, as a matter of procedural fairness, to afford the parties an opportunity to be heard upon the issues directed by s 142 in the light of the construction adopted by it? Ordinarily, when a decision on a question of law will affect the nature and range of the factual matters by reference to which the matter in issue may be decided, considerations of fairness require that the parties be given an opportunity to lead evidence and make submissions by reference to the principles of law to be applied. This must be so even if the existence of the question is not apparent until the hearing has concluded. Although, of course, the fact that a hearing has taken place may have particular significance in determining whether or not the opportunity was given. As was pointed out by Deane J in Sullivan v Department of Transport (1978) 20 ALR 323 at 343, procedural fairness requires only that a party be given "a reasonable opportunity to present his case" and not that the tribunal ensure "that a party takes the best advantage of the opportunity to which he is entitled". And it is always relevant to inquire whether the party or his legal representative should reasonably have apprehended that the issue was or might become a live issue: see Re Building Workers' Industrial Union; Ex parte Gallagher (1988) 62 ALJR 81; 76 ALR 353 at 358." (bold non-italic emphasis added)
19 Her Honour expressed that statement of principle in considering whether a Full Bench of a predecessor of the Commission should have invited submissions on the proper construction of a legislative provision, against the background that a concession had been made on that matter but where the concession had not been acted upon by the Full Bench in arriving at its unexpected construction. A similar issue arose in Re Building Workers' Industrial Union; Ex parte Gallagher (1988) 76 ALR 353 in the context of the effects of a concession that had been made.
20 Different considerations may arise here, where the issue is the extent to which a party in proceedings ought to have availed itself of the opportunity to address the relevance of an enacted statutory provision, such as s 134(1)(da), in circumstances where that provision was not in force at the time of either the primary decision or the hearing of the appeal, but where the party was aware that it was open to the Full Bench to determine the appeal by way of rehearing on the evidence and submissions it had heard at a time after the provision had come into force, after it had reserved its decision, and the Full Bench was bound to apply it.
21 The Association contended that there was no procedural unfairness because United Voice was at all times on notice that the appeal to the Full Bench was to, and did, proceed on the basis of the Association's contentions that, first, the decision of the Deputy President was attended by appellable error; secondly, the Full Bench should quash the decision, if it granted permission to appeal; and, thirdly, the Full Bench, having quashed the decision, should itself decide the issues the subject of the appeal on the evidence that was already before the Deputy President and it on the re-hearing. The Association submitted that United Voice had had every opportunity during the hearing of the appeal before the Full Bench to raise any issue concerning the application of the s 134(1)(da) amendment and the admission of further evidence, but had elected not to do so. The Association also drew attention to the fact that, following the publication of the Full Bench's decision on 14 May 2014, and prior to the making of its determination, United Voice had a further opportunity to raise any issue concerning the application of s 134(1)(da), but had not done so. Finally, the Association contended that, if procedural unfairness were established, this Court should exercise its discretion to refuse the relief sought.
22 There appears to be considerable force in the Association's contention that, up to and including the hearing of the appeal below, United Voice was on notice that the Association was seeking to have the Full Bench conduct a re-hearing of the matter on the basis of the existing evidence. Furthermore, the Full Bench had reserved its decision on 18 December 2013 after affording the parties a further short opportunity to file supplementary submissions on some limited matters, and it was probable that the Full Bench would not publish its reasons or finalise the appeal before 1 January 2014. Senior counsel for United Voice acknowledged in argument that, in those circumstances, it was open to the Court to infer that United Voice was aware of the facts that the s 134(1)(da) amendment had been enacted and would commence on 1 January 2014 and then form one of the mandatory considerations that the Full Bench would have to take into account.
23 Accordingly, United Voice ought to have been aware of the possible relevance of the s 134(1)(da) amendment in the event that the Full Bench were to grant permission to appeal, uphold the appeal and then proceed to conduct a re-hearing on the evidence and material on which it had been addressed on 18 December 2013. As we have noted, the Association had made its position clear in the hearing before the Full Bench that it should proceed to re-hear the matter on that evidence and material and the submissions that had been made. In these circumstances, it is difficult to see how United Voice can justifiably complain of procedural unfairness. It was a matter for United Voice to determine whether or not it wished to adduce evidence or make submissions to the Full Bench either at the time of the hearing on 18 December 2013 on the potential relevance of the s 134(1)(da) amendment or thereafter, but it chose not to do so for reasons that it did not explain.
24 In our view, however, United Voice's complaint of procedural unfairness is unsustainable for a separate reason. That reason is that United Voice had the opportunity to raise the matters that it contended it wanted to raise once the Full Bench had published its reasons on 14 May 2014.
25 On that day, United Voice was put squarely on notice that the Full Bench had decided to uphold the appeal, conduct a re-hearing based on the existing evidence and to take into account s 134(1)(da) in doing so. Those matters were revealed in the Full Bench's reasons when they were published. At that time, those reasons also informed the parties that, although the Full Bench had taken s 134(1)(da) into account, the majority had taken the view that the result would have been the same even if the s 134(1)(da) amendment had not come into effect (see at [94]).
26 The publication of the Full Bench's reasons on 14 May 2014 did not constitute a determination to vary the Award within the meaning of item 6(3) of Sch 5 of the Transitional Act. Rather, the Full Bench at [156] of the majority's reasons directed the parties to file a draft determination to vary the Award so as to give effect to the majority's decision. It was only on 4 June 2014 that the Full Bench made a determination for the purposes of item 6(3) of Sch 5 of the Transitional Act. Item 6(3) empowered the Commission (and on appeal the Full Bench) to make a determination varying any modern award in a way that the Commission considered appropriate to remedy any issues identified in a review. The note to item 6(3) specified that any variation of a modern award had to comply with the provisions of the Fair Work Act relating to the content of modern awards. Item 6(4) made clear that the modern awards objective in s 134(1) applied to the Commission and the Full Bench when making a variation under item 6, including, for present purposes, when the Full Bench made the determination to vary the award on 4 June 2014.
27 In our opinion, United Voice was afforded an opportunity to raise any issue of procedural unfairness relating to the amendment effected by s 134(1)(da) when the Full Bench published its reasons on 14 May 2014 and directed the parties to consider and formulate the terms of a draft determination.
28 The Full Bench did not make a determination on 14 May 2014 that varied the Award. Contrary to United Voice's submission, the Full Bench was not functus officio at that date. United Voice offered no satisfactory explanation as to why it did not seek to ventilate its complaint of procedural unfairness upon becoming aware of the contents of the Full Bench's reasons and the manner in which those reasons had dealt with the issues relating to s 134(1)(da).
29 United Voice candidly acknowledged that it did not complain in these proceedings that the Full Bench had misconstrued s 134(1)(da) in giving effect to the weighing of all of the mandatory considerations in s 134(1). Rather, United Voice's grievance related exclusively to its assertion that it ought to have been allowed to address evidence and submissions to the Full Bench on the effect of the s 134(1)(da) amendment. We consider that that grievance has no substance. From the time of publication of the Full Bench's decision, it was open to United Voice to raise its complaint of procedural unfairness directly with the Full Bench. It elected not to do so.
30 In Assistant Commissioner Condon v Pompano Pty Ltd (2013) 295 ALR 638 at 681 [156], Hayne, Crennan, Kiefel and Bell JJ observed that the rules of procedural fairness do not have immutably fixed content and, as Gleeson CJ had said in Re Minister for Immigration and Multicultural and Indigenous Affairs; Ex parte Lam (2003) 214 CLR 1 at 14 [37]:
"Fairness is not an abstract concept. It is essentially practical. Whether one talks in terms of procedural fairness or natural justice, the concern of the law is to avoid practical injustice."
31 United Voice failed to establish that it did not have the opportunity on or after 14 May 2014 to present any case to the Full Bench that it wished to make in respect of s 134(1)(da) before the Full Bench made the determination on 4 June 2014 to vary the Award under item 6(3) of Sch 5 of the Transitional Act. In those circumstances, in our opinion, United Voice has not suffered any practical injustice or procedural unfairness.
32 In the circumstances, it is unnecessary for us to consider and determine the Association's alternative contentions regarding the discretion to refuse constitutional writ relief.
