S56/03
48 We turn now to the issue of whether the majority misconceived its function under s 45 of the Act.
49 In respect of an "appeal" under s 45(1)(b) of the Act that is an "appeal" against an order made under Part VIA, s 170JF(2) in Part VIA provides as follows:
"For the avoidance of doubt, an appeal to a Full Bench under section 45 in relation to an order made by the Commission under Subdivision B of Division 3 may be made only on the grounds that the Commissioner was in error in deciding to make the order."
50 An order made under subdiv B of Div 3 includes an order made under s 170CH of the Act. Under s 170CH(1), on completion of an arbitration under s 170CG, the Commission is authorised to make an order under s 170CH(3), (4) or (6) if it has determined that a termination of employment was "harsh, unjust or unreasonable". It is a discretionary power that becomes available under s 170CH(2) if the Commission is satisfied, by having regard to all the circumstances of the case including those specified in the subsection, that the remedy ordered is appropriate.
51 We repeat that the majority did not state, in terms, that Commissioner Hodder had erred in deciding to make the orders that he made under s 170CH of the Act. The majority did not find that Commissioner Hodder was not authorised by the Act to make such orders. To the contrary, the majority confirmed that the pre‑condition to the making of such orders had been satisfied, namely, a determination made that the terminations of employment of the retrenched employees had been harsh, unjust or unreasonable.
52 The prosecutors submitted that the majority, having failed to identify any error on the part of Commissioner Hodder, whether in respect of his finding that the employer's actions were "harsh, unjust and unreasonable", or his determination that reinstatement was appropriate, exceeded its jurisdiction by purporting to set aside the remedial orders that he made, and substituting its own remedial orders. They submitted that there was no occasion or warrant for the exercise by the Full Bench of the power to "make an award, order or decision dealing with the subject matter of the decision or act concerned", pursuant to s 45(7)(b). They noted that leave had been sought, but not granted, to appeal directly against the remedial orders made by Commissioner Hodder. They acknowledged, however, that in truth little turned upon that as leave was granted to appeal against the orders made, and they essentially went to reinstatement.
53 Alternatively, the prosecutors submitted that if it had been open to the Full Bench to substitute its own remedial orders for those of Commissioner Hodder, the majority erred in having regard to irrelevant considerations, and failing to have regard to relevant considerations that it was bound to take into account. They described the "irrelevant considerations" in somewhat unorthodox terms. These were whether the selection process, applied consistently and without bias, might have identified some or all of the prosecutors for redundancy, the adoption of an inappropriate standard of proof, and possibly a reversal of the onus of proof as well. The relevant considerations not taken into consideration were said to be the fact that the prosecutors were entitled not to lose their employment save in a manner sanctioned by law, and the requirement, pursuant to s 170CH(2), that the length of the employees' service with the employer be taken into account. In addition, it was submitted that the "last on/first off" principle, a term of the contract of employment of each prosecutor, had to be taken into account under s 170CH(2)(e) as a matter that the Commission "considers relevant".
54 Finally, the prosecutors submitted that the majority, having determined that the terminations of employment were "harsh, unjust and unreasonable", purported to exercise the power conferred upon the Commission by s 170CH(1). However, before doing so, it was necessary for the Full Bench, by reason of ss 170CH(2) and 170CH(7), to be satisfied of those matters for which those sub-sections provide. These included the matters set out in s 170CH(2)(b) and (e), and also the matters set out in s 170CH(7)(b) and (e), namely "the length of the employee's service with the employer" and "any other matter that the Commission considers relevant".
55 Pacific Coal submitted that it was manifest that the majority had concluded, if not expressly then at least tacitly, that Commissioner Hodder had fallen into appealable error. In advancing that submission, it acknowledged, as it was bound to, that an appeal under s 45 was by way of rehearing, and not a hearing de novo. Accordingly, the Full Bench could exercise the power to quash or vary a decision of the Commission under s 45(7) only if there was error in the order or decision appealed from.
56 These principles derive from the decision of the High Court in Coal and Allied Operations Pty Ltd v Australian Industrial Relations Commission (2000) 203 CLR 194. In a joint judgment dealing with the construction of s 45, Gleeson CJ, Gaudron and Hayne JJ observed at 202‑204:
"[11] It was pointed out in Brideson [No 2] that "the nature of [an] appeal must ultimately depend on the terms of the statute conferring the right [of appeal]". The statute in question may confer limited or large powers on an appellate body; it may confer powers that are unique to the tribunal concerned or powers that are common to other appellate bodies. There is, thus, no definitive classification of appeals, merely descriptive phrases by which an appeal to one body may sometimes be conveniently distinguished from an appeal to another.
[12] It is common and often convenient to describe an appeal to a court or tribunal whose function is simply to determine whether the decision in question was right or wrong on the evidence and the law as it stood when that decision was given as an appeal in the strict sense. An appeal to this Court under s 73 of the Constitution is an appeal of that kind. In the case of an appeal in the strict sense, an appellate court or tribunal cannot receive further evidence and its powers are limited to setting aside the decision under appeal and, if it be appropriate, to substituting the decision that should have been made at first instance.
[13] If an appellate tribunal can receive further evidence and its powers are not restricted to making the decision that should have been made at first instance, the appeal is usually and conveniently described as an appeal by way of rehearing. Although further evidence may be admitted on an appeal of that kind, the appeal is usually conducted by reference to the evidence given at first instance and is to be contrasted with an appeal by way of hearing de novo. In the case of a hearing de novo, the matter is heard afresh and a decision is given on the evidence presented at that hearing.
[14] Ordinarily, if there has been no further evidence admitted and if there has been no relevant change in the law, a court or tribunal entertaining an appeal by way of rehearing can exercise its appellate powers only if satisfied that there was error on the part of the primary decision-maker. That is because statutory provisions conferring appellate powers, even in the case of an appeal by way of rehearing, are construed on the basis that, unless there is something to indicate otherwise, the power is to be exercised for the correction of error. However, the conferral of a right of appeal by way of a hearing de novo is construed as a proceeding in which the appellate body is required to exercise its powers whether or not there was error at first instance.
[15] The provision considered in Brideson [No 2] conferred power on the Commission to take further evidence, a provision which is indicative of an appeal by way of rehearing. It also required the Commission to "make such order as it [thought] fit". The latter requirement indicated that the Commission's appellate powers were not constrained by the need to identify error on the part of the primary decision-maker, but, rather, that the Commission was obliged to give its own decision on the evidence before it.
[16] The terms of s 45 of the Act are different from the terms of the provision considered in Brideson [No 2]. Unlike that provision, s 45 does not require a Full Bench of the Commission to "make such order as it thinks fit". Nor is there anything else in the terms of s 45 to suggest that the powers of a Full Bench are exercisable or, as in Brideson [No 2], are required to be exercised in the absence of error on the part of the primary decision-maker.
[17] Because a Full Bench of the Commission has power under s 45(6) to receive further evidence on appeal, an appeal under that section is properly described as an appeal by way of rehearing. And because there is nothing to suggest otherwise, its powers under sub-s (7) are exercisable only if there is error on the part of the primary decision-maker. And that is so regardless of the different decisions that may be the subject of an appeal under s 45.
[18] The Full Court was in error in thinking that the nature of an appeal under s 45 differs according to the nature of the decision under appeal. However, it was correct to hold that, in the case of a discretionary decision, the exercise by a Full Bench of the Commission of its powers under s 45(7) depends on the decision at first instance being attended by appealable error." (footnotes omitted).
57 Pacific Coal invited the Court to consider carefully the events that had led up to the hearing of the appeal by the Full Bench. An earlier Full Bench, which included Senior Deputy President Kaufman and Commissioner Smith, both members of the Full Bench whose decision is presently impugned, had concluded that it was seriously arguable that appealable error had been demonstrated. Moreover, voluminous submissions had been filed by both parties directed to the question whether Commissioner Hodder had fallen into appealable error in making the reinstatement order. It was inconceivable, given those circumstances, and the experience of Senior Deputy President Watson and Commissioner Smith , that they had failed to appreciate the need for such error before exercising the power under s 45(7).
58 Pacific Coal submitted that it was not correct to say, as the prosecutors did, that the reconstituted Full Bench "resolved the major factual issues in essentially the same way" as had Commissioner Hodder. They submitted that the findings of the majority, compared with those of Commissioner Hodder, revealed significant differences. For example, Commissioner Hodder did not accept that the business case of Pacific Coal had been made out. He stated that he did not accept that Pacific Coal had reasonable grounds, at the relevant time, capable of attracting the characterisation of "genuine" operational requirements of its business as a reason for terminating the employment of the former employees. By contrast, the majority found that there was an operational requirement on Pacific Coal to reduce the size of its workforce, and that the business case was made out. However, the majority found that it was incumbent upon them to determine whether there existed a valid reason for the selection of the former employees for redundancy.
59 Pacific Coal further submitted that Commissioner Hodder had been far more critical of the PER system than was the majority. Indeed, he found that there was a conspiracy attached to the use of the blacklist, a conclusion that the majority did not reach. They simply found that there were "areas of concern", but that these did not, of themselves, justify a conclusion that the employer had not provided reasonable responses in the approach taken as a whole. Indeed, the majority concluded:
"This is not a case where the evidence is so overwhelming that the wrong persons were selected for redundancy so as to give us reason to find that the employer's actions were only designed to reach a result that would otherwise be impermissible."
60 Pacific Coal submitted that once the Full Bench arrived at conclusions upon the statutory criteria which were significantly different from those of Commissioner Hodder, it necessarily followed that error was demonstrated. Merely because the majority did not declare, in terms, that it had "found error" was of no consequence. The Court should infer that the Full Bench had concluded that the Commissioner's decision was attended by appealable error, and therefore decline the relief sought by the prosecutors.
61 In support of this submission, Pacific Coal drew attention to the decision of the Full Court in Sammartino v Foggo (1999) 93 IR 52. There it was said that in an appeal under s 45 of the Act, the Commission:
"… will find an error of law or an error of fact if the Commission reaches a different conclusion on the facts or on the law than that arrived at by the primary decision-maker."
62 Pacific Coal also referred to Miller v Australian Industrial Relations Commission (2001) 108 FCR 192 in which a Full Court had observed that there was "substantial force" in an argument that was based, at least in part, upon Sammartino. The Full Court in Miller regarded the "discretion" conferred upon the Commission as, in truth, a narrow one which could be challenged for error upon normal appellate principles. It also held that the Full Bench, in refusing leave to appeal, had erred in applying the test of whether the decision at first instance was reasonably open to the Commission. The correct test was whether it was seriously arguable that the Commission had actually been wrong. Accordingly, writs of certiorari and mandamus issued.
63 Returning to the present case, Pacific Coal submitted that although the majority did not disagree with the determination by Commissioner Hodder that the dismissals had been "harsh, unjust or unreasonable", the findings upon which that determination was based were very different. This both demonstrated error, and called for a review of the remedies originally granted. However, if contrary to that submission, this Court were to hold that the majority had simply substituted its view of the matter for that of Commissioner Hodder, without any finding of error on his part, the respondents submitted that the decision of the Full Bench should be quashed entirely and not simply that part of the reasoning of the majority that went to reinstatement. It would follow that no part of that decision could be sustained. It would be inappropriate, and unjust, to allow that part of the majority's decision that affirmed Commissioner Hodder's determination to stand, but not its decision to set aside his order that the employees be reinstated.
64 Pacific Coal did not refer to any authority on this point. The matter is canvassed, in a broad sense, in recent High Court decisions arising under the Migration Act 1956 (Cth). See generally Minister for Immigration and Multicultural Affairs v Thiyagarajah (2000) 199 CLR 343; Minister for Immigration and Multicultural Affairs v Bhardwaj (2002) 209 CLR 597 at 612‑617 per Gaudron and Gummow JJ, 633‑634 per Kirby J and 643 per Hayne J, and Plaintiff S157/2002 v Commonwealth (2003) 195 ALR 24. However, none of these cases is, in any way, determinative.
65 Pacific Coal submitted that the alternative case advanced by the prosecutors, namely the claim that the majority had taken into account irrelevant considerations, or failed to take into account a relevant consideration, was without substance. They submitted that having found that the dismissals were "harsh, unjust and unreasonable", the Full Bench had a discretion as to whether or not to grant any remedy. The scope of that discretion was to provide such of the remedies, if any, as are set out in s 170CH(3), (4) or (6) as the Full Bench considered appropriate. Section 170CH(2) established a threshold in a case in which the Commission was minded to provide a remedy, but did not provide an exhaustive checklist of factors that the Commission had to take into account before deciding whether or not to grant a remedy.
66 Pacific Coal next submitted that this construction of s 170CH was supported by reference to the text of the Act, and considerations of general principle. They submitted that the majority had been entitled to have regard to the matters set out in [60]‑[61] of the reasons for decision, those being the matters identified by the prosecutors as irrelevant considerations. Indeed, it was submitted that it would have been perverse had the Full Bench not taken those matters into account. Given that the business case for a reduction in staffing had been made out, it was submitted that it would be extraordinary to hold that the Commission should not have considered the practical implications of returning the sixteen former employees to jobs that no longer existed.
67 Finally, Pacific Coal submitted that the Full Bench had not failed to take into account any matters that it was obliged to consider. The contention that the prosecutors were contractually entitled to continue their employment because of the "last on/first off" principle was plainly relevant to the question whether they were harshly, unjustly or unreasonably dismissed. That was the proper place to consider that contention, not at the point of determining whether they should be reemployed rather than compensated.
68 As noted, Pacific Coal argued strenuously that it would be wrong to quash the orders made by the Full Bench while, at the same time, leaving the appeal from Commissioner Hodder unresolved. That would mean that the orders having practical effect would be those of Commissioner Hodder, even though the Full Bench had rejected a significant aspect of his reasoning. Such an outcome would be unjust.
69 However, Pacific Coal submitted that if, contrary to its primary submission, this Court were minded to remit the matter on any such limited basis, it should consider, by way of defence, the respondents' contentions in "S509/03", filed on 25 November 2003, in support of a case that the primary determination of the majority of the Full Bench should also be set aside by reason of jurisdictional error.
70 Whether or not Commissioner Hodder's discretion miscarried when he ordered reinstatement was, in our view, a live issue before the Full Bench. Of course, the Full Bench was not exercising judicial power: Construction, Forestry, Mining and Energy Union v Australian Industrial Relations Commission (1998) 89 FCR 200 per Spender, Moore and Branson JJ at 226‑227. However, it was required by the terms of s 170JF(2) to determine whether the orders made by Commissioner Hodder, including that for reinstatement, involved appealable error, in that the exercise of the discretion to make those orders was affected by error of the type described in House v The King (1936) 55 CLR 499, further explained by Mason and Deane JJ in Norbis v Norbis (1985‑1986) 161 CLR 513 at 518‑519:
"The sense in which the terms "discretion" and "principle" are used in these remarks needs some explanation. "Discretion" signifies a number of different legal concepts: see, e.g., the discussion in Pattenden, The Judge, Discretion, and the Criminal Trial (1982), pp. 3-10. Here the order is discretionary because it depends on the application of a very general standard - what is "just and equitable" - which calls for an overall assessment in the light of the factors mentioned in s. 79(4), each of which in turn calls for an assessment of circumstances. Because these assessments call for value judgments in respect of which there is room for reasonable differences of opinion, no particular opinion being uniquely right, the making of the order involves the exercise of a judicial discretion. The contrast is with an order the making of which is dictated by the application of a fixed rule to the facts on which its operation depends.
The principles enunciated in House v The King (1936) 55 C.L.R. 499 were fashioned with a close eye on the characteristics of a discretionary order in the sense which we have outlined. If the questions involved lend themselves to differences of opinion which, within a given range, are legitimate and reasonable answers to the questions, it would be wrong to allow a court of appeal to set aside a judgment at first instance merely because there exists just such a difference of opinion between the judges on appeal and the judge at first instance. In conformity with the dictates of principled decision‑making, it would be wrong to determine the parties' rights by reference to a mere preference for a different result over that favoured by the judge at first instance, in the absence of error on his part. According to our conception of the appellate process, the existence of an error, whether of law or fact, on the part of the court at first instance is an indispensable condition of a successful appeal."
71 As the Full Court stated in CFMEU v AIRC (1998) 89 FCR 200 at 230:
"There is nothing in the [Act] that clearly indicates that a Full Bench is, in exercise of powers conferred by s 45, intended to have some general supervisory role over the exercise of discretionary powers exercised by single members of the Commission in the absence of appellable error. That is, a supervisory role involving the exercise afresh of the discretionary power in the absence of error. Indeed the existence of the mechanisms in ss 106‑109 for referring matters to a Full Bench tells against such a construction. Those sections enable a party or the Minister to apply to have an industrial dispute, an order or award (or a related decision) or principles concerning the making or varying awards in relation to allowable award matters dealt with or reconsidered by a Full Bench or for the President to assume control of the proceeding with that ultimate effect.
Proceedings involving these matters can be heard and determined by a Full Bench which can exercise the powers that would otherwise be exercisable by a single member (or have been in relation to a matter dealt with under s 109). In that way the exercise of several of the more significant powers of the Commission can be undertaken by a Full Bench which can establish principles for the exercise of those powers more generally; as to a similar mechanism in the C & A Act, see R v Moore; Ex parte Australian Telephone and Phonogram Officers Association (1982) [148 CLR 600; 39 ALR 1]. The existence of these express provisions providing these mechanisms tells against the appellate jurisdiction arising under s 45 as being generally for the same purpose, that is, as a mechanism of general application for a Full Bench to exercise a supervisory jurisdiction in the absence of appellable error."
72 The terms of s 170JF(2) reinforce the foregoing and, in particular, remove any remaining doubt as to the nature of an "appeal" under s 45 of the Act from an order made under Part VIA of the Act: Edwards v Giudice (1999) 94 FCR 561 per Finkelstein J at 582.
73 With respect to the Full Bench, and subject only its findings at [61], the reasons provided by the majority do not seem to identify any appealable error in the exercise of discretionary power carried out by Commissioner Hodder. There is no disclosed reasoning supporting the decision of the Full Bench to uphold the appeal, and set aside the "order" of Commissioner Hodder. The Full Bench appears to have treated the power to make orders under s 170CH as a discretion that became exercisable upon the Full Bench undertaking the hearing of the "appeal" (having granted leave to appeal), without any need to demonstrate error on the part of Commissioner Hodder in making the orders that he did.
74 The fact that one member of the majority, Commissioner Smith, sat on the Full Bench that had previously held that it was seriously arguable that Commissioner Hodder's decision was affected by appealable error does not, in our view, demonstrate that the majority on the second Full Bench exercised its statutory function under s 45 in accordance with law. Nor can we draw any such conclusion from the fact that both Senior Deputy President Watson and Commissioner Smith are experienced members of the Commission, and certain to be familiar with the provisions of the Act, and much of the case law that has built up around it. It is a fact that neither is legally qualified. It cannot be assumed that, when considering the appeal, they had at the forefront of their minds the strict requirements laid down by the High Court in Coal and Allied Operations Pty Ltd v Australian Industrial Relations Commission regarding the nature of the statutory power conferred by s 45. That is particularly so given the manner in which their reasons for decision are structured, with no specific reference to any error on the part of Commissioner Hodder, no implicit finding of any such error in relation to his order for reinstatement, and a series of conclusions expressed in language redolent of an appeal conducted as a hearing de novo.
75 In our view, there is at least a distinct possibility that the majority simply overlooked the need to find appealable error before interfering with Commissioner Hodder's order for reinstatement. Indeed, if one focuses solely upon its expressed reasons for decision, that distinct possibility becomes a likelihood. The Full Bench therefore lacked jurisdiction to make the orders that it purported to make.
76 It is unnecessary, having regard to this conclusion, to deal with the alternative case propounded by the prosecutors. We should say, however, that we consider that alternative case to be tenuous, at best.
77 That raises the question of what relief, if any, should be granted. It is clear that the matter must be remitted to the Full Bench to be heard and determined according to law. The question is whether the jurisdictional error on the part of the majority requires the whole of the matter to be remitted, or whether it is appropriate to remit only that part of the decision that related to the quashing of Commissioner Hodder's order for reinstatement.
78 The prosecutors submit that the only matter that should be remitted is the remedial order. As previously noted, Pacific Coal argues that this would be grossly unfair. It says that if the decision of the majority is shown to be tainted by jurisdictional error, namely the adoption of an erroneous approach to the appellate function conferred by s 45, that error affects the entirety of its reasoning. That would include its acceptance of Commissioner Hodder's finding that the dismissals were "harsh, unjust and unreasonable".
79 In our view, the correct analysis is somewhat more complex. Assuming for present purposes that Pacific Coal's "defensive" challenge to the Full Bench's primary finding, as mounted in "S509/03" fails, a matter to which we shall turn shortly, there is no reason why that part of the appeal to the Full Bench should be held to have miscarried. There is no suggestion that the majority approached the issue whether the dismissals were "harsh, unjust and unreasonable" in a way that reveals the type of error that is apparent in its treatment of Commissioner Hodder's remedial order.
80 However, as previously indicated, it is possible that, notwithstanding the failure of the majority to say so, it did find appealable error in Commissioner Hodder's decision to order reinstatement. Whether or not that is so depends largely upon how one interprets par [61] of the majority's reasons. It would certainly have been open to the majority to find such error. To that extent, it would be open to the Full Bench to again do so, after reconsideration, provided that it applied the correct approach to its task.
81 The matter is greatly complicated by the fact that the Full Bench seems to have acted, to some degree, on the basis of further evidence received under s 45(6). When an appellate court receives further evidence, it generally does so only where certain pre-conditions are met. The ordinary requirements for the reception of fresh evidence are that the party seeking to adduce the evidence must show that reasonable diligence was exercised to procure the evidence for the trial and that it is reasonably clear that if the evidence had been available, and had been adduced, a different result would have been produced.
82 It is clear that some statutory provisions allowing for the reception of further evidence on appeal are cast in broader terms than the somewhat narrower common law restraints. See for example s 27 of the Federal Court of Australia Act 1976 (Cth), and see generally CDJ v VAJ (1998) 197 CLR 172 at 199, 201‑202 and Minister for Immigration and Multicultural Affairs v Jia Legeng (2001) 205 CLR 507. Nonetheless, it is clear that an appeal to the Full Court of the Federal Court is not an appeal stricto sensu, but is an appeal by way of rehearing: Allesch v Maunz (2000) 203 CLR 172 at 179‑182 and Cubillo v Commonwealth (2001) 112 FCR 455 at 522.
83 Under s 110(2)(b), the Commission is not bound by the rules of evidence. Indeed, under s 110(2)(c), it is required to act according to "equity, good conscience and the substantial merits of the case, without regard to technicalities and legal forms". It is entitled, in the exercise of its discretion, to determine its own procedure: The Queen v Alley; Ex parte NSW Plumbers & Gasfitters Employees' Union (1981) 153 CLR 376 at 380.
84 In one sense, there are difficulties with the proposition that an appellate tribunal can receive further evidence, arguably almost at will, yet be limited in the exercise of its appellate powers to correcting appealable errors. However, the High Court has held, in Coal and Allied Operations Pty Ltd v Australian Industrial Relations Commission,that the powers of the Full Bench are so limited. Indeed, it treated the fact that the Full Bench had a power to receive further evidence as a clear indication that an appeal under s 45 was by way of rehearing, and not a hearing de novo. Almost by definition, when evidence is received on appeal that was not led at first instance, and that evidence is of crucial importance, the outcome may be affected without appealable error having been established. In other words, the decision at first instance may have been correct on the evidence as it stood, but no longer be appropriate in the face of the further evidence.
85 Despite the difficulties raised by s 45, and the interpretation accorded to that section by various appellate courts, jurisdictional error having been established, the prosecutors are entitled to the constitutional writs sought: Re AIRC; ex parte CFMEU per Wilcox and Madgwick JJ at [63]‑[79]. Those writs are granted because the Full Bench failed to perform its statutory function according to law. That function should now be performed in relation to the remedial orders previously made, but in the light of the requirements laid down by s 45 as interpreted by the High Court.
86 In arriving at this conclusion, we are conscious of the fact that most decisions that are successfully impugned are nullified completely. However, as is noted in Aronson, Dyer and Groves Judicial Review of Administrative Action (3rd ed, 2004, Law Book Co) at 640‑643 in some cases it may be possible to sever those parts of a decision that are not tainted by jurisdictional error. So a breach of natural justice which occurs only in relation to the setting of a penalty need not result in quashing the finding of guilt: Hall v New South Wales Trotting Club Ltd [1977] 1 NSWLR 378 and Malone v Marr [1981] 2 NSWLR 894. In Re Heaney; ex parte Tunza Holdings Pty Ltd [1998] WASCA 341, certiorari quashed a mining warden's decision, but left him free to make a decision on elements not yet determined without having to go to another hearing. There are many other examples of severability of appellate tribunals' decisions including R v Marshall; ex parte Baranor Nominees Pty Ltd [1984] VR 211 (invalid backdating of a wage increase) and Bread Manufacturers of New South Wales v Evans (1981) 180 CLR 404 (a clause in a new price fixing ruling revoking former rulings).
87 It is interesting to note that in Re Media, Entertainment and Arts Alliance; Ex parte Arnel (1994) 179 CLR 84, the High Court held that a decision by the Commission amounted to a constructive failure to exercise jurisdiction and was reached in breach of the requirements of procedural fairness. The Court ordered that writs of prohibition, certiorari and mandamus issue. The writ of certiorari operated to quash the impugned decision only to the extent that it affected the entitlement of the applicants to put a case for leave to intervene with respect to differential rates for junior employees. In other words, the writ did not quash the decision in its entirety, but only that part that involved jurisdictional error. Severance was at least tacitly recognised as available.
88 In the present case, it is not difficult to distil from the impugned decision of the majority two quite separate and discrete parts. The first involves the analysis of whether the terminations were "harsh, unjust and unreasonable". The second raises the question of remedial orders. The jurisdictional error made by the majority in relation to the second issue does not of itself taint its finding on the first issue. There is no reason, in principle, why the Full Bench should be required to reconsider a part of its decision which has never been shown to be in error, whether it be jurisdictional or otherwise.
