(b) The pending hearing of V723 of 2000
100 The second ground of refusal of interlocutory relief may be discussed more briefly. We accept the submissions on this point put by counsel for the applicants. While it is true that the application for interlocutory relief traversed some of the ground that will need to be trodden by Conti J, the issues in the two proceedings are not the same. Proceeding V723 of 2000, to be considered by Conti J, is an application for penalties and compensation in respect of past alleged breaches of an industrial instrument. It is an application for enforcement of an industrial instrument. The application to Marshall J was for interlocutory orders to relieve against alleged continuing breaches of s170WG(1) of the Act. In the one case, relief is sought in respect of past conduct; in the other, relief is directed to present and future conduct. One case involves enforcement of an industrial instrument; the other involves enforcement of the WR Act itself.
101 The application for interlocutory relief having been made to him, it was the duty of Marshall J to consider that application on its merits. If he reached the issue of balance of convenience, his Honour was obliged to have regard to the whole of the circumstances of the case. In that connection it may have been relevant that Conti J was due to commence hearing proceeding V723 on 13 December, perhaps in relation to the duration of any interlocutory order that might be made. It is difficult to see, however, how the imminence of the trial could be an answer to the application. At best, it may have been a reason for deferring the hearing for a time if it was not as urgent as the applicants allege. If that course was taken, Marshall J would have needed to have borne in mind that there can be no guarantee that the hearing before Conti J will be completed within the period allocated to it, that Conti J may not deliver judgment immediately after the conclusion of the hearing and that his decision may be the subject of an appeal. As the matter will return to Marshall J, it is inappropriate for us to make any comment about the weight that might be given to any of these issues. We simply say that the imminent hearing of V723 of 2000 was not a proper basis for declining to consider, on its merits, the application for interlocutory relief in V833 of 2000.
Disposition
102 A decision to refuse an interlocutory injunction is a decision made in the discretionary jurisdiction of the Court. It is a decision that attracts the well-known principle enunciated in House v The King (1936) 55 CLR 499 at 504-505:
"It is not enough that the judges composing the appellate court consider that, if they had been in the position of the primary judge, they would have taken a different course. It must appear that some error has been made in exercising the discretion. If the judge acts upon a wrong principle, if he allows extraneous or irrelevant matters to guide or affect him, if he mistakes the facts, if he does not take into account some material consideration, then his determination should be reviewed and the appellate court may exercise its own discretion in substitution for his if it has the materials for doing so."
103 In the present case, we respectfully think Marshall J fell into two errors of law: first, in concluding he had no jurisdiction to grant the interlocutory relief sought by the applicants; and, second, in holding the issues that were raised by the application for interlocutory relief were the same as those expected to be determined in proceeding V723 of 2000 and that it was therefore appropriate to dismiss the application in any event. That being so, it is appropriate, in proceeding V833 of 2000, to grant the applicants leave to appeal, and to allow the appeal. In our view leave to appeal is appropriate because, as a result of the errors of law, the applicants were deprived of their entitlement to have their application for interlocutory relief heard on the merits.
104 Although we have before us the whole of the material that was before Marshall J, it is not desirable for us to determine the application for interlocutory relief. Marshall J heard argument on all the issues germane to that application. We have not had that advantage. Furthermore, he has a greater knowledge of the facts of the case than we can readily obtain. We think it preferable that the matter be remitted to his Honour for determination of the application for interlocutory relief in the light of the conclusions expressed in these reasons. Having regard to the nature of the application, it is important that this be done as a matter of urgency. His Honour may wish to allow the parties a brief time, perhaps a day or so, to make any submissions they wish concerning matters arising out of these reasons. However, subject to that, we are of the opinion the application for interlocutory orders should be determined without further ado.
105 Marshall J has not yet expressed any view as to whether there is a serious question to be tried, concerning the allegation of duress, or as to the strength of that allegation. Nor has he yet dealt with the balance of convenience, other than by referring to the planned hearing before Conti J. But, of course, there are other matters relevant to the balance of convenience. Some of them are likely to have been raised, or will be raised, by O'Connor; including, presumably, the risk and inconvenience of the company being out of pocket during the period that must elapse between the date of commencement of any interlocutory injunction and the final hearing of V833 of 2000. Other matters are likely to have been raised, or will be raised, by the applicants. Without pretending to be exhaustive, they are likely to include the undertaking as to damages offered by AMIEU and the financial situations of the various employee applicants. There may be significant differences between the situations of various applicants; if so, it may be necessary for Marshall J to consider the position of each individual applicant. That may result in differences, perhaps significant differences, in the relief (if any) that is appropriate to be granted to particular applicants. And, of course, there will not necessarily be a close correlation between the relief appropriate to be granted to a particular applicant and the benefits that would have been received by that applicant under the 1992 agreement. If Marshall J considers it appropriate to do so, he may make an order in favour of any particular applicant that is framed in terms similar to that sought in the Application. However, if he considers it inappropriate to take this course, he may formulate his orders in a different way.
106 While these reasons were in course of preparation we received a letter from the solicitors for O'Connor drawing the Court's attention to the fact that, on 21 November 2000, after the hearings before us, the AIRC had made a new award, the Federal Meat Industry (Processing) Award 2000. The solicitors provided us with copies of the award. We note that it varies the 1996 award by deleting all clauses, schedules and appendices and inserting new provisions. In effect, it is a new award. However, it appears to be, like the 1996 award, a minimum rates award which has "safety net" conditions. It is stated to commence to operate from 1 November 2000 and to bind AMIEU, its officers and workers, and the National Meat Association of Australia ("NMAA") and its members in respect of relevant classifications.
107 Apparently O'Connor is now a member of the NMAA. Accordingly, the solicitors argue this award regulates the terms and conditions of the employment of AMIEU members at the abattoir. They say s148 of the WR Act applies. The solicitors seek to distinguish the Full Court's decision [2000] FCA 1197, in relation to the application of the 1996 award to the abattoir, on the basis that the Full Court held it was material that O'Connor was not a member of NMAA when the 1996 award was made.
108 The Full Court did so hold at para 48. However, this was only one of three grounds advanced by AMIEU for the submission that the 1996 award had no application: see para 47. Having regard to the view it took about the first ground, the Full Court did not need to deal with the other two grounds. Those grounds may arise if O'Connor contends that the existence of the new award is a reason why Marshall J should conclude that there is not a serious question to be tried in support of the applicant's claim for interlocutory relief in V833 of 2000. We do not wish to make any comment as to whether such a contention would have merit.
109 The orders we propose to make in proceeding V671 of 2000 (the appeal in the consolidated first instance proceeding V489 of 1999 and V650 of 1999) are as follows:
(i) the appeal be allowed;
(ii) the answer to preliminary question (b) given by Marshall J on 16 June 2000 be set aside.
110 In proceeding V833 of 2000 we will order:
(i) leave be granted to appeal against the decision of Marshall J made on 14 November 2000 refusing the applicants' application for interlocutory relief;
(ii) the appeal be allowed and the decision set aside;
(iii) the application for interlocutory relief be remitted to Marshall J for determination according to law.
