DECISION
21 In my opinion, I should follow Bruning and the other two cases following it, and hold that this Court has jurisdiction to order removal of the Industrial Relations Commission proceedings.
22 I accept, as submitted by Mr. Hall, that in exercising the Court's discretion, weight should be given to the specialist expertise of the Industrial Relations Commission concerning applications under s.106. However, I think it is fair to say that this consideration has somewhat less weight in relation to claims of this size and nature, than in relation to claims more directly related to industrial relations, particularly claims which in one way or another involve industrial awards.
23 I accept also, as submitted by Mr. Hall, that weight should be given to the circumstances that there has been delay in making this application, that substantial issues have been fought and determined in the other jurisdictions, and that substantial costs have been incurred. However, there was no cross-examination of the plaintiff's solicitor, who put on an affidavit, to suggest that the delay from mid-February 1999, when the solicitors learnt of the decision in Bruning, to 29th March 1999, when cross-vesting was suggested, was in order to ascertain whether a favourable decision was to be obtained from the Industrial Relations Commission. I do not think I should infer from that delay that this is a case of forum shopping. In my opinion, the belief of both sets of solicitors that transfer was not available explains the delay to mid-February 1999; although this does not eliminate delay as a significant discretionary factor.
24 In my opinion also, it is clear that there should be no effective removal of the proceedings from the Industrial Relations Commission until the Full Bench has decided the appeal which has been brought to it; until the s.109 conciliation procedure has been completed; and until there has been an order for transfer by the Federal Court of the proceedings before it. This could give rise to further delay.
25 In my opinion, the substantial question I have to decide is whether the factors outlined above are or are not outweighed by considerations of justice and convenience in avoiding a multiplicity of proceedings.
26 If I could be confident that the proceedings in the Industrial Relations Commission would either resolve the dispute entirely, or as a practical matter greatly limit the scope of the Federal Court proceedings, I would incline against ordering removal. However, plainly Messrs. Bell and Berg do not have confidence that the Industrial Relations Commission will entirely resolve the dispute, because the whole point of their bringing two sets of proceedings is that, if they do not get what they want from the Industrial Relations Commission proceedings, they will proceed with the Federal Court proceedings. In my opinion, I have to regard that as a substantial possibility. The cases before the Industrial Relations Commission are cases concerning claims totalling more than $30 million, requiring a hearing time estimated at about three weeks by the applicants, or six to eight weeks by the respondents, and involving considerable complexity, particularly on questions of quantum; and unless the decision in the Industrial Relations Commission proceedings greatly limits the extent of subsequent Federal Court proceedings, the hearing of those proceedings would probably be of similar duration and complexity.
27 The question whether the extent of the Federal Court proceedings would be so limited depends very much on how the principles of issue estoppel would operate. In Heath at paragraphs 39-42, Austin, J. discussed awkward questions of issue estoppel that could arise in the proceedings that he was considering. Mr. Hall submitted that such awkward questions would not arise in this case, because the issues in both sets of proceedings were so similar.
28 However, it is necessary to consider what the situation will be if Messrs. Bell and Berg do not get the result they want from the Industrial Relations Commission. This may happen because of factual findings about the alleged representations or their truth, or about reliance, or about the benefits actually received, or about causation, or about quantum of loss; or because the Industrial Relations Commission considers the facts as found do not justify a variation of the agreements and/or arrangements (or sufficient variation) or the payment of money (or sufficient payment).
29 Now issue estoppel will arise only as to "the point actually decided" and "matters which were necessary to decide and were actually decided as the groundwork of the decision itself though not then directly the point at issue": R. v. Hartington Middle Quarter Inhabitants (1855) 4 E&B 780 at 794; Blair v. Curren (1939) 62 CLR 464 at 510. As Dixon, J. said in Blair at p.532: "Findings, however deliberate and formal, which concern only evidentiary facts and not ultimate facts forming the very title to rights give rise to no preclusion" These matters are discussed at paragraphs 202 and 205 in Spencer Bower & Handley, Res Judicata (3rd. Ed. 1996):
202. "The difficulty in the actual application of these conceptions", continued Dixon, J., [at p.533 in Blair ] "is to distinguish the matters fundamental or cardinal to the prior decision or judgment, or necessarily involved in it as its legal justification or foundation, from matters which, even though actually raised and decided as being in the circumstances of the case the determining considerations, yet are not in point of law the essential foundation or groundwork of the judgment". In order to make this distinction one has to inquire whether the determination was so fundamental to the decision that the latter cannot stand without it. Even where this condition is met, it is suggested by Dixon J that there is another test to pass, viz. Whether the determination is the "immediate foundation" of the decision or merely "a proposition collateral or subsidiary only, i.e. no more than part of the reasoning supporting the conclusion". A mere step in the reasoning is insufficient. What is required is a determination fundamental to the decision.
