6 The main points of the applicants' case were as follows:
(a) The Court may exercise its power as to costs " at any stage of the proceedings or after the conclusion of the proceedings " (see rule 203(1) of the Industrial Relations Commission Rules 1996 (NSW) (the " Rules ")) and may require that the costs the subject of an order for costs be " paid forthwith notwithstanding that the proceedings are not concluded " (see rule 203(2) of the Rules).
(b) The approach in previous decisions of courts and tribunals provide some guidance on the circumstances in which a cost order may be made prior to the final order for costs. Those circumstances include:
(i) A question in the proceedings has been separately determined, no issue in the trial of the balance of the proceedings overlaps with the question in the separate determination and no issue in the trial of the balance of the proceedings can cast doubt on the correctness of an order for costs (see Baramon Sales Pty Limited v Goodman Fielder Mills Limited [2001] FCA 1819 at [6]-[7]; compare Baulderstone Hornibrook at [6]; compare also Aussie Airlines Pty Limited v Australian Airlines Limited (unreported, Federal Court of Australia (Sundberg J), 5 June 1997) (BC9702375) at p2);
(ii) A question in the proceedings has been separately determined and the question was discrete from any other relief sought in the proceedings (see Charlie Brown Pty Limited v Green (unreported, Supreme Court of New South Wales (McLelland CJ in Eq), 3 July 1995) (BC9505032) at p1);
(iii) An aspect of the proceedings which has been determined is sufficiently self-contained and detached or detachable from the remainder of the proceedings yet to be heard (see Horrobin v Australia and New Zealand Banking Group Limited (unreported, Court of Appeal of New South Wales, 6 June 1997) (BC9702258) (" Horrobin ") at p9 (application for summary judgment distinct from main issues); Australian Flight Test Services Pty Limited v Minister for Industry, Science and Technology (unreported, Federal Court of Australia (O'Loughlin J), 26 April 1996) (BC9601453) at p8 (application for interlocutory relief distinct from main issues); Prebble v Australian Broadcasting Corporation (unreported, Supreme Court of New South Wales (Levine J), 11 July 1997) (BC9703240) at p3 (application concerning abuse of process distinct from main issues); Telstra Corporation Limited v First Netcom Pty Limited (unreported, Federal Court of Australia (Einfeld J), 7 May 1998) (BC9802430) at p7 (application for setting aside of subpoena and security distinct from main issues) Fiduciary Limited v Morningstar Research Pty Limited (2001) 55 NSWLR 1 (" Fiduciary ") at 4 [10]; Go Exports at [14]-[15] (application concerning payment from shipment of goods distinct from other claims in the proceedings); IGA Distribution Pty Limited v King & Taylor Pty Limited [2003] VSC 412 at [3]-[4] (application to recall witness distinct from other issues); Foyster v Foyster Holdings Pty Limited [2003] NSWSC 135 at [26] (application by members of company to represent the company distinct from other issues));
(iv) The proceedings were instituted some time previously and there is a considerable time before the proceedings will be disposed of finally (see Horrobin at p9; Allstate Life Insurance Co v Australian and New Zealand Banking Group Limited (unreported, Federal Court of Australia (Lockhart, Lindgren and Tamberlin JJ), 11 July 1995), at p2; Fiduciary at 5 [13]; Go Exports at [14]; see also UnitedGlobalCom Inc v McRann [2004] NSWIRC 16 (" UnitedGlobalCom " ) at [24];
(v) The proceedings are the subject of directions that render them, in a sense, the subject of a new beginning (see Fiduciary at 6 [18]);
(vi) A guiding factor is whether the "demands of justice" (or the "interests of justice") support the making of costs order prior to the final order for costs (see Fiduciary at 4 [7]-[8], 6 [18]; UnitedGlobalCom at [16], [24]).
(c) The "demands of justice" support the making of a costs order prior to the final order for costs:
(i) The questions of jurisdiction, power, unfairness, primary relief and alternative relief (other than compensation) have been determined pursuant to the split hearing (see Judgments No 11 and 15), those questions are discrete from the issue in the second part of the matter (the question of compensation), no issue to be determined in the second part of the matter will overlap with those questions and no issue to be determined in the second part of the matter can cast doubt on the correctness of a cost order in relation to such questions;
(ii) The issues of waiver of privilege (see Interlocutory Judgments No 3, No 6, No 7 and No 8), of joinder of Caterpillar Inc (see Interlocutory Judgment No 4), of leave to proceed against Caterpillar Inc (see Interlocutory Judgment No 5), of the joinder of the Third and Fourth Respondents (see Interlocutory Judgment No 12), of the interlocutory injunction (see Interlocutory Judgment No 9), of the dissolution of the interlocutory injunction (see Interlocutory Judgments No 12, No 13 and No 14), of further discovery (see Interlocutory Judgment No 10) and of amendments to the summons for relief (see Judgment No 15) are sufficiently self-contained and detached or detachable from the remainder of the proceedings yet to be heard;
(iii) The matter was instituted some time previously (27 October 2000) and there is a considerable time before the proceedings will be disposed of finally (perhaps December 2006 at the earliest;
(iv) The proceedings are to be the subject of directions that render them, in a sense, the subject of a new beginning; and
(v) the Applicants will be unable to re-argue in the second part of the matter the issues determined in the first part of the matter (compare the factual circumstances in UnitedGlobalCom at [5]-[6] (ability to re-agitate jurisdictional objections at final hearing) and in Bowman v Ricegrowers' Cooperative Limited (No 2) [2004] NSWIRComm 158 (" Bowman ") at [17]-[18] (ability to re-agitate jurisdiction objections at final hearing)).
(d) Were the Court to decline to address the question of costs at this point and to decline to order that costs be payable forthwith, the question of costs of the first part of the matter would be deferred until the conclusion of the second part of the matter which, on current estimates in terms of preparation, Court availability and resources, hearing and reservation of the decision, is likely to be no earlier than December 2006. As a consequence, the Applicants - despite their success in the proceedings - would be:
(i) unable to recover a significant sum of money from the Respondents in respect of costs for a considerable period of time;
(ii) unable to use such money for that considerable period of time (in addition to the period of time already which the Applicants have been out of the use of such money);
(iii) unable to recover interest on such money, despite being out of the use of such money;
(iv) unable to use such money in the development of their new business following the termination of the Overall Arrangement.
(e) In deciding whether to depart from the general rule that the costs of an interlocutory application are deemed to be costs of the cause and to "otherwise order" that the costs be payable forthwith, the Court should be guided by the "demands of justice" (see Thunderdome Racetiming and Scoring Pty Limited v Dorian Industries Pty Limited (1992) 36 FCR 297 at 312; Horrobin at p9). Although the Court did not make an order as to costs in Interlocutory Judgments No 6, No 7, No 12, No 13 and No 14, the Court should otherwise order that the costs associated with those steps be "payable forthwith".
(f) Additionally, and although the Court " reserved " the costs of the applications in Judgments No 11 and No 15, the Court should otherwise order that the costs associated with the determination of issues in those decisions be "payable forthwith".
