14 Prior to the hearing of the current application, the plaintiff indicated that it proposed to seek leave to file a further amended statement of claim. A final draft of that claim was subsequently provided to me. Essentially, the amendments raise a further claim to the effect that a dispute has arisen between the parties concerning the proportion in which shared costs should be paid, that dispute should be referred for expert determination in accordance with cl 16 and there should be implied in the SMS terms requiring the parties to give effect to any determination reached by the expert.
15 The defendant's application is that the issues that I have identified as a, b, c and d should be determined separately. In support of that application, Mr Jackman says that, if the plaintiff is successful in relation to those issues, the remaining issues will not arise. On the other hand, if the defendant is successful, the parties have agreed in the SMS to refer the remaining issues to expert determination in accordance with cl 16.
16 There is not a serious dispute between the parties concerning the principles applicable to the question whether the court should order separate determination of one or more issues in a case. Mr Jackman points to some recent authority - such as Integral Home Loans Pty Ltd v Interstar Wholesale Finance Pty Ltd [2006] NSWSC 1464 - where it has been suggested that, since the passing of the Civil Procedure Act 2005, particularly s 56, courts should be more willing to identify separate questions which, if determined, can resolve significant parts of the litigation expeditiously. Nonetheless, the position remains that the determination of separate questions should generally only be ordered if the court is satisfied that doing so will "facilitate the quicker and cheaper resolution of the proceedings": Idoport Pty Ltd v National Australia Bank Ltd [2000] NSWSC 1215 at [7(6)] per Einstein J. In considering that question, the court needs to bear in mind that, while superficially it may appear attractive to order separate questions, experience often shows that that is not the case because, for example, of the complications that can arise in relation to appeals or to overlapping factual issues or to questions of credit, if the same witnesses have to give evidence in relation to questions that are separated and those that are not: see Tepko Pty Ltd v Water Board (2001) 206 CLR 1 at 55 per Kirby and Callinan JJ; Idoport Pty Ltd v National Australia Bank Ltd [2000] NSWSC 1215 at [7(6)] per Einstein J.
17 There are two features about this case which, in my opinion, are particularly relevant to the issue whether the court should make an order for a hearing of separate questions in this case. The first is that the parties have agreed in the SMS that certain questions should be determined in accordance with the dispute resolution procedure set out in cl 16 and that neither party is entitled to commence proceedings in relation to those issues until they have been determined in accordance with that clause. The court starts with the proposition that the parties should be held to their agreement: Strategic Publishing Group Pty Limited v John Fairfax Publications Pty Limited [2003] NSWSC 1134; Ipoh v TPS Property No 2 [2004] NSWSC 289. That is particularly so where, as here, the issues in question turn on matters of expertise - such as the value of different parts of the relevant buildings for the purposes of determining how the insurance premium should be divided between Lots 1 and 2. In my opinion, there is no reason why the parties should not be held to their agreement in this case, at least in so far as that agreement relates to the determination of matters such as value.
18 The second feature of this case is that some of the issues raised by the plaintiff concern the scope and application of cl 16. In particular, one question is whether a deadlock between the parties concerning an amendment to the SMS to alter the proportions in which costs are shared is a dispute to which cl 16 can apply. Another related question is whether the expert can make a determination that is binding on the parties in relation to the proportion in which costs are to be shared notwithstanding cl 21.1. There is a question whether cl 16 applies to a determination of this issue. Even if it does, there seems little point in requiring the parties to submit that issue to determination by an expert in circumstances where the defendant has already indicated that it does not regard itself as bound by an expert's determination of that issue. Moreover, it seems sensible if all issues concerning the construction of cl 16 were dealt with together.
19 It follows from these two points that some part of the proceedings ought to be stayed - that is, that part which is properly the subject of an expert determination under cl 16. On the other hand, it seems to me that there are issues concerning the scope and application of cl 16 which ought to be determined by the court before any expert determination. If those issues are determined adversely to the plaintiff, that will obviate the need for an expert determination of those issues at all. If they are determined favourably to the plaintiff, that will provide a proper context in which the expert determination is to occur and, in doing so, is likely to facilitate a quick determination by the expert. There is no reason why those issues should not be determined at the same time as the issues raised by paragraphs 1 to 15 of the amended statement of claim. Similarly, I cannot see any reason why the court should not determine at that time other legal issues raised by the amended statement of claim - such as whether the court has power to amend the SMS pursuant to s 28U of the SS Act. Those issues are not likely to involve a substantial amount of court time and, it seems to me, there would be efficiencies in having the court determine all issues concerning the construction of the SMS at the same time.
20 There was some discussion at the hearing of this application about the form of any separate questions. It may well be easier in this case to identify the issues that should not be determined by the court rather than those that should. One possibility, for example, is to make an order that all questions raised by the proposed further amended statement of claim other than questions concerning what adjustment, if any, should be made to the proportion in which Shared Costs (as defined in the SMS) are payable and the amount of Shared Costs that are payable by the parties be determined separately. However, I think that it is appropriate to invite the parties to bring in short minutes of order that are consistent with the conclusions that I have reached. If the parties can agree, I will make those orders in chambers. If not, the parties should contact my associate to fix a time for the issue to be dealt with.
21 I think that the appropriate order in relation to costs is to reserve the question of costs. Again, however, if either party contends that some other order should be made, the parties may approach my associate for a time to make an application in that respect.
