Legal Principles
27The principles relating to whether or not separate questions should be ordered are well known. They may be shortly encapsulated.
28In exercise the discretion which exists in r 28.2 of the Uniform Civil Procedure Rules, to make an order for the separate hearing and determination of a part of a matter, it is essential that the Court gives effect to the provisions of s 56 of the Civil Procedure Act 2005. By s 56(2), the Court is obliged to seek to give effect to the overriding purpose of the Civil Procedure Act and Rules of Court when exercising any power given to it by the Act or Rules of Court.
29Section 56(1) provides that:
"The overriding purpose of this Act and of rules of court, in their application to a civil dispute or civil proceedings, is to facilitate the just, quick and cheap resolution of the real issues in the dispute or proceedings."
30The commencing point for the consideration of an order such as the one being sought is that it is ordinarily appropriate that all issues in proceedings should be disposed of at the one time: Commonwealth Bank of Australia v Clune [2008] NSWSC 1125 at [5] per Johnson J.
31In Perre v Apand Pty Ltd (1999) 198 CLR 180 at 332 [436], Callinan J said:
"Care does need to be taken in deciding whether to conduct separate trials of different issues. It sometimes happens that they may turn out to be productive of the disadvantages of delay, extra expense, appeals and uncertainty of outcome which they are intended to avoid. In tort cases in which damage is the gist of the action, it will be generally be undesirable to accede to requests for them, or to order them, unless all parties accept that compensable damage has been sustained by the plaintiffs or applicants as the case may be".
32In Tepko Pty Ltd v Water Board (2001) 206 CLR 1 at 55, Kirby and Callinan JJ said at [168]-[170]:
"168. The appeal should be allowed. However, we should not leave this case without making four comments. Both Mason P and Fitzgerald JA were critical of the course of limiting the issues to be tried that the primary judge adopted. In Perre v Apand Pty Ltd attention was drawn to difficulties that can be caused when that course is adopted. In light of the experience in this case, what was there said should be restated with emphasis. The attractions of trials of issues rather than of cases in their totality, are often more chimerical than real. Common experience demonstrates that savings in time and expense are often illusory, particularly when the parties have, as here, had the necessity of making full preparation and the factual matters relevant to one issue are relevant to others, and they all overlap.
169. The second and related comment is this. A party, whose whole case is knocked out on a trial of a preliminary or single issue, may suspect, however unjustifiably, that an abbreviated course was adopted and a decision reached in the court's, rather than the parties', interests.
170. Thirdly, there is an additional potential for further appeals to which the course of the trial on separate issues may give rise. Indeed, that could occur here were this appeal to be allowed and a retrial had in which the remaining issues of causation and damages were decided. Single-issue trials should, in our opinion, only be embarked upon when their utility, economy, and fairness to the parties are beyond question."
33Although these remarks were made prior to the introduction of the Civil Procedure Act, and whilst there may be room for a different view as to whether the Court should take a more interventionist role in particular cases, in identifying and separating issues which can resolve significant parts of litigation expeditiously: see Integral Home Loans Pty Ltd v Interstar Wholesale Finance Pty Ltd [2006] NSWSC 1464 at [6], I am satisfied that it remains the case that determination of separate questions is an unusual, perhaps exceptional, course which is only to be taken when the benefit can be seen to clearly outweigh the disadvantages of the kind discussed by Kirby and Callinan JJ in Tepko.
34Einstein J in Idoport Pty Ltd v National Australia Bank Ltd [2000] NSWSC 1215 has helpfully summarised the principles to be applied by a Court in considering whether to order the determination of separate questions. I will not set out the entirety of those principles. I derive from his Honour's judgment, with which I express respectfully, my agreement, the following principles of relevance in this case:
(a) it is for the party seeking the order to show to the Court that it is desirable for the determination of the separate question to occur: Idoport at [7(3)];
(b) the determination of a separate question may be appropriate where the resolution of the separate issue carries with it a strong prospect that the parties will be able to resolve their dispute themselves: Idoport at [7(4)(b)];
(c) the determination of a separate question will be unlikely to be appropriate where there is a commonality of witnesses and issues of credit as between the separate issue and the other issues in the case which will, or may, necessitate a ruling on the credit of one or more witnesses: Idoport at [7(5)(b)]; and
(d) a determination of a separate question is unlikely to be appropriate unless it is possible to clearly see that the determination will facilitate the just, quick and cheap resolution of the proceedings or the central issues in the proceedings: Idoport at [7(6)];
35Giles CJ in Comm Div (as his Honour then was) said in Tallglen Pty Ltd v Pay TV Holdings Pty Ltd (1996) 22 ACSR 130 at 141-142:
"Part 31 r 2 of the rules empowers the court to make orders for the decision of any question separately from any other question, whether before, at or after any trial or further trial in the proceedings, and for the statement of a case and the question for decision. In the ordinary course all issues in proceedings should be decided at the one time, but separate decision of a question may be appropriate where, for example, the decision of the question is critical to the outcome of the proceedings and (at least if decided in one way) will bring the proceedings to an end. In particular circumstances the separate decision of a question may be appropriate even if it will not bring the proceedings to an end, such as where there is a strong prospect that the parties will agree upon the result when the core of their dispute is decided or where the decision will obviate unnecessary and expensive hearing of other questions, but such occasions must be carefully controlled lest fragmentation of the proceedings (particularly when the exercise of rights of appeal is borne in mind) brings delay, expense and hardship greater than that which the making of an order was intended to avoid. It is often the case that the need to make findings of fact for a decision of the separate question, especially findings which may involve issues of credit, tells strongly against the making of an order because related facts, and renewed issues of credit, will or may arise at a later stage in the proceedings. Experience teaches that it should be able to be seen with clarity that decision of a separate question will be beneficial in the conduct of the proceedings and the resolution of the parties' dispute."
36Although the judgment was dealing specifically with r 31.2 of the Supreme Court Rules, the principles that are articulated, and the approach taken, are directly applicable to these proceedings.
