There is no issue that the Court has power to make the order sought by the defendants.
18 Under the common law, courts have been reluctant to order separate hearings on liability unless there is a clear line of demarcation between that issue and damages. A clear example of that reluctance can be seen in Tepko Pty Limited & Ors v Water Board (2001) 206 CLR 1 at [168] - [170] where Kirby and Callinan JJ said:
"[168] 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. "
19 As the defendants have pointed out, since those observations in Tepko, the Civil Procedure Act 2005 has come into force in New South Wales. Sections 56 - 62 of the Act make it clear that considerations of justice have to be tempered by the objectives of case management and the need for proportionality of costs.
20 This change in emphasis was succinctly summarised by Brereton J in Integral Home Loans Pty Limited & Anor v Interstar Wholesale Finance Pty Limited & Anor [2006] NSWSC 1464:
"[6] While much has been said against the resolution of separate questions in Courts of high authority, nonetheless, since the (NSW) Civil Procedure Act 2005, it is my view that the Court should take a more interventionist role in identifying and separating important issues which can resolve significant parts of the litigation expeditiously."
21 His Honour's comments have been adopted and applied in a number of other first instance decisions: Commonwealth Bank of Australia v Clune & Anor [2008] NSWSC 1125 per Johnson J; Barbara O'Sullivan v Challenger Managed Investments Limited [2008] NSWSC 602 per Einstein J; and Vero Insurance Limited v Tran [2008] NSWSC 166 per Hamilton J.
22 The plaintiff's evidence on liability has been conveniently collected in a folder of documents entitled "Plaintiff's Liability Documents". I have had the opportunity of examining those documents. It is clear from them that with the addition of the reports from Professor Starmer, the plaintiff's case on liability is complete. What those documents also reveal is that the plaintiff's case on causation is going to be a difficult one to make out. This is because of the difficulty experienced by the medical profession in diagnosing the plaintiff's condition. That, however, has been the situation ever since the plaintiff's first admission to hospital. There are no indications that it is going to change.
23 What that folder reveals is that apart from the question of diagnosis (which obviously affects quantum as well as liability), there is a clear demarcation between the evidence to be called by the plaintiff on the issue of liability and that relating to quantum. Contrary to the submissions by the plaintiff there was almost no overlap in the evidence to be called on those two issues.
24 That folder also makes clear that apart from diagnosis, all of the factual evidence relating to liability relates to what happened in July 1998. Although statements were taken at the time from students and teachers, I accept that after almost eleven years the recollections of key witnesses must inevitably be adversely affected. Further delay in the hearing of that issue will adversely affect the likelihood of a fair trial taking place. This is particularly so when some of the witnesses were children of twelve at the time.
25 Given the effluxion of time which has already occurred, there is now some urgency in having the issue of liability determined. If quantum were to be heard with liability, further delay would occur as the plaintiff's legal advisers have frankly conceded. That delay is likely to be substantial since there is no indication of when the plaintiff's case on damages will be ready.
26 There is also considerable force in the defendants' submission that a liability hearing would be considerably shorter than a hearing involving both issues. If the defendants were successful on liability, the costs incurred by both sides would be significantly less. On the other hand, if the plaintiff were to be successful on liability there is a strong likelihood, given the rather tragic circumstances of this case, that the defendants would adopt a pragmatic approach and seek to settle the quantum issue.
27 I have concluded that the "just, quick and cheap resolution" of this matter will be significantly facilitated if liability is heard separately to damages. When referring to liability and the order which I propose to make, I intend the word to encapsulate the questions of duty of care, breach of duty and causation, leaving only the question of loss and damage to be determined in a later hearing if necessary.
28 The orders which I make are as follows:
