Discussion
11The plaintiff's resistance to production of Dr Walshe's report is based on two propositions. The first is that any report referring to it was provided to the defendant under compulsion of law so that no waiver of any privilege otherwise attaching to it has occurred in the circumstances: see Sevic v Roarty (1998) 44 NSWLR 287. The second is that the plaintiff has not yet sought to tender any of the reports of Dr Grantham or Mr Plaister that contain a reference to Dr Walshe's report, so that the time has not yet arrived when the plaintiff can be said to have waived any privilege at all. The second proposition seems to me to be in truth not a separate ground at all but rather a function of the reasoning process adopted in some of the authorities upon which the plaintiff relies in support of the first.
"Under compulsion of law"
12Section 119 of the Evidence Act 1995 is relevant and provides as follows:
"119 Litigation
Evidence is not to be adduced if, on objection by a client, the court finds that adducing the evidence would result in disclosure of:
(a) a confidential communication between the client and another person, or between a lawyer acting for the client and another person, that was made, or
(b) the contents of a confidential document (whether delivered or not) that was prepared,
for the dominant purpose of the client being provided with professional legal services relating to an Australian or overseas proceeding (including the proceeding before the court), or an anticipated or pending Australian or overseas proceeding, in which the client is or may be, or was or might have been, a party."
13It is accepted for the purposes of my deliberations that Dr Walshe's report is a document that falls within the terms of that section.
14Section 122 is the source of the expression "under compulsion of law". It is in the following relevant terms:
"122 Loss of client legal privilege: consent and related matters
(1) This Division does not prevent the adducing of evidence given with the consent of the client or party concerned.
(2) Subject to subsection (5), this Division does not prevent the adducing of evidence if the client or party concerned has acted in a way that is inconsistent with the client or party objecting to the adducing of the evidence because it would result in a disclosure of a kind referred to in section 118, 119 or 120.
(3) Without limiting subsection (2), a client or party is taken to have so acted if:
(a) the client or party knowingly and voluntarily disclosed the substance of the evidence to another person, or
(b) the substance of the evidence has been disclosed with the express or implied consent of the client or party.
(4) ...
(5) A client or party is not taken to have acted in a manner inconsistent with the client or party objecting to the adducing of the evidence merely because:
(a) the substance of the evidence has been disclosed:
...
(iii) under compulsion of law..."
15In Akins and Others v Abigroup Ltd [1998] NSWCA 8; (1998) 43 NSWLR 539, the Court of Appeal determined that the disclosure of an otherwise privileged witness statement in accordance with an order of a court, even if the order is termed a procedural direction, is a disclosure under "compulsion of law" within the meaning of s 122(2)(c), so that client legal privilege is not thereby waived. Mason P said this at 550-551:
"Senior counsel for Deloittes submits that the disclosure of the statements was not under compulsion of law because the usual order made pursuant to Practice Note 39 left it open to the parties in the directors' proceedings to choose whether or not they wished to disclose the information contained in the disclosed statements or the statements themselves. It was further submitted that the usual order merely brought forward the time at which the parties to the directors' proceedings would have waived any privilege touching the contents of the statements when they decided to tender those statements or called the makers of them as witnesses (cf Comfort Hotels Ltd v Wembley Stadium Ltd [1988] 1 WLR 872 at 877-8).
I would reject these submissions. In my view any disclosure by delivery of copies of the statements was "under compulsion of law" within s 122(2)(c)."
16Sevic v Roarty was decided later the same year. Sheller JA expressed his conclusion at 300 as follows:
"The application of the decisions in Akins v Abigroup Ltd and Adelaide Steamship Co Ltd & Australian Securities Commission v Spalvins to this appeal means that the provisions of the Act determine whether the respondent, despite the filing of a report from Dr Tinning which referred to other documents, was entitled to resist the appellant's call for the production of those documents on the basis that legal professional privilege in them had been waived. Under the provisions of the Act, legal professional privilege had not been waived by the respondent."
17Powell JA expressed his views at 301:
"Whatever may earlier have been the position...the position would seem now to be that waiver is not to be implied or imputed where the document the delivery of which is relied upon to found the implication, or to support the imputation, of waiver, was delivered - whether to the other party to the litigation or to a third party - pursuant to an order of a court or otherwise under compulsion of law unless the document be later tendered in evidence on the hearing of the proceedings in which the parties are involved, or otherwise used in such a way on the hearing of those proceedings as would make it unfair to the other party not to treat the privilege as having been waived."
18His Honour concluded his analysis at 308 in these terms:
"In the present case, Dr Tinning's report was filed, and a copy served, in pursuance of a direction given by the Court. As is clear, that report has not yet been, and may never be, tendered in evidence, nor has it been used in any way which would, in my view, make it unfair for the appellant, at this stage of the proceedings, to be denied access to the documents to which it refers. What course should be taken if, and when, it is sought to tender Dr Tinning's report in evidence, or to have Dr Tinning give evidence to the effect of that contained in his report, is not a matter which this Court is called upon to determine and can only properly be determined in the circumstances existing at the time."
19Recently in Gillies v Downer EDI Ltd [2010] NSWSC 1323, Garling J expressed some doubt at [46] about the continuing significance of these decisions:
"[46] That line of authority should be treated with some caution for the following reasons:
(a) It has recently been subject to criticism from the Full Court of the Federal Court of Australia in Liberty Funding Pty Ltd v Phoenix Capital Ltd (2005) 218 ALR 283 at [24]-[27] per Branson, Sundberg & Allsop JJ; and by the Court of Appeal in Dubbo City Council v Barrett [2003] NSWCA 267 at [20] per Young CJ in Eq.
(b) Sevic v Roarty applied an earlier version of s 122, the terms of which are different from the current section. The relevant sub-paragraph at that time provided:
'(2) Subject to subsection (5), this Division does not prevent the adducing of evidence if a client or party has knowingly and voluntarily disclosed to another person the substance of the evidence and the disclosure was not made:
...
(c) under compulsion of law...'
(c) Section 131A, which was introduced by the Evidence Amendment Act 2007 and came into force on 1 January 2009, and thus did not exist at the time of the decisions of Akins and Sevic, effectively requires the Court to determine a pre-trial claim for privilege as though the claim was made in the course of adducing evidence at trial. It seems at least arguable that, for the purposes of determining whether privilege is lost, there should no longer be a distinction between an expert report served pursuant to case management orders prior to the commencement of a trial and the calling of witnesses, and an expert report relied upon during the trial once a witness has been called.
(d) The consequences of the decision in Sevic were most impractical from the perspective of the efficient running of the litigation, including the proper and efficient preparation for trial and the taking of evidence at the trial. Those consequences do not fit comfortably with modern case-management practices, and in particular the '... just, quick and cheap ...' principle to which litigation is subject in this Court."
20White J also considered the question in New Cap Reinsurance Corporation Ltd (in liq) v Renaissance Reinsurance Ltd [2007] NSWSC 258 at [53] as follows:
"[53] The question is not merely whether it could be said that the privileged materials were used in such a way that they could be said to influence the content of the report, but whether it could be said that they influenced the content of the report in such a way that the use or service of the report would be inconsistent with maintaining the privilege in those materials, such as, where it would be unfair for the party to rely on the report without disclosure of those materials. Where an expert's report is submitted to a party's legal advisers so as to be put into a form which will ensure that it is admissible, it can be said that the privileged communications between the expert and the lawyers have influenced the content of the report, in the sense of its form, although not in the sense of the formulation of the substantive opinions expressed by the expert. Likewise, privileged communications between an expert and the party's lawyers whereby material information is provided to the expert in the form of assumptions or documents may well influence the content of the report. However, an expert's report is required to state what material and assumptions are relied on. Use of a final report, which refers to such materials and assumptions, is not inconsistent with maintaining confidentiality in the communications which produced the final product."
21Counsel for the defendant embraced the significance of the rules relating to the preparation of experts' reports in aid of his submission that the privilege in Dr Walshe's report had been lost. UCPR 31.27(1) provides as follows:
"31.27 Experts' reports
(1) An expert's report must (in the body of the report or in an annexure to it) include the following:
(a) the expert's qualifications as an expert on the issue the subject of the report,
(b) the facts, and assumptions of fact, on which the opinions in the report are based (a letter of instructions may be annexed),
(c) the expert's reasons for each opinion expressed,
(d) if applicable, that a particular issue falls outside the expert's field of expertise,
(e) any literature or other materials utilised in support of the opinions,
(f) any examinations, tests or other investigations on which the expert has relied, including details of the qualifications of the person who carried them out,
(g) in the case of a report that is lengthy or complex, a brief summary of the report (to be located at the beginning of the report)."
22The defendant argued that it was not enough for the report simply to refer to the materials utilised in support of the opinion but that it must provide or furnish copies of any such materials. This is said to follow from the phrase "an expert's report must ... include any literature or other materials utilised in support of the opinions". Neither party was able to take me to any relevant authority dealing with the proper interpretation of this rule.
23The defendant also embraced the proposition adverted to by Garling J in Gillies, to the effect that the s 56 Civil Procedure Act 2005 imperative meant that it was potentially inconsistent with the overriding purpose for there to be any delay between the service of a particular report and the determination of whether or not privilege over it or its contents had been waived. In particular it was said to be inimical to the just, quick and cheap resolution of proceedings for there to be any possibility that a trial, for which all parties may have prepared at great length and considerable expense, might be derailed by an argument, or the outcome of an argument, about such an issue. The defendant contended that the combination of s 56 and UCPR 31.27 supported the notion that (in this case) the plaintiff's as yet unknown decision at the trial about whether or not to tender any expert's report that refers to Dr Walshe's report should not be the event triggering the earliest consideration of the issue. In lay terms, the earlier the issue is decided, the better for all concerned.
