and his Honour referred generally to Baker v Campbell.
None of the parties submitted that the Evidence Act provisions did not cover the second limb of Grant v Downs and I proceed on the basis that it does. "
28 A lawyer will provide professional legal services in relation to a witness' statement of evidence where the lawyer is asked to advise on what the statement should contain and settle the form of the statement. The deployment of the final report by the plaintiff's lawyers through its service on the opposite party and its tender into evidence will also constitute the provision of professional legal services relating to the proceeding.
29 Section 119 directs attention to the dominant purpose for which each confidential communication or confidential document comes into existence. The dominant purpose for which a final expert's report or final witness statement is brought into existence would presumably be for the purpose of being laid before the Court as the witness' evidence. Prima facie, it would not be privileged (Attorney-General (NT) v Maurice at 480). However, draft reports, and notes used in preparing a report, may stand at a different position, particularly where the expert has been retained by the party's solicitors and it is expected that the party's lawyers will advise on the contents of, and settle the form of, the report. There is nothing improper in such a course. It is not inconsistent with the expert's paramount duty being the duty to the Court and not to the client retaining him or her.
30 It will be a question of fact, to which the expert may be required to put his or her oath, as to whether any draft reports prepared and kept by him, and working notes prepared by him or his staff, were brought into existence for the dominant purpose of the plaintiffs being provided with professional legal services. If they were prepared for the dominant purpose of a draft report being submitted for advice or comment by the plaintiffs' lawyers, then they would be privileged under s 119. However, if they were brought into existence for the dominant purpose of the expert forming his or her opinions to be expressed in the final report, then it could be arguable that they were not made for the dominant purpose of the plaintiffs being provided with professional legal services relating to the proceedings.
31 The expression "professional legal services" is not defined. In Odgers, Uniform Evidence Law, 7th ed, (2006) Sydney, Lawbook Co at para 1.3.10720, the learned author says that: "Since providing a client with professional legal services includes representing the client in legal proceedings, it is likely that a document prepared for use in such legal proceedings by the client's lawyer will be privileged." That, of course, does not answer the question whether a document prepared by an expert witness for use by him or her in giving his or her evidence in the proceedings is privileged. It is not, unless it was prepared for the dominant purpose of the client being provided with professional legal services.
32 In Ryder v Frohlich [2005] NSWSC 1342, Barrett J said (at [11] and [12]) quoting in part Thomas J in Interchase:
" [11] …
'I would hold that in general, when an expert is engaged by a solicitor for the purpose of giving evidence in a case, documents generated by the expert and information recorded in one form or another by the expert in the course of forming an opinion are not a proper subject for a claim of legal professional privilege. Privilege may however be claimed in relation to communications between the expert and the solicitor (both ways) when such communication is made for the purpose of confidential use in the litigation. Beyond this there is no sufficient reason why any material relevant to the formation of the expert's opinion should be subject to a claim of legal professional privilege. It is as well to add that an expert or solicitor may not artificially manufacture privilege by, for example, the expert sending in his or her file to the solicitor. Documents of this kind simply are not confidential.'
[12] The point made here is that privilege can only attach to documents which embody communication between the expert and the litigant by whom the expert is retained (or the litigant's lawyer). A draft report prepared by the expert is not, of its nature, such a communication. It may be that the draft report is, in fact, given or sent by the expert to the litigant or the litigant's lawyer, but that does not change its character as something prepared by the expert which is not intended to be a means of communication with the litigant or lawyer. "
33 His Honour's reasoning was heavily influenced by Lindgren J's judgment in Australian Securities and Investments Commission v Southcorp Ltd (2003) 46 ACSR 438 (at [21]), and by Interchase Corporation Ltd v Grosvenor Hill (Queensland) Pty Ltd (No. 1) [1999] 1 Qd R 141. As Biscoe AJ pointed out in Natuna Pty Ltd v Cook [2006] NSWSC 1367 at [8], those cases turned upon principles of common law, and not s 119(b), with the emphasis, at least in more recent cases, on privilege applying to communications, rather than documents per se.
34 Section 119(b) of the Evidence Act extends the privilege to confidential documents, whether communicated or not, provided they were brought into existence with the requisite dominant purpose. The question however is what that purpose is. If an expert prepares a draft report, or notes for the report, with the dominant purpose of a draft report (whether the precise draft then prepared by the expert or an intended later draft) being furnished for comment or advice by the lawyer, then it is privileged. If not, it is not.
35 The issue may not be an easy one to determine. In all probability, an expert witness retained by a lawyer for a party will prepare a draft report with the intention (and purpose) that it will set out the evidence which he or she expects to give, but also with the intention and purpose of its being considered and commented on by the party's lawyers. If the latter purpose is dominant, the document so produced is privileged. If not, it is not privileged.
36 In this way, in the case of claims for privilege over working notes and expert's draft reports not communicated to a client's lawyer, the same practical outcome may be reached in many cases whether the privilege is claimed at common law or under s 119 of the Evidence Act. However, the analysis of the claims must proceed on different paths.
37 It suffices to say that the draft reports which are the subject of the notice of motion are privileged because they were copies of the draft report sent to the plaintiffs' lawyers for the purposes of comment. Whether the same documents in the hands of the expert were produced for the same dominant purpose will be a different question, the resolution of which may depend upon the expert's oath. Instructions in relation to draft reports, or requests for such instructions, are also privileged under s 119(b) as they were brought into existence for the dominant purpose of the client being provided with profesional legal services in connection with the proceedings.
Waiver of Privilege by Service of the Final Report
38 The question of whether privilege in drafts of the reports, earlier letters of instruction, and notes prepared for preparation of the report has been waived by service of the final report depends on whether s 122 of the Evidence Act would allow such evidence to be adduced notwithstanding s 119. Section 122 relevantly provides:
" 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 a client or party has knowingly and voluntarily disclosed to another person the substance of the evidence and the disclosure was not made:
(a) in the course of making a confidential communication or preparing a confidential document, or
(b) as a result of duress or deception, or
(c) under compulsion of law, or
(d) if the client or party is a body established by, or a person holding an office under, an Australian law - to the Minister, or the Minister of the Commonwealth, the State or Territory, administering the law, or the part of the law, under which the body is established or the office is held.
(3) Subsection (2) does not apply to a disclosure by a person who was, at the time, an employee or agent of a client or party or of a lawyer unless the employee or agent was authorised to make the disclosure.
(4) Subject to subsection (5), this Division does not prevent the adducing of evidence if the substance of the evidence has been disclosed with the express or implied consent of the client or party to another person other than:
(a) a lawyer acting for the client or party, or
(b) if the client or party is a body established by, or a person holding an office under, an Australian law - the Minister, or the Minister of the Commonwealth, the State or Territory, administering the law, or the part of the law, under which the body is established or the office is held.
(5) Subsections (2) and (4) do not apply to:
(a) a disclosure by a client to another person if the disclosure concerns a matter in relation to which the same lawyer is providing, or is to provide, professional legal services to both the client and the other person, or
(b) a disclosure to a person with whom the client or party had, at the time of the disclosure, a common interest relating to a proceeding or an anticipated or pending proceeding in an Australian court or a foreign court. "
39 Also relevant is s 126 of the Evidence Act. It provides:
"126 Loss of client legal privilege: related communications and documents
If, because of the application of section 121, 122, 123, 124 or 125, this Division does not prevent the adducing of evidence of a communication or the contents of a document, those sections do not prevent the adducing of evidence of another communication or document if it is reasonably necessary to enable a proper understanding of the communication or document.
Note. Example:
A lawyer advises his client to understate her income for the previous year to evade taxation because of her potential tax liability "as set out in my previous letter to you dated 11 August 1994". In proceedings against the taxpayer for tax evasion, evidence of the contents of the letter dated 11 August 1994 may be admissible (even if that letter would otherwise be privileged) to enable a proper understanding of the second letter."
40 The defendants submitted that by serving the expert's report, the plaintiffs impliedly waived privilege in all of the communications between the plaintiffs' solicitors and the expert, including earlier letters of instruction, drafts of the report submitted to the plaintiffs' solicitors, and communications between the plaintiffs' solicitors or counsel and the expert. The defendants relied upon Australian Securities and Investments Commission v Southcorp Ltd (at [21]). Lindgren J said:
" [21] I will apply the following principles which I did not understand to be in dispute:
(1) Ordinarily the confidential briefing or instructing by a prospective litigant's lawyers of an expert to provide a report of his or her opinion to be used in the anticipated litigation attracts client legal privilege: cf Wheeler v Le Marchant (1881) 17 Ch D 675; Trade Practices Commission v Sterling (1979) 36 FLR 244 at 246; Interchase Corp Ltd (in liq) v Grosvenor Hill (Qld) Pty Ltd (No 1) [1999] 1 Qd R 141 ( Interchase ) at 151 per Pincus JA, at 160 per Thomas J.
(2) Copies of documents, whether the originals are privileged or not, where the copies were made for the purpose of forming part of confidential communications between the client's lawyers and the expert witness, ordinarily attract the privilege: Commissioner of Australian Federal Police v Propend Finance Pty Ltd (1997) 188 CLR 501 ; 141 ALR 545 ; 91 A Crim R 451 ( Propend ); Interchase , per Pincus JA; Spassked Pty Ltd v Cmr of Taxation (No 4) (2002) 50 ATR 70 at [17].
(3) Documents generated unilaterally by the expert witness, such as working notes, field notes, and the witness's own drafts of his or her report, do not attract privilege because they are not in the nature of, and would not expose, communications: cf Interchase at 161-2 per Thomas J.
(4) Ordinarily disclosure of the expert's report for the purpose of reliance on it in the litigation will result in an implied waiver of the privilege in respect of the brief or instructions or documents referred to in (1) and (2) above, at least if the appropriate inference to be drawn is that they were used in a way that could be said to influence the content of the report, because, in these circumstances, it would be unfair for the client to rely on the report without disclosure of the brief, instructions or documents; cf Attorney-General (NT) v Maurice (1986) 161 CLR 475 at 481 ; 69 ALR 31 at 34 per Gibbs CJ, CLR 487-8; ALR 38-9 per Mason and Brennan JJ, CLR 492-3; ALR 42-3 per Deane J, CLR 497-8; ALR 46-7 per Dawson J; Goldberg v Ng (1995) 185 CLR 83 at 98 ; 132 ALR 57 at 66 per Deane, Dawson and Gaudron JJ, CLR 109; ALR 75 per Toohey J; Instant Colour Pty Ltd v Canon Australia Pty Ltd [1995] FCA 870; BC9506842 Australian Competition and Consumer Commission v Lux Pty Ltd [2003] FCA 89; BC200300344 ( ACCC v Lux ) at [46].
(5) Similarly, privilege cannot be maintained in respect of documents used by an expert to form an opinion or write a report, regardless of how the expert came by the documents; Interchase at 148-50 per Pincus JA, at 161 per Thomas J.
(6) It may be difficult to establish at an early stage whether documents which were before an expert witness influenced the content of his or her report, in the absence of any reference to them in the report: cf Dingwall v Commonwealth of Australia (1992) 39 FCR 521; Tirango Nominees Pty Ltd v Dairy Vale Foods Ltd (No 2) (1998) 83 FCR 397 at 400 ; 156 ALR 364 at 366; ACCC v Lux at [46]."
41 Notwithstanding the reference to client legal privilege, Lindgren J was speaking of common law principles of legal professional privilege.
42 It was submitted for the plaintiffs that there could be no waiver of privilege by service of the expert's report because the report was served pursuant to an order requiring its service. The disclosure of the report was therefore not voluntary (Akins v Abigroup Ltd (1998) 43 NSWLR 539; Sevic v Roarty (1998) 44 NSWLR 287; Dubbo City Council v Barrett [2003] NSWCA 267).
43 The consequence of the expert's report having been served under compulsion of law is that s 122(2) does not apply so as to permit the adducing of the report as evidence over the plaintiffs' objection, on the ground that the plaintiffs have knowingly and voluntarily disclosed to another person the substance of that evidence. That is not the present question. The question is not whether privilege in the contents of Mr Smith's final report is being waived because its disclosure was under compulsion of law. Rather, the question is whether privilege in draft reports and prior communications between the plaintiffs' solicitors and the expert, and related documents, has been waived. The service of the final report did not disclose the substance of the prior communications. There is no question of privilege having been waived pursuant to s 122(2).
44 The question is whether privilege has been waived by s 122(1). It is now firmly established that consent under s 122(1) includes a consent which will be imputed to a party on the same principle where, at common law, a party will be taken to have waived privilege, even though he or she did not subjectively intend to do so (Chen & Ors v City Convenience Leasing Pty Ltd & Anor [2005] NSWCA 297 at [29]-[33]). That principle is that:
" It is inconsistency between the conduct of the client and maintenance of the confidentiality which effects a waiver of the privilege … waiver may be express or implied. Disputes as to implied waiver usually arise from the need to decide whether particular conduct is inconsistent with the maintenance of the confidentiality which the privilege is intended to protect. When an affirmative answer is given to such a question, it is sometimes said that waiver is 'imputed by law'. … What brings about the waiver is the inconsistency, which the courts, where necessary informed by considerations of fairness, perceive, between the conduct of the client and maintenance of the confidentiality; not some overriding principle of fairness operating at large ." ( Mann v Carnell (1999) 201 CLR 1 at [28] and [29].
45 The qualification in paragraph 4 of Lindgren J's statement of principles set out in Australian Securities and Investments Commission v Southcorp Ltd is significant. There are many cases in which it has been held that privilege in material provided to an expert is not lost merely because the expert is called, or the expert's report is served. In Bourns Inc v Raychem Corporation [1999] 3 All ER 154, Aldous LJ said (at 166-167):
" Service of a witness statement, whether it be a statement of an expert or a witness to fact, waives privilege in that statement. As stated in the Marubeni Corp case mere reference to a document does not waive privilege in that document: there must at least be reference to the contents and reliance. In the present case there was no reference and no reliance therefore no waiver. "
