Client legal privilege under the Evidence Act
22 The present case is not governed by common law principles of legal professional privilege but rather is governed by the Evidence Act (see s 4(1) of that Act).
23 The Evidence Act in Pt 3.10 Div 1 ss 117-126 deals with client legal privilege. It relevantly provides:
…
118 Legal advice
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 made between the client and a lawyer; or
(b) a confidential communication made between 2 or more lawyers acting for the client; or
(c) the contents of a confidential document (whether delivered or not) prepared by the client, lawyer or another person;
for the dominant purpose of the lawyer, or one or more of the lawyers, providing legal advice to the client.
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.

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) The reference in paragraph (3)(a) to a knowing and voluntary disclosure does not include a reference to a disclosure by a person who was, at the time of the disclosure, an employee or agent of the client or party or of a lawyer of the client or party unless the employee or agent was authorised by the client, party or lawyer to make the disclosure.
(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:
(i) in the course of making a confidential communication or preparing a confidential document; or
(ii) as a result of duress or deception; or
(iii) under compulsion of law; or
(iv) 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 part of the law, under which the body is established or the office is held; or
(b) of 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
(c) of a disclosure to a person with whom the client or party had, at the time of the disclosure, a common interest relating to the proceeding or an anticipated or pending proceeding in an Australian court or a foreign court.
(6) This Division does not prevent the adducing of evidence of a document that a witness has used to try to revive the witness's memory about a fact or opinion or has used as mentioned in section 32 (Attempts to revive memory in court) or 33 (Evidence given by police officers).
24 Section 133 provides:
If a question arises under this Part in relation to a document, the court may order that the document be produced to it and may inspect the document for the purpose of determining the question.
25 In New Cap Reinsurance Corporation Ltd (in liq) v Renaissance Reinsurance Ltd [2007] NSWSC 258 ("New Cap"), White J in the Supreme Court of New South Wales (sitting in the Corporations List) considered the relevant provisions of the Evidence Act in a defendant's application to inspect documents for which the plaintiffs claimed privilege in their list of discovered documents. The documents comprised draft expert reports, requests for instructions from solicitors, records of instructions from solicitors in relation to the preparation of the report and notes and working papers in relation to the report.
26 The plaintiffs contended that the documents in question were not uncommunicated drafts of the report (to which client legal professional privilege did not attach) but rather, privileged communications which had passed between the expert and the plaintiffs' solicitors, for the purpose of providing the plaintiff with professional legal services in connection with the proceeding. Some items were communications between the expert (or members of his firm) and the solicitors, attaching drafts and inviting review.
27 The defendant in New Cap contended that the draft reports were not privileged, or alternatively that privilege had been waived by the plaintiffs' disclosure of the final report for the express purpose of using it as evidence for them in the litigation.
28 White J observed that the application of common law legal professional privilege was limited, as it did not attach to an expert's own documents not communicated to the client (or the client's lawyer) and which do not reveal communications between the expert and client or the client's lawyer (at [18]). The limitation sprang from common law legal professional privilege's concern with communications, rather than documents per se.
29 White J recognised that client legal privilege under the Evidence Act was not subject to the same limitation. Rather, s 119 of the Evidence Act extended to both confidential communications between a client's lawyer and the contents of confidential documents (whether delivered or not) that were prepared for the dominant stated purpose (that is, of the client being provided with professional legal services relating to a proceeding, whether before the Court or anticipated, to which the client is, may, was or might have been a party) (at [20]).
30 White J held that the draft expert reports in the case before him were the subject of client legal privilege, as it could be inferred that they were confidential and produced for the dominant purpose of being communicated to the client's lawyer for the purposes of the litigation (at [22]).
31 His Honour considered that any draft reports prepared and kept by the expert, and any working notes prepared by the expert or his staff, would be privileged under s 119 if they were prepared for the dominant purpose of submitting a draft report for advice or comment by the plaintiff's lawyers (at [29]-[30]). If, however, they were brought into existence for the dominant purpose of the expert forming his own opinions to be expressed in the final report, it was arguable that they were not privileged or made for the dominant purpose of providing the plaintiffs with professional legal services relating to the proceedings (at [30]).
32 White J discussed (at [31]) the meaning of "professional legal services" and appeared to accept the view in Odgers, Uniform Evidence Law, 7th ed, (2006) Sydney, Lawbook Co at paragraph 1.3.10720 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.
33 White J noted that cases such as ASIC v Southcorp were decided on the principles of common law, which were limited to communications rather than documents per se, whereas s 119(b) of the Evidence Act extended privileged to confidential documents, whether communicated or not (at [33]-[34]).
34 His Honour said that the relevant question under s 119(b) was identifying the dominant purpose for which the documents were brought into existence.
35 While White J acknowledged that the issue may not be easy to determine, he considered it probable that where an expert retained by lawyers prepares a draft report, one purpose will be to set out the evidence which the expert intends to give and another purpose will be to enable the draft to be considered and commented on by the lawyers (at [35]). Only if the latter purpose were the dominant purpose would the draft would be privileged (at [35]).
36 In the case before him, White J concluded that the draft reports were privileged because they were copies of the draft report brought into existence for the [dominant] purpose of comment (at [37]). The earlier instructions were privileged as they were brought into existence for the dominant purpose of the client being provided with professional legal services in connection with the proceeding [at [37]]. Whether the same documents retained by the expert were produced for the same dominant purpose would be a different question, which might depend on the expert's oath.
37 White J rejected the defendant's contention (which was based on Lindgren J's observations in ASIC v Southcorp) that the plaintiff had impliedly waived privilege in all the communications between solicitors and the expert, earlier letters of instruction and drafts (at [43]). His Honour noted that ASIC v Southcorp concerned common law legal professional privilege (at [41]).
38 White J discussed loss of privilege under s 122 of the Evidence Act 1995 (NSW) (which was not as yet amended to include sub-sections (2) and (3) in their current form). Section 122(1) provided:
This Division does not prevent the adducing of evidence given with the consent of the client or party concerned.
39 White J stated that consent in that context included imputed consent, as where at common law a party may be taken to have waived privilege, even if there was no subjective intention to do so (at [44]).
40 His Honour referred to the High Court's discussion in Mann v Carnell of inconsistency between, on the one hand, the conduct of the client and, on the other hand, the maintenance of confidentiality, which affected an express or implied waiver (at [44]).
41 Applying the reasoning in Mann v Carnell (which, as it did not recognise an overriding principle of fairness operating at large, to some extent qualified Lindgren J's statements in ASIC v Southcorp), White J concluded that privilege in materials provided to an expert would not be lost merely because an expert is called or his or her report is served (at [54]). Waiver would require, at least, reference to the contents of a document and reliance on it (at [53]).
42 His Honour referred (at [46]) to Dingwall v Commonwealth of Australia (1992) 39 FCR 521 where Foster J (at 524) stated that Attorney-General (NT) v Maurice (1980) 161 CLR 475 ("Maurice") did not go so far as to support waiver of privilege in materials merely because they were sent to a potential witness so that they could provide an expert report. Rather, Maurice required, for waiver, "an indication that documents were used in the preparation of the evidentiary document in a way that could be said to influence the content of that document".
43 White J did not recognise any universal entitlement in the opposite party to test whether the relevant privileged documents influenced the content of the expert's report (at [48]).
44 In New Cap, the expert specified material on which he relied, which did not include draft reports or earlier letters of instruction. White J inspected the documents in dispute in an attempt to discern whether they may have relevantly influenced the content of the report. His Honour acknowledged that the usefulness of such an exercise was limited (at [51]). The expert could, for example, have genuinely changed his or her opinion, so that the mere fact of a difference between the final report and the draft would not establish that the latter influenced the former in the relevant sense (at [52], see Linter Group Ltd v PriceWaterhouse [1999] VSC 245 at [16] per Harper J).
45 Further, White J recognised that there are many different senses in which the legal advisers might be said to influence the content of the report (eg, advice in relation to admissible form) which would not be inconsistent with maintaining the privilege because it would be unfair to rely on the final report without disclosing the earlier materials (at [53]).
46 In Cadbury Schweppes Pty Ltd v Darrell Lea Chocolate Shops Pty Ltd (No 7) [2008] FCA 323, Heerey J of the Federal Court, in reliance on New Cap, Natuna Pty Ltd v Cook [2006] NSWSC 1367 and ML Ubase Holdings Co Ltd v Trigem Computer Inc [2007] NSWSC 859, concluded (at [3]):
There is a clear line of authority which establishes that draft documents and other communications of a like nature with an expert witness proposed to be called in litigation are privileged under s 119(b) whatever may have been the position at common law …
47 More recently, in Traderight v Bank of Queensland Ltd (No 14) [2013] NSWSC 211, ("Traderight") Ball J refused an application by the respondent bank for access to documents relating to the preparation of an expert's report prepared on instructions from the solicitors for the plaintiffs, over which the plaintiffs claimed privilege. Broadly, the documents sought by the respondent bank included draft reports prepared by the expert containing comments, requests or advice by the legal advisers; draft reports created for the dominant purpose of providing them to the legal advisers for consideration or comment; and documents recording the communications between the expert and the legal advisers in relation to the draft reports or their preparation, for the dominant purpose of the legal advisers considering or providing comment or advice (at [3]).
48 It was not disputed that the above documents were, on their face, subject to client legal professional privilege under s 119 of the Evidence Act 1995 (NSW) (which was relevantly in the same terms as the Evidence Act 1995 (Cth)).
49 The bank relied on the exceptions to legal professional privilege under s 122(2) of the Evidence Act 1995 (NSW).
50 Ball J noted (at [10]) that the amendment to s 122(2) (in force from 1 January 2009) was made pursuant to the recommendation of a joint report of the Australian Law Reform Commission, New South Wales Law Reform Commission and Victorian Law Reform Commission (Uniform Evidence Law, ALRC Report 102, NSWLR Report 112 and VLRC Final Report (February 2006) ("Joint Report"). The Joint Report followed the High Court's decision Mann v Carnell (1999) 201 CLR 1, where Gleeson CJ and Gaudron, Gummow and Callinan JJ (at [29]) stated that the waiver of legal professional privilege depended on 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. The Joint Report recommended that s 122 be amended to align it more closely with the common law as set out in Mann v Carnell. Ball J stated at [12]:
It is clear from these paragraphs that s 122(2) in its current form is intended largely to adopt the test for waiver at common law as explained by the High Court in Mann v Carnell and that s 122(3) is intended to give some examples of the application of that test.
51 His Honour recognised that ASIC v Southcorp provided context for cases such as New Cap. He further stated at [21]:
It is clear, however, that the approach taken by White J to s 122(1) is now applicable to s 122(2). White J proceeded on the basis that s 122(1) incorporated principles of common law waiver. As I have explained, those principles are now encapsulated in s 122(2). The narrow approach taken by Brereton J to s 122 no longer applies to the section as amended. Although Mr Cotman SC, who appeared for the OMB Parties, took me to a number of other cases, there was no real dispute between the parties that the principles as stated by White J were the principles to be applied in this case.
52 Ball J concluded that in the case before him, privilege in the communications between the expert and the legal advisers was not lost as there was nothing to indicate that the expert's conclusions were not her own or were based on material which the report did not disclose (at [23]).
