Waiver of client legal privilege
24 Client legal privilege in court proceedings is set out in Div 1 of Pt 3.10 of the Evidence Act 1995. Section 118 excludes the adducing of evidence of confidential communications between client and lawyer. It provides:
"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 or a lawyer;
for the dominant purpose of the lawyer, or one or more of the lawyers, providing legal advice to the client."
25 Section 122 of the Evidence Act 1995 provides exceptions to this rule where a party consents to the adducing of the evidence, or the substance of the communication has been disclosed, or the document is used to refresh memory. It is in the following terms:
"(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 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 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.
(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 by police officers)."
26 In Telstra Corporation v Australis Media Holdings (1997) 41 NSWLR 277 McLelland CJ in Eq took the view that while those provisions did not, on their face, apply to ancillary process but were limited to the giving of evidence, they nonetheless applied derivatively to claims to privilege in ancillary process. That approach was adopted by a Full Court of the Federal Court in Adelaide Steamship Co Ltd v Spalvins (1998) 81 FCR 360 and by this Court in Akins v Abigroup Ltd (1998) 43 NSWLR 539.
27 The approach was rejected by the High Court in ESSO Australia Resources Ltd v Commissioner of Taxation (1999) 201 CLR 49. It was said at [23] that as the provisions of the Evidence Act 1995 with respect to client legal privilege did not apply throughout Australia, there was not a consistent pattern of legislative policy to which the common law in Australia could adapt. Thus the common law could not be modified by analogy or derivation to accord with the provisions of the legislation and it was the common law that governed legal professional privilege in ancillary process.
28 That was not the position in New South Wales after 1 October 1999 for the Supreme Court Rules 1970 were amended to apply the Evidence Act 1995 provisions to discovery and inspection of documents under Pt 23 r 1, to answers to interrogatories under Pt 24 r 6 and to calls on subpoenas under Pt 36 r 13. Amendments to the same effect were made to the District Court Rules 1973, Pt 22 r 16 (discovery and inspection of documents), Pt 22A r 6(3)(c) (interrogatories) and Pt 29 r 1 (subpoenas).
29 At common law, a client who would otherwise be entitled to the benefit of legal professional privilege, might waive that privilege and that waiver might be express or implied (Mann v Carnell (1999) 201 CLR 1 at [28]-[29]). If the Evidence Act 1995, s 122(1) was meant to embrace or to restrict this principle, its expression is elliptical in the extreme.
30 In Adelaide Steamship at 370-371, the Court saw no reason for construing consent in s 122(1) of the Evidence Act 1995 as referring only to express consent notwithstanding the contrast with s 122(4) where reference is made to express or implied consent. In Telstra Corporation Ltd v BT Australasia Pty Ltd (1998) 85 FCR 152, a majority of a Full Court of the Federal Court cited this observation and also concluded that the reference to consent in the Evidence Act 1995, s 122(1) included the implied consent of an imputed waiver of privilege. Their Honours said at 164:
"But, unless "consent" has a meaning more extensive than actual, voluntary consent, it is difficult to see what s 122(1) adds to the opening words of s 118. And it may be observed that if s 122(1) of the Act is construed as being concerned only with intended or voluntary consent, Div 1 of Pt 3.10 of the Act will have effected a dramatic change to the pre-existing common law with respect to legal professional privilege."
31 In my view, that interpretation must be correct. Section 9(1) of the Evidence Act 1995 provides that the Act does not affect the operation of a principle or rule of common law or equity in relation to evidence in a proceeding to which the Act applies, except so far as the Act provides otherwise expressly or by necessary intendment. It would take more than the reference to implied consent in s 122(4) to exclude, by necessary intendment, implied consent from the reference to consent in s 122(1).
32 In my view, the majority in Telstra were correct in concluding, at 168, that the Evidence Act 1995, s 122(1) is to be construed as reaching to cases in which the client or party concerned is deemed to have consented to the disclosure of otherwise privileged material in terms of the common law rule.
33 This approach has been adopted in a number of single judge decisions. In Wayne Lawrence Pty Ltd v Hunt [1999] NSWSC 1044, Hodgson CJ in Eq at [12] accepted that the decision of the majority in Telstra correctly interpreted and applied the Evidence Act 1995, s 122(1). In Garratt's Ltd v Thanga Thangathurai [2002] NSWSC 39, Bergin J concluded at [51] that consent for the purpose of the sub-section included conduct amounting to imputed or implied waiver. Those terms appear to be used interchangeably in the authorities. In Fort Dodge Australia Pty Ltd v Nature Vet Pty Ltd [2002] FCA 501 at [10], Hely J, while acknowledging that the issue before him in ancillary process was one of waiver of privilege at common law rather than by reference to s 122(1), observed that there was little difference between the issue as to whether a party had given its implied consent to the disclosure of the substance of evidence over which privilege was claimed as that term was used in the provision, or whether a party's conduct amounted to an imputed waiver at common law. His Honour cited Bergin J's judgment in Thanga. In BP Australia Pty Ltd v Nyran Pty Ltd [2002] FCA 1302, Nicholson J at [8] concluded that he must apply the common law of imputed waiver, but followed Telstra in saying that s 122(1) was to be understood in terms of the common law on that topic. Campbell J came to the same conclusion in United Rural Enterprises v Lopmand [2002] NSWSC 1142 at [12]. The decisions are discussed without dissent by Allsop J in DSE (Holdings) Pty Ltd v Intertan Inc (2003) 127 FCR 499 at [102]-[111]. McDougall J came to the same conclusion in Singapore Airlines v Sydney Airports Corporation [2004] NSWSC 380 at [52], [56]. And see my judgment in Wyadra Pty Ltd v Mailler (No 2) [2005] NSWSC 88 at [6].
34 It was submitted that decisions relating to ancillary process were of little assistance as they applied the common law principle and not that under the Evidence Act 1995, s 122(1).
35 A number of things can be said of that submission. First, it does not apply to New South Wales decisions on ancillary process since 1 October 1999 because the Supreme Court Rules 1970 imported the provisions of the Evidence Act 1995 into ancillary process. Secondly, as was established in Telstra and referred to in Fort Dodge there is little difference between the two because the common law principle of implied waiver is encompassed within consent for the purposes of s 122(1). Thirdly, United Rural Enterprises concerned an objection to evidence and did not involve ancillary process.
36 In my view the single judge decisions that have followed Telstra have conformed to it and, in particular, have accepted that the Evidence Act 1995, s 122(1) is to be construed as including implied waiver of client legal privilege within consent.
37 In Telstra, the majority held, at 168, that where a party relies on a cause of action an element of which is the party's state of mind, the party is taken to have waived privilege in respect of legal advice that the party had before or at the time of the relevant events material to the formation of that state of mind. Their Honours based this conclusion on fairness. At 166 they said:
"A party who initiates an undue influence case puts in issue in the proceeding the quality of his or her consent or assent ( Commercial Bank of Australia Ltd v Amadio (1983) 151 CLR 447 per Deane J at 474). The quality of such consent or assent will ordinarily be affected by relevant legal advice received by the party. The principle that requires that in such circumstances the party not be entitled to maintain the confidentiality of such advice is one of fairness which goes to the integrity of the legal process. To allow a party to put in issue the quality of his or her consent or assent whilst, at the same time, withholding evidence relevant to that issue, would be to allow him or her unfairly to handicap the opposing party to the proceeding, and to comprise the ability of the court realistically to determine the issue."
38 Hodgson CJ in Eq in Wayne Lawrence was of the view that it was not every assertion of belief that gave rise to implied waiver and the significance of the belief to the case, the relevance of the reasonableness of the belief to the case, and the probability of legal advice being relevant to the holding of the belief, or to its reasonableness, must be taken into account. His Honour said at [12]:
"Accepting that the decision of the majority in that case correctly interprets and applies s 122(1), it seems to me still that the question of whether the advancing of a person's state of mind is to be taken as consenting to the giving of evidence of confidential communication, or as waiving privilege, is a matter of degree in each case. It does not seem to me that the assertion of a belief must, in all circumstances, be taken as consenting to evidence being led of any legal advice or confidential communication that could be relevant to whether such a belief was held or the reasonableness of such belief. It seems to me that factors relevant to whether that consent is to be considered as having been given, or whether privilege is taken to have been waived, would include the significance of the belief to the case as a whole; the relevance of the reasonableness of the belief to the case as a whole; the probability or otherwise of the legal advice being relevant to the holding of that belief, or being relevant to its reasonableness; and in circumstances where the Court inspects the legal advice in question in order to make a decision, the extent to which the legal advice does in fact bear upon the holding of the belief or its reasonableness, and the extent to which the legal advice relevant to those matters is inextricably bound up with legal advice going to other questions as to which there has been no consent or waiver. It seems to me that, on the basis of all those matters at least, the Court has to make a judgment as to what is reasonable, and what is fair in the particular case."
