Waiver
The real basis upon which his Honour determined that Mrs Carnell was not entitled to the protection afforded by O 34A r 2 was that, even assuming that the documents sought by Dr Mann were protected by client legal privilege, that privilege had been waived by the publication of those documents by Mrs Carnell to Mr Moore.
His Honour dealt with the doctrine of waiver by referring initially to Attorney-General (NT) v Maurice (1986) 161 CLR 475. He observed that in that case the question had been whether disclosure of some documents which were subject to legal professional privilege implied waiver of the privilege in relation to other associated documents. In such a situation waiver is to be implied when, by some conduct on the part of the privilege holder, it becomes unfair to maintain the privilege. His Honour referred in particular to the joint judgment of Mason and Brennan JJ at 487-8.
"The limiting effect of legal professional privilege on the availability of evidence otherwise relevant is confined, inter alia, by the doctrine of waiver. A litigant can of course waive his privilege directly through intentionally disclosing protected material. He can also lose that protection through a waiver by implication. An implied waiver occurs when, by reason of some conduct on the privilege holder's part, it becomes unfair to maintain the privilege. The holder of the privilege should not be able to abuse it by using it to create an inaccurate perception of the protected communication. Professor Wigmore explains:
"[W]hen his conduct touches a certain point of disclosure, fairness requires that his privilege shall cease whether he intended that result or not. He cannot be allowed, after disclosing as much as he pleases, to withhold the remainder." (Wigmore, Evidence in Trials at Common Law (1961), vol. 8, par. 2327, p. 636)
In order to ensure that the opposing litigant is not misled by an inaccurate perception of the disclosed communication, fairness will usually require that waiver as to one part of the protected communication should result in waiver as to the rest of the communication on that subject-matter: see Great Atlantic Insurance Co. v. Home Insurance Co. [1981] 1 W.L.R. 529; [1981] 2 All E.R. 485.
Hence, the implied waiver inquiry is at bottom focused on the fairness of imputing such a waiver."
The primary judge proceeded, with reference to Maurice (supra):
"There is nothing in the judgment, however, to support the proposition that disclosure of a privileged document to a communicant does not waive privilege as far as that communicant is concerned. Notions of fairness and justice are irrelevant, unless it is to be suggested that the waiver goes beyond the particular disclosure. Nothing of that sort is suggested in the present application."
A little further on, his Honour continued:
"The confidentiality is between client and lawyer. That confidentiality is lost if the document is passed on to a third party who has no place in the client-lawyer relationship or the matters in respect of which legal advice or assistance is sought. It is lost whether the document is passed on by the client or by the lawyer, and whatever be the understanding between the third party and the client or lawyer who passes it on about how the document is to be treated. It is the occasion of publication between lawyer and client which confers the privilege, but the privilege does not extend to republication unless republication occurs on a privileged occasion."
The difficulty with his Honour's analysis is that it fails to take into account the effect of the Evidence Act upon the doctrine of waiver. Though his Honour used the expression "client legal privilege" on several occasions in his reasons for judgment (this being the terminology used in the Act), he did not refer specifically to any of the provisions which deal with that form of privilege or, more importantly, with the loss of that form of privilege.
The starting point when considering the treatment of "waiver' under the Evidence Act is the definition of "confidential communication" in s 117(1) of the Act. That subsection provides in part :
"…a communication made in such circumstances that, when it was made:
(a) the person who made it; or
(b) the person to whom it was made;
was under an express or implied obligation not to disclose its contents, whether or not the obligation arises under law:
…"
The expression "confidential document" is defined in analogous terms.
Sections 118 and 119 of the Evidence Act create new statutory privileges in relation to the provision of legal advice and the provision of professional legal services. Section 120 provides a privilege for parties who are unrepresented in litigation.
The most notable feature of the modification to the common law which is brought about by these sections is, as has been noted, the substitution of the "dominant purpose" test for the "sole purpose" test.
Another important change brought about by the introduction of the Evidence Act is that the common law principles surrounding the doctrine of waiver in its application to legal professional privilege are not replicated. Section 122 of the Act provides as follows:
"Loss of client privilege: consent and related matters
122.(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 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 given by police officers)."
Subsection 122(1) provides, in terms, that the privileges conferred by s 118, s 119 and s 120 do not prevent the adducing of evidence given with the consent of the client or party concerned. The logic of this subsection is perhaps open to question since the privileges conferred by those provisions do not arise unless there is an "objection" by a client in the case of s 118 and s 119, or, in the case of s 120, by a party. In any case in which evidence is given with the "consent" of the client or party there would presumably be no "objection" by that person to its being given, and therefore no need for s 122(1).
In contrast to the broad principles of "fairness" laid down in relation to waiver of legal professional privilege in Maurice (supra), s 122(2) provides that the privileges in s 118 and s 119 are not available if the client or, in the case of s 120, the party, has "knowingly and voluntarily" disclosed the substance of the evidence to another person, subject to certain exceptions contained in s 122(2)(a), (b), (c) and (d), and s 122(5). Subsection 122(4) provides that the privileges in s 118, s 119 and s 120 are not available if the substance of the evidence has been disclosed with the express or implied consent of the client or, in the case of s 120, the party, to another person, again subject to certain, more limited exceptions contained in s 122(5).
The application of s 122 may well, in any given case, produce an entirely different outcome to that which would follow under the common law doctrine of waiver: Ampolex Ltd v Perpetual Trustee Co (Canberra) Ltd (1996) 40 NSWLR 12 at 18-24 per Rolfe J; Adelaide Steamship Co Ltd & Anor v Spalvins & Ors (1998) 152 ALR 418 at 425-6; BT Australasia Pty Ltd v State of New South Wales & Anor (No 8) (1998) 154 ALR 202 at 207-210 per Sackville J; and Telstra Corporation Ltd v BT Australasia Pty Ltd (1998) 156 ALR 634 at 644-9 per Branson and Lehane JJ. There is a useful discussion of this point in K Smark, "Privilege under the Evidence Acts" (1995) 18 UNSWLJ 95 at 97-101.
When Dr Mann's application to have Mrs Carnell produce the documents for inspection was dealt with by the primary judge on 2 April 1998, the decision of the Full Court of the Federal Court in Spalvins (supra) had not yet been reported. Judgment in that case had been delivered on 2 March 1998. It would appear that the judgment had not come to the attention of counsel.
Prior to the judgment in Spalvins being delivered there had been uncertainty as to whether the provisions of the Evidence Act dealing with privilege were applicable to interlocutory proceedings. Sections 118, 119 and 120 of the Act provide, in terms, that evidence is "not to be adduced". These provisions do not purport to deal with discovery, or with the return of subpoenas, or with any other ancillary processes. The Full Court in Spalvins resolved that uncertainty when it held that in such interlocutory proceedings it was the common law and not the Evidence Act that determined whether or not documents which were claimed to be privileged were required to be produced for inspection. The Full Court went on to hold, however, that the common law principles applicable to claims to privilege in jurisdictions in which the Evidence Act applied must be treated as having been modified so as to accord with the requirements of the Act. The provisions of the Act were said to apply "derivatively" to ancillary processes, modifying the common law in those jurisdictions in which the Act applied so as to accord with it.
In so holding, the Full Court followed the approach which had commended itself to McLelland CJ in Eq in Telstra Corporation v Australis Media Holdings [No 1] (1997) 41 NSWLR 277, and declined to follow the contrary views expressed by, among others, Foster J in Esso Australia Resources Ltd v Federal Commissioner of Taxation (1997) 150 ALR 117. Subsequently, the New South Wales Court of Appeal in Akins v Abigroup Ltd (1998) 43 NSWLR 539 followed the decision of the Full Court of the Federal Court in Spalvins. That decision by the Court of Appeal was handed down on 1 June 1998, just three days before the primary judge delivered his judgment in the present matter. On 24 July 1998 a Full Court of the Federal Court, by majority rejected a submission that the decision in Spalvins should not be followed: Telstra Corporation Ltd v BT Australasia Pty Ltd (supra) at 644 per Branson and Lehane JJ. Beaumont J dissented without considering whether Spalvins should be followed - see 642.
Had the decision of the Full Court in Spalvins been drawn to his Honour's attention during the course of the proceedings before him, his Honour undoubtedly would have dealt with the question of "waiver" in accordance with the requirements of s 122 of the Evidence Act. Regrettably, his Honour appears to have proceeded upon the assumption that waiver was governed by the common law, without any regard being given to the operation of the Act upon that doctrine. That was an error which necessitates setting aside the decision below. It also results in the rejection of Dr Mann's application.
