THE PRINCIPLES
27 Division 1 of Part 3.10 of the Evidence Act 1995 (Cth) (the 'Evidence Act') is concerned with client legal privilege. Section 118 provides that 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 confidential communication made between the client and a lawyer for the dominant purpose of the lawyer providing legal advice to the client (see also s 119). Section 122(1) provides that Div 1 of Part 3.10 does not prevent the adducing of evidence given with the consent of the client concerned. Nor does Div 1 prevent (subject to certain exceptions) the adducing of evidence if the client has 'knowingly and voluntarily disclosed to another person the substance of the evidence': s 122(2).
28 The circumstances in which client legal privilege or legal professional privilege may apply are not limited to the adducing of evidence in the course of a hearing in court: Mann v Carnell, at [19]. The privilege may be invoked in pre-trial proceedings, such as discovery, or in the course of a hearing but independently of the adducing of evidence. The High Court has held that s 118 of the Evidence Act is limited to the adducing of evidence and does not apply to the discovery of confidential communications made between lawyer and client either directly or by a derivative modification of the common law: Esso Australia Resources Ltd v Federal Commissioner of Taxation (1999) 201 CLR 49. Section 122 is similarly confined, since it is expressed as a qualification to the prohibitions for which Div 1 provides elsewhere. It follows that in the absence of legislation or rules of court, common law principles govern waiver of legal professional privilege at any stage prior to the adducing of evidence.
29 In the present case, it is necessary to take into account Federal Court Rules ('FCR'), O 33 r 11. Rule 11 provides as follows:
'Privilege
(1) Where the Court, by subpoena or otherwise, orders any person to produce any document or thing, and any person makes and substantiates sufficient lawful objection to production on grounds of privilege, the Court shall not compel production of that document or thing except production to the Court for the purpose of ruling on the objection.
(2) Where a question is put to a person in the course of examination, and any person makes and substantiates sufficient lawful objection on grounds of privilege to the question being answered, the Court shall not compel an answer to the question.
(3) Subrule (1) applies where an order is made for production to, and subrule (2) applies where a question is put to a person in the course of examination before the Court or any officer of the Court, or any examiner, or other person authorized to receive evidence, whether on a trial or hearing or on any other occasion.
…
(5) In this rule:
ground of privilege means a ground on which a person may rely to make an objection under Part 3.10 of the Evidence Act 1995.'
30 Subrule (5) of O 33 r 11 was inserted into the FCR in 2002 in conformity with a recommendation made by the Australian Law Reform Commission: Evidence (Report No. 38, 1987), App A; Seven Network Ltd v News Ltd [2005] FCAFC 125 (Seven (FC)), at [12], per Branson J. The effect of subrule (1), when read with subrule (5), is to apply Div 1 of Part 3.10 of the Evidence Act, rather than the common law, to a claim of client legal privilege in the circumstances identified in subrule (1). Div 1 includes s 122, which therefore determines whether privilege has been waived in those circumstances.
31 In the present case, orders for discovery were made which required the preparation of lists of documents, including the advices in respect of which Seven has claimed privilege ('the Advices'). Optus has now issued notices to produce in the course of the trial requiring Seven to produce the Advices to the Court.
32 A notice to produce has, in substance, the same coercive effect as a subpoena: O 33 r 12 (as to the effect of a subpoena see O 27 rr 2(1), 6(4)). It is clear enough that O 33 r 11(1) is intended to apply where a notice to produce is issued in the course of a trial - that is, at a time when the Court is authorised to receive evidence. As Branson J noted in Seven (FC), at [17], the effect of O 33 r 11:
'is to remove the obligation that would otherwise arise in these circumstances for an objection to the production of the document to be determined according to common law principles'.
33 In Telstra Corporation Ltd v BT Australasia Pty Ltd (1998) 85 FCR 152, Telstra sought production, by way of discovery, of documents which were subject to claims of legal professional privilege. The Court held, following earlier Full Court authority, that s 122 of the Evidence Act had a 'derivative' application to pre-trial discovery. (That proposition is no longer good law: Esso v FCT.) A majority of the Court (Branson and Lehane JJ) held (at 164) that 'consent' in s 122(1) includes circumstances in which legal professional privilege would be regarded as waived by reason of conduct on the part of the privilege holder which would render it unfair for the privilege to be maintained. The majority considered (at 166) that the common law imputed a waiver of privilege:
'if by reason of some conduct of [the privilege holder], it would be unfair to the other party, in a way which goes to the integrity of the legal process, for the privilege to be maintained'.
34 Branson and Lehane JJ also expressed the view (at 164) that 'consent' in s 122(1) of the Evidence Act includes the common law concept of imputed consent flowing from considerations of fairness. Their Honours observed (at 164) that:
'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 in the pre-existing common law with respect to legal professional privilege'.
35 In Mann v Carnell, the High Courtrestated the common law principles governing waiver of legal professional privilege. The joint judgment pointed out (at [28]) that 'waiver' is a vague term that often requires further definition according to the context. Their Honours said (at [28]-[29]) that:
'It is inconsistency between the conduct of the client and maintenance of the confidentiality which effects a waiver of the privilege. Examples include disclosure by a client of the client's version of a communication with a lawyer, which entitles the lawyer to give his or her account of the communication, or the institution of proceedings for professional negligence against a lawyer, in which the lawyer's evidence as to advice given to the client will be received.
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 operation of law". This means that the law recognises the inconsistency and determines its consequences, even though such consequences may not reflect the subjective intention of the party who has lost the privilege. … What bring 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.' (Emphasis added; citations omitted.)
36 Telstra v BT was decided before Mann v Carnell and Esso v FCT. As I have noted, the Full Court therefore proceeded on what has been held to be the erroneous assumption that Div 1 of Part 3.10 of the Evidence Act applies derivatively to pre-trial procedures. The majority also proceeded on the basis of what might be described as an incomplete statement of principle, in that the judgment assumes that common law waiver is essentially informed by considerations of fairness (as distinct from the inconsistency formula adopted in Mann v Carnell, at [29]).
37 Nonetheless, Telstra v BT has been widely accepted as laying down the correct general approach to the construction of s 122 of the Evidence Act. In Chen v City Convenience Leasing Pty Ltd [2005] NSWCA 297, a case in which the Supreme Court Rules applied the Evidence Act 1995 (NSW) to pre-trial procedures, Gzell J (with whom Bryson JA and Windeyer J agreed) said (at [31]) that the interpretation put forward in Telstra v BT 'must be correct'. Gzell J also cited (at [33]) a number of single judge decisions to the same effect: see also DSE (Holdings) Pty Ltd v Intertan Inc (2003) 127 FCR 499, at [102]-[111], per Allsop J.
38 There is, however, a second aspect to the approach taken by the majority in Telstra v BT that is material to the present case. Branson and Lehane JJ held (at 165) that common law waiver has the following operation:
'in cases in which the state of mind of a party [is] in issue in the proceedings, … evidence [can] be called to establish the terms of legal advice, relevant to that party's state of mind, provided to that party'. (Emphasis added)
39 Their Honours developed this analysis (at 166-167) as follows:
'Where, as in this case, a party pleads that he or she undertook certain action "in reliance on" a particular representation made by another, he or she opens up as an element of his or her cause of action, the issue of his or her state of mind at the time that he or she undertook such action. The court will be required to determine what was the factor, or what were factors, which influenced the mind of the party so as to induce him or her to act in that way. That is, the party puts in issue in the proceeding a matter which can not fairly be assessed without examination of relevant legal advice, if any, received by that party. In such circumstances, the party, by putting in contest the issue of his or her reliance, is to be taken as having consented to the use of relevant privileged material, or to put it another way, to have waived reliance on the privilege which such material would otherwise attract.'
Later they said (at 168) that:
'Where, … a party relies on a cause of action, an element of which is the party's state of mind (including the quality of the party's assent to a transaction) the party is taken to have waived privilege in respect of legal advice which the party had, before or at the time of the relevant events, material to the formation of that state of mind.'
Clearly enough, these holdings were informed by considerations of fairness which the majority considered underpinned common law waiver (see at 164). However, their Honours also said (at 167) that it was not:
'a consequence of the principle [stated at 166-167] that whenever a person's state of mind is relevant to an issue in proceedings, privilege is taken to be waived in relation to legal advice that may have played [a] part in the formation of that state of mind '.
40 In Wayne Lawrence Pty Ltd v Hunt [1999] NSWSC 1044, Hodgson CJ in Eq accepted that the majority in Telstra v BT correctly applied s 122(1) of the Evidence Act. Nonetheless, his Honour expressed the view (at [12]):
'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 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.'
41 Wayne Lawrence was decided before Mann v Carnell. It is therefore not surprising that Hodgson CJ in Eq took as his reference point 'what is reasonable, and what is fair in the particular case'. It would seem to be clear enough, however, that Hodgson CJ in Eq considered that more was required for a waiver of privilege than simply putting a state of mind in issue in circumstances where legal advice might be relevant to the formation of that state of mind: DSE v Intertan at [103], per Allsop J.
42 In Chen, Gzell J quoted the observation of Hodgson CJ in Eq with apparent approval. He also expressed the view (at [41]) that treating the question of waiver as a matter of degree was unlikely to be materially different from the sort of question that needs to be asked in order to determine whether there is inconsistency between the conduct of a party and the maintenance of client legal privilege as discussed in Mann v Carnell. Gzell J said (at [41]) that in a case in which reliance on representations is alleged, the following questions need to be explored:
'Were representations made to the party by or on behalf of the opponent? Does the party say that he or she relied upon the representations and altered his or her course of conduct? Is reliance upon the representations a central, or merely peripheral, aspect of the party's case? Is it likely that the party received legal advice that had a bearing on the allegation of reliance? Was it likely that the legal advice might raise doubts as to the allegations of reliance or any loses [sic] or damage alleged to have been suffered?'
43 In DSE v Intertan, Allsop J considered (at [95], [109]) that the inconsistency principle articulated in Mann v Carnell has the consequence that privilege will not be waived by a party merely because the party raises its state of mind as an issue and legal advice is likely to have contributed to that state of mind. His Honour appears to suggest (at [58], [61]) that the inconsistency required by Mann v Carnell will be present only where the party entitled to the privilege brings a case which is either about the contents of the privileged communication or necessarily lays open a confidential communication to scrutiny. However, his Honour recognised (at [62]) the danger of elevating the facts of particular cases into principles which might supplant or modify the governing principle laid down in Mann v Carnell.
44 The current position concerning s 122 of the Evidence Act, as I see it, is as follows:
(i) Telstra v BT holds that s 122 of the Evidence Act is to be read as incorporating common law principles of waiver. I am bound by that holding.
(ii) The majority in Telstra v BT interpreted the scope of common law waiver by reference to the guiding principle of fairness. That interpretation has now been overtaken by the authoritative statement of principle in Mann v Carnell at [29]. That is, what brings about waiver of privilege of common law is the inconsistency which courts, where necessary informed by considerations of fairness, perceive between the conduct of the client and the maintenance of confidentiality, not some overriding principle of fairness.
(iii) It follows that, despite what was said in Telstra v BT (at 166-167), the fact that the client pleads reliance on a representation does not necessarily result in the waiver of privilege in any legal advice that may be relevant to ascertaining the party's state of mind. To put the matter another way, the mere fact that legal advice may be material to an issue in the proceedings, even one raised by the client, does not establish that the conduct of the client is inconsistent with maintaining confidentiality in the privileged communications.
45 Mr Bannon's submissions, in substance, appeared to accept propositions (ii) and (iii). He said that he was content to adopt the formulation of Hodgson CJ in Eq in Wayne Lawrence (see [42] above) as the correct approach to the construction of s 122 of the Evidence Act. That formulation, as I have noted, qualifies the statement of principle in Telstra v BT.
46 The application of the principle stated in the High Court in Mann v Carnell isnot free from difficulty. The High Court gave two examples (at [28]) of waiver of privilege resulting from inconsistency between the conduct of a client and maintenance of confidentiality in the privileged communications. The first is the disclosure by a client of the client's version of a communication with his or her lawyer, which disclosure entitles the lawyer to give an account of the communication (Benecke v National Australia Bank (1993) 35 NSWLR 110). The second is the institution of proceedings by the client for professional negligence against his or her lawyer, in which case the lawyer's evidence as to the advice given to the client will be received: Lillicrap v Nalder & Son [1993] 1 All ER 724. These illustrations, although obviously not intended to be exhaustive, perhaps suggest that their Honours may have seen the inconsistency principle as having a relatively narrow application. In any event, it is not entirely clear that what might be described as the evaluative approach suggested in Wayne Lawrence, and adopted in Chen, precisely reflects the content of the inconsistency principle.
47 Seven's written submissions suggested that it was unnecessary to determine whether the reasoning in Telstra v BT continues to apply in an unmodified sense following the decision in Mann v Carnell. Given thosesubmissions and Optus' willingness to accept the statement of principle in Wayne Lawrence, I am content to proceed on the basis that that statement provides appropriate guidance in the present case.
48 It follows that, on this approach, the waiver of legal professional privilege on the grounds of implied consent will involve questions of degree. As Optus said in their submissions in reply, the Court will have to take a number of factors into account. These include:
· the centrality (or otherwise) to the proceedings of the issue to which the privileged communications are said to relate;
· if the issue involves a state of mind or belief, the likelihood that legal advice played a significant part in the foundation of that state of mind or belief; and
· whether there is any apparent inconsistency between the position taken by the party claiming privilege (whether at the trial or earlier) and the likely contents of the privileged communications.
