Relevant principles - implied or issue waver
6 The relevant principles in relation to implied waiver are, at least now, relatively easy to state. They are not, however, always so easy to apply. This matter is a case in point.
7 As this application is made pre-trial, the common law of legal professional privilege and waiver applies: Esso Australia Resources v Commissioner of Taxation (1999) 201 CLR 49 at [17]-[28] and [64]. At common law, a person who would otherwise be able to make a claim of privilege in respect of a communication may cease to be able to maintain that claim by reason of conduct that expressly or impliedly waives that claim. In the case of implied waiver, the basic principle turns on whether the conduct on the part of the holder of the privilege is inconsistent with the maintenance of confidentiality.
8 In Mann v Carnell (1999) 201 CLR 1 at [29] (Mann), the principle of implied waiver was put by the majority of the High Court in the following terms:
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… What brings about the waiver is the inconsistency, which the courts, where necessary informed by consideration of fairness, perceive, between the conduct of the client and maintenance of the confidentiality; not some overriding principle of fairness operating at large.
9 The authorities in relation to implied waiver establish that a relevant inconsistency with the continued confidentiality of a communication can arise where the privilege holder directly or indirectly puts in issue the character or contents of the communication in the litigation. It is unnecessary to refer to the relevant authorities at length. They were exhaustively reviewed by Allsop J (as his Honour the Chief Justice then was) in DSE (Holdings) Pty Limited v Intertan Inc (2003) 127 FCR 499 (DSE) and by the Full Court of this Court in Commissioner of Taxation v Rio Tinto Limited (2006) 151 FCR 341 (Rio Tinto). In Rio Tinto, the Full Court put the guiding principle in the following terms at [52]:
These authorities show that, where issue or implied waiver is made out, the privilege holder has expressly or impliedly made an assertion about the contents of an otherwise privileged communication for the purpose of mounting a case or substantiating a defence. Where the privilege holder has put the contents of the otherwise privileged communication in issue, such an act can be regarded as inconsistent with the confidentiality that would otherwise pertain to the communication.
10 In DSE, Allsop J said (at [58]) that an implied waiver will arise where:
the party entitled to the privilege makes an assertion (express or implied), or brings a case, which is either about the contents of the confidential communication or which necessarily lays open the confidential communication to scrutiny and, by such conduct, an inconsistency arises between the act and the maintenance of the confidence, informed partly by the forensic unfairness of allowing the claim to proceed without disclosure of the communication.
11 Whilst DSE was decided before Mann, the Full Court in Rio Tinto at [61] cited with approval Allsop J's "somewhat more descriptiv[e]" statement of the governing principle.
12 The governing principle of implied waiver requires a "fact-based inquiry": Rio Tinto at [61]. Each case will turn on its own facts and circumstances: Rio Tinto at [45], [47]. The Court is required to "analyse the acts or omissions of the privilege holder that are said to be inconsistent with the maintenance of the privilege": Rio Tinto at [45]. Other cases in which implied waiver has been considered provide limited guidance unless they arise out of similar facts: Rio Tinto at [45].
13 Three points relevant to the application of the relevant principles of implied waiver to the facts and circumstances of this matter should be emphasised. First, it is at least questionable whether legal advice can properly be said to be an issue in a proceeding merely because it might be relevant to an issue in the proceedings: Adelaide Steamship Co Limited v Spalvins (1998) 81 FCR 360 at 371: cited with approval in Rio Tinto at [53]. In Council of the NSW Bar Association v Archer (2008) 72 NSWLR 236, (Archer) Hodgson JA said, at [48]:
It is not enough to bring about a waiver of client legal privilege that the client is bringing proceedings in which the content of the privileged communications could, as a reasonable possibility, be relevant and of assistance to the other party. For the client to do this is not inconsistent with the maintenance of the privilege, and does not give rise to unfairness of the type in question. What would involve inconsistency and relevant unfairness is the making of express or implied assertions about the content of the privileged communications, while at the same time seeking to maintain the privilege. In this respect, it may be sufficient that the client is making assertions about the client's state of mind, in circumstances where there were confidential communications likely to have affected that state of mind.
14 The second point to emphasise relates to the last sentence of the passage from the judgment of Hodgson JA in Archer that is extracted in the previous paragraph. Sage, in its submissions, places particular emphasis on this sentence and the approval and emphasis given to it by the NSW Court of Appeal in Cooper v Hobbs [2013] NSWCA 70 (Cooper), McColl JA (Bergin CJ in Eq agreeing) at [72]. Sage submits, in effect, that this sentence is directly applicable to this matter because the applicants are making assertions in their pleadings about their state of mind in circumstances where confidential communications are likely to have affected that state of mind.
15 Four observations can, however, be made about this sentence in Hodgson JA's judgment in Archer. First, Hodgson JA uses the word "may", not "will". His Honour was not suggesting that all cases where assertions are made about a client's state of mind in circumstances where privileged documents are likely to have affected that state of mind will give rise to an implied waiver. Second, this is supported by the fact that, as pointed out by the Full Court in Rio Tinto, each matter will turn on its own facts and not much is to be gained by reference to other implied waiver cases unless they arise out of similar facts. Third, the facts and circumstances in both Archer and Cooper were significantly different to the facts of this case; and fourth, generalisations about types of cases, including cases where a party puts its state of mind in issue, should not distract from the primary question. As the Full Court in Rio Tinto put it (at [65]):
As the previous examination of the authorities shows, the question is not whether the Commissioner has put his state of mind in issue but whether he has directly or indirectly put the contents of the otherwise privileged communications in issue in the litigation, either in making a claim or by way of defence. Put another way, to adapt Allsop J's language in DSE, has the Commissioner (being the privilege holder) made an assertion as part of his or her case in the litigation that lays open the privileged documents to scrutiny, with the consequence that an inconsistency arises between the making of the assertion and the maintenance of the privilege?
16 The third point relating to the application of the principles of implied waiver to the facts and circumstances of this matter concerns the situation where applied waiver is asserted on the basis that a party has pleaded a case which puts its state of mind, including reliance, in issue. In such cases, Sage relies on the so called "evaluative approach" of Hodgson CJ in Eq in Wayne Lawrence Pty Limited v Hunt [1999] NSWSC 1044 (Wayne Lawrence). In Wayne Lawrence, Hodgson CJ in Eq said (at [12]):
[I]t seems to me still that the question of whether the advancing of a person's state of mind is to be taken as consenting 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 to 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.
17 Wayne Lawrence was decided before Mann, which explains the reference, in the last sentence of the above extract, to the relevant judgment of the court being "what is reasonable, and what is fair in the particular case". Nonetheless, in Chen v City Convenience Leasing Proprietary Limited [2005] NSWCA 297 (Chen), Gzell J (with whom Bryson JA and Windeyer J relevantly agreed), having referred to the judgment of Hodgson CJ in Eq in Wayne Lawrence, said (at [41]):
I doubt that a different result will follow from the sort of question referred to in Wayne Lawrence and the sort of question that needs to be answered in order to determine whether there is inconsistency between the conduct of a party and maintenance of client legal privilege as discussed in Mann. In a case like the present one in which reliance upon representations is alleged, questions such as the following need to be explored: Were representations made to the party by and 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 losses or damage alleged to have been suffered?
18 The approach of Gzell J in Chen also appears to have met with the approval of Besanko J in SA E.Med Pty Ltd v Calvary Healthcare Adelaide Ltd (No 2) [2011] FCA 835 at [23]-[25].
19 A number of points may be made in relation to this. First, whilst it is correct, as Gzell J pointed out, that in DSE Allsop J referred to the relevant passage from Wayne Lawrence as part of his Honour's extensive review of the authorities, all his Honour said in relation to Wayne Lawrence was (at [103]) "[i]t is clear from these passages that his Honour was of the view that more was involved in the assessment than merely the putting of the matter in issue": see also in this respect Sackville J in Seven Network Ltd v News Ltd (2006) 227 ALR 704 at [41] (Seven Network). Second, whilst the Full Court in Rio Tinto referred with approval to much of what was said by Allsop J in DSE, the Full Court did not refer to Wayne Lawrence.
20 More significantly, I have some difficulty reconciling the so called evaluative approach with other statements made by Allsop J in DSE and the approach taken by the Full Court in Rio Tinto. The question posed in the passages from Wayne Lawrence and Chen in my view tend to suggest that in cases where a state of mind is pleaded by a party and it is likely that legal advice which might be relevant to that state of mind was obtained by that party, it is likely that implied waiver will be established. Yet in DSE, Allsop J said, after reviewing the authorities decided prior to Mann, (at [95]):
I would have thought that it is too broad a statement to say that a pleading of a state of mind to which legal advice is or might be materially relevant is an adequate surrogate for the expression of principle in Mann v Carnell.
21 His Honour also said (at [97]) that the view that "relevance to an issue is the proper test is, as a general proposition, difficult to reconcile with Mann v Carnell". His Honour also expressed agreement with what was said by Heerey J in Equuscorp Pty Limited v Kanisha Corp Limited [1999] ATPR 41-697 at 42-894, including that "[t]he bare fact of asserting reliance does not expressly or impliedly assert that the plaintiff relied, or did not rely, on some privileged communication".
22 In my opinion, there may be no difficulty with the evaluative approach in Wayne Lawrence and Chen if the questions that are posed are seen as no more than questions that might assist in determining the ultimate question, namely, whether the privilege holder has expressly or impliedly made an assertion about the contents of an otherwise privileged communication for the purpose of mounting a case or substantiating a defence. In my view, however, the questions have a tendency to distract or deflect attention from that test. The questions posed as part of the so-called evaluative approach should not be used as a surrogate for the expression of principle in DSE and Rio Tinto.
23 I note in this context that in Seven Network, Sackville J, whilst his Honour ultimately did not need to decide the point, expressed some doubt that the evaluative approach "precisely reflects the content of the inconsistency principle" (at [46]).
24 Whatever may be the position in relation to the evaluative approach in Wayne Lawrence and Chen, it is, in my opinion, tolerably clear that the mere fact that a party pleads a cause of action that includes their state of mind as a material fact, or otherwise puts their state of mind in issue in the proceedings, does not necessarily give rise to an implied waiver in respect of legal advice that may have been received by the party, even if that legal advice may be relevant to the party's state of mind. This was the position taken by Yates J in Ferella v Official Trustee in Bankruptcy (2010) 188 FCR 68 at [65] where his Honour said:
However the question is not simply whether the holder of the privilege has put that person's state of mind in issue but whether that person has directly or indirectly put the contents of the otherwise privileged communication in issue: see [Rio Tinto] at [65]. Indeed, even the fact that the holder privilege makes clear that the advice was relevant or contributed to a particular course of conduct would not be sufficient to waive the privilege unless, possibly, the contents of the legal advice (and not merely the fact of the advice) are specifically put in issue by relying on the contents of the advice to vindicate a claimed state of mind: [Rio Tinto] at [67].
25 Likewise in Austral Dutch Kaolin Pty Ltd v Hanjin P&C Co Ltd [2011] FCA 638 at [22], Greenwood J said:
As legal professional privilege is an important common law right or common law immunity (Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission (2002) 213 CLR 543 at [11], [44] McHugh J [85] Kirby J; Baker v Campbell (1983) 153 CLR 52 at 74) and common law principles apply to these interlocutory questions (Mann v Carnell [27], [41], [143] and [144]), a party ought not to be denied that right as a result of an implied construct simply by pleading a claim to a remedial right based upon a cause of action in which a state of mind is put in issue unless the party expressly pleads reliance upon a privileged communication as a material fact (or particularises a material fact by reference to an otherwise privileged communication) or the very nature of the claim itself demonstrates clear inconsistency of treatment such as where a client sues his or her lawyer for negligence asserting a sequence of instructions and at the same time seeks to deny, on the ground of legal professional privilege, the disclosure by his or her lawyer of those communications in a forensic analytical process.
26 In this passage, Greenwood J refers to an example of a claim the very nature of which demonstrates inconsistency with the maintenance of confidentiality in respect of otherwise privileged communications. The example given by Greenwood J is a case where a client sues a lawyer for negligence. An action for negligent advice will put in issue the very advice received by the client. Other examples of such actions include some actions raising allegations of undue influence or actions for rectification where the content of a communication between the lawyer and client or the content of advice received by the client is directly raised by the nature of the allegation. The decision in SA E.Med provides an example of such a rectification case. In such cases, by commencing the action the privilege holder puts in issue the content of the very advice received: see Adelaide Steamship at 371-372. However, as the Full Court observed in Rio Tinto, it is dangerous to generalise from other cases of implied waiver unless they arise from the same facts. There is no closed or categorical list of types of actions that by their very nature give rise to implied waiver. Each case will turn on its own facts and circumstances.
