Thus, ordinary notions of fairness require that an assertion of the effect of privileged material or disclosure of part of its contents in the course of proceedings before a court or quasi-judicial tribunal be treated as a waiver of any right to resist scrutiny of the propriety of the use he has made of the material by reliance upon legal professional privilege.
17 In Standard Chartered Bank v. Antico (1995) 36 NSWLR 87 at 94-95 Hodgson J stated the principle in this way.
I think it would be consistent with Attorney-General for the Northern Territory v Maurice to formulate the principle in Thomason in this way. If a party, by pleadings or evidence, expressly or impliedly makes an assertion abut the content of confidential communications between that party and a legal adviser, then fairness to the other party may mean that this assertion has to be taken as a waiver of any privilege attaching to the communication.
18 I respectfully adopt this formulation. See too Ampolex Limited v. Perpetual Trustee Co. (Canberra) Limited (1995) 35 NSWLR 405 at 411. Telstra Corporation v. B.T. Australasia (1998) 85 FCR 152 at 167-168 (Branson and Lehane JJ) may state the principle more broadly.
19 The Telstra case was a decision on the Evidence Act (Cth), not on the common law position. Notwithstanding the respect which should be accorded to a decision of the Full Court of the Federal Court on a matter relating to the Uniform Evidence Acts, the present proceedings are not affected by that Act and there is a clear basis in authority in New South Wales under the general law, including the decision of Hodgson J, for the view which I follow.
20 The effect of commencing the 1996 proceedings must be considered in the context of the controversy and litigation of which the proceedings are part; without the context it could not be concluded that privilege was waived simply by commencing proceedings and claiming, as against the lawyers involved and no other person, that there had been breaches of duty on the part of those lawyers. However, in the context of the whole controversy, including the 1990 proceedings and the present proceedings commenced in 1994, which encompass allegations that the financier, the solicitors who acted or purportedly acted for the plaintiffs on the lending transaction and five directors or officers of the plaintiffs are liable to the plaintiffs, bringing proceedings against Freehills over the conduct of the 1990 proceedings made it probable that those persons or some of them would become the subject of claims for contribution, as indeed they have been. The plaintiffs could, if they had decided to sue Freehills at the time of commencing the 1994 proceedings or at an early stage in those proceedings, have joined Freehills as defendants. The course which they chose of suing Freehills in 1996 produced the likelihood that the contribution of the defendants in the 1994 proceedings and of Freehills to the alleged losses of the plaintiffs would become contentious.
21 In this regard I was referred to some observations in Goldberg v. Ng (1996) 185 CLR 83 at 98, regarding imputed waiver where there are two or more distinct proceedings which are related; that appears to me to be the present position. By bringing the 1996 proceedings the plaintiffs set off a chain of claims and litigation which was fairly certain to lead as it has in fact led to involvement of a number of parties other than the plaintiffs themselves and their former lawyers, and to the need to establish all the circumstances of decisions relating to the conduct of the 1990 proceedings for the purpose of reaching any conclusions about causation of loss and contribution.
22 The connection between the allegations in the 1996 proceedings and Freehills' allegations in the 2000 proceedings was referred to in argument as "the circle". The plaintiffs' counsel contended that by the time the circle came back the issues and the parties had changed to such a degree that there was no implied waiver. I have not accepted that argument in view of what should be regarded as the inevitability that the circular course would be followed once the plaintiffs commenced the 1996 proceedings.
23 In relation to damages it seemed to me, as I observed during the hearing, that the claims for damages made by the plaintiffs in the 1994 proceedings might well have opened up examination of the facts relating to the constitution of the 1990 proceedings and the manner in which they were conducted as relevant to the causation of loss; a particularly clear illustration of that possibility is that the plaintiffs claimed the legal costs of the 1990 proceedings as part of their claims for damages in the 1994 proceedings. This claim on its face extends both to costs incurred by the plaintiffs to their own lawyers, and costs which the plaintiffs were required to pay under costs orders. (In this regard I was told by the Seventh Defendant's counsel that the claim for costs is no longer pressed by the plaintiffs as against the Seventh Defendants. However there was no indication that the claim for costs as damages has otherwise been abandoned). It appears to me that the claim that costs be included in the damages necessarily opens up the issue whether the costs were reasonably incurred; at least by implication the plaintiffs must allege that they were reasonably incurred, which brings the circumstances which led to their being incurred within the area of facts which in fairness should be open to examination.
24 Counsel for Nippon Credit also relied on the terms of para 3 of the affidavit of Maria Occhiuto sworn on 28 August 1991 in proceedings in the High Court of New Zealand between Nippon Credit as plaintiff, Girvan Corporation (New Zealand) Limited as defendant and counter-claim plaintiff, and Maronis Holdings Limited as second counter-claim plaintiff. That paragraph dealt with events at an interlocutory hearing before McLelland J in the 1990 proceedings which were said to have included a concession by Maronis Holding's counsel about what was the sole point in those proceedings. In my opinion the use made of that part of the affidavit does not of itself constitute a ground on which waiver of privilege should be imputed to the plaintiffs, either generally or in respect of some narrowly defined range of facts relating to that interlocutory application and the concession alleged to have been made. I see no necessary involvement of the basis in instructions and advice for counsel's statement to McLelland J in what was put forward in that affidavit.
25 Thus far these reasons deal with matters which were argued before me on Friday 18 August. When on 21 August I told the parties that I had decided, for reasons to be published later, that privilege had been waived by Maronis Holdings and that inspection should be allowed, counsel for the plaintiffs recurred to a possibility, which he had mentioned in argument on 18 August, that there may be documents among those produced by Freehills which relate only to the New Zealand proceedings, or to other later legal business, and not to the 1990 proceedings. Production of such documents would be excessive to the call in the subpoena which expressly calls for documents relating to the 1990 proceedings. I then told counsel that the plaintiffs should identify any documents for which this contention was made, and on 22 August counsel produced three volumes of documents which have been separated from the documents produced on subpoena by Freehills, and claimed legal professional privilege against their being inspected. As I announced on 23 August I inspected these documents and decided that they should not be inspected by other parties. My inspection was not rigorous, and I may permit a lawyer representing the First Defendant to inspect them or some of them, after giving undertakings limiting the use which may be made of any information contained in them. If the First Defendant desires to take this course I will re-open my consideration.
26 On 21 August counsel for the plaintiffs also contended that the documents produced may include documents in respect of which Girvan New Zealand which was not a party to the 1990 proceedings, is entitled to legal professional privilege. The possibility that there may be such documents was the subject of some submissions on 18 August. After I allowed an opportunity for further inspection, plaintiffs' counsel contended that four of the documents produced fell into this category and claimed legal professional privilege of Girvan New Zealand against their inspection. Counsel identified these documents by their numbers in the List of Contents of Files annexed to the affidavit of Susan Lever in support of the claim for privilege; and produced a copy of the list with markings indicating what claims were made. In the marked list (Interlocutory Ex X), documents for which no claim for privilege was pressed having regard to the decision which I announced on 21 August bear a distinct mark; the small number of documents for which it is conceded that there never was a privilege claim are also indicated, and documents for which a privilege claim is still maintained are indicated with the letter "p".
27 The claim of privilege of Girvan New Zealand related to documents numbered 9, 15, 18 and 422. I have inspected those documents. Documents 9 and 15 are letters from Shanahan Partners, barristers and solicitors in Auckland New Zealand, to Messrs Freehill Hollingdale and Page dated 9 and 19 March 1990 which in effect refer Girvan New Zealand and Maronis Holdings to Freehills for advice and action in New South Wales. The letter of 9 March 1990 contains a statement that Shanahan Partners acted for Girvan New Zealand, and its contents clearly show contemplation that Freehills would act in the interests of Maronis Holdings as well. The same contemplation is even clearer from the terms of the letter of 19 March 1990. Document 18 is a Memorandum dated 21 March 1990 from one solicitor in the office of Freehills to another listing and reviewing possible causes of action and further steps and information. Document 422 is a bundle of handwritten memoranda containing a miscellany of facts, matters for inquiry and observations on facts known. The terms of all these documents show more or less distinctly that they were prepared on the understanding that Freehills were to act or acted on the instructions of and in the interests of both the plaintiff companies, and not solely in relation to Maronis Holdings, the focus of attention being the prospects of attacking the mortgage and other obligations which Maronis Holdings had incurred. The position taken was that it appears from these documents that Girvan New Zealand as well as Maronis Holdings was a client of Freehills in 1990, and that any waiver of legal professional privilege would be ineffective unless it was a waiver made by both of them.
28 It is plain not only from the terms of the documents but from the whole circumstances of the litigation which have become known to me during the lengthy hearing thus far that the first and second plaintiffs acted then and at all times ever since in a very close association of action and interest; they have always had the same lawyers to represent them, and Maronis Holdings is indirectly the wholly owned subsidiary of Girvan New Zealand. They have been very closely associated in the conduct of all legal business known to me relating to the controversy. Girvan New Zealand is not a party to the 1996 proceedings against Freehills, but since 1994 until the present has at all times been closely associated, and practically identified with Maronis Holdings in the conduct of the present litigation.
29 While it is easy enough to recognise the very close association between the parent company and its subsidiary where the parent company in effect brings the subsidiary with it to lawyers who are to act for both of them and arranges for the lawyers to act for the subsidiary, it is not easy to give the association any well-known legal characterisation. What has taken place is very like a situation of agency where Girvan New Zealand acted on behalf of Maronis Holdings in taking the controversy to Freehills in 1990 and conveying instructions to them; yet it is highly unlikely that an actual relationship of agency was created and there is no evidence of such an agency; the strong interest of Girvan New Zealand in extricating Maronis Holdings from its position is a sufficient explanation of what took place without supposing that there was an actual conferral of agency authority.
30 Plaintiffs' counsel referred me to the consideration of joint privilege and waiver in the judgment of Sheller JA in Farrow Mortgage Services Pty Ltd (in Liq) v. Webb & Ors (1996) 39 NSWLR 601, particularly at 608. Justice Sheller first considered the privilege position where one of the group of persons who are in a formal legal relationship communicates with a legal adviser about a matter in which the members of the group share an interest; his Honour gave the examples of one partner communicating about the affairs of the partnership and one trustee communicating about the affairs of the trust, and said of persons in that position that their privilege was one inseverable right. His Honour said "Logically the joint nature of the privilege means that all to whom it belongs must concur in waiving it." Justice Sheller distinguished from joint privilege circumstances where parties have a shared or similar interest in the subject of communications between one or more of them and a legal adviser and observed "… disclosure amongst persons with a common interest, as it has been described, need not result in a waiver of privilege by the party making it."
31 The present facts do not fit neatly within either of the categories stated by Sheller JA but more closely resemble the first category of joint privilege. As his Honour observed, logically the joint nature of the privilege means that all to who it belongs must concur in waiving it. In my view this observation should not be understood to deal exhaustively with the circumstances in which waiver can take place, because it is to be understood, in cases of implied waiver, which are the cases usually encountered, that intention and concurrence in intention to waive are not necessary, and that, echoing the words of Gibbs CJ in Attorney-General v. Maurice (at 481), where there is no intentional waiver the question whether a waiver should be implied depends on whether it would be unfair or misleading to allow a party to assert that material is privileged from production. The acts from which I have concluded as against Maronis Holdings that a waiver should be implied are not all acts by or on behalf of Girvan New Zealand and did not take place in circumstances in which it could be found that Girvan New Zealand intentionally concurred in waiving a joint privilege. Yet the association between the two in their conduct of legal business in relation of the controversy is close, indeed complete, and has been so close since March 1990 that they should not in my opinion be considered separately when deciding whether it would be unfair or misleading to allow the privilege to be asserted. In my opinion I should not allow the claim that Documents 9, 15, 18 and 422 should not be inspected because of legal professional privilege.
