"... there must be pressure, (a) whose practical effect is that there is compulsion on, or lack of practical choice for, the victim; (b) which is illegitimate; and (c) which is a significant cause inducing the claimant to enter into the contract: see Universal Tankships Inc of Monrovia v. International Transport Workers' Federation[1983] 1 AC 366 at 400B-E and Dimskal Shipping Co SA v. International Transport Workers' Federation[1992] 2 AC 152 at 165 G. In determining whether there has been illegitimate pressure, the Court takes into account a range of factors. These include whether there has been an actual or threatened breach of contract; whether the person allegedly exerting the pressure has acted in good or bad faith; whether the victim had any realistic practical alternative but to submit to the pressure; whether the victim protested at the time; and whether he affirmed and sought to rely on the contract. These are all relevant factors. Illegitimate pressure must be distinguished from the rough and tumble of the pressures of normal commercial bargaining."
"A client who sues his solicitor invites the court to adjudicate the dispute and thereby, in my judgment, waives privilege and confidence to the extent that is necessary to enable the court to do so fully and fairly in accordance with the law including the law of evidence. I suspect that at the fringes each case will depend on its own facts. Normally the waiver will extend to facts and documents material to the cause of action upon which the plaintiff sues and the defendant's proper defence to that cause of action. The bringing of a claim for negligence in relation to a particular retainer will normally be a waiver of privilege and confidence for facts and documents relating to that retainer, but not without more for those relating to other discrete retainers"
"The waiver can only extend to matters which are relevant to an issue in the proceedings and, privilege apart, admissible in evidence. There is no waiver for a roving search into anything else in which the Solicitor or any other solicitor may have happened to have acted for the clients. But the waiver must go far enough, not merely to entitle the plaintiff to establish his cause of action, but to enable the defendant to establish a defence to the cause of action if he has one. Thus, it would extend to matters under earlier retainers, as in the hypothetical example I have given, which established that the experience of the client, was, to the knowledge of the solicitor, such that the solicitor was not in breach of duty as alleged."
"For my part, I would have difficulty in holding that the defendants should, as a matter of principle, be prevented from adducing evidence which is relevant to that issue. A proper interpretation of the waiver in this case is, in my judgment, one that embraces not only the documents and advice arising from the Heligan Manor transaction, but also documents or information otherwise subject to privilege which are relevant to the issues between the parties and it would be unfair to exclude."
"All of these established exceptions to the rules of privilege have a common denominator; in each instance, the party asserting the privilege placed information protected by it in issue through some affirmative act for his own benefit, and to allow the privilege to protect against disclosure of such information would have been manifestly unfair to the opposing party. The factors common to each exception may be summarized as follows: (I) assertion of the privilege was a result of some affirmative act, such as filing suit, by the asserting party; (2) through this affirmative act, the asserting party put the protected information at issue by making it relevant to the case; and (3) application of the privilege would have denied the opposing party access to information vital to his defense. Thus, where these conditions exist, a court should find that the party asserting a privilege has impliedly waived it through his own affirmative conduct.'"
"If the reasoning in Hearn v. Rhay was of general application it would involve a fundamental inroad into the scope of legal professional privilege. Waiver of privilege would operate if it could be established that the communications between the plaintiff and his solicitor were likely to be evidentially relevant to an issue and it would be unfair if the defendant did not have access to them in order to assist his defence. But, as I have already explained, the foundation of the waiver is not merely that the assertion of privilege leads to the inaccessibility of evidence relevant to a defence. It is the inconsistency of the plaintiff on the one hand opening the professional relationship to the inspection of the court and on the other hand seeking to enforce confidentiality so as to exclude communications to which the professional relationship between the same parties has given rise. Thus, whatever the United States courts now regard to be the scope of waiver of privilege, the reasoning in Hearn v. Rhay certainly does not represent English Law."
"As I read the judgment of Dillon LJ, in accepting the judge's formulation of the scope of the waiver Dillon LJ was accepting (a) that the fact which gives rise to the implication of waiver is the fact that the plaintiff has invited the court to adjudicate on the particular issue and (b) that implicit in that invitation is an acceptance on the part of the plaintiff that in making its adjudication the court must have access to all the evidential material which is required to enable it to do so fully and fairly. ... In my judgment the decision in Lillicrap v. Nalder is authority for the proposition that it is not a necessary condition of an implied waiver of privilege by a plaintiff that the documents in question should be privileged as between the plaintiff and the defendant. As I read the decision in Lillicrap v. Nalder, the principles expressed by the Court of Appeal in that case are applicable to privileged communications between a plaintiff and a third party."
"The same basic principle is relevant to this issue, that is, whether the original privilege has been lost because the state of mind of Mr Johnston, which may or may not have been influenced by the privileged material, is in issue. In the resolution of that issue it is necessary to investigate all relevant matters in his mind at the time in order to determine whether he was so induced by the alleged representations at all. Cognate to this is the question whether other factors constituted the inducement. The recommendations of Mr Miller and the terms of all advice concerning the recommendations which Mr Johnson says provided the material upon which he made his decision is obviously highly relevant to the enquiry. It would be grossly unjust to the plaintiff to deny him access to it in order to investigate and test the claim. Notwithstanding the high status of professional privilege and the careful protection which the law affords it, when the contents of a privileged communication become the subject of a legitimate and reasonable issue in the litigation, then the privilege is lost"
"Moreover, as I indicated earlier, Derrington J's decision and his reasoning is, in my judgment, entirely consistent with and covered by the decision of the Court of Appeal in Lillicrap v. Nalder. The same consideration applies, in my judgment, to the decision in the American case of Hearn v. Rhay considered by Colman J in NRG v. Bacon & Woodrow. It appears from the reports of those cases - although I must make it clear that in relation to Hearn v. Rhay I have only seen the report of the NRG case - that the principles of implied waiver based upon the contents of the pleadings in the action are substantially the same in each of the three jurisdictions."
"When a client sues a solicitor who has formerly acted for him, complaining that the solicitor has acted negligently, he invites the court to adjudicate on questions directly arising from the confidential relationship which formerly subsisted between them. Since court proceedings are public, the client brings that formerly confidential relationship into the public domain. He thereby waives any right to claim the protection of legal professional privilege in relation to any communication between them so far as necessary for the just determination of his claim; or, putting the same proposition in different terms, he releases the solicitor to that extent from the obligation of confidence by which he was formerly bound. This is an implication of law, the rationale of which is plain. A party cannot deliberately subject a relationship to public scrutiny and at the same time seek to preserve its confidentiality. He cannot pick and choose, disclosing such incidents of the relationship as strengthen his claim for damages and concealing from forensic scrutiny such incidents as weaken it. He cannot attack his former solicitor and deny the solicitor the use of materials relevant to his defence. But, since the implied waiver applies to communications between client and solicitor, it will cover no communication to which the solicitor was not privy and so will disclose to the solicitor nothing of which he is not already aware."
"We need not linger on Hayes v. Dowding [1996] PNLR 578, a case in which the plaintiffs were held to have impliedly waived their right to legal professional privilege by bringing proceedings even though the proceedings were not against any legal adviser. In reaching that conclusion the judge relied heavily on Australian and United States authority. Neither party before us sought to contend that this case was correctly decided, and we are satisfied that it was not. The authorities on which the judge principally relied do not represent the law of this country, and the decision must be overruled."
"If that is a correct reading of the judge's decision, we consider that he went too far. Fairness is an important part of the reason why a solicitor who is sued cannot be required to respect the confidentiality of his relationship with the client who is suing him; but, save as between the client and the solicitor he is suing, fairness is not the touchstone by which it is determined whether a client has or has not impliedly waived his privilege."
"Where in litigation allegations are made by a party concerning his state of mind (e.g. in entering an agreement) to which legal advice contributed, that party cannot withhold the advice on grounds of privilege, but this is because of implied waiver, rather than because no privilege attached in the first place."
" Hayes v. Downing [1996JPNLR 578 (overruled on another point in Paragon Finance plc v. Freshfields[1999] 1 WLR 1183 , CA); P Matthews & H Malek, Disclosure,(2nd edn,2001), para 9.057. See also paras 5.71-5.100 below."
"Although at the extreme end, the principle was even being applied outside cases involving lawyers: see Hayes v. Dowding [1996] P.N.L.R 578, Jonathan Parker J, overruled by the Court of Appeal in Paragon, and the unsuccessful argument in NRG v. Bacon and Woodrow[1995] 1 All ER 976 , relying on the broader principles appearing from US cases Hearn v. [Rhay] [1975] 68 F.R.D 574; Conkling v. Turner [1989] 883 F2d 431. Australian authority also seems to take a different view to this jurisdiction: Wardrope v. Dunne [1996] 1 Qd R 224."
"...if a communication or document qualifies for legal professional privilege, the privilege is absolute. It cannot be overridden by some supposedly greater public interest. It can be waived by the person, the client, entitled to it and it can be overridden by statute (cf R (Morgan Grenfell & Co Ltd) v. Special Comr of Income Tax[2003] 1 AC 563 ), but it is otherwise absolute. There is no balancing exercise that has to be carried out: see B v. Auckland District Law Society[2003] 2 AC 736 , 756-759, paras 46-54). The Supreme Court of Canada has held that legal professional privilege although of great importance is not absolute and can be set aside if a sufficiently compelling public interest for doing so, such as public safety, can be shown: see Jones v. Smith[1999] 1 SCR 455 . But no other common law jurisdiction has, so far as I am aware, developed the law of privilege in this way. Certainly in this country legal professional privilege, if it is attracted by a particular communication between lawyer and client or attaches be to a particular document, cannot be set aside on the ground that some other higher public interest requires that to be done."
