The respondent's case
36 Senior counsel for the respondents did not rely on the misuse by Mr Collinson - and hence the applicant - of some specific confidential information in the sense in which that concept is defined by authorities such as Ansell Rubber Co Pty Ltd v Allied Rubber Industries Pty Ltd [1967] VR 37, Coco v A N Clark (Engineers) Ltd [1969] RPC 41 at 47 and Deta Nominees Pty Ltd v Viscount Plastic Products Pty Ltd [1979] VR 167. (As to the requirement for specificity as to information said to be confidential see O'Brien v Komesaroff (1982) 150 CLR 310 at 325-326.) Rather it was said that Mr Collinson's acting for the applicant involved a conflict of interest arising from the former's personal experience of Dr Hughes and knowledge of his personal characteristics which amounted to conduct which was unconscionable and which the Court should not tolerate as affecting the administration of justice.
37 Senior counsel referred to a number of authorities which discuss the obligations of legal practitioners to respect the confidence of clients and not "change sides". These are conveniently collected, as senior counsel said, in the decision of Gillard J in the Supreme Court of Victoria in Yunghanns and Ors v Elfic Ltd (unreported, 3 July 1998). In that case, his Honour granted an injunction to restrain the solicitors Corrs Chambers Westgarth from acting on behalf of a client against Mr Peter Yunghanns.
38 Mr Yunghanns had an association with Corrs going back to 1960. He first worked for the firm as an employee solicitor for six years. Then, in Gillard J's words, Mr Yunghanns "turned his hand to commerce" and the firm acted for him in many transactions. The firm had "many opportunities to form opinions as to Mr. Yunghanns' modus operandi in business and legal work". The instant litigation arose out of agreements in 1991 between the Elders Group and Mr Yunghanns which he claimed should be set aside on grounds of unconscionability and economic duress. The firm had acted for both parties in joint ventures between 1984 and 1988. Events in those years were relevant to the circumstances in which the 1991 agreements were made. Further, Corrs had returned some 140 files to Mr Yunghanns but retained a number of documents which he asserted contained confidential information. The firm claimed that the retained documents were not confidential, but did not reveal what was in them.
39 In this setting Gillard J discussed the jurisdiction to restrain former solicitors from acting against a client. His Honour said (at 7):
"…as a general rule it is necessary to identify and establish that there was some confidential information provided (see Bricheno v Thorp (1833) 2 Cr and M 183, 149 ER 725.) But the degree of particularity of the confidential information must depend upon all the circumstances. Often it cannot be identified for fear of disclosure. In considering this factor it must be borne in mind that a solicitor makes notes, forms views and opinions of clients and observes things that the client may have forgotten or overlooked. In some cases the circumstances of the retainer and the nature of the legal work will be sufficient to establish the nature of the confidential information. In this regard the relationship between solicitor and client may be such that the solicitor learns a great deal about his client, his strengths, his weaknesses, his honesty or lack thereof, his reaction to crisis, pressure or tension, his attitude to litigation and settling cases and his tactics. These are factors which I would call the "getting to know you" factors. The overall opinion formed by a solicitor of his client as a result of his contact may in the circumstances amount to confidential information that should not be disclosed or used against the client."
40 Gillard J referred to a number of authorities. In D & J Constructions Pty Ltd v Head (1987) 9 NSWLR 118 at 123, Bryson J noted, inter alia, that
"… the spectacle or the appearance that a lawyer can readily change sides is very subversive of the appearance that justice is being done. The appearance which matters is the appearance presented to a reasonable observer who knows and is prepared to understand the facts…".
41 In McVeigh & Anor v Linen House Pty Ltd & Ors, Victorian Court of Appeal, unreported, 3 September 1999, Batt JA said:
"… authority has established that a court will restrain a solicitor from acting for a litigant not only in order to prevent disclosure of confidence of a client or a former client, but also to ensure that the solicitor's duty of loyalty to the former client is respected, notwithstanding termination of the retainer, and to uphold as a matter of public policy the special relationship of solicitor and client …"
42 In Wan v McDonald (1992) 33 FCR 491 at 512-513, Burchett J said:
"The emphasis in the judgments was placed on the solicitor's duty to safeguard confidential information of his client. But there are at least two other aspects of the problem to which attention has more recently been drawn: a solicitor's duty of loyalty, which cannot be treated as extinguished by the mere termination of the period of this retainer, and the important consideration of public policy which gives a special quality to the relationship of solicitor and client that the law will not generally permit to be stained by the appearance of disloyalty …".
43 While I respectfully accept as good law the authorities which have been mentioned (all of which concerned solicitors rather than counsel), these principles of course have to be applied in the particular context of the present case. The brief summary of the complex facts in Yunghanns is sufficient to show how different it is from the present case. In the abstract, it may be understandable that there is criticism of lawyers who "change sides". But that cannot literally mean that once a lawyer, be it solicitor or barrister, has acted professionally for a particular client, the lawyer is forever after prevented from opposing that client in subsequent litigation.
44 Insofar as reliance is placed on the "getting to know you" principle, a moment's consideration of the way that litigation is conducted in Australia shows that this cannot be accepted too literally, especially in relation to counsel. There are many bodies such as Commonwealth and State government entities, banks, insurers, media companies and many others which are constantly engaged in litigation. Counsel retained to act on behalf of such bodies inevitably acquire information, not confidential information in the strict sense, but experience as to the corporate culture of the clients, their internal policies, the way they deal with litigation, tactics, the personalities of important decision-makers and so forth. I do not accept that general experience of that kind would impose what presumably on the respondent's argument would be lifetime restraints on counsel from acting against such a body. Indeed it is a feature of an independent Bar that counsel might appear one day on behalf of such a body and the next day against it. While perhaps strange to observers from countries where the legal profession is organised differently, this freedom enhances the independence of counsel and their capacity to give objective and sometimes unwelcome advice. The cab rank rule works both ways. The driver is obliged to accept the fare, but the fare does not buy the service of the driver beyond the stipulated journey.
45 Turning to the facts of the present case, I am quite satisfied that in relation to the Westpac litigation there was no confidential information disclosed by Dr Hughes to Mr Collinson which had any relevance or potential relevance to the present proceeding. As for the "getting to know you" principle, this amounts to no more than Mr Collinson meeting with Dr Hughes and forming the impression that he was an intelligent and educated man who, in the course of the mediation showed some originality in proposing settlement ideas. That, to my mind, falls far short of imposing the kind of restriction contended for.
46 As to the conversations in the earlier part of this year, as I have said, I am not satisfied that the first meeting at the tennis club occurred at all, and as to the second conversation, I have found that it was, as Mr Collinson said, no more than an inquiry as to the possibility of his acting. No information relevant to the present proceeding was imparted. Although it is therefore not strictly necessary to say this, I would observe that even if the version advanced by Dr Hughes were correct, what he was conveying to Mr Collinson was not confidential. It was not information conveyed in confidence to a legal practitioner. On the contrary, it was information conveyed to a practitioner whom it was hoped might accept a retainer but did not. The reason that there was no retainer was that Dr Hughes did not proceed with Mr Collinson's obviously proper stipulation that he had to be briefed by solicitors.
47 If it were enough to do what Dr Hughes says to have the effect of preventing counsel from acting against a person, it would be unnecessary to incur the expense of giving special retainers. The litigant could simply telephone counsel and say that there was an interesting case which was very important and involved such‑and‑such issues. Counsel would no doubt say that the person should retain a solicitor to send a brief. The litigant would then go on to another counsel and repeat the process. So it would be possible to effectively immunise an indefinite number of counsel from ever acting on the other side.
48 The motion by notice dated 26 September 2000 will be dismissed. At the request of counsel I shall adjourn the question of costs to a date to be fixed.
