44 In Black v Taylor [1993] 3 NZLR 403, the New Zealand Court of Appeal dismissed an appeal from a declaration that a solicitor should not act further as counsel in certain proceedings on the ground of conflict of interest arising from the solicitor's past receipt of confidential information, but did so on a basis which did not rest on protection of confidential information. Cooke P said [at 406] that the inherent jurisdiction of courts to determine who may be allowed to represent parties to argue cases before them extended to the propriety of a representative appearing in a particular case, which pertained not to the right of practice generally, but to what was needed or may be permitted to ensure in a particular case both justice and the appearance of justice; though the jurisdiction was one to be exercised with circumspection. Richardson J [at 408-409] said that the court had an inherent jurisdiction to control its own processes, which included determining who should be permitted to appear before it as advocates, one aspect of which was the control of a particular proceeding in the court. His Honour described the right to choice of counsel as an important but not an absolute value. After reference to Everingham v Ontario, his Honour held that where it was satisfied that the interests of justice so required, the High Court had an inherent jurisdiction to restrain a barrister from continuing to act as counsel for a particular party in proceedings before the court. His Honour agreed with the approach of the Ontario court, holding that disqualification (in a particular case) would ordinarily be the appropriate remedy where the integrity of the judicial process would be impaired by counsel's adversarial representation of one party against the other [at 42]:
The decision to disqualify is not dependent on any finding of culpable conduct on the lawyer's part. Disqualification is not imposed as a punishment for misconduct. Rather it is a protection for the parties and for the wider interests of justice. The legitimacy of judicial decisions depends in large part on the observance of the standards of procedural justice. Where the integrity of the judicial process is perceived to be at risk from the proposed or continuing representation by counsel on behalf of one party, disqualification is the obvious and in some cases the only effective remedy although considerations of delay, inconvenience and expense arising from a change in representation may be important in determining in particular cases whether the interests of justice truly demand disqualification.
45 In Kooky Garments Limited v Charlton [1994] 1 NZLR 587, Thomas J said that the court had an inherent jurisdiction to supervise the conduct of counsel in court, which included the ability to intervene when counsel or solicitors appeared in a matter in which they had an actual or potential conflict of interest, or where, by reason of their relationship with the client their professional independence might be doubted - because the integrity of the judicial process is undermined if the lawyers do not have the independence and objectivity which they are presumed to have.
46 In Grimwade v Meagher [1995] 1 VR 446, Mandie J held that the court had inherent jurisdiction to ensure the due administration of justice and to protect the integrity of the judicial process, and as a part of that jurisdiction to prevent counsel appearing for a particular party in order that justice not only be done but be seen to be done. His Honour said that the objective test to be applied was whether a fair-minded, reasonably informed member of the public would conclude that the proper administration of justice required that counsel be prevented from acting, giving due weight to the public interest that litigants should not be deprived of their counsel of choice without good cause. In what his Honour described as the "unique, extraordinary and highly exceptional circumstances" of that case, a sufficient real and sensible risk of a lack of objectivity by counsel was found to give rise not only to an undue risk of unfairness or disadvantage to the plaintiff, but also to a substantial concern that a fair trial would not be had, and thus to a concern for the integrity of the judicial process and the due administration of justice.
47 In Yunghanns v Elfic Limited (VSC, 3 July 1998, Gillard J, unreported), Gillard J thought that the authorities established three bases for the grant of a injunction to restrain a solicitor acting against his former client: protection of confidences; breach of fiduciary obligations of trust and integrity; and the administration of justice. With respect to the third basis his Honour said [at 9] that the court had an inherent power to control and deal with members of the legal profession and to ensure that the administration of justice was not brought into disrepute by the conduct of members of the profession.
48 Prince Jefri was a "former client" case. Significantly for present purposes, it concerned accountants, not solicitors, although their Lordships' speeches are expressed in terms which relate to solicitors, and it was accepted that accountants providing litigation support services should be treated for relevant purposes in the same way as a solicitor. As the question of confidential information was at the heart of Prince Jefri, that assumption was an appropriate one in that context. Lord Hope of Craighead considered that the nature of the work which a firm of accountants undertakes in the provision of litigation support services required the court to exercise the same jurisdiction to intervene on behalf of a former client as it exercises in the case of a solicitor, the basis of that jurisdiction being found in the principles which apply to all forms of employment where the relationship between the client and the person with whom he does business is a confidential one [Prince Jefri, 226H-227A]. His Lordship's application to accountants of the jurisdiction relating to solicitors was thus plainly in the context of the protection of confidential information. Lord Millett, with whom Lords Browne-Wilkinson, Clyde and Hutton agreed, said that the duties of an accountant could not be greater than those of a solicitor and may be less, but that insofar as some of the information obtained by KPMG was likely to have attracted litigation privilege though not solicitor/client privilege, it was conceded by KPMG that an accountant providing litigation support services must be treated for present purposes in the same way as a solicitor [Prince Jefri, 234C-D]. Again, this application to accountants of the rules relating to solicitors was plainly in the context of confidential or privileged information.
49 Accountants are not officers of the court, and are not subject to the supervisory jurisdiction of the court to which its officers are subject. The court's inherent supervisory jurisdiction over its officers, including its solicitors was not relevant to Prince Jefri and was not considered in it. In limiting the basis on which a former client could have a solicitor restrained from acting for another to the protection of confidential information, the House of Lords should be taken as having done so to the exclusion of enforcement of any supposed duty of loyalty. However, their Lordships should not be taken as having excluded the court's inherent supervisory jurisdiction over solicitors.
50 Many subsequent authorities have maintained the same view of the supervisory jurisdiction as appears in the cases before Prince Jefri.
51 In McVeigh v Linen House Pty Ltd [1999] 3 VR 394, Batt JA (albeit in a judgment in which Prince Jefri was not cited) said that the authorities established that a court would restrain a solicitor from acting for a litigant, not only in order to prevent disclosure of confidences of a client or former client, but also to ensure that the solicitor's duty of loyalty to the former client was respected notwithstanding termination of the retainer, and to uphold as a matter of public policy the special relationship of solicitor and client.
52 In Oceanic Life Limited v HIH Casualty and General Insurance Limited [1999] NSWSC 272, Austin J said [at 48] that, in addition to fiduciary duties and the duty not to misuse confidential information, a solicitor acting in litigation owed a relevant legal duty to the court as well as an ethical duty:-
[48] The duty to the court arises from the court's concern that it should have the assistance of independent legal representation for the litigating parties: see D A Ipp, "Lawyers' Duties to the Court" (1998) 114 LQR 63, 93. In the realm of conflicts of interest and conflicts of duty, the solicitor's duty to the court may not be much different from his or her fiduciary duties to former and present clients. However, the duty to the court tends to be expressed in such a way as to emphasise the public interest in preserving confidence in the administration of justice, and therefore in the appearance as well as the reality of independence, and the court's practical approach to its supervisory discretions: Fruehauf Finance Corp Pty Ltd v Feez Ruthning [1991] 1 QdR 558; Murray v Macquarie Bank Ltd (1991) 33 FCR 46; Carindale Country Club Estate Pty Ltd v Astill (1993) 42 FCR 307; Macquarie Bank Ltd v Myer [1994] VR 350; Kooky Garments Limited v Charlton [1994] 1 NZLR 587; Watson v Watson (SCNSW, Santow J, unreported, 25 May 1998).
53 In Newman v Phillips Fox [1999] WASC 171, Steytler J granted an injunction restraining Phillips Fox, a law firm, from representing its client corporation in an arbitration, and from disclosing to that corporation certain confidential information which had earlier been provided by the other parties to the arbitration to a firm which had subsequently merged with Phillips Fox. His Honour identified that there had traditionally been three bases for intervention by the court in applications of this kind: the protection of confidential information, restraint of a breach of fiduciary duty in the context of a conflict of interest, and the court's control over the conduct of solicitors as its officers. Of the third, his Honour said:-
[21] As to the third of the bases mentioned above, while it might be so that the basis for the court's intervention has, more recently in England, not been that of a possible perception of impropriety (see, in this respect, what was said by Lightman J in Re A Firm of Solicitors, above [1997] Ch at 9, and again by Lord Millett in [ Prince Jefri ] Bolkiah, above at 224), the jurisdiction to exercise authority over officers of the court as to the propriety of their behaviour has long been recognised both in England and elsewhere. Thus, in Davies v Clough (1937) 8 Sim 262; 59 ER 105 Sir Lancelot Shadwell VC said (at 267; 106-107):-
The cases … appear to afford this general principle, namely, that all courts may exercise an authority over their own officers as to the propriety of their behaviour: for applications have been repeatedly made to restrain solicitors who had acted on one side, from acting on the other, and those applications have failed or succeeded upon their own particular grounds, but never because the court had no jurisdiction.
(See also Re A Solicitor [1987] 131 SJ 1063).
[22] In Australia the courts have, on a number of occasions, shown a willingness to intervene upon this third basis. So, for example, in Yunghanns above at 9, Gillard J affirmed that the court has an inherent power to control and deal with members of the legal profession and to ensure that the administration of justice is not brought into disrepute by the conduct of those members (see also in Re J A Grieve [1861] 1 WWL 197).
54 His Honour referred to observations by Drummond J, in Carindale Country Club Estate Pty Ltd v Astill (1993) 42 FCR 307 [at 311], that there is a public element in the work that a solicitor does as an officer of the court and thus performing an integral part in the administration of justice, and to the observations mentioned above of Austin J in Oceanic Life v HIH Casualty and General, before concluding that there was sufficient foundation for intervention not only on the first but also on the third of the bases mentioned.
55 In Mitchell v Pattern Holdings Pty Ltd [2000] NSWSC 1015, Bergin J refused an application by the defendant for an order that the plaintiff's solicitors cease to act. Her Honour noted observations of Mandie J in Tricontinental Corporation Limited v Holding Redlich (VSC, Mandie J, 22 December 1994), in which his Honour had said that it was a serious matter to prevent a party from retaining the legal representative of its choice, particularly upon the application not of a former client but of an adverse party. Her Honour also referred to Grimwade v Meagher, but thought the circumstances very distinguishable. Nonetheless, her Honour affirmed the availability in an appropriate case of the supervisory jurisdiction [at 34]:-
I am of the view that as an incident of its inherent jurisdiction, this court may decide upon the propriety of a legal practitioner representing a party in a particular case to ensure justice and the appearance of justice. It has been said that such jurisdiction should be exercised with circumspection: Black v Taylor [1993] 3 NZLR 403 per Cooke P at 406; State of Western Australia v Ward and ors (1997) 145 ALR 512 per Hill and Sundberg JJ at 518-519.
56 Prince Jefri was cited, and it does not appear to have been suggested that it excluded the third basis for intervention.
57 In Spincode Pty Ltd v Look Software Pty Ltd (2001) 4 VR 501, the Victorian Court of Appeal dismissed an appeal from the grant of an injunction at the suit of defendants in proceedings, restraining a firm of solicitors from acting or continuing to act for the plaintiff. The principal basis for the decision was that it was a clear case of confidential information relevant to the matters in dispute having been received by the solicitors from the defendants, and that not only had it not been shown that there was no real risk of misuse of that information, but there was a real and sensible possibility of such misuse.
58 However, Brooking JA went further. His Honour concluded that, since the earliest days of attempts to prevent solicitors acting against former clients, one basis of the jurisdiction has been the inherent jurisdiction which the court has over solicitors as its officers [Spincode, 511 [32]]. Brooking JA observed that the supervisory jurisdiction had not been discussed in Prince Jefri [at 514 [37]]:-
In [ Prince Jefri ] Bolkiah the House of Lords disposed of the question whether a basis could be found for restraining a solicitor from acting against a former client other than the protection of confidential information without discussing it at any length. Quite apart from decisions in the United States there is and was a considerable body of authority bearing on that question. I have already drawn attention to some of the many cases which accept that, where a solicitor is an officer of the court, the jurisdiction of the court to restrain the solicitor form acting may be founded not only on the general power which a court exercising equitable jurisdiction has to grant injunctions for the protection of a right but also on the control which a court may exercise over its own officers. Lord Eldon himself was one of the first to speak of this other jurisdiction, and he seems to have been the first to raise the procedural question whether it could be exercised in a cause, in the absence of objection from the solicitor to a defect in the procedure. It may be argued that the existence of the special jurisdiction over officers of the court is not inconsistent with the view that the only basis on which that jurisdiction will be exercised is the existence of a right to prevent the misuse of confidential information. On the other hand, it may be said that the nature and object of the jurisdiction exercised over officers of the court are such as to prevent it being so confined.
[38] There is a good deal of authority for the view that a solicitor, as an officer of the court, may be prevented from acting against a former client even though a likelihood of danger of misuse of confidential information is not shown. …
59 His Honour's examination [at 508-511, [26]-[31]] of Earl Cholmondeley v Lord Clinton (1815) 19 Ves Jun 261; 34 ER 515, shows that it is at best unclear that Lord Eldon's decision was dependant upon the apprehended misuse of confidential information, though at least in one later case Lord Eldon suggested that it was [Bricheno v Thorp (1821) Jac 300, 301; 37 ER 864, 865], and it seems to have been treated as dependant on misuse of confidential information in Rakusen v Ellis. His Honour also referred to Black v Taylor; Grimwade v Meagher; and Holdsworth v M R Anderson and Associates Pty Ltd (VSC, J D Phillips J, 26 August 1994, unreported).
60 Brooking JA concluded that the law in Australia had diverged from that in England; that in Australia the danger of misuse of confidential information was not the sole touchstone for intervention; and that there were two other possible bases for intervention: first, that it was a breach of duty for a solicitor to act against a former client in the same or a closely related matter (such duty being potentially an equitable obligation of "loyalty", or an implied contractual obligation in the retainer; and secondly, that where the conduct of solicitors is so offensive to common notions of fairness and justice they should "as officers of the court" be brought to heel notwithstanding that they have not infringed any legal or equitable right [521-525, [52]-[58]].
