32 Maintenance is the assistance or encouragement, usually by funding, of a party to an action in which the maintainer has no interest. Champerty is a species of maintenance in which the maintainer, in consideration for funding the proceedings, shares in their fruits if they are successful: see e.g. Magic Menu Systems Pty Ltd v AFA Facilitation Pty Ltd (1997) 72 FCR 261, at 267 and the cases there cited.
33 What gives a stranger to litigation a sufficient interest in it to justify maintaining the plaintiff has changed markedly since the common law actions of maintenance and champerty were formulated in the Middle Ages. Indeed, the concept of a sufficient interest in a stranger's litigation has developed throughout the 20th century and is continuing to develop, shaped by changing considerations of public policy and changing ideals as to what is, or is not, conducive to the attainment of justice. As was said by the Full Court in Magic Menu at 267:
"… by the time Martell v Consett Iron Co Ltd [1955] 1 Ch 363 came before Danckwerts J, his Honour was able to observe that support of legal proceedings based upon a bona fide common interest, financial or philosophical, must be permitted if the law itself was not to operate as oppressive. The courts today, in our view, are likely to take an even wider view of what might be acceptable, particularly if procedural safeguards are present or able to be applied."
34 It was the weakness of procedural safeguards to protect the interests of the vulnerable against abuse of process by the powerful which in earlier times was regarded as an essential reason for discouraging the funding of litigation by strangers.
35 In 1963, Lord Denning in In re Trepca Mines Ltd (No 2) [1963] 1 Ch 199, at 219, explained as the policy underlying the prohibition against maintenance and champerty the fear of the common law that the champertous maintainer "might be tempted, for his own personal gain, to influence the damages, to suppress evidence, or even to suborn witnesses" . However, as pointed out by Templeman J in Clairs Keeley v Treacy [2003] WASCA 299, para 60, thirty years later the public policy criteria by which maintenance is judged have been relaxed considerably.
36 In Giles v Thompson [1994] 1 AC 142, Lord Mustill observed at p.153 that as the process of the courts became stronger over time, abuses could more easily be detected and forestalled and litigation more easily determined in accordance with the demands of justice. In other words, the fears of procedural abuse expressed by Lord Denning only thirty years ago have been much allayed by the increased supervision of proceedings by the courts, doubtless due to the adoption of case management principles amongst other reasons.
37 Generally speaking, there are four categories of litigation funding to which the law of maintenance and champerty is now relevant: (1) funding of litigation which is ancillary to assignments of choses in action and analogous transactions; (2) funding of litigation to enforce causes of action assigned by liquidators and bankruptcy trustees; (3) funding of litigation by contingency fee arrangements between parties and their solicitors; (4) funding of litigation not falling into these three categories.
38 Litigation funding in categories 2 and 3 falls to be considered within particular legislative regimes. A bare right of action, as part of the property of a company, may be assigned by a liquidator under s.477(2)(c) Corporations Act 2001 (Cth): see e.g. Re Movitor Pty Ltd (1996) 64 FCR 380; Re William Felton & Co Pty Ltd (1998) 145 FLR 211; Elfic Ltd v Macks [2003] 2 Qd R 125. Solicitors' retainers and contingency fee agreements are regulated by Part 11, Div 3 of the Legal Profession Act 1987 (NSW) and special considerations apply to them in so far as they may be affected by the law of champerty and maintenance: see e.g. Clyne v The New South Wales Bar Association (1960) 104 CLR 186, at 203; Smits v Roach [2004] NSWCA 233, at para.64 ff. The principles of law applicable in categories 2 and 3 do not arise for consideration in the present case.
39 Mr R.G. McHugh, who appears with Mr Lazarus for Mr Barr and TBPL, submits that this case falls into category 1. He says that by the Option Deed Austcorp acquired an equitable interest in the Land and its rights to conduct the Lease Proceedings under the Management Deed are ancillary to that interest. He relies on the well known leading case, Trendtex Trading Corporation v Credit Suisse [1982] AC 679.
40 Mr Einfeld QC, who appears with Mr Dubler for Narui, says that the facts of this case do not fit into category 1 at all. His principal submission is that the Trendtex decision shows that to fall into category 1 a litigation funder must have an interest in the litigation before agreeing to fund it; in the present case, he says, Austcorp acquired an interest in the subject matter of the litigation at the same time as it entered into an agreement to fund the litigation.
