44 As Clyne made plain, there are no fixed categories of professional misconduct. Much depends on whether the conduct falls outside "generally accepted standard[s] of common decency and common fairness". Previous examples of professional misconduct have included wilfully misleading the court (New South Wales Bar Assn v Livesey [1982] 2 NSWLR 231); removing documents in contravention of a court order (Howes v Law Society of the Australian Capital Territory (Supreme Court of ACT, Gallop ACJ, Higgins and Crispin JJ, 23 July 1998, Unreported); permitting conflicts of interest to arise (Law Society of New South Wales v Moulton [1981] 2 NSWLR 736); failing to account for money received (Re Walker; Ex parte Kemp (1887) 3 WN (NSW) 123); misleading a client (Hoshott v Council of the Law Society of New South Wales (Supreme Court of NSW, Meagher, Sheller and Stein JJA, 17 December 1997, Unreported); gross neglect and delay (Legal Practitioners Conduct Board v Hay [2001] SASC 322; (2001) 83 SASR 454); failing to adequately supervise an unqualified clerk (Law Society of New South Wales v Foreman (1991) 24 NSWLR 238); breaching an undertaking given to another lawyer (Wade v Licardy (1993) 33 NSWLR 1); and, in certain situations, criminal and/or personal misconduct (Ziems v Prothonotary of the Supreme Court of New South Wales (1957) 97 CLR 279).
45 The present appeal must be determined having regard to section 208Q of the LPA 1987, which provides that deliberate charging of grossly excessive costs constitutes professional misconduct (see also Re Veron; Ex parte Law Society of New South Wales (1966) 84 WN (Pt 1) NSW 136 at 144 (and authorities cited therein); Evatt v Bar Association of New South Wales (1968) 117 CLR 177; Veghelyi v The Law Society of New South Wales (NSW Court of Appeal, Kirby P, Mahoney and Priestley JJA, 6 October 1995, Unreported)). Mahoney J in Veghelyi explained why that is so (at 9 - 11):
"The Court has traditionally and for centuries exercised control over 'the excessive fees and other unnecessary demands' made by solicitors of the court: see, eg, Holdsworth's History of English Law, 2nd ed, Vol 6, 434; Vol 12, 56-62. Clients are, or may frequently be, in a vulnerable position vis-a-vis their solicitors; the presumption of undue influence is, I think, based at least in part upon the fact that when making decisions clients ordinarily or at least frequently place trust in their solicitors. They ordinarily are not in a position to know without investigation what work must be done and what charges are fair and reasonable; they ordinarily assume that the solicitor will make only such charges.
Solicitors are, on the other hand, informed, or in a position to inform themselves, of what work may be required and what are fair and reasonable charges. They are, in that sense, in a position of advantage and trust is placed in them. Clients are entitled to be protected against the abuse of such an advantage. It is, I am inclined to think, the fact that that advantage has been misused which may, in a particular case, warrant what the solicitor does being categorised as professional misconduct."
46 His Honour went on to discuss the circumstances in which charges may be considered "excessive". His Honour explained (at 9 - 12):
"A solicitor's entitlement to remuneration is conventionally stated in terms of what is fair and reasonable in the circumstances: see Re Stuart; Ex parte Cathcart (1893) 2 QB 201; Clare v Joseph (1907) 2 KB 369 at 372, 376, 378; New South Wales Crime Commission v Fleming (1991) 24 NSWLR 116 at 121-123, 127-128, 142-144. Where charges are so far beyond that as to be grossly disproportionate, professional misconduct may be involved. This is so in England and in Australia; a somewhat similar principle appears to have been adopted in the United States of America notwithstanding the different attitude taken in that country to lawyers' costs: see generally American Bar Association Model Rules of Professional Conduct, in particular R1.5 which provides 'a lawyer's fee shall be reasonable ...' and R8.4 which states that violation (or attempted violation) of any rule constitutes "professional misconduct". For a discussion of these rules, see G Hazard, Jr and WW Hodes, The Law of Lawyering, 2nd ed, 1990, Vol 1, and S Gillers and RD Simon, Jr, Regulation of Lawyers: Statutes and Standards, 1991. A principle stated in such terms is, of course, inherently indeterminative. But I do not think that it is possible to formulate the principle in terms which are more specific.
The determination of what in a particular case is fair and reasonable will require consideration of various factors. S208G of the Legal Profession Act 1987 provides:
'208G. In assessing what is a fair and reasonable amount of costs, a costs assessor may have regard to any or all of the following matters:
(a) the skill, labour and responsibility displayed on the part of the barrister or solicitor responsible for the matter;
(b) the complexity, novelty or difficulty of the matter;
