23 Irrespective of whether the rule espoused by Deane J applies to this case, the general rules relating to the statute barring of actions for damages arising out of professional negligence are well-settled. The Deane J rule needs to be seen in the context of these general rules, which I set out below.
24 A cause of action is not complete until the plaintiff suffers actual (and not contingent or prospective) loss or damage: Hawkins v Clayton at 561 to 562, 588; 600 to 601; Wardley Australia Limited v Western Australia (1992) 175 CLR 514 at 530 to 531; Scarcella v Lettice [2000] NSWCA 289.
25 For a plaintiff's cause of action to be complete, the actual damage must be "measurable" (Wardley at 531), or "beyond what can be regarded as negligible" (per Handley JA in Scarcella).
26 A cause of action accrues when it is complete and, ordinarily, a cause of action for negligence first accrues when the plaintiff first suffers damage caused by the defendant's breach of duty: Hawkins v Clayton at 561 per Brennan J and 588 per Deane J; Pirelli General Cable Works Limited v Oscar Faber & Partners (a firm) [1983] 2 AC 1; Sampson v Zucker (NSW Court of Appeal, unreported, 11 December 1996); Scarcella.
27 An action for damages against a solicitor, where the solicitor negligently fails to commence proceedings for a claim for personal injury within the statutory period, is a claim for damages for loss of a chance of recovering damages for those personal injuries: Johnson v Perez (1988) 166 CLR 351; Nikolaou v Papasavas, Phillips & Company (1989) 166 CLR 394 at 402 to 404. In such a case, the plaintiff's loss crystallises when the action becomes statute barred (cf Johnson v Perez at 366 to 367).
28 Generally, where, through the negligence of solicitors, a client's cause of action becomes statute barred, the client's right of action in negligence against those solicitors accrues at the time the action becomes statute barred, and damages are to be assessed at that time: Nikolaou; Scarcella; Sampson v Zucker; Registrar-General v Cleaver (1996) 41 NSWLR 713 per Clarke JA at 719; Hetherington v Mirvac Pty Limited (1999) Aust Torts Reports 81- 514; Crisp v Blake (1992) Aust Torts Reports 81-158; Toomey v WALS (1999) NSWSC 560; Wilson v Rigg [2000] NSWSC 16; Di Sante v Camando Nominees Pty Limited [2000] VSC 211; Doundoulakis v Antony Sdrinis & Co [1989] VR 781.
29 There is no "general overriding qualification" to the effect that a limitation period does not begin to run "until the stage is reached when the plaintiff discovers, or could on any reasonable inquiry have discovered, that the loss has been sustained": Wardley at 540 per Deane J; Hawkins v Clayton at 561 to 562 per Brennan J, at 587 to 588 per Deane J, at 599 to 601 per Gaudron J; Sampson v Zucker; Scarcella.
