The prescription at the end of section 6(4)
39 The appellant submitted that it was not open to the primary judge to refuse leave on the basis of his satisfaction as to the insurer's entitlement to disclaim, because the "necessary" proceedings to establish that entitlement had not been taken. This submission was based upon the prescriptive words at the end of s6(4) which read:
Leave shall not be granted in any case where the court is satisfied that the insurer is entitled under the terms of the contract of insurance to disclaim liability, and that any proceedings, including arbitration proceedings, necessary to establish that the insurer is so entitled to disclaim, have been taken.
40 If the appellant's submission were correct, it would seem to follow that the Court would be bound to grant leave to proceed against an insurer even in the clearest of cases of the insurer's entitlement to disclaim or avoid liability, simply because the insurer had not initiated proceedings to establish its entitlement to disclaim. There is authority to the contrary (see Andjelkovic v AFG Insurances Ltd (1980) 31 ACTR 17 at 23, Seery v John R Carr & Associates Pty Ltd, Supreme Court unreported, Giles CJ Comm Div, 3 November 1995 at p5).
41 A modified version of this submission was to the effect that leave ought to be given when, notwithstanding that the Court was satisfied on the material before it that the insurer was entitled to disclaim, nevertheless there was an arguable case to the contrary. Reliance was placed upon statements indicating that an arguable case on the indemnity issue should suffice for a grant of leave, just as it would normally suffice in relation to the issue of the plaintiff's case against the insured (see Oswald v Bailey (1987) 11 NSWLR 715 at 734, AFG Insurances Ltd v Andjelkovic (1981) 54 FLR 398 at 400 , Travel Compensation Fund v FAI General Insurance Co Ltd (1999) FCA 1214).
42 These words prescribing when leave must be refused do not appear in the New Zealand legislation upon which s6 seems to have been modelled (see generally Bailey v New South Wales Medical Defence Union Ltd (1995) 184 CLR 399 at 440ff).
43 The uncertain role of the prescription is discussed in earlier case law (see eg Lissenden v Yorkville Nominees Pty Ltd (in Liq) [1984] 3 NSWLR 138 at 142-4, AFG Insurances at 400, Dixon v Royal Insurance Australia Ltd (1998) 90 FCR 390 at 399). Among matters that have been debated were: did the prescription exclusively cover any and if so which field? What is the meaning of "entitled under the terms of the contract of insurance"? What circumstances are encompassed by the second condition in the proscription which speaks of "proceedings … necessary to establish that the insurer is … entitled to disclaim" having been taken?
44 Fortunately, these issues are addressed in extended and authoritative dicta in the High Court in Bailey. McHugh J and Gummow J discussed the meaning of s6, and s6(4) in particular, at 448-450. The other members of the Court (Brennan CJ, Deane J and Dawson J) expressed their agreement with what McHugh and Gummow JJ wrote upon the effect of s6 (see at 415).
45 I shall not set out the lengthy passage from the joint judgment of McHugh J and Gummow J. It is sufficient to observe that their Honours read the prescription as mandatory where it applies, but as not precluding the power to refuse leave in other cases. "Other cases" include cases where there is an issue (at the leave stage) as to the insurer's entitlement to disclaim for non-disclosure, misrepresentation or pursuant to contractual entitlement. The reason why the prescription appears to cover no field exclusively lies in s6(1)'s express recognition that no charge will attach unless and until insurance moneys become payable in respect of the insurer's liability. It is sufficient to quote one paragraph (at 449-50):
The phrase in s6(1), "insurance moneys that … may become payable", is apt to deal with the situation where, whilst the charge has descended, there is as yet no sum which could be identified as presently payable by the insurer to the insured. In such a case, the statutory charge operates, by loose analogy to an agreement for a charge on after-acquired property, upon such moneys as and when they do become payable. However, there will be nothing in respect of which the charge may be enforced if the moneys never become payable by reason of the exercise by the insurer of rights to avoid the contract or of a vitiating factor in its formation. So also is the case of a breach which, pursuant to the terms of the contract (135) or the general law, entitles the insurer to disclaim liability and this state of affairs exists when action is brought by the claimant under s6(4) or, as necessary, leave is sought to commence that action. In all these cases, there were no insurance moneys which were payable when the charge arose and none have become payable. (emphasis added)
