32 In FAI General Insurance v Jarvis (1999) 46 NSWLR 1 Powell JA, after a careful review of the facts and the authorities expressed the view at 18 that the decision of the High Court in Bailey v NSW Medical Defence Union Ltd (1995) 184 CLR 399 and that of the NSW Court of Appeal in McMillan v Mannix (1993) 31 NSWLR 538 seemed to indicate that a failure by an insured to comply with policy provisions requiring prompt notification of occurrences, preservation of property and assistance and co-operation and not making any admissions is - notwithstanding s 54 of the Insurance Contracts Act 1984 (Cth) - sufficient for the purposes of s 6 of the Law Reform (Miscellaneous Provisions) Act 1946 to prevent a court granting to a plaintiff or an intended plaintiff leave to commence proceedings against or leave to amend existing proceeding so as to permit the making of a claim against the relevant insurer pursuant to s 6 of the Act. Powell JA continued at 18-19:
"That this should be so is not entirely surprising, for the provisions of s 6(4) are directed to the questions whether leave to commence, or to amend, such proceeding might be granted, whereas the provisions of s 54 of the Insurance Contracts Act clearly require the determination, at a trial, of the extent of the prejudice which an insurer may have suffered, and the determination of whether or not, in those circumstances, the act or omission of the insured which would other wise have permitted a disclaimer of liability should be permitted to provide a defence, either in whole, or in part, to the claim made by the insured: see, eg, Ferrcom Pty Ltd v Commercial Union Assurance Co of Australia Ltd (1993) 176 CLR 332; Antico v Heath Fielding Australia Pty Ltd (1997) 188 CLR 652. If this be a correct assessment of the effect of the judgment of the High Court in Bailey v NSW Medical Defence Union Ltd then it follows that the provisions of s 54 of the Insurance Contracts Act are irrelevant to any consideration of the question whether or not leave to commence, or to amend, proceedings ought to be given pursuant to the provisions of s 6(4) of the Law Reform (Miscellaneous Provisions) Act. If this be not so, then, by reason of the coming into force of the provisions of s 54 of the Insurance Contracts Act, the proviso to s 6(4) of the Law Reform (Miscellaneous Provisions) Act had long since been deprived of operation, a position for which no-one seems yet to have argued."
33 The plaintiffs contended that FAI v Jarvis was wrongly decided and reserved the right to so argue on appeal. The plaintiffs submitted that he construction of s 6(4) adopted by Powell JA, deprived the second paragraph of s 6(4) of much of its effect. Putting aside the unusual facts of the present case there will be cases where the injured party has made a claim on the insured but the insured or his estate does not send it on to the insurer. The plaintiffs referred to the case where the insured was killed in an accident and the potential plaintiff was seriously injured and died a few days later. They may both be killed in the accident. Assuming the insured cannot be sued, for example, he has disappeared or cannot be found or has died leaving no estate or has become mentally ill, the plaintiffs contended that it would be odd if the effect of s 54 of the Insurance Contracts Act 1984 (Cth) could not be taken into account when considering an application for leave under s 6(4) of the Law Reform (Miscellaneous Provisions) Act 1946. The plaintiffs submitted that if leave were granted under s 6(4) of the 1946 Act that would not stop the insurer agitating those matters in denial or reduction of its liability mentioned in s 54 of the1984 Act. The plaintiffs accepted that on such an approach, prior to leave being granted under s 6(4), the Court would have to be satisfied that the plaintiffs had a good arguable case under s 54.
