Australasian Medical Insurance Limited v CGU Insurance Limited

The matter before the Court was an action by Australasian Medical Insurance Limited against CGU Insurance Limited, seeking a declaration that CGU had breached its contract of insurance by failing to indemnify Australasian Medical Insurance. The dispute arose from a claim made by Australasian Medical Insurance under its policy with CGU, which sought to recover losses allegedly due to double insurance, where CGU had issued a policy to the same insured under the same circumstances as Australasian Medical Insurance. The Federal Court of Australia was tasked with determining whether there was double insurance and whether the exclusion of cover was avoided by section 45 of the Insurance Contracts Act 1984 (Cth).

The central legal issues were whether the two insurance policies covered the same risk and, if so, whether section 45 of the Insurance Contracts Act 1984 (Cth) avoided the exclusion of cover. Additionally, the Court had to determine whether the identity of the parties to CGU's policy was relevant to the dispute and whether estoppel by convention applied. The Court held that there was no double insurance as the policies did not cover the same risk and that the exclusion of cover was not avoided by section 45 of the Insurance Contracts Act 1984 (Cth). The Court further found that the identity of the parties to CGU's policy was not relevant and that estoppel by convention did not apply.

The Court dismissed the proceeding, ordered Australasian Medical Insurance to pay CGU's costs of and incidental to the proceeding, including any reserved costs, to be assessed on the standard basis. The Court also granted liberty to apply in relation to the question of costs, should it be submitted some alternative order is appropriate. This decision underscores the importance of understanding the scope of insurance policies and the application of statutory provisions in insurance disputes.
