National Vulcan v Transfield; National Vulcan v Connell Wagner; National Vulcan v Coffey Partners International

The appeal concerned the interpretation of an insurance policy and arose from a dispute between National Vulcan (the insurer) and Transfield Pty Limited, Connell Wagner Pty Limited, and Coffey Partners International Pty Limited (the insured parties). The core of the disagreement involved whether the insurer was liable to indemnify the insured parties for damage to property owned by a subcontractor, which occurred during construction works. The matter was heard by Santow and Ipp JJA, and Young CJ in Eq in the Court of Appeal of New South Wales.

The Court of Appeal was required to determine two primary legal issues. Firstly, whether an exclusion clause in the insurance policy, which excluded damage to property owned by the insured, was applicable when the damaged property belonged to a subcontractor and the claim was brought by other parties covered under the same policy. Secondly, the Court had to consider whether the insurers had made a binding election to indemnify the head contractor through their correspondence.

The Court reasoned that the exclusion clause was intended to apply to property directly owned by the insured parties themselves, not to property owned by third parties such as subcontractors, even if those subcontractors were involved in the insured project. The principle applied was that insurance policy exclusions are to be interpreted narrowly and in accordance with their plain meaning, and that the purpose of the exclusion was to prevent the insured from insuring their own property against their own risks. Regarding the election issue, the Court found that the correspondence did not amount to a binding election by the insurers to indemnify the head contractor, as it did not demonstrate a clear and unequivocal choice to abandon one of two inconsistent rights.

The appeal and cross-appeal were dismissed. The appellants were ordered to pay the respondents' costs of the appeal, and Transfield was ordered to pay the cross-respondents' costs of the cross-appeal. These cost orders were deferred for fourteen days to allow parties to make submissions regarding costs, as this aspect had not been fully addressed during the appeal or in written submissions.
