CSR Ltd & Anor v Maddalena

CSR Ltd and another party appealed to the High Court of Australia against a decision of the Full Federal Court of Australia concerning the interpretation of a workers' compensation insurance policy. The dispute centred on whether the policy covered claims made by employees of a company that had been acquired by CSR Ltd, where those claims related to asbestos-related diseases that manifested after the acquisition but arose from exposure during employment with the predecessor company.

The High Court was required to determine whether the workers' compensation insurance policy, as renewed by CSR Ltd, extended coverage to claims for asbestos-related diseases that manifested after the acquisition of the relevant business, even though the exposure to asbestos occurred prior to the acquisition and during the tenure of the previous owner. A key issue was the proper construction of the policy wording in light of the change in ownership and the nature of latent diseases.

The Court reasoned that the policy, by its terms, covered liabilities incurred by the insured during the period of insurance. It held that a claim for an asbestos-related disease, which is a latent condition, arises when the disease manifests or is diagnosed, not necessarily at the time of exposure. Therefore, if the manifestation or diagnosis occurred during the currency of CSR Ltd's renewed policy, the claim fell within the scope of that policy, irrespective of when the exposure occurred. The Court applied principles of contractual interpretation, focusing on the plain meaning of the policy wording and the nature of the insured risk.

The High Court dismissed the appeal, upholding the decision of the Full Federal Court.
