Harvey Trinder (NSW) Pty Ltd v Government Insurance Office of NSW

Harvey Trinder (NSW) Pty Ltd (the appellant) appealed to the High Court of Australia from a decision of the Supreme Court of New South Wales concerning a claim for indemnity under a policy of insurance issued by the Government Insurance Office of New South Wales (the respondent). The dispute arose from a fire that destroyed the appellant's premises and stock, and the respondent denied liability under the policy, alleging that the appellant had breached a condition precedent to the policy's currency.

The central legal issue before the High Court was whether the appellant had complied with a condition precedent requiring it to disclose to the respondent all material facts relating to the risk to be insured. Specifically, the court had to determine if the appellant had failed to disclose that its premises were subject to a mortgage, and if so, whether this non-disclosure rendered the policy void ab initio.

The High Court, in a joint judgment, held that the appellant had indeed failed to disclose the existence of the mortgage, which was a material fact that a reasonable insurer would have taken into account when assessing the risk and setting the premium. The court applied the principle that an insured has a duty to disclose all material facts known to them, even if not specifically asked, and that a breach of this duty can entitle the insurer to avoid the policy. The court found that the non-disclosure was not a mere oversight but a failure to meet the contractual obligation of disclosure, thereby vitiating the policy from its inception.

The appeal was dismissed, and the judgment of the Supreme Court of New South Wales was affirmed.
