Anchorage Marine Underwriting & Anor v Hansen Dev

Anchorage Marine Underwriting Pty Ltd and another party (the appellants) appealed to the High Court of Australia against a decision of the Full Federal Court concerning the interpretation of a marine insurance policy. The dispute arose from a claim made by Mr Hansen (the respondent) under a policy of marine insurance for damage sustained to his vessel, the 'Sea Eagle'. The appellants, as the insurers, denied liability on the grounds that the damage was caused by the respondent's wilful misconduct, which was excluded under the policy.

The High Court was required to determine whether the damage to the 'Sea Eagle' was caused by the wilful misconduct of the respondent, Mr Hansen, within the meaning of the exclusion clause in the marine insurance policy. This involved considering the nature of wilful misconduct in the context of insurance law and the evidentiary burden to establish such a defence. The court also had to assess whether the findings of fact made by the lower courts were sufficient to support the conclusion of wilful misconduct.

Gummow and Callinan JJ, in their joint judgment, affirmed the principles governing the interpretation of exclusion clauses in insurance contracts, emphasising that they must be construed strictly against the insurer. They noted that wilful misconduct requires a deliberate act or omission with knowledge of the probable consequences, or a reckless disregard for those consequences. The court found that the evidence did not establish that Mr Hansen had acted with the requisite wilful misconduct to bring the damage within the exclusion clause. The appeal was accordingly dismissed.
