MARLAINE MAY AGNES CLAYTON v MUTUAL COMMUNITY GENERAL INSURANCE PTY LTD No. SCGRG 94/1259 Judgment No. 5080 Number of Pages - 5 Insurance - Fire Insurance (1995) 8 ANZ Insurance Cases 61-263 (1995) 64 SASR 353

The case of Marlaine May Agnes Clayton v Mutual Community General Insurance Pty Ltd was heard by the Supreme Court of South Australia. The plaintiff, Marlaine May Agnes Clayton, sought damages from the defendant, Mutual Community General Insurance Pty Ltd, for fire damage to a house that was insured under a policy with the defendant. The house was jointly owned by the plaintiff and her estranged husband, who committed suicide by igniting petrol fumes in a car in the carport, causing damage to the car and the carport and subsequently spreading to the house.

The primary legal issues the court had to address were whether the damage to the house was caused by a deliberate or intentional act and whether the damage arose from an unlawful act. The court examined the policy exclusions which covered loss or damage caused by deliberate or intentional acts and loss, damage, or liability arising from any unlawful act or omission by the insured or any other person insured by the policy.

The court reasoned that the exclusion for deliberate or intentional acts applied only where the insured intended to cause the damage. In this case, the deceased did not intend to damage the house; thus, the exclusion did not apply. However, the court found that the damage to the house arose from the unlawful act of damaging the jointly owned car, which the deceased did not have lawful authority to do. The court concluded that the insurance policy exclusion for damage arising from an unlawful act applied, and therefore, the defendant was not liable for the damages.

The appeal was dismissed, and the decision of the District Court was upheld. The Full Court of the Supreme Court of South Australia, comprising King CJ, Duggan, and Nyland JJ, unanimously agreed on the dismissal of the appeal.
