Cook v Sirius International Insurance Corporation Australian Branch

In *Cook v Sirius International Insurance Corporation Australian Branch*, the New South Wales Court of Appeal considered an appeal from a primary judge's decision concerning a property insurance claim following fires at hotel premises. The insurers alleged that the fires were deliberately lit, while the insured argued otherwise. The appeal concerned the primary judge's findings of fact and the application of legal principles to those findings.

The central legal issues before the Court of Appeal were whether the primary judge had erred in finding that the fires were deliberately lit, and consequently, whether the insured was entitled to indemnity under the property insurance policy. This involved a review of the evidence presented, including the insurers' reliance on a circumstantial case suggesting arson, and the insured's counterarguments regarding plausible innocent explanations for the fires. The Court was required to determine the relevance of financial motive, the insured's means and opportunity to commit arson, and the interpretation of evidence such as passive infrared sensor data, the timing of events, the layout of the premises, and the plausibility of intruders.

The Court of Appeal affirmed the primary judge's findings, holding that the circumstantial evidence, when viewed holistically, strongly pointed towards arson. The Court applied established principles regarding the assessment of circumstantial cases in civil proceedings, emphasizing that while innocent hypotheses must be considered, they must also be plausible and consistent with the evidence. The Court found that the primary judge had correctly weighed the evidence, including the financial position of the insured and the lack of credible evidence supporting an external cause for the fires. The Court also noted its obligation to conduct a "real review" of the evidence and reasons when the primary judgment was not solely dependent on credibility findings, which it undertook in this instance.

The appeal was dismissed with costs.
