Guardian National Insurance Company Limited v Springgold Investments (Pty) Ltd

Feedmill Developments (Pty) Ltd, trading as Capital Oils Mills, stored edible palm olein oil in large tanks fitted with steam heating coils. In July 1996, oil in two tanks was contaminated by water from leaking steam pipes. Guardian National Insurance insured the oil under an assets all risks policy, but the policy excluded loss caused directly and solely by contamination. Guardian repudiated the claim on that basis. Feedmill alleged that the leaks were caused by malicious sabotage of the heating coils, which would fall within the policy cover. After Feedmill’s liquidation, Springgold Investments (Pty) Ltd, as cessionary, pursued the claim. The High Court accepted that the pipes had been maliciously damaged. Guardian appealed to the Supreme Court of Appeal, disputing that sabotage had been proven.

The appeal was upheld with costs. The High Court’s order was set aside and replaced with an order dismissing the plaintiff’s claim with costs.

The case is significant for its treatment of insurance policy exclusions, the insured’s onus to prove an exception to an exclusion, and the evaluation of expert evidence. It reinforces that courts must assess expert testimony against the totality of the evidence and probabilities, rather than scientific certainty, and confirms that improbable factual hypotheses will not be accepted without cogent proof.
