Mutual & Federal Insurance Co Ltd v Da Costa

The respondent, a Pretoria businessman, insured several motor vehicles with the appellant insurer. In January 1996 he acquired a Mercedes Benz vehicle, which he believed to be a 1991 Mercedes Benz 230E, and it was added to the insurance policy under that description. The vehicle was later damaged while in the possession of the respondent’s partner and was written off as uneconomical to repair. The insurer repudiated the claim, alleging that the vehicle was a built-up vehicle consisting of parts from different model years and that the description constituted a material misrepresentation or non-disclosure. The magistrate’s court upheld the respondent’s claim for indemnification, and the High Court dismissed the insurer’s appeal. The insurer then appealed to the Supreme Court of Appeal.

The appeal was dismissed with costs.

The case clarifies South African insurance law on material misrepresentation, confirming that insurers bear the onus of proving materiality and cannot rely on assumed materiality without evidence. It also reinforces strict pleading requirements in insurance disputes and affirms the continued application of the robust approach to quantifying damages where exact proof is impractical.
