Samancor Limited v Mutual & Federal Insurance Company Limited and Others

An emergency pump supplying oil to an alternator failed, causing damage to the alternator. The alternator was insured under two indemnity insurance policies: a works policy underwritten by several insurers (the respondents) and an assets policy underwritten by Westchester Insurance Company. Westchester fully indemnified Samancor Limited (the appellant) for the loss under the assets policy. Samancor, acting through Westchester by way of subrogation, then sued the respondents under the works policy to recover the same loss. The respondents raised a special plea contending that because Samancor had already been fully indemnified, no further claim lay, and that Westchester’s only possible remedy was a contribution claim against co-insurers, not a subrogated claim in the name of the insured.

The appeal was dismissed with costs, including the costs of two counsel. The respondents’ special plea was upheld, and the appellant’s subrogated claim failed.

The case is a leading South African authority on the distinction between subrogation and contribution in insurance law. It clarifies that where multiple insurers provide indemnity for the same loss with equal and co-ordinate obligations, payment by one insurer discharges the insured’s claim against the others, leaving only a contribution remedy between insurers. The judgment affirms that precedence and excess clauses regulate contribution rights but do not convert co-insurers into primary and secondary debtors.
