Antony Louis Mostert NO v Old Mutual Life Assurance Company (South Africa) Limited

The appellant, Antony Louis Mostert NO, acting in his capacity as curator of the CAF Pension Fund, successfully appealed against an earlier judgment and obtained an order from the Supreme Court of Appeal awarding substantial damages against the respondent, Old Mutual Life Assurance Company (South Africa) Limited. After the appeal judgment was delivered, disputes arose between the parties regarding the interpretation and application of paragraph 2.3 of the order, specifically how amounts recovered by the appellant on behalf of the pension fund should be deducted from the awarded sums and how interest should be adjusted. The respondent paid an amount it calculated as the balance due, which the appellant disputed. Both parties brought further applications seeking amendments or clarifications of the appeal order.

The appellant’s application for clarification was allowed with costs, including the costs of two counsel. Paragraph 2.3 of the original appeal order was amended to provide expressly that recoveries are to be deducted first from interest and then from capital, with reference to the agreed schedule of recoveries. The respondent’s counter-application was dismissed with costs (including two counsel), except for a minor amendment to paragraph 3 of the original order, which was granted by consent.

The decision is significant for South African appellate practice and the law of damages because it clarifies the narrow circumstances under which a final appellate order may be clarified after delivery. It provides authoritative guidance on interpreting and giving effect to ambiguous damages orders and underscores that the purpose of damages is restitutive rather than punitive. The judgment also illustrates the limits of raising new factual or legal issues after trial and appeal.
