Guardian National Insurance Company Limited v Searle NO

A loss of support claim was brought on behalf of Samantha Searle, whose parents died in a motor vehicle accident in December 1989. The claim was instituted against Guardian National Insurance Company under motor vehicle insurance legislation. By the time the matter came to trial in the High Court, liability was no longer in issue and only the quantum of damages remained unresolved. The parties’ actuaries agreed that a deduction had to be made for the accelerated benefit Samantha received through her inheritance, but they differed on the method of calculating that deduction, including whether the inheritance should be escalated for inflation and whether benefits already received from the trust should be taken into account. The trial court made certain rulings on these actuarial calculation principles but did not finally determine the amount of damages. Before the trial was concluded and before a final damages award was made, the defendant sought and obtained leave to appeal against those rulings.

The appeal was struck off the roll on the basis that the rulings appealed against were not appealable. The appellant (defendant) was ordered to pay the wasted costs of the appeal.

The case is significant for reaffirming and applying the South African law principles governing appealability, particularly the strong policy against piecemeal appeals. It clarifies that interlocutory rulings on evidential or methodological issues, such as actuarial calculations in damages claims, are generally not appealable unless they finally determine rights or dispose of a substantial portion of the relief claimed. The judgment reinforces the Zweni criteria as the central test for appealability in South African appellate practice.
