The respondent purchased shares from the appellants under a written agreement dated 25 September 1997. Part of the purchase price was payable immediately, with further tranches payable on the occurrence of future events. In reduction of the first tranche, the respondent issued a cheque for R2 million on 26 November 1997. The cheque was presented for payment and dishonoured. More than three years after the underlying contractual debt became due, but within six years of the dishonoured cheque, the appellants instituted action for provisional sentence on the cheque. The respondent raised several defences, including that the underlying debt had prescribed and therefore the debt arising from the cheque had also prescribed.
