The court confirmed the principle from Froman v Robertson 1971 (1) SA 115 (A) that a cheque must be founded upon justa causa debendi to be valid and enforceable, and a claim for enforcement will be defeated if the requisite justa causa was lacking or has failed (for example, where the underlying contract was voidable, illegal, or there has been failure to perform). However, the court distinguished between defences based on lack of causa (which would defeat the claim on the cheque) and defences based on prescription of the underlying debt (which do not affect the independent prescription period applicable to the cheque itself).
