ABSA Bank, as creditor, sued Derryk Page (the principal debtor) for monies owing on an overdraft facility and his son, Jan Hendrik Nel Page, as surety limited to R190 000 plus interest. The trial court (Whitehead AJ) granted judgment for R597 056.57, ordering that the principal debtor and surety were jointly and severally liable for the first R190 000 plus interest, with the principal debtor solely liable for the balance. After judgment, the principal debtor paid R190 000 plus interest pursuant to a garnishee order. The surety contended that this payment discharged his liability. ABSA disagreed and issued a writ against the surety. Competing applications followed to interpret the meaning of the original order and the effect of the payment.
