This case involved a massive cheque 'kiting' or 'cross-firing' fraud perpetrated in 1998 and early 1999 by companies within the 'Weenen group'. The three respondents (all Peens family members) were directors of the Weenen group companies and had signed suretyships for the companies' debts to the appellant bank (Standard Bank). The fraud involved the Weenen group drawing cheques on their accounts with Standard Bank and depositing them with ABSA Bank, and vice versa with Price Busters (another group company), creating false credits through 'round-tripping'. In early January 1999, when Standard Bank discovered the fraud, it instructed that all cheques drawn on Weenen group accounts be dishonoured. This instruction took effect on 6 January 1999, with cheques as far back as 28 December 1998 returned unpaid to ABSA. ABSA objected because the dishonours occurred outside the time limits prescribed by the clearing house rules (Agency Agreement between South African Clearing Banks). On 10 February 1999, the two banks concluded an agreement whereby they rescinded the late dishonours and reinstated the original debits that had been created when the cheques were first honoured. The Weenen companies were placed in liquidation. When Standard Bank sued on the suretyships, the defendants argued that the 10 February agreement created post-liquidation debits, which were unauthorised as the bank's mandate lapsed on liquidation under section 73 of the Bills of Exchange Act 34 of 1964.
