Century Discount House (CDH) operated a current account with Zimbabwe Banking Corporation (Zimbank) and enjoyed an unsecured overdraft facility. Zimbank granted CDH overnight accommodation facilities on an informal basis. By letter dated 11 March 2003, Zimbank advised CDH of conditions for such facilities, including the need for security, but did not insist on compliance initially. By November 2003, CDH was having problems regularizing its overnight position. On 5 December 2003, when CDH's account was overdrawn by approximately $12 billion, CDH delivered Grain Marketing Board (GMB) bills with a maturity value of $4 billion to Zimbank as security. On 30 December 2003, Zimbank dishonoured all CDH cheques. On 2 January 2004, the Reserve Bank of Zimbabwe closed CDH's doors. On 5 January 2004, Zimbank liquidated the GMB bills for $3,077,100,273.97. On 22 January 2004, the High Court placed CDH in liquidation at the instance of the Reserve Bank. The liquidator of CDH sought recovery of the full maturity value of the bills, arguing that the liquidation of the bills constituted an undue preference.
