The appellants were proved creditors of Pats Planks CC, a close corporation in liquidation. About a year before liquidation, the corporation executed a general covering cession of its book debts to the appellants in securitatem debiti. The deed of cession included an additional clause stating that the cession would not be implemented unless the account was overdue by 30 days and seven days’ notice of intention to implement had been given. At liquidation, the account was overdue but the seven days’ notice had not been given. The Master of the High Court ruled that, due to the additional clause, the transfer of rights had been suspended and that the book debts formed part of the free residue, not secured assets. The appellants challenged this ruling.
