Anthony Simon Bock and Others v Duburoro Investments (Pty) Ltd

The appellants stood as sureties for debts owed by L S Molope Holdings (Pty) Ltd and, in some instances, Dunbush Investments (Pty) Ltd to three banks. Shares in Molope Group Ltd were pledged to the banks as security. Upon default, the banks took over the pledged shares at prices they considered fair and credited the debtors accordingly. The banks later ceded their rights against the sureties to Duburoro Investments (Pty) Ltd, which sued the sureties. The sureties alleged that the banks’ conduct in taking over the shares prejudiced them and released them from liability, alternatively that the credited values were inadequate and the true indebtedness was not established.

The appeals were dismissed and the judgments in favour of Duburoro Investments (Pty) Ltd were upheld.

The case authoritatively rejects the notion of a general prejudice principle in suretyship and clarifies that sureties are released only where prejudice flows from breach of a legal duty. It confirms the constitutionality of parate executie of movables in the creditor’s possession and distinguishes it from unconstitutional statutory self-help. The judgment is a leading authority on security enforcement and suretyship in South African law.
