Sentinel Mining Industry Retirement Fund v Waz Props (Pty) Ltd

Waz Props (Pty) Ltd owned properties in Johannesburg and sought rezoning approval. Sentinel Mining Industry Retirement Fund (SMIRF), which was developing the nearby Melrose Arch precinct, objected to the rezoning without merit in order to induce Waz Props to contribute financially to a road upgrade project. The parties concluded a contract under which Waz Props agreed to contribute R115 531.87 to the Park Road Upgrading Project, using one of three payment methods: payment into an attorneys’ trust account, provision of a bank guarantee, or registration of a restrictive condition over the property. Waz Props chose the guarantee option, and ABSA issued a guarantee payable on presentation of a completion certificate. The project was not completed by the contractual deadline of 1 April 2009 but was completed later in 2010. SMIRF’s attorneys nevertheless presented the guarantee and received payment. Waz Props and Werlex Properties sought repayment, arguing that the obligation to pay had lapsed due to non-completion by the agreed date.

The appeal was dismissed with costs, confirming the High Court’s order that the amount paid under the guarantee had to be repaid.

The case is significant for South African contract law in clarifying the use of contractual headings in interpretation, reaffirming the principles governing the implication of tacit terms, and confirming that a resolutive condition may extinguish not only security but the underlying payment obligation. It also illustrates a commercially sensible, contextual approach to contractual interpretation.
