The appellant, an agricultural co‑operative operating in Swellendam, contracted with the respondent, a manufacturer of steel structures, for the design and erection of a complex of steel silos intended exclusively for the storage of canola seed. At the time of contracting in 1995, canola was a new crop in South Africa and neither party had knowledge of its storage requirements, particularly in Swellendam’s warm and humid climate. After the silos were erected, large quantities of canola from the 1995/1996 harvest deteriorated due to heat and moisture build‑up, resulting in substantial income loss. Structural problems also arose: most silos leaked, several were fitted with eccentric inlets, and many silos buckled (swigting) during normal use. The appellant claimed damages for (a) consequential loss arising from the spoiled canola and (b) direct loss consisting of repair, reinforcement, and modification costs. The claims were based on an alleged breach of an express contractual warranty and, alternatively, the implied warranty against latent defects.
The appeal was upheld. The order of the court a quo was replaced with an order declaring the respondent liable for the costs of emptying and repairing silo four, modifying the inlets of specified silos, reinforcing all silos, and related engineering fees, together with interest. The respondent was ordered to pay 60% of the appellant’s costs in the court a quo (including expert fees), 60% of the record costs on appeal, and one‑third of the appellant’s remaining appeal costs. Claims for consequential damages arising from the spoiled canola were dismissed.
The case is significant for South African contract and sale law because it clarifies the interpretation of express warranties in their factual context and confirms that neither express nor implied warranties against latent defects automatically extend to consequential loss unless such liability is intended by the parties. It also illustrates the distinction between liability for direct (structural) damages and exclusion of liability for consequential damages, as well as the evidentiary approach to latent defects in complex commercial construction disputes.
