On 22 May 1997, Loriza Brahman (a Brahman stud breeding operation owned by Tommiesrus (Pty) Ltd) held a production auction of Brahman stud heifers on the farm 'Sandbult' near Nietverdiend in the North-West Province. The second appellant, Naudé, was the manager of the Loriza stud herd. The respondent, Dippenaar, a chartered accountant and part-time farmer from Centurion, attended the auction intending to purchase several heifers to establish his own Brahman stud. About 20 minutes before the auction commenced, Dippenaar met with Naudé at the auction pens to identify suitable animals. Accompanied by Maurice Meyer (Naudé's brother-in-law) and Dr Archie Kritzinger (a veterinarian and Loriza's herd vet), they entered a pen containing approximately 25 Brahman heifers to view and mark animals in the catalogue. The pen was about 30 meters long, with a rear section approximately 20 meters wide and a narrower front section about 10-15 meters wide. Several auction attendees were in the pen viewing the heifers. Dippenaar testified that he and Naudé were looking at the catalogue, and he did not see the heifers and was not aware of their presence in the pen. Suddenly, everyone heard a snorting sound. Naudé looked up and saw one of the heifers, Alicia, charging toward them. He shouted a warning. Dr Kritzinger waved his catalogue to make the heifer change direction. The group scattered. The heifer swerved toward the pen fence, ran into it, turned around and ran back with her head down toward the other heifers still standing together. In the process, she knocked Dippenaar over with her head or shoulder. She then rejoined the herd. As a result of the collision, the tibia and fibula of Dippenaar's right leg were broken just above the ankle joint. Dippenaar sued Loriza with the actio de pauperie and, alternatively, sued Naudé with the actio legis Aquiliae for compensation for his damages. During the trial, Dippenaar did not attempt to prove or pursue his claim against Naudé.
