Dr David Griesel, a game farmer, sold a bull buffalo to Mr Piet Haasbroek for R1 million plus VAT. The sale was concluded at Dr Griesel’s farm when the buffalo was offloaded. An express term of the sale was that Mr Haasbroek would assume the risk of death or injury to the buffalo arising from a high‑risk veterinary operation (darting and sedation) necessary to draw blood for disease testing to obtain a transport permit. During the operation on 27 October 2009, the buffalo was successfully darted but was not immediately followed. It later died due to suffocation caused by regurgitation while sedated. Dr Griesel sued Mr Haasbroek for the purchase price. The trial court and full court dismissed the claim, but Dr Griesel appealed to the Supreme Court of Appeal.
