The respondent, a businessman, suffered severe physical and psychological harm following a failed intubation by the appellant, an anaesthetist, prior to a scheduled back operation in May 2000. The appellant admitted liability for damages arising from the intubation. The respondent alleged that as a result of his prolonged hospitalisation and subsequent depression, he was unable to manage his business interests effectively, particularly Koos Nel Auto (Pty) Ltd, leading to reduced profits. Initially the respondent was the sole shareholder of the company, but on 1 April 2001 he sold his shares and loan account to the Koos Nel Trust for estate planning purposes. He claimed damages for loss of income and earning capacity, future medical expenses, and general damages.
