On 6 June 2001, the appellant (Steinberg) sold to the respondent (Lazard) his members' interest in a close corporation (Portion 1/8 Erf 11 Sandhurst CC) for R1,365,000. The sale agreement contained a penalty clause requiring each party to complete construction of a dwelling house on their respective properties by 30 June 2002. The penalty for breach was R50,000 per month or part thereof for the period of delay. Both parties failed to meet the deadline. The respondent completed his house on 30 September 2002, while the appellant only completed his house on 15 June 2004. The respondent sued for the penalty calculated from 1 October 2002. After set-off for the first three months and waiver of half the penalty for June 2004, the respondent claimed R1,075,000. The High Court (Willis J) granted judgment for the full amount claimed with interest.
