Shoprite Checkers (Pty) Ltd sold a business as a going concern to Bumpers Schwarmas CC in terms of a written sale agreement. After the conclusion of the agreement, the respondents sought rectification of the contract, alleging that it failed to record a common intention that Shoprite was obliged to procure a lease for the purchaser on terms identical to a previous lease (the Palmer lease), save for duration and rental. Evidence was led concerning pre-contractual discussions with the landlord’s representatives, Hirschfield and Fine, who testified that any new lease would necessarily include a ‘development clause’ allowing the landlord to terminate the lease on notice for redevelopment. The court a quo accepted the respondents’ version and granted rectification. Shoprite appealed to the Supreme Court of Appeal.
