On 2 July 2002, Mia (the appellant) entered into a written agreement to purchase immovable property in Sandton from Verimark Holdings (Pty) Ltd (the respondent) for R13.5 million. The purchase price was to be secured by providing a suitable, unconditional and irrevocable guarantee within seven days of conclusion of the agreement. The contract contained a suspensive condition that the guarantee had to be obtained within seven days, failing which the agreement would be of no force and effect. The guarantee was not provided by 10 July 2002 and the agreement lapsed. Verimark did not allege that Mia had designedly prevented fulfilment of the condition. Nonetheless, Verimark sued Mia for damages: (1) R13,160 for costs of drafting, negotiating and signing the agreement (later conceded); and (2) R2,248,964.49 for various additional costs Verimark allegedly incurred because it could not relocate from its office and warehouse premises to new consolidated premises. At the time, Verimark was planning to sell the office property and terminate its warehouse lease to save costs by consolidating into new premises. Verimark claimed it would have moved to new premises by 1 November 2002 if the sale had proceeded, but instead had to remain in the old premises and continue leasing the warehouse until later dates in 2003.
