Agile Capital Holdings (Pty) Ltd (Agile Capital) entered into a purchase and sale agreement with 68 Melville Road Properties (Pty) Ltd (Melville Road) to buy a section in a mixed-use sectional title scheme known as Illovo Point. The purchase price was subject to final adjustment upon completion of the development based on the total base development cost determined by a quantity surveyor, allocated according to each shareholder’s participation quota. If the amounts already paid exceeded the adjusted purchase price, the difference would be refunded; if there was a shortfall, the purchaser had to pay it. After the scheme was completed in August 2020, DHP Quantity Surveyors issued a final total base development cost. Melville Road then claimed shortfall payments from Agile Capital and nine other shareholder-purchasers. Agile Capital resisted payment on several grounds: the deponent lacked authority; the wrong quantity surveyor had made the determination; the schedule was unsworn hearsay; certain costs (storage, insurance) should have been excluded; and additional ‘rolled up’ interest and finance costs caused by delays of a fellow shareholder (Illovo Point Properties) should not be borne proportionally by all shareholders but recovered from the delinquent shareholder. The high court and a full court dismissed all defences and entered judgment for Melville Road. Agile Capital was granted special leave to appeal to the Supreme Court of Appeal on two issues only: whether there was a contractual bar to jurisdiction because the dispute required expert determination, and whether the quantity surveyor’s schedule was inadmissible hearsay.
