Köster v Norval

In February 2004, Archibald Norval (respondent) entered into two written agreements with Ralph Werner Köster (appellant) to dispose of his interest in Flexivest 6 (Pty) Ltd for R8.5 million. The first agreement involved the sale of all issued shares in Flexivest for R6.5 million. The second agreement involved the sale of game listed in an annexure for R2 million, with payment due five years after the agreement date without interest. The respondent was not the owner of the game; it belonged to Flexivest. The share sale was completed, but after five years elapsed, the appellant refused to pay the R2 million purchase price for the game. The Western Cape Division of the High Court (Van Staden AJ) granted judgment in favour of the respondent for R2 million plus mora interest and costs. The appellant appealed to the Supreme Court of Appeal.

• Whether a seller who is not the owner of the thing sold is obliged to transfer ownership to the purchaser
• Whether delivery of vacua possessio (undisturbed possession) coupled with warranty against eviction satisfies the seller's obligations under South African law
• Whether tacit or implied terms can be imported into a contract requiring the seller to be the owner and to transfer ownership when this contradicts the express terms and principles of the law of sale
• Whether the appellant was liable to pay the purchase price for the game despite the respondent not being the owner

The appeal was dismissed with costs.

In South African law, it is not a requirement for a valid contract of sale that the seller must be the owner of the thing sold. The seller's obligations are to deliver vacua possessio (undisturbed possession) and to warrant against eviction. The seller is not obliged to transfer ownership to the purchaser. The seller must divest himself of all proprietary rights in the thing sold in favour of the purchaser and warrant that no person with a better right will lawfully deprive the purchaser of the thing sold. No tacit or implied term can be imported into a contract that contradicts the express terms of the contract or established principles of law. Where delivery of possession has occurred in accordance with the contract and there has been no eviction, the purchaser remains liable to pay the purchase price even if the seller was not the owner of the goods sold.

The court noted that the admissions made by the respondent in response to requests for further particulars (admitting that the plaintiff was capable of transferring ownership and that delivery would be effected with intention to transfer ownership) constituted errors of law and the respondent was not bound by them. The court observed that the sole reason for the separate agreement in respect of the game was to accommodate the appellant's request for a five-year interest-free extension of payment, in return for which the respondent obtained the right to occupy the house and farmyard on the farm for five years. The court characterized the appellant's defence as "contrived and disingenuous" given the undisputed facts that there was an agreement, the game was delivered, and no payment was made.

This case reaffirms the long-established South African law principle that a seller need not be the owner of goods sold and is not obliged to transfer ownership. The seller's obligations are limited to delivering undisturbed possession (vacua possessio) and warranting against eviction. The case provides clarity on the distinction between implied terms (rules of law applicable unless validly excluded) and tacit terms (found by necessary implication in the unexpressed intention of parties), and confirms that neither can be imported to contradict express contractual terms or established legal principles. It serves as an important reminder of the fundamental principles of the South African law of sale derived from Roman-Dutch law.
