Eldacc (Pty) Ltd leased commercial property to Rennies Distribution Services (Pty) Ltd for ten years. The lease contained clause 35, an option to purchase the property, expressly framed as a stipulatio alteri in favour of Rennies or its nominee, being any subsidiary of the Bidvest Group Ltd in existence at the date of signature. Rennies orally nominated Bidvest Properties (Pty) Ltd as nominee. Within the stipulated period, Bidvest delivered written notice exercising the option. Eldacc refused to proceed with the sale and purported to cancel, arguing that the nomination and acceptance constituted a variation of the lease requiring compliance with a non-variation clause. Bidvest sought specific performance in the South Gauteng High Court, which was granted. Eldacc appealed to the Supreme Court of Appeal.
