The plaintiff, Procon GT Capital (Pty) Ltd, sought summary judgment against the defendants for arrear rental and other charges amounting to R1,108,382.28 in respect of a commercial property in Voortrekker Road, Bellville, which the defendants rented to operate a restaurant. At the time of negotiating the lease, another restaurant operated from the same building by a tenant named Yonas was in direct competition. The plaintiff undertook to evict Yonas as soon as the defendants paid their rental deposit. Based on this undertaking, the defendants signed the lease agreement, paid rent, assumed liability of R430,000 owed by Yonas to the plaintiff, and allowed their R75,000 cash deposit to be set off against Yonas's arrears. Despite the undertaking, it took approximately nine months to evict Yonas, during which period Yonas continued to trade in direct competition with the defendants, causing them to lose approximately 50% of their customer base. The defendants ceased paying full rental and claimed they were entitled to a rental reduction.
