Business Zone, a licensed fuel retailer, concluded a lease and operation agreement with Engen, a licensed wholesaler, for a service station. In 2010, an addendum was concluded requiring Engen to provide certain premises improvements and access points. When Engen failed to fulfill these obligations, Business Zone complained. Engen responded by alleging Business Zone had made unauthorized alterations and purportedly cancelled the lease on 22 October 2010. Business Zone notified Engen it would refer the matter to arbitration under section 12B of the Petroleum Products Act. Engen continued supplying fuel under an interim arrangement until March 2011, when it terminated supply and purported to cancel the lease a second time based on Business Zone's sale of foreign products. Business Zone sought an interdict from the High Court and lodged a request with the Controller of Petroleum Products for referral to arbitration under section 12B(1), alleging unfair or unreasonable contractual practices by Engen. Both the Controller and the Minister refused the referral, believing that section 12B required an existing valid contract and that the dispute was sub-judice before the High Court. Business Zone successfully reviewed these decisions in the Pretoria High Court, but the Supreme Court of Appeal overturned this on appeal.
