Engen Petroleum Limited, as lessee of certain premises and sub-lessor to Rissik Street One Stop CC, entered into a fixed-term operating lease with the first respondent for the operation of a fuel service station. The lease expired by effluxion of time on 31 October 2018 after renewal negotiations failed, primarily due to Engen’s demand for a R3 million payment as a condition for renewal. Engen gave notice that it would not renew the lease. The respondents sought to sell the service station business and proposed purchasers to Engen, but Engen refused consent. Prior to expiry, the second respondent referred an alleged unfair or unreasonable contractual practice to the Controller of Petroleum Products under s 12B of the Petroleum Products Act 120 of 1977. After expiry of the lease, the respondents remained in occupation. Engen instituted eviction proceedings. The High Court stayed the eviction and interdicted Engen pending the outcome of the s 12B arbitration. Engen appealed to the Supreme Court of Appeal.
