The plaintiff (BP Zimbabwe) entered into a written lease agreement with Solta Trading (Pvt) Ltd in September 1998 for stand number 10232 Highfield Township (Machipisa Service Station) until 31 July 2024. BP advanced a loan to Solta to purchase the premises, and the loan amount constituted prepaid rent for the entire 26-year lease period. In 1998, BP took occupation and built a filling station. In 2006, BP exercised its right to sublet the premises back to Solta under a written sub-lease agreement running from 1 January 2006 to 31 December 2006, with monthly rent of US$4,500. The sub-lease agreement prohibited Solta from further subletting without BP's prior written consent. After the sub-lease expired on 31 December 2006, Solta remained in occupation and became a statutory tenant. In February 2009, Solta sublet the premises to the defendant (Cedar Petroleum) without obtaining BP's prior written consent. The defendant took occupation and BP instituted ejectment proceedings. The parties agreed to proceed by way of special case to determine the legal issues.
