The appellant operated a dental practice from a dwelling house on Stand 1657, Salisbury Township, which he initially leased from Medview Investments (Private) Limited. After the lease expired on 31 May 1989, he became a statutory tenant under the Commercial Premises (Rent) Regulations 1983. The respondent (Canadian Government) owned the adjacent Stand 1656 where its diplomatic mission was located. In late 1989, the respondent applied to the Minister of Local Government, Rural and Urban Development to purchase Stand 1657 for the Decentralised Assistance Programme under CIDA (Canadian International Development Agency). The Minister approved the purchase on 12 December 1989, subject to conditions including that no development could occur without prior consent. The respondent purchased Stand 1657 from Medview on 26 January 1989 (likely 1990 based on transfer date) and transfer was registered on 6 April 1990. The respondent intended to demolish the existing building and construct a three-storey office block for CIDA, consolidating its local offices. On 24 October 1991, the respondent served notice to vacate by 31 December 1991. The appellant refused, arguing the respondent lacked proper development permission. On 10 October 1996, the City of Harare authorized consolidation of Stands 1656 and 1657 into Stand 18540. After continued refusal to vacate, the respondent obtained an eviction order from the High Court on 10 September 1997. The appellant appealed.
