Delta Beverages (Private) Limited (appellant), a Zimbabwean company, and Blakey Investments (Private) Limited (respondent), a South African company, had been in a business relationship for several years, with the respondent supplying the appellant with plastic products. On 16 March 2018, Cynthia Malaba, the appellant's Supply Chain Director, signed a written supply agreement with the respondent to run until 31 December 2019. The appellant alleged it discovered the agreement during an internal audit in July 2019 and claimed Cynthia had no authority to sign it. The appellant filed an application in the High Court on 11 June 2020 seeking a declaratur that the agreement was void, invalid and of no legal effect, alleging: (i) Cynthia lacked authority; (ii) the agreement contravened the Competition Act (exclusivity clause); (iii) it violated Exchange Control Regulations (requiring payment outside Zimbabwe without approval); (iv) it breached import licensing requirements; and (v) it was procedurally irregular. The respondent opposed, contending that Cynthia had ostensible authority, a similar prior agreement had been signed in October 2017, the appellant's senior officials knew of the agreement, the parties had performed under it, and the agreement provided for amendments of any offensive clauses.
