G C Bushby, a shareholder and managing director of both appellant companies, entered into discussions with Knight Frank & Rutley (acting for the respondent) for the lease of property at 21 Eddison Crescent, Graniteside, Harare. On 11 September 1995, Knight Frank communicated the respondent's offer to lease the property for three years commencing 1 October 1995 with specified rental amounts. Bushby signed the letter of acceptance on 13 September 1995, but added a handwritten addendum making acceptance subject to confirmation of the number of working telephone lines and additional costs. Knight Frank responded on 15 September 1995 providing the requested information. On 20 September 1995, the second appellant returned the signed letter of acceptance, requested keys to the property, and indicated a company guarantee was being prepared. The appellants later disputed that any binding agreement had been concluded, arguing that Bushby lacked authority to conclude an agreement without board approval, that acceptance was conditional, and that the respondent was not the property owner and therefore lacked standing to claim damages.
The appeal was dismissed with costs.
The binding legal principles established are: (1) An oral agreement is binding even if the parties intend to reduce it to writing, unless the parties expressly agree that the agreement is to be of no force or effect until reduced to writing (citing Patrikios v African Commercial Company 1940 ST 45 at 57 and Karedzera v Geoman Construction and Nembawane SC-76-96). (2) Under the doctrine of undisclosed principal, an agent acting on behalf of an undisclosed principal has locus standi to sue on the contract, even after the existence of the principal becomes known to the other party. (3) A lessee may not dispute the lessor's title once a lease agreement has been concluded (citing Robinson v Grimm 1996 (2) ZLR 83, Clark v Nourse Mines Ltd 1910 TS 512, and Kala Singh v Germiston Municipality 1912 TPD 155). (4) Where acceptance is made subject to conditions, the satisfaction of those conditions and subsequent conduct consistent with contract formation demonstrates that a binding agreement has been concluded.
Muchechetere JA made obiter observations regarding costs, noting that while there was merit in the submission that costs should be awarded on a legal practitioner and client scale due to the weak grounds of appeal and lack of proper particulars in the notice of appeal, the Court declined to make such an order. The learned judge observed that the deficiencies could be attributed to the appellants' legal practitioners' lack of diligence and failure to advise their client properly, rather than to vexatious conduct by the appellants themselves. The Court also noted obiter that had an application for joinder of Ben Brack been made, it would have been granted, as the amendment raising the ownership issue was served very late (on the day of trial) without proper notice, and there would have been no prejudice to the appellants in adding the proper plaintiff.
This case is significant in Zimbabwean contract law for establishing several important principles: (1) it confirms that oral agreements are binding even where parties intend to reduce them to writing, unless there is express agreement that no binding contract exists until written formalities are completed; (2) it applies the doctrine of undisclosed principal, allowing an agent to sue on a contract even after the existence of the principal becomes known; (3) it reaffirms the common law principle that a lessee may not dispute the lessor's title once a lease agreement has been entered into; and (4) it demonstrates how conditional acceptance can ripen into binding agreement once conditions are satisfied and parties conduct themselves in a manner consistent with contract formation. The case provides important guidance on determining when negotiations crystallize into binding contractual obligations.
