The plaintiff entered into an agreement of sale (Exhibit 1) with the defendant, as executor dative of the late I.V. Rukatya's estate, to purchase plot No. 339 Mkwasine Settlement Holdings, Ndanga District. The agreement required staged payments totaling Z$750 million. The plaintiff paid Z$350 million but thereafter the parties allegedly agreed to change the payment method from cash to sugar (in kind). The plaintiff claimed that the defendant's office drew up a subsequent agreement reflecting this new arrangement, which the plaintiff signed and returned. However, this subsequent agreement was never signed by or on behalf of the defendant. The defendant subsequently cancelled the agreement, claiming the plaintiff was in default. The plaintiff sued for specific performance, seeking an order that the cancellation be set aside and that transfer of the property be effected.
The court granted absolution from the instance in favor of the defendant.
Where parties to an agreement of sale mutually abandon their initial agreement by attempting to conclude a subsequent compromise agreement, but the subsequent agreement is never validly concluded (through failure of signature by or on behalf of one party), no enforceable agreement exists between the parties. A principal is estopped from denying the authority of an agent who has previously acted on his behalf and held out as having such authority, but an unsigned agreement purportedly prepared by that agent does not bind the principal. Mutual abandonment of an agreement occurs when parties attempt to replace it with new terms, even if the replacement agreement ultimately fails.
The court observed that the plaintiff could potentially lead other evidence upon which he might eventually succeed, suggesting that the dismissal through absolution from the instance was without prejudice to the plaintiff bringing fresh proceedings with additional evidence. The court also made the general observation that it is trite law that an agent can bind his principal if acting within his mandate, reinforcing established agency principles.
This case illustrates important principles in Zimbabwean contract law regarding the mutual abandonment of contracts, the authority of agents to bind principals, and the requirements for formation of valid agreements. It demonstrates that when parties attempt to replace an existing agreement with a new one, but the new agreement fails to materialize (due to lack of signature or other formalities), the original agreement may be deemed mutually abandoned, leaving no enforceable contract between the parties. The case also reinforces the principle of estoppel in agency relationships and the requirement that agreements for the sale of land must be properly executed by or on behalf of all parties.
