Challenge Wisdom Pawandwa Mukamba t/a Mukamba Architectural Practice v Christ Embassy Zimbabwe

The plaintiff, an architect, sued the defendant church for fees claimed for architectural services in designing a church building. The plaintiff was initially contracted by Huni, a church member, to design drawings to persuade Harare City Council to allocate a church stand, for which he was paid. After the defendant obtained the stand in May 2007, the defendant's Building Committee approached the plaintiff through its chairman, Mr Parehwa. The plaintiff claims they entered into a verbal contract whereby he would provide architectural services for 7% of the construction costs. He alleges he proceeded to design brief, preliminary and final design stages. The defendant denies any contract existed, claiming it sent a letter of intent requesting the plaintiff to submit his proposed fees in definite figures before a contract could be concluded. The plaintiff produced drawings dated April 2006, claimed fees based on a Quantity Surveyor's estimate of US$12 million (Z$8.4 trillion), and sought payment. The defendant refused payment, asserting no contract was formed as the plaintiff never provided actual fees as requested.

• Whether the parties entered into a binding contract for architectural services
• Whether a verbal agreement was reached despite the defendant's written letter of intent requiring definite fees
• Whether the plaintiff's conduct and the defendant's signing of various documents (design brief, program of works) constituted acceptance of a contract
• Whether there was a common mistake as to whether a contract had been concluded
• Whether the plaintiff was entitled to fees for services allegedly rendered

The plaintiff's claim was dismissed with costs.

A contract does not come into existence where one party clearly communicates in writing that specific conditions (such as provision of definite fee amounts) must be met before a contract will be concluded, and those conditions are never satisfied. The plaintiff's unilateral belief that a contract existed, and his commencement of work, does not create a binding contract where the defendant consistently maintained its position that definite fees were required before contract formation. Where parties appear to be cooperating but have fundamentally different understandings about whether a contract exists, and written evidence supports one party's version that only pre-contractual negotiations were occurring, no binding contract arises. A party claiming fees for professional services must prove both the existence of a contract and that the work claimed was actually performed.

The court observed that while the parties may have been operating at a tangent - with the plaintiff believing a contract existed while the defendant believed they were still in pre-contract negotiations - this did not constitute a mutual mistake vitiating consent because both parties had clearly stated their respective positions in initial correspondence. The court noted that the Architects' regulations require architects to charge fees as percentages rather than fixed amounts, but this did not prevent a client from insisting on receiving definite fee calculations before agreeing to engage an architect. The court also commented on irregularities in the plaintiff's fee calculation, including use of a gross floor area not agreed by the defendant, reliance on a quantity surveyor who was never formally appointed, and questionable currency conversion rates. The court observed that the drawings produced appeared to be those prepared for Huni in 2006 rather than new work for the defendant, given their dating, lack of site reference, and impossible scale ratios.

This case is significant in Zimbabwean contract law for establishing principles regarding formation of contracts for professional services. It emphasizes that where parties exchange written correspondence clearly stating pre-conditions for contract formation, those conditions must be met before a binding contract exists. The case illustrates the doctrine that parties' minds must meet on essential terms (consensus ad idem) for a valid contract. It is particularly relevant to professional service contracts, confirming that professionals cannot unilaterally assume a contract exists based on their own interpretation when the other party has clearly communicated different requirements. The case also demonstrates the importance of documentary evidence in determining contractual intention and the high evidential burden on a party claiming a verbal agreement contradicts clear written communications.
