Windmill (Private) Limited v Zimbabwe Commercial Farmers Union and Jupiter Insurance

On 17 December 2010, the plaintiff (Windmill) and first defendant (Zimbabwe Commercial Farmers Union - ZCFU) entered into an agreement for the supply of fertilizers to ZCFU's members. The second defendant (Jupiter Insurance) stood as guarantor for the first defendant's obligations. The plaintiff supplied fertilizers totaling USD 1,215,373.00 (inclusive of 10% interest) to various ZCFU members. After partial payments of USD 317,178.88, a balance of USD 898,194.12 remained outstanding. The plaintiff obtained default judgment against the second defendant (guarantor) on 8 February 2012. The first defendant disputed liability, arguing that its individual members who received the fertilizers were the principal debtors, not ZCFU itself. Summary judgment was refused on 12 September 2012, leading to a full trial. The agreement expressly stated in clause 3.2.2 that ZCFU "shall be the customers and principal debtors to WINDMILL." ZCFU's role included mobilization, identification, selection and vetting of eligible farmers, collection of deposits, issuing fertilizer collection documents, and collecting repayments from farmers.

• What were the material terms of the agreement between the plaintiff and defendants regarding the sale of fertilizers to farmers who were members of the first defendant?
• Does the first defendant have any obligation to pay for fertilizers supplied on credit by the plaintiff?
• Has the first defendant been released from any of its obligations under the agreement with the plaintiff?
• Is the first defendant liable to pay the plaintiff the sum of USD 898,194.12?
• Whether the first defendant acted as agent for its members or as principal debtor in the contract?
• Whether joint recovery efforts by the parties varied the original contract terms?

1. The first defendant was ordered to pay the plaintiff USD 898,194.12 with interest at the prescribed rate from 7 October 2011 to the date of full and final payment. 2. The first defendant was ordered to pay costs of suit.

Where parties have reduced their agreement to writing and the written contract expressly designates one party as the "principal debtor," that party remains liable for the full contractual obligation notwithstanding that: (a) the practical beneficiaries of the contract are third parties (the debtor's members); (b) the creditor dealt directly with those third parties in certain circumstances for operational purposes; or (c) the parties engaged in joint efforts to recover amounts from the third party beneficiaries. The express written terms of a contract cannot be contradicted, altered, or varied by oral evidence or by the parties' subsequent conduct in performance, absent formal variation of the agreement. A party's obligations under a written contract remain enforceable even if onerous, and courts will not rewrite contracts or excuse parties from consequences of agreements freely and voluntarily entered into as a matter of public policy.

The court observed that "the best that the first defendant could have done was to negotiate an out of court settlement with the plaintiff," suggesting that given the clear terms of the written agreement, litigation was not a prudent course of action for the defendant. The court also commented that "we are in casu not dealing with issues of sympathy" and that "irrespective of the hardships the law obliges the defendant to pay," emphasizing that public policy requires enforcement of contracts regardless of their burdensome nature. The judge noted that the application for absolution from the instance was dismissed because the plaintiff had presented a prima facie case. The court also remarked that if the parties had intended that the plaintiff would contract with individual farmers rather than with ZCFU, "they would have said so" in the written agreement.

This case reinforces fundamental principles of contract law in Zimbabwe (which shares common law heritage with South Africa): (1) the parol evidence rule - that written contracts cannot be varied by oral evidence; (2) the principle of contractual sanctity - that courts will not rewrite contracts or excuse parties from onerous obligations freely undertaken; (3) that express terms clearly identifying a party as "principal debtor" will be enforced according to their plain meaning; (4) that practical arrangements in performance (such as dealing with third party beneficiaries) do not vary express contractual terms unless formally agreed; and (5) that matters not denied in pleadings are deemed admitted. The case is significant for commercial transactions involving intermediary organizations that facilitate transactions for their members, clarifying that the intermediary remains liable as principal debtor unless the contract expressly provides otherwise or is formally varied.
