Hortico Produce (Private) Limited v Tafula Properties (Private) Limited

Hortico (appellant) was a vegetable exporter and Tafula (respondent) was a grower. They entered into an agreement for Tafula to sell mange tout peas to Hortico. A letter dated 13 October 1998 from Hortico to Tafula specified prices for different grades (A and B) at different periods, with volumes subject to adjustment. During 23 October 1998 to 12 November 1998, Tafula sold peas to Hortico, who collected them from Tafula's farm (an exceptional arrangement as other suppliers delivered to Hortico). Hortico paid $81,963.50 but Tafula claimed it was short by $233,029.00, seeking payment of $314,992.50 in total. The dispute arose from conflicting versions of the contract. Tafula claimed the contract included oral terms that: only Grade A peas would be delivered; substandard peas would be returned and the contract cancelled; overgrown/undergrown peas were unacceptable. Tafula argued all its deliveries were Grade A as nothing was returned. Hortico claimed it had the right to grade the peas itself, and only 11.63% were A grade and 20.66% were B grade, with the balance unacceptable and disposed of. Because Hortico collected the peas (using its own driver), the usual practice of growers picking up grading reports from Hortico's premises did not occur, so Tafula was unaware of the low grades until later.

• Whether the contract between the parties included oral terms that only Grade A peas would be delivered and accepted
• Whether the contract provided that substandard peas would be returned and the contract cancelled if even a single pea was below Grade A
• Whether Hortico had the contractual right to determine the grading of peas supplied by Tafula
• Whether Tafula proved the contract it alleged on a balance of probabilities
• Whether the appeal court should disturb findings based on credibility assessments by the trial court

The appeal succeeded with costs. The order of the court a quo was altered to read: "Absolution from the instance, with no order as to costs."

In commercial contracts, particularly in specialized export industries, a party asserting that a contract includes oral terms which are commercially improbable or inconsistent with written terms bears the burden of proving such terms on a balance of probabilities. Where an exporter deals with suppliers and has exacting quality standards imposed by international buyers, the court will presume that the exporter retains the right to grade products according to those standards, and will not accept that the exporter agreed to be bound by the supplier's grading. A claim that a contract required absolute perfection (that even a single substandard item would result in return of the entire lot and cancellation) will be rejected as improbable in the absence of special circumstances. On appeal, where credibility findings are challenged, courts may apply a probabilities test rather than defer entirely to the trial court's demeanor-based assessments, particularly where the record does not support significant differences in evidence quality.

McNally JA observed that credibility assessments based on demeanor are problematic, quoting Diemont JA in S v Kelly that demeanor "is, at best, a tricky horse to ride." The Court noted that it was possible there was never a true meeting of minds between the parties, and Tafula's managing director may have genuinely believed his version of the contract was correct, without necessarily being untruthful. The Court commented that the contract letter was "very badly drafted" and its "wording left a great deal to be desired." The Court expressed sympathy for Tafula's position, noting it was "very unfortunate" that Tafula was not made aware of the grading earlier, and acknowledged this was due to Hortico's unusual collection arrangement and failure to communicate grade reports. The Court noted that Tafula may not have realized how exacting British supermarket standards were and may not have believed such a low percentage of its peas would be rejected, but emphasized this was not a case about whether Hortico fraudulently undergraded the peas.

This Zimbabwean Supreme Court case is significant for its application of contract law principles, particularly regarding the interpretation of contracts and the burden of proof. It illustrates the importance of applying a probabilities test where credibility findings are disputed on appeal, rather than relying solely on demeanor assessments. The case demonstrates that courts will assess the commercial reasonableness of alleged contractual terms, particularly in specialized industries with exacting standards (such as export agriculture). It establishes that where a party alleges specific oral terms that are commercially improbable or inconsistent with written terms, they will fail to discharge the burden of proving the contract on a balance of probabilities. The case also shows judicial discretion in making equitable costs orders where the successful party had some fault (here, Hortico's failure to communicate grading results).
