Varden Safaris responded to a Forestry Commission advertisement in November 2009 for leasing sites in Hwange for photographic safaris. The plaintiff's tender was successful and a lease agreement was signed in April 2010 for 1000 hectares for wildlife photographic safaris and accommodation. The advertisement promised that actual lease areas, map numbers, and references would be provided with tender forms, but this was not done. At a preliminary meeting on 1 March 2010, a map was circulated but the defendant indicated it contained errors. The same map was later provided to the plaintiff as the final map, though no map was actually attached to the signed lease agreement. After the plaintiff took occupation of the site in July 2010 and commenced clearing and construction work, labourers from Ngamo Safaris (the defendant's hunting subsidiary) were found pumping water into a water pan for a forthcoming sable hunt. The plaintiff discovered the site was designated as a hunting area, not a photographic safari area. The plaintiff cancelled the lease in September 2010 and claimed damages. The defendant pleaded mistake of fact and argued the agreement was void for vagueness, claiming the plaintiff occupied the wrong site.
The plaintiff's claim for damages succeeded in part. The court ordered: (a) Costs relating to preliminary construction activity, including costs for transport and hiring of labour (both professional and manual); (b) Refund of lease fees paid for 2010; (c) Costs of the trial. The claim for loss of expected net income was rejected.
A party cannot avoid a contract on the basis of mistake where the mistake was caused by its own carelessness and failure to provide clear and accurate information, particularly where it possessed superior knowledge about the subject matter. The parole evidence rule does not exclude factual evidence that explains the background and context of an agreement without altering its written terms. Where both parties bear some fault for losses arising from a mistake, damages may be apportioned accordingly, and a party's contributory negligence in failing to take reasonable precautions may reduce their recoverable damages. In commercial lease agreements, the party advertising a lease and possessing knowledge of the property bears the primary responsibility for clearly communicating accurate details about the lease site to avoid mistakes.
The court made observations about proper pleading practice, endorsing the principle that legal points should be properly pleaded and not raised as "ambush" tactics in closing submissions, citing Jane Mutasa v Telecel International. The court noted that it would have been the "reasonable thing to do" for a prudent businessperson in the plaintiff's position to have taken active steps to ensure proper demarcation of the site given the known errors in maps and the site's previous use for hunting. The court also commented on the undesirability of raising issues that were never put to witnesses in cross-examination or addressed in evidence-in-chief, particularly regarding statutory interpretation issues raised by the defendant about ministerial authority under the Forest Act.
This case is significant in Zimbabwean contract law for its application of principles regarding mistake of fact in commercial lease agreements. It establishes that a party cannot rely on mistake to void a contract where that mistake was caused by its own carelessness and failure to provide clear and accurate information, particularly where that party had superior knowledge and control over the relevant information. The case also illustrates the application of the parole evidence rule in circumstances where factual background evidence is necessary to understand the context of a written agreement. Additionally, it demonstrates the principle of apportionment of liability where both parties bear some degree of fault, with the court limiting damages based on the plaintiff's contributory negligence in failing to take reasonable steps to verify boundaries despite being advised to do so and knowing of errors in provided maps. The judgment emphasizes the importance of certainty and predictability in commercial arrangements and the duty of parties, particularly those with superior knowledge, to provide clear and accurate information to avoid mistakes.
