In July 2012, the appellant engaged Israel Kembo (first defendant) to survey and site a borehole for irrigation purposes on his farm where he had planted wheat seed, paying him US$150. Kembo sited the borehole position. The appellant then entered into a verbal contract with the respondent (second defendant), a drilling company, to drill and case a 40-metre deep borehole at the sited location for US$1,800. After the borehole was drilled, it failed to yield adequate water for irrigation purposes. Both contractors blamed each other - Kembo blamed the drilling company for poor drilling work, while the respondent blamed Kembo for poor siting. The appellant sued both defendants jointly and severally for specific performance (to resurvey and redrill) or alternatively for payment of US$2,530 (costs incurred plus wasted seed). Israel Kembo defaulted and judgment was entered against him. The trial proceeded against the respondent and was dismissed with costs. The appellant appealed to the High Court.
The appeal was dismissed with costs.
Where parties enter into a contract for specific services, a contractor who completes the precise work contracted for cannot be held liable for inadequate results stemming from another party's prior work or responsibilities. In civil matters, the plaintiff bears the onus of proving his case on a balance of probabilities, including establishing the terms of the contract and proving breach thereof. Where technical or expert matters are in dispute, a party must adduce proper expert evidence rather than relying on unsworn self-exonerating statements from co-defendants. An appellate court will only interfere with factual findings of a trial court where the findings are so outrageous in their defiance of logic or accepted standards that no sensible person applying their mind could have reached such a conclusion, or where the trial court acted on wrong principles, considered irrelevant matters, mistook facts, or failed to consider relevant matters.
The Court noted that the appellant seemed not to appreciate his own case, as the relief sought in terms of specific performance against the respondent was only to apply in the event of absolution from the instance regarding Israel Kembo's claim. Since there was no absolution (a default judgment was entered against Kembo), technically no case for specific performance was made against the respondent even on this basis. The Court also observed that capacity testing would not have changed the quantity of water realized from the borehole in any event. The Court commented that the appellant would have done himself good by calling independent expert evidence if he seriously believed the low water yield was due to the size of drill bits and casings used, rather than relying on a letter from a co-defendant who had an interest in deflecting blame.
This case illustrates important principles in Zimbabwean contract law regarding: (1) the precise determination of contractual terms and obligations in verbal contracts; (2) the allocation of responsibility between independent contractors performing different aspects of a project; (3) the burden of proof in civil matters and the requirement to prove one's case on a balance of probabilities; (4) the necessity of expert evidence to establish technical matters beyond the knowledge of lay witnesses; (5) the limited evidential value of self-serving statements by co-defendants; and (6) the restricted grounds upon which an appellate court will interfere with factual findings of a trial court. The case reinforces that a party must prove the precise terms of a contract and that a contractor who fulfills their specific contractual obligations cannot be held liable for deficiencies arising from another party's work or responsibilities.
