Chifamba, a member of Rixi-Taxi Cooperative Society, became entitled to use a Hyundai Excel motor vehicle purchased by Rixi-Taxi on hire-purchase from Stannic in June 1997. In September 1997, he entered into an arrangement with Merinyo concerning the vehicle. Chifamba claimed he verbally leased his right to use the Excel to Merinyo for $5,000 monthly rent, which Merinyo paid for four months before stopping, and then refused to return the vehicle. Merinyo contended that he purchased the Excel from Chifamba for $250,000 payable in monthly instalments of $5,000, later increased to $6,000 and then $7,000. Merinyo claimed he paid regularly until August 1999 when he experienced financial difficulties. He drafted a written sale agreement but Chifamba refused to sign because the vehicle was still subject to hire-purchase with Stannic. In October 1999, Chifamba took the Excel from Merinyo, but Merinyo obtained a spoliation order (HC 16209/99) compelling its return. Chifamba then sued for return of the vehicle or $500,000 damages.
The application was dismissed with costs.
In civil litigation, where a plaintiff's case rests entirely on his own uncorroborated testimony and that testimony is found to be unreliable, contradictory, and inconsistent with the probabilities, the plaintiff will fail to discharge the onus of proof on a balance of probabilities. A court is entitled to reject a party's testimony where that party is demonstrably evasive, contradictory, and unable to provide reasonable explanations for conduct that would be inconsistent with his pleaded case. Where the defendant presents credible testimony that accords with the probabilities and is not shaken under cross-examination, and the plaintiff fails to call available corroborating witnesses, the court may accept the defendant's version and dismiss the claim.
The court noted counsel's attempt to explain Chifamba's poor performance as a witness by reference to his age, diabetes, and high blood pressure affecting him under stress during lengthy cross-examination. However, the court did not accept this explanation as sufficient to account for the fundamental inconsistencies and implausibilities in his evidence. The court's observation that even Chifamba's own counsel appreciated how bad a witness he was reflects the severity of the credibility problems. The judgment also implicitly comments on the importance of reducing agreements to writing and obtaining proper signatures, as Merinyo's failure to insist on Chifamba signing the written sale agreement created the dispute, though ultimately the court accepted his version based on the probabilities and credibility assessment.
This case illustrates the critical importance of credibility assessment in civil litigation where the outcome depends on competing oral testimony. It demonstrates that a plaintiff bears the burden of proving his case on a balance of probabilities and that uncorroborated testimony from an unreliable witness will not suffice, particularly where the defendant presents a coherent and credible alternative version supported by the probabilities. The case also highlights the courts' approach to evaluating witness demeanor, consistency, and whether evidence accords with probabilities.
