The plaintiff instituted action on 19 May 2011 claiming US$23,235.00 for the hire of two tipper trucks and one front end loader allegedly hired by the defendant in October 2010. The plaintiff claimed an oral contract was concluded providing for daily fees of US$600 per tipper and US$300 for the loader. According to the plaintiff's Operations Manager, Pesanai Mombe, he was contacted by Augustine Nzuma (introduced as defendant's Finance Director) and one Murata (introduced as Operations Director) about hiring equipment. The defendant initially hired a loader for seven days and paid US$2,100. The equipment was used at defendant's Kupukai Mine. When the plaintiff presented an invoice for US$31,205.25, the defendant failed to pay, complaining the amount was excessive. The plaintiff revised the invoice to US$23,350 but this remained unpaid. The defendant denied entering into any contract with the plaintiff, claiming instead that a South African company, ZIZWE (Pty) Ltd, represented by Johane Rautenbach, had hired the equipment. According to Nzuma, Rautenbach had an agreement to buy chrome from the defendant and hired the equipment to boost output, with the defendant merely receiving correspondence on Rautenbach's behalf.
The plaintiff's claim was dismissed with costs.
In a civil action, the plaintiff bears the onus of proving its case on a balance of probabilities. Where the plaintiff's evidence is inconsistent with the facts pleaded in its declaration and where the plaintiff fails to produce corroborative documentary evidence such as receipts for alleged previous payments under the same contract, such inconsistencies and omissions discredit the plaintiff's evidence to the extent that the plaintiff fails to discharge its onus of proof. A plaintiff must prove that the contract was entered into with the defendant and not with a third party.
The court observed that the evidence tendered on behalf of both parties was thoroughly unsatisfactory and in some respects inconsistent with the pleadings filed on their behalf. The court noted inconsistencies in the defendant's case as well, including that the defendant's plea suggested a contract with ZIZWE (Pty) Ltd to work on defendant's claims, but Nzuma's evidence denied such a contract and instead referred to an agreement with Rautenbach for purchase of minerals. The court noted that the defendant's witness referred to a written agreement between the plaintiff and Rautenbach but never produced a copy of that agreement. Despite these observations about the defendant's evidence, the court emphasized that the onus remained on the plaintiff.
This case demonstrates the importance of consistency between pleadings and evidence in civil litigation, and reinforces the principle that a plaintiff bears the onus of proving its case on a balance of probabilities. It illustrates that where a plaintiff's evidence contains material inconsistencies with its pleaded case and lacks corroborative documentary evidence (such as receipts for previous payments), the court will find that the plaintiff has failed to discharge its burden of proof. The case is also relevant for contract law principles regarding proof of the identity of contracting parties.
