Rusitu Agencies (Private) Limited v Peter Fungayi Kangara

The plaintiff, Rusitu Agencies (Private) Limited, a cigarette distributor for British American Tobacco Zimbabwe Limited (BAT), claimed US$14,287 from the defendant based on an acknowledgment of debt. The plaintiff alleged this amount was owed for cigarettes sold to the defendant on credit. The plaintiff supplied cigarettes to approved stockists on a 7-day credit basis. Two invoices formed the basis of the claim: one dated 22 September 2010 with an outstanding balance of US$1,717, and another dated 4 October 2010 for US$12,570. According to the plaintiff's witnesses (Managing Director Chiwara and salesman Bushu), when payment was not forthcoming, they met with the defendant on 14 October 2010 after rescuing him from a vehicle breakdown. In Chiwara's vehicle outside the defendant's Norton shop, the defendant acknowledged the debt and signed an acknowledgment of debt document. The defendant denied signing the document, claiming it was a forgery, and denied owing any money to the plaintiff. He claimed all transactions were cash-based and that he had paid all amounts due to Bushu at the time of delivery, though he had destroyed all payment records.

• Whether the defendant was indebted to the plaintiff in the sum claimed
• Whether the defendant signed the acknowledgment of debt
• Whether the signature on the acknowledgment of debt was that of the defendant
• Whether the onus of proving payment rested on the defendant

The defendant was ordered to pay the plaintiff US$14,287.00 together with interest at the prescribed rate from the date of issuing summons to the date of payment in full, plus costs of suit on the ordinary scale.

The binding legal principles established are: (1) In a claim based on an acknowledgment of debt, once the creditor proves the existence of the signed acknowledgment, the onus shifts to the debtor to prove payment or that the acknowledgment is invalid; (2) The onus of proving payment rests on the person who alleges payment was made, in accordance with the principle that the onus is on the person who affirms and not on him who denies; (3) Where a defendant alleges forgery of an acknowledgment of debt but fails to provide credible evidence to support this allegation, and the plaintiff provides consistent and credible testimony regarding the circumstances of signing, the court will accept the plaintiff's version on a balance of probabilities; (4) The destruction of business records relevant to a dispute, particularly after litigation has commenced, will result in adverse inferences being drawn against the party who destroyed such records.

The court noted that while the plaintiff's prayer for costs on a higher scale was understandable (presumably given the defendant's conduct in the litigation and the allegation of forgery), it would be fair to award costs on the ordinary scale. This suggests judicial discretion should be exercised with moderation even where a party's conduct may warrant higher costs. The court also made observations about the implausibility of certain conspiracy theories that would have to exist if the defendant's version were true, including that an employer would knowingly conspire with a dishonest employee (Bushu) to defraud a customer, which the court characterized as highly improbable scenarios not supported by the evidence.

This case reinforces the application of the principle that the onus of proving payment rests on the debtor who alleges payment has been made. It demonstrates the importance of credibility assessment in commercial disputes and the court's willingness to draw adverse inferences from the destruction of business records and inconsistencies in testimony. The case also illustrates the evidential value of acknowledgments of debt in Zimbabwean commercial law and the high threshold required to successfully challenge such documents on grounds of forgery.
