The appellant (CBZ Bank Limited) issued summons against the respondent (Dr Alpha Abiot Moyo) claiming $411,340.72 with interest at 28% per annum. The claim arose from four agricultural credit facilities (facility letters) signed by the respondent between 2010 and 2012. The first facility was for $20,000 (February 2010), the second for $80,000 including winter wheat and rollover (May 2010), the third for $190,000 as an overdraft facility for summer cropping (November 2010), and the fourth for $230,000 (March 2012). Each facility letter was accompanied by increasing security, including mortgage bonds over the respondent's immovable property (Lot 2 of Lot 1 of Waterfalls Induna), cession of insurance policy, and crop stop orders. The respondent's account showed negative balances throughout the period, and he continued to access funds through drawdowns despite the negative balance. The respondent defended the action, alleging errors in the bank's calculation of his indebtedness but not denying signing the facility letters or offering security. The magistrate's court dismissed the claim on the basis that no money was deposited into the respondent's account, thus the bank had not proved it loaned the respondent the sum claimed.
The appeal succeeded with costs. The judgment of the magistrate's court was set aside and substituted with the following order: (1) The defendant shall pay the plaintiff $411,340.27; (2) The defendant shall pay interest at 28% per annum from the date of summons to date of payment in full; (3) The immovable property (Lot 2 of Lot 1 of Waterfalls Induna of Waterfalls, 4311 square meters, held under deed of transfer 6126/93) is declared specially executable; (4) All moveable properties in the defendant's name are declared specially executable; (5) The defendant shall pay costs of suit on the legal practitioner and client's scale. No collection commission was awarded.
The binding legal principles established are: (1) An overdraft facility constitutes a loan by the bank to the customer, even when no physical deposit is made into the account - the lending occurs when the bank allows the customer to drawdown funds despite insufficient balances; (2) In proving indebtedness arising from overdraft facilities, a bank need not prove actual deposits but may rely on facility letters, bank statements, and evidence of drawdowns to establish the debt on a balance of probabilities; (3) A customer who receives regular bank statements over an extended period and fails to raise queries within the stipulated timeframe (typically stated on the statements themselves) is deemed to have accepted the accuracy of those statements and cannot later challenge the debt based on alleged errors never previously raised; (4) In civil cases, the standard of proof on a balance of probabilities requires that the probabilities preponderantly favor one party's version, not merely that they slightly favor it - the evidence must be such that the court can say 'we think it more probable than not'; (5) An appellate court will interfere with a trial court's findings of fact where those findings are contrary to the evidence adduced, based on wrong principles of law, or where the trial court failed to consider relevant evidence or considered irrelevant matters.
The court made non-binding observations that: (1) While production of vouchers showing specific drawdowns might have added weight to the bank's case, such evidence was not necessary where the case had already been established on a balance of probabilities through other documentary evidence; (2) It is unwise and inconsistent with commercial honesty for a party to challenge matters of which they were aware over a long period only when sued - citing African Banking Corporation of Zimbabwe Ltd v Sunjet Development Holdings (Pvt) Ltd HH 190/14; (3) The respondent's conduct in not protesting against the increasing debt over three years while continuing to sign facility letters with rollover provisions was inconsistent with someone who genuinely believed there were calculation errors; (4) The respondent was 'simply being dishonest in denying a liability he knew he had incurred'; (5) There was no justification for awarding collection commission where the appellant had already been awarded costs of suit.
This case is significant in Zimbabwean banking law as it clarifies the nature of overdraft facilities and the standard of proof required for banks to recover debts arising from such facilities. It establishes that banks need not prove actual deposits into accounts to establish lending through overdraft facilities, as the essence of an overdraft is allowing customers to drawdown beyond available balances. The case reinforces the principle that bank statements and facility letters, when uncontradicted and accepted over time by a customer, constitute sufficient proof of indebtedness on a balance of probabilities. It also affirms that customers who receive regular bank statements and fail to raise queries within stipulated timeframes cannot later deny liability based on alleged calculation errors never previously raised. The judgment provides important guidance on appellate review of trial court decisions, reiterating the limited grounds for interference with lower court findings.
