ABSA Bank sued the respondent, a farmer from Frankfort in the Free State who had been a client since November 1969, for payment of R174,530.87, being the alleged debit balance on his overdraft account plus mora interest. The respondent defended the claim and instituted a counterclaim on the basis that the bank had overcharged him interest in the past. The respondent alleged that in November 1969 he and the bank agreed that interest on his overdraft would be charged at 1% above prime rate, which agreement was in force until 28 March 1992. He alleged the bank charged more than the agreed rate before 28 March 1992, which he paid while unaware of the breach. After March 1992, the respondent paid off his debit balance following a farm sale, his account showed a nil balance for about 3 months, then went into debit again. The respondent admitted he became aware of the alleged overcharging in 1993 but only issued his counterclaim in February 1998. All amounts comprising the claimed sum were debited after 28 March 1992, and the respondent raised no objection to any debits after that date.
The appeal succeeded with costs, including costs of two counsel. The order of the court a quo was set aside and replaced with judgment in favour of the bank (appellant) for: (a) the amount of R174,530.87; (b) interest on this amount calculated at a rate of 2.25% above the prime rate charged by the bank from time to time, from 26 July 1997 until date of payment; (c) costs of suit.
The binding legal principles established are: (1) A bank is not obliged to prove the correctness of historical debits on a client's account where those debits have been extinguished by payment (resulting in a nil balance) and the bank's current claim relates only to subsequent debits which are not disputed. (2) A client's remedy for recovery of interest allegedly overcharged by a bank is the condictio indebiti (action for recovery of undue payment). The fact that transactions occurred on a running account does not alter this fundamental principle. (3) For purposes of prescription under sections 12(1) and 12(3) of the Prescription Act 68 of 1969, prescription begins to run when a creditor has knowledge of the essential facts giving rise to the claim, not when the creditor can finally prove or quantify the claim precisely. (4) The contractual relationship underlying the operation of a current account between a bank and its client is that of creditor and debtor. This does not constitute a fiduciary relationship that would entitle a client to demand delivery and debate of a statement of account, absent a contractual term, statutory provision, or true fiduciary relationship imposing such an obligation. (5) A bank's duty of confidentiality regarding client information does not constitute a fiduciary relationship in the sense required to ground an entitlement to debate of account.
The court observed that while the case appeared simple in retrospect, it had not always been so straightforward, noting that the respondent himself had initially seen fit to employ two counsel when he had obtained judgment in his favour in the court a quo. The court also made the observation that a creditor (the bank) cannot be legally obliged to help determine the amount of a claim against itself by a debtor seeking repayment of amounts allegedly overcharged. The court noted that Mr Redelinghuys's concession in cross-examination that the bank stood in a fiduciary relationship with the respondent appeared to refer to the bank's duty of confidentiality rather than a fiduciary relationship in the true legal sense of that term, and in any event the question was one of law to be determined independently of the witness's opinion.
This case is significant for clarifying several important principles in South African banking and prescription law: (1) It confirms that the relationship between a bank and its client regarding a current account is fundamentally one of creditor and debtor, not a fiduciary relationship for purposes of entitlement to a debate of account. (2) It establishes that a bank is not required to prove the correctness of historical debits on a running account where those debits have been paid off (resulting in a nil balance) and the current claim relates only to subsequent undisputed debits. (3) It clarifies the application of prescription to claims for recovery of overpaid amounts, holding that prescription begins to run when the creditor has knowledge of the essential facts giving rise to the claim, even if the precise quantum still needs to be calculated. (4) It confirms that a claim for a debate of account is itself subject to prescription if it is essentially a claim for repayment of overpaid amounts. (5) The case reinforces that the condictio indebiti is the appropriate remedy for recovery of amounts paid under a mistaken belief of liability.
