The plaintiff operated a foreign currency account with the defendant bank. On 25 February 2003, after instructing a telegraphic transfer of US$11,000, the plaintiff was approached by a bank employee, Murape, who asked if he had US$5,000 for sale. The plaintiff's nephew, Tapiwa Madzimure, offered to deposit foreign currency into the plaintiff's account for sale. The plaintiff's wife later signed a blank withdrawal slip and left it with Murape. Tapiwa never made the deposit, but Murape fraudulently completed the withdrawal slip and withdrew US$5,000 from the plaintiff's account, which only had a balance of US$694.11. Murape later transferred US$2,600 from his own account, leaving a shortfall of approximately US$2,400. The plaintiff sued for this amount, alleging vicarious liability of the bank for Murape's actions and negligence by other bank employees in processing the withdrawal despite insufficient funds.
The plaintiff's claim was dismissed with costs awarded to the defendant.
An employer is not vicariously liable for the fraudulent acts of an employee where: (1) the stolen property was not entrusted to the employee's care by the employer; (2) the employee substantially deviated from his appointed duties and was acting for his own benefit; and (3) the employee was merely taking advantage of opportunities presented by employment rather than acting within the course and scope of employment. The test for vicarious liability requires establishing the appointed duties of the employee and assessing the degree of deviation therefrom. Where an employee is on a frolic of his own, the employer escapes liability unless negligent in some other respect. To establish negligence, a plaintiff must prove both breach of duty and causative negligence using the sine qua non test.
The court expressed reservations about the wholesale importation of the doctrine of ostensible authority from contract law into the law of delict, noting that such importation may serve to distort the distinctions between these two branches of law. Makarau J observed that claims can be brought in contract or delict on the same facts as long as the necessary averments are made, but that importing contractual doctrines into delict may shift the test for vicarious liability too radically. The court noted that one does not expect a bank to have a system that is 100% fool-proof to avoid liability for negligence, applying the standard of the reasonable person (diligens paterfamilias) who exercises moderation and prudent common sense. The court emphasized that vicarious liability should not be viewed only from the perspective of the injured party but should maintain balance and not unjustly expose employers to damages for employees who abandon their duties to injure both third parties and the employer.
This case provides important guidance on the limits of vicarious liability in banking contexts and employee fraud cases in Zimbabwean law (which shares common law principles with South Africa). It clarifies that employers are not vicariously liable when employees substantially deviate from their appointed duties and act for purely personal gain, even if the employment provided the opportunity for the wrongdoing. The judgment critically examines the role of ostensible authority in delictual claims, questioning the wholesale importation of this contractual doctrine into tort law. It emphasizes that vicarious liability is not synonymous with strict liability and must balance the interests of injured parties against unjust exposure of employers to liability for rogue employees. The case also clarifies that establishing negligence requires proof of causative negligence, not merely systemic imperfections.
