On 11 December 1994, a traffic accident occurred at the 144 kilometre peg at the Angwa River Bridge on the main road between Chinhoyi and Karoi in Zimbabwe. The appellant's bus collided with a trailer attached to a tractor driven by the respondent's deceased employee. The collision occurred at approximately 7 pm in dark and rainy conditions. The deceased tractor driver moved the tractor from the dirt verge onto the tarred road surface, causing the front left of the bus to collide with the trailer. The bus careered off the road and struck trees, causing considerable damage. The deceased driver was driving an unlicensed vehicle without lights, had no driver's licence, and had probably consumed alcohol. The respondent had specifically instructed the deceased to use a back road through the farm to transport workers between camps, to operate only in a private area, to cease operations by 4:30 pm (before dark), and to cross the public road only during daylight following specific procedures. The deceased violated all these instructions. The appellant bus company sued the respondent employer for damages arising from the accident.
The appeal was dismissed with costs.
An employer will not be held vicariously liable for the delictual acts of an employee where the employee's conduct involves express disobedience of instructions that limit the sphere of employment, rather than instructions that merely regulate conduct within that sphere. Where an employee is specifically forbidden from engaging in particular conduct (such as driving on a public road, driving at night, or driving an unlicensed vehicle) and the employee flagrantly violates these prohibitions, the employee is not acting within the course and scope of employment. Vicarious liability requires that it be reasonably foreseeable that the employee would act in the manner complained of; where an employee defies express prohibitions in a manner no reasonably prudent employer could foresee, the employer cannot be held vicariously liable for the resulting damage.
The Court noted that because it found the respondent was not vicariously liable, it was unnecessary to determine whether the quantum of damages had been properly established by the appellant or to consider the issue of contributory negligence. The Court also made general observations about the need to strike a balance in vicarious liability cases between protecting innocent third parties and avoiding the imposition of blanket liability on employers for all negligent acts committed by employees during employment. The Court cited with approval the principle from Gorah that courts should not adopt an approach that would lead to too zealous a restriction of vicarious liability, while also recognizing the inequity of imposing liability on parties not actually at fault.
This Zimbabwean Supreme Court case is significant for its application of the principle of vicarious liability in delict/tort law, particularly in determining when an employer can be held liable for an employee's wrongful acts. The case reinforces the distinction between instructions that merely regulate conduct within the sphere of employment versus instructions that limit the sphere of employment itself. It demonstrates that where an employee flagrantly violates express prohibitions (rather than merely performing authorized duties negligently or improperly), the employer may escape vicarious liability. The case contributes to the jurisprudence on balancing public policy considerations of protecting innocent third parties against the inequity of imposing liability on employers who have taken reasonable precautions and given clear instructions. While this is a Zimbabwean case, it applies legal principles common to South African law on vicarious liability, citing several South African precedents including cases from the Appellate Division.
