On 17 May 2014 at approximately 3:50 a.m., a collision occurred at Shangani along the Bulawayo road between a bus owned by the plaintiff and a tractor and trailer owned by the defendant. The plaintiff's bus was traveling from Mutare in misty conditions. The defendant's tractor, driven by his employee Ndaba Jena, was carrying ore and was partly in the left lane. The tractor had no reflectors, rear lights, or warning signs. Upon impact, the tractor driver could not be found at the scene. The defendant arrived shortly after and assisted with contacting police and taking injured persons to hospital. The defendant's driver subsequently paid an admission of guilt fine for driving without lights and warning signs. The bus, which was only four months old, sustained extensive damage and was written off. The defendant contested liability on grounds that his employee was acting outside the scope of employment, as there were standing instructions against driving on public roads and against driving after sunset or before sunrise. The employee's normal hours were 7 a.m. to 3 p.m., and his job was to transport ore from the mine to the processing plant via private farm roads.
Judgment entered against the defendant for: (a) Payment of US$64,643.20; (b) Interest on US$64,643.20 at the prescribed rate from date of judgment to date of payment in full; (c) Costs of suit.
The binding legal principle is that where an employee has general authority to operate an employer's vehicle (such as keeping the keys and using it for work purposes), a prohibition against driving on public roads or at certain times constitutes a prohibition dealing with conduct within the sphere of employment, not one that limits the sphere of employment itself. Violation of such a prohibition does not automatically remove the employer's vicarious liability. The employer bears the onus of proving that the employee was on a frolic of his own and acting outside the course of employment. The standard test for vicarious liability is whether the employee was engaged in the affairs or business of the employer when the delict occurred, with the determining factor being the degree of deviation from the employer's business. In assessing damages in delictual claims, the purpose is to place the plaintiff in the position it would have been had the delict not occurred, calculated as the difference between pre-collision value and salvage value.
The court made several non-binding observations: (1) The defendant was lax in defending the claim, including confusion about whether he was sued personally or as director of a company; (2) Both parties made a poor show in not leading evidence on the layout of the scene of the accident, which should have been secured at pre-trial conference stage; (3) The obligation to secure such evidence lies on the party seeking to make a claim, and the absence of a comprehensive police report is no excuse; (4) The defendant could have conducted a proper valuation if he seriously contested the plaintiff's damage assessment; (5) Issues regarding quotations for repairs and valuation could and should have been resolved at the pre-trial conference stage; (6) The court noted with interest that nothing was done to establish the whereabouts of the employee immediately after the accident, no issue was made of potential theft of ore or unauthorized use of the tractor, and no disciplinary charges were preferred despite the damage caused.
This case provides important guidance on the application of vicarious liability principles in Zimbabwe (and by extension South African law given the shared legal heritage). It clarifies the distinction between prohibitions that limit the sphere of employment versus those that merely regulate conduct within the sphere of employment, following the principles in Plumb v Cobden Flour Mills and as applied in Wentworth-Wear v Zvipindu. The case demonstrates that an employer bears the onus of proving that an employee was on a frolic of his own, and that mere violation of employment instructions does not necessarily take an employee outside the scope of employment. The case also illustrates the importance of conducting proper investigations and preserving evidence when defending vicarious liability claims.
