Mobil Oil Zimbabwe (Private) Limited v Albert Machengete Mashoko

The appellant, Mobil Oil Zimbabwe, entered into a lease agreement with the respondent for operating a service station. The lease agreement contained a material condition that the respondent would acquire all fuel, lubricants and related products exclusively from the appellant and sell only these products from the leased premises. The agreement also required the respondent to be wholly responsible for the control and conduct of all persons employed at the service station (clause 18.5.2). The respondent's senior employees clandestinely purchased fuel from a third party and arranged for delivery at the leased premises in the middle of the night, intending to sell it without the knowledge of either the appellant or the respondent. A deposit of $7 million paid by the employees to the third party had been stolen from the day's takings at the service station. The appellant's representative caught the employees red-handed while taking delivery of the fuel. The appellant then cancelled the lease agreement, citing the respondent's failure to exercise adequate control over his employees. The respondent approached the High Court, which set aside the cancellation. The appellant appealed to the Supreme Court.

• Whether the respondent breached the lease agreement by failing to exercise adequate control over his employees as required by clause 18.5.2
• Whether the doctrine of vicarious liability applies in contract law to terminate a valid contract based on a breach occasioned by employees
• Whether clause 18.5.2 was valid and enforceable despite referencing a non-existent provision (clause 4.8.1)
• Whether the breach, if established, was material enough to warrant cancellation of the lease agreement

1. The appeal was allowed. 2. The decision of the court a quo was set aside and substituted with: (1) The application is dismissed with costs; (2) The respondent's counter application is granted. 3. Costs were awarded to the appellant on an ordinary scale (not the higher scale requested).

1. The doctrine of vicarious liability in delict has no equal application in the law of contract. 2. A contractual clause requiring a party to be wholly responsible for the control and conduct of employees creates a direct contractual obligation, breach of which can justify cancellation of the agreement. 3. A reference in a contractual clause to a non-existent provision does not nullify the entire clause where the parties' intention can be determined from the context and purpose of the agreement. Such erroneous references can be expunged or ignored without doing harm to the parties' intention. 4. Where the very essence of a contract requires exclusive dealing (such as selling only the lessor's products), and a lessee's failure to adequately control employees leads to conduct that violates this fundamental purpose, this constitutes a breach of a material term going to the root of the contract, justifying cancellation. 5. The obligation to control employees in a 24-hour operation requires continuous, adequate supervisory measures, and laxity in such controls that enables fundamental breaches of the contract's purpose constitutes a material breach.

The court observed that the appellant must take part of the blame for using the term 'vicarious liability' in the wrong context, which to some extent misled the respondent as to the case he was facing. This observation justified the court's decision to award only ordinary costs rather than the higher scale of costs sought by the appellant. The court also noted that the issue of whether vicarious liability applied in contract law to terminate a valid contract was somewhat res nova (a new matter) in the jurisdiction, though it ultimately found this framing to be misconceived.

This case is significant in Zimbabwean contract law for clarifying that the doctrine of vicarious liability as understood in delict law does not apply in the same manner in contract law. The case establishes important principles regarding the interpretation of contractual terms requiring a party to control employees' conduct, and the circumstances under which failure to exercise such control constitutes a material breach justifying cancellation of a lease agreement. The judgment also provides guidance on the interpretation of contractual clauses containing references to non-existent provisions, holding that such technical defects do not necessarily invalidate the clause if the parties' intention can be determined from the context. The case demonstrates the courts' willingness to look beyond labels like 'vicarious liability' to the true substance of contractual obligations and their breach.
