William H. Chirombe v John Mutamburo

The appellant (plaintiff in the lower court) leased his stand 2792 Rujeko North Township Marondera to the respondent (defendant). A written 4-year lease agreement was signed running from 1 March 2013 to 1 March 2017. In 2016, the appellant sued the respondent for $2,800 in arrear rentals and holding over damages. The appellant had initially claimed cancellation of the lease agreement and eviction, but this prayer was abandoned at trial as it was overtaken by events. Evidence showed that the appellant had ceded his rights to receive rent to one Maphious Mutonhori, the prospective new owner of the property, through an oral agreement. The respondent claimed to have paid the arrear rentals to Maphious Mutonhori pursuant to this trio agreement. The Magistrate's Court dismissed the appellant's claim with no order as to costs. The appellant appealed on four grounds, later abandoning two grounds at the hearing.

• Whether the Magistrate erred in law regarding the onus of proof in relation to payment of arrear rentals under a lease agreement
• Whether the respondent had proven payment of the claimed rentals
• Whether the Magistrate erred in finding that the lease agreement had been orally varied
• Whether a non-variation clause in the lease agreement and the parol evidence rule prevented the oral cession of rights to receive rent
• Whether the cession of rights to receive rent to a third party (prospective purchaser) was valid and enforceable

The appeal was dismissed with costs.

The binding legal principles established are: (1) A cession of rights to receive rent under a lease agreement does not constitute a variation of the lease agreement itself, but rather involves the existing creditor ceasing to be creditor and a new creditor taking that position. (2) Such a cession agreement cannot be defeated by a non-variation clause in the original lease agreement or by the parol evidence rule, as it does not alter the substantive terms of the lease contract but only affects who is entitled to receive performance. (3) An appeal court will not interfere with findings of fact made by a lower court where those findings are based on evidence on record and demonstrate no misdirection in the application of legal principles.

The court made observations regarding the parol evidence rule, noting that it is a principle that preserves the integrity of written documents and applies to integrated contracts where parties acknowledge in writing that the document is the complete and exclusive declaration of their agreement. The court clarified that an obvious typographical error in a judgment (such as using "lessor" instead of "lessee") should be read in context and does not constitute a misdirection if the correct principle is otherwise apparent from the judgment as a whole.

This case is significant in Zimbabwean law (applicable in South African jurisprudence for comparative purposes) as it clarifies the legal principles surrounding cession of contractual rights in the context of lease agreements. It establishes that the cession of a right to receive rent does not constitute a variation of the lease agreement itself, and therefore is not subject to non-variation clauses or the parol evidence rule. The case demonstrates the distinction between varying the substantive terms of a contract and assigning or ceding rights under that contract. It reinforces the principle that parties to a lease can validly cede their right to receive rent to third parties through oral agreements, even where the original lease contains a non-variation clause, as such cession affects the identity of the creditor rather than the terms of the lease.
