Cecil Nurse (Pty) Ltd v Nkola

Cecil Nurse (Pty) Ltd (appellant) was a manufacturer and supplier of office furniture that traded from Port Elizabeth and East London. The respondent, Nkola, was the sole director and shareholder of FMMC Holdings (Pty) Ltd, a supplier of school and office furniture in Mthatha. FMMC initially purchased goods from the appellant on a cash-on-delivery basis from April 2000. When FMMC needed to establish a showroom in Mthatha requiring stock worth approximately R50,000, the appellant agreed to grant FMMC a credit facility with Nkola standing as surety. On 18 August 2000, the appellant sent a credit application form and deed of suretyship to FMMC for completion. On 23 August 2000, both documents were duly executed by Nkola and returned by fax to the appellant. The original suretyship bound Nkola as surety and co-principal debtor for all present and future obligations of FMMC to the appellant. By 7 December 2000, FMMC had accumulated a debt of R150,653.94 (later reduced to R145,911.54). The appellant sued Nkola on the suretyship. Nkola defended the claim by presenting an 'amended suretyship' that deleted 'future obligations' and added a handwritten clause 13 limiting his liability to R45,600 for the showroom stock. Nkola claimed he had faxed this amended version after the original, but the appellant denied receiving it or consenting to any amendments.

• Whether the creditor was bound by an alleged amendment to a suretyship agreement where the surety claimed to have presented an amended document after initially presenting a duly executed original suretyship
• Whether clause 6 of the suretyship, requiring alterations to be 'agreed to in writing by the creditor', precluded the surety from relying on alleged oral or implied amendments
• Whether the creditor's letter regarding payment terms constituted written consent to amendments to the suretyship
• Whether a surety who presents a duly executed suretyship to a creditor creates a reasonable impression of intention to be bound by its terms
• Who bears the onus of proving the terms of a suretyship agreement and any alleged amendments thereto

The appeal was upheld with costs including costs of two counsel. The order of the court below was set aside and substituted with an order dismissing the appeal with costs, including costs of two counsel. This had the effect of reinstating the magistrate's judgment granting the appellant's claim against the respondent for payment of the debt.

When a party presents a duly executed contract to another party, a binding contract comes into existence immediately upon receipt. Any subsequent proposed amendment constitutes merely a variation to an existing contract, and the party alleging such variation bears the onus of proving it was agreed to. Contractual provisions requiring that variations be agreed to in writing are valid and binding, and parties are entitled to invoke such clauses. A party cannot escape liability under a contract by claiming they presented an amended version when they have already created a reasonable impression that they intended to be bound by the original terms by presenting a properly executed original contract. The objective theory of contract formation as articulated in Smith v Hughes and Sonap Petroleum applies: if a party conducts himself in a manner that would lead a reasonable person to believe he is assenting to certain terms, he is bound by those terms regardless of his subjective intention. Written consent to amendments must be given by a person with actual authority to bind the creditor, and such consent must relate to amendments actually proposed at the time the consent is allegedly given.

The court did not make definitive credibility findings regarding the respondent's version of events (that he and Bergh had telephonically agreed to amendments and that the amended document was subsequently faxed), noting that the version was 'fraught with improbabilities' but that on the view taken of the matter, it was unnecessary to determine this issue. The court assumed without deciding that the respondent's version might be correct, but held that even on that assumption, the absence of written consent as required by clause 6 was fatal to his case. The court noted that the magistrate had made an error in relying on transmission data from the respondent's fax machine to determine when documents were sent, but this error was not material to the final outcome. The court also made an observation that the changed version regarding falsification of documents (initially put in cross-examination and then hastily withdrawn) reflected poorly on the credibility of the respondent's case, though this was not essential to the decision.

This case is significant in South African contract law and suretyship law for establishing important principles regarding: (1) the validity and enforcement of contractual clauses requiring written consent for variations to contracts, particularly suretyship agreements; (2) the application of the objective theory of contract formation (the doctrine of reasonable impression) to suretyship agreements; (3) the principle that when a party presents a duly executed contract to another party, a binding contract comes into existence at that moment; (4) the allocation of the onus of proof in disputes about contract variations - while the party relying on a contract must prove its terms, once a contract is established, the party alleging variation bears the onus of proving the variation was agreed to; (5) the strict interpretation of authority requirements in corporate contexts - only persons with actual authority can bind a company to contract variations. The case reinforces the sanctity of written contracts and the importance of compliance with contractual formalities, particularly in commercial contexts.
