Frederick Kern, an American expert in creating systems for yellow pages telephone directory entries, was resident in California when he concluded a contract with Telkom Directory Services (Pty) Ltd (TDS) in November 1998. TDS's managing director, Ms Sheasby, met Kern at a conference in Florida in October 1998 and engaged him to provide services to TDS for a project merging yellow pages and white pages databases. They concluded a Master Consulting Agreement on 3 November 1998, governed by California law, which provided for a termination clause allowing either party to terminate on 30 days' written notice. A 'work order' was concluded on 18 January 1999 and extended twice (September 1999 and June 2000), which stated that once both parties signed a Work Order for a subsequent stage, they were 'both bound to fulfil the time and monetary obligations of the Work Order'. On 13 March 2001, TDS purported to terminate the agreement giving 30 days' notice. Kern claimed this was a breach, arguing the work order superseded the termination clause. Kern claimed damages of approximately R6 million.
The appeal was upheld with costs. The order of the high court was set aside and replaced with an order dismissing the plaintiff's (Kern's) claim with costs, including those of the plaintiff's expert witness, Mr Meredith, who was declared a necessary witness.
Under Californian law, extrinsic evidence of parties' intentions in contractual interpretation is admissible only if the language of the contract is reasonably susceptible to the meaning contended for by the party seeking to rely on such evidence. A contract must be interpreted to give effect to all its provisions and none should be rendered meaningless. Where a work order is expressly stated to be an integral part of a master agreement and subject to termination 'as provided in the Master Consulting Agreement', the termination clause in the master agreement continues to operate unless the work order contains clear language excluding that right. The unexpressed subjective beliefs of individual negotiators, even if shared, do not constitute mutual intention where such understanding contradicts the express terms of the written contract and was not communicated to all contracting parties.
The court noted that neither Kern nor Sheasby showed that their understanding regarding the exclusion of the termination clause had been conveyed to anyone else at TDS, including its board of directors. The court also observed that the witnesses 'did not explain coherently how the termination clause fitted in with their understanding of the contract'. The court emphasized that the principle that the mutual (shared) intention of the parties must be given effect requires more than the subjective beliefs of individual negotiators - it requires evidence that such understanding was actually mutual and known to the contracting parties.
This case is significant for its application and clarification of how South African courts should approach the interpretation of contracts governed by foreign law, specifically Californian law. It demonstrates the limits of extrinsic evidence in contractual interpretation even under a legal system more permissive than South African law. The case reinforces the principle that even when extrinsic evidence is provisionally admissible, the contract language must be 'reasonably susceptible' to the interpretation contended for before such evidence can be given effect. It emphasizes that all provisions of a contract must be given effect and that interpretation should not render any clause meaningless. The case also illustrates the importance of ensuring that subjective intentions of individual negotiators are reflected in the written contract and communicated to all parties (including corporate decision-makers) for such intentions to constitute mutual intention enforceable under the contract.
