On 3 April 2017, the appellants and respondents concluded a Sale of Shares Agreement (SoS agreement) for R50 million payable in tranches. Clause 3.1 contained suspensive conditions including that the purchaser (Mr Segoale) must cede a life insurance policy worth R15 million on or before the effective date of 21 June 2017. Clause 3.4 provided that if any suspensive condition was not timeously fulfilled, the entire agreement would be of no force or effect. By 21 June 2017, the suspensive conditions had not been fulfilled, causing the SoS agreement to lapse ex lege. However, the parties continued to act under the mistaken belief that the agreement remained valid. On 20 February 2019, disputes arose and the parties concluded an arbitration agreement which purported to amend clause 22 of the SoS agreement and appointed a retired judge as arbitrator. Arbitration proceedings were conducted and an award was issued. The appellants then approached the high court seeking declarations that the arbitration agreement and award were nullities because the SoS agreement upon which they were predicated had lapsed. The high court dismissed the application, finding that the arbitration agreement was a self-standing agreement that survived the lapsing of the SoS agreement.
The appeal was upheld with costs. The high court order was set aside and replaced with declarations that: (a) the arbitration contract was a nullity; (b) the appointment of the arbitrator was a nullity; (c) the arbitration proceedings and award dated 10 May 2021 were a nullity; and (d) costs were to be paid by the second and third respondents.
Where a contract containing a suspensive condition is not timeously fulfilled and becomes void ab initio, all clauses in that contract, including arbitration clauses, fall with it. An arbitration agreement that is predicated on and dependent upon the existence and validity of a main agreement cannot survive as a self-standing agreement when the main agreement has lapsed due to non-fulfilment of suspensive conditions. Where parties expressly agree that multiple commercial agreements constitute 'a single and indivisible transaction', the lapsing of the main agreement due to non-fulfilment of conditions precedent renders all related agreements void, including any subsequent arbitration agreement purporting to amend the dispute resolution clause. An arbitration clause embedded in a void contract cannot operate because the clause itself is also void - a party denying that a contract ever came into existence is thereby denying that they ever joined in the arbitration submission.
The Court observed that it would be 'unbusiness-like' for commercial parties to agree to a single composite agreement comprising multiple agreements subject to one suspensive condition, yet intend for some agreements to continue when one falls through. The Court noted that the arbitrator exceeded his mandate by going beyond what the parties expressly referred to him for arbitration, and that his decision was ultra vires. The Court commented that the respondents were 'evidently latching on this technicality' of the arbitrator's purported decision while being well aware of what the parties actually intended. The Court emphasized that interpretation must not construct contracts in piecemeal fashion but as a whole, particularly where there is no ambiguity in meaning, and that courts cannot disregard the context and language of agreements which parties intended to be bound by.
This case establishes important principles regarding the interpretation of composite commercial agreements and the fate of arbitration clauses when the underlying contract is void. It reinforces the principle that arbitration agreements do not survive when the main contract is void ab initio due to non-fulfilment of suspensive conditions. The judgment emphasizes that courts must interpret commercial agreements holistically, giving effect to the parties' clear intention as expressed through the language and structure of their agreements. It confirms that where parties structure their commercial relationship as 'a single and indivisible transaction', all component agreements stand or fall together. The case also demonstrates the limits of the separability doctrine for arbitration clauses - they cannot be construed as self-standing where the text, context and purpose indicate they were wholly dependent on the main agreement. This is significant for commercial parties structuring complex transactions with multiple interrelated agreements subject to conditions precedent.
