Comwezi Security Services (Pty) Ltd v Cape Empowerment Trust Limited

The first appellant, Comwezi Security Services (Pty) Ltd (Comwezi), borrowed R4 million from the respondent, Cape Empowerment Trust Limited (CET). Repayment was secured by a cession and pledge of 20 shares in Comwezi held by the Grapsy Trust, represented by the second appellant, Mr Mowzer, as trustee. When the loan was not repaid on 30 April 2009 as agreed, the parties entered into a settlement agreement on 8 June 2010. The settlement provided that the loan would be discharged by issuing 25 shares in Comwezi to CET. The settlement agreement contained a resolutive condition requiring CET to conduct a due diligence investigation within three months. If the condition was not fulfilled, the settlement agreement would lapse and parties would revert to their positions under the loan agreement. CET was given the right to waive or 'relax' the resolutive condition. CET purported to extend the date for fulfillment 13 times, citing Comwezi's failure to cooperate with the investigation. Comwezi argued these extensions were invalid and that the settlement agreement had lapsed. The high court (Louw J) held the extensions were permissible and ordered Comwezi to cooperate with the investigation.

• Whether the power to 'relax' the resolutive condition in clause 10.3 of the settlement agreement entitled CET to extend the three-month time period for completing the due diligence investigation
• Whether multiple extensions of the time period were permissible or whether the power of relaxation could only be exercised once
• Whether the subsequent conduct of parties in implementing the agreement is admissible as evidence in interpreting the contract

The appeal was dismissed with costs, including the costs of two counsel where two counsel were employed. The high court order compelling Comwezi to cooperate with the due diligence investigation was upheld.

The binding legal principles established are: (1) In interpreting a contractual provision granting a power to 'relax' a resolutive condition, the court must consider the provision in context and give it operative effect consistent with the purpose of the contract; (2) Where a power to relax relates to a time-based condition, it necessarily includes the power to extend that time period; (3) Unless the contract clearly limits a power of extension to a single exercise, such power may be exercised multiple times as circumstances require; (4) Under the modern approach to contractual interpretation, the subsequent conduct of parties in implementing their agreement is admissible as contextual evidence to assist in determining the objective meaning of disputed provisions, regardless of whether ambiguity exists; (5) Where both parties have consistently implemented a contract on a particular interpretation, this provides strong evidence of how reasonable business people in their position would understand the disputed provision.

The court made several non-binding observations: (1) While subsequent conduct is admissible as context in interpretation, it cannot be used to give language a meaning that is otherwise impermissible—in such cases the conduct may be relevant to rectification or estoppel claims instead; (2) The court noted, without deciding, that Comwezi had not argued that the power of relaxation was subject to tacit limitations such as requirements of good faith or arbitrio boni viri, nor that CET had failed to exercise the power properly; (3) The court observed that allowing only a single extension would create a perverse incentive for CET to extend the period by an unreasonably lengthy time to ensure it captured all contingencies; (4) The court noted the public interest in certainty regarding share ownership where both Command Holdings Ltd and CET were listed on the JSE alternative board, though this did not ultimately affect the outcome.

This case is significant in South African contract law for several reasons: (1) It applies and reinforces the modern approach to contractual interpretation established in Natal Joint Municipal Pension Fund v Endumeni Municipality, emphasizing context over literal meaning; (2) It clarifies that interpretation must give effect to all words in a contract and cannot render provisions nugatory; (3) It establishes that the subsequent conduct of parties in implementing their agreement is admissible as context in interpretation, extending the previously narrow exception that applied only in cases of ambiguity; (4) It provides guidance on interpreting resolutive conditions and powers of waiver/relaxation in commercial agreements; (5) It demonstrates the court's preference for businesslike and sensible interpretations over technical or literal readings that would lead to uncommercial results.
