The appellant operated hotels in sectional title complexes using a rental pool system. Owners of units participated in the pool and shared income after deductions for levies, management fees, and operating costs. The respondent owned 50 residential units and 12 commercial units in the ICON building in Cape Town. The appellant was keen to obtain the respondent's units and superior reception area for its rental pool. On 31 March 2011, the parties entered into a Memorandum of Understanding (MOU) for the period 1 April 2011 to 31 January 2012. The MOU provided for a fixed levy rate of R1,250 per unit and a management fee of 14% of turnover. Clause 4.3 stated "No other expense or payment would be allowed" except by written agreement. The MOU was different from the appellant's standard agreement which provided for deduction of variable operating costs. The MOU terminated on 29 February 2012. In March 2012, the respondent discovered the appellant had deducted operating costs totaling R2,248,156.29 over the contract period. The respondent claimed repayment of this amount.
The appeal was dismissed with costs including the costs of two counsel. The High Court order requiring the appellant to pay R2,248,156.29 plus interest and costs to the respondent was upheld.
The binding legal principles established are: (1) Clear and express terms of a contract cannot be altered by contextual evidence of how the parties implemented the contract. (2) Where contractual language clearly and expressly excludes a particular liability or obligation, no tacit term can be implied to the contrary, particularly where the parties have deliberately applied their minds to that subject matter. (3) Evidence of subsequent conduct may be considered as part of the contextual setting for interpreting a contract, but only if: (a) it is indicative of a common understanding of the terms; (b) it is used as an aid to interpretation and not to alter the words used; and (c) it is used as conservatively as possible. (4) A complete and efficacious contract leaves no room for implying additional terms. (5) The requirement in clause 6.2 for variations to be in writing and agreed by all parties reinforced that no unilateral conduct or practice could vary the express terms.
The court noted that the respondent was in a strong bargaining position during negotiations, which provided context for understanding why the MOU departed significantly from the appellant's standard agreement. The court also observed that the failure to detect impermissible deductions may have been due to simple mistake or misunderstanding, rather than acceptance of liability. Van der Merwe JA cited the well-established principle from Novartis SA (Pty) Ltd v Maphil Trading (Pty) Ltd that the meaning of a contract must be ascertained by consideration of the words used, the contract as a whole, and the context or factual matrix, irrespective of whether there is ambiguity. The court also referenced the caution from KPMG Chartered Accountants (SA) v Securefin Ltd that contextual evidence must be used "as conservatively as possible." The court noted that Mr Carrim's evidence that he was unaware of the deductions before March 2012 could not be rejected.
This case is significant in South African contract law as it reinforces important principles of contractual interpretation. It demonstrates that: (1) clear and express contractual terms cannot be altered or contradicted by contextual evidence or subsequent conduct; (2) the modern contextual approach to interpretation does not permit courts to rewrite contracts or add terms where the language is clear; (3) evidence of subsequent conduct must be used conservatively and only as an aid to interpretation, not to alter the words used by the parties; (4) for a tacit term to be implied, the contract must be incomplete or inefficacious on the subject matter, and the officious bystander test must be satisfied; and (5) where parties have deliberately addressed a matter in their contract and made express provision for it, there is no room for implying a contrary term. The case provides important guidance on the limits of contextual interpretation and the primacy of express contractual language.
