Sentinel Mining Industry Retirement Fund v Waz Props (Pty) Ltd

Waz Props owned properties in Elton Hill, Johannesburg. SMIRF owned the Melrose Arch Development and wished to upgrade Park Road, Birnam, near Waz Props' properties. When Waz Props applied to rezone its properties, SMIRF lodged a merit-less objection aimed at pressuring Waz Props into contributing to SMIRF's upgrade project. SMIRF withdrew its objection when Waz Props entered into a contract agreeing to pay R115,531.87 towards the project. The contract provided three payment options: (1) immediate payment into an interest-bearing trust account; (2) provision of a bank guarantee; or (3) registration of a restrictive condition on the property title deeds. Waz Props chose option 2 and caused Werlex to have ABSA issue a guarantee. Clause 5 of the contract provided that if the project was not completed by 1 April 2009, funds paid under option 1 would be refunded and restrictive conditions under option 3 would be cancelled, but made no express provision for option 2. The project was not completed by 1 April 2009 but was completed on 15 February 2010. SMIRF's attorneys presented the guarantee for payment on 26 March 2010. Despite objection from Waz Props, ABSA paid R207,810.35 (the guarantee amount plus interest) to SMIRF's attorneys on 6 April 2010. Waz Props and Werlex sued for repayment.

• Whether clause 3 contained a primary payment obligation separate from the security provisions in clause 4
• Whether headings in contracts can be used as an aid to interpretation
• Whether clause 5 contained a resolutive condition that terminated the obligation to pay if the project was not completed by 1 April 2009
• Whether a tacit term should be incorporated into clause 5 to provide that the guarantee under option 2 would lapse if the project was not completed by 1 April 2009, similar to the express provisions for options 1 and 3
• What test should be applied for incorporating tacit terms into contracts

The appeal was dismissed with costs. The decision of Willis J in the South Gauteng High Court, Johannesburg, in favor of Waz Props and Werlex was upheld, meaning SMIRF and its attorneys were required to repay the amount paid under the guarantee.

The binding legal principles established are: (1) Headings in contracts can be taken into account in interpreting contracts, and where a heading and detailed provisions can be read together consistently, they should be; (2) Contracts must be read as a whole to ascertain the parties' intention, with all clauses considered together rather than in isolation; (3) A tacit term may be incorporated into a contract where necessary to give effect to the clear intention of the parties as evidenced by the express terms of the contract, even in detailed commercial contracts, particularly where failure to incorporate the term would produce an anomalous or commercially unreasonable result; (4) Where a contract provides for alternative methods of performance and includes express resolutive conditions for some but not all alternatives, a tacit term incorporating the same resolutive condition for the remaining alternative may be necessary where the parties' intention is clear from the contract as a whole and the "innocent bystander" test is satisfied.

The court made several non-binding observations: (1) It noted the difference between headings and marginal notes or other writing in contracts, suggesting that where a heading conflicts with the body of a contract, the body should prevail because parties' intentions are more likely to appear from detailed provisions than abbreviations; (2) The court distinguished the case from situations involving delayed completion of construction commissioned by the party seeking completion; (3) The court declined to find that the applicants' failure to request return of the guarantee after 1 April 2009 evidenced an interpretation inconsistent with their case, noting this conduct was equally consistent with lax administration or belief that SMIRF would not act in bad faith; (4) The court noted that the case was not appropriate for reconsidering the correctness of the majority judgment in Dormell Properties 282 CC v Renasa Insurance Co Ltd & others NNO 2011 (1) SA 70 (SCA) since it was common cause that ABSA was obliged to make payment under the guarantee; (5) The court observed that there was no dispute of fact merely because the parties disagreed on whether a tacit term should be inferred, since the facts from which the inference was to be drawn were common cause.

This case is significant for South African contract law as it clarifies important principles regarding contract interpretation and the incorporation of tacit terms. It establishes that headings in contracts can be used as aids to interpretation when they can be read consistently with the detailed provisions. It demonstrates that courts should read contracts as a whole to ascertain the parties' true intentions. The case also addresses the rigorous test for incorporating tacit terms, particularly in detailed commercial contracts, while recognizing that where express terms reveal a clear pattern or scheme, tacit terms may be necessary to give effect to the parties' obvious intention and avoid anomalous results. It reinforces that the court must be satisfied that incorporation of a tacit term is necessary, not merely reasonable, but shows this test can be met where the alternative interpretation produces illogical or commercially unreasonable results.
