Nedcor Bank Limited v SDR Investment Holdings Co (Pty) Ltd and Others

Nedcor Bank lent money to the respondents (SDR Investment Holdings and related entities), secured by mortgage bonds over three wine farms in Stellenbosch (Zorgvliet, Le Pommier and Springgrove). When the debt was not repaid, the bank instituted enforcement action and liquidation proceedings. On 14 November 2001, the parties entered into a settlement agreement (made an order of court) that postponed liquidation and gave the respondents until 6 December 2001 to sell the properties and repay the debt of R12,778,225.14. If the debt remained unpaid by 14 January 2002, the bank was authorized to sell the properties by public auction without reserve. No sale materialized by the deadline. In February 2002, the bank received offers from Haskell (an American businessman) totaling R20 million for the three farms, which Rymer (controlling mind of respondents) rejected, insisting on a public auction. The bank advertised an auction for 12 March 2002 to sell all three farms as one. On 8 March 2002, Rymer accepted an offer of R18 million for Zorgvliet alone from Bunker's Hill Investments (obtained by Haskell). The bank refused to cancel or postpone the auction. The respondents' urgent application to stop the auction was dismissed. At the auction on 12 March 2002, all three farms were sold for R31 million. Representatives of Haskell/Bunker's Hill stopped bidding at R30 million. The bank accepted the R31 million offer that same afternoon. The respondents sued for damages claiming the bank breached implied/tacit terms of the agreement.

• Whether implied or tacit terms can be imported into a contract that conflict with valid express provisions
• Whether the bank owed duties of good faith, skill and diligence, and to procure the highest price when exercising its contractual rights to sell properties
• Whether the bank's discretion under the agreement had to be exercised arbitrio boni viri (with the judgment of a fair-minded person)
• Whether the bank acted with improper motive in accepting the highest bid on the afternoon of the auction
• Whether the auctioneer's commission paid by the bank was reasonable

The appeal was upheld with costs. The order of the court below was replaced with: (1) Judgment for the respondents in the amount of R93,986.65; (2) Interest on R93,986.65 at 15.5% per annum from 27 April 2002 until final payment; (3) The appellant to pay 20% of the respondents' costs in the court below.

Implied or tacit terms will not be imported into a contract where they conflict with valid express provisions of that contract. Implied terms are standardized provisions imposed by law and do not normally apply if in conflict with express contractual terms. Tacit terms are inferred from the common intention of parties derived from express terms and surrounding circumstances, and it is unlikely that a term contrary to valid express terms would be inferred. When parties enter into a valid agreement with express terms, those terms govern their relationship and the courts will enforce them, subject only to requirements of good faith in performance. The principle requiring discretion to be exercised arbitrio boni viri applies only where a contracting party has the right to decide the prestation of the other contracting party, not where a creditor is exercising expressly conferred contractual rights to enforce a debt.

The court made observations about the principle of bona fides (good faith) that underlies and informs South African contract law, noting that while this principle is fundamental, there was nothing to suggest the parties were not acting in good faith when entering into or performing the contract. The court also commented on general industry standards for auctioneer's commission, noting that between 2% and 7.5% (with 5% being fair and reasonable) or up to 10% is generally regarded as acceptable in the industry for the sale of immovables at auction. The court distinguished the facts from cases involving movables held in pledge, citing Bock v Duburoro Investments (Pty) Ltd 2004 (2) SA 242 (SCA) and Iscor Housing Utility Co v Chief Registrar of Deeds 1971 (1) SA 613 (T). The court also observed that the respondents' construction of the agreement as appointing the bank as their agent to act in their best interests was untenable given that the bank was a judgment creditor exercising rights in lieu of executing a warrant of execution.

This case is significant in South African contract law for establishing clear principles regarding the relationship between express and implied/tacit terms in contracts. It confirms that courts will not imply terms, whether as a matter of law (implied terms) or inferred intention (tacit terms), that conflict with valid express contractual provisions. The judgment reinforces the principle that parties are bound by their express agreements and that good faith, while underlying contract law, does not override clear contractual rights. The case also clarifies the limited application of the arbitrio boni viri principle to situations where one party has discretion to determine the other's prestation, distinguishing this from situations where a creditor exercises expressly conferred contractual rights. It provides important guidance on the enforcement of settlement agreements and the exercise of creditors' rights under such agreements, particularly in the context of auction sales of secured property.
