On 15 April 2002, Mr M I Mia (the purchaser) concluded a written agreement with a consortium of six persons (represented by the first appellant) to purchase a 100% member's interest in Odhin Investments CC (the second appellant) for R1,600,000. The CC was to own a penthouse unit in a sectional title scheme called 'Lazy Lizard' on the KwaZulu-Natal north coast. The purchase price was payable through a deposit of R50,000 and a balance of R1,550,000, secured by two bank guarantees: R250,000 (first guarantee) and R1,300,000 (second guarantee). Clause 20.2 stipulated that the first guarantee was to come from proceeds of the sale of Mr Mia's property at Umdloti, and clause 20.2.1 gave him 12 months to sell that property, after which both guarantees for the full purchase price had to be provided. Mr Mia paid only R25,000 of the deposit and his estate was sequestrated in October and November 2003. The respondents were appointed as trustees. They advised that they would proceed with the purchase and attempted to furnish guarantees. On 21 January 2004, the sellers' attorneys placed the respondents in mora for failure to deliver bank guarantees and gave them 14 days to remedy the breach. The respondents offered guarantees but with conditions that were unacceptable to the sellers. On 10 February 2004, the sellers cancelled the agreement. The respondents launched proceedings to declare the cancellation invalid.
The appeal was upheld with costs. The order of the High Court (Hurt J) was set aside. The plaintiffs' (respondents') claim was dismissed with costs, excluding costs occasioned by filing of certain additional affidavits, which were to be paid by the first defendant (first appellant).
The binding legal principles established are: (1) Where a contract stipulates that guarantees for the full purchase price must be provided upon expiry of a specified period, and the purchaser fails to furnish a first guarantee within that period, both guarantees become due immediately upon expiry of that period. (2) A seller is not obliged to define the form of an 'acceptable' guarantee before making demand for it; the purchaser must tender a guarantee in accordance with the contract terms, and the seller may accept or reject it, provided the seller exercises honest judgment (arbitrium boni viri). (3) Courts will enforce the actual written agreement signed by parties and will not give effect to unauthorized amendments made after signature, even where parties may have operated under a mutual misapprehension based on such amendments. (4) An integration clause (entire agreement clause) prevents unilateral alterations to a contract unless reduced to writing and signed by both parties. (5) Where guarantees are due and a purchaser fails to furnish them within the time allowed in a valid mora notice, the seller is entitled to cancel the agreement pursuant to the cancellation clause.
The Court made non-binding observations that: (1) The form of a guarantee in a written contract of sale will generally be ascertainable from the terms of the particular agreement, if not separately agreed upon by the parties, and parties may agree to amend the form. (2) Once a guarantee has been furnished, the seller will either accept or reject it, and if rejected, the seller will advise the basis of rejection, which may be challenged by the purchaser if unreasonable. (3) It would make no commercial sense for sellers to stipulate a time for delivery of a first guarantee but be content with no time being fixed for delivery of both guarantees in the event of failure to furnish the first guarantee. (4) The Court referenced the principle from Dharumpal Transport (Pty) Ltd v Dharumpal that a seller is not entitled to reject a proposed guarantor from pure caprice and must exercise honest judgment in deciding whether a proposed guarantor is sufficient and suitable.
This case is significant in South African contract law for establishing important principles regarding: (1) the interpretation of payment and security clauses in sale agreements, particularly where time periods are stipulated; (2) the seller's entitlement to cancel a contract for breach where the purchaser fails to furnish contractually required guarantees on the due date; (3) clarifying that where a contract provides for guarantees 'acceptable to' a party's attorney, the seller is not obliged to pre-define the acceptable form before making demand, but must exercise honest judgment (arbitrium boni viri) in accepting or rejecting guarantees tendered; (4) the principle that courts will enforce the actual written agreement between parties and will not give effect to unauthorized amendments made after signature, even where both parties may have operated under a misapprehension; and (5) the application of the integration clause (entire agreement clause) to prevent unilateral alterations to written contracts. The case reinforces the importance of clear drafting of payment terms and security provisions in sale agreements.
