Mutual & Federal Insurance Company Limited and Another v KNS Construction (Pty) Limited (In Liquidation) and Another

In 2011, SANRAL awarded KNS Construction a road construction contract at Ballito interchange, KwaZulu-Natal. On 22 March 2011, KNS Construction appointed Aqua Transport & Plant Hire as a sub-contractor. Aqua was required to provide a performance guarantee worth 15% of the main contract value (R3,423,850.49), which Mutual & Federal issued on 5 April 2011. The guarantee was issued for the due fulfilment by Aqua of its obligations to KNS Construction. By September 2011, KNS Construction experienced severe financial difficulties, ceased operations due to inability to pay suppliers and staff, and placed itself under voluntary winding-up on 13 December 2011. The site was closed by 14 December 2011. Despite its own financial collapse and inability to perform, KNS Construction purported to cancel the sub-contract on 14 December 2011 and demanded payment under the guarantee, alleging Aqua's failure to commence, proceed with or complete the project. KNS Construction was placed under provisional liquidation on 24 January 2012, made final on 5 March 2012. Liquidators continued to demand payment under the guarantee. Aqua obtained an interdict preventing Mutual & Federal from making payment pending determination of the dispute.

• Whether the performance guarantee was a 'call' or 'on demand' guarantee or a 'conditional guarantee' akin to suretyship
• Whether the guarantee was inextricably linked to the underlying sub-contract
• Whether payment under the guarantee was properly demanded given the circumstances
• Whether the demand for payment was made in bad faith or tainted by fraud
• The proper interpretation of performance guarantees in construction contracts

1. The appeals of the first and second appellants are upheld. 2. The respondents are declared liable, jointly and severally, for the costs of the appeal, including the costs of two counsel where so employed. 3. The cross appeal of the first respondent is dismissed with costs, including the costs of two counsel where so employed. 4. The order of the court a quo is set aside and replaced with: (a) The application is dismissed. (b) The first and second applicants are ordered to pay the respondents' costs, jointly and severally, including the costs of two counsel.

A performance guarantee is a conditional guarantee akin to suretyship (and not an autonomous 'call' or 'on demand' guarantee) where: (1) it uses language indicating it is issued for 'due fulfilment' or 'due and faithful performance' of the principal's contractual obligations; (2) payment is expressly made conditional on specific breaches of the underlying contract (such as failure to commence, proceed with, or complete work in accordance with the contract); (3) the guarantee is to be returned upon completion of the contract obligations; and (4) the guarantee is inextricably linked to the underlying contract rather than creating an independent payment obligation. Even where the guarantee gives the beneficiary discretion to demand payment, this does not convert it into an autonomous guarantee if the other factors indicate an accessory obligation. Such discretion must be exercised in good faith (arbitrio bono viri), and the specified trigger events (breach by the principal) must actually occur before payment becomes due. A demand for payment under such a guarantee cannot succeed where the conditions for payment are not met, particularly where the party demanding payment has itself failed to perform its own contractual obligations that would enable the principal to perform.

The court observed that even if the guarantee had been found to be a 'call' or 'on demand' guarantee, there would have been grounds to find fraud or misrepresentation on the part of KNS Construction. The court noted that KNS Construction's demand for payment under the guarantee, made while it was in dire financial difficulties, after placing itself in voluntary liquidation, and knowing that it would not be able to fulfil its own obligations under the sub-contract with Aqua, constituted misrepresentation. This observation suggests that even autonomous guarantees may not be enforceable where the demand is made fraudulently or in bad faith, particularly where the beneficiary knows it has itself breached the underlying contract and prevented the principal from performing. However, as this was not necessary for the decision, the court did not fully develop this point.

This case provides important guidance on distinguishing between autonomous 'call' or 'on demand' guarantees and conditional guarantees akin to suretyship in the South African construction industry context. It clarifies that the mere inclusion of discretionary language does not transform a conditional guarantee into an autonomous one. The court emphasized that the language, purpose, and terms of the guarantee must be examined holistically to determine the parties' true intention. The case reinforces that where a guarantee is issued for 'due fulfilment' or 'due and faithful performance' of contractual obligations, and payment is conditional on breach of the underlying contract, it creates an accessory obligation similar to suretyship rather than an independent payment obligation. This has significant implications for construction contracts, performance bonds, and the rights and obligations of parties in contractor/sub-contractor relationships. The case also confirms that the discretion to call on a guarantee must be exercised in good faith (arbitrio bono viri) and that demands made when the principal contractor itself is in breach or unable to perform may constitute misrepresentation.
