Contract and Suspensive Conditions.

The decision in Close Trade 200074 CC t/a Ilcor Engineering Services v Crossmoor Transport (Pty) Ltd illustrates the important distinction between an ordinary contractual obligation and a suspensive condition. The case concerned agreements for the manufacture of specialised trailers and the effect of payment-security provisions contained in those agreements.

The contracts required Crossmoor to provide either a deposit or a guarantee from its financing institution before Ilcor began manufacturing. Ilcor nevertheless completed two trailers without receiving the required guarantee and began manufacturing a five-axle trailer without receiving the 50% deposit. Crossmoor knew that manufacture had started and did not object. When Crossmoor later failed to pay for or accept the trailers, Ilcor treated this conduct as repudiation and sold the completed trailers to reduce its loss.

The central legal question was whether the payment provisions prevented the contracts from becoming enforceable until the required security had been provided. The Supreme Court of Appeal held that they did not. A suspensive condition postpones the operation or enforceability of a contract until a specified future event occurs. Such a condition usually requires clear language showing that the agreement is “subject to” the event or will have no effect if it does not occur.

In this case, the provisions were intended to protect Ilcor before it incurred manufacturing costs. They gave Ilcor the right to withhold performance until the deposit or guarantee was supplied. However, they did not state that the contracts would be invalid or unenforceable without that security. Ilcor could therefore waive the protection and proceed with manufacture.

The parties’ previous dealings also supported this interpretation. Ilcor had manufactured trailers before receiving deposits, and Crossmoor had previously paid after completion. Its knowledge that production had begun further indicated that the agreements remained operative.

The Court correctly distinguished a contractual timing requirement from a suspensive condition. Ilcor’s failure to insist on security did not destroy the contracts. The appeal was accordingly upheld, and Ilcor’s damages claims remained enforceable.
