Geldenhuys NO and others v Daniels

On 11 January 2008, the Hannes Geldenhuys Trust (represented by the appellants as trustees) made a written offer to purchase immovable property from Ms Susan Romao-Duarte Daniels for R1,570,000. Clause 15 of the offer stated that the offer was "irrevocable until 24h00 on 18 January 2008" and binding upon acceptance prior thereto. Ms Daniels accepted the offer on 29 January 2008, after the stated irrevocable date had passed, and notified the Trust of her acceptance. The Trust took occupation, paid occupational rental, commenced major renovations, signed transfer documents and paid transfer costs. When rates clearance was sought, a building plan problem was discovered - a braai area was built 300mm over the building line. Ms Daniels instructed an architect to obtain a relaxation from the municipality, which would take approximately two months. The Trust then lost interest and repudiated the agreement in August 2008. Ms Daniels accepted the repudiation and sued for damages representing the difference between the Trust's purchase price and the price at which she subsequently sold the property to a third party (R328,835).

• Whether an offer that is stated to be irrevocable until a specified date lapses automatically after that date passes, or merely becomes revocable
• Whether acceptance of an offer after the expiry of an irrevocable period, but before revocation, results in a binding contract
• The proper approach to interpreting headings in contracts when they conflict with the body of the contractual clause

The appeal was dismissed with costs.

Where an offer is stated to be "irrevocable" until a specified date but contains no provision that it will lapse if not accepted by that date, the legal effect of the date passing is that the offer becomes revocable rather than lapsing automatically. The offer remains capable of acceptance until it is actually revoked by the offeror. Acceptance after the irrevocable period but before revocation creates a binding contract. Where a heading in a contract conflicts with the body of the contractual provision, the body prevails because the parties' intention is more likely to appear from the detailed provisions they have spelled out than from an abbreviation chosen to identify the effect of those provisions.

The court observed that it was surprising the parties did not agree on a stated case in terms of Rule 8(8)(a) given the uncomplicated and largely common cause facts, instead of burdening the court with unnecessary documents. The court also noted that there was no suggestion that the 18-day period between the offer and acceptance was unreasonable, though this was not essential to the decision as the offer had not been revoked regardless of reasonableness.

This case provides important clarification in South African contract law regarding the legal effect of an irrevocable offer period expiring. It establishes that an offer stated to be irrevocable until a specified date does not automatically lapse when that date passes unless the clause expressly states it will lapse. Instead, the offer merely becomes revocable and remains open for acceptance until actually revoked by the offeror. This is a significant principle for property transactions and commercial contracts generally. The case also reinforces the interpretive principle that the substantive provisions of a contract prevail over headings when they conflict, applying the approach in Sentinel Mining Industry Retirement Fund v Waz Props and the contextual interpretation approach in Natal Joint Municipal Pension Fund v Endumeni Municipality.
