Offer and Acceptance
Offer and Acceptance
1. Introduction to Contract Formation
A contract is formed when parties reach agreement on all material terms. This is typically analyzed through the two-part process of offer and acceptance.
2. The Offer
In simple words, an offer is a proposal to enter into a contract. It is a statement made by one person (the offeror) to another (the offeree) that clearly explains the deal they are prepared to make and the terms they are willing to follow.
• Requirements for a Valid Offer:
A. Firm Intention: Must be made with a serious intention to be bound (animus contrahendi).
B. Complete: It must contain all material terms; "nothing is agreed until everything is agreed".
C. Clear and Certain: The offer must be clear enough that a simple "yes" creates a contract. Case: Mouton v Hanekom (an offer to perform when financial position allows is not too vague).
D. Plain Language: Under the Consumer Protection Act (CPA) , offers to consumers must be in plain and understandable language.
• Offers to the Public:
◦ Advertisements: Generally regarded as invitations to do business (invitatio ad offerendum) rather than binding offers. Case: Crawley v Rex
◦ Rewards: Can constitute a valid offer to the public if the advertiser intends to be bound by the offeree's performance. Bloom v American Swiss Watch Co.
◦ Tenders: Usually an invitation to elicit offers from others .
◦ Auctions:
▪ Simple Auction: The bidder makes the offer; the auctioneer accepts or rejects.
▪ With Reserve: The auctioneer invites offers; notice of reserve must be given in advance .
▪ Without Reserve: The auctioneer makes the offer to sell to the highest bidder .
• Termination of an Offer:
◦ Rejection or Counter-offer.
◦ Death of either party (unless an option contract exists).
◦ Effluxion of time (lapse after a prescribed or "reasonable" time) .
◦ Revocation (withdrawal before acceptance).
◦ Loss of legal capacity to act.
◦ Acceptance (which terminates the offer and creates the contract).
3. The Acceptance
In simple words, acceptance is saying "yes" to the offer exactly as it was made. It is a clear and unambiguous statement by the offeree that they agree to every single part of the proposal.
• Requirements for Valid Acceptance:
1. Unqualified and Complete: known as the "Mirror Image Rule," this requirement states that the offeree must agree to every element of the offer—nothing more and nothing less.
A. Authorized Person: Must be made by the person to whom the offer was addressed.
B. Conscious Response: One cannot accept an offer they are unaware of. Bloom v American Swiss Watch Co, a person provided information that led to the arrest of jewel thieves but was unaware that a reward had been offered at the time. The court ruled he could not claim the reward because his mind had not met with the offeror's mind—there was no concursus animorum.
A. Prescribed Form: Must follow any specific mode of acceptance required by the offeror.
• When and Where Acceptance Takes Effect:
◦ Inter praesentes (Parties present): Acceptance is effective immediately.
◦ Inter absentes (Parties distant):
Four theories apply:
a. Information Theory (General Rule): The contract is concluded only when and where the offeror learns of the acceptance.
b. Expedition Theory (The Postal Rule): For postal contracts, the deal is closed the moment the letter is posted.
c. Declaration Theory: When the offeree signs or writes the acceptance.
d. Reception Theory: When the acceptance reaches the offeror's address. This applies to electronic contracts (email, SMS) under the ECTA .
4. Ancillary Agreements (Pacta de Contrahendo)
A pactum de contrahendo is a "contract about contracting"—an agreement aimed at concluding another contract in the future.
• Option Contracts:
An agreement where the offeror binds themselves to keep an offer open for a certain period.
◦ Nature: It consists of two offers—the main offer (e.g., to sell land) and the offer of the option itself.
◦ Legal Effect: The offer becomes irrevocable.
◦ Formalities: Generally must follow the same formalities required for the main contract.
◦ Remedies for Breach: Damages measured by "positive interest" (expectation loss) or an interdict.
• Preference Contracts (Right of Pre-emption):
The grantor binds themselves to give the grantee preference if they ever decide to conclude a specific contract (usually a sale).
◦ Nature: A negative obligation not to alienate property to a third party without first offering it to the grantee.
◦ Remedies (The Oryx Mechanism): If the grantor sells to a third party in breach of the right, the grantee can "step into the shoes" of the buyer. Case: Associated SA Bakeries (Pty) Ltd v Oryx & Vereinigte Bäckereien (Pty) Ltd .
◦ Land Sales: The Constitutional Court in Mokone v Tassos Properties CC overruled earlier views, holding that pre-emptive rights for land sales do not necessarily need to comply with the same statutory formalities as the sale itself.
