Revocation of Offer CASES

In English law, revocation of offer refers to the withdrawal of an offer by the offeror before it has been accepted, preventing contract formation.

Definition and Principles

An offer can generally be revoked at any time before acceptance, but this revocation must be clearly communicated to the offeree. Revocation only takes effect once the offeree actually receives and understands it. Merely posting a withdrawal is insufficient; the offer remains open until properly communicated.

Requirements for Valid Revocation

• Communication: Revocation must be directly or indirectly communicated and effectively understood by the offeree.
• Timing: Must occur before acceptance has taken place.
• Reliability: The offeree must reasonably understand that the offer has been withdrawn.

Case Example: Byrne & Co v Leon Van Tienhoven & Co (1880)

Van Tienhoven sent an offer by post from Cardiff to New York. Before Byrne received it, he posted an acceptance. Meanwhile, Van Tienhoven had posted a withdrawal. The withdrawal arrived after Byrne’s acceptance. The court held that a contract formed upon Byrne’s acceptance because the revocation was not effectively communicated beforehand.

Exceptions

• Firm Offers: Offers made irrevocable for a specified time.
• Option Contracts: Offers kept open through separate consideration.

Practical Importance

Clear rules on revocation provide commercial certainty and fairness, enabling parties to manage contractual risks effectively. Always use clear, direct, and prompt communication for revocations to avoid uncertainty.

Practical Takeaways

• Ensure revocations are clearly communicated and effectively received—preferably through instantaneous or direct methods.
• Avoid assuming an offer has been withdrawn merely because a revocation was posted.
• Consider specifying methods of communication or timing clearly in contracts to prevent confusion.
