A contract-law concept defining a formation element, enforceability rule, or negotiated term affecting obligations between parties. It governs formation, interpretation, performance, breach, or remedies by specifying conditions that must be satisfied or effects that follow. It does not apply where required assent, consideration, authority, or writing elements are absent when they are prerequisites. It materially determines whether obligations are enforceable and what remedies are available for nonperformance. The concept is generally stable, though statutory reforms and commercial practices may refine its application over time.

Principle

Revocation ordinarily restores the offeror's freedom to change intentions before acceptance; it is effective only when communicated to the offeree or when conditioned by the governing rule (e.g., not effective during a valid irrevocable period).

Demonstration

A contractor mails an offer to perform work and later sends a clear written notice withdrawing the proposal; the withdrawal terminates the offer as soon as the offeree receives the revocation, provided no exception like a firm offer exists.

Misapplication

Assuming revocation is effective at the time the offeror decides to revoke rather than when the offeree receives notice, leading to unfair outcomes where the offeree has already dispatched an acceptance.

Consequence

When properly effected, revocation ends negotiations and frees the offeror from contractual obligation; it also creates risk for the offeree who may have relied on the offer without protective measures.

Reversal

Reversal is the situation where the offer cannot be revoked—e.g., under a valid option contract or a firm offer—so the offeror remains bound to keep the offer open for the agreed period.

Boundary

Revocation applies to offers that are not otherwise rendered irrevocable; it does not include unilateral acts of the offeree, acceptance actions, or revocations that violate statutory or contractual exceptions.

Semantic Tension

Tension arises between revocation and the mailbox rule: revocation is effective upon receipt, while acceptance may be effective upon dispatch, producing a timing conflict when both messages cross in transit.

Synthesis

Revocation is the communicated withdrawal of an offer that, when received by the offeree and not blocked by an exception, terminates the offer and returns parties to pre-offer freedom to negotiate.
