Byrne v Van Tienhoven (1880) established the principle that a revocation of an offer is only effective when communicated. The court held that an un-communicated revocation sent by post does not terminate the offer, reinforcing clarity in acceptance and revocation rules in agreements.
Communication of Revocation: A revocation of an offer must be communicated to the offeree to be effective. Simply posting a letter of withdrawal is insufficient if it has not been received. This principle ensures that an offeror cannot revoke silently without notifying the other party.
