An acceptance may be withdrawn if the withdrawal reaches the offeror before or at the same time as the acceptance would have become effective.
With respect to the withdrawal of an acceptance this Article lays down the same principle as that contained in Article 2.1.3 concerning the withdrawal of an offer, i.e. that the offeree may change its mind and withdraw the acceptance provided that the withdrawal reaches the offeror before or at the same time as the acceptance.
It should be noted that while the offeror is bound by the offer and may no longer change its mind once the offeree has dispatched the acceptance (see Article 2.1.4(1)), the offeree looses its freedom of choice only at a later stage, i.e. when the notice of acceptance reaches the offeror.
This Article corresponds to Article 22 CISG.
