REVOCATION OF AN OFFER – CISG ARTICLE 16(1)
Article 16 CISG of the U.N. Convention on Contracts for the International Sale of Goods (the Convention) and Article 2:202 of the Principles of European Contract Law (PECL) deal whether an offer is binding and when it is irrevocable.
Both the Convention and the PECL distinguish between the revocation of an offer and the withdrawal of an offer. In the Convention, revocation of an offer that has reached the offeree and is effective is regulated by Article 16; withdrawal of an offer that has not yet reached the offeree is regulated by Article 15(2).
Similarly, under the PECL, an offer becomes effective when it reaches the offeree (Article 1:303(2) and (6)), and a subsequent revocation of the offer is regulated by PECL Article 2:202. However, the offer may be withdrawn before it reaches the offeree. In that situation, it will not become effective (PECL Article 1:303(5)).
There is divergence in the way in which different legal systems deal with the matter of revocation of an offer. In common law systems, the offeror, in the absence of consideration given by the offeree, has been granted the freedom to revoke the offer before the contract is concluded (e.g., in the case of written assent, before the offeree dispatches the acceptance), thus weakening the binding force of an offer.
