Summary
THE MIRROR IMAGE RULE AND MODIFIED ACCEPTANCE
An acceptance must coincide with each and every term of an offer in order to conclude a contract (see Articles 19(1) CISG and 2:208(1) PECL). This requirement is known as the “mirror image rule” because the acceptance must be the very reflection of the offer, as in a mirror. An exception is established for the possible introduction of new terms into the acceptance that do not substantially alter the offer. In that case, the acceptance will be valid; the contract will consist of both the terms of the offer and those included in the acceptance that do not substantially alter the offer, so long as the offeror without delay does not object to the new terms (Articles 19(2) CISG and 2:208(3)(b) PECL), or the offer does not expressly limit acceptance to the terms of the offer (Article 2:208(1) PECL), or the offeree does not make his acceptance conditional upon the offeror's assent to the additional or different terms and the assent reaches the offeree within a reasonable time (Article 2:208(3)(c) PECL).
On the other hand, if an element that is included in the acceptance adds new terms, modifies the terms of the offer, or introduces any other type of limitation to the offer that substantially alters it, the contract will not be considered concluded; the response to the offer will be regarded as a counter-offer – that is, if it meets all requirements under the CISG or the PECL to be considered an offer in and of itself (see Articles 14 CISG and 2:208(1) PECL).
