1. U.N. Conference on Contracts for the International Sale of Goods, Final Act (April 10, 1980), U.N. DOC. A/CONF. 97/18 reprinted in S.Treaty Doc. No. 98-9, 98th Cong., 1st Sess. and 17 INT'L LEGAL MAT. 668 (1980) [hereinafter "CISG" or "Convention"].

2. See Journal of Law & Commerce CISG Contracting States and Declarations Tables, 12 J.L. & Com. 283 (1993) for an updated list of Contracting States to the Convention.

3. Article 1(1) of the Sales Convention provides that:

This Convention applies to contracts of sale of goods between parties whose places of business are in different States:

(a) when the States are Contracting States; or

(b) when the rules of private international law lead to the application of the law of a Contracting State.

U.S. ratification of the Convention was accompanied by a declaration that the U.S. would not be bound by Article 1(1)(b).

4. CISG art. 7(1). Identical language was contained in Article 6 of the 1978 Draft of the Convention, to which the following commentary was appended:

National rules on the law of sales of goods are subject to sharp divergences in approach and concept. Thus, it is especially important to avoid differing constructions of the provisions of this Convention by national courts, each dependent upon the concepts used in the legal system of the country of the forum. To this end, Article 6 emphasizes the importance, in the interpretation and application of the provisions of the Convention, of having due regard for the international charachter of the Convention and for the need to promote uniformity.
Commentary on they Draft Convention on Contracts for the International Sale of Goods, Prepared by the Secretariat, art. 6 para. 1, U.N. Doc. A/Conf.97/5 (1979), reprinted in JOHN HONNOLD, DOCUMENTARY HISTORY OF THE UNIFORM LAW FOR INTERNATIONAL SALES 404, 407-08 (1989).

5. For a discussion concluding that, in regard to CISG, "foreign decisions on point must be accorded considerable weight in United States courts," see V. Susanne Cook, Note, The Need for Uniform Interpretation of the 1980 United Nations Convention on Contracts for the International Sale of Goods, 50 U. Pitt. L. Rev. 197, 226 (1988).

6. 789 F. Supp. 1229 (S.D.N.Y. 1992), appeal dismiss[e]d, 984 F.2d 58 (2d Cir. 1993).

7. Id.

8. 330 U.N.T.S. 38 (1959), No. 4739, 21 U.S.T. 2517, T.I.A.S. No. 6997, done at New York June 10, 1958. The Convention was implemented in the United States through Pub. L. 91-368, 84 Stat. 692, 9 U.S.C. § 201 (1970). The text of the Convention appears in 9 U.S.C.A. (West 1970 & Supp. 1992) immediately following § 201.

9. In the end, the court decided that the applicable federal law - CISG - was part of every state’s law. 789 F. Supp. at 1237 n.5. It is thus unclear whether the decision to apply a federal rather than state law of contract formation had any effect on the outcome of the case or even whether this discussion is properly considered part of the holding.

10.Id. at 1237. The UNIFORM COMMERCIAL CODE, U.C.C. § 1-101 et seq . (1987), 1-3A U.L.A. 3 ff. (1990) [hereinafter "U.C.C."].

11. For a critique of this aspect of the court's reasoning see infra text accompanying note 39.

12. For a more extensive treatment of this subject see John E. Murray, Jr., An Essay on the Formation of Contracts and Related Matters Under the United Nations Convention on Contracts for the International Sale of Goods, 8 J.L. & Com. 11 (1988).

13. Perhaps the most infamous example of the mirror-image rule in perverse action is Poel v. Brunswick-Balke-Collender Co., 110 N.E. 619 (N.Y. 1915) (holding that a response to an offer which matched the offer precisely except for a printed clause requiring the offeror to acknowledge that the response was not an acceptance - no contract formed). Applying the mirror-image rule to transactions in which the parties exchanged printed forms with differing boilerplate clauses (clauses which invariably remain unread by the recipient) yields results with no connection to the parties' expectations or to commercial reality. See Murray, supra note 12, at 38-39. Even under the mirror-image rule, however, courts retained some flexibility. For instance, a response which merely "suggested" a different or additional term, but did not make it a condition to the creation of a contract, could operate as an acceptance. E.g., Rucker v. Sanders, 109 S.E. 857 (N.C. 1921).

14. Such materially altering terms will become part of the contract, however, if the original offeror specifically assents to them.

15. E.g., C. Itoh & Co. v. Jordan Int'l Co., 552 F.2d 1228 (1977).

16. U.C.C. § 2-207(3).

17. Murray, supra note 12, at 40-44.

18. Contrast U.C.C. § 2-207, under which the existence of a material variant term is a response to an offer does not by itself prevent contract formation, although materiality will prevent an additional term from automatically becoming part of a contract between merchants under subsection (2)(b). But see Roto-Lith, Ltd. v. F.P. Bartlett & Co., 297 F.2d 497 (1st Cir. 1962) (holding that a response which contained material alterations to the offer was, for that reason, not an acceptance but a counter-offer).

19. Under U.C.C. § 2-207, in contrast, an offeror's objection to immaterial variances in the offeree's response will not prevent the response from "operating as an acceptance" (i.e., forming a contract), although if both parties are merchants the objection will prevent the offeree's term from automatically becoming part of their contract under § 2-207(2)(c). The approach in CISG may allow an offeror to escape or enforce a contract at its option, thus facilitating speculation at the offeree's expense. Murray, supra note 12, at 42-43.

20. See Allan Farnsworth, Formation of Contract, in INTERNATIONAL SALES: THE UNITED NATIONS CONVENTION ON CONTRACTS FOR THE INTERNATIONAL SALE OF GOODS § 3.04, at 3-16 (Nina M. Galston & Hans Smit eds., 1984).

22.See, e.g., Marlene Indus. v. Carnac Textiles, 380 N.E.2d 239 (N.Y. 1978) (addition of an arbitration clause in response to an offer was a material alteration). The result under the U.C.C. might change if the seller's exclusion of arbitration were considered a "different term" not subject to § 2-207(2). See JAMES J. WHITE & ROBERT S. SUMMERS, UNIFORM COMMERCIAL CODE section 1-3 at 31-35 (3d ed. 1988). Contra JOHN E. MURRAY, JR., MURRAY ON CONTRACTS § 50D (3d ed. 1990).

23. The court stated:

[T]he Uniform Commercial Code . . . does not apply to this case, because the State Department undertook to fix something that was not broken by helping to creat the Sale of Goods Conventions which varies from the Uniform Commercial Code in many significant ways. Instead, under this analysis, Article 19(1) of the Sale of Goods Convention would apply. That section, as the Commentary to the Sale of Goods Convention notes, reverses the rule of Uniform Commercial Code § 2-207, and reverts to the common law rule. . . . The August 7 letter, therefore, was a conteroffer. . . .
Filanto, 789 F. Supp. at 1238.

24. Although the buyer argued that this conduct "estops [the seller] from denying its acceptance of the contract," the court noted that "this contention is better viewed as an acceptance by conduct argument." Id. at 1238.

29. After invoking the Restatement and cases applying domestic contract law on acceptance by silence, the court merely added that "[t]he Sale of Goods Convention itself recognizes this rule" (citing Article 18(1)). Filanto, 789 F. Supp. at 1240. The court also cited CISG Article 8(3) in arguing that Filanto's post-contract formation conduct recognizing the applicability of other terms of the Russian Agreement had bound it to the arbitration term. Id. at 1240-41.

30. "[T]he Court will interpret the 'agreement in writing' requirement of the Arbitration Convention in light of, and with reference to, the substantive international law of contract embodied in the Sale of Goods Convention." Id. at 1237.

31. The Filanto court itself noted this point: "Although there is as yet virtually no U.S. case law interpreting the Sale of Goods Convention, it may safely be predicted that this will change." Id. (citation omitted).

32. See CISG arts. 1(1)(a) and 100. CISG went into force with respect to the United States on January 1, 1988.

33. See Journal of Law and Commerce CISG Contracting States and Declarations Table, 12 J.L. & Com. 283 (1993) for an updated list of Contracting States to the Convention.

34. CISG Article 6 permits the parties "to exclude the application of this Convention or, subject to Article 12, derogate from or vary the effect of any of its provisions." Article 12 preserves the right of ratifying countries to require written evidence of a contract.

35. In addition to the changes in battle-of-the-forms analysis highlighted in Filanto, CISG departs from U.S. domestic law with respect to the circumstances in which offers are irrevocable, the effect of an acceptance lost or delayed in transmission, and several other contract formation issues. For a detailed comparison of these aspects of CISG and the U.C.C. see Murray, supra note 12.

46. MURRAY, supra note 22, § 82A, B.

47. From another perspective, the parol evidence rule seems primarily a rule of procedure - i.e., it requires the judge rather than the jury to make the factual determination whether the parties intended to discharge prior or contemporaneous agreements that were not included in a writing. See id. § 82B at 376-77. Clearly nothing in Article 8(3) or the rest of the Convention overrules this procedural aspect of the parole evidence rule.

48. "[T]he entire controversy between these parties is subject to and will be resolved by arbitration. Accordingly, it is appropriate that a final judgment issue here containing a mandatory injunction to arbitrate in accordance with the [New York Arbitration] Convention and what this Court finds to be the agreement of the parties."

75. The choice of the term validity is perhaps unfortunate in light of the CISG art. 4(a) rule that the Sales Convention "is not concerned with...the validity of the contract or of any of its provisions...." The court was appropriately dealing not with an issue of validity, but rather with the issue of formation, which - as to the contract - is governed by Part II of the Sales Convention.

87. Art. 1(1)(a) provides that the Sales Convention applies to contracts for the sale of goods between parties whose place of business are in different Contracting States. Supra note 3.

88. The inclination of arbitrators to look to the Sales Convention for the rules governing a transnational sales transaction is paralleled by the fact that in Contracting States, the Convention prevails over conflicting provisions of domestic law. This results in the United States from Article VI, Clause 2 of the Constitution, which makes treaties the "supreme law of the land". Thus, as federal law, the Convention provisions prevail over conflicting state law, which ordinarily provide the source for contract rules. The same has been determined by case law in at least one other Contracting State. Oshevire v. British Caledonian Airways Ltd. (Court of Appeal, Kaduna Judicial Division, Nov. 15, 1990), reprinted in 1990 Uniform L. Rev. 424.
