GENERAL OVERVIEW OF CONVENTION AND RECOMMENDATIONS

preface

We were two of the Canadian delegates at the diplomatic conference convened by the United Nations and held in Vienna from 10 March to April 11, 1980, to consider the adoption of the draft Convention on Contracts for the International Sale of Goods prepared by the United Nations Commission on International Trade Law (UNCITRAL). The Convention was adopted by the conference in an amended form on April 11, 1980, after three weeks of intensive deliberations.

We have now been asked to prepare a report on the Convention for the use of the Uniform Law Conference of Canada assessing its suitability for adoption by the Provinces and accompanied by a section by section analysis of . . . the Convention.

We are pleased to submit our report herewith. . . . Part I contains our "Overview of the Convention and Recommendations"; Part II contains two analyses of Articles 1-88 of the Convention, one by Prof. Ziegel from a provincial common law perspective and the other by Prof. Samson from a Quebec civil law perspective. . . .

We have had to operate under severe time constraints, and we are all too conscious of the shortcomings in our Report. Nevertheless, we believe it contains enough detail to enable the reader to understand the main features of the Convention and the questions it raises with respect to its adoption by Canada. The two analyses are far from exhaustive and, again, are only intended to indicate to what extent the individual articles of the Convention correspond to the domestic laws of the common law Provinces and the Province of Quebec. In preparing our Report we have made substantial use of earlier work done by us individually for the federal Department of Justice and the Quebec Ministry of Justice.

We wish to express to the officials of both these agencies our grateful appreciation for the many courtesies extended to us both in the preparation of this report and on earlier occasions. We are particularly indebted to Martin Low of the federal Department of Justice for arranging for the translation of our report and looking after the mechanics of its presentation to the Uniform Law Conference.

[Introductory Comments]


1. On 11 April 1980, after five weeks of intensive deliberations in Vienna, a diplomatic conference convened by the United Nations approved the text of a Convention on Contracts for the International Sale of Goods. (1) [1. U.N. Doc. A/Conf. 97/18, 10 April 1980.]

The Convention was drafted by the United Nations Commission on International Trade Law (UNCITRAL) and its adoption marks the culmination of ten years' effort by the UN agency. The purpose of this introduction is to describe the history of the project and to provide an overview of the general structure and salient features of the Convention, coupled with our own reflections on whether Canada, through the Provinces, should subscribe to the Convention and what the effect of such adherence would be on Canadian importers and exporters.

2. History of Uniformity Movement. The history of the quest for a uniform law on the international sale of goods goes back at least to the early thirties when a group of distinguished European scholars began work on such a project under the auspices of the (Rome) International Institute for the Unification of Private Law (Unidroit). The work was interrupted by the war but was resumed in the fifties. At the same time the locus for the new impetus was moved to The Hague and the Dutch government eventually agreed to sponsor a diplomatic conference in an effort to bring the work to a conclusion. Such a conference was held at the Hague in 1964 and it led to the adoption of two conventions, one on a Uniform Law on the Formation of Contracts for the International Sale of Goods (ULFC) and a second on a Uniform Law on the International Sale of Goods (ULIS). (2) [2. The Laws are reproduced in Graveson, Cohn and Graveson, The Uniform Laws on International Sales Act 1967 (Butterworths 1968).]

As their titles indicate, the first convention was solely concerned with the formational aspects of the contract of sale, whereas the second dealt with the substantive aspects of the contract of sale and the rights, duties and remedies of the parties under such a contract.

3. The Hague Conventions did not attract widespread support and, as of 1979, apparently only eight, mainly European, countries had ratified or acceded to the conventions. (3) [3. Viz. Belgium, Federal Republic of Germany, United Kingdom, Gambia, Israel, Italy, Netherlands and San Marino. Israel did not accede to the Formation Convention.]

Canada and the U.S.A. were not among them. The United Kingdom was apparently the only common law jurisdiction to adhere to the Conventions, but its accession was of limited significance in view of the fact that, as a result of a reservation in the terms of accession permitted by the Convention. (4) [4. ULIS Convention, Art. V; ULFC Convention, Annex II, Art. 1.] (the Uniform Laws only applied where the parties themselves had adopted the Uniform Laws as the laws of their contract.)

4. The Uniform Law on Formation was by far the shorter of the two Laws and comprised thirteen articles which, needless to say, did not exhaust the subject. The Uniform Law on Sales was much longer and ran to 101 articles. ULFC was generally received quite favourably, but ULIS attracted much criticism. 5 [5. Cf. Honnold, "The Draft Convention on Contracts for the International Sale of Goods: An Overview" (1979) 27 A.J.C.E. 223, 225 et seq.]

The criticisms fell into two broad categories. The first group of criticisms were of a technical character and revolved around the length of ULIS, its repetitiveness, the complex system of notices, and difficulties surrounding such key concepts as ipso facto avoidance and the definition of fundamental breach. The second group of criticisms were more politically oriented and were founded on the complaint that the Uniform Laws were essentially a Western European creation (which was true) and tended generally to favour the seller's interests (which was less true). In any event the criticisms were sufficiently widespread to chill effectively any movement towards the wider adoption of the Uniform Laws.

5. The UNCITRAL Convention. The United Nations Commission on International Trade Law (UNCITRAL) was established by the General Assembly in 1966 with the object of promoting the progressive harmonization and unification of the law of international trade. (6) [6. See Honnold, "The United Nations Commission on International Trade Law: Mission and Methods" (1979) 27 A.J.C.L. 201.]

The Commission consists of 36 elected members of the United Nations who are drawn from the various geographical regions and principal economic and legal systems of the world. Canada is not a member; but France, West Germany, the United Kingdom and the United States are members. So is Australia. We note these facts in order to indicate that, even though Canada itself is not represented at UNCITRAL, its two legal systems are well represented through other countries.

6. The Commission meets annually but the detailed work on individual projects is frequently delegated to small working groups. During its first decade the Commission focussed its activities on four major areas of international trade law, viz., international sale of goods, international payments, international commercial arbitration, and international shipping legislation. Sales law absorbed an appreciable part of the Commission's time. The Commission scored an early success in this area with the drafting and subsequent adoption in 1974 by a U.N. sponsored diplomatic conference of the Convention on the Limitation Period in the International Sale of Goods. (7) [7. UN Doc. A/Conf. 63/15, June 13, 1974. See further, Symposium, Unification of International Trade Law: UNCITRAL's first Decade (1979) 27 A.J.C.L. 201 et seq.]

7. However, in the sales area, the Commission's main efforts were directed towards a revision of the Uniform Laws with a view to the preparation of revised texts that would prove more acceptable than the 1964 versions to countries of different legal, economic and social systems. A working group was established for this purpose in 1969 and completed its work in 1976. The draft Convention on the International Sale of Goods prepared by the Working Group was approved at a plenary session of the Committee in June 1977. The Working Group subjected the Uniform Law on Formation to a similar review and completed this phase of its work in September 1977. At its eleventh session held in May and June 1978 the Commission approved the draft provisions on Formation and decided at the same time to integrate both draft Conventions into a single Convention to be known as the Convention on Contracts for the International Sale of Goods (CISG). (8) [8. U.N. Gen. Ass., Off. Records: 33rd Sess., Suppl. No. 17, Doc. No. A/33/17, pp. 10 et seq. The acronym CISG is North American in origin and has no official sanction. The draft convention is examined as part of the Symposium, supra n. 7. See also (1979) 106 Journal du droit international 745 et seq., and Problems of Unification of International Sales Law, Working Papers submitted to the Colloquim of the International Ass'n of Legal Science, Potsdam, Aug. 1979 (Oceana, 1980).]

As already noted, the draft Convention was approved at the Vienna Diplomatic Conference. The Conference made a large number of minor changes but very few of substance. . . .

Structure of CISG. CISG follows the same basic structure as the Uniform Laws which it supersedes but it is substantially shorter and, in several respects, simpler than its predecessors. The greater economy of the convention is due to the substitution of two consolidated regimes of buyer's and seller's remedies (9) [9. CISG, arts. 45, 61.] for the multiple provisions in ULIS. CISG has also attempted to meet many of the other criticisms directed at ULIS, notably by greatly simplifying the definition of fundamental breach, (10) [10. CISG, art. 25.] avoiding the complex system of notices, and abolishing the concept of ipso facto avoidance. CISG is divided into three principal parts which deal respectively with the following topics:

PART I-Sphere of Application and General Provisions (Arts. 14-13).

PART II-Formation of the Contract (Arts. 14-24).

PART III-Sale of Goods (i.e. substantive provisions of contract of sale):

Ch. I - General Provisions (Arts. 25-29)

Ch. II - Obligations of Seller (Arts. 30-52)

Ch. III - Obligations of Buyer (Arts. 53-65)

Ch. IV - Passing of Risk (Arts. 66-70)

Ch. V - Provisions Common to the Obligations of the Seller and of the Buyer (Arts. 71-88)

PART IV-Final Provisions (Arts. 89-101). These deal with signature, ratification, acceptance or approval, and accessoion to the Convention. Part IV also contains the important federal-state clause specifically requested by Canada (Art. 93) and the provision (Art. 94) (11) [footnote 11 quotes portions of Arts. 93 and 94.]

8. Annex II to the Convention contains a Protocol amending the Convention on the Limitation Period in the International Sale of Goods. CISG is open for signature and accession by all states and comes into force on the first day of the month following the expiration of 12 months after the date of deposit of the tenth instrument of ratification, acceptance, approval or accession (Art. 99). An acceding state may at the time of ratification etc. declare that it will not be bound by Part II or Part III of the Convention . A state that adopts the Convention and that has also adopted one or both of the Hague Uniform Laws is obliged to denounce them at the time it adopts the Convention .

9. Parts I, II and III of the Convention are clearly and simply written in non-technical language and, for the most part, one does not need to be a comparativist to understand them adequately although no doubt a knowledge of comparative law would be helpful. This does not of course mean that there may not be differences of opinion with respect to the precise interpretation of particular sections. An official commentary would have been very helpful. The UNCITRAL secretariat prepared an unofficial commentary on the draft convention (12) [12. UN Doc. A/Conf./97/5, 14 March 1979, hereafter referred to as the [Secretariat] Commentary.]but, regrettably, no official commentary was approved or authorized to be prepared by the diplomatic conference.

10. Comparison between CISG and Canadian Sales Laws. The legal problems engendered by a contract of sale are basically the same in all mature legal systems but the solutions to them differ widely in detail and not infrequently on questions of principle, even among members of the same legal family. There would appear to be at least five types of sales law, viz. Civilian, Common Law, Scandinavian, Communist, and religiously based systems such as Muhammedan law. Within the civilian family, there are also significant differences, as for example, between German and French law. The differences are no less significant between common law jurisdictions. The United Kingdom substantially codified its sales law in the Sale of Goods Act 1893. The Act has been modestly amended since then but otherwise remains substantially intact. (13) [13. The current law is found in the U.K. Sales of Goods Act 1979, c. 54.]

Closely related areas of law--notably consumer credit law and other areas of consumer concern--have been revised much more extensively. All the Canadian common law provinces have adopted the 1893 Act (14) [14. See, for example, R.S.O. 1970, c. 421, as am. (hereafter also referred to as the OSGA).]but only one (British Columbia) has copied any of the British amendments. On the other hand, the Provinces have enacted a great volume of consumer credit and other consumer related legislation which has no precise counterpart in the U.K. (15) [15. For further details, see Ontario Law Reform Commission, Report on Sale of Goods (1979), vol. 1, pp. 7 et seq. (hereafter referred to as "OLRC Sales Report").]

11. Mais pour le Québec, seule province de droit civil au Canada, les règles de droit applicables à la vente énoncées aux article 1472 ss. du Code civil, sont complétées par les règles générales du droit des obligations, contenues aux articles 982 ss. du Code. A ces dispositions de droit commun, il faut ajouter certaines règles de droit statutaire dictées pour la protection du consommateur.

12. The governing sales law in the U.S. is Article 2 of the Uniform Commercial Code (UCC). All the states, with the exception of Louisiana, and the District of Columbia have adopted the Uniform Commercial Code, which is a joint product of the American Law Institute and the National Conference of Commissioners on Uniform State Laws. Article 2 supersedes the Uniform Sales Act (USA) first adopted by the National Conference in 1906. The Uniform Sales Act differed in significant respects from the British Act of 1893 and Article 2 has widened the gap much more substantially. (16) [16. Ibid., vol. 1, pp. 12-18.]

13. It will be seen therefore that the draftsmen of the UN Convention, like the draftsmen of the Hague Conventions before them, faced a formidable task in trying to reconcile so many conflicting strains. That they succeeded at all is a credit to their perseverance and a reflection of the functional unity that joins the search for solutions in the sales area. The fact remains that CISG is a composite of many influences, though in drafting style it is closer to the civilian model than to the style familiar to common law lawyers. The syncretic nature of CISG raises important questions of interpretation to which we return later. For the moment we list below some of the important differences between the UN Convention and the Sale of Goods Acts obtaining in the common law Provinces and between the Convention and Quebec law:

A. Difference with law of common law provinces

14... Formation

- 1) The binding nature of an irrevocable offer, whether or not it is supported by consideration (Art. 16).

- 2) Adoption of reception rule with respect to the time of acceptance of all offers accepted by communication (Arts. 18(2), 24).

- 3) Abolition of "mirror image" rule with respect to the requirement of exact correspondence between offer and acceptance (Art. 19(2)).

15... Substantive Provisions

- 4) Unless a ratifying state has made a contrary reservation, no writing is required as a condition of the enforceability or formal validity of the contract of sale (Art. 11-12, 96).

- 5) Binding character of modified terms or agreement to terminate contract, even though not supported by consideration (Art. 29).

- 6) No a priori characterization of terms of the contract into warranties and conditions, as is true under the provincial Sale of Goods Acts. Instead the consequences of a breach of either party's obligations are, with few exceptions, determined by the gravity of the breach, that is, by whether or not it amounts to a "fundamental breach" (Arts. 25, 49(1), 64(1).)

- 7) Different rules with respect to the transfer of risk of loss or damage to the goods and with respect to the definition of circumstances amounting to frustration of the contract and the consequence of frustration. (Arts. 66-70, 79).

- 8) Remedies for Breach of the Contract:

- a. The buyer's right to reject non-conforming goods and to cancel a contract for other breaches by the seller are both stronger and weaker under CISG than under the provincial Acts; the same is true with respect to the seller's remedies where the buyer is in breach (Arts. 49(1), 61-64).

- b. The test of remoteness in Art. 74 for the recovery of damages appears to be somewhat more generous in favour of the aggrieved party than the common law rules generally referred to as the rules in Hadley v. Baxendale.

- c. Unlike provincial law, CISG explicitly recognizes the seller's right of resale when the buyer wrongfully refuses to accept and pay for the goods and the buyer's right "to cover" a non-delivery by the seller as the basis for quantifying the measure of damages of the aggrieved party (Art. 75).

- d. Unlike provincial law, CISG also recognizes an aggrieved party's right to demand assurance of performance from the other party as a condition of proceeding with his own performance where he has justifiable grounds for feeling himself insecure (Art. 71).

B. Différences avec le droit Québécois

Dispositions générales

-1) La règle de la recevabilité de tous les moyens de preuve (art. 11). La grande différence qui existe présentement entre l'article 11 de la C.V.I.M. et le Code civil, nous vient de l'article 1235 al. 4, qui constitue une exception au principe général de l'admissibilité de la preuve testimoniale en matiére commerciale.

Formation du contrat

-2) Une proposition ne constitue une offre que si elle est adressée à une ou plusieurs personnes déterminées (art. 14(1)). Une proposition adressée au public en général ne constitue une offre que si l'offrant l'a clairement indiqué (art. 14(2)).

-3) Même si elle est irrévocable, une offre peut être rétractée, si la rétractation parvient au destinataire avant ou en même temps que l'offre (art. 15(2)).

-4) Si aucun délai n'est accordé, l'offre peut être révoquée en tout temps avant la conclusion du contrat (art. 16(1)).

-5) Une offre verbale doit être acceptée immédiatement (art. 18(2) in fine).

-6) La combinaison des articles 23 et 18(2) de la Convention, a pour effet d'admettre la théorie de la réception en matière de formation de contrat. Le droit québécois n'admet cette théorie que lorsque l'offre et l'acceptation sont faites par des moyens de communication différents.

Ventes de marchandises

-7) Le vendeur est responsable de tout défaut de conformité existant au moment du transfert des risques (art. 36(1)).

-8) Délai péremptoire de deux (2) ans accordé à 1'acheteur pour dé-noncer un défaut de conformié (art. 39(2)).

-9) Le droit de l'acheteur de demander des dommages-intérêts moratoires, malgré le délai de grâce consenti au vendeur (art. 47 (2) in fine).

-10) Le droit du créancier à la résolution de plein droit (art. 49).

-11) La vente peut être conclue même si le prix n'est pas déterminé ou déterminable à partir d'élements contenus au contrat (art. 55).

-12) Le vendeur qui a expédié les marchandises peut s'opposer à ce qu'elles soient remises à 1'acheteur, lorsqu'il apparaît que ce dernier n'exécutera pas une partie essentielle de ses obligations (art. 71(2)).

-13) Le vendeur tenu de restituer le prix, doit également les intérêts de ce prix à compter du jour du paiement (art. 84(1)). L'acheteur doit au vendeur l'équivalent de tout avantage ou profit retiré des marchandises, lorsqu'il doit les restituer (art. 84(2)).

-14) En matière de dommages-intérêts, l'article 74 de la C.V.I.. ne précise pas qu'ils ne comprennent que ceux qui résultent directement de l'inexécution du débiteur; de plus cette disposition ne comporte pas de sanction particulière pour le débiteur de mauvaise foi.

-15) Le transfert des risques s'opere au moment où le vendeur exécute son obligation de livraison ou encore, au moment où l'acheteur accomplit son obligation de prendre livraison (art. 66-67-68-69).

16. Several points need to be emphasized with respect to the above lists. First, they are non-exhaustive. Second, no inference is to be drawn from the lists with respect to the superiority or inferiority of a CISG rule simply because it differs from Canadian provincial law. The Ontario Law Reform Commission has recently made recommendations for the adoption of a revised Ontario Sale of Goods Act (17) [17. See supra n. 15.] and a substantial number of its proposed provisions are closer to CISG than the existing Act. In Quebec the Civil Code Revision Office has also recommended the adoption of a revised Civil Code and the proposed rules governing contracts of sale are closer to the CISG provisions than the rules in the existing Civil Code. (18) [18. Office de révision du Code civil, Rapport sur le Code civil du Quebec, vol. 1, Project de Code civil. Editeur Officiel, Quebec.]

In any event, there would be no need for an international Act if the sales rules of the national legal systems were the same.

17. Should Canada Support Adoption of CISG?

In the second part of this report we subject the individual provisions of CISG to more detailed analysis. As will be seen, the convention contains a number of ambiguities and a substantial number of unanswered questions, and in other areas important policy judgments are open to question, at least as seen through the eyes of a Canadian lawyer. Overall, however, as an exercise in international law making and if the technical quality of the convention were the sole desideratum, much can be said in favour of Canada adopting the Convention. In our view, given the crucially important fact that CISG recognizes expressly the parties' rights to vary its terms or to exclude them entirely (see Art. 6), (19) [19. Art. 6: The parties may exclude the application of this Convention or, subject to article 12, derogate from or vary the effect of any of its provisions.] informed businessmen should have little difficulty in being able to live with the Convention. (20) [20. This conclusion is supported by the reply of one of the respondents to the Department of Justice (hereafter DOJ) Questionnaire: "The Draft Convention will not have a substantial effect upon obligations of . . . as a seller or customers of as buyers. The Convention does establish a set of common sense guidelines which should be of value in trade between countries of substantially different legal systems or stages of development."]

It seems to us however that more fundamental questions are at issue than the technical quality of the Convention and that these need to be given careful consideration in determining whether or not Canada should support the Convention in its existing form. These considerations are canvassed in the following paragraphs.

18. Arguments in favour of adoption.

The following points argue in favour of supporting the Convention: (1) The desirability of promoting greater uniformity and progressive harmonization of the private law rules governing commercial transactions in the international arena. (2) The psychological importance of supporting UNCITRAL's work. An immense amount of time and effort has been invested in the CISG project and a rejection of the Convention might be interpreted as a repudiation of the Commission's goals. (3) The need for an "impartial" legal regime to govern contractual trading relationships between developed and under-developed countries and between countries with widely divergent social, economic and legal systems.

19. These points largely speak for themselves but the following elaboration may be helpful. So far as the first point is concerned, an important goal of postwar policy in the international arena has been to liberalize international trade and to reduce or eliminate tariff and non-tariff barriers impeding the flow of goods in international commerce. Divergent national rules in the contractual area may also restrict, or at least complicate, international trade and to the extent that they do conventions such as CISG support the macro-economic efforts in the public law areas.

20. The importance of the second point (support for UNCITRAL's work) is more difficult to evaluate. Obviously UNCITRAL's work should be supported but it cannot be seriously suggested that support for the organization's general objectives must lead to unquestioning acceptance of every convention that is approved by the organization, especially in view of the fact that Canada is not a member of UNCITRAL. The need to weigh costs and benefits still remains.

21. This is also true of the third point, the need for an "impartial" legal regime. If countries x and y do not have a mature sales law, or if parties in those states proposing to engage in trade with each other are not happy to accept the law of either state as the proper law of the contract, then obviously an international sales law may provide an appropriate solution to the parties' difficulties. Their needs and preferences however throw little light on the needs and preferences of contracting parties in other countries who are content to have their contract governed by national law and who would not appreciate the need to opt-out of CISG if they do not wish the Convention to apply to their contract.

22. Arguments against adoption of CISG in its present form.

The reference to the need to opt-out of the Convention if the parties do not wish it to apply is only one of a substantial number of objections that could be raised, although it is no doubt the most important. Other possible objections that should also be considered are the following: (a) The business community in Canada has not pressed for the adoption of an international sales law and it is not clear who would benefit from it; (b) Important aspects of sales law are excluded from the Convention so that the sought after certainty and uniformity may not in fact be reached; (c) Even where the Convention clearly does apply, many questions of exegesis and application will remain uncertain and it will require a substantial period of time to develop a body of reliable and authoritative precedents.

We will deal first with the opting-in and opting-out problem and then return to the other difficulties later. It goes without saying that in listing these possible objections we are not necessarily agreeing with them.

23. The Need to Opt Out of this Convention.

As previously mentioned, the Hague Conventions permitted acceding states to add a reservation not making the Conventions applicable unless the contracting parties had adopted the Uniform Laws (or either of them) as the law of their contract. The UN Convention contains no comparable provision and its terms are binding on contracting parties unless (a) they have excluded the Convention, or part of it, pursuant to Article 6, or (b) a declaration has been made under the "closely related legal rules" clauses in Article 94. (21) [21. For the terms of art. 94 see supra n. 11.]

Neither of these exceptions strikes us as satisfactory as a straight opting-in provision would have been. Canada attempted at the Vienna Conference to have such a change introduced but the resolution received negligible support in committee and it was easily defeated. The question was not even debated at the plenary sessions of the Conference. The authors of this report had previously been told privately that UNCITRAL's Secretariat thought that the opting-in reservation in the Hague Conventions was a mistake and undermined the purpose of an international sales convention. In the view of these officials the effect was to convert the Hague Conventions into a model law and to discourage states from subscribing to them. Presumably the delegates at Vienna were guided by a similar sentiment.

24. One could accept the result with equanimity if one could confidently assume that the Convention will only affect sophisticated businessmen who will know of the need to exclude the Convention if they do not wish it to apply or whose contracts are likely to be drafted with the aid of legal counsel. These assumptions cannot safely be made. Article 1 provides that the Convention applies 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."

Although Article 1 refers to the parties' places of business, there is some doubt whether the Convention is in fact confined to "commercial" contracts or to contracts between merchants. (22) [22. There is some difference of opinion on this question between us. See our individual Comments in Part II of this Report on Article 1 of the Convention.]

The only express exclusions are those listed in Article 2, of which goods bought for "personal, family or household use" are among the more important.

25. Even if one assumes that Article 1 is restricted to contracts between merchants, if Canada and the U.S. were to adopt the Convention (to take one important example) it would still result in a high proportion of the trading contracts between the two countries being governed by the Convention unless the Convention has been excluded in the parties' agreement or the U.S. and Canadian governments have made a declaration under Article 94. Many businessmen, it is safe to assume, would know nothing about the Convention and an intensive educational campaign would be necessary to inform them of the necessity of expressly excluding the Convention if they do not wish it to apply to their contracts. Even this might prove ineffectual since a large volume of business is never reduced to writing or never fully reduced to writing. Businessmen would therefore look to government initiative, via the declaration of non-applicability, to protect them against the unintended application of the Convention.

26. Here too there could be serious difficulties, first, because such declarations apparently must be reciprocal in nature where another Contracting State is involved (23) [23. Art. 94(1). The requirement of reciprocity does not apply where a non-contracting state is involved. While this is a rational distinction (since non-contracting states are not entitled to be consulted about the applicability of the convention), it leads to the curious result that a declaration of exclusion will be easier to make vis-à-vis a non-contracting state than vis-à-vis a contracting state.] and, secondly, because it could be a laborious task to negotiate the necessary agreement with the many governments likely to be involved in the exercise. Still further complications would arise in the Canadian context assuming that sales law falls within the exclusive provincial constitutional competence and that not all the provinces join in requesting the federal government to accede to the Convention on their behalf, or that they make their requests at different times and seek different declarations under Article 94. The federal government might then be involved in a long round of negotiations and businessmen might be hard put to establish with certainty the legal position at any given time.

27. Will CISG serve the needs of the Canadian business community?

We recognize that businessmen often take little interest in legislative developments in the private law area, and that this is equally true of national and international legislation. Nevertheless it seems to us a sound principle of public policy that, in the commercial law area as elsewhere, the legislatures should consider the potential impact of the legislation on the persons likely to be affected by it. So far as we know, UNCITRAL has conducted no formal inquiry into the practical benefits of an international convention in this area (24) [24. Presumably the benefits were regarded as so self-evident that formal empirical studies were regarded as unnecessary. In any event UNCITRAL was merely completing the work begun by Unidroit and the Hague Conferences. The UNCITRAL Secretariat is of course in regular contact with the governments of its member states and with international commercial associations such as the International Chamber of Commerce, and it also had the benefit of government responses when it began its revisionary work on the Uniform Laws.] and, as noted below, we understand the federal government has so far only had a limited opportunity to canvass the views of the Canadian business community. There also appears to be a lack of comprehensive data on current contracting practices in international sales to which Canadian importers or exporters are parties. In the summer of 1979 the Department of Justice distributed a short questionnaire (25) [25. Hereafter referred to as "DOJ Questionnaire".] to companies and/or associations whose members were known to be actively involved in export trade seeking their reactions to the draft UN Convention and also asking some more general questions. Because of time constraints only about a dozen replies were received, six of which came from members of the Canadian Shipbuilding and Ship Repairing Association. Even the replies that were received cannot always be taken at face value because some of the respondents appear to have misunderstood some of the provisions in the draft convention and because some of the replies were ambiguous.

28. Even allowing for these limitations, the answers to the general questions in Part II of the Questionnaire were instructive. Apparently only one of the respondents (26) [26. One of the other replies was ambiguous but its overall sense pointed to a negative answer; we have so treated it.] had encountered a situation where, while negotiating an international sales contract or after the negotiations had been concluded, the parties were unaware of the differences in their systems of law or felt unable to cope with it. (27) [27. Replies to Part II, Q. 1. One large mining corporation wrote as follows: " does about 75% of its business outside Canada. We generally specify the laws of a province or of Canada in our contracts. We have no significant problems dealing with differences in systems of law nor problems in which the parties to one of our contracts were unaware of such differences".]

Only one of the respondents had experienced gaps in an international contract that gave rise to a need for recourse to an international law to fulfill them (sic). The replies to the question, (Q. 2) "... do you feel that the draft convention ... will have a substantial effect upon the obligations of Canadian buyers?" were more mixed. The majority of the 11 respondents said no or that they believed it would not, one said yes, and the rest were unsure or thought it would depend on the nature of the contract. It would seem that the respondents replying 'no' assumed they would be free to exclude the Convention in whole or in part.

29. In response to Question 4, 6 of the 11 respondents thought the draft convention would not be acceptable to their trading partners as compared with three who thought it would; one respondent did not know and another reply was ambiguous. It appears that the negative replies merely indicate that the respondents thought their trading partners would seek contract terms different from those applicable under the Convention and not that they were opposed to the concept of a sales Convention as such.

30. The replies to Question 5 are particularly illuminating. Question 5 read:

(a) Would you prefer to choose the uniform law (the draft convention on contracts for the international sale of goods) only in certain circumstances? (e.g. a situation where the uniform law is chosen in preference to a totally unfamiliar system, where both parties conform to a "neutral legal system")

or

(b) Would you prefer not to be bound by the draft convention unless you specifically "opt in" (stipulate that you do want to be bound by it) in each separate contract, in which you so desired?

or

(c) Would you prefer to be bound automatically by the draft convention, unless you "opt out" (stipulate that you do not want to be bound by it) in each separate contract, in which you so desired?

Only one of the 13 respondents favoured alternative (a); nine clearly or apparently favoured alternative (b), i.e., being allowed to "opt-in" into the convention; two supported the automatic application of the convention (solution (c)); and one was not willing to commit itself without further information. Clearly then the overwhelming number of respondents preferred an opting-in provision over an opting-out provision. This is significant because all the respondents were sophisticated companies who could be expected to appreciate the importance of opting-out if the Convention were to be adopted by Canada.

31. Apart from the information disclosed by the Questionnaire, the following points also appear to be reasonably supportable. First, there is little reported litigation in Canada involving international sales contracts of the type to which CISG would apply. There are even fewer - very few in fact - cases in which conflict of laws issues have been raised by the parties and the court has had to concern itself with foreign law issues. (28) [28. This observation is supported by the paucity of sales cases cited in Castel's Canadian Conflict of Laws (1977), vol. 2, ch. 19. The same phenomenon has been observed in the U.K. See Benjamin's Sale of Goods (1974), ch. 26.]

This suggests either that the parties to international agreements usually manage to resolve any differences out of court or that the disagreements, whatever their character, do not arise out of differences over the proper law of the contract. Thirdly, about two thirds of Canada's trade is with the U.S. It is difficult to see how this trade would be assisted by an international sales convention. Given the CISG provisions, it could have the reverse effect. Much the same could be said about our trading relations with Western Europe, Japan, and other industrialized countries with well established legal systems. If the parties are concerned about the applicable law governing their transaction, they will insert in their contract a choice of law clause. If they fail to do so, it may be either because legal issues do not loom large in their contractual relations, or because the contract contains satisfactory arbitral provisions (as, for example in the international commodities area), or because the parties are relatively indifferent whether it is the seller's law or the buyer's law that will be deemed to apply to their contract.

32. By a process of elimination, therefore, one is led to conclude that a CISG type law is likely to be most useful or needed in a comparatively narrow range of contracts, viz. those involving foreign governments or government trading agencies, or contracts with parties in newly developing countries, where one or other party is unwilling to submit itself to the domestic sales law of the other party and there is no satisfactory alternative. This conclusion needs to be qualified in one respect. It may be argued that even merchants in countries with mature legal systems may prefer to have their contracts governed by the Convention and that they have not done so in the past because it was not there to be adopted. There may well be such merchants (although if there are they have been surprisingly silent), (29) [29. Significantly there do not appear to be any reported English cases in which the parties have adopted the 1964 Conventions as the law of their contract.] but it has no bearing on the question whether they would prefer an opting-in or an opting-out provision. The answers to the Questionnaire clearly indicate that the overwhelming number of respondents preferred not to be governed by the Convention unless they have expressly adopted it as their proper law. It is reasonable to assume that they reflect the general consensus of Canadian importers and exporters.

33. Important gaps in the structure of CISG. Another difficulty about the Convention is that it does not purport to codify the whole law of sales. Important facets of sales law are purposely excluded because agreement could otherwise not have been reached among the UNCITRAL members. Article 4 excludes questions concerning the validity of the contract or of any of its provisions or of any usage, and the effect which the contract may have on the property in the goods sold. "Validity" is not defined but it could embrace a very broad range of questions. In addition, there are other types of questions that are not specifically dealt with in CISG, such as the assignability of rights and the delegability of duties, but that are not expressly excluded from the Convention. For all these reasons a court may often be called upon to consider two or more different bodies of law--first, the lex fori, if that is the proper law of the contract and, if it is not, whatever other law governs the validity of the contract and the questions not covered by CISG; and, secondly, if the contract is upheld, the provisions of the Convention. Further difficulties may arise in giving effect to Article 7(2). This provides that:

Art. 7(2). "Questions concerning matters governed by this Convention which are not expressly settled in it are to be settled in conformity with the general principles on which it is based or, in the absence of such principles, in conformity with the law applicable by virtue of the rules of private international law."

It will be seen therefore that litigation could become even more complex than it is at present where foreign law issues are raised by one of the parties, and the goal of a simple, uniform and readily predictable international law of sales may turn out to be illusory.

34. Absence of precedents in interpreting CISG.

This difficulty is not of course peculiar to an international convention. It arises just as often at the national level where a new and important piece of legislation has been approved by the legislature. However, an international convention of the character of CISG raises special difficulties. Its concepts and language may be unfamiliar to the adjudicator and the process of comprehension and assimilation will be slower than in the case of domestic legislation which is grounded in existing concepts and, even if it is not, will usually be couched in familiar language. The difficulties will be compounded if national courts of states adhering to the Convention apply conflicting interpretations to the same provisions of the Convention.

35. Our own view is that the objection dealt with in the preceding paragraph, though not unimportant, is the least persuasive. The reported decisions under the Hague Sales Conventions, though few in number, do not indicate that the courts experienced undue difficulty in applying their provisions. The same is true of other important conventions in the international trade arena such as the conventions on carriage of goods by sea. Nor is it correct to assume that the courts will be groping in the dark--the UNCITRAL working papers and reports are voluminous and very detailed and should provide considerable guidance on most questions. There is a substantial body of literature both on the Hague Conventions and on the draft UN Convention, and this may be expected to grow rapidly and to be supplemented by full fledged textbooks when the Convention comes into force and has been adopted by a substantial number of important trading nations.

CONCLUSION AND RECOMMENDATIONS

36. As a loyal supporter of the UN and as a major trading nation, Canada has strong reasons to support UNCITRAL's goals and the concept of a uniform international law of sales. But sympathy should be combined with realism and practicality, and support should not be based on a misplaced form of idealism. The question that needs to be asked is whether the gains to Canada and the Provinces, both short term and long term but particularly long term, will exceed the costs of adopting a convention that contains some unfavourable features.

37. Particularly worrisome from Canada's point of view is the need for contracting parties to opt out of the Convention if they do not wish to be bound by its provisions. We have suggested that this requirement would particularly affect small exporters and importers (or those only incidentally involved in the importing and exporting of goods) who are least likely to know of the Convention and who could normally be expected to prefer to be governed by a law more familiar to them. One solution to this difficulty would be for Canada to arrange for joint declarations of exclusion with its close trading partners pursuant to Article 94 of the Convention. However, if our interpretation of the article is correct this would not be a simple matter, first, because not all Canada's important trading partners have the same or closely related sales rules as Canada, and secondly, because not all the Provinces may be agreed on the list of countries with whom a joint declaration should be sought. The need for a common approach by the Provinces seems to us important. Many Canadian businesses have offices and plants in more than one Province and it would greatly complicate their foreign contractual arrangements if they had to maintain separate Article 94 lists for each of the ten Provinces.

38. It may be that we underestimate the ability of smaller Canadian businesses to adjust readily to the UN Convention or that we over-estimate the importance they attach to being governed by a familiar system of law. They may be indifferent about it. We may also over-estimate the logistical and legal difficulties of putting Article 94 to good and effective use. All these points require further exploration, but if the Provinces decide in favour of subscribing to the Convention the importance of an informational campaign to educate the business community about its provisions, and particularly smaller enterprises that are not regularly engaged in the import and export of goods, hardly needs to be emphasized. It seems to us equally desirable that Canada should consult with her close trading partners to ascertain their intentions with respect to the Convention. Certainly Canada has no moral obligation to be among the first states to ratify the convention, particularly not given her complex constitutional position, but our reservations may be dispelled if they are not shared by our trading partners or if experience shows them to be groundless. Our immediate recommendation is therefore in favour of a "wait and see" attitude, coupled with the international consultations referred to above and supported by simultaneous consultations with all branches of Canadian trade and industry (including the important federal and provincial Crown corporations engaged in international trade) to see what additional light they can throw on the issues canvassed in this Report.

39. We should like to conclude on a slightly different note. In our view, Canada was seriously handicapped in making a significant input into the UN Convention because Canada is not a member of UNCITRAL and has not sought to play an active role as an observer at the organization's meetings. We feel this passive role is regrettable in view of Canada's status as one of the world's leading trading nations and we would urge a much more active role as an item to be placed high on the agenda for the 1980s.


A. ANALYSIS OF ARTICLES 1-88 FROM A PROVINCIAL COMMON LAW PERSPECTIVE. *

* For purposes of comparison, the Ontario Sale of Goods Act has been used as the Provincial prototype. The provincial Sale of Goods Acts are almost identical. For a table of concordance of the corresponding section numbers, see G.H.L. Fridman, Sale of Goods in Canada, 2nd ed., pp. 4-5.

PART I

SPHERE OF APPLICATION AND GENERAL PROVISIONS

Chapter I

SPHERE OF APPLICATION


Article 1

(1) 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.

(2) The fact that the parties have their places of business in different States is to be disregarded whenever this fact does not appear either from the contract or from any dealings between, or from information disclosed by, the parties at any time before or at the conclusion of the contract.

(3) Neither the nationality of the parties nor the civil or commercial character of the parties or of the contract is to be taken into consideration in determining the application of this Convention.

COMMENT

1. Article 1 should be read in conjunction with Articles 2 and 3. Article 1 defines the scope of the CISG; Article 2 excludes certain types of sale, while Article 3 clarifies the application of the Convention to contracts of work and materials.

2. The requirement in Art. 1(1)(a) that the parties must have their places of business in different contracting states means that the mere existence of a foreign element is not sufficient. Thus the fact that the parties have different nationalities or that the contract is to be performed, in whole or in part, in a state other than the state in which the contract was concluded will not be sufficient. "Business" and "places of business" is not defined in the Convention. Article 10 however specifies which place of business applies where a party has more than one, and also that if he does not have a place of business reference is to be made to his "habitual residence". Art. 1(1)(b) also adopts the position that the Convention should apply to parties in non-contracting states where the proper law of the contract is the law of a contracting state. The result is a substantial expansion of the scope of CISG, thus promoting the Convention's goal of maximising the uniformity of international sales law. Assume a contract between a Canadian company and an American company, which is to be governed by the law of the State of New York. If the United States has adopted the convention, CISG, rather than the domestic law of New York, will apply to the contract, assuming the U.S. has not invoked the federal-state clause (Art. 93).

3. Article 1 also raises three definitional problems which should be noted:

(a) It is clear from para. (3) that neither the nationality nor the commercial or civil character of the parties affects the applicability of CISG. The same comprehensiveness also applies to the provincial Sale of Goods Acts. The provincial Acts differ however from CISG in that merchant sellers are subjected to a stricter regime of warranty liability than non-merchants. This distinction is not drawn in CISG. For further discussion of this problem see Art. 35. What is less obvious is whether Art. 1, by referring to the parties' places of business, intends to restrict the scope of CISG to persons in business. The secretariat's commentary does not answer the question directly, but, in the light of Art. 2 and 10 the answer would appear to be no, or at least uncertain.

(b) "Contracts of sale" in Art. 1(1) is not defined. It is defined in the OSGA as an agreement for the transfer of general property in goods for a money consideration called the price. The civilian systems appear to adopt a similar, if not identical, definition. Difficulties may arise however with respect to the application of the test, particularly in the near-sales context, to such agreements as equipment leases, hire-purchase and consignment agreements. The Anglo-Canadian courts, where not otherwise required by statute (as under the Personal Property Security Acts), have generally adopted a fairly strict test whereas the American courts have tended to look at the substantive effect of the agreement. The [Secretariat] Commentary offers no guidance as to the type of test to be applied.

(c) A similar difficulty arises with respect to the meaning of goods. The definition in the Ontario Act (s. 1(1)(g)) excludes choses in action but includes growing crops, fixtures and other things attached to land that are to be severed under the contract of sale. Art. 2 suggests that choses in action (incorporeals) are meant to be excluded in their entirety, but it is not clear to what extent this is true of things attached to land that are intended to be severed under the contract of sale. This could be of some significance in contracts for the sale of agricultural products.


Article 2

This Convention does not apply to sales:

(a) of goods bought for personal, family or household use, unless the seller, at any time before or at the conclusion of the contract, neither knew nor ought to have known that the goods were bought for any such use;

(b) by auction;

(c) on execution or otherwise by authority of law;

(d) of stocks, shares, investment securities, negotiable instruments or money;

(e) of ships, vessels, hovercraft or aircraft;

(f) of electricity.

COMMENT

1. The exclusions in Article 2 turn either on the nature of the goods, the character of the parties, or the mode of sale. The exclusions have no exact parallel in the provincial Sale of Goods Acts, although the Acts do distinguish for warranty purposes between sales by merchant and sales by non-merchant sellers.

2. Exclusion (a) is justified in the [Secretariat] Commentary on the ground that consumer sales are frequently regulated by special legislation and that this makes it desirable to continue to apply the appropriate domestic law. All the Provinces have adopted a substantial volume of consumer protection legislation whose provisions are generally non-excludeable. The CISG exclusion is therefore consistent with provincial public policy.

3. Exclusions (b) through (f) rest on different grounds and several of them are perhaps more difficult to justify:

(b) Sales by auction. These are excluded from CISG because they "are often subject to special rules under the applicable national law and it was considered desirable that they remain subject to those rules even though the successful bidder was from a different State" ([Secretariat] Commentary, p. 40). There is no similar exclusion in the provincial Acts.

(c) Sales on execution or otherwise by authority of law. This exclusion again rests on the existence of separate national rules governing execution sales. Another reason is that such sales are unimportant in international trade.

(d) Sales of stocks, shares, investment securities, negotiable instruments or money. "Money" and "things in action" are also excluded from the definition of goods (and therefore from the scope of the Act) in the provincial Acts. It is well settled that "things in action" in the Canadian common law cover all forms of incorporeal property "whether or not the thing in action is evidenced by or incorporated in documents or instruments or other forms of writing, negotiable or otherwise": OLRC Sales Report, p. 54. The sale of stocks, shares, etc. are also governed by separate federal and provincial legislation, thus furnishing another reason for supporting their exclusion from CISG.

(e) Sales of ships, vessels, hovercraft or aircraft. The draft convention did not include hovercraft and this amendment was adopted at Vienna. The exclusion of all four types of goods is based on two grounds: first, because in some legal systems their sale is assimilated to sales of immovables and, secondly, because in most legal systems at least some ships, vessels and aircraft (and presumably also hovercraft) are subject to special registration requirements.

The Canadian delegation did not think these reasons were sufficiently persuasive, and a resolution was introduced to delete the exclusion. The resolution was not successful.

(f) Sales of electricity. The rationales for this exclusion are that in many legal systems electricity is not considered to be goods and because international sales of electricity present unique problems. See [Secretariat] Commentary, p. 40.


Article 3

(1) Contracts for the supply of goods to be manufactured or produced are to be considered sales unless the party who orders the goods undertakes to supply a substantial part of the materials necessary for such manufacture or production.

(2) This Convention does not apply to contracts in which the preponderant part of the obligations of the party who furnishes the goods consists in the supply of labour or other services.

COMMENT

1. Art. 3(1) probably corresponds with the prevailing Canadian law, although one cannot be sure because of the conflict between the two leading British decisions, Lee v. Griffin [(1861) 1 B. & S. 272.] and Robinson v. Graves [[1935] 1 K.B. 579 (C.A.)]. In any event, art. 3(1) appears to embody the sounder and simpler rule [cf. Benjamin's Sale of Goods (Guest ed.), para. 35]. The same rule is supported in the OLRC Sales Report with respect to domestic contracts [p. 46].

2. Art. 3(2) deals with contracts under which the seller undertakes to supply labour or other services in addition to supplying goods, and excludes them from the scope of the convention. The same exclusion applies in Anglo-Canadian law although the courts have applied by analogy sales rules with respect to the supplier's warranty liabilities under such a contract. [see Young & Marten Ltd. v. McManus Childs Ltd. (1969) 1 A.C. 454].


Article 4

This Convention governs only the formation of the contract of sale and the rights and obligations of the seller and the buyer arising from such a contract. In particular, except as otherwise expressly provided in this Convention, it is not concerned with:

(a) the validity of the contract or of any of its provisions or of any usage;

(b) the effect which the contract may have on the property in the goods sold.

COMMENT

1. As have been noted earlier (supra, Part I, para.33), this important article substantially reduces the scope of CISG and in effect brings into play in every international contract as defined in art. 1 two separate bodies of law, viz. (a) this convention, and (b) whichever municipal law or laws govern (i) the validity of the contract, and (ii) the property effects of the contract assuming it is a valid contract.

2. Unidroit has been working on a uniform law on rules governing the validity of international contracts, and these have been circulated by UNCITRAL. [Doc. A/CN.9/143]. However, in view of the difficulty of reaching consensus on a suitable set of rules the UNCITRAL working group preparing the draft convention did not attempt to incorporate such rules into CISG.

3. "Validity" is not defined in art. 4 or elsewhere in CISG. Presumably it includes any defence that may vitiate the contract under the proper law or laws of the contract because, for example, of lack of capacity, misrepresentation, duress, mistake, unconscionability, and contracts contrary to public policy. The exclusion will be of particular importance where the contract contains a disclaimer clause restricting or excluding liability for breach of warranty or other obligation imposed on the seller under the Convention and the buyer invokes the doctrine of "fundamental breach" or impeaches the clause on grounds of unconscionability. [On this see further infra Art. 6]. The exclusion of questions of validity from the reach of CISG is therefore a debilitating if unavoidable weakness.

4. The exclusion from CISG of the property effects of the contract is much less serious. Under the convention, unlike provincial sales law [See e.g., OSGA 12(3), 21, 34, 38, 47], the parties' rights and obligations do not turn on the locus of title. In this respect CISG adopts the same approach as the American Uniform Commercial Code (see UCC 2-401) and is greatly superior to existing provincial law. Property questions will of course remain very important but only for the purpose of determining the rights of buyer and seller vis-a-vis third parties, and vice versa.


Article 5

This Convention does not apply to the liability of the seller for death or personal injury caused by the goods to any person.

COMMENT

1. This article did not appear in the draft convention. It was adopted at Vienna at the suggestion of several delegations who pointed out that the liability of suppliers of defective goods causing personal injuries is governed in many legal systems by separate rules of law and that it has also attracted the attention of separate international conventions. [See Ontario Law Reform Commission, Report on Products Liability (1979), Appendices 3-5.]

2. The Canadian position with respect to the seller's liability is rather different. Under the provincial Sale of Goods Acts a seller is liable for all types of damage caused by defective goods and involving a breach of his warranty objectives, whether the damage is physical or only economic and whether or not he has been negligent. He may also be liable in tort for negligently supplying goods causing physical injury to person or property. The Ontario Law Reform Commission recommended in its Report on Products Liability (1979) imposing a regime of strict liability on all business suppliers of dangerously defective goods, but this recommendation still awaits implementation. It is not clear what effect Art. 5 will have in a common law province that has requested adoption of CISG where a buyer suffers injury because the foreign seller has supplied defective goods. Presumably the buyer will lose his right to sue for breach of warranty under the provincial Sale of Goods Act and will be remitted to a claim in tort under the lex fori. This could leave him in a less favourable position than he is at present if the lex fori only allows recovery in tort where the seller has acted negligently.


Article 6

The parties may exclude the application of this Convention or, subject to article 12, derogate from or vary the effect of any of its provisions.

COMMENT

1. The principle of freedom of contract enshrined in article 6 proceeds from the consensual nature of the contract of sale and also appears in the provincial Acts. [e.g., OSGA 55, cf. UCC 1-102(3)]. CISG differs from modern sales legislation in so far as it imposes no restrictions, other than as provided in art. 2, on the parties' freedom to exclude the provisions of the Convention. (Cf. UCC 2-302, and s. 55 of the U.K. Sale of Goods Act as am. by the Supply of Goods (Implied Terms) Act 1973, and the Unfair Contract Terms Act, 1977).

2. Art. 6 raises an important and difficult question of exegesis. Does it permit the exclusion of obligations imposed under the Convention, however basic, even though such a disclaimer would be treated as unconscionable, and therefore unenforceable, under the applicable municipal law? Would this be a question of validity within art. 4 or would art. 6 take priority? The [Secretariat] Commentary throws no light on these issues.

3. It is not clear what language will be deemed sufficient "to exclude the application of this Convention"? Is a choice of law clause (e.g., "this contract shall be governed by the law of British Columbia") sufficient or must the clause also indicate that the domestic law of the chosen forum is intended to be applied? The [Secretariat] Commentary, p. 44, explains that art. 6 is intended to discourage exclusion of CISG by implication and this suggests that any doubt should be resolved in favour of the applicability of the Convention.


Chapter II

GENERAL PROVISIONS


Article 7

(1) In the interpretation of this Convention, regard is to be had to its international character and to the need to promote uniformity in its application and the observance of good faith in international trade.

(2) Questions concerning matters governed by this Convention which are not expressly settled in it are to be settled in conformity with the general principles on which it is based or, in the absence of such principles, in conformity with the law applicable by virtue of the rules of private international law.

COMMENT

1. There was much discussion in UNCITRAL about the desirability of including in the convention a general requirement of good faith and fair dealing, which would embrace the formation of the contract as well as application and interpretation of the provisions of the convention. Article 7(1) was eventually adopted as a compromise. Although paragraph (1) does not refer specifically to the observance of good faith in the formation of the contract, its language is sufficiently broad to admit of its inclusion. The [Secretariat] Commentary (p. 45) provides numerous examples of situations in which good faith may be a relevant factor and several of them include the formational phase of a contract.

2. Good faith, in the sense of fairness in the exercise of contractual rights and the performance of duties, is not clearly recognized under existing Anglo-Canadian law. Indeed, the contrary is often asserted but there are signs of a movement in the opposite direction. See e.g. Cehave N.V. v. Bremer HG m.b.H. (1976) 1 Q.B. 44 (C.A.). Good faith in the broader sense of fair dealing is a requirement between merchants under Article 2 of the Uniform Commercial Code and is also imposed in many civilian systems. Its adoption is also recommended in the OLRC Sales Report, ch. 7(B). Good faith in bargaining is a more radical concept though here too there are a growing number of common law precedents in Canada that support its adoption.

3. Article 7(2) did not appear in the draft convention and was added at Vienna. It is not however a radical innovation and has a counterpart in art. 17 of ULIS. See Graveson, op. cit., pp. 8-9. An example of a question not directly addressed in the convention is the effect of the buyer's negligence in a claim against the seller for delivering non-conforming goods. Presumably in most cases a tribunal will prefer to deduce the answer from the general provisions of the convention than to rely on a domestic law to which it is referred by the applicable choice of law rule.


Article 8

(1) For the purposes of this Convention statements made by and other conduct of a party are to be interpreted according to his intent where the other party knew or could not have been unaware what that intent was.

(2) If the preceding paragraph is not applicable, statements made by and other conduct of a party are to be interpreted according to the understanding that a reasonable person of the same kind as the other party would have had in the same circumstances.

(3) In determining the intent of a party or the understanding a reasonable person would have had, due consideration is to be given to all relevant circumstances of the case including the negotiations, any practices which the parties have established between themselves, usages and any subsequent conduct of the parties.

COMMENT

1. Art. 8 is concerned with rules for determining the parties' intentions where their language or conduct is ambiguous or, quaere, where, to the knowledge of the other party, the first party was operating under a mistaken assumption of fact.

2. It is difficult to generalize about such a broad and ill-defined area. The objective theory of intention is one that is normally applied in Anglo-Canadian Law, [Waddams, The Law of Contract, pp. 94-95], but the theory cuts both ways and if an offeree actually knows or must have realized that the offeror has a different intention or was labouring under a mistake then he can scarcely argue that it was reasonable for him to rely on an objective interpretation of the other party's conduct. [ Smith v. Hughes (1871) L.R. 6 Q.B. 597]. Prima facie, therefore, art. 8(1) and (2) would appear to be compatible with common law doctrine.

3. It seems clear from the language of art. 8 that it applies to the interpretation of the contract as well as its formational phase. Cf. [Secretariat] Commentary, pp. 46-47. It may be questioned however whether in practice it is always easy to distinguish the intentions of the parties, objectively ascertained, from the intention of one of them. This will be particularly true where they have both signed or approved a writing. Subject to this caveat, Canadian common law appears to support the rule in art.8 (3). Cf. Waddams, op. cit., pp. 20-21. Note however that Anglo-Canadian law is more restrictive in admitting extrinsic evidence to interpret a concluded agreement which is not ambiguous and which is subject to the parol evidence rule.


Article 9

(1) The parties are bound by any usage to which they have agreed and by any practices which they have established between themselves.

(2) The parties are considered, unless otherwise agreed, to have impliedly made applicable to their contract or its formation a usage of which the parties knew or ought to have known and which in international trade is widely known to, and regularly observed by, parties to contracts of the type involved in the particular trade concerned.

COMMENT

1. Article 9 is broadly in accord with Anglo-Canadian law. However, the definition in art. 9(2) of what constitutes a binding usage [frequently, but misleadingly, referred to in English case law as "custom"] goes beyond generally stated Anglo-Canadian law but is agreeable with UCC 1-205(2). The Anglo-Canadian requirement is said to be [Benjamin's Sale of Goods, para. 844; OLRC Sales Report, pp. 174 et seq.] that "the custom (sic) must be reasonable, universally accepted by the particular trade or profession or at the particular place, certain, not unlawful and not inconsistent with the express or implied terms of the contract." The CISG and Code tests strike me as more reasonable and practical, though in practice there may be little to choose between them and the Anglo-Canadian test.

2. The [Secretariat] Commentary (p. 48) notes that Article 9 does not provide any explicit rule for the interpretation of expressions, provisions or forms of contract which are widely used in international trade and for which the parties have given no interpretation. In most such cases the missing interpretation will be supplied by the parties' practices and trade usages. Difficulties are only likely to arise where the expression has no accepted meaning or has more than one meaning and each of the parties had in mind a different meaning. This difficulty is a familiar one in domestic law and cannot be overcome by rules of interpretation.


Article 10

For the purposes of this Convention:

(a) if a party has more than one place of business, the place of business is that which has the closest relationship to the contract and its performance, having regard to the circumstances known to or contemplated by the parties at any time before or at the conclusion of the contract;

(b) if a party does not have a place of business, reference is to be made to his habitual residence.

COMMENT

1. Article 10 is important for the purpose of establishing the applicability of CISG under art. 1. Determination of the relevant place of business to determine the place of delivery is also necessary for the purposes of art. 12, 20(2), 24, 31(c), 42(1)(b), 57(1)(a) and 96.

2. See also the comments under art. 1 with respect to the significance of the reference to the parties' place of residence.


Article 11

A contract of sale need not be concluded in or evidenced by writing and is not subject to any other requirement as to form. It may be proved by any means, including witnesses.

COMMENT

1. The [Secretariat] Commentary justifies the exclusion of a writing requirement in art. 11 on the ground that many international sales contracts are concluded by modern means of communication which do not always involve a written contract. An equally persuasive reason is that writing requirements encourage litigation and unmeritorious defences. Writing requirements for contracts of sale were repealed in the U.K. in 1954 [Law Reform (Enforcement of Contracts) Act, 1954, c.34] and in British Columbia in 1958 [Stat. B.C. 1958, c.18], and no adverse consequences have resulted. Very few cases have been reported during the past decade in those Provinces that have retained the requirement and a statistical survey conducted on behalf of the Ontario Law Reform Commission shows that manufacturers frequently ignore the requirements in practice when accepting orders for goods [OLRC Sales Report, pp.108-110]. The OLRC Sales Report also recommended repeal of s.5 of the Ontario Act.

2. The precise scope of the second sentence of art. 11 is not clear. Presumably it was intended to override any requirement under domestic law governing the proof of contracts not reduced to writing such as the "commencement de preuve" under the Quebec Civil Code. What is less clear is whether the sentence also permits the introduction of evidence to add to, vary, or contradict the terms of a writing contrary to the parol evidence rule of the common law.


Article 12

Any provision of article 11, article 29 or Part II of this Convention that allows a contract of sale or its modification or termination by agreement or any offer, acceptance or other indication of intention to be made in any form other than in writing does not apply where any party has his place of business in a Contracting State which has made a declaration under article 96 of this Convention. The parties may not derogate from or vary the effect of this article.

COMMENT

1. Art. 12 constitutes an important exception to Art. 11 and was included at the request of some states (notably the USSR) who felt that countries that regard writing as an essential prerequsite for the enforcement of a contract, or to prove its modification or termination, should be free to exclude Art. 12 and the other relevant provisions of CISG by means of a declaration made pursuant to Art. 96.

2. Three features should be noted about Arts. 12 and 96:

First, the declaration can only be made by a state whose legislation requires contracts of sale to be concluded in or evidenced by writing--it cannot therefore be made by jurisdictions such as British Columbia or the United Kingdom that have deleted writing requirements from their sales legislation or have never had it. (Qu. the position where the domestic law only requires writing for some types of sale?).

Secondly, Arts. 12 and 96 are not restricted to writing requirements concerning the contract of sale, its modification or termination but extend to any communication under Pt. II of this convention.

Thirdly, the declaration cannot embrace other types of communication, e.g., a declaration of avoidance of the contract pursuant to Arts. 26 and 59. Presumeably, however, it is open to a state to restrict its declaration to some of the matters enumerated in Art. 12.

Finally, it is not clear what the exact effect of a declaration will be. Obviously it will mean that a writing will be required, but how complete a writing and at what time? Will a signature be essential? Will a communication not in writing be a total nullity or only inadmissible in legal proceedings? Since CISG does not appear to answer these questions, one possibility would to say that the domestic requirements of the declaring state apply. However, this would create difficulties where the states of two or more contracting parties have filed declarations and their domestic writing requirements are not the same. Will they all have to be complied with?

4. In light of the above observations, it should be clear that Art. 12 creates as many difficulties as it purports to resolve (I have only mentioned some of them) and that, in Canada's case, the Provinces should be discouraged from asking for a declaration under Art. 12.


Article 13

For the purposes of this Convention "writing" includes telegram and telex.

COMMENT

Art. 13 was added at Vienna to ensure that "writing" was interpreted liberally conformably to modern means of communication. The definition in Art. 13 is not exhaustive and it is not clear whether the definition encompasses any "mechanical, electronic or other form of recording of information" (the definition adopted in s. 1.1(1).27 of the OLRC draft Revised Sale of Goods Act), or whether it requires some form of paper imprinted record. "Writing" is referred to or required inter alia in Arts. 29 and 97(2). Query whether the definition also applies to determine whether writing requirements under Art. 12 and 96 have been met where the domestic law of the declarant state has a narrower definition of writing. The answer presumeably is no since the purpose of Art. 12 is to enable a state to retain its own writing requirements for international contracts.


PART II

FORMATION OF THE CONTRACT


Article 14

(1) A proposal for concluding a contract addressed to one or more specific persons constitutes an offer if it is sufficiently definite and indicates the intention of the offeror to be bound in case of acceptance. A proposal is sufficiently definite if it indicates the goods and expressly or implicitly fixes or makes provision for determining the quantity and the price.

(2) A proposal other than one addressed to one or more specific persons is to be considered merely as an invitation to make offers, unless the contrary is clearly indicated by the person making the proposal.

COMMENT

1. Article 14 is very helpfully analysed in the [Secretariat] Commentary to s. 12 of the draft convention (the original section number). It is only necessary therefore to draw attention to the following differences between Art. 14 and the common law and statutory rules obtaining in the common law Provinces:

(a) There is no common law requirement that the proposal must be addressed to one or more "specific" persons; it can be addressed to the world at large if that is the offeror's intention, as it frequently is in the case of unilateral contracts. Cf. Carlill v. Carbolic Smoke Ball Co. (1892) 2 Q.B. 484 (C.A.).

However, the strictness of art. 14 (1) is substantially qualified by the provision in 14(2) that a proposal not addressed to one or more specific persons may be treated as an offer if such an intention is "clearly indicated". [The [Secretariat] Commentary, p. 55, explains that art. 14(2) was adopted as a "middle position" between those legal systems that recognize public offices and those that do not.]

As a result the difference between the CISG and common law positions is substantially narrowed and is only one of presumption and the burden of proof.

(b) At first sight the second sentence of article 14(1) appears to depart substantially from the common law rule in so far as it requires, as a condition of the definiteness of an offer, that it must "expressly or implicity" fix or make provisions, inter alia, for determining the price. The common law rule, as reproduced in s.9 of the Sale of Goods Act, is that if the contract is silent with respect to the price an agreement to pay a reasonable price will be implied.

The requirement of a fixed price in Art. 14(1) is apparently derived from French law and was the subject of intensive debate at Vienna. The debate was complicated by the fact that Art. 51 of the draft convention contradicted what was then Art. 12(1), because it provided that if the contract does not expressly or impliedly make provision for the price, "the buyer must pay the price generally charged by the seller at the time of the conclusion of the contract."

The Francophone countries and delegates from a substantial number of developing states felt that Art. 12(1) was doctrinally sound and necessary to prevent buyers being confronted by sellers with unreasonable prices after the goods had been delivered, and that Art. 51 should be amended to make it consistent with Art. 12(1). Other delegates felt just as keenly that Art. 12(1) was too rigid and needed the ameliorating touch of Art. 51. A compromise was eventually hammered out. Art. 12(1) was retained without change but Art. 51 (now Art. 55) was amended to read as follows:

"Where a contract has been validly concluded but does not expressly or implicitly fix or make provision for determining the price, the parties are considered, in the absence of any indication to the contrary, to have impliedly made reference to the price generally charged at the time of the conclusion of the contract for such goods sold under comparable circumstances in the trade concerned."


Article 15

(1) An offer becomes effective when it reaches the offeree.

(2) An offer, even if it is irrevocable, may be withdrawn if the withdrawal reaches the offeree before or at the same time as the offer.

COMMENT

1. It is not clear to what extent the common law rules of offer differ from the rule in art. 15(1). The common law rule is that an offer cannot be accepted until the offeree learns of it [Cheshire & Fifoot, The Law of Contract, 7th ed., pp. 45-46] but it is not clear whether he must learn of it in the manner intended by the offeror. Art. 15(1) states that an offer is not "effective" until it reaches the offeree. "Reaches" is defined in art. 24 (formerly art. 22) and is interpreted in the [Secretariat] Commentary (p. 71) to mean that "an offeree who learns of an offer from a third person prior to the moment it reaches him may not accept the offer until it has reached him" If this is correct, a purported acceptance by the offeree will be a nullity and the offeror may withdraw even an irrevocable offer at any time before it reaches the offeree.

2. Art. 15(2) deals with the unusual situation where the withdrawal of an offer reaches the offeree before or at the same time as the offer. The meaning of "at the same time" is not defined and could be of importance if the two communications are only separated by minutes and the offer purports to be irrevocable. Presumably a tribunal will be guided by the underlying rationale of 15(2) and (quaere) by whether or not the two communications might be expected to come to the attention of a responsible officer of the offeree at the same time.


Article 16

(1) Until a contract is concluded an offer may be revoked if the revocation reaches the offeree before he has dispatched an acceptance.

(2) However, an offer cannot be revoked:

(a) if it indicates, whether by stating a fixed time for acceptance or otherwise, that it is irrevocable; or

(b) if it was reasonable for the offeree to rely on the offer as being irrevocable and the offeree has acted in reliance on the offer.

COMMENT

1. Three aspects of Art. 16 call for consideration:

(a) Notice to offeree where offer made to the public. Art. 16(1) seems to require that the revocation must actually reach the offeree even where the offer is made to the public. This seems inconsistent with art. 14(2) which, as has been noted, does recognize the validity of offers made to non-specific persons if this was the intention of the person making the proposal. Presumably the meaning of "reaches" must be relaxed accordingly and, in the case of an offer made to the public, or a part thereof, an offer will be effectively revoked if reasonable steps are taken to bring it to the attention of the offerees. [Gaston, para. 34].

(b) Binding character of offer stated to be irrevocable. The Anglo-Canadian common law is exceptional in not recognizing the binding character of an offer stated to be irrevocable unless it is supported by consideration. The reversal of the rule was recommended before the war by an English Law Reform Committee and has been recommended again in a recent Working Paper by the English Law Commission [Firm offers: Working Paper No. 60 (1975)] if the firm offer is made in the course of a business. UCC 2-205 also recognizes the binding character of a firm offer by a merchant for a maximum period of three months and provided it is made in a signed writing. A similar, though not identical, recommendation appears in the OLRC Sales Report, pp. 91-95.

In view of these precedents, there is nothing startling about art. 16(2)(a) and it can be accepted as reflecting modern thinking in the common law as well as the non-common law legal community.

(c) Reasonable reliance by offeree. Art. 16(2)(b) has no clear counterpart in the Canadian common law though there is evidence that some courts may be moving in the same direction by penalizing an offeror who acts in bad faith. Art. 16(2)(b) is also supported by section 89B(2) of the Tent. Rest. 2d on Contracts (American Law Institute, Tent. Drafts Nos. 1-7, 1973), which reads:

"89B. (2) An offer which the offeror should reasonably expect to induce action or forbearance of a substantial character on the part of the offeree before acceptance and which does induce such action or forbearance is binding as an option contract to the extent necessary to avoid injustice."

Since it is often in the interests of the offeror that the offeree should have a reasonable opportunity to determine whether or not to accept the offer, the implication of a firm offer as provided in Art. 16(2)(b) seems to be a fair interpretation of the offeror's intention. Whether the implication should be drawn in a particular case will of course depend on all the circumstances, including the relevant trade practices and usages.


Article 17

An offer, even if it is irrevocable, is terminated when a rejection reaches the offeror.

COMMENT

The common law rule is the same as art. 17 in the case of revocable offers. The standard Anglo-Canadian textbooks on contracts do not discuss the effect of the rejection of an irrevocable offer before the period of the offer has expired, but the implication appears to be that it makes no difference. [See however, contra, s. 35A of the Rest. Contracts 2d, which deals with the termination of a power of acceptance under an option contract and assimilates a rejection of the offer or a defective acceptance with the rules generally governing the termination of agreements.]

At any rate, that is the position of art. 17 and it appears to me to be a sensible position. The question of what amounts to a rejection is dealt with in art. 19.


Article 18

(1) A statement made by or other conduct of the offeree indicating assent to an offer is an acceptance. Silence or inactivity does not in itself amount to acceptance.

(2) An acceptance of an offer becomes effective at the moment the indication of assent reaches the offeror. An acceptance is not effective if the indication of assent does not reach the offeror within the time he has fixed or, if no time is fixed, within a reasonable time, due account being taken of the circumstances of the transaction, including the rapidity of the means of communication employed by the offeror. An oral offer must be accepted immediately unless the circumstances indicate otherwise.

(3) However, if, by virtue of the offer or as a result of practices which the parties have established between themselves or of usage, the offeree may indicate assent by performing an act, such as one relating to the dispatch of the goods or payment of the price, without notice to the offeror, the acceptance is effective at the moment the act is performed, provided that the act is performed within the period of time laid down in the preceding paragraph.

COMMENT

1. The first sentence of Art. 18 possibly goes further than the common law since it fails to take into account a particular mode or place of acceptance prescribed by the offeror. The common law rule is that the offeror is master of his offer and hence is entitled to require such mode and place of acceptance as he deems fit. However, nowadays the courts are relucant to find that an indicated mode of acceptance was intended to be the exclusive mode. Cf. Waddams, op. cit., pp. 63-64, and UCC 2-206(1).

2. Paragraph (2) adopts the reception theory of acceptance common to many civil law jurisdictions, and not the postal theory of the common law. Both rules are defensible and merchants in common law jurisdictions should have no difficulty in adjusting to the reception rule. In any event it is not uncommon for an offer to stipulate that an acceptance is not effective until it reaches the offeror.

3. There is a dearth of Anglo-Canadian authority with respect to the circumstances in which an offer may be accepted by performance or part performance where the offer itself is silent with respect to the question. Art. 18(3) is not too helpful since it merely refers us back to the offer or the parties' practices or the usages of the trade in which they are engaged. UCC 2-206 and section 29 of the American Second Restatement on the Law of Contracts (Tent. Draft) permit acceptance "in any manner and by any medium reasonable in the circumstance" including, it would seem, performance of the requested act. UCC 2-206(1)(b) further provides that: "an order or other offer to buy goods for prompt or current shipment shall be construed as inviting acceptance either by a prompt promise to ship by the prompt or current shipment of conforming ... goods, ...".

The [Secretariat] Commentary (p. 64) to the draft convention indicates that its authors envisage a similar result under art. 18(3).

4. Art. 18(3) raises two other questions:

(a) If the offeree is entitled to accept by performance must he give notice of his election to the offeror where the offeror is not otherwise likely to learn promptly of the election? UCC 2-206(1)(b) says yes, and presumably the same conclusion would be reached under the good faith provisions of art. 7.

(b) Can the beginning of a requested performance constitute an acceptance? UCC 2-206(2) clearly acknowledges the possibility provided prompt notice of the acceptance is given to the offeror. To the same effect, see Restatement on Contracts 2d, s. 63. Semble, the Anglo-Canadian cases have so far only considered the problem in the context of unilateral contracts. See e.g., Errington v. Errington (1952) 1 K.B. 290 (C.A.); Sloan v. Union Oil of Canada Co. Ltd. (1955) 4 D.L.R. 664 (B.C.). The CISG [Secretariat] Commentary (p. 64) recognizes that commencement of requested performance may be a sufficient act of acceptance. The conclusion is supported by the language of art. 18(3), which merely requires assent by performing "an act". This is different from requiring full performance.


Article 19

(1) A reply to an offer which purports to be an acceptance but contains additions, limitations or other modifications is a rejection of the offer and constitutes a counter-offer.

(2) However, a reply to an offer which purports to be an acceptance but contains additional or different terms which do not materially alter the terms of the offer constitutes an acceptance, unless the offeror, without undue delay, objects orally to the discrepancy or dispatches a notice to that effect. If he does not so object, the terms of the contract are the terms of the offer with the modifications contained in the acceptance.

(3) Additional or different terms relating, among other things, to the price, payment, quality and quantity of the goods, place and time of delivery, extent of one party's liability to the other or the settlement of disputes are considered to alter the terms of the offer materially.

COMMENT

1. The rule in paragraph (1) corresponds to the common law rule on the effect of an acceptance containing variant terms. See e.g., Hyde v. Wrench (1840) 49 E.R. 132, Waddams, op. cit., p. 73.

2. Paragraph 2 contains a very modest exception to the "mirror image" rule prescribed in paragraph 1, and does not come to grips with the thornier aspects of the "battle of the forms" so much discussed in American literature. See OLRC Sales Report, pp. 81-86. In particular art. 19 does not indicate whether there is a binding contract where the parties have proceeded to perform although their writings are in conflict and, if there is, whose terms will prevail. UCC 2-207 has attempted to provide some guidance but its provisions have engendered much litigation and dissension. Other jurisdictions have been no more successful in finding satisfactory answers to this intractable problem. Given this circumstance, CISG was probably wise not to rush in where angels fear to tread but to leave it to the courts to work out the answers on a case by case basis.


Article 20

(1) A period of time for acceptance fixed by the offeror in a telegram or a letter begins to run from the moment the telegram is handed in for dispatch or from the date shown on the letter or, if no such date is shown, from the date shown on the envelope. A period of time for acceptance fixed by the offeror by telephone, telex or other means of instantaneous communication, begins to run from the moment that the offer reaches the offeree.

(2) Official holidays or non-business days occurring during the period for acceptance are included in calculating the period. However, if a notice of acceptance cannot be delivered at the address of the offeror on the last day of the period because that day falls on an official holiday or a non-business day at the place of business of the offeror, the period is extended until the first business day which follows.

COMMENT

1. Paragraph (1) provides some sensible rules to determine the commencement of the period of time during which an offer can be accepted and appears to be unobjectionable from a common law point of view.

2. Paragraph (2) is a logical corollary to the reception rule for acceptances adopted in art. 18(2). Since the acceptance is not effective until it reaches the offeror some provision is necessary where the last day for acceptance is a non-business day or an official holiday at the offeror's place of business. The practical effect of art. 20(2) appears to be to extend the period for acceptance by at least one day where the notice of acceptance cannot be delivered. It may of course be longer depending on the circumstances.


Article 21

(1) A late acceptance is nevertheless effective as an acceptance if without delay the offeror orally so informs the offeree or dispatches a notice to that effect.

(2) If a letter or other writing containing a late acceptance shows that it has been sent in such circumstances that if its transmission had been normal it would have reached the offeror in due time, the late acceptance is effective as an acceptance unless, without delay, the offeror orally informs the offeree that he considers his offer as having lapsed or dispatches a notice to that effect.

COMMENT

1. Paragraph (1) deals with the effect of a late acceptance and gives the offeror the option of treating it as an effective acceptance if he so notifies the offeree. I am not aware of any Anglo-Canadian authority that has adopted a similar rule, but it is a reasonable rule and can be justified by analogy with the rule that an acceptance containing variant terms is a counter-offer. Note however that under art. 21(1) the late acceptance takes effect from the date of its receipt and not from the time when the offeror communicates with the offeree.

2. The common law has no counterpart to the rule in art. 21(2), and has no need for it, because of its postal theory of acceptance for letters. Art.21(2) mitigates the rigour of the reception rule and protects the offeree's reasonable reliance interests where he has no reason to anticipate that his acceptance will not reach the offeror on time.


Article 22

An acceptance may be withdrawn if the withdrawal reaches the offeror before or at the same time as the acceptance would have become effective.

COMMENT

1. Article 22 is the counterpart to art. 15 on the effect of a simultaneous offer and its withdrawal and complements the rule in art. 18(2) that an acceptance is effective when it reaches the offeror.

2. The meaning of "at the same time" raises the same questions as in art. 15, which see.


Article 23

A contract is concluded at the moment when an acceptance of an offer becomes effective in accordance with the provisions of this Convention.

COMMENT

The common law rule is the same as the rule stated in art. 23. Art. 23 fails to deal with the situation where the precise time of acceptance cannot be readily established, as in the well known case of Brogden v. Metropolitan Ry Co. (1877) 2 A.C. 666 (H.L.) There is no doubt that a binding agreement exists in such a case and the same is presumably true under the Convention.


Article 24

For the purposes of this Part of the Convention, an offer, declaration of acceptance or any other indication of intention "reaches" the addressee when it is made orally to him or delivered by any other means to him personally, to his place of business or mailing address or, if he does not have a place of business or mailing address, to his habitual residence.

COMMENT

1. Art. 24 is a definition section and is a necessary complement to the Convention's adoption of the reception rule to determine the time of effectiveness of acceptances and other communications.

2. Art. 24 applies a uniform rule to the communication of all types of intention governed by Part II of this convention, including acceptances. As previously indicated, this may conflict with the common law rule that an offeror is master of his offer and is free to determine how and when his offeror may be accepted. See Waddams, op. cit., p. 63. Where an offeror has evinced an intention that an offer must be accepted in a given way presumeably, that will be sufficient to override the presumptive effect of art. 24. See art. 6.

3. The reception rule in art. 24 should be contrasted with the dispatch rule adopted in art. 26 for communications required under Part III of the convention. There the communication is effective from the time of its dispatch and the risk of non-arrival or late arrival lies with the recipient.


PART III

SALE OF GOODS

Chapter I

GENERAL PROVISIONS


Article 25

A breach of contract committed by one of the parties is fundamental if it results in such detriment to the other party as substantially to deprive him of what he is entitled to expect under the contract, unless the party in breach did not foresee and a reasonable person of the same kind in the same circumstances would not have foreseen such a result.

COMMENT

1. Article 25 is a key article because the remedies of the buyer and seller under CISG turn on the character of the breach involved. Generally speaking, if the breach is fundamental the aggrieved party is entitled to avoid the contract; if it is not, he is remitted to a claim in damages although in appropriate circumstances he may also be entitled to seek an order for specific performance. See art. 49,64.

2. The common law rules are different and more complex. The OSGA adopts an a priori system of classification into warranties and conditions with respect to the implied terms of title, description, merchantability, fitness and sale by sample. The breach of a condition, as thus defined, prima facie entitles the aggrieved buyer to reject the goods and avoid the contract, even though the actual breach is minor in character. (In the interests of conciseness I ignore the important qualifications to this rule in ss. 12 and 34-35). With respect to stipulations as to time, s. 11 provides that, unless a different intention appears from the terms of the contract, stipulations as to time of payment are not of the essence and that whether any other stipulation as to time is of the essence of the contract depends on the terms of the contract. So far as other express terms of the contract of sale are concerned, it was for a long time assumed that they would also have to be classified a priorily into warranties and conditions regardless of the severity of the breach.

However, the contrary was held in Cehave N.V. v. Bremer H.G. (1976) Q.B. 44, and as a result of this and other decisions [in particular, Reardon Smith Line Ltd. v. Yngvar Hansen-Tangen (1976) 1 W.L.R. 989 (H.L.)] many observers now detect a trend to bring the law of sales into closer alignment with the general rules governing the consequences of a breach of contract as laid down in the Hong Kong Fir Shipping Co. case [Hong Kong Fir Shipping Co. Ltd. v. Kawasaki Kisen Kaisha Ltd. (1962) 2 Q.B. 26 (C.A.)]. This is that they should be governed by the severity of the breach and not turn on the a priori classification of the term breached.

3. It will be seen therefore that the remedial regime adopted in CISG is not fundamentally opposed to the rules in other branches of Anglo-Canadian contract law and the integrative movement observable in the law of sales. Some lawyers may regret the loss of certainty provided by a system of classification into warranties and conditions, but others will argue that the certainty is bought at too high a price. Mercantile practice itself, with the possible exception of stipulations as to time in the international commodities trade, seems to support the CISG approach. In any event, CISG does not leave the parties adrift in a sea of uncertainty. First, so far as time is concerned, CISG has borrowed the German concept of Nachfrist which enables the aggrieved party to treat a delay in performance as a fundamental breach if the breach is not cured within a reasonable time after notice. [See CISG 47, 63]. Secondly, the parties are always free to make other arrangements with respect to the consequences of a breach and will no doubt frequently do so where stipulations as to time are concerned.

4. I therefore support the CISG approach. However this does not end the inquiry and it needs to be further asked what types of breach should be sufficient to entitle the aggrieved party to avoid the contract and whether it is appropriate to describe such a breach as a fundamental breach. For the purposes of art. 25 a breach is fundamental if it results in such detriment to the other party as substantially to deprive him of what he is entitled to expect under the contract unless he could not reasonably have foreseen such a result. This test is substantially more stringent than the test in the original version of art. 25. This merely required proof of "substantial" detriment to the other party. The change was adopted at Vienna, presumably to accommodate the sentiment that an aggrieved person should only be entitled to avoid a contract for very serious breaches.

5. In my view, the new test is too severe and will make it very difficult in practice for a seller or buyer (but particularly a buyer) to cancel a contract because of defective performance by the other. The other common law delegates at the Vienna Conference were not as disturbed by the change as I was and seemed to feel that verbal formulae do not much matter since they are all subject to interpretation by the courts. I am not as sanguine and still feel that the definition will lead to undesireable results. However, it should be borne in mind that the parties are free to adopt their own definition and in practice it is very common for seller to limit, or even exclude entirely, the buyer's right to reject defective goods and to cancel the contract.


Article 26

A declaration of avoidance of the contract is effective only if made by notice to the other party.

COMMENT

1. "Avoidance" is used in CISG in the sense of cancellation for cause. Cf. UCC 2-106(4), 2-703(f), 2-711(1). "Avoidance" is generally used in Anglo-Canadian law in the context of contracts induced by the misrepresentation or other misconduct of one of the parties rather than to describe the remedy available for breach of a contractual obligation. However, CISG's use of the term seems to me quite acceptable and not likely to cause confusion even among common law lawyers.

2. The OSGA contains no general notice provision corresponding to art. 26. There is an express notice requirement in OSGA 46(2) with respect to the right of resale of an unpaid seller and an implied notice requirement in OSGA 34 involving the buyer's right to reject non-conforming goods. Other situations will be governed by common law principles. The general common law rules are (a) that the party in breach cannot unilaterally terminate the agreement without the consent of the other party [cf. Decro-Wall International S.A. v. Practitioners in Marketing Ltd. (1971) 2 All E.R. 216 (C.A.)]; and (b) that a party who is entitled to elect among two or more remedies must communicate his election to the other party. In other words, the common law, like CISG, does not recognize a doctrine of ipso facto avoidance. There may be circumstances when, at common law, the aggrieved party may have no option but to treat the contract as avoided: for example, where the other party has become bankrupt or, in the case of a sale of specific goods, the goods have been destroyed owing to the seller's fault. In such cases the aggrieved party would not be electing a remedy and a notice requirement would make little sense. It is not clear whether CISG envisages a different result, i.e., whether a declaration of avoidance is always necessary. Cf. arts. 49. 64. Even if the answer is yes, the difference would not appear to be of great practical importance given the fact that no formal requisites are prescribed for the giving of a notice of avoidance. See art. 27.


Article 27

Unless otherwise expressly provided in this Part of the Convention, if any notice, request or other communication is given or made by a party in accordance with this Part and by means appropriate in the circumstances, a delay or error in the transmission of the communication or its failure to arrive does not deprive that party of the right to rely on the communication.

COMMENT

1. The provincial Sale of Goods Acts contain no corresponding provision but the Code has a similar provision in UCC 1-201(26), meaning of "notifies" or "gives" a notice.

2. As previously noted "Art. 27 adopts a dispatch theory for communications under this Part of the Convention as contrasted with the receipt rule adopted under Part II. I think the distinction can be justified. Part II is concerned with communications during the formative phase of a contract where neither party has committed a breach. Art. 27 only applies after a contract has been concluded and where, generally speaking, a breach has occurred. It is not unreasonable therefore that the breaching party should run the risk of a communication not reaching him or not reaching him on time. In any event Part III is not inflexible and contains many exceptions to the general rule in Art. 27. See Arts. 47(2), 48(4), 63(2), 65(1), 65(2), and 70(2)."


Article 28

If, in accordance with the provisions of this Convention, one party is entitled to require performance of any obligation by the other party, a court is not bound to enter a judgement for specific performance unless the court would do so under its own law in respect of similar contracts of sale not governed by this Convention.

COMMENT

1. Art. 28 is based on a similar provision in ULIS 16. The common law and equitable rules for the granting of an order for specific performance (or, its equivalent, judgment for the price in an action by this seller) are contained in ss. 47 and 50 of the OSGA and are much narrower than those recognized, for example, under German or French law [see Dawson, "Specific Performance in France and Germany" (1959) 57 Mich. L. Rev. 495]. The CISG draftsmen, like their predecessors, felt that national courts could not be expected to alter "fundamental principles of their judicial procedure" to accommodate CISG. [[Secretariat] Commentary, p. 77]. This seems reasonable enough. For further discussion of Art. 28, see Comment to art. 46.

2. A small but significant change to art. 28 was made at Vienna. The draft version provided that a court was not bound to make an order for specific performance unless the court "could" do so under its own law. The American delegation felt "could" was too loose since a common law court always possesses the power to make an order for specific performance: what was important, in their view, was whether the order would be made in fact. To accommodate the American concern, "could" was changed to "would".


Article 29

(1) A contract may be modified or terminated by the mere agreement of the parties.

(2) A contract in writing which contains a provision requiring any modification or termination by agreement to be in writing may not be otherwise modified or terminated by agreement. However, a party may be precluded by his conduct from asserting such a provision to the extent that the other party has relied on that conduct.

COMMENT

1. At common law an agreement modifying the terms of an agreement is not binding unless supported by consideration. There are exceptions of varying importance to this rule [e.g., modifications under seal, statutory provisions such as those in the Mercantile Law Amendment Act, R.S.O. 1970, c. 272, s. 16, and, above all, the doctrine of equitable estoppel] - some statutory in origin, others developed by the courts themselves - but the principle itself still applies. The requirement of consideration creates particular difficulties in the so called "duty" cases, i.e., where the seller waives payment of part of the price, or the buyer agrees to pay more than the contractual price [see e.g., Gilbert Steel Ltd. v. University Construction Ltd. (1973) 3 O.R. 286, aff'd 67 D.L.R. (3d) 606 (C.A.)] in consideration of the other party performing his obligations.

2. The common law rule has been widely criticized and it has been abolished in UCC 2-209(1). The OLRC Sales Report also recommends its reversal. Art. 29(1) is not therefore nearly as radical as may appear at first sight and should arouse no concerns.

3. Presumably art. 29(1) is subject to a requirement of good faith on the strength of either art. 7(1) or art. 7(2). Though not expressly required under UCC 2-209(1), the official comment assumes its existence [UCC 2-209, Comment 2] and arguably good faith may be required at common law even in those cases where consideration exists. [cf. "The Atlantic Baron" (1978) 3 All E.R. 1170].

4. The first sentence of art. 29(2) corresponds to UCC 2-209(2), although the Code provision is more circumscribed. A clause requiring modifications to the written contract to be in writing is valid at common law but its effectiveness must be judged in the light of the doctrine of equitable estoppel.

5. The second sentence of art. 29(2) introduces an important, and very necessary, qualification to the rule in the first sentence. A similar qualification is recognized at common law [cf. Hartley v. Hymans (1920) 3 K.B. 475; Chas. Richard Ltd. v. Oppenheim (1950) 1 K.B. 616 (C.A.)] and in UCC 2-209(4). No doubt there may be arguments about the "extent" to which the other party has relied "on that conduct" in a particular case, but this difficulty seems to me unavoidable.


Chapter II

OBLIGATIONS OF THE SELLER


Article 30

The seller must deliver the goods, hand over any documents relating to them and transfer the property in the goods, as required by the contract and this Convention.

COMMENT

Art. 30 corresponds to OSGA 26 and UCC 2-301 and, like its common law counterparts, merely states the obvious. The purpose of art. 30 is to set the stage for the more particularized rules on delivery and the required character of the goods set forth in the succeeding chapters.


SECTION I.

Delivery of the goods and handing over of documents


Article 31

If the seller is not bound to deliver the goods at any other particular place, his obligation to deliver consists: (a) if the contract of sale involves carriage of the goods - in handing the goods over to the first carrier for transmission to the buyer;

(b) if, in cases not within the preceding subparagraph, the contract relates to specific goods, or unidentified goods to be drawn from a specific stock or to be manufactured or produced, and at the time of the conclusion of the contract the parties knew that the goods were at, or were to be manufactured or produced at, a particular place - in placing the goods at the buyer's disposal at that place;

(c) in other cases - in placing the goods at the buyer's disposal at the place where the seller had his place of business at the time of the conclusion of the contract.

COMMENT

1. Art. 31 corresponds to OSGA 28 and UCC 2-308 and contains some very elementary rules about the place of delivery where the contract of sale contains no contrary provisions. Delivery is not defined in art. 31 but presumably has the same meaning as in OSGA 1(1)(d), viz. the voluntary transfer of possession of the goods. In international contracts of a commercial character it is most unlikely that the contract will not spell out the delivery terms more fully; hence art. 31 is not likely to be of great practical importance.

2. (a) Art. 31(a) involves a shipment contract, i.e., a contract obligating the seller to deliver the goods for transmission to the buyer or the buyer's order. In practice, the seller's shipping obligations will be much more precisely specified in terms of a recognized trade term such as "f.o.b.", "c.&.f." or "c.i.f." named place of shipment. CISG, like the OSGA, neither refers to such delivery terms nor attempts to define them. The Code does both: see UCC 2-319 to 2-323, and UCC 2-509.

(b) Art. 31 (b) corresponds to OSGA 28(1) and UCC 2-308(b), but is wider than both in so far as it covers future goods - goods to be manufactured or produced at a particular place - and goods to be drawn from a specific stock as well as specific goods.

(c) Art. 31 (c) embraces the residuary category and corresponds to OSGA 28(1) and UCC 2-308(a). Art. 31(c) only refers to the seller's place of business, but it is clear from art. 9(b) that this includes the seller's habitual residence where the seller has no place of business. Hence there is no difference between CISG and the OSGA and Code provisions on this score.


Article 32

(1) If the seller, in accordance with the contract or this Convention, hands the goods over to a carrier and if the goods are not clearly identified to the contract by markings on the goods, by shipping documents or otherwise, the seller must give the buyer notice of the consignment specifying the goods.

(2) If the seller is bound to arrange for carriage of the goods, he must make such contracts as are necessary for carriage to the place fixed by means of transportation appropriate in the circumstances and according to the usual terms for such transportation.

(3) If the seller is not bound to effect insurance in respect of the carriage of the goods, he must, at the buyer's request, provide him with all available information necessary to enable him to effect such insurance.

COMMENT

1. Art. 32 specifies the seller's obligations under a shipment contract and is unremarkable. Comparable, though not identical provisions, are found in s.31 of the Ontario Act and its provincial counterparts, and in UCC 2-504. The Ontario and Code provisions are discussed in the OLRC Sales Report at pp.338-341.

2. Art. 32 like the other articles with respect to the seller's delivery obligations only applies in the absence of contrary agreement between the parties. In practice, the agreement will spell out the seller's delivery obligations quite precisely by adopting an established shipment term (e.g., F.O.B., C.I.F., C. & F.) and less frequently by incorporating the INCOTERMS of the International Chamber of Commerce or the definitions in UCC 2-319 et seq. As a result the need to rely on art. 32, is not often likely to arise in practice.


Article 33

The seller must deliver the goods:

(a) if a date is fixed by or determinable from the contract, on that date;

(b) if a period of time is fixed by or determinable from the contract, at any time within that period unless circumstances indicate that the buyer is to choose a date; or

(c) in any other case, within a reasonable time after the conclusion of the contract.

COMMENT

1. Art. 33 deals with the time of delivery. Paragraphs (a) and (b) deal with the construction of the agreement where a date or period of time is fixed by or determinable from the contract. Paragraph (c) is concerned with cases where the contract itself prescribes no time.

2. The provincial Sale of Goods Act contain no provisions exactly corresponding to paragraphs (a) and (b), but since they state no more than the obvious this should make no difference. If a statutory text is needed to justify this conclusion, it can be found in OSGA 26 providing that "it is the duty of the seller to deliver the goods ... in accordance with the terms of the contract of sale." Art. 33(c) finds its counterpart in OSGA 28(2).

3. Art. 33 does not deal with the consequences of a delayed or late delivery. This is dealt with in Art. 47 and 49.


Article 34

If the seller is bound to hand over documents relating to the goods, he must hand them over at the time and place and in the form required by the contract. If the seller has handed over documents before that time, he may, up to that time, cure any lack of conformity in the documents, if the exercise of this right does not cause the buyer unreasonable inconvenience or unreasonable expense. However, the buyer retains any right to claim damages as provided for in this Convention.

COMMENT

1. Article 34 is merely an expansion of the seller's basic obligations announced in art. 30, but lacks the detail contained in the preceding articles on the seller's delivery obligations with respect to the goods themselves. Presumably it was thought that the subject is already adequately covered in such well known and widely accepted terms as the International Chamber of Commerce's INCOTERMS and its Uniform Customs and Practice for Documentary Credits (ICC Pub. No. 274 and 290).


SECTION II. Conformity of the goods and third party claims


Article 35

(1) The seller must deliver goods which are of the quantity, quality and description required by the contract and which are contained or packaged in the manner required by the contract.

(2) Except where the parties have agreed otherwise, the goods do not conform with the contract unless they:

(a) are fit for the purposes for which goods of the same description would ordinarily be used;

(b) are fit for any particular purpose expressly or impliedly made known to the seller at the time of the conclusion of the contract, except where the circumstances show that the buyer did not rely, or that it was unreasonable for him to rely, on the seller's skill and judgement;

(c) possess the qualities of goods which the seller has held out to the buyer as a sample or model;

(d) are contained or packaged in the manner usual for such goods or, where there is no such manner, in a manner adequate to preserve and protect the goods.

(3) The seller is not liable under subparagraphs (a) to (d) of the preceding paragraph for any lack of conformity of the goods if at the time of the conclusion of the contract the buyer knew or could not have been unaware of such lack of conformity.

COMMENT

1. From a practical point of view, art. 35 is one of the most important articles in Part III of the Convention. Paragraph (1) of art. 35 states the seller's express obligations with respect to the quantity, quality, and description and packaging of the goods and really only states the obvious. Paragraph (2) addresses itself to the seller's implied obligations with respect to the general and particular fitness of the goods, their packaging, and their required qualities where there is a sale by sample or model. These obligations are only presumptive and are displaced to the extent that the parties "have agreed otherwise". One important example of such displacement is given in paragraph (3), viz. where at the time of the conclusion of the contract the buyer knew or could not have been unaware of such non-conformity.

2. The corresponding provisions are to be found in OSGA ss. 14, 15 16, and 55 and its provincial counterparts. There are close resemblances between the CISG provisions and the provincial provisions but there are also some material differences. There are also some unanswered questions. A detailed comparison would require a lengthy exposition: in
