I. Introduction

Article 48 is the middle of a trinity of articles that are arguably among the most significant provisions in the Convention. The other two provisions are Articles 47 and 49.

Article 48 is in many ways an unremarkable article. The basic premise of the provision is simple - a seller can remedy any of its obligations even after the time of delivery provided he does so without unreasonable delay or inconvenience to the buyer. The philosophy of this article fits neatly within the broader intentions of the CISG to keep contracts "on-foot."

Article 7.1.4 of the UNIDROIT Principles (UNIDROIT) is grounded in the same philosophy. As Bertram Keller notes in his editorial remarks to CSIG Article 37, the civil law tradition has been generally less familiar with the notion of a right to cure,[1] and its inclusion in UNIDROIT does indeed "encourage the world wide acceptance of a general right to cure."[2]

However, there are some critical differences in the approach and effect of CISG Article 48 and UNIDROIT Article 7.1.4. These editorial remarks concentrate principally on the literal and structural differences between CISG Article 48 and UNIDROIT Article 7.1.4.

II. Literal and Structural Differences

As mentioned in the introduction, CISG Article 48 is a simply worded article.[3] There are very few form requirements a seller must comply with before exercising the right provided to seller by this article. Under Article 48(1) a seller can rectify any defect in its performance, provided the contract has not been avoided by the buyer pursuant to Article 49,[4] and it is not unreasonable to do so - that is, there will not be an unreasonable delay in performing the remedy and it will not put the buyer to unreasonable inconvenience or any uncertainty of reimbursement. The seller does not need to provide notice to the buyer of its intention to cure subject to the conditions just mentioned. The seller has a right to cure per se and does not need to activate in any way. However, the seller is left in a position of uncertainty because that right can be overridden if the buyer avoids the contract pursuant to Article 49. Therefore Article 48(2) and Article 48(3) allow the seller to send a request or notice respectively requiring the buyer to indicate whether it intends to terminate the contract. If the buyer indicates that it is prepared to allow the time requested by a seller to cure its breach, then the buyer is precluded from taking advantage of any remedy inconsistent with that allowance - principally the buyer cannot avoid the contract. Similarly, if the buyer fails to respond to the request or notice within a reasonable time, the buyer is deemed to be allowing the seller an opportunity to cure in accordance with the terms of the request or notice. Conceptually, therefore, Articles 48(2) and 48(3) can be likened or viewed as a mechanism to force a Nachfirst notice from a buyer.[5]

Article 7.1.4 UNIDROIT adopts a very different approach. An immediate difference is that it operates for the benefit of any non-performing party, whereas CISG Article 48 is for the benefit of the seller only. This difference has more to do with the overall structure of the UNIDROIT Principles rather than a reflection on the CISG. With this in mind, these editorial remarks will continue to use the language of buyer and seller, as it will enable a more meaningful comparison.

There are two other differences that are significant and deserve comment. The first is that under Article 7.1.4(1)(a) a seller must give the buyer a notice of cure before the right to cure arises. The second difference is that notwithstanding the buyer might have issued a notice of termination, the effects of that purported termination are suspended if the seller issues a valid notice of cure.

In most other respects the counterpart articles are the same. Although expressed differently, the principal effect and purpose of the remaining parts of Article 7.1.4 are that it must be reasonable for the seller to cure.[6]

III. Commentary

As noted above, in the CISG the right to cure exists per se whereas under UNIDROIT it must be invoked by a valid notice to the buyer. In both instruments the purpose of the request or notice as the case be may serves to eliminate any uncertainty. Whilst at one level it might be simply said that the failure of UNIDROIT to recognize the right to cure as a right per se is merely a reflection of the civil law not fully embracing this concept, a notice requirement would serve to avoid another tension that exists in the CISG. Reference was made in the introduction to a trinity of CISG articles. Article 48 is clearly expressed to be subject to Article 49, but what is its relationship to Article 47? There is undoubtedly a potential conflict between these two articles as both refer to reasonableness. The concept of reasonableness is one that appears frequently throughout the CISG. Much has been written on this concept.[7] Anything that is not unreasonable must be reasonable. So whilst it might be reasonable for a seller to offer to cure within eight weeks under Article 48, it may also be reasonable for the buyer to require the cure within six weeks. The buyer's right in Article 47, like Article 48 is a per se right. Although this is perhaps an unlikely tension, it is one that has on occasion been judicially decided.[8] The UNIDROIT position prevents this potential confusion; the first to send an effective notice prevails.

The second difference referred to above was the consequence a notice to cure has on a buyer's attempt to avoid the contract. The "rights of the [buyer] that are inconsistent with the [seller's] performance are suspended until the time for cure has expired" including the effects of any notice of termination. This can only be in interpreted to mean that if the breach is capable of cure it cannot be a "fundamental non-performance";[9] to do otherwise would mean that it was possible to do the impossible and breath new life into a terminated contract.[10] As a result, the UNIDROIT provision has be rightly criticized for the uncertain position in which it places the buyer,[11] and implicit in that criticism is a preference for the CISG Article 48 approach.

The final issue to be noted by way of commentary is the similarity between the articles. Both CISG Article 48 and UNIDROIT Article 7.1.4 require the buyer to receive the relevant communication (request or notice) before the provision becomes effective. While UNIDROIT does generally require receipt,[12] the CISG on the other hand generally prefers to refer to dispatch pursuant to Article 27.[13]

IV. Conclusion

A comparative analysis between CISG Article 48 and UNIDROIT Article 7.1.4 is a useful exercise in the task of understanding each provision better. Often one learns more from understanding what something is not rather than simply trying to interpret what it is. In this instance, besides some common features, it cannot be said that the counterpart provisions in the CISG and the UNIDROIT Principles are 'on all fours' because there contain some important structural differences, which have been identified in these comments and are worthy of further debate.

3. Although not strictly part of the structure of Article 48, it should also be noted that both CISG Article 49(2)(b)(iii) and Article 50 specifically refer to Article 48.

4. On the priority issue between Articles 48 and 49, see X. GmbH v. Y. e.V., Switzerland 5 November 2002 Commercial Court des Kantons Aargau [available at <http://cisgw3.law.pace.edu/cases/021105s1.html>], which suggests that "when the seller notifies the buyer of his readiness for performance, the buyer may not within a reasonable period of time 'resort to any remedy which is inconsistence with performance by the seller.' For this reason, the buyer does not have the right to avoid the contract even in case of an objective fundamental defect as long as and as far as the seller comes up with a remedy (subsequent cure of the defect) and such is still possible" at 4(b)(aa). This case in turn refers to Germany 31 January 1997 Appellate Court [Oberlandesgericht] Koblenz , 2 U 31/96 = CISG Online 256 [available at <http://cisgw3.law.pace.edu/cases/970131g1.html>]. The rationale of these cases is that if the potential exists for the seller to cure then the breach itself cannot be a fundamental one, and therefore the buyer cannot avail itself of Article 49 in any event. Contrast this view with Koch, R. "The Concept of Fundamental Breach of Contract under the United Nations Convention on Contracts for the International Sale of Goods (CISG)" of the Convention on Contracts for the International Sale of Goods (CISG) 1998, Kluwer Law International (1999) 177-354 at p.322.

5. It is particularly interesting to use this conceptualization when debating the priority between CISG Article 47 and CISG Article 48, see the "Commentary" section below. For an explanation of a Nachfrist notice and commentary on CISG Article 47 generally, see the 'Annotated Text of CISG Article 47' and associated links available at <http://www.cisg.law.pace.edu/cisg/text/e-text-47.html>.

6. Although the drafters of the UNIDROIT provisions choose to avoid the use of the word 'reasonable' in the provisions themselves, they do imbue that word into the meaning of Article 7.1.4 through the Official Comments where the word is frequently used. "[T]he comments on the articles are to be seen as an integral part of the Principles" (UNIDROIT).]

7. See in particular Anderson, C.B. "Reasonable Time in Article 39(1) of the CISG - Is Article 39(1) Truly a Uniform Provision" Part I, para. 2.3, at <http://www.cisg.law.pace.edu/cisg/biblio/andersen.html>. Reasonableness is regarded as one of the general principles of the Convention, see Albert H. Kritzer, Overview Comments on Reasonableness, at <http://cisgw3.law.pace.edu/cisg/text/reason.html#over>.

8. See for example Germany 24 September 1998 District Court Regensburg, available online at <http://cisgw3.law.pace.edu/cases/980924g1.html> where it was found that a buyer's purported avoidance following the allowance of a further fourteen day period for delivery was considered to "thwart" the sellers right to cure under Article 48. To simply extract and refer to an issue such as this does run the risk of decontextualizing the decision, however, it would certainly seem that the Court was of the view that the seller's right to cure took precedence to the buyer's right to set an additional period for performance. A better interpretation of the facts in that case may have been that the period allowed by the seller was unreasonable and therefore declaration of avoidance premature.

9. UNIDROIT Article 7.3.1; see general discussion of this point in note 3 above.

10. However, see Janse van Vuuren, E. "Termination Of International Commercial Contracts For Breach Of Contract: The Provisions Of The UNIDROIT Principles Of International Commercial Contracts, 15 Ariz. J. Int'l & Comp. Law 583 at 633, who takes the view that non-performing party may be able to suspend the effects of termination notwithstanding a valid termination by the aggrieved party.

12. See UNIDROIT Article 1.9

13. "Th[e] general rule [of the CISG] making notices effective on dispatch is subject to specific exceptions in Articles 47(2), 48(4), 63(2), 65(1)&(2) and 79(4). Nearly all of these provisions involve a communication by a party who is in breach of contract; the 'receipt' principle was used so that a mishap in transmission would not add to the burdens of the aggrieved party." John O. Honnold, "Uniform Law for International Sales", 3d ed., Kluwer Law International (1999) at p. 217, citing the legislative history of CISG Article 27 at the 1980 Vienna Diplomatic Conference.
