A.Mandate
UNCITRALās mandate is based on āthe promotion of the progressive harmonisation and unification of the law of international tradeā, and was designed to address concerns that āconflicts and divergences arising from the laws of different States in matters relating to international trade constitute an obstacle to the development of world tradeā.5 Hungary, in 1964, had proposed that the General Assembly consider steps to be taken for progressive development of the law of international trade.
It is worth pausing briefly to consider what the drafters of the mandate intended: what did they mean by āprogressiveā, āharmonisationā, āunificationā and the ālaw of international tradeā?
UNCITRAL does not handle the state-to-state relationships the World Trade Organization does, but addresses cross-border transactions (sales, transport, financing investment), and disputes arising from those transactions. UNCITRAL parties are two commercial entities (eg buyers and sellers, transport companies, e-commerce operators, secured lenders and borrowers, and claimants and insolvent companies), or a commercial entity and a government (eg in public procurement transactions and in investor-state disputes).
UNCITRAL has adopted flexible and functional techniques in fulfilment of its mandate, issuing legislative, contractual and explanatory texts.6 These techniques involve different types of compromise. There are two main types of text: first, āunificationā texts, which are legislative texts involving āthe adoption by States of a common legal standard governing particular aspects of international business transactionsā.7 A common example is an international Convention, such as the United Nations Convention on Contracts for the International Sale of Goods (CISG). Another form of unification is a text that states enact domestically in the form in which it was issued (the only UNCITRAL example is the Uniform Rules on Contract Clauses for an Agreed Sum Due upon Failure of Performance (1983) ā though it should be noted that this text is not treated as one of UNCITRALās major works). As the Chinese representative to the General Assemblyās Legal Committee observed, the effect of a uniform law is to āreplace the municipal laws that would otherwise apply with a universally-accepted regulation of a particular transactionā.8
Secondly, āharmonisationā texts such as Model Laws, legislative guides and non-legislative texts, seek to limit divergence in the rules that apply in different states: as the United Nations Legal Counsel has observed, they are designed to āalleviate the challenges of confronting dense and unfamiliar regimes that otherwise contrive to keep businesses out of international marketsā.9 Harmonisation has been described as āa process whereby the effects of a type of transaction in one legal system are brought as close as possible to the effects of similar transactions under the laws of other countriesā.10 Harmonisation texts are designed to allow states to adopt an UNCITRAL norm in their domestic legal framework, adapted to local circumstances as the state sees fit. Consequently, these norms are texts āthrough which domestic laws may be modified to enhance predictability in cross-border commercial transactions.ā In addition, the incoming commercial legal environment must be certain and predictable ā business-friendly and investor-ready ā as a lack of predictability and quality in the domestic regime could raise barriers to international commerce.11 From this perspective, and as was explained at the 2017 UNCITRAL Congress, the scope of UNCITRALās activities run through establishment of a corporation, financing of the business, international sales (online as well as traditional person-to-person), disputes and ā in some cases ā the winding up of the business.12
Both unification and harmonisation approaches have been described as āpreventiveā, meaning that they avoid conflicts-of-law issues by providing single solutions to replace the different substantive rules that would otherwise apply to a transaction, though the extent of flexibility and so degree of convergence therefore varies. In consequence, all UNCITRAL texts require domestic implementation, such as ratification of a Convention, domestic enactment based on a Model Law or Legislative Guide or use in practice of a non-legislative text.
The notion of āprogressiveā legal reform has its roots in the development of the United Nations Charter. Debates on how to refer to the desired codification of international law raised objections to the use of the word ārevisionā, which was considered to place too much emphasis on change. Consequently, it was decided to refer to the āprogressive developmentā of international law in Article 13(1)(a) of the Charter, to balance stability and change in the law. This approach was followed in the statute of the International Law Commission and in the UNCITRAL mandate.
This āprogressiveā approach is another feature of the UNCITRAL mandate that is not often discussed but provides a crucial explanation as to why the United Nations considered that harmonisation and unification of international trade law were desirable and feasible. The General Assembly noted three characteristics of international trade law that would support convergence (used in this context to refer to unification and/or harmonisation: (1) the notion of party autonomy (subject to any restrictions from domestic law, parties they could contract as they pleased); (2) the concept of pacta sunt servanda (the contract must be faithfully fulfilled), subject to force majeure or similar exceptions; and (3) the recognised use of arbitration rather than domestic dispute settlement, with decisions capable of international enforcement.13 As the General Assembly also heard, the law of international trade was consistent in practice, and it had its roots in the mediaeval lex mercatoria, whose own sources included trade usages and practices, international conventions and model laws, and, in the eyes of some, uniform rules, standard contract forms and clauses, codes of conduct and arbitral awards.14 Indeed, the lex mercatoria had been incorporated into domestic systems (such as the commercial codes in France and Germany), and its principles were applied not as a matter of external imposition, but freely at the national level.15 Combined with developed commercial custom and accepted trade terms (fob, cif, among others), the result was that there was already a high degree of unification in some aspects of international trade ā chiefly, in transport, bankersā commercial credits and in arbitration.16 In addition, the formulating agencies were furthering the use of standardised terms and practices in international trade, and countries had āfound without difficulty that they [spoke] a common languageā.17
Given these features of the law of international trade, it might be queried why the UNCITRAL mandate focused on the progressive unification and harmonisation of the law of international trade rather than on its codification. The answer may be that convergence was considered to be āmore easily achieved in technical branches of the law than in subjects closely connected with national traditions and basic principles of domestic lawā.18 In the General Assembly debate, āinternational trade terms, provisions, customs and practicesā were among the most technical of the items under discussion, and these are the areas specifically referenced in terms of codification in the mandate. (In fact, the private sector has taken the lead in codification of these standards ā an example is the International Chamber of Commerceās Incoterms ā and UNCITRAL has consistently endorsed and promoted the wider acceptance of that work.19)
In other words, it was precisely because further harmonisation or unification of international trade rules and practices would involve āprogressiveā development rather than the external imposition of major revisions, and bilateral commitment would not be required, that the General Assembly saw the potential for what became UNCITRAL.20 The General Assembly concluded that international trade law as regards industrial property, transport (land, sea and air), international sale of goods, supply and erection of plant and machinery abroad, bills of exchange and bankersā commercial credits and commercial arbitration were already subject to a high degree of convergence and thus could be reflected in uniform or harmonisation texts. It identified others in which convergence would be feasible: agency law, cross-border joint ventures, rules governing companies entering into āforeign trade relationsā, and the general law of contract as it applied to international trade.21
It was recognised, however, that progressive development and codification were linked, and should take account of gaps and developments in the existing law. Consequently UNCITRAL, as the International Law Commission, should consider reform in fields āwhich have not yet been regulated by international law or in regard to which the law has not yet been sufficiently developed in the practice of Statesā.22 The General Assemblyās discussion of shortcomings in harmonisation and unification of international trade law, and steps to remedy those shortcomings, expressly included modernisation on a par with harmonisation and unification, especially where developing countries were concerned,23 and modernisation is clearly implicit, though not directly stated, in the mandate. UNCITRALās website accurately describes its work, therefore, as the āthe modernisation and harmonisation of rules on international businessā.24
The above, admittedly detailed, review of the rationale for providing UNCITRAL with a ārule-formulatingā mandate explains clearly that UNCITRAL was not intended to be what would now be called a disruptive body, but one that would unify or harmonise existing practice and supplemen...
