Businesses would undoubtedly prefer a legal environment with less complexity. In the European Commission’s view, the legal diversity resulting from the 27 different national contract laws of the Member States creates unnecessary legal complexity and constitutes an impediment to the proper functioning of the internal market. While existing European contract law instruments mainly focus on harmonizing aspects of consumer law, with the proposed Common European Sales Law (CESL), the Commission has now firmly extended the scope of European contract law to also cover commercial sales contracts. However, the CESL is not the first instrument to create a set of uniform rules for cross-border commercial sales contracts. At the international level, there is already the United Nations Convention on Contracts for the International Sale of Goods (CISG). The current proposal consequently raises a number of pertinent questions concerning the relationship between the two instruments, as well as the necessity, desirability, choice for legal base and likely success of the European instrument. The introduction of a European instrument for cross-border commercial sales contracts essentially inserts a new, regional instrument between the divergent national laws of the Member States and the international sales convention. Rather than simplifying the legal environment, such a step adds to its complexity. This would only make sense if diversity of national contract laws is a serious problem for business that needs to be tackled by creating uniform (European) rules; the existing uniform rules (CISG) have significant shortcomings, and the new instrument has added value. This article examines the proposed CESL on this basis.
