Commercial sales: the Common European Sales Law compared to the Vienna Sales Convention

If the Common European Sales Law (CESL) is adopted, commercial parties will have the opportunity to choose between two international legal instruments for the regulation of their international commercial sales contracts. Whereas CESL is available to both consumer and commercial sales contracts, the Vienna Sales Convention on the International Sale of Goods (CISG) is intended for commercial sales contracts only. This could suggest that CISG is more suitable for use in commercial sales contracts, as commercial parties usually have different interests compared to consumers. In this article, it is argued that, as CESL remedies major flaws in CISG, in fact CESL is the better choice (also) for commercial parties, in particular because it introduces coherent rules on defects of consent, clearer and more balanced rules regarding the incorporation of standard terms, and a scheme for the testing of the unfairness of standard terms.
