Abstract: In two very different contexts, the ECJ has effectively held that national private law is to be set aside where it impedes the effectiveness of certain EC law values. This article analyses these instances in order to try and make sense of the concept of the European ?constitutionalization? of private law. It argues, on the one hand, that EC law values should only be imposed upon national private law where they can be translated into subjective rights and, on the other, that the application of EC law provisions on private parties should be limited to cases where these can reasonably be said to carry responsibility for the implementation of those provisions. To enforce EC law in contractual relations beyond these limits not only leads to fragmentation and uncertainty but also, it is submitted, defeats the purpose of enhancing the effectiveness of EC law.
