Abstract In response to the growing incoherence of European contract law, the Commission is planning to adopt a common frame of reference (CFR) in 2009. That CFR will effectively constitute a codification in a substantive sense. As a result, in codified systems such as The Netherlands, there will be a shift from the familiar tension between impressionistic harmonisation and systematic codification to a new tension between the system of the national civil code and the system of the substantive European code. Therefore, once the CFR is adopted by the Commission as a tool for revising the acquis and for drafting new directives, national legislators inspired by the codification ideal will have to reconsider their strategies towards the implementation of directives in the area of private law. Three such strategies are considered here: resistance, segregation and surrender. Each of them has advantages, but also disadvantages. None of them solve the tension between national codification and Europeanisation. It seems unlikely that private law will ever (again) be contained exclusively in one comprehensive code, either on the national or on the European level. The CFR will make a comprehensive national codification increasingly difficult to achieve, whereas a comprehensive European Civil Code that replaces national private law both lacks a legal basis and political support. Therefore, we will have to live with a two- (or multi-) level system of private law. As a result, the Dutch and other national legislators will have to revise their codification ideals.
