It is indeed a crucial moment now that Central and Eastern European (CEE) countries have begun to join the EU. The Maastricht Treaty was itself, in several respects, a turning point in European construction; Member States then became aware of the increasing influence of EU law and started to defend their autonomy against the ‘attacks’ stemming from it. With the accession of the CEE states, the ‘Solange story: a story about national constitutional courts resisting a straightforward surrender of national legal sovereignties, and insisting on their own role as guardians of any further transfer of powers from the national to the European level’, can now enter into ‘its chapter 3’. National or constitutional identity is the main arm of resistance, and these national reactions require a rethinking of the relationship between national and European law.
