Constitutional identity, a new legal Babel in Europe

Abstract

Constitutional identity appears as an increasingly frequent argument in the case law of constitutional courts in Europe. For many authors, it is a way to initiate dialogue with the European Union on equal terms. In this article, we argue that dialogue is not always a source of harmony, because the terms of the interaction are not exactly the same in Luxembourg and in the member states of the European Union. The Court of Justice of the European Union interprets the national identity of the member states in a way that is not always similar to the content given by the States to their constitutional identity. As a consequence, constitutional identity may allow the Member States to strengthen the specificity of their constitutional rules and, in turn, weaken the unity of European constitutionalism. Far from being an Esperanto, constitutional identity rather appears as the new legal Babel in Europe.
