Unity in diversity as Europe's vocation and conflicts law as Europe's constitutional form

"Unity in Diversity" was the fortunate motto of the otherwise unfortunate Draft Constitutional Treaty. The motto did not make it into the Treaty of Lisbon. This essay argues that it deserves to be kept alive albeit in a new constitutional perspective, namely the re-conceptualisation of European law as "new type of conflicts law". The new type of conflicts law which the paper advocates is not concerned with selecting the proper legal system in cases with connections to various jurisdictions. It is instead meant to respond to the increasing interdependence of formerly more autonomous legal orders and to the democracy failure of constitutional states which result from the external effects of their laws and legal decisions on non-nationals. Europe has many means to compensate these shortcomings. It can derive its legitimacy from that compensatory potential without developing federal aspirations. The paper illustrates this approach with the help of two topical examples. The first is the conflict between European economic freedoms and national industrial relations (collective labour) law. The recent jurisprudence of the ECJ in Viking, Laval, and Rüffert in which the Court established the supremacy of the freedoms over national labour law is criticised as a counter-productive deepening of Europe's constitutional asymmetry and its social deficit.
