Abstract How does the quest for legitimacy of the European Union relate to the view the European Court of Justice(ECJ) accords to Union citizens, civil society and to private actors? It is submitted that the ECJ is currently developing a jurisprudence under which citizens, as well as their organisations and corporate private actors, are gradually, and in almost complete disregard of the public/private distinction, being included in the matrix of rights and-a crucial point-obligations of the treaties. The ECJ incorporates civil society actors and citizens, beyond notions of representative (citizenship) and participatory (civil society) democracy, into the body of law and thereby reworks its own and the Union's identity. Two core aspects are explored: the first is the reconfiguration of Union citizenship as a norm which triggers the application of the substantive norms of the EC Treaty. The second aspect of this evolution is the creation of private governance schemes, i.e. processes in which, as a rule, private action is regarded as action that has to meet the standards of the Treaty. The analysis shows that the court is disentangling itself from the State-oriented Treaty situation and drawing legitimacy directly from citizens themselves so that judgments should be pronounced In the Name of the Citizens of the European Union. Union Citizenship is destined to be the fundamental status of nationals of the Member States.1
