A New Fundamental Freedom beyond Market Integration: Union Citizenship and its Dynamics for Shifting the Economic Paradigm of European Integration

The development of European integration from an economic to a political community has become manifest not just in the continuous addition of non‐economic policy areas to the treaties. The introduction of Union citizenship (and its controversial subsequent development in the European Court of Justice's jurisprudence) has also triggered a paradigm shift in one of the community's core areas, the concept of negative integration hitherto intrinsically linked to the internal market. Thus, neither the individual's quality as a market actor nor his/her involvement in a transnational economic activity is a condition for enjoyment of the market freedoms' core guarantees, these being a right of residence and a far‐reaching claim to national treatment in other Member States, as well as a prohibition on restrictions to the free movement of persons. A new fundamental freedom beyond market integration (‘Grundfreiheit ohne Markt’) has emerged. This process, whose consequences for the welfare systems of the wealthier Member States have been fiercely discussed for some time, however, also threatens to curtail severely the regulatory autonomy at the national level.
