Following the adoption of the Treaty on European Union, the concept of Community or Union citizenship has been the subject of widespread academic and political debate. Part I of the book provides a framework within which to examine the concept of Community or Union citizenship, discusses the importance of Member State nationality for both the free movement of persons in the European Community and Union citizenship and, finally, examines the traditional requirement in Community law of involvement in an economic activity. Part II focuses on the relationship between the principle of equal treatment and Union citizenship, given the fact that many of the rights conferred on Union citizens are simply extended to them on the basis of the principle of equal treatment. Finally, Part III looks beyond equal treatment and questions whether a direct relationship can be said to exist between Union citizens and the Union. It also suggests some of the issues relevant to citizenship which may feature at the forthcoming Intergovernmental Conference in 1996.
