This text illustrates the core principles of European Union (EU) law. As such it seeks to set out the law of the EU as found in the EC Treaty and Treaty on European Union, as well as the judgments of the European Courts, legislative enactments of the Council of the EU, administrative decisions of the European Commission, and official publications of national and Union institutions. The book examines the EU within the context of globalization processes. It is now widely accepted that the law governing the relations between the Union and the rest of the world cannot be treated separately from the internal law of the Union, and this volume sets out to show how the two interrelate and affect one another. Thus, when dealing with institutional law, the approach adopted here is to look at the role of the institutions under the treaties and also their role under agreements with non-member states. The same approach is taken to economic law.
