The focus of this series is European law broadly understood. It aims to publish original monographs in all fields of European law, from work focusing on the institutions of the EU and the Council of Europe to books examining substantive fields of European law as well as examining the relationship between European law and domestic, regional and international legal orders. The series publishes works adopting a wide variety of methods: comparative, doctrinal, theoretical and inter-disciplinary approaches to European law are equally welcome, as are works looking at the historical and political facets of the development of European law and policy. The main criterion is excellence i.e. the publication of innovative work, which will help to shape the legal, political and scholarly debate on the future of European law.
