TheEuropean Yearbook of Constitutional Law(EYCL) is an annual publication devoted to the study of constitutional law. It aims to provide a forum for in-depth analysis and discussion of new developments in the field, both in Europe and beyond.

This fourth volume of the EYCL addresses the underexplored and contentious topic of whether the EU possesses a constitutional identity of its own. To date, the main focus of scholarship and case law concerns the constitutional identities of the Member States of the EU. This is because the EU has to respect such identities according to article 4(2) TEU.

The attention for Member States' constitutional identities stands in stark contrast to the notion of an EU constitutional identity. Such an identity features very little in the literature and debate on constitutional identity and the legal architecture of the EU. Consequently, this edition of the EYCL addresses the gap in legal research by studying constitutional identity with a focus on the EU itself.

The book explores various views on whether the EU possesses such an identity and what any possible identity might entail. In this way, a fuller and more inclusive picture can be formed of constitutional identity as it relates to the multilevel constitutional order inhabited by the EU and its Member States.

This volume will be of special interest to constitutional and legal scholars who are interested in EU and national constitutional law, as well as to political scientists. In addition, the book is relevant for judges, government officials, judges and policy-makers who work with EU (constitutional) law and its relationship with national (constitutional) law.
