"It is rare to read a book that is entertaining as well as enlightening. Fernando Mendez, Mario Mendez and Vasiliki Triga’s monograph Referendums and the European Union: A Comparative Inquiry is such a book. Thorough, insightful and with details that go far beyond the topic of referendums on European integration, this book is a good introduction to the timely issue of referendums in general. In addition to an historical overview of the institution, the authors provide relevant contextual information and give the reader an insight into the political developments that led to the holding of referendums in the EU countries … the authors are able to make constitutional theory interesting through historical examples that add context to the otherwise rather dreary study of articles and paragraphs."
