Reviews of the first edition ...Principles of European Constitutional Law constitutes a deep and thorough examination of most of the issues involved in the always complex and controversial European Union's constitutional debate, whose richness is impossible to give account of in this necessarily short review. Gonzalo Arruego Law and Politics Book Review Vol.19, No.10, October 20, 2009 ...presents the quintessence of German European law doctrine in a single volume and should therefore be mandatory reading for anyone who wants to get a holistic perspective of the academic debate on Europe's constitutional foundations...It is impossible to present the richness of thoughts contained in the 833 pages of the book in a short review. Daniel Thym Common Market Law Review Vol 44, May 2007 ...it recommends itself as an enduring scholarly work, which gives an English-speaking audience important, and overdue, access to the long-standing and forever-vigorous traditions of (European) constitutional law that are prevalent within Germany...I have happily passed the summer reading each of the contributions; am a far better (European and constitutional) lawyer for it; and would unhesitatingly recommend the purchase of this book, as well as the very careful perusal of every excellently crafted chapter.

Lenaerts, Professor of European Law, Leuven University. May 2006 The book also provides some useful insights into constitutional understandings. Equally, many of the contributions provide thoughtful analyses and assessments, such as those of Dann on the EU's institutional structure. These will be of particular interest to English readers. And the book provides very detailed expositions of German legal thinking and case law, although the contributors are not afraid to question it. Clive Church Journal of Contemporary European Research Vol 3, Issue 2 This is the second edition of a monumental book, updated since the abandonment of the constitutional treaty and its re-emergence in the form of the Lisbon treaty.
