"[This] book not only ranges across constitutional amendment limitation provisions [worldwide], but also provides deep theoretical treatment of a central normative constitutional issue... The book joins deep theory, doctrinal subtlety, and an empirical breadth that exhibits a boundary-pushing interdisciplinarity of a truly outstanding calibre. It is likely to be a key reference point on this crucial issue for a considerable time to come." - Jeff King, David Law, Joana Mendes, and Anne Peters (chair), ICON-S Book Prize 2018 committee
"The book skilfully introduces the phenomenon of unconstitutional constitutional amendments and provides a sophisticated justification for constitutional unamendability... The book's appeal is not only to those studying constitutional change, but also to scholars of comparative law and comparative politics, as well as those brooding over what it means to uphold democracy. It also promises to be an invaluable reference book with its extensive bibliography... Institutional and personal libraries alike had better make room for Unconstitutional Constitutional Amendments." - Tarik Olcay, Constitutional Change
"Roznai's book provides a comprehensive and detailed analysis of unconstitutional constitutional amendments. Roznai discusses the constitutions containing provisions regarding this fascinating phenomenon (be they express or implied), and the courts' reactions to them. The book provides an in-depth analytical review of the problems that eternity clauses present the political authorities and the courts. This is an excellent book that discusses one of the central problems of modern constitutionalism." - Aharon Barak, Professor of Law, Radzyner Law School, The Interdisciplinary Center Herzliya
"This excellent book is not just another addendum to the list of technical problems handled by constitutional experts. In his analysis of the character of the amending power - 'an exceptional authority, yet a limited one' - Yaniv Roznai reaches the very core of constitutionalism. Setting aside the formal positivistic framework, his rich and illuminating reconstruction of the role of 'the people' and the meaning of democracy in a constitutional polity refreshes and deepens the understanding of liberal democracy. In times when liberal democracy is under severe stress almost everywhere and challenged by advocates of illiberal democracy, this book could not be more timely." - Ulrich K. Preuß, Freie Universität Berlin and Hertie School of Governance, Berlin
"The problem of unconstitutional constitutional amendments is one of the most topical issues in comparative constitutional law. Roznai's book offers a rigorous framework for analysis and a global knowledge base. It is a welcome addition to the literature on constitutional amendment and will be an essential reference for unconstitutional amendments for some time to come." - Cheryl Saunders, Laureate Professor Emeritus, Melbourne Law School; President Emeritus, International Association of Constitutional Law
"An unconstitutional constitutional amendment - does it exist? More often than you may have thought. But rarely has it been explored. This book, which truly fills a gap, gives a thorough account of and a theoretical foundation for constitutional unamendabilitya subject that gains more and more importance in modern constitutionalism." - Dieter Grimm, Professor of Law at Humboldt University Berlin, Visiting Professor at Yale Law School, and Justice of the Federal Constitutional Court of Germany (1987-1999)
"The theory of constitutional amendments has, somewhat surprisingly, emerged as one of the most central questions for contemporary constitutional theory. Providing a comprehensive overview of worldwide practice regarding judicial review of constitutional amendments, Yaniv Roznai offers the most sophisticated theoretical account yet of constitutional amendments. This is a work of fundamental importance to everyone concerned with the basics of constitutional theory." - Mark Tushnet, William Nelson Cromwell Professor of Law, Harvard Law School
"[Unconstitutional Constitutional Amendments] provides a persuasive and both normatively and empirically well-informed contribution to the debate on the limits of constitutional amendments. For its clear-cut normative theory alone, this book is seminal reading and will be an essential reference to scholars of constitutional law and constitutional politics for years to come." - Michael Hein, Verfassung und Recht in Übersee
"Unconstitutional Constitutional Amendments is a work of great breadth and theoretical sophistication. It may well be the final word on the coherence of constitutional unamendability and the legitimacy of judicial review of amendments." - Rehan Abeyratne, Indian Law Review
"Roznai's comparative constitutional law account makes the book an essential source, not specifically limited to this subject, but also for studies of constitutional theory and constitutional design." - Ali Acar, European Constitutional Law Review
"It is absolutely terrific in every way, from its truly dazzling scholarship to the intellectual depth on every page." - Sanford Levinson, W. St. John Garwood and W. St. John Garwood, Jr., Centennial Chair in Law, University of Texas at Austin
"Unconstitutional constitutional amendments ... pose a major challenge for public law. Roznai has taken up this challenge and has produced an illuminating analysis of the problem. His book has already been the subject of much praise. Various workshops and conference panels have been devoted to the work and its author. This popularity is well deserved. The book summarizes the previous debate concisely, argues diligently, and makes an innovative contribution to a genuinely difficult problem. Probably the greatest strength of the book is its truly global approach, which sets new standards for comparative constitutional studies. The clarity and rigor of his writing helps Roznai to navigate the reader through dozens of jurisdictions and decades of legal scholarship." - Thomas Wischmeyer, International Journal of Constitutional Law Review
"A veritable encyclopaedia of amendatory power and what various apex courts have done (or not done) with it. And for the cognoscenti, it is a rich theory festival. ... this work is of compelling merit; both painstakingly researched, and elegantly presented in a reader-friendly way ... The work offers an embarrassment de riches and for long will be a source of many comparative constitutional theory studies." - Upendra Baxi, Indian Journal of Constitutional & Administrative Law
"Roznai's book is a terrifically executed account of a constitutional theory justifying the concept of unconstitutional constitutional amendments and the practice of judicial review thereof... The work is a real accomplishment... and deserves reading and consideration by all concerned with constitutional theory. " - Vicki C. Jackson, The Vienna Journal on International Constitutional Law
"The best case yet for limits to the amending power, and Roznai's knowledge of comparative politics is superb. " - John R. Vile, Dean and Professor of Political Science, Middle Tennessee State University
"Any response to this book should acknowledge the depth of its scholarship, the clarity of its analysis and the elegance of its proposed solution. Moreover, the argument successfully unscrambles the apparent conceptual confusion in the idea of an unconstitutional constitutional amendment. " - Adrienne Stone, The Vienna Journal on International Constitutional Law
"The cancerous growth of populism is infecting electoral procedures and may, sooner or later, produce democratically elected majorities capable and willing to adopt constitutional reforms deforming the European acquis constitutionnelle. The debate on unconstitutional constitutional amendments cannot be regarded as devoid of any practical importance. We are fortunate that the doctrinal writings on constitutional amendments are on the rise and that we have publications of such intellectual quality and thoroughness as this book. " - Lech Garlicki and Zofia A. Garlicka, The Vienna Journal on International Constitutional Law
"Yaniv Roznai's book will certainly foster scholarly debate on constitutional identity and constitutional change, as well as the role of constitutional courts in the enforcement of limits to the amending power. Overall, the text is interesting, well-written and enjoyable for the reader … a significant contribution to the scholarly debate on constitutional change." - Sabrina Ragone, The Vienna Journal on International Constitutional Law
"[This is an] extremely fascinating and engaging book ...[that] gives us a wonderful theoretical and practical perspective with which to look at that diversity of the application of constitutional unamendability. Every single analysis of the doctrine is attractive and based on evidence... [it is] a relevant and rich source of theories and practices of constitutional unamendability in a truly comparative context." - Ridwanul Hoque, Indian Journal of Constitutional & Administrative Law
"[This is the] most authentic [text] on the theme of unconstitutional constitutional amendments... [It will] serve the interests of all who are engaged in learning the subject or are engaged in making a constitution or those who are engaged in interpreting and applying the constitution in day to day affairs of a country. Its easy reading, appropriate, and convincing arguments, and examples in support of its theme, are an additional attraction for all those who have any concern for the theory or practice of constitution making or applying." - M.P. Singh, Indian Journal of Constitutional & Administrative Law
"This is an exhaustive book which has achieved the outstanding outcome of sketching out a theoretically challenging and empirically relevant field of constitutional studies. There is still room for more work on the topic, but this is certainly a remarkable beginning." - Marco Goldoni, Public Law
"Yaniv Roznai's Unconstitutional Constitutional Amendments: The Limits of Amendment Powers, is, to my knowledge, the first book to deal with these problems and questions [raised by constitutional unamendability] from both a theoretical and comparative (global) perspective." - Joel I. Colón-Ríos, Constitutional Commentary
