WINNER of Book of the Year Prize by the International Forum on the Future of Constitutionalism.This book represents a unique contribution to comparative legal studies by presenting the results of an empirical research project on the use of foreign precedents in constitutional interpretation in 31 jurisdictions worldwide.It expands and updates the outcomes presented in the previous successful book The Use of Foreign Precedents by Constitutional Judges, edited by Tania Groppi and Marie-Claire Ponthoreau and published in 2013 as Volume 1 of the series Hart Studies in Comparative Public Law.This new research, covering countries from all the continents, with special attention to some of the emerging jurisdictions of the Global South, confirms that the practice of making explicit use of foreign precedents is still limited both quantitatively and qualitatively. Judicial dialogue only exists in common law jurisdictions and, even there, ‘judicial bricolage’ is much more common than ‘judicial comparativism’. Since the previous edition, this practice has gone hand in hand with new developments in constitutional law, such as the democratic erosion and backsliding, the emergence of populist movements, the increasing role of regional human rights courts, which in many cases overshadowed foreign sources, and the end of a global vision of constitutionalism.Applying a quantitative and a qualitative analysis, with the support of tables and data, the book gives a more complete picture of the practice of citing foreign precedents in this new and challenging era, resulting in essential reading for comparative and constitutional legal scholars.

In 2007 the International Association of Constitutional Law established an Interest Group on ''The Use of Foreign Precedents by Constitutional Judges'' to conduct a survey of the use of foreign precedents by Supreme and Constitutional Courts in deciding constitutional cases. Its purpose was to determine - through empirical analysis employing both quantitative and qualitative indicators - the extent to which foreign case law is cited. The survey aimed to test the reliability of studies describing and reporting instances of transjudicial communication between Courts. The research also provides useful insights into the extent to which a progressive constitutional convergence may be taking place between common law and civil law traditions. The present work includes studies by scholars from African, American, Asian, European, Latin American and Oceania countries, representing jurisdictions belonging to both common law and civil law traditions, and countries employing both centralised and decentralised systems of judicial review. The results, published here for the first time, give us the best evidence yet of the existence and limits of a transnational constitutional communication between courts.

It reveals details of the extent of visible (and sometimes implied) comparative activity that each of the courts displays in its jurisprudence ... we now have a clearer picture of how some of the most prominent constitutional courts deal (or desist from dealing) with comparable judgments in other countries.François Venter, International Journal of Constitutional Law, Vol. 12, no 1, January 2014The volume ... represents a refreshing approach to complex questions raised in debates about constitutional borrowing, transjudicial communication, or the migration of constitutional ideas ... The Use of Foreign Precedents by Constitutional Judges will be essential reading for scholars seeking to refresh the debates about using foreign law.Hélène Tyrrell, Public Law, April 2014
