We are delighted to bring to the readers what in our view is a truly fascinating book, National Constitutions in European and Global Governance: Democracy, Rights, the Rule of Law – National Reports. The book contains twenty-nine in-depth national reports, which are available online in two volumes via Open Access. The book will be accompanied by a comparative monograph − referred to in this book as the ‘Comparative Study’ − as is explained in greater detail in the introductory chapter; the Comparative Study will be published later this year. The national reports were prepared in the framework of the five-year research project ‘The Role and Future of National Constitutions in European and Global Governance’. The research project was funded through a 1.2 million EUR grant, awarded by the European Research Council (ERC) (Grant Agreement No. 284316; project acronym: ConstEurGlobGov), as part of the EU’s Seventh Framework Programme. The reports are the result of extensive research by more than sixty contributors, whose posts and affiliations are listed at the beginning of each national report. The full, alphabetical list of all contributors is provided in the ‘Contributors’ section. However, here we would like to make special mention of and gratefully acknowledge the central, pivotal contribution of the main constitutional law experts to the preparation and co-ordination of the twenty-nine national reports. The list of the main constitutional law experts for the countries covered in the research project is provided below.
