This book covers the updated papers presented at a seminar in Leiden, the Netherlands in November 2016, which was organized by the Italian Public Comparative and European Law Association (DPCE) and the Department of Constitutional and Administrative Law of Leiden University in celebration of the 200th anniversary of the Dutch Constitution. The seminar brought together a group of Italian and Dutch scholars to discuss timely constitutional themes, such as fundamental rights, constitutional change, parliamentary democracy and constitutional review using the unique and relatively unknown Dutch constitutional experience as a focal point. The method of dialectic confrontation between Dutch and Italian scholars, founded on comparative law, proved to be a productive one. The meeting of national schools and the exchange of ideas and commentaries between scholars of different countries is a great stimulus for acquiring a better understanding of Dutch and comparative constitutional law.
