This collection of papers explores the concept of constitutional identity in theory and with specific reference to Central and Eastern Europe at a time when many countries across but also beyond the region seem to appeal to an identarian rhetoric in order to justify their illiberal political attitudes. Drawing on law, political science, philosophy or sociology, the contributions address salient questions of constitutional and political theory like the understanding of (constitutional) identity in a post-Westphalian legal order, the extent and the stakes of judicial dialogue between national and supranational (European) judges and the so-called abusive legal transplants. As such, the book also touches upon more general topics such as the rule of law, populism, globalization, legal consciousness and legal culture.
