Book excerpt: This book takes a wide-ranging approach to tackle the complex question of the current state of constitutional democracy in the EU. It brings together a broad set of academics and practitioners with legal and political perspectives to focus on both topical and perennial issues concerning constitutional democracy (including safeguarding the rule of law and respect for fundamental rights) in theory and practice, primarily at EU level but also with due regard to national and global developments. This approach underlines that rather than a single problématique to be analysed and resolved, we are presently facing a kaleidoscopic spectrum of related challenges that influence each other in elusive, multifaceted ways. Critical Reflections on Constitutional Democracy in the European Union offers a rich analysis of the issues as well as concrete policy recommendations, which will appeal to scholars and practitioners, students and interested citizens alike. It provides a meaningful contribution to the array of existing scholarship and debate by proposing original elements of analysis, challenging often-made assumptions, destabilising settled understandings and proposing fundamental reforms. Overall, the collection injects a set of fresh critical perspectives on this fundamental issue that is as contemporary as it is eternal.
