This book offers an innovative insight into constitutionalism as a well-established framework for describing the legal and political features of the European Union. It revisits and updates the core pillars upon which the European way of life was built – liberal democratic constitutionalism – while confronting the threats the EU is currently facing.

Examining the political tensions that surface in the European Union, the tools used to address the rule of law crisis, and the challenges posed to the autonomy of EU law, while offering a fresh look into contemporary EU policies, the book is a valuable resource for scholars, researchers and practitioners eager to engage in the ongoing European dialogue.
