This insightful and timely book explores the complexity and resilience of the discourse on economic constitutionalism over a period of heightened economic and political turbulence since the economic crisis of 2008 and Brexit, and its continuous relevance despite the Covid-19 public health crisis and the Russian invasion of Ukraine. Providing a sustained and comprehensive analysis of the concept of economic constitutionalism in European and global governance, this book evaluates the origins, functions, and normative elements of economic constitutionalism, placing the discussion within contemporary theoretical frameworks. Chapters explore the protection of fundamental rights under the new economic governance of the Eurozone, the constitutionalization of the internal market, and the relationship between international judicial authority, social systems, and geoeconomics. Bringing together scholars with expertise in international and European law, the book examines recent case studies including the EU internal market, WTO law, the CETA, and the ICJ. Offering a variety of legal and theoretical perspectives, this book will be essential reading for students and scholars in constitutional and administrative law, European and international economic law, global governance studies, and trade law. It will also be beneficial for political scientists and sociology theorists looking to gain an understanding of the legal foundations of economic constitutionalism.
