The British Balance of Competences Review, launched in 2012, sparked a lively political and academic debate about the core competences of the European Union. Today, the Balance of Competences Review is no longer just a debate about the EU’s power, but has stimulated much broader issues about the position of the Member States in the European Union. How far does the range of their power reach? is is the central theme of this book. What should the relationship between the Member States and the European Union look like from a liberal perspective? Is the EU a union of liberal states or a liberal union of states? Or both? Readers are invited to sharpen up their own ideas about the position of Member States in relation to European institutions.
