In this book, legal scholars from the EU Member States (with the addition of the UK) analyse the development of the EU Member States' attitudes to economic, fiscal, and monetary integration since the Treaty of Maastricht. The Eurozone crisis corroborated the warnings of economists that weak economic policy coordination and loose fiscal oversight would be insufficient to stabilise the monetary union. The country studies in this book investigate the legal, and in particular the constitutional, pre-conditions for deeper fiscal and monetary integration that influenced the past and might impact on the future positions in the (now) 27 EU Member States. The individual country studies address the following issues: - Main characteristics of the national constitutional system, and constitutional culture; - Constitutional foundations of Economic and Monetary Union (EMU) membership and related instruments; - Constitutional obstacles to EMU integration; - Constitutional rules and/or practice on implementing EMU-related law; and - The resulting relationship between EMU-related law and national law Offering a comprehensive and detailed assessment of the legal and constitutional developments concerning the Economic and Monetary Union since the Treaty of Maastricht, this book provides not only a study of legal EMU-related measures and reforms at the EU level, but most importantly sheds light on their perception in the EU Member States.
