The book contains 24 contributions from European law scholars and practitioners analysing the constitutional basis of the European Union and the normative orientation of the Common Foreign and Security Policy (CFSP) as well as the central economic and monetary provisions (TFEU) after the Reform Treaty of Lisbon. Presenting the findings of a European research team, which is composed of authors from eight Member States, the publication underlines the aspiration of the editors to thoroughly analyse the constitutional law of the European Union currently in force.
