The Commentary on the Treaty on the Functioning of the European Union (four volumes) is a major European project that aims to contribute to the development of ever closer conceptual and dogmatic standpoints with regard to the creation of “Europeanised research on Union law”.

Following on from the Commentary on the Treaty of the European Union, this book presents detailed explanations, article by article, of all the provisions of the TFEU, discussing the application of Union law in the national legal orders and its interpretation by the Court of Justice of the EU.

The authors are academics and practitioners from twenty-eight European states and different legal fields, some from a constitutional law background, others experts in the field of international law and EU law.Reflecting the various approaches to European legal culture, this book promotes a system concept of European Union law toward more unity notwithstanding its rich diversity grounded in national traditions.
