This comprehensive book provides a thorough analytical overview of the European Union's existing law and policy in the field of international trade. Considering the history and context of the law's evolution, it offers an adept examination of its common commercial policy competence through the years, starting with the Treaty of Rome up until the Treaty of Lisbon, as a background for understanding the EU's present role in the World Trade Organization (WTO) framework. Accessible and thought-provoking, chapters offer a legal analysis of EU trade policy after the Treaty of Rome, after the conclusion of the WTO Agreement, at the Treaty of Amsterdam, at the Treaty of Nice, and at the Treaty of Lisbon, taking into account the most recent constitutional developments by the Lisbon Treaty on division of competences between the EU and its Member States.
