'An excellent text, especially for its text, cases and materials approach'.Professor Adele Del Guerico, University of NaplesThe first edition of this seminal textbook made a significant impact on the teaching of EU external relations law. This third edition continues to be the leading text in the field. It retains its hallmark dual perspective, looking at questions from the EU constitutional law perspective (the principles, powers, and the role of the Court of Justice of the EU); and the international law perspective (the effect of international law, the position of the EU in international organisations such as the WTO). It continues to explore key policy areas such as trade, security and defence, police and judicial cooperation, the environment, human rights, drawing on the expertise of leading scholars in these fields. The books' 'text, cases and materials' approach, allows students to gain a thorough understanding of how EU law has developed, its judicial interpretation and scholarly appraisal. Lastly, each chapter concludes with a section entitled 'The Big Picture of EU External Relations Law', which weaves together the diverse and complex materials into a coherent whole and stimulates critical discussion of the topics covered. The new edition expands the policy documents and engages more deeply with scholarly discussions in the field. New contributors, including Marisa Cremona, Tamas Molnar and Viktor Szép bring a fresh perspective and expertise to the sector discussion. The text has benefitted from student assistants' participation to advise on writing style and approach, ensuring ease of use and comprehension.
