Customary international law is based on State practice. This book presents the international law practice of Germany, the world's fourth-largest economy and a powerhouse of the European Union. That practice makes an important contribution to the creation and development of customary international law. It is the first and only presentation in English of German practice in the field of international law. The 2019 volume also provides comprehensive coverage of Germany's membership of the United Nations Security Council. The book combines a case study approach, providing analysis and commentary on Germany's practice, with a classic digest of primary materials, including diplomatic correspondence, statements and court decisions. The book is an ideal complement to other compilations of international law practice and is an essential resource for scholars and practitioners of international law. It will also be of interest to scholars of international relations, politics and diplomatic studies.

‘The book has a special merit in that it is the only presentation of German international law practice in a systematic form … For anyone interested in international law in its practical application, the book is a great asset, in several respects: it informs about practice, it evaluates practice, and many of the background stories have entertainment value. Perhaps one or the other government employee will not be so ‘amused’ about what he has to read about himself. But everyone will come out of reading it wiser than they went in. The authors have rendered great service to international law.’

‘The volume offers an excellent overview of what Germany said or did in the field of international law in the year in question. In relation to each case study, there is lively commentary by Talmon himself and/or one or more students. The commentary turns what could otherwise be a dry reference work into a lively and interesting read.’
