'Schutze's essay compilation gives a comprehensive overview over the constitutional framework of EU's foreign affairs and the underlying doctrinal problems. It goes beyond a mere illustration and contributes significantly to the academic debate. It is both suitable for a first approach to the European foreign affairs from a legal stand as well for a deeper involvement with this highly relevant subject matter. As a read, it is highly recommendable.' Paulina J. Starski, Yearbook of European Law
