'The book edited by Aust and Kleinlein focuses innovatively on bridges and boundaries between international law and foreign relations law. It has a compelling structure, diversity of case studies and concludes with observations by two senior scholars in the field, Bradley and McLachlan. Reading the book made me understand better some of my own studies on the evolution of international law in Russia.' Lauri Mälksoo, Professor of International Law, University of Tartu, Estonia
''Bridge or boundary'? is the editors' lead question. Original chapters on classic and novel aspects of the interface between domestic and international law make an important contribution to the emerging field of comparative foreign relations law. In a climate of backlash against international law and governance a most timely book.' Anne Peters, Director, Max Planck Institute for Comparative Public Law and International Law, Heidelberg
