This series produces high quality scholarship exploring questions of shared responsibility in international law. It provides new perspectives on the responsibility problems that arise from the increasing number of situations in which states, international institutions, and other actors engage in concerted action in the pursuit of common objectives. While such concerted action generally aims to provide beneficial outcomes, all too often it results in harmful ones. If that is the case, the multiplicity of actors involved in the concerted action may complicate the determination and implementation of international responsibility. Books in this series examine the grounds on which international law does and should allow for shared responsibility between all actors involved, and how it can be developed in a way that better enables the determination and implementation of shared responsibility. The series includes both works on positive international law and works of a theoretical and interdisciplinary character. The book series is part of the research project on Shared Responsibility in International Law (SHARES), which has been carried out at the Amsterdam Center for International Law (ACIL) of the University of Amsterdam from 2010 onwards.
