Responsibility Regimes for International Peace Operations, written by Eleonora Branca

Eleonora Branca's book, Responsibility Regimes for International PeaceOperations is a valuable and timely contribution to the field.The field of international responsibility is well explored with academic discussions being traceable as far back as Grotius and judicial declarations by the Permanent Court of International Justice.1However, the field remains unsettled and struggling to respond to the growth of actions of non-state actors in particular.2The question of the responsibility gap at the international level gives rise to complex questions on the nature of legal authority, the status of non-state actors, the shared nature of international action, and the role and capability of judicial fora in determining questions of international wrongs, and, indeed, rights.Branca's book takes an interesting approach to tackling the question of the responsibility gap in relation to the field of peace operations.The book advocates for an overarching framework of responsibility regimes, under which can be considered legal responsibility, accountability, and liability.In creating a framework of regimes, Branca argues that each is distinct and can mutually complement and reinforce each other.This has some alignment with previous discussions of multilevel accountability,3 however, Branca provides an interesting and distinct contribution here.
