Advocating Social Change through International Law, edited by Professors Daniel Bradlow and David Hunter, explores the use of hard and soft international law in advocating for social change. Using case studies rooted in inter alia human rights, international crimes, environmental protection, public heath, and financial regulation, the book focuses on both state and non-state actors’ strategic choices regarding the use of hard and soft international law in advocating for social change. Looking through the social change lens provides new insights into the interplay between soft and hard international law, the perceived costs and benefits associated with hard and soft international law in different contexts, and the factors affecting the effectiveness of hard and soft approaches to international law.
