Edited by Yves Haeck, Professor of International Human Rights Law and Director of the Programme for Studies on Human Rights in Context, Faculty of Law and Criminology, Ghent University and Clara Burbano Herrera, Professor of International Human Rights Law, Principal Investigator of the ERC Consolidator Grant IMPACTUM, and Director of the Programme for Studies on Human Rights in Context, Faculty of Law and Criminology, Ghent University, Belgium

‘This book offers an outstanding and timely contribution to the study of the Inter-American Human Rights System. It reveals the broader and often underexplored dimensions of impact that shape law, policy, and human rights practice across the Americas. By addressing a range of topics and drawing on rich examples, the authors capture the dynamic interplay among international institutions, domestic actors, and civil society. A must-read for scholars, practitioners, and anyone seeking to understand the evolving architecture of human rights in the region.’
