Catalysts for Change examines the strengths and weaknesses of one of the United Nations' most important human rights mechanisms—the collection of independent experts known as special procedures—as they negotiate the rocky terrain where rights meet reality. These independent experts serve as the eyes and ears of the UN human rights system. Despite their prolific work as experts and advocates, however, there has been no empirical study of their impact at the national level—until now. This book provides concrete evidence of why the system works and ways it can be improved.
