A Critical Introduction to International Criminal Law, authored by Carsten Stahn, explores the rapid evolution of international criminal law following the end of the Cold War. The United Nations’ notion of a new ‘age of accountability’ contrasts with enduring criticisms that question the selectivity and potential victor’s justice in its application. This book delves into these critiques through five key themes: the evolving nature of criminality and international crimes, the balance between individual and collective responsibility, the complexities of domestic, international, hybrid, and regional justice institutions, the underpinnings of judicial procedures, and strategies for punishment and reparation. Ideal for students, academics, and professionals from various disciplines interested in understanding contemporary theories, practices, and critiques within this field, this work offers a comprehensive overview while also being accessible to those new to the subject.
