Universal Jurisdiction Annual Review 2020: Terrorism and International Crimes: Prosecuting atrocities for what they are (UJAR) salutes the rise of universal jurisdiction cases worldwide. It also highlights an alarming legal trend: the prosecution of mass atrocities as terrorism, and not international crimes. The Universal Jurisdiction Annual Review is TRIAL International’s main legal publication. It has been researched and written by Valérie Paulet, in collaboration with REDRESS, the European Center for Constitutional and Human Rights (ECCHR) and the International Federation for Human Rights (FIDH). It benefited from the generous support of the City of Geneva, the Oak Foundation and the Taiwan Foundation for Democracy.
