This book investigates the contemporary practices surrounding the international prosecution of sitting heads of states by the International Criminal Court (ICC). Through a specific focus on five contemporary case studies, the author reflects on the following: firstly, how the ICC itself has shaped the contemporary practices surrounding the prosecution of sitting heads of states; and secondly, the domestic and international "problematics" that have ensued from these practices. In doing so, Cacciatori argues that the international prosecution of sitting heads of states before the ICC constitutes "an imprudent exercise of Western humanitarianism". This, in turn, has not only worsened the domestic conditions of the countries subject to the ICC's investigations but in addition, it has also served to undermine the "very idea of cosmopolitan justice" in international politics.
