Sharon Weill, Kim Thuy Seelinger and Kerstin Bree Carlson have edited a book about the trial in Senegal of Chadian former president Hissene Habré for crimes against humanity, war crimes and torture. The book, entitled The President on Trial: Prosecuting Hissène Habré and published by Oxford University Press in May 2020 is a socio-legal study of the pursuit of Hissene Habré, which began when he left power in 1990 and concluded with the trial judgment in 2017. By taking the pursuit of Habré as its subject, and by building the narration through the experience of a wide spectrum of actors implicated in this process, the book contributes methodologically to the study of global justice by showcasing how actors are integral to how we understand a process.
