This book investigates the road map or the transitional justice mechanisms that the Ethiopian government chose to confront the gross human rights violations perpetrated under the 17 years’ rule of the Derg, the dictatorial regime that held power from 1974 to 1991. Furthermore, the author extensively examines the prosecution of politicide or genocide against political groups in Ethiopia. Dealing with the violent conflict, massacres, repressions and other mass atrocities of the past is necessary, not for its own sake, but to clear the way for a new beginning. In other words, ignoring gross human rights violations and attempting to close the chapter on an oppressive dictatorial past by choosing to let bygones be bygones, is no longer a viable option when starting on the road to a democratic future. For unaddressed atrocities and a sense of injustice would not only continue to haunt a nation but could also ignite similar conflicts in the future. So the question is what choices are available to the newly installed government when confronting the evils of the past. There are a variety of transitional mechanisms to choose from, but there is no “one size fits all” mechanism. Of all the transitional justice mechanisms, namely truth commissions, lustration, amnesty, prosecution, and reparation, the Ethiopian government chose prosecution as the main means for dealing with the horrendous crimes committed by the Derg regime. One of the formidable challenges for transitioning states in dealing with the crimes of former regimes is an inadequate legal framework by which to criminalize and punish egregious human rights violations. With the aim of examining whether or not Ethiopia had confronted this challenge, the book examines both Ethiopia’s legal framework regarding crimes under international law and individual criminal responsibility. This book will be of great relevance to academics and practitioners in the areas of genocide studies, international criminal law and transitional justice. Furthermore, students in the fields of international criminal law, transitional justice and human rights will find relevant information on the national prosecution of politicide in particular and the question of confronting the past in general.
