The subject of revolutionary overthrow of constitutional orders in Africa is at the intersection of three disciplines: jurisprudence and legal philosophy, constitutional law and power politics, and civil-military relations, that is, military security policy which is one aspect of national security policy. The subject is of interest in at least four ways. It problematizes the inescapable question of governance in the African continent. It challenges the democratization agenda in Africa - how does one democratize not only political governance but also the instruments of violence in the state? It also challenges African constitutional lawyers and policy makers to seek a constitutional model that addresses the enduring menace of the power of the gun in African affairs and the changing role of the military in African politics. Finally, it underscores concerns about sovereignty and national security. This book contributes to a fuller understanding of the coup syndrome in African. To this end, it vigorously interrogates the place of coups in the governance of Africa, and explores the relevance of Kelsen's theory of revolutionary legality in the context of coup d'états in Africa. It is a major contribution by a leading thinker in the field.
