This chapter fills the gap in the judicialization of mega-political disputes before the Economic Community of West African States (ECOWAS) Community Court of Justice (ECOWAS Court). Judicialization of mega-political disputes in this Court has until now been understudied. Although the ECOWAS Court lacks an express mandate to adjudicate over political disputes, the Court has been innovative in assuming jurisdiction over mega-political disputes when these disputes are intertwined with actual or potential human rights violations. The Ugokwe doctrine, enunciated in the case of, Dr. Jerry Ugokwe v. The Federal Republic of Nigeria and Dr. Christian Okeke, established the “cause of action” for the judicialization of mega-political disputes before the ECOWAS Court. By examining cases that have largely remained obscure, the chapter uncovers the judicialization of political disputes, particularly of electoral cases, before the ECOWAS Court. Unlike the traditional scholarship that measures effectiveness based on compliance with the decisions of the courts, the chapter argues that the significance of the mega-political disputes judicialized before Africa’s regional courts derives from the instrumental objectives of the litigants. By incorporating the social, political, and economic contexts that gave rise to the francophone and anglophone cases analyzed, the chapter illuminates the judicialization of mega-political disputes in ways that are not wedded to the traditional analyses of the functions of regional economic courts.
