Since 2008 the Ethiopian government has allocated vast tracts of land, particularly in the Gambella and Benishangul-Gumuz regions, to agricultural commercial actors with little or no participation from indigenous communities. The marginalization of indigenous peoples in this process primarily emerges from the government's very wide legislative discretionary power regarding decision-making in the exploitation of land. The government has invoked constitutional clauses relating to land ownership and its power to deploy land resources for the “common benefit” of the people, to assert the consistency of this discretionary power with the Ethiopian Constitution. This article posits that the legislative and practical measures taken by the government that marginalize these indigenous peoples in decisions affecting the utilization of land resources are incompatible with their constitutional right to self-determination. Further, it posits that the government's use of the constitution to justify its wide discretionary power in the decision-making process relating to land exploitation is based on a misreading of the constitution.
