Decentralisation and constitutionalism in Africa: A theoretical exploration for sustainable distributive justice

Central to the problem of most of the states in Africa as a whole and Nigeria in particular is the excessive centralization of the federal system. The centralized federalism denied the opportunity for self-expression, autonomy and by extension prevented avenues for negotiations towards attaining equity and justice. Similar to this is the defect on the constitution which is meant to define what is right by creating a...
