This concluding chapter argues that the relationship between decentralisation and constitutionalism in Africa is close and symbiotic, with the one influencing the other in ways that can be either supportive or destructive. The fulfilment of decentralisation depends on constitutionalism. Similarly, to the extent that decentralisation gives expression to constitutionalism by deepening democracy, limiting central power, and advancing development, constitutionalism is bolstered by decentralisation. As the absence of constitutionalism is fatal for decentralisation, so, too, can sub-national governments be destructive of constitutionalism. A mutually beneficial relationship is thus the ultimate goal. It is the very idea of controlling individual greed for power and wealth and cooperating collectively with others for a greater good.
