From Advisory to Oversight: The Development of the Nigerian Legislature, 1914 to 1999

The Nigerian legislature has undergone a profound transmogrification from the colonial constitutions of 1914, 1922, 1946, 1951 and 1954, to the First Republic Constitutions of 1960 and 1963, the Second Republic Constitution of 1979, to the Fourth Republic Constitution of 1999. The military interregnum of 1966 to 1979 and 1983 to 1999, which occasioned the 1989 and 1995 Constitutions that were not promulgated, also precipitated changes in the development of Nigeria’s legislature. These mirrored the turbulent journey of the Country’s legislature from colonial dependency to the faltering steps towards nationhood. From its origin as a colonial tool for administrative convenience through to its emergence as a cornerstone of democratic governance, the legislative arm has shifted between various models of representation, majorly from the fusion of powers under the parliamentary to the separation of powers under the presidential models. This article examines the historical transition of the Nigerian legislature from a subservient advisory body with no legislative autonomy to a robust, independent, co-equal arm` of government vested with expansive oversight powers under the 1999 Constitution. Through the doctrinal analysis of successive constitutional frameworks, this paper identified the transformative identity of Nigeria’s legislature from its passive collaboration with the executive to a vital mechanism for democratic accountability, national integration, and constitutional checks and balances.
