The Constitution has vested in the National Assembly the power to make laws for the peace, order and good governance of the Federation. The Assembly also has broad oversight functions and is therefore empowered to establish committees of its members to scrutinize bills and the conduct of government institutions and officials.
The Constitution confers exclusive powers to the Senate among them the power to scrutinize and confirm major appointments of the executive. It is, however, specific about the appointments to be confirmed. They are those of the Ministers, Special Advisers, Ambassadors, top Judicial Officers heading specified levels of courts, the Auditor-General of the Federation, and the Chairmen and Members of the vital National Commissions.
