The Senate is the upper house of the Nigeria’s bicameral legislature, the National Assembly of Nigeria.
The Constitution confers exclusive powers to the Senate. Among them is 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.
Bills may be introduced in any chamber of the National Assembly. However,the Nigerian constitution provides that money bills (Revenue and Appropriation bills) must originate in the House of Representatives, although the approval of both the Senate and the House of Representatives is required for any bill, including money bills, to become law.
Checks and Balances
The constitution provides several unique functions for the Senate that form its ability to “check and balance” other elements of the Federal Government of Nigeria. These include the requirement that the Senate may advice and must consent to some of the President’s government appointments; also the Senate must consent to all treaties with foreign governments and it tries all impeachments.
