The power of the National Assembly to make law for the Federation as well as the extent of exercise of such power is provided for in Section 4 thus: “(1) The legislative powers of Federal Republic of Nigeria shall be vested in a National Assembly for the Federation which shall consist of a senate and a House of Representatives. (2) The National Assembly shall have power to make laws for the peace, order and good government of the Federation or any part thereof with respect to any matter included in the Exclusive list set out in Part I of the Second Schedule to this Constitution. The import of the above provision is that, in as much as the laws made by the National Assembly rank next in hierarchy to the Constitution, the provision of Section 4 (2) limits the powers of the National Assembly to make laws to those items set out in part I of the second schedule to the Constitution. Therefore, the power of the National Assembly to make law is not limitless but confined to those items listed in part I of the 2nd schedule of the Constitution i.e Exclusive list.
