Section 5(1) · 1999 Constitution (2004 edition)
What Constitution says
(1) Subject to the provisions of this Constitution, the executive powers of the Federation: (a) shall be vested in the President and may subject as aforesaid and to the provisions of any law made by the National Assembly, be exercised by him either directly or through the Vice-President and Ministers of the Government of the Federation or officers in the public service of the Federation; and (b) shall extend to the execution and maintenance of this Constitution, all laws made by the National Assembly and to all matters with respect to which the National Assembly has, for the time being, power to make laws.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
