Existing law
Section 315(1) · 1999 Constitution (2004 edition)
What Constitution says
(1) Subject to the provisions of this Constitution, an existing law shall have effect with such modifications as may be necessary to bring it into conformity with the provisions of this Constitution and shall be deemed to be - (a) an Act of the National Assembly to the extent that it is a law with respect to any matter on which the National Assembly is empowered by this Constitution to make laws; and (b) a Law made by a House of Assembly to the extent that it is a law with respect to any matter on which a House of Assembly is empowered by this Constitution 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.
