Legislative powers
Section 4(5) · 1999 Constitution (2004 edition)
What Constitution says
(5) If any Law enacted by the House of Assembly of a State is inconsistent with any law validly made by the National Assembly, the law made by the National Assembly shall prevail, and that other Law shall, to the extent of the inconsistency, be void.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
