Judicial powers
Section 6(4) · 1999 Constitution (2004 edition)
What Constitution says
(4) Nothing in the foregoing provisions of this section shall be construed as precluding:- (a) the National Assembly or any House of Assembly from establishing courts, other than those to which this section relates, with subordinate jurisdiction to that of a High Court; (b) the National Assembly or any House of Assembly, which does not require it, from abolishing any court which it has power to establish or which it has brought into being.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
