Original jurisdiction (Supreme Court)
Section 232(2) · 1999 Constitution (2004 edition)
What Constitution says
(2) In addition to the jurisdiction conferred upon it by subsection (1) of this section, the Supreme Court shall have such original jurisdiction as may be conferred upon it by any Act of the National Assembly. Provided that no original jurisdiction shall be conferred upon the Supreme Court with respect to any criminal matter.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
