Appellate jurisdiction (Supreme Court)
Section 233(5) · 1999 Constitution (2004 edition)
What Constitution says
(5) Any right of appeal to the supreme Court from the decisions of the Court of Appeal conferred by this section shall be exercisable in the Case of civil proceedings at the instance of a party thereto, or with the leave of the Court of Appeal or the Supreme Court at the instance of an person having an interest in the matter, and in the case of criminal proceedings at the instance of an accused person, or subject to the provisions of this Constitution and any powers conferred upon the Attorney-General of the Federation or the Attorney-General of a state to take over and continue or to discontinue such proceedings, at the instance of such other authorities or persons as may be prescribed.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
