Appeals with leave
Section 242(2) · 1999 Constitution (2004 edition)
What Constitution says
(2) The Court of Appeal may dispose of any application for leave to appeal from any decision of the Federal High Court or a High Court in respect of any civil or criminal proceedings in which an appeal has been brought to the Federal High Court or a High Court from any other court after consideration of the record of the proceedings, if the Court of Appeal is of the opinion that the interests of justice do not require an oral hearing of the application.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
