What Constitution says
(1) In exercising his powers under the foregoing provisions of this Chapter in respect of appointments to the offices of Justices of the Supreme court and Justices of the Court of Appeal, the President shall have regard to the need to ensure that there are among the holders of such offices persons learned in Islamic personal law and persons learned in Customary law.
