What Constitution says
(3) A person shall not be qualified to hold office as a Kadi of the Sharia Court of Appeal of a State unless - (a) he is a legal practitioner in Nigeria and has been so qualified for a period of not less than ten years and has obtained a recognised qualification in Islamic law from an institution acceptable to the National Judicial Council; or (b) he has attended and has obtained a recognised qualification in Islamic law from an institution approved by the National Judicial council and has held the qualification for a period of not less than ten years; and (i) he either has considerable experience in the practice of Islamic law, or (ii) he is a distinguished scholar of Islamic law.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
