Section 185 · 1999 Constitution (2004 edition)
What Constitution says
(1) A person elected to the office of the Governor of a State shall not begin to perform the functions of that until he has declared his assets and liabilities as prescribed in the Constitution and has subsequently taken and subscribed the Oath of Allegiance and oath of office prescribed in the Seventh Schedule to this Constitution. (2) The Oath of Allegiance and the oath of office shall be administered by the Chief Judge of the State or Grand Kadi of the Sharia Court of Appeal of the State, if any or President of the Customary Court of Appeal of the State, if any, or the person for the time being respectively appointed to exercise the functions of any of those offices in any State.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
