43. In the case of any waqf of which there is no mutawalli or where there appears to the Administrator to be an impediment to the appointment of a mutawalli in terms of the deed of waqf or where the successor to the office of mutawalli is a minor, a person of unsound mind or a person adjudged insolvent by a competent Court of law, the Administrator may, for such period as he deems fit, appoint a person to act as mutawalli with notice to all the persons interested in the waqf. Any person aggrieved by such an appointment may, within three months from the date of the receipt of the notice, appeal to the District Judge; and the decision of the District Judge shall be final.
