If the General Appropriations Act does not prescribe the amount of per diem to which a member of a state board or commission is entitled by law, the law prescribing the amount of per diem is not suspended by this Act. If a law imposes a limit on the number of days for which a member of a state board or commission is entitled to claim per diem, the limit is not suspended by this Act. The items of appropriation for per diem of board or commission members include compensatory per diem only. No employee paid from funds appropriated by this Act shall be paid both a salary and compensatory per diem for concurrent service as a state employee and as a board or commission member. Acts 1985, 69th Leg.
Similar considerations apply to the case at hand.
