Notwithstanding any other provision of the law, whenever a vacancy occurs on a state board or commission, or a seat on a board or commission is abolished by statute, the board or commission shall notify the appropriate appointing authority of this occurrence and the appropriate appointing authority shall notify the person occupying the vacated or abolished seat that the person may no longer serve on the board or commission. Except as provided in Section 1774, the person occupying the vacated or abolished seat on the board or commission shall continue to serve until notified by the appropriate appointing authority.
