The board's approval of a structured settlement shall be final at the time the approval is signed by the board unless the board has received a request in writing prior to entry of the approval order that one or more parties to the agreement wishes to withdraw their consent to the settlement, and the board permits the withdrawal of such consent. Any such written request to the board for permission to withdraw consent to a settlement must fully set out the reason or reasons for such request (effective 1987).
