Notwithstanding any other provision of law or regulation, if the Parole Board adopts a rule or regulation requiring the concurrence of four or more members of the Parole Board to grant discretionary parole or conditional release, in the event that there are less than four members but at least three members on the Parole Board, then such requirement shall be satisfied upon a unanimous vote of all members on the Parole Board.
