(a)
(1) Whenever any laws of this state shall provide for the appointment of members of boards and commissions from each congressional district, they shall be deemed to mean the congressional districts of the state existing at the time of the appointment, and not the congressional districts existing at the time of the passage of those laws.
(2) Whenever the total membership of any board or commission shall exceed the number of congressional districts from which appointments are to be made, the members in excess of congressional district appointees shall be appointed from the state at large.
(b) If the number of congressional districts in this state shall be reduced to fewer than six (6), the members of all boards and commissions of this state, including the Legislative Council and the Legislative Joint Auditing Committee, who are selected or apportioned on the basis of congressional districts, shall continue to be selected or apportioned upon the basis of the six (6) congressional districts, as established by Act 297 of 1951 [repealed], until otherwise specifically provided by law.
