In the event of a vacancy that qualifies for an appointment under paragraph 2 or 3 of this subsection, the Speaker of the House and the President Pro Tempore shall have alternating appointments; provided, however, the Speaker of the House shall make the initial appointment.
When congressional districts are redrawn, each member appointed and confirmed by the Senate, if applicable, prior to July 1 of the year in which such modification becomes effective shall complete the current term of office, and appointments made and confirmed by the Senate, if applicable, after July 1 of the year in which such modification becomes effective shall be based on the redrawn districts. Appointments made after July 1 of the year in which such modification becomes effective shall be from any redrawn districts which are not represented by a board member until such time as each of the modified congressional districts is represented by a board member.
