The New Jersey Constitution of 1947 (Annotated) Art. II, § II, ¶ 1

1. (a) After each federal census taken in a year ending in zero, the Congressional districts shall be established by the New Jersey Redistricting Commission.

The commission shall consist of 13 members, none of whom shall be a member or employee of the Congress of the United States.  The members of the commission shall be appointed with due consideration to geographic, ethnic and racial diversity and in the manner provided herein.

(b) There shall first be appointed 12 members as follows:

(c) There shall then be appointed one member, to serve as an independent member, who shall have been for the preceding five years a resident of this State, but who shall not during that period have held public or party office in this State.

The independent member shall be appointed upon the vote of at least seven of the previously appointed members of the commission on or before July 15 of each year ending in one, and those members shall certify that appointment to the Secretary of State on or before July 20 of that year.  If the previously appointed members are unable to appoint an independent member within the time allowed therefor, they shall so certify to the Supreme Court not later than that July 20 and shall include in that certification the names of the two persons who, in the members' final vote upon the appointment of the independent member, received the greatest number of votes.  Not later than August 10 following receipt of that certification, the Supreme Court shall by majority vote of its full authorized membership select, of the two persons so named, the one more qualified by education and occupational experience, by prior public service in government or otherwise, and by demonstrated ability to represent the best interest of the people of this State, to be the independent member.  The Court shall certify that selection to the Secretary of State not later than the following August 15.

(d) Vacancies in the membership of the commission occurring prior to the certification by the commission of Congressional districts or during any period in which the districts established by the commission may be or are under challenge in court shall be filled in the same manner as the original appointments were made within five days of their occurrence.  In the case of a vacancy in the membership of the independent member, if the other members of the commission are unable to fill that vacancy within that five-day period, they shall transmit certification of such inability within three days of the expiration of the period to the Supreme Court, which shall select the person to fill the vacancy within five days of receipt of that certification.
