The New Jersey Constitution of 1947 (Annotated) Art. IV, § III ¶ 4

4. Notwithstanding the provisions of paragraphs 1, 2, and 3 of this Section III, when the receipt by the Governor of the official decennial census of the United States for New Jersey occurs after February 15 of the year ending in one, following the year in which the census is taken, the commission shall certify the establishment of Senate and Assembly districts and the apportionment of Senators and members of the General Assembly to the Secretary of State after the November general election of that year ending in one, but not later than March 1 of the year ending in two. The commission shall begin conducting its business upon the receipt by the Governor of the official decennial census of the United States for New Jersey, and the eleventh member of the commission shall be appointed by the Chief Justice of the Supreme Court of New Jersey within one month of the Governor’s receipt of that census data. Such establishment and apportionment shall be used for the election of members of the Senate and General Assembly beginning with elections conducted in the year ending in three, and elections thereafter, and shall remain unaltered until the following decennial census of the United States for New Jersey shall have been received by the Governor.

The Senate and Assembly districts certified to the Secretary of State by the previous Apportionment Commission for the previous decade shall remain in effect in that year ending in one and in the year ending in two, and shall be used for legislative elections in those years.

For the election of members of the Senate and General Assembly occurring in November of that year ending in one, members shall be elected by the legally qualified voters of their district as drawn by the previous Apportionment Commission for the previous decade, for terms beginning at noon of the second Tuesday in January next following their election and ending at noon of the second Tuesday in January two years thereafter.
