Article III, § 4 — Readjustments and reapportionments; when federal census to control

(a) Except as herein otherwise provided, the federal census taken in the year nineteen hundred thirty and each federal census taken decennially thereafter shall be controlling as to the number of inhabitants in the state or any part thereof for the purposes of the apportionment of members of assembly and readjustment or alteration of senate and assembly districts next occurring, in so far as such census and the tabulation thereof purport to give the information necessary therefor. The legislature, by law, shall provide for the making and tabulation by state authorities of an enumeration of the inhabitants of the entire state to be used for such purposes, instead of a federal census, if the taking of a federal census in any tenth year from the year nineteen hundred thirty be omitted or if the federal census fails to show the number of aliens or Indians not taxed. If a federal census, though giving the requisite information as to the state at large, fails to give the information as to any civil or territorial divisions which is required to be known for such purposes, the legislature, by law, shall provide for such an enumeration of the inhabitants of such parts of the state only as may be necessary, which shall supersede in part the federal census and be used in connection therewith for such purposes. The legislature, by law, may provide in its discretion for an enumeration by state authorities of the inhabitants of the state, to be used 4 State Law §123 sets forth current number of senators. 5 State Law §124 currently sets forth 63 senate districts. for such purposes, in place of a federal census, when the return of a decennial federal census is delayed so that it is not available at the beginning of the regular session of the legislature in the second year after the year nineteen hundred thirty or after any tenth year therefrom, or if an apportionment of members of assembly and readjustment or alteration of senate districts is not made at or before such a session. At the regular session in the year nineteen hundred thirty-two, and at the first regular session after the year nineteen hundred forty and after each tenth year therefrom the senate districts shall be readjusted or altered, but if, in any decade, counting from and including that which begins with the year nineteen hundred thirty- one, such a readjustment or alteration is not made at the time above prescribed, it shall be made at a subsequent session occurring not later than the sixth year of such decade, meaning not later than nineteen hundred thirty-six, nineteen hundred forty-six, nineteen hundred fifty-six, and so on; provided, however, that if such districts shall have been readjusted or altered by law in either of the years nineteen hundred thirty or nineteen hundred thirty-one, they shall remain unaltered until the first regular session after the year nineteen hundred forty. No town, except a town having more than a full ratio of apportionment, and no block in a city inclosed by streets or public ways, shall be divided in the formation of senate districts. In the reapportionment of senate districts, no district shall contain a greater excess in population over an adjoining district in the same county, than the population of a town or block therein adjoining such district. Counties, towns or blocks which, from their location, may be included in either of two districts, shall be so placed as to make said districts most nearly equal in number of inhabitants, excluding aliens. No county shall have four or more senators unless it shall have a full ratio for each senator. No county shall have more than one-third of all the senators; and no two counties or the territory thereof as now organized, which are adjoining counties, or which are separated only by public waters, shall have more than one-half of all the senators. (b) The independent redistricting commission established pursuant to section five-b of this article shall prepare a redistricting plan to establish senate, assembly, and congressional districts every ten years commencing in two thousand twenty-one, and shall submit to the legislature such plan and the implementing legislation therefor on or before January first or as soon as practicable thereafter but no later than January fifteenth in the year ending in two beginning in two thousand twenty-two. The redistricting plans for the assembly and the senate shall be contained in and voted upon by the legislature in a single bill, and the congressional district plan may be included in the same bill if the legislature chooses to do so. The implementing legislation shall be voted upon, without amendment, by the senate or the assembly and if approved by the first house voting upon it, such legislation shall be delivered to the other house immediately to be voted upon without amendment. If approved by both houses, such legislation shall be presented to the governor for action. If either house shall fail to approve the legislation implementing the first redistricting plan, or the governor shall veto such legislation and the legislature shall fail to override such veto, each house or the governor if he or she vetoes it, shall notify the commission that such legislation has been disapproved. Within fifteen days of such notification and in no case later than February twenty-eighth, the redistricting commission shall prepare and submit to the legislature a second redistricting plan and the necessary implementing legislation for such plan. Such legislation shall be voted upon, without amendment, by the senate or the assembly and, if approved by the first house voting upon it, such legislation shall be delivered to the other house immediately to be voted upon without amendment. If approved by both houses, such legislation shall be presented to the governor for action. If either house shall fail to approve the legislation implementing the second redistricting plan, or the governor shall veto such legislation and the legislature shall fail to override such veto, each house shall introduce such implementing legislation with any amendments each house of the legislature deems necessary. All such amendments shall comply with the provisions of this article. If approved by both houses, such legislation shall be presented to the governor for action. All votes by the senate or assembly on any redistricting plan legislation pursuant to this article shall be conducted in accordance with the following rules: (1) In the event that the speaker of the assembly and the temporary president of the senate are members of two different political parties, approval of legislation submitted by the independent redistricting commission pursuant to subdivision (f) of section five-b of this article shall require the vote in support of its passage by at least a majority of the members elected to each house. (2) In the event that the speaker of the assembly and the temporary president of the senate are members of two different political parties, approval of legislation submitted by the independent redistricting commission pursuant to subdivision (g) of section five-b of this article shall require the vote in support of its passage by at least sixty percent of the members elected to each house. (3) In the event that the speaker of the assembly and the temporary president of the senate are members of the same political party, approval of legislation submitted by the independent redistricting commission pursuant to subdivision (f) or (g) of section five-b of this article shall require the vote in support of its passage by at least two-thirds of the members elected to each house. (c) Subject to the requirements of the federal constitution and statutes and in compliance with state constitutional requirements, the following principles shall be used in the creation of state senate and state assembly districts and congressional districts: (1) When drawing district lines, the commission shall consider whether such lines would result in the denial or abridgement of racial or language minority voting rights, and districts shall not be drawn to have the purpose of, nor shall they result in, the denial or abridgement of such rights. Districts shall be drawn so that, based on the totality of the circumstances, racial or minority language groups do not have less opportunity to participate in the political process than other members of the electorate and to elect representatives of their choice. (2) To the extent practicable, districts shall contain as nearly as may be an equal number of inhabitants. For each district that deviates from this requirement, the commission shall provide a specific public explanation as to why such deviation exists. (3) Each district shall consist of contiguous territory. (4) Each district shall be as compact in form as practicable. (5) Districts shall not be drawn to discourage competition or for the purpose of favoring or disfavoring incumbents or other particular candidates or political parties. The commission shall consider the maintenance of cores of existing districts, of pre-existing political subdivisions, including counties, cities, and towns, and of communities of interest. (6) In drawing senate districts, towns or blocks which, from their location may be included in either of two districts, shall be so placed as to make said districts most nearly equal in number of inhabitants. The requirements that senate districts not divide counties or towns, as well as the 'block-on-border' and 'town-on-border' rules, shall remain in effect. During the preparation of the redistricting plan, the independent redistricting commission shall conduct not less than one public hearing on proposals for the redistricting of congressional and state legislative districts in each of the following (i) cities: Albany, Buffalo, Syracuse, Rochester, and White Plains; and (ii) counties: Bronx, Kings, New York, Queens, Richmond, Nassau, and Suffolk. Notice of all such hearings shall be widely published using the best available means and media a reasonable time before every hearing. At least thirty days prior to the first public hearing and in any event no later than September fifteenth of the year ending in one or as soon as practicable thereafter, the independent redistricting commission shall make widely available to the public, in print form and using the best available technology, its draft redistricting plans, relevant data, and related information. Such plans, data, and information shall be in a form that allows and facilitates their use by the public to review, analyze, and comment upon such plans and to develop alternative redistricting plans for presentation to the commission at the public hearings. The independent redistricting commission shall report the findings of all such hearings to the legislature upon submission of a redistricting plan. (d) The ratio for apportioning senators shall always be obtained by dividing the number of inhabitants, excluding aliens, by fifty, and the senate shall always be composed of fifty members, except that if any county having three or more senators at the time of any apportionment shall be entitled on such ratio to an additional senator or senators, such additional senator or senators shall be given to such county in addition to the fifty senators, and the whole number of senators shall be increased to that extent. The senate districts, including the present ones, as existing immediately before the enactment of a law readjusting or altering the senate districts, shall continue to be the senate districts of the state until the expirations of the terms of the senators then in office, except for the purpose of an election of senators for full terms beginning at such expirations, and for the formation of assembly districts. (e) The process for redistricting congressional and state legislative districts established by this section and sections five and five-b of this article shall govern redistricting in this state except to the extent that a court is required to order the adoption of, or changes to, a redistricting plan as a remedy for a violation of law. A reapportionment plan and the districts contained in such plan shall be in force until the effective date of a plan based upon the subsequent federal decennial census taken in a year ending in zero unless modified pursuant to court order.
