Either the assembly or the senate shall bring the bill to a vote expeditiously, but not less than 7 days after the commission report under s. 13.49 (3) (d) 2. is received and made available to the members of the legislature. The vote shall be under a procedure or rule permitting no amendments.

The legislative reference bureau shall deliver the bills to the majority leader of the senate and the speaker of the assembly no later than 21 days after the date of the vote by which the senate or the assembly failed to approve the bill submitted under sub.

Any bill delivered by the legislative reference bureau under this subsection shall be expeditiously introduced and brought to a vote not less than 7 days after the date of introduction, in the same manner as prescribed for the bill required under sub.

(2). Any bill delivered by the legislative reference bureau under this subsection shall be expeditiously introduced and brought to a vote not less than 7 days after the date of introduction and shall be subject to amendment in the same manner as other bills. Any bill delivered under this subsection, and any amendment to such a bill, may be passed only with the approval of three-fourths of all the members elected in each house.

SB389,10,13 (4) Notwithstanding subs. (1) to (3):

SB389,10,23 (a) If certified federal census data that is sufficient to permit preparation of a congressional redistricting plan becomes available at an earlier time than the population data needed to permit preparation of a legislative redistricting plan in accordance with s. 4.007, the legislative reference bureau shall so inform the majority leader of the senate and the speaker of the assembly. If the majority leader of the senate and the speaker of the assembly jointly direct, the legislative reference bureau shall prepare a separate bill establishing congressional districts and deliver it separately from the bill establishing legislative districts. The legislature shall proceed to consider the congressional redistricting bill in substantially the manner prescribed by subs. (1) to (3).

SB389,11,8 (b) If the population data for legislative redistricting that the U.S. bureau of the census is required to provide this state under P.L. 94-171 and, if used by the legislative reference bureau, the corresponding topologically integrated geographic encoding and referencing data file for that population data are not available to the legislative reference bureau on or before April 1 of the first year following the decennial federal census, the deadlines set forth in this section shall be extended by a number of days equal to the number of days after April 1 of the first year following the decennial federal census that the population data and the topologically integrated geographic encoding and referencing data file for legislative redistricting become available.

SB389,11,12 4.007 Redistricting standards. (1) Legislative and congressional districts shall be established on the basis of population requirements imposed under the Wisconsin Constitution and the U.S. Constitution and requirements imposed under Section 2 of the Voting Rights Act.

SB389,11,24 (2) Senate and assembly districts, respectively, shall satisfy the population standards established in this subsection. The quotient, obtained by dividing the sum of the absolute values of the deviations of all district populations from the applicable ideal district population by the number of districts established, may not exceed 1 percent of the applicable ideal district population, unless necessary to maintain compliance with Section 2 of the Voting Rights Act. For purposes of this subsection, the ideal district population is determined by dividing the population of the state reported in the most recent federal decennial census by the number of districts to be established. No senate district may have a population that exceeds that of any other senate district by more than 10 percent and no assembly district may have a population that exceeds that of any other assembly district by more than 10 percent, unless necessary to maintain compliance with Section 2 of the Voting Rights Act.

SB389,12,6 (3) Congressional districts shall each have a population as nearly equal as practicable to the ideal district population, derived as prescribed in sub. (2), while maintaining compliance with Section 2 of the Voting Rights Act. No congressional district may have a population that varies by more than 1 percent from the applicable ideal district population, unless necessary to comply with Section 2 of the Voting Rights Act.

SB389,12,14 (4) District boundaries shall coincide with ward boundaries and, to the extent consistent with sub. (1), shall coincide with the boundaries of political subdivisions. The number of political subdivisions divided among more than one district shall be as small as possible. When there is a choice among political subdivisions to divide, the more populous political subdivisions shall be divided before the less populous, except that this requirement does not apply to a legislative district boundary drawn along a county boundary which passes through a city with territory in more than one county.

SB389,12,16 (5) Districts shall be composed of convenient contiguous territory. Areas which meet only at the points of adjoining corners are not contiguous.

SB389,12,20 (6) Districts shall not be drawn with the intent or result of denying or abridging the equal opportunity of racial or language minorities to participate in the political process or diminishing their ability to elect representatives of their choice, whether by themselves or by voting in concert with other persons.
