3subchapter I of chapter 4 [precedes 4.001]; and to create 13.49 of the statutes;

Analysis by the Legislative Reference Bureau
Currently, under the state constitution, the legislature is directed to redistrict
legislative districts according to the number of inhabitants at its next session
following each decennial federal census. At the same intervals, the legislature also
reapportions congressional districts in this state pursuant to federal law. Under
current state law, following each decennial federal census, most municipalities are
also required to divide their territory into wards. With limited exceptions, wards are
required to consist of one or more whole, contiguous census blocks (the smallest
geographic units for which census results are available). Traditionally, the
legislature has used municipal wards to construct legislative and congressional
districts, although the legislature may adjust the boundaries of a municipal ward
and use the revised ward boundaries instead. Legislative and congressional
redistricting plans enacted pursuant to this procedure are used to elect members of
the legislature and members of Congress in the fall of the second year following the
year of the census.
This bill creates a new procedure for the preparation of legislative and
congressional redistricting plans. The bill directs the Legislative Reference Bureau
(LRB) to draw redistricting plans based upon standards specified in the bill and

establishes a Redistricting Advisory Commission to perform certain tasks in the
redistricting process. The bill also makes various other changes to the laws
governing redistricting. Significant aspects of the bill include:
Redistricting standards
Under the bill, a redistricting plan drawn by the LRB must satisfy several
criteria, including:
1. The plan must be based on population requirements imposed under the
Wisconsin Constitution and the U.S. Constitution and requirements imposed under
Section 2 of the federal Voting Rights Act, which, among other things, generally
prohibits redistricting plans from abridging the right to vote on account of race or
color or because a person is a member of a language minority group.
2. The senate and assembly districts established in the plan must satisfy equal
population standards specified in the bill. Among other things, no senate district
may have a population which exceeds that of any other senate district by more than
10 percent and no assembly district may have a population which 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. Congressional districts
established in the plan must each have a population as nearly equal as practicable
to the ideal population for such districts, while maintaining compliance with Section
2 of the Voting Rights Act.
3. District boundaries under the plan must coincide with municipal ward
boundaries and, to the extent consistent with the Wisconsin Constitution, the U.S.
Constitution, and Section 2 of the Voting Rights Act, must coincide with the
boundaries of political subdivisions. The number of political subdivisions divided
among more than one district must be as small as possible and, with limited
exceptions, if there is a choice among political subdivisions to divide, the more
populous political subdivisions shall be divided before the less populous.
4. Districts must be composed of convenient contiguous territory. Under the
bill, areas which meet only at the points of adjoining corners are not contiguous.
5. To the extent consistent with the requirements described in items 1. to 3.,
districts must be compact. The bill also specifies how compactness is to be measured.
6. In preparing the plan, the LRB must be strictly nonpartisan. No district may
be drawn for the purpose of favoring a political party, incumbent legislator or
member of Congress, or other person or group, or, except to the extent necessary to
meet the requirements described in item 1., for the purpose of augmenting or diluting
the voting strength of a language or racial minority group. The LRB may not use
residence addresses of incumbent legislators or members of Congress, political
affiliations of registered voters, previous election results, or, except as necessary to
meet the requirements described in item 1., demographic information.
7. The number of assembly districts may not be less than 54 nor more than 100.
The number of senate districts may not be more than one-third nor less than
one-fourth of the number of assembly districts. Each senate district must contain
only whole assembly districts and, with certain exceptions, each congressional
district may contain only whole senate districts, to the extent possible.

Redistricting Advisory Commission
The bill assigns several tasks to the Redistricting Advisory Commission,
including:
1. If requested to do so by the LRB, the commission must provide direction to
the LRB concerning any decision the LRB must make in preparing a redistricting
plan for which no clearly applicable guideline is provided under the bill.
2. The commission must make available to the public at the earliest feasible
time copies of any redistricting bill delivered by the LRB to the legislature, as
provided under this bill, maps illustrating the redistricting bill, a summary of the
standards applicable to the LRB for development of the plan in the redistricting bill,
and a statement of the population of each district created in the plan and the relative
deviation of each district population from the ideal district population.
3. The commission must conduct at least three public hearings on a
redistricting bill delivered by the LRB to the legislature, as provided under this bill,
unless the redistricting bill represents a plan drawn in response to a redistricting bill
that was previously delivered to the legislature and rejected by at least one house.
The commission must submit a report to the legislature summarizing information
and testimony received by the commission at the hearings. The report may also
include any comments and conclusions which the commission's members deem
appropriate concerning the information and testimony received at the hearings or
otherwise presented to the commission.
The bill also permits the commission to establish policies limiting the
information that the LRB may provide to persons outside of LRB staff concerning any
redistricting plan drawn by the LRB, except that any such policy does not apply to
population data furnished to the LRB by the U.S. Bureau of the Census or to a
redistricting plan after a bill embodying that plan is delivered by the LRB to the
legislature as required under this bill.
Under the bill, the Redistricting Advisory Commission must be created not
later than February 15 of the first year following the decennial federal census and
terminates upon satisfying its duties, until a new Redistricting Advisory
Commission is created for the next round of legislative and congressional
redistricting. The commission consists of five members. The speaker and minority
leader of the assembly and the majority and minority leaders of the senate must each
appoint one person to serve on the commission. Within 30 days after the fourth
commission member is appointed, but not later than February 15 of the first year
following the decennial federal census, the four commission members so appointed
must select the fifth commission member, who serves as chairperson. The bill
prohibits all of the following individuals from being a commission member:
individuals who are not eligible electors of this state at the time of the appointment,
individuals who hold partisan public office or political party office, and individuals
who are a relative of or are employed by a member of the legislature or of Congress,
or are employed directly by the legislature or Congress.
Redistricting process
The bill requires the LRB to perform certain tasks in preparation for drawing
congressional and legislative redistricting plans on the basis of each federal

decennial census. For example, as soon as possible after receiving from the U.S.
Bureau of the Census the population data needed for legislative redistricting, the
LRB must use that data to assign a population figure to geographic or political units
to facilitate the drawing of redistricting plans. Typically, this data is available on or
about April 1 of the first year following the decennial federal census. The LRB must
also prepare and publish an analysis describing the population of current legislative
and congressional districts and the extent to which the districts may violate the
redistricting standards described above. In addition, as municipalities complete
their ward plans (typically, by October of the first year following the decennial
federal census), the LRB must assign a population figure based upon certified federal
census data to each municipal ward, for use in drawing redistricting plans.
Not later than January 1 of the second year following the decennial federal
census, the LRB must deliver to the majority leader of the senate and speaker of the
assembly identical bills embodying a plan of legislative and congressional
districting, drawn in accordance with the standards described above. The bill
further specifies a procedure that the legislature must follow in considering the bills,
although that procedure is not enforceable by the courts. The bill requires either the
assembly or the senate to bring the bill to a vote expeditiously, but not less than seven
days after the report of the Redistricting Advisory Commission is received and made
available to the members of the legislature. The vote must be under a procedure or
rule permitting no amendments except those of a purely corrective nature. If the bill
is approved by the first house in which it is considered, the bill must expeditiously
be brought to a vote in the second house under a similar procedure or rule.
If neither of the bills delivered by the LRB is approved by both the assembly and
the senate, the chief clerk of the house that failed to approve the bill must transmit
to the LRB information which that house may direct regarding reasons why the plan
was not approved. The LRB must then prepare identical bills embodying a second
plan of legislative and congressional redistricting, taking into account the reasons
transmitted to the LRB, insofar as it is possible to do so while complying with the
standards described above. The LRB must deliver the bill 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 initially
submitted. This second bill must be expeditiously introduced and brought to a vote
not less than seven days after the date of introduction, in the same manner as
prescribed for the initial bill.
If the second bill is similarly rejected by at least one house, the same procedure
applies, except that the third bill is subject to amendment in the same manner as
other bills.
The bill also provides exceptions to this process to account for variations in the
timing of the release of federal census data.
Required contents of redistricting bills
The LRB must ensure that each bill embodying a redistricting plan it draws
contains specified conventions to apply wherever territory in a plan is described by
geographic boundaries. Also, each such bill must provide that the bill first applies,
with respect to regular elections, to offices filled at the next occurring general

election and, with respect to special or recall elections, to offices filled or contested
on or after the date of the next occurring general election.
Challenge based on population inequality
If an action is brought challenging a legislative redistricting plan adopted
under the procedure established in the bill on the basis of an excessive population
variance among senate or assembly districts, the legislature has the burden of
justifying any variance in excess of 10 percent between the population of a senate or
assembly district and the applicable ideal district population. If an action is brought
challenging a congressional redistricting plan adopted under the procedure
established in the bill on the basis of an excessive population variance among
congressional districts, the legislature has the burden of justifying any variance in
excess of 1 percent between the population of a congressional district and the
applicable ideal district population.
For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.

8encoding and referencing data file for that population data are not available to the
9legislative reference bureau on or before April 1 of the first year following the
10decennial federal census, the deadlines set forth in this section shall be extended by
11a number of days equal to the number of days after April 1 of the first year following
12the decennial federal census that the population data and the topologically
13integrated geographic encoding and referencing data file for legislative redistricting
14become available.
SB58,10,18 154.007 Redistricting standards. (1) Legislative and congressional districts
16shall be established on the basis of population requirements imposed under the
17Wisconsin Constitution and the U.S. Constitution and requirements imposed under
18Section 2 of the Voting Rights Act.
SB58,11,6 19(2) Senate and assembly districts, respectively, shall satisfy the population
20standards established in this subsection. The quotient, obtained by dividing the sum
21of the absolute values of the deviations of all district populations from the applicable
22ideal district population by the number of districts established, may not exceed 1
23percent of the applicable ideal district population, unless necessary to maintain
24compliance with Section 2 of the Voting Rights Act. For purposes of this subsection,
25the ideal district population is determined by dividing the number of districts to be

1established into the population of the state reported in the most recent federal
2decennial census. No senate district may have a population which exceeds that of
3any other senate district by more than 10 percent and no assembly district may have
4a population which exceeds that of any other assembly district by more than 10
5percent, unless necessary to maintain compliance with Section 2 of the Voting Rights
6Act.
SB58,11,12 7(3) Congressional districts shall each have a population as nearly equal as
8practicable to the ideal district population, derived as prescribed in sub. (2), while
9maintaining compliance with Section 2 of the Voting Rights Act. No congressional
10district may have a population which varies by more than 1 percent from the
11applicable ideal district population, unless necessary to comply with Section 2 of the
12Voting Rights Act.
SB58,11,20 13(4) District boundaries shall coincide with ward boundaries and, to the extent
14consistent with sub. (1), shall coincide with the boundaries of political subdivisions.
15The number of political subdivisions divided among more than one district shall be
16as small as possible. When there is a choice among political subdivisions to divide,
17the more populous political subdivisions shall be divided before the less populous,
18except that this requirement does not apply to a legislative district boundary drawn
19along a county boundary which passes through a city with territory in more than one
20county.
SB58,11,22 21(5) Districts shall be composed of convenient contiguous territory. Areas which
22meet only at the points of adjoining corners are not contiguous.
SB58,11,23 23(6) (a) In this subsection:
SB58,12,724 1. "Geographic unit center" means that point within a population data unit
25approximately equidistant from the northern and southern extremities and also

1approximately equidistant from the eastern and western extremities of the
2population data unit. This point shall be determined by visual observation of a map
3of the population data unit, unless it is otherwise determined within the context of
4an appropriate coordinate system developed by the federal government or another
5source that the legislative reference bureau determines is qualified and objective and
6is obtained for use in this state with prior approval of the joint committee on
7legislative organization.
SB58,12,118 2. "Population data unit" means a ward, census enumeration district, block, or
9other unit of territory having clearly identified geographic boundaries and for which
10a total population figure is included in or can be derived directly from certified
11federal census data.
SB58,12,1712 3. "X-coordinate" means the relative location of a point along the east–west
13axis of the state. Unless otherwise measured within the context of an appropriate
14coordinate system obtained for use as permitted by subd. 1., the x-coordinate shall
15be measured along a line drawn due east from a due north and south line running
16through the point which is the western extremity of this state, to the point to be
17located.
