Congressional Redistricting and the Voting Rights Act: A Legal Overview

Summary
The Constitution requires a count of the U.S. population every 10 years. Based on the census, the
number of seats in the House of Representatives is reapportioned among the states. Thus, at least
every 10 years, in response to changes in the number of Representatives apportioned to it or to
shifts in its population, each state is required to draw new boundaries for its congressional
districts. Although each state has its own process for redistricting, congressional districts must
conform to a number of constitutional and federal statutory standards, including the Voting Rights
Act (VRA) of 1965, as amended.
The VRA was enacted under Congress’s authority to enforce the 15th Amendment, which provides
that the right of citizens to vote shall not be denied or abridged on account of race, color, or
previous servitude. In particular, Section 2 of the VRA prohibits the use of any voting
qualification or practice—including the drawing of congressional redistricting plans—that results
in the denial or abridgement of the right to vote based on race, color, or membership in a
language minority. The statute further provides that a violation is established if, based on the
totality of circumstances, it is shown that political processes are not equally open to members of a
racial or language minority group in that its members have less opportunity than other members
of the electorate to participate and to elect representatives of choice. In decisions including
Thornburg v. Gingles and Bartlett v. Strickland, the Supreme Court further interpreted the
requirements of Section 2.
Section 5 of the VRA requires certain covered jurisdictions—based on a formula set forth in
Section 4(b)—to “preclear” their congressional redistricting plans with either the Department of
Justice or the U.S. District Court for the District of Columbia before implementation. In order to
be granted preclearance, the covered jurisdiction has the burden of proving that the proposed
voting change neither has the purpose, nor will it have the effect, of denying or abridging the right
to vote on account of race or color, or membership in a language minority group. On February 27,
2013, the U.S. Supreme Court will hear a case challenging the constitutionality of the VRA’s
preclearance requirement. In Shelby County, Alabama v. Holder, the Court will consider whether
Congress’s decision in 2006 to reauthorize Section 5 of the VRA under the preexisting coverage
formula contained in Section 4(b) exceeded its authority under the 14th and 15th Amendments,
thereby violating the 10th Amendment and Article IV of the U.S. Constitution. The Court will
likely issue its decision by the end of June.
In the 113th Congress, legislation has been introduced that would establish certain standards and
requirements for congressional redistricting, including identical bills H.R. 223 and H.R. 278, the
“John Tanner Fairness and Independence in Redistricting Act,” and H.R. 337, the “Redistricting
Transparency Act of 2013.”

Congressional Redistricting and the Voting Rights Act: A Legal Overview

he Constitution requires a count of the U.S. population every 10 years.1 Based on the
census, the number of seats in the House of Representatives is reapportioned among the
Tstates.2 Thus, at least every 10 years, in response to changes in the number of
Representatives apportioned to it or to shifts in its population, each state is required to
draw new boundaries for its congressional districts. Although each state has its own process for
redistricting, congressional districts must conform to a number of constitutional and federal
statutory standards,3 including the Voting Rights Act (VRA) of 1965, as amended.4
The VRA was enacted under Congress’s authority to enforce the 15th Amendment, which provides
that the right of citizens to vote shall not be denied or abridged on account of race, color, or
previous servitude.5 In a series of cases and evolving jurisprudence, the U.S. Supreme Court has
interpreted how the VRA applies in the context of congressional redistricting. These decisions
inform how congressional district lines are drawn in the future, and whether legal challenges to
redistricting will be successful.
This report provides a legal overview of two key provisions of the VRA affecting congressional
redistricting—Sections 2 and 5—and selected accompanying Supreme Court case law. It also
provides a summary of selected legislation in the 112th Congress that would establish additional
requirements and standards for congressional redistricting.
For further discussion of the process of congressional redistricting and the apportionment of
congressional seats, see CRS Report R41357, The U.S. House of Representatives Apportionment
Formula in Theory and Practice, by Royce Crocker.

Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law
direct.”).
2 U.S. CONST. amend. XIV, §2, cl. 1 (“Representatives shall be apportioned among the several States according to
their respective numbers ...”).
3 While beyond the scope of this report, congressional districts are also subject to the one-person, one-vote equality
standard. See Wesberry v. Sanders, 376 U.S. 1, 7-8, 18 (1964) (interpreting article I, section 2, clause 1 of the U.S.
Constitution that Representatives be chosen “by the People of the several States” and be “apportioned among the
several States ... according to their respective Numbers,” to require that “as nearly as is practicable, one man’s vote in a
congressional election is to be worth as much as another’s”); Karcher v. Dagett, 462 U.S. 725, 740 (1983) (holding that
absolute population equality is the standard unless a deviation is necessary to achieve “some legitimate state objective,”
such as “consistently applied legislative policies,” including, for example, “making districts more compact, respecting
municipal boundaries, preserving the cores of prior districts, and avoiding contests between incumbents.”). In addition,
congressional districts might theoretically be subject to claims of partisan political gerrymandering, although the
standard that a court could use, to ascertain such a determination and grant relief, remains unresolved. See LULAC v.
Perry, 548 U.S. 399 (2006) (plurality opinion); CRS Report RS22479, Congressional Redistricting: A Legal Analysis of

United States or by any State on account of race, color, or previous condition of servitude.”). Since its ratification in
1870, however, the use of various election procedures by certain states diluted the impact of votes cast by African
Americans or prevented voting entirely. As case-by-case enforcement under the Civil Rights Act proved to be
protracted and ineffective, Congress enacted the Voting Rights Act of 1965. See H. REP. NO. 89-439, at 1, 11-12, 15-

such as poll taxes, literacy tests, and vouching requirements).

Congressional Redistricting and the Voting Rights Act: A Legal Overview

Section 2 of the Voting Rights Act
Congressional district boundaries in every state are required to comply with Section 2 of the
VRA. Section 2 provides a right of action for private citizens or the government to challenge
discriminatory voting practices or procedures, including minority vote dilution, the diminishing
or weakening of minority voting power.
Specifically, Section 2 prohibits any voting qualification or practice—including the drawing of
congressional redistricting plans—applied or imposed by any state or political subdivision that
results in the denial or abridgement of the right to vote based on race, color, or membership in a
language minority.6 The statute further provides that a violation is established if:
based on the totality of circumstances, it is shown that the political processes leading to
nomination or election in the State or political subdivision are not equally open to
participation by [members of a racial or language minority group] in that its members have
less opportunity than other members of the electorate to participate in the political processes
and to elect representatives of their choice.7
“Majority-Minority” District Requirement
Under certain circumstances, the creation of one or more “majority-minority” districts may be
required in a congressional redistricting plan. A majority-minority district is one in which a racial
or language minority group comprises a voting majority. The creation of such districts can avoid
racial vote dilution by preventing the submergence of minority voters into the majority, which can
deny minority voters the opportunity to elect a candidate of their choice. In the landmark decision
Thornburg v. Gingles,8 the Supreme Court established a three-prong test that plaintiffs claiming
vote dilution under Section 2 must prove:
First, the minority group must be able to demonstrate that it is sufficiently large and
geographically compact to constitute a majority in a single-member district....
Second, the minority group must be able to show that it is politically cohesive....
Third, the minority must be able to demonstrate that the white majority votes sufficiently as a
bloc to enable it—in the absence of special circumstances, such as the minority candidate
running unopposed—usually to defeat the minority’s preferred candidate.9
The Court also discussed how, under Section 2, a violation is established if based on the “totality
of the circumstances” and “as a result of the challenged practice or structure plaintiffs do not have
an equal opportunity to participate in the political processes and to elect candidates of their

9 Id. at 50-51 (citation omitted). The three requirements set forth in Thornburg v. Gingles for a Section 2 claim apply to
single-member districts as well as to multi-member districts. See Growe v. Emison, 507 U.S. 25, 40-41 (1993) (“It
would be peculiar to conclude that a vote-dilution challenge to the (more dangerous) multimember district requires a
higher threshold showing than a vote-fragmentation challenge to a single-member district.”) Id. at 40.

choice.”10 In order to facilitate determination of the totality of the circumstances the Court listed
the following factors, which originated in the legislative history accompanying enactment of
Section 2:
1. the extent of any history of official discrimination in the state or political subdivision that
touched the right of the members of the minority group to register, to vote, or otherwise to
participate in the democratic process;
2. the extent to which voting in the elections of the state or political subdivisions is racially
polarized;
3. the extent to which the state or political subdivision has used unusually large election
districts, majority vote requirements, anti-single shot provisions, or other voting practices or
procedures that may enhance the opportunity for discrimination against the minority group;
4. if there is a candidate slating process, whether the members of the minority group have
been denied access to that process;
5. the extent to which members of the minority group in the state or political subdivision
bear the effects of discrimination in such areas as education, employment and health, which
hinder their ability to participate effectively in the political process;
6. whether political campaigns have been characterized by overt or subtle racial appeals;
7. the extent to which members of the minority group have been elected to public office in
the jurisdiction.11
Requirement that Minority Group Constitute More Than 50% of
Voting Population in Single-Member District
In 2009 the Supreme Court further interpreted the three-prong test that it had established in
Gingles. In Bartlett v. Strickland,12 the Court ruled that the first prong of the Gingles test—
requiring geographical compactness sufficient to constitute a majority in a district—can only be
satisfied if the minority group constitutes more than 50% of the voting population if it were in a
single-member district.13 In Bartlett, it had been argued that Section 2 requires drawing district
lines in such a manner to allow minority voters to join with other voters to elect the minority
group’s preferred candidate, even where the minority group in a given district comprises less than
50% of the voting age population.
Rejecting that argument, the Court found that Section 2 does not grant special protection to
minority groups that need to form political coalitions in order to elect candidates of their choice.

that in some cases have had probative value as part of plaintiffs’ evidence to establish a violation are: whether there is a
significant lack of responsiveness on the part of elected officials to the particularized needs of the members of the
minority group [and] whether the policy underlying the state or political subdivision’s use of such voting qualification,
prerequisite to voting, or standard, practice or procedure is tenuous.”) Id.

Congressional Redistricting and the Voting Rights Act: A Legal Overview

According to the Court, to mandate recognition of Section 2 claims where the ability of a
minority group to elect candidates of choice relies upon “crossover” majority voters would result
in “serious tension” with the third prong of the Gingles test, which requires that the minority be
able to demonstrate that the majority votes sufficiently as a bloc to enable it usually to defeat
minority-preferred candidates.14
Constitutional Limits Under 14th Amendment
Equal Protection Clause
Congressional redistricting plans must also conform with standards of equal protection under the
14th Amendment to the U.S. Constitution.15 According to the Supreme Court, if race is the
predominant factor in the drawing of district lines, above other traditional redistricting
considerations—including compactness, contiguity, and respect for political subdivision lines—
then a “strict scrutiny” standard of review is applied. In this context, strict scrutiny review
requires that a court determine that the state has a compelling governmental interest in creating a
majority-minority district, and that the redistricting plan is narrowly tailored to further that
compelling interest. Case law in this area demonstrates a tension between compliance with the
VRA and conformance with standards of equal protection.16
In its 2001 decision, Easley v. Cromartie (Cromartie II),17 the Supreme Court upheld the
constitutionality of the long-disputed 12th Congressional District of North Carolina against the
argument that the 47% black district was an unconstitutional racial gerrymander. In this case,
North Carolina and a group of African American voters had appealed a lower court decision
holding that the district, as redrawn by the legislature in 1997 in an attempt to cure an earlier
violation, was still unconstitutional. The Court determined that the basic question presented in
Cromartie II was whether the legislature drew the district boundaries “because of race rather than
because of political behavior (coupled with traditional, nonracial redistricting considerations).”18
In applying its earlier precedents, the Court determined that the party attacking the legislature’s
plan had the burden of proving that racial considerations are “dominant and controlling.”19
Overturning the lower court ruling, the Supreme Court held that the attacking party did not
successfully demonstrate that race—instead of politics—predominantly accounted for the way the
plan was drawn.

Congressional Redistricting and the Voting Rights Act: A Legal Overview

Section 5 of the Voting Rights Act
Section 5 of the VRA was enacted to eliminate possible future denials or abridgements of the
right to vote in those states or political subdivisions that are considered “covered” jurisdictions.
Covered jurisdictions are determined under a formula set out in Section 4(b) of the VRA.20
Currently, nine states are covered: Alabama, Alaska, Arizona, Georgia, Louisiana, Mississippi,
South Carolina, Texas, and Virginia. In addition, portions of seven other states are covered:
California, Florida, Michigan, New Hampshire, New York, North Carolina, and South Dakota.21
Before implementing a change to “any voting qualification or prerequisite to voting, or standard,
practice, or procedure with respect to voting”22—which includes congressional redistricting
plans—Section 5 requires a covered jurisdiction to obtain “preclearance” approval for the
proposed change. Covered jurisdictions can seek preclearance from either the U.S. Attorney
General or the U.S. District Court for the District of Columbia.23 In order to be granted
preclearance, the covered jurisdiction has the burden of proving that the proposed voting change
“neither has the purpose nor will have the effect of denying or abridging the right to vote on
account of race or color,” or membership in a language minority group.”24 Moreover, as amended
in 2006, the statute expressly provides that its purpose is “to protect the ability of such citizens to
elect their preferred candidates of choice.”25
Unlike certain other provisions of the VRA, the preclearance requirements of the act are
scheduled to expire. In 2006, Congress amended the act to extend the applicability of the
preclearance requirements until 2031.26
“Effect” Test
According to the Supreme Court, a redistricting plan will be determined to have a discriminatory
effect—and accordingly, preclearance will be denied—if it will lead to retrogression in minority
voting strength.27 In Beer v. U.S.,28 the Court found that a plan that increased the number of
African American city council majority districts from one to two enhanced the voting strength of

Rosa Parks, Coretta Scott King, Cesar E. Chavez, Barbara C. Jordan, William C. Velasquez, and Dr. Hector P. Garcia
Voting Rights Act Reauthorization and Amendments of 2006 [effective July 27, 2006].”).
27 For redistricting plans submitted to the Attorney General for administrative review, Department of Justice regulations
provide that a change affecting voting is considered to have a discriminatory effect if it will lead to retrogression in the
position of members of a racial or language minority group, that is, members of such groups will be “worse off than
they had been before the change.” In order to determine retrogressive effect, a proposed redistricting plan will be
compared to a “benchmark” plan. The “benchmark” plan against which a proposed plan is compared is the most recent
legally enforceable redistricting plan in force or effect at the time of the submission. 28 C.F.R. §51.54(b),(c) (2011);

racial minorities and therefore, could not have the effect of diluting voting rights due to race
under Section 5.29 According to the Court, Section 5 is intended to prevent changes in voting
procedures that would lead to a diminishing in the ability of racial minorities to exercise their
right to vote effectively.30 Clarifying the retrogression standard, in City of Lockhart v. U.S.31 the
Court approved an electoral change that, although it did not improve minority voting strength, did
not result in retrogression. Invoking its decision in Beer, the Court found that if a new
redistricting plan does not diminish the voting strength of African Americans, it is entitled to
preclearance under Section 5.32 Likewise, in Reno v. Bossier Parish School Board (Bossier Parish
I),33 the Supreme Court affirmed the retrogression standard for Section 5 preclearance when it
refused to replace it with a standard of racial vote dilution, which is the standard contained in
Section 2 of the VRA. According to the Court, “a violation of § 2 is not grounds in and of itself
for denying preclearance under § 5.”34
When it amended Section 5 in 2006, Congress added a provision expressly stating that its purpose
is “to protect the ability of such citizens to elect their preferred candidates of choice.”35 According
to the legislative history, this amendment was made to address a 2003 Supreme Court decision,
Georgia v. Ashcroft.36 In Georgia, a Senate Report noted, the Court determined that preclearance
would be permitted under Section 5 in cases where majority-minority districts, in which
minorities had the ability to elect a candidate of choice, were replaced with “influence districts,”
in which minorities could impact an election, but not necessarily play a decisive role. Calling the
standard established by the Court in Georgia, “ambiguous,” the Senate Report indicated that the
intent of the amendment was to restore Section 5 to the “workable” standard that the Court
espoused in Beer.37 In Beer, the Court inquired whether, under the proposed redistricting plan, the
ability of minority groups to elect candidates of choice is diminished.38
“Purpose” Test
Congress also amended Section 5 of the VRA in 2006 with the intent of expanding the definition
of “purpose.” Specifically, the law was changed to provide that “[t]he term ‘purpose’ ... shall
include any discriminatory purpose.”39 The legislative history indicates that this amendment was
made in response to the 2000 decision in Reno v. Bossier Parish School Board (Bossier Parish
II)40 where the Supreme Court found that Ҥ 5 does not prohibit preclearance of a redistricting

plan enacted with a discriminatory but nonretrogressive purpose.”41 A Senate report
accompanying the legislation to amend Section 5 observed that under the standard articulated in
Bossier Parish II, preclearance could be granted to redistricting plans enacted with a
discriminatory purpose, so long as the purpose was only to perpetuate unconstitutional
circumstances, and not to make them worse.42
According to the Senate report,
The Supreme Court’s decision in Bossier Parish II has created a strange loophole in the law:
it is possible that the Justice Department or federal court could be required to approve an
unconstitutional voting practice ... [and the] federal government should not be giving its seal
of approval to practices that violate the Constitution. Under this amendment, which forbids
voting changes motivated by ‘any discriminatory purpose,’ it will not do so.43
Release from Coverage
Section 4(a) of the VRA sets forth a procedure whereby covered states or political subdivisions,
as defined in Section 4(b), may be released from coverage under the Section 5 preclearance
provision. Specifically, a covered jurisdiction must demonstrate, in an action for declaratory
judgment in the U.S. District Court for the District of Columbia, that during the previous ten
years and during the pendency of the action:
(A) “no ... test or device has been used within such State or political subdivision for the
purpose or with the effect of denying or abridging the right to vote on account of race or
color”;
(B) “no final judgment of any court of the United States, other than the denial of declaratory
judgment under this section, has determined that denials or abridgements of the rights to vote
on account of race or color have occurred anywhere in the territory of such State or political
subdivision”;
(C) “no Federal examiners or observers under this Act have been assigned to such State or
political subdivision”;
(D) “such State or political subdivision and all governmental units within its territory have
complied with section 5 of this Act, including compliance with the requirement that no
change covered by section 5 has been enforced without preclearance under section 5, and
have repealed all changes covered by section 5 to which the Attorney General has
successfully objected or as to which the United States District Court for the District of
Columbia has denied a declaratory judgment”;
(E) “the Attorney General has not interposed any objection (that has not been overturned by
a final judgment of a court) and no declaratory judgment has been denied under section 5,
with respect to any submission by or on behalf of the plaintiff or any governmental unit
within its territory under section 5, and no such submissions or declaratory judgment actions
are pending; and

Congressional Redistricting and the Voting Rights Act: A Legal Overview

(F) “such State or political subdivision and all governmental units within its territory—(i)
have eliminated voting procedures and methods of election which inhibit or dilute equal
access to the electoral process; (ii) have engaged in constructive efforts to eliminate
intimidation and harassment of persons exercising rights protected under this Act; and (iii)
have engaged in other constructive efforts, such as expanded opportunity for convenient
registration and voting for every person of voting age and the appointment of minority
persons as election officials throughout the jurisdiction and at all stages of the election and
registration process.”44
Constitutionality
In November 2012, the U.S. Supreme Court agreed to hear a case challenging the
constitutionality of the VRA’s preclearance requirement. In Shelby County, Alabama v. Holder,45
the Court will consider whether Congress’s decision in 2006 to reauthorize Section 5 under the
preexisting coverage formula contained in Section 4(b) exceeded its authority under the 14th and
15th Amendments, thereby violating the 10th Amendment and Article IV of the U.S. Constitution.
The Court will hear oral argument in this case on February 27, 2013, and will likely issue its
decision by the end of June.
This case arises from an appeal by Shelby County, Alabama to a May 2012 D.C. Court of Appeals
decision in which the court, by a vote of 2 to 1, upheld the constitutionality of Section 5.46
According to the court, Congress’s decision in 2006 to extend Section 5 until 2031 was
reasonable and deserving of judicial deference. Specifically, the court found that the preclearance
requirements while “severe,” remain “congruent and proportional” to the problem of voting
discrimination in covered jurisdictions.47 In contrast, the dissent criticized the coverage formula
as outdated with insufficient justification for distinguishing among those jurisdictions that are
covered and those that are not.48
In its petition for writ of certiorari, Shelby County argued that when Congress extended the law in
2006, it failed to justify the preclearance requirement by documenting patterns of racial voting
discrimination in violation of the 15th Amendment, and that the coverage formula no longer only
applies to jurisdictions in which there is intentional racial voting discrimination. Accordingly,
Shelby County argued that the law fails the congruence and proportionality standard of review
and is unconstitutional.49
This litigation appears against a historical background of cases in which the Supreme Court has
repeatedly upheld the constitutionality of Section 5. Following the enactment of the VRA in 1965,
in South Carolina v. Katzenbach,50 the Supreme Court upheld Section 5’s constitutionality.

Congressional Redistricting and the Voting Rights Act: A Legal Overview

law to be “a valid means for carrying out the commands of the Fifteenth Amendment.”51
Following the 1975 reauthorization of Section 5, in City of Rome v. United States,52 the Court
reaffirmed its holding in Katzenbach, and likewise upheld its constitutionality. Similarly, in Lopez
v. Monterey County,53 the Court upheld the constitutionality of Section 5 after its 1982
reauthorization finding that although “the Voting Rights Act, by its nature, intrudes on state
sovereignty,” nonetheless, “[t]he Fifteenth Amendment permits this intrusion.”54
In more recent cases, however, the Supreme Court has expressed concerns with the
constitutionality of Section 5. In the wake of the 2006 reauthorization and amendments to Section
5, a municipal utility district in Texas filed suit asking to be released from Section 5 preclearance
requirements. In the alternative, the utility district challenged the law’s constitutionality, arguing
that Congress exceeded its enforcement power under the 15th Amendment. While not answering
the question of Section 5’s constitutionality, in the 2009 decision of Northwest Austin Municipal
Utility District Number One (NAMUDNO) v. Holder,55 the Court cautioned that the VRA’s
preclearance regime and coverage formula “raise serious constitutional questions.”56 Although
acknowledging that some of the conditions it had relied upon in upholding Section 5 in
Katzenbach and City of Rome are better, the Court pointed out that these improvements may be
insufficient, and therefore, preclearance requirements may still be necessary. Nevertheless, the
Court pointed out that the law “imposes current burdens and must be justified by current needs.”57
In NAMUDNO, the Court avoided the constitutional question by deciding that the utility district
was eligible to be released from coverage.58 In an early 2012 decision, the Supreme Court
reiterated its observation from NAMUDNO that Section 5’s intrusion on state sovereignty “raises
serious constitutional questions.”59
Congressional Redistricting Legislation
The following provides an overview of selected legislation that would establish additional
requirements and standards for congressional redistricting.

55 129 S.Ct. 2504 (2009).
56 Id. at 2513.
57 Id. at 2512. (“The evil that § 5 is meant to address may no longer be concentrated in the jurisdictions singled out for
preclearance. The statute’s coverage formula is based on data that is now more than 35 years old, and there is
considerable evidence that it fails to account for current political conditions.”) Id.
