Thornburg v. Gingles

Legislative history Section 2 of the Voting Rights Act of 1965 prohibits any jurisdiction from implementing a "voting qualification or prerequisite to voting, or standard, practice, or procedure ... in a manner which results in a denial or abridgement of the right ... to vote on account of race," color, or language minority status. The Supreme Court has allowed private plaintiffs to sue to enforce this prohibition. In City of Mobile v. Bolden (1980), the Supreme Court held that as originally enacted in 1965, Section 2 simply restated the Fifteenth Amendment and thus prohibited only those voting laws that were intentionally enacted or maintained for a discriminatory purpose. Congress responded by passing an amendment to the Voting Rights Act which President Ronald Reagan signed into law on June 29, 1982. Congress's amended Section 2 to create a "results" test, which prohibits any voting law that has a discriminatory effect irrespective of whether the law was intentionally enacted or maintained for a discriminatory purpose. The 1982 amendments provided that the results test does not guarantee protected minorities a right to proportional representation. When determining whether a jurisdiction's election law violates this general prohibition courts relied on factors enumerated in the Senate Judiciary Committee report associated with the 1982 amendments ("Senate Factors"), including: • The history of official discrimination in the jurisdiction that affects the right to vote; • The degree to which voting in the jurisdiction is racially polarized; • The extent of the jurisdiction's use of majority vote requirements, unusually large electoral districts, prohibitions on bullet voting, and other devices that tend to enhance the opportunity for voting discrimination; • Whether minority candidates are denied access to the jurisdiction's candidate slating processes, if any; • The extent to which the jurisdiction's minorities are discriminated against in socioeconomic areas, such as education, employment, and health; • Whether overt or subtle racial appeals in campaigns exist; • The extent to which minority candidates have won elections; • The degree that elected officials are unresponsive to the concerns of the minority group; and • Whether the policy justification for the challenged law is tenuous. The report indicates not all or a majority of these factors need to exist for an electoral device to result in discrimination, and it also indicates that this list is not exhaustive, allowing courts to consider additional evidence at their discretion. Section 2 prohibits two types of discrimination: "vote denial", in which a person is denied the opportunity to cast a ballot or to have their vote properly counted, and "vote dilution", in which the strength or effectiveness of a person's vote is diminished. Most Section 2 litigation has concerned vote dilution, especially claims that a jurisdiction's redistricting plan or use of at-large/multimember elections prevents minority voters from casting sufficient votes to elect their preferred candidates. Redistricting plans can be gerrymandered to dilute votes cast by minorities by "packing" high numbers of minority voters into a small number of districts or "cracking" minority groups by placing small numbers of minority voters into a large number of districts. Procedural history In July 1981 the North Carolina General Assembly enacted a redistricting plan in response to the 1980 United States census. In September 1981 plaintiffs sued North Carolina Attorney General Rufus L. Edmisten, alleging their votes would be submerged by multimember districts in violation of Section 2 of the Voting Rights Act. In January 1984 a special three-judge district court in the United States District Court for the Eastern District of North Carolina made up of Circuit Judge James Dickson Phillips, Chief District Judge William Earl Britt, and Senior District Judge Franklin Taylor Dupree Jr. agreed, finding that all the challenged districts violated Section 2 of the Voting Rights Act, and enjoined holding any elections under the General Assembly's redistricting plan. Chambers was supported by co-counsels, Lani Guinier, and Leslie Winner. ==Opinion of the Court==

On June 30, 1986, the last day of the term, the Supreme Court announced its decision, alongside Davis v. Bandemer and Bowers v. Hardwick. The Supreme Court unanimously affirmed that there were Section 2 violations in all of the statehouse districts except the Durham County, North Carolina multimember district, which a majority reversed. In an opinion by Justice William J. Brennan joined partially by Justices Byron White, Thurgood Marshall, Harry Blackmun, and John Paul Stevens the Court used the term "vote dilution through submergence" to describe claims that a jurisdiction's use of an at-large/multimember election system or gerrymandered redistricting plan diluted minority votes, and it established a legal framework for assessing such claims under Section 2. Under the Gingles test, plaintiffs must show the existence of three preconditions: • The racial or language minority group "sufficiently large and geographically compact to constitute a majority in a single-member district"; • The minority group is "politically cohesive" (meaning its members tend to vote similarly); and • The "majority votes sufficiently as a bloc to enable it ... usually to defeat the minority's preferred candidate." The first precondition is known as the "compactness" requirement and concerns whether a majority-minority district can be created. The second and third preconditions are collectively known as the "racially polarized voting" or "racial bloc voting" requirement, and they concern whether the voting patterns of the different racial groups are different from each other. If a plaintiff proves these preconditions exist, then the plaintiff must additionally show, using the remaining Senate Factors and other evidence, that under the "totality of the circumstances", the jurisdiction's redistricting plan or use of at-large or multimember elections diminishes the ability of the minority group to elect candidates of its choice. According to the plurality, race is the determinant, not a mere corollary, of voter behavior. For Justice White the race of the candidates also mattered; it would not be racially polarized if white voters elected a black candidate not supported by black voters. Without Justice White's fifth vote Justice Brennan's section on the relevant evidence only carried the authority of a plurality opinion. Concurrence in judgment Justice Sandra Day O'Connor, joined by Chief Justice Warren E. Burger, Justice Lewis F. Powell, Jr., and Justice William Rehnquist concurred in the judgment only. Justice O'Connor, a former Arizona statehouse legislator, began by noting that Senator Bob Dole, "the architect of the compromise", had insisted the 1982 amendment explicitly disclaim any right to racially proportional representation. Nevertheless, Justice O'Connor sees the majority opinion as attempting to create a right to "usual, roughly proportional representation". Justice O'Connor next agrees with Justice White that the plurality was wrong to insist the only relevant evidence is the race of the voters. She writes that the law does not permit "an arbitrary rule against consideration of all evidence considering voting preferences". Concurrence in part and dissent in part Justice Stevens, joined by Justices Marshall and Blackmun, joined the Court in affirming the three judge district court but dissented from reversing the judgment regarding the Durham County multimember district. Justice Stevens wrote that although Durham County had elected a black candidate in every election since 1972, the multimember district still violates the Voting Rights Act considering "the political realities of the State". Furthermore, Justice Stevens felt reversing without a remand was "mystifying" and "also extremely unfair." ==Subsequent developments==

Subsequent litigation further defined the contours of "vote dilution through submergence" claims. In Bartlett v. Strickland (2009), the Supreme Court held that the first Gingles precondition can be satisfied only if a district can be drawn in which the minority group comprises a majority of voting-age citizens. This means that plaintiffs cannot succeed on a submergence claim in jurisdictions where the size of the minority group, despite not being large enough to comprise a majority in a district, is large enough for its members to elect their preferred candidates with the help of "crossover" votes from some members of the majority group. In contrast, the Supreme Court has not addressed whether different protected minority groups can be aggregated to satisfy the Gingles preconditions as a coalition, and lower courts have split on the issue. The Supreme Court provided additional guidance on the "totality of the circumstances" test in Johnson v. De Grandy (1994). The opinion also distinguished the proportionality of majority-minority districts, which allows minorities to have a proportional opportunity to elect their candidates of choice, from the proportionality of election results, which Section 2 explicitly does not guarantee to minorities. Since Gingles, lower courts have split on the issue. Statisticians have observed that the Court's approach is invalidated by the ecological fallacy. Social scientists have found that federal judges vary widely when applying the Gingles preconditions. In Louisiana v. Callais (2026), the Supreme Court ruled that a minority district created in a redrawn map for Louisiana to match the state's demographics was an illegal racial gerrymander. The opinion described four major developments that had taken place since Gingles that put additional requirements to judicate Section 2 claims, making Section 2 challenges more difficult. ==See also==
