Supreme Court Hears Voting Rights Act Redistricting Challenge in Louisiana

What the Louisiana Fight Means for Section 2

The U.S. Supreme Court heard oral argument in Louisiana v. Callais, a case that asks whether a congressional map drawn to satisfy Section 2 of the Voting Rights Act can instead be struck down as an unconstitutional racial gerrymander. The argument exposed a tension between the Voting Rights Act and the Fourteenth Amendment that has unsettled redistricting law since the 1990s.

Louisiana has six U.S. House seats, and Black residents make up roughly one-third of the state's population. For years, the state used a map that gave Black voters an electoral opportunity in one of those six districts. After the Supreme Court's June 2023 ruling in Allen v. Milligan, a federal court concluded that the one-of-six arrangement likely diluted Black voting strength under Section 2.

In January 2024, Louisiana Governor Jeff Landry signed a new map with two majority-Black districts. One of those districts, the 6th, joins parts of Baton Rouge and Shreveport along the Red River corridor. Cleo Fields won that seat in 2024. A group of non-Black voters then sued, arguing that the district is an unconstitutional racial gerrymander rather than an appropriate remedy for proven vote dilution.

Who has the most at stake

The immediate stakes are Louisiana's district lines, but the ruling will reach any state that has defended a Section 2 redistricting plan in federal court. If the map is struck down, Louisiana would have to redraw its districts and candidates would face new geography, new constituents, new qualifying deadlines, and a compressed campaign calendar. If the map survives, states defending remedial majority-Black districts will have more clarity about how far they can go.

Black voters in Louisiana are among the most directly affected. Civil rights organizations that represent them describe the challenge as an attempt to narrow Section 2's reach at a moment when demographic change has made majority-minority districts more common and more contested. Election administrators are watching too. A redraw would force new precinct assignments, changed polling places, updated voter notices, and a new round of parish-level proofing for every affected district.

Beyond Louisiana, the case is being tracked by lawyers for state legislative staff, political party lawyers, nonprofit voting groups, and redistricting researchers. The court's answer will shape how mapmakers weigh racial data against partisan data when the two overlap, which they often do in the Deep South.

How Section 2 and the Fourteenth Amendment collide

Section 2 of the Voting Rights Act of 1965 prohibits any voting practice that denies or abridges the right to vote on account of race. In redistricting cases, courts use the test from Thornburg v. Gingles. The minority group must be large enough and compact enough to constitute a majority in one district. The group must be politically cohesive. White bloc voting must usually be sufficient to defeat the group's preferred candidate, a threshold that often turns on statistical analysis of local elections. When those conditions are met, a state usually must create a district that gives minority voters an equal opportunity to elect their preferred candidate.

The Department of Justice Voting Section maintains an overview of Section 2 of the Voting Rights Act, including how the Gingles factors are applied in redistricting cases.

Since Shaw v. Reno in 1993, the Supreme Court has also said that race cannot be the predominant factor in drawing district lines unless the state has a compelling reason and a narrowly tailored method. Compliance with Section 2 can be that compelling reason, but the state must show a strong basis in evidence that the law actually required the district. The Louisiana case sits at that exact intersection.

The challengers say the 6th District exists because the legislature sorted voters by race and ignored traditional districting values such as compactness and community boundaries. The state says the map was drawn because a federal court found a likely Section 2 violation, not because lawmakers preferred a racial outcome.

How the case reached the Supreme Court

• June 2023: The Supreme Court decides Allen v. Milligan and reaffirms that Section 2 requires Alabama to draw a second majority-Black district or an equivalent opportunity district.
• January 2024: Louisiana's Legislature passes a new congressional map in a special session, and Governor Jeff Landry signs it into law.
• April 2024: A federal district court blocks the new map as a racial gerrymander in the case then captioned Robinson v. Landry.
• May 2024: The Supreme Court grants an emergency stay, allowing Louisiana to use the challenged map for the 2024 election cycle.
• March 2025: The justices hear oral argument in Louisiana v. Callais and the consolidated case Robinson v. Callais.

The Supreme Court's decision to take the case was notable because the court does not have to resolve every redistricting dispute. By granting review, the justices signaled that they want to clarify the relationship between Section 2 and racial gerrymandering, not simply decide whether one Louisiana district is too irregular.

What the justices asked

During the argument, several conservative justices pressed Louisiana's counsel to explain how the 6th District's configuration was not predominantly race-based. They asked whether the state could point to political justifications or traditional districting interests that would have produced the same lines. Several liberal justices pointed to Louisiana's history of voting discrimination and the fact that the map was drawn in direct response to a court order enforcing Section 2.

A recurring question was how to distinguish racial purpose from partisan purpose in a state where Black voters overwhelmingly support one party and white voters overwhelmingly support another. Lawyers for the state and for the challengers gave different answers to that same question, and the answer may determine whether the court's middle justices can find a narrow ground on which to decide the case.

The argument also touched on remedies. If Section 2 plaintiffs win, what can a state draw to avoid a vote dilution violation without triggering a racial gerrymandering suit? Some justices appeared worried that a remedy would be impossible to administer if every majority-Black district drawn in response to Section 2 were subject to strict scrutiny.

What a ruling could change

A ruling against Louisiana would not eliminate Section 2, but it would make compliance riskier. A state would need to show that race did not predominate even when it drew a district specifically to satisfy a court finding of vote dilution. That could push states toward influence districts or coalition districts, which may be more difficult for plaintiffs to litigate under existing precedent.

A ruling for Louisiana would not make racial gerrymandering claims disappear. States would still need a strong evidentiary basis and a narrowly drawn remedy. But a victory for the state would confirm that a court order under Section 2 is a legitimate reason to use race in districting when the evidence satisfies the Gingles test.

The case is also a test of whether the Allen v. Milligan coalition holds. In that 5-4 decision, Chief Justice John Roberts and Justice Brett Kavanaugh joined the court's liberal justices to preserve Section 2's reach. Louisiana v. Callais asks whether that same coalition will accept the remedial maps that Section 2 sometimes demands.

Legal filings and the full argument are collected on SCOTUSblog's Louisiana v. Callais page. The court's eventual opinion will be published on the Supreme Court's own docket page, and the terms of that opinion will determine whether Louisiana's 6th District stands.

What to watch next

The court is expected to issue a decision before the current term ends. The first indication of how the justices are splitting will come from the opinion's assignment and, if there are separate writings, from the language of concurrences and dissents. A narrow ruling limited to Louisiana's particular map would leave unresolved many of the questions raised at argument, while a broad ruling could reset the relationship between the Voting Rights Act and the Constitution for a generation of redistricting cases.

For now, the 6th District remains in place. Cleo Fields holds the seat, voters are assigned under the challenged lines, and the 2026 election cycle is approaching with the legal status of the map unsettled. The next development is likely to be an opinion release, not a hearing, and it will arrive with little warning on a Thursday or Friday opinion list, the way the court now announces its most consequential work.
