Louisiana v. Callais Revisions: 5/04/26
The Supreme Court ruled that Louisiana's congressional map adding a second majority-Black district was an unconstitutional racial gerrymander — and in so doing, fundamentally rewrote how the Voting Rights Act applies to redistricting.
The decision makes it far harder for minority voters to challenge redistricting maps in court, requiring evidence pointing toward intentional racial discrimination rather than merely discriminatory effects, and leaves many existing majority-minority congressional districts across the country at legal risk.
“Section 2 of the Voting Rights Act of 1965, 52 U. S. C. §10301 et seq., was designed to enforce the Constitution— not collide with it.”
The majority's opening sentence frames the central tension between the Voting Rights Act and the Constitution's bar on race-based government action.
How it got here: A three-judge federal district court in Louisiana held that SB8 violated the Equal Protection Clause; Louisiana and intervenors from the prior redistricting suit appealed directly to the Supreme Court.
The Case in Depth
What happened
Louisiana drew a new congressional map after the 2020 census with only one majority-Black district, even though about one-third of the state's population is Black. A federal judge found the map likely violated the Voting Rights Act and ordered the state to add a second majority-Black district. Louisiana complied by drawing SB8, a map that created District 6 — a 250-mile corridor connecting Black communities in Baton Rouge, Lafayette, and Shreveport. A separate group of voters then sued, arguing SB8 was itself an unconstitutional racial gerrymander.
The question before the Court
After a federal court told Louisiana its congressional map likely violated the Voting Rights Act for lacking a second majority-Black district, the State drew a new map adding one. Did that race-based map violate the Constitution?
The Court's answer
Yes — Louisiana's map was an unconstitutional racial gerrymander. The State drew District 6 specifically to achieve a Black voter majority, which triggered strict scrutiny — the most demanding constitutional test, requiring both a compelling reason for using race and a closely tailored use of race. Louisiana argued that a court order to comply with the Voting Rights Act gave it the necessary compelling interest.
The Court agreed that Voting Rights Act compliance can in theory be a compelling interest, but only if Section 2 of the Act actually required the race-based action. The Court reinterpreted Section 2 to impose liability only when evidence points toward intentional racial discrimination — not merely because a map produces unequal racial outcomes from otherwise permissible map-drawing choices. Under that reading, the prior court order directing Louisiana to draw a second majority-Black district was based on a misapplication of Section 2, which never actually required such a district. With no valid legal obligation driving the racial design, Louisiana had no compelling interest to justify SB8.

Why it matters
States that have drawn majority-minority congressional districts under the Voting Rights Act now face far less legal pressure to maintain them. A state wishing to crack a minority community can assert partisan goals — protecting incumbents of one party, for example — and Section 2 will likely offer no protection. Minority communities in the South and elsewhere that hold representation through majority-minority districts could lose that representation in future redistricting cycles.
What changes now
The case is sent back to the district court for proceedings consistent with the Supreme Court's ruling. Louisiana's SB8 map is invalidated and the State will need to redraw its congressional districts. More broadly, states that have drawn majority-minority districts in response to Section 2 claims now face significantly less legal pressure to maintain them, because future challengers must show evidence pointing toward intentional racial discrimination — a far harder standard than the prior effects-based test.
What this does not decide
The Court says it has not overruled Allen v. Milligan and is not declaring all majority-minority districts unconstitutional. Section 2 can still support a redistricting challenge where circumstances create a strong inference of intentional racial discrimination. The majority also insists it is only "updating," not abandoning, the Gingles framework — a claim the dissent sharply disputes.
Concurrences and dissents
How the Justices voted
Majority (6). Justice Alito (author), joined by Justice Roberts, Justice Thomas, Justice Gorsuch, Justice Kavanaugh, and Justice Barrett.
Dissent (3). Justice Kagan (author), joined by Justice Sotomayor and Justice Jackson.
Concurrence — Justice Thomas
Justice Thomas joined the Court's full opinion but wrote separately to argue the majority doesn't go far enough. In his view — which he has held for more than thirty years — Section 2 of the Voting Rights Act doesn't apply to redistricting at all. The statute, he argues, bars only rules governing access to the ballot or vote counting, not boundary-drawing. Under his approach, no Section 2 challenge to any redistricting plan could ever succeed.
Dissent — Justice Kagan
Justice Kagan argued that the majority effectively revives the intent requirement Congress explicitly rejected when it amended Section 2 in 1982. By requiring plaintiffs to show evidence pointing toward intentional racial discrimination, and demanding that alternative maps satisfy all of a state's partisan political goals, the majority makes vote-dilution claims nearly impossible to win. She called the decision the final step in the Court's 'demolition' of the Voting Rights Act and argued that Congress — not the Court — has the authority to decide when the law is no longer needed.

How the Court got there
The legal reasoning, step by step
- Because Louisiana openly used race to design District 6 — engineering a Black voting-age majority — strict scrutiny applied automatically. Strict scrutiny is the most demanding constitutional test: the government must have a very strong ('compelling') reason for using race and must use race only as much as absolutely necessary.
- The Court identified only two recognized compelling interests that can justify race-based government action: avoiding imminent prison safety emergencies, and fixing specific, identified past civil-rights violations. It then asked whether Voting Rights Act compliance should be added as a third compelling interest — and answered yes, but only if Section 2 of the Act actually required the race-based conduct.
- To determine what Section 2 demands, the Court analyzed its text. Section 2 bars maps that give minority voters 'less opportunity than other members of the electorate to elect representatives of their choice.' The Court read this to mean minority voters are entitled only to whatever opportunity a map drawn under the State's permissible, race-neutral criteria would provide — and that Section 2 imposes liability only when circumstances give rise to a strong inference the State intentionally drew lines to disadvantage minority voters because of their race.
- The Court updated the 40-year-old Gingles framework — the checklist courts have used to evaluate Section 2 vote-dilution claims — to align with this interpretation. The updates require: (a) alternative maps that plaintiffs submit cannot use race and must satisfy all of the State's legitimate goals, including partisan ones; (b) evidence of racially polarized voting must disentangle race from party affiliation; and (c) the overall 'totality of circumstances' inquiry must focus on present-day intentional racial discrimination, not historical patterns.
- Applying the updated framework to Louisiana: the earlier dilution plaintiffs whose lawsuit prompted SB8 failed at every step. Their alternative maps didn't protect the Republican incumbents the State sought to shield — one representative would have been placed in a district with more than twice as many registered Democrats as Republicans, effectively ensuring her defeat. Their racial-polarization evidence didn't control for partisan preferences. And their totality-of-circumstances showing relied on the State's historical record of discrimination rather than evidence of current intentional bias.
- Because Section 2, properly understood, never required Louisiana to draw a second majority-minority district, the State had no compelling interest for using race in SB8. Without a compelling interest, the race-based map could not survive strict scrutiny and was an unconstitutional racial gerrymander violating the Fourteenth Amendment's Equal Protection Clause.
