Louisiana v. Callais — The Majority Opinion

608 U.S. ___ (2026) · Alito, J. (6–3) · joined by Roberts, C.J., and Thomas, Gorsuch, Kavanaugh, and Barrett, JJ. · Thomas, J., concurring · Kagan, J., dissenting (with Sotomayor and Jackson, JJ.)

The Court holds that because the Voting Rights Act, §2, as properly construed, did not require Louisiana to create an additional majority-black district, no compelling interest justified the State's race-based map (SB8) — so SB8 is an unconstitutional racial gerrymander. Five diagrams, of five different kinds, walk through how the majority gets there: the chronology, the cast, the analytic test, the rebuilt doctrinal framework, and the rationale for rebuilding it.

Held: Compliance with a properly construed §2 can be a compelling interest — but §2 imposes liability only on a strong inference of intentional racial discrimination, and here it did not require the new district. SB8 fails strict scrutiny. 732 F. Supp. 3d 574, affirmed and remanded.

         : SB8 is an unconstitutional racial gerrymander, affirmed and remanded

The bind the State was in

Louisiana was whipsawed between two courts. One federal court (Middle District, Robinson) said its first map probably violated §2 because it lacked a second majority-black district. When the State complied by drawing that district in SB8, a second court (Western District, Callais) said the new map was an unconstitutional racial gerrymander. The Supreme Court resolves the squeeze by holding the first court was wrong: §2 never required the district, so the State should never have drawn it on racial lines.

2 · The cast and the two-case tangle — relationship map

Relationship map: two suits, two district courts, two maps, two constitutional theories.

    SCOTUS              ||--o{ SB8           : "unconstitutional, Sec 2 did not require it"

Why this matters

The Robinson plaintiffs (VRA §2) and the Callais plaintiffs (Equal Protection) are different people pulling in opposite directions, which is what makes the case hard to follow. The majority's move is to make the §2 case (left side) the dispositive question: because the Robinson plaintiffs never actually proved a §2 violation, the State's racial response in SB8 (right side) had no legal justification.

The pivot

The majority concedes the point §2 defenders wanted — compliance with §2 can be a compelling interest — and then defeats the map on the next question: §2, correctly read, requires a strong inference of intentional racial discrimination, and it never actually required this district. The constitutional-avoidance engine in Part I does the work: because the Fifteenth Amendment reaches only purposeful discrimination, §2 cannot be read to impose liability on mere disparate impact (citing Reno v. Bossier Parish, City of Boerne). So §2 liability, and therefore any §2-based compelling interest, attaches only on evidence of intentional discrimination.

What changed

Precondition 1. An illustrative map now proves only that the State could draw the district — to prove §2 was violated, the plaintiff's map must use no race as a criterion and must meet all the State's legitimate goals, including its stated political goals.
Preconditions 2 & 3. Racial-bloc-voting evidence must now control for party — the plaintiff has to show bloc voting that partisan affiliation cannot explain.
Totality. The inquiry refocuses on present-day intentional discrimination; old history and "effects of societal discrimination" get much less weight (Shaw v. Hunt).

The throughline

Each development pushes the same direction: race and party have become entangled, partisan gerrymandering claims have nowhere else to go after Rucho, and modern mapping makes "greater racial balance" easy to demonstrate. The majority uses these to justify a framework that screens out partisan disputes dressed up as racial ones — and to distinguish Allen v. Milligan, which (it says) never reached these questions or the Fourteenth Amendment at all.
