Supreme Court Strikes Down Louisiana's Congressional Map in Louisiana v. Callais

On April 29, 2026, the Supreme Court decided Louisiana v. Callais, one of the most closely watched voting cases in years — and the ruling reshapes how states can draw congressional maps.

What happened

Louisiana drew a new congressional map (S.B. 8) that created a second majority-Black district. The state did this partly in response to earlier litigation under the Voting Rights Act, which can require districts where a minority group has been denied an equal chance to elect candidates. A group of voters challenged the new map, arguing that lawmakers let race predominate — which the Equal Protection Clause of the Fourteenth Amendment limits.

What the Court held

A divided Court agreed with the challengers. It concluded that race predominated in the drawing of S.B. 8 and that the map could not survive strict scrutiny, so it affirmed the decision striking the map down.

What it means for you

The case sits on a genuine fault line. Section 2 of the Voting Rights Act sometimes requires states to consider race to avoid diluting minority votes, while the Equal Protection Clause restricts maps where race is the dominant factor. After Callais, that tension is sharper: states face a harder path to draw majority-minority districts, and commentators across the spectrum read the decision as weakening Section 2’s practical force.

For everyday voters, the immediate effect shows up in district lines — which can change who represents you and how competitive your district is. To understand the law underneath the case, read our breakdowns of the Voting Rights Act and the Fourteenth Amendment.
