The Supreme Court’s 29 April ruling in Louisiana v. Callais (2026) declared Louisiana’s congressional maps with two majority Black districts to be unconstitutional. The Court’s decision guts the 1965 Voting Rights Act (VRA). Section 2 of the VRA prohibited discriminatory voting practices and additional amendments allowed for the creation of majority-minority congressional districts like the two majority Black districts in Louisiana. With the 6-3 ruling, the Court’s six Republican appointees ruled that Louisiana’s second majority Black district is an unconstitutional racial gerrymander. The effect of this ruling is that Louisiana and other states no longer must ensure that minority communities are represented.
Under the new Section 2 guidelines, majority-minority districts can only be created in extremely limited circumstances, in incredibly slim numbers, and to correct existing racial disparities present within the challenged map itself. The district must be demonstrated to be not motivated by partisanship in any way, as that would make it fall under a nonjusticiable “political” question.
States are also no longer encouraged to create additional majority-minority districts if a second is possible; instead, in evaluating the validity of a map, the Court weighs whether the absence of a second district is truly discriminatory.
On April 29, 2026, the U.S. Supreme Court ruled 6–3 in Louisiana v. Callais (consolidated with Robinson v. Callais) that Louisiana’s congressional map containing a second majority-Black district (SB8) was an unconstitutional racial gerrymander under the Fifteenth Amendment. [1, 2]
Key Details of the Ruling
The Decision & Holding: Justice Samuel Alito wrote the 6–3 majority opinion (joined by Roberts, Thomas, Gorsuch, Kavanaugh, and Barrett; Kagan, Sotomayor, and Jackson dissented), ruling that Section 2 of the Voting Rights Act did not require or justify the race-based creation of Louisiana's second majority-Black district (SB8). [1, 2]
Shift on Section 2: The ruling shifts the standard for Section 2 claims toward an intent-based requirement, finding a violation only when a state intentionally disadvantages minority voters because of their race. [1, 2]
Background: Stemming from a lower-court order following Allen v. Milligan to add a majority-Black district, the resulting map (SB8) was subsequently challenged by non-Black voters as an unconstitutional racial gerrymander. [1, 2, 3]
Aftermath: Analysts warn that the decision significantly curtails Section 2 redistricting challenges nationwide, sparking calls among lawmakers for federal legislative action to restore previous VRA protections. [1, 2, 3]
