Plaintiffs challenging state district maps under Section 2 of the Voting Rights Act of 1965 must demonstrate that a state intentionally redistricted to diminish representation for minority voters. Decided April 29, 2026 (argued March 24, 2025). Opinion of the Court: Samuel Alito → go there Dissenting: Kagan. Applied: the Fourteenth Amendment → go there Applied: the Fifteenth Amendment → go there Topic: Voting and redistricting. Louisiana v. Callais, consolidated with Robinson v. Callais, 608 U.S. ___ (2026), is a landmark decision of the Supreme Court of the United States concerning racial gerrymandering and redistricting in the state of Louisiana following the 2020 United States census. After the Supreme Court's decision in Allen v. Milligan, the Louisiana legislature produced a new map under court orders, allocating two of the state's six districts as majority-minority districts using the state's 2020 census demographics and in compliance with Section 2 of the Voting Rights Act. The new maps were challenged as racially-gerrymandered and a constitutional violation of the Fourteenth and Fifteenth Amendments. In a 6–3 decision, the Court ruled along ideological lines that affirmed the federal district panel's judgement that the new redistricting map was an unconstitutional racial gerrymander under the Fifteenth Amendment.
