The Supreme Court's 6-3 ruling in Louisiana v. Callais replaces the Voting Rights Act's effects-based test with an intent requirement, upending four decades of redistricting law.
The Supreme Court issued a 6-3 decision on April 29, 2026, striking down Louisiana's 2024 majority-Black congressional district map as an unconstitutional racial gerrymander and, in the same ruling, holding that plaintiffs bringing claims under Section 2 of the Voting Rights Act must now demonstrate intentional racial discrimination to prevail [1]. Justice Samuel Alito authored the majority opinion. The ruling discards the effects-based liability framework the Court established in *Thornburg v. Gingles* (1986), which had governed Section 2 litigation for four decades and permitted plaintiffs to prove a violation by showing that a challenged practice resulted in minority voters having less opportunity to participate in the political process [2].
*Louisiana v. Callais* arose from Louisiana's post-*Allen v. Milligan* redistricting cycle. After the Court's 2023 decision in *Allen* ordered Alabama to draw a second majority-Black district, Louisiana redrew its own congressional map to create a second majority-Black seat [2]. Challengers immediately sued, arguing the new map constituted an impermissible racial gerrymander. The case reached the Supreme Court on expedited review, with the justices simultaneously addressing both the racial-gerrymander claim against Louisiana's remedial map and the underlying standard of proof required to sustain a Section 2 cause of action.
The intentional-discrimination requirement represents a structural shift in voting rights law. Under *Gingles*, plaintiffs could establish a Section 2 violation through statistical and circumstantial evidence of discriminatory effect without proving a legislature acted with discriminatory purpose [2]. That effects test fueled decades of litigation that produced or preserved majority-minority districts across the South. Requiring proof of intent imposes a burden closer to what the Court demands under the Equal Protection Clause, a standard that civil rights organizations, including the Legal Defense Fund, have long characterized as nearly impossible to meet in redistricting cases [1]. Justice Sonia Sotomayor authored the principal dissent [1].
The political and legal fallout arrived immediately. Alabama Governor Kay Ivey publicly stated that Alabama would not initiate new redistricting proceedings in response to the ruling, a position that drew sharp partisan criticism within the state [1]. Redistricting advocates noted that states across the South, including Alabama, now possess increased latitude to draw maps that would previously have been vulnerable under the *Gingles* framework. Alabama Reps. Terri Sewell and Shomari Figures publicly opposed the ruling, while Alabama Attorney General Steve Marshall praised it [1]. Legal challenges already pending in multiple Southern states face reassessment under the new standard, and election law practitioners expect lower federal courts to begin applying the intent requirement to cases already in litigation.
