Overview of 2020 Redistricting

After lawmakers overrode Gov. John Bel Edwards’ March 2022 veto and locked in a six-seat plan with just one majority-Black district, Black voters sued in Robinson v. Ardoin. Chief Judge Shelly Dick enjoined the map in June 2022, but the U.S. Supreme Court paused that order while it decided Allen v. Milligan. Post-Milligan, in which the U.S. Supreme Court revived Section 2 jurisprudence, the Fifth Circuit gave Baton Rouge until Jan. 15 2024, to fix the violation. In a January special session, the new Republican governor, Jeff Landry, signed SB 8 (Act 2), adding a second majority-Black district, but white voters promptly filed Callais v. Landry. A three-judge panel struck down Act 2 as a racial gerrymander in April 2024, only for the Supreme Court to keep the map in place for the 2024 elections.

The Supreme Court heard reargument in October 2025 and, on April 29, 2026, issued a 6-3 ruling authored by Justice Alito affirming that Act 2 was an unconstitutional racial gerrymander and, significantly, rewriting the Gingles evidentiary framework in ways that make future Section 2 vote-dilution claims far harder to bring. The day after the ruling, Gov. Landry suspended the scheduled May 16 congressional primaries to give the legislature time to act. The legislature then passed SB 121, which Landry signed as Act 2 of the 2026 Regular Session, reverting largely to the 2022 five-Republican, one-majority-Black configuration, eliminating the second majority-Black district won by Rep. Cleo Fields in 2024. A three-judge federal panel has scheduled a hearing for June 17–18, 2026, to assess whether the new map complies with the Callais ruling. Congressional primaries are now scheduled as a jungle primary on November 3, 2026, with any runoffs on December 12.

Louisiana's state legislative lines face a parallel challenge. The Senate (SB 1) and House (HB 14) plans became law without the governor’s signature on Mar. 9 2022. Black voters soon filed Nairne v. Ardoin, but proceedings were stayed until Milligan was decided. After a November-December 2023 bench trial, a district court ruled on Feb. 8 2024 that both the Senate and House maps violate Section 2 and ordered the legislature to redraw them; the state appealed, and the Fifth Circuit heard argument on Jan. 7 2025, staying any remedial deadline in the meantime.
