Gerrymandering
Allen v. Milligan
Whether Alabama’s congressional districts violate Section 2 of the Voting Rights Act because they discriminate against Black voters. We succeeded in winning a new map for 2024 elections which, for the first time, has two congressional district that provide Black voters a fair opportunity to elect candidates of their choosing despite multiple attempts by Alabama to stop us at the Supreme Court. Despite this win, Alabama is still defending its discriminatory map, and a trial was held in February 2025 to determine the map for the rest of the decade.
In May 2025, a federal court ruled that Alabama's 2023 congressional map both violates Section 2 of the Voting Rights Act and was enacted by the Alabama Legislature with racially discriminatory intent.

White v. Mississippi State Board of Elections
District lines used to elect Mississippi’s Supreme Court have gone unchanged for more than 35 years. We’re suing because the current lines crack the Mississippi Delta and dilute the voting strength of Black Mississippians in state Supreme Court elections, in violation of the Voting Rights Act.

Robinson v. Landry
Robinson challenged the congressional map that Louisiana enacted after the 2020 Census. ACLU and partners represented Plaintiffs the Louisiana State Conference of the NAACP, Power Coalition for Equity and Justice, and several impacted voters, and argued that the enacted plan violated Section 2 of the Voting Rights Act. In June 2022, the district court found Louisiana’s congressional map unlawfully denied Black voters a second district in which Black voters had an equal opportunity to elect their candidates of choice. After appeals, the legislature passed a new map containing two majority Black districts in January 2024.

Commonwealth v. Graham
State legislatures are responsible for creating state legislative and U.S. congressional districts. In 2019, the U.S. Supreme Court held in Rucho v. Common Cause that federal courts have no authority to review claims that states have sorted voters along partisan lines to favor one political party over others. However, challenges to partisan gerrymandering continue in many state courts, and this case involves one such constitutional challenge in Kentucky.
