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.

State Board of Election Commissioners v. Mississippi State Conference of the NAACP
Mississippi has a growing Black population, which is already the largest Black population percentage of any state in the country. Yet. Black Mississippians continue to be significantly under-represented in the state legislature, as Mississippi’s latest districting maps fail to reflect the reality of the state’s changing demographics. During the 2022 redistricting process, the Mississippi legislature refused to create any new districts where Black voters have a chance to elect their preferred representative. The current district lines therefore dilute the voting power of Black Mississippians and continue to deprive them of political representation that is responsive to their needs and concerns, including severe disparities in education and healthcare.

Turtle Mountain Band of Chippewa Indians v. Howe (Amicus)
In Arkansas State Conference NAACP v. Arkansas Board of Apportionment, the 8th Circuit became the first federal appeals court to rule that private plaintiffs cannot enforce Section 2 of the Voting Rights Act. In doing so, the court left open the question whether private plaintiffs could enforce Section 2 through an alternative civil rights statute, 42 U.S.C. § 1983. In this case, a divided panel on the 8th Circuit has held that plaintiffs may not use Section 1983, either. If the holding stands, Section 2 of the VRA will be functionally out of reach for voters across the 8th Circuit in Arkansas, Iowa, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota. On behalf of the NAACP Arkansas State Conference and the Arkansas Public Policy Panel, the ACLU and ACLU of Arkansas has filed a brief supporting the plaintiffs' request that the full Eighth Circuit rehear and correct this decision.

League of Women Voters of Greeley, Weld County v. Board of County Commissioners of Weld County (Amicus)
When drawing its new maps, the Weld County Board of County Commissioners violated Colorado law imposing specific requirements meant to guarantee that county commission districts are drawn transparently and fairly, such that voters are empowered to elect responsive and accountable commissioners. A Colorado district court granted summary judgment to voter plaintiffs who challenged the maps, but the Board appealed the decision, arguing in part that voters lacked standing and a right of action to challenge the unlawful districts.

New York Communities for Change v. Nassau County
Voters of color in Nassau County, N.Y., are no strangers to having to organize to ensure their votes count. But in 2023, the county’s Legislature took vote dilution to new heights. In places like Elmont, Freeport, Inwood, Lakeview, South Valley Stream, New Hyde Park, and Uniondale, the Legislature “cracked and packed” communities of color with the effect of squashing their growing electoral power. But the landmark John R. Lewis Voting Rights Act of New York (NYVRA), enacted in 2022, and the New York Municipal Home Rule Law prohibit New York State and localities from diluting the voting strength and political influence of Black, Latino, and Asian residents.

Utah State Legislature v. League of Women Voters (Amicus)
This case involves a state constitutional challenge to the Utah Legislature’s 2021 redistricting plan, which was drawn to entrench the majority political party’s power and to discriminate against Utahns whose political expression aligns with an opposition political party. The ACLU and the ACLU of Utah filed an amicus brief in support of the challenge in the Utah Supreme Court, explaining why the redistricting map violates Utahns’ free-expression rights and why courts have the authority to block the map as unconstitutional.
