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 this dilutes the voting strength of Black residents in state Supreme Court elections, in violation of the Voting Rights Act and the U.S. Constitution.

League of Women Voters Education Fund v. Trump
On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commission—an agency that Congress specifically established to be bipartisan and independent—to require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.
On behalf of leading voter registration organizations and advocacy organizations, the ACLU and co-counsel filed a lawsuit to block the Executive Order as an unconstitutional power grab.

Eternal Vigilance Action, Inc. v. Georgia
The ACLU and partner organizations intervened in this case to represent the rights of voters and voting-rights organizations in a case challenging a number of rules passed by the Georgia State Election Board. We challenged the rule requiring that the number of votes cast be hand counted at the polling place prior to the tabulation of votes. In a critical victory for Georgia voters, in June 2025, the Georgia Supreme Court upheld a lower court’s decision permanently blocking the rule requiring hand counting of ballots at polling places before tabulation — a process widely criticized for risking delays, ballot spoliation, and voter disenfranchisement.

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.

Montana Federation of Public Employees v. State of Montana
Representing Western Native Voice and four sovereign tribal nations in Montana, the American Civil Liberties Union, ACLU of Montana, and Native American Rights Fund (NARF) challenged the latest in a line of Montana laws that hinder Native American participation in the state’s electoral process — SB 490, which drastically limits access to Election Day voter registration (EDR) in Montana. These laws violate a number of provisions in the Montana Constitution: the right to vote, equal protection, and due process.

O'Bannon v. King
Virginia permanently disenfranchises all people with felony convictions unless the governor restores their rights. This lawsuit—brought by the ACLU of Virginia and co-counsel partners—argues that the policy violates the Readmissions Act of 1870, which bars Virginia from denying the vote based on convictions that didn’t exist at common law in 1870. The state tried to dismiss the case by invoking sovereign immunity, but the courts rejected that argument. Now, the case moves forward with the potential to restore voting rights to thousands of Virginians.

Republican National Committee v. Genser
Voters in Butler County, Pennsylvania made a mistake in voting their mail ballots in the April 2024 primary election, forgetting to use the required secrecy envelope. Because their mail ballots could not be counted, they went to the polls in Election Day and voted provisional ballots. The County later determined that it would not count their provisional ballots, and the voter’s appealed, arguing that Pennsylvania law requires that when an eligible voter attempts to vote by mail but the mail ballot is rendered void due to some defect like lacking a secrecy envelope, the eligible voter may cast a provisional ballot and have that ballot counted notwithstanding the failed attempt to vote by mail.

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.
