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.

Nairne v. Landry poses a challenge under Section 2 of the Voting Rights Act of 1965 to Louisiana’s House and Senate legislative maps on behalf of plaintiff Black voters and Black voters across the state.

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.

Whether the congressional map Louisiana adopted to cure a Voting Rights Act violation in Robinson v. Ardoin is itself unlawful as a gerrymander.

The American Civil Liberties Union, the ACLU of Ohio, Planned Parenthood Federation of America, the law firm WilmerHale, and Fanon Rucker of the Cochran Law Firm, on behalf of Planned Parenthood Southwest Ohio Region, Planned Parenthood of Greater Ohio, Preterm-Cleveland, Women’s Med Group Professional Corporation, Dr. Sharon Liner, and Julia Quinn, MSN, BSN, amended a complaint in an existing lawsuit against a ban on telehealth medication abortion services to bring new claims under the Ohio Reproductive Freedom Amendment, including additional challenges to other laws in Ohio that restrict access to medication abortion in the state.

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.

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.

This case involves a state constitutional challenge to South Carolina’s 2022 congressional redistricting plan, which legislators admit was drawn to entrench a 6-1 Republican majority in the state’s federal delegation. Plaintiff the League of Women Voters of South Carolina has asked the state’s Supreme Court to conclude that the congressional map is an unlawful partisan gerrymander that violates the state constitution.

Idaho and Moyle, et al. v. United States was appealed to the U.S. Supreme Court by Idaho politicians seeking to disregard a federal statute — the Emergency Medical Treatment and Labor Act (EMTALA) — and put doctors in jail for providing pregnant patients necessary emergency medical care. The Supreme Court heard oral arguments on this case on April 24, 2024. The Court’s ultimate decision will impact access to this essential care across the country.
