Voting Rights
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.

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

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.
Missouri

Voting Rights
Wise v. Missouri
In unprecedented fashion, the State of Missouri has redrawn the district lines used for electing members of Congress for a second time this decade. These new district lines are gerrymandered and will harm political representation for all Missourians, particularly Black residents in Kansas City, who have been divided along racial lines.

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.
Mississippi

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.
Louisiana

Nairne v. Landry
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.

Idaho and Moyle, et al. v. United States
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.

Heimel v. Gregg
The ACLU and partners intervened in a lawsuit that sought to illegally disenfranchise hundreds of Oconee County voters on the eve of the November 5 election. The Oconee lawsuit is just one in a wave of similar attempts by election vigilantes across the state to indiscriminately purge voters from the voter rolls in violation of the law.

Quinn v. Raffensperger
The ACLU, along with several partner organizations, have sought to intervene in this case to represent the rights of voters and voting-rights organizations in a case that asks a federal court to compel the state to conduct list maintenance and move voters to the inactive list on the eve of a presidential election. The relief that the private plaintiffs seek is presumptively unlawful because this list maintenance activity would happen within 90 days of a federal election, in violation of the National Voter Registration Act (“NVRA”).

Immigrants' Rights
Detention and Deportation Infrastructure FOIA Cases
Every year, ICE and other federal agencies spend billions of taxpayer dollars on a system to detain and deport immigrants. The people detained in this system face persistent medical neglect, abuse, and other violations. President Trump has threatened to dramatically expand this system, which will multiply the harms it causes. We’ve sued to obtain information about how this system operates so that we are better prepared to defend immigrants whose rights are under attack.
