Missouri v. U.S. Department of Commerce
A coalition of civil rights and immigrant-rights organizations has moved to intervene as defendants in a lawsuit that threatens to dismantle the Constitution’s long-standing requirement that the decennial census count all people living in the United States. Missouri asks the court to exclude undocumented immigrants and people living in the country on temporary visas from the census count used to determine congressional representation—an unprecedented move that would upend more than two centuries of constitutional practice.

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.

FOIA Case Seeking the Trump Administration’s Legal Justification for Deadly Boat Strikes
The Department of Justice’s Office of Legal Counsel (“OLC”) authored a legal opinion that reportedly claims to justify the Trump administration’s illegal lethal strikes on civilians in boats in the Caribbean Sea and eastern Pacific Ocean. Media reports indicate that, in addition to claiming that the strikes are lawful acts in an alleged “armed conflict” with unspecified drug cartels, the OLC opinion also purports to immunize personnel who authorized or took part in the strikes from future criminal prosecution. Because the public deserves to know how our government is justifying these illegal strikes, and why they think the people who carried them out should not be held accountable, the ACLU is seeking immediate release of the OLC legal opinion and related documents pursuant to the Freedom of Information Act.

Barbara v. Donald J. Trump
President Trump is attempting to undermine the promise of birthright citizenship to children born on U.S. soil. But the ACLU and partners are fighting to protect the rights of citizens that are plainly stated in the Constitution, federal statute, and reaffirmed by the Supreme Court for more than a century. We’re arguing against the Trump administration in the Supreme Court and are confident we will win.

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.

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.

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.

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.

White v. Shwedo
In the latest front in the nationwide fight against the criminalization of poverty, on October 31, 2019, the American Civil Liberties Union, ACLU of South Carolina, Terrell Marshall Law Group PLLC, Southern Poverty Law Center, and South Carolina Appleseed Legal Justice Center filed a federal lawsuit challenging South Carolina’s policy of automatically suspending the driver’s licenses of people with unpaid traffic tickets. The South Carolina Department of Motor Vehicles does not ensure that people who cannot pay will not lose their licenses in violation of the Fourteenth Amendment’s promise of due process and equal protection under the law. South Carolina’s wealth-based license suspensions impact more than 190,000 people, funneling those who are unable to pay, particularly poor people of color, deep into cycles of poverty, job loss, traffic violations, and entanglement with the legal system.

Nashville Community Bail Fund v. Gentry
In Nashville, local officials keep money posted as bail to pay fines and fees. This happens even when the person whose bond was posted shows up to their required court dates. Under a local court rule and policies from the criminal clerk, pretrial release is conditioned on future payment, which leverages pretrial freedom to make money for the government.

J.W. v. Paley
It is critical that the Fifth Circuit Court of Appeals clarify that the Fourth Amendment applies to the use of force against schoolchildren. J.W. v. Paley involves Fourteenth and Fourth Amendment claims stemming from a police officer tasing a high school student with disabilities who was attempting to exit the school building to calm down following an incident with another student. The district court dismissed the Fourteenth Amendment claim based on precedent, but allowed the Fourth Amendment claim to proceed, denying qualified immunity to the officer. The Fifth Circuit, however, reversed the lower court’s decision regarding the Fourth Amendment claim, ultimately leaving schoolchildren without any constitutional protection from excessive force by law enforcement in the Fifth Circuit.
