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.

Immigrants' Rights
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.

Racial Justice
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.

Woodruff v. Oliver
On December 5, 2024, the ACLU and the ACLU of Michigan filed an amicus brief in Woodruff v. Oliver, a wrongful arrest lawsuit in the United States District Court for the Eastern District of Michigan, arguing that the Detroit Police Department’s (DPD) reliance on flawed facial recognition technology (FRT) impermissibly tainted the investigation and failed to establish probable cause for the plaintiff’s arrest.

Comprehensive Health of Planned Parenthood Great Plains & Planned Parenthood Great Rivers v. Missouri
The ACLU, ACLU of Missouri, and Planned Parenthood Federation of America are representing Missouri’s two Planned Parenthood providers. Following the passage of Amendment 3, the Right to Reproductive Freedom Initiative, Comprehensive Health of Planned Parenthood Great Plains and Planned Parenthood Great Rivers, filed suit to restore abortion access in the state. The suit seeks to enjoin Missouri’s numerous abortion bans and countless burdensome, medically unnecessary restrictions on abortion that do not improve care or protect patient health. If the requested preliminary relief is granted, Planned Parenthood’s health centers would be able to begin providing abortion in Missouri once more — restoring access to this constitutionally protected health care.

Trabelsi v. Crawford, et al. – Lawsuit Challenging Unlawful Detention and Inhumane Treatment of Acquitted Man
Our client, Nizar Trabelsi, is in the United States against his will. The federal government brought him here from Belgium more than a decade ago and charged him with terrorism-related crimes. At trial, the government’s case failed: a federal jury found Mr. Trabelsi not guilty. But instead of allowing Mr. Trabelsi to return to Belgium after his acquittal, the United States placed him in highly restrictive immigration detention and began an ongoing effort to force him to Tunisia, where he was born and where he will very likely be tortured.
Mr. Trabelsi’s detention violates the Constitution, immigration law, and the extradition treaty between the United States and Belgium. Through this lawsuit, he seeks to return to Belgium, and he demands an immediate improvement of his detention conditions.

Billard v. Charlotte Catholic High School
Lonnie Billard worked at Charlotte Catholic High School for more than a decade – both as full-time drama and as a long-term substitute teacher – and has won numerous teaching awards, including teacher of the year. In October 2014, Lonnie wrote a Facebook post announcing that he and his long-time partner were getting married. Later that year, the school told Lonnie he could no longer work as a substitute teacher because his engagement and marriage to another man was contrary to the religious principles of the Catholic Church.

Powers v. McDonough
Every night, thousands of veterans sleep without shelter on the streets of Los Angeles. Meanwhile, the Department of Veterans Affairs owns hundreds of acres of land in prime West Los Angeles—land directly adjacent to a VA medical facility that was once earmarked to house veterans, but today is instead home to private school sports fields and an oil well.
In November 2022, a group of unhoused veterans and a non-profit organization filed suit alleging that the Department of Veterans Affairs (“VA”) failed to provide adequate housing and health care to veterans with severe disabilities in Los Angeles. These failures have significantly undermined veterans’ abilities to access the benefits they are entitled to by law, leaving many stranded on the streets after serving our country. The veterans sued the VA under the Rehabilitation Act, a federal statute that prohibits federal agencies from discriminating against people with disabilities. As a remedy, the plaintiffs seek the construction of significant units of permanent supportive housing on the
The VA argued that a provision of the Veterans’ Judicial Review Act (“VJRA”)— a federal statute that prohibits federal district courts from second-guessing VA’s individualized benefits determinations—bars federal district courts from hearing the veterans’ Rehabilitation Act claims. Should the court accept this position, it would deprive veterans of a meaningful opportunity to have their rights under the Rehabilitation Act and other generally applicable nondiscrimination statutes enforced.
