Voting Rights
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.

Voting Rights
League of Women Voters of Massachusetts v. Trump
On March 31, 2026, President Trump issued a sweeping Executive Order titled "Ensuring Citizen Verification and Integrity in Federal Elections," seeking once again to seize control of election administration from Congress and the states. The Order directs federal agencies to compile lists of U.S. citizens and transmit them to states before every election, directs the U.S. Postal Service -- an independent agency established by Congress -- to create a list of "approved" mail voters, and instructs USPS to refuse to deliver ballots from voters not on that federally created list. If implemented, the Order would threaten the ability of millions of eligible citizens to cast their ballots, particularly military members, overseas citizens, the elderly, recently naturalized citizens, and voters with disabilities who rely on mail voting.

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.

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.
Missouri
Apr 2026
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.
Tennessee Supreme Court
Apr 2026
Capital Punishment
Tony Von Carruthers v. State of Tennessee
Tennessee plans to execute Tony Carruthers on May 21 even though they refuse to run a simple fingerprint comparison and DNA testing that could prove what Tony has been arguing for 30 years - that he is innocent of this crime and that Tennessee convicted and sentenced the wrong man to death.
U.S. Supreme Court

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.
Mississippi
Dec 2025
Voting Rights
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.

Voting Rights
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.

Nguyen v. State
This case concerns the constitutionality of a highly intrusive law enforcement practice: the use of geofence warrants. Geofence warrants compel tech companies like Google to provide to law enforcement location data from every cell phone likely to have been within a certain area during a given time window. Then, law enforcement officers decide for themselves which users to focus on, and demand additional location information—and eventually identifying information—for the users they select. Geofence warrants raise grave constitutional concerns, including that (1) they authorize dragnet searches that sweep up the private data of many people without probable cause to believe that all or any of them were involved in any crime, and (2) they allow law enforcement officers to decide which users to focus on for additional data collection without judicial oversight. This case therefore has significant implications for Texans’ ability to secure their digital privacy and property against unjustified government intrusion.

Montana Federation of Public Employees v. 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.

Withrow v. United States et al
LeAnne Withrow of Springfield, Illinois is a lead military and family readiness specialist and civilian employee for the Illinois National Guard. Previously, she served as a staff sergeant for the National Guard and is the recipient of multiple commendations and awards, including the Illinois National Guard Abraham Lincoln Medal of Freedom.
Following a January 20, 2025 executive order signed by President Trump, officials with the U.S. Office of Personnel Management, the U.S. Department of Defense, and the federal National Guard Bureau issued notices to all employees requiring use of designated restrooms strictly based upon their “biological sex,” as inaccurately defined in the executive order. Soon after, Withrow was told by supervisors within her chain of command that she could not use restrooms designated for women.
On May 5, Ms. Withrow filed a class action complaint to the Army National Guard Bureau Equal Opportunity Office (NGB-EO), and later to the U.S. Equal Employment Opportunity Commission (EEOC), challenging the federal order, but both the NGB-EO and EEOC failed to resolve the matter.
In November 2025, Withrow filed a class action lawsuit alleging that the executive order and implementation actions violate Title VII of the Civil Rights Act of 1964, which prohibits sex discrimination in employment, and that the order and implementation violate the federal Administrative Procedure Act. The complaint was filed on behalf of Ms. Withrow by the American Civil Liberties Union, the ACLU of D.C., the ACLU of Illinois, and Democracy Forward.
“No one should have to choose between their career in service and their own dignity,” said Withrow. “I bring respect and honor to the work I do to support military families, and I hope the court will restore dignity to transgender people like me who serve this country every day.”
