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 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

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.

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.

Poe et al. v. Harris-Madden et al.
The ACLU, NYCLU, Family Justice Law Center, Brooklyn Defender Services, Center for Family Representation, NYU School of Law Family Defense Clinic, and Sullivan & Cromwell have filed a federal class action lawsuit on behalf of three New York parents challenging unconstitutional delays in the appeals process for reports on the Statewide Central Register of Child Abuse and Maltreatment (SCR). Parents who challenge their placement on the registry often wait months—sometimes more than a year—for a final decision. While they wait, they can be shut out of jobs in childcare, education, healthcare, and other fields involving children, and barred from adopting or fostering. Low-income parents, parents of color, and disabled parents are disproportionately policed by the family regulation system—also known as the child welfare system—and more likely to end up on the registry. This lawsuit seeks to ensure that parents have a way to clear their names in a timely manner.

Moe v. Yost
Two transgender adolescents and their families are challenging Ohio’s House Bill 68, a law passed in January 2024 that prohibits gender-affirming medical care that is widely accepted to treat gender dysphoria, helping alleviate the distress of gender dysphoria and significantly improving patients’ mental health and well-being. Such treatment is supported by leading medical experts and all major U.S. medical organizations, including the American Medical Association, the American Psychiatric Association, and the American Academy of Pediatrics.
