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.

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.

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.
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.

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.

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.

Planned Parenthood Great Northwest, Hawai’i, Indiana, Kentucky v. Labrador
In April 2023, a group of health care providers and advocates sued to stop Idaho Attorney General Labrador from applying a legal opinion in which he claims that health care providers cannot refer patients out of state for abortion care under Idaho law. Under the opinion, any assistance from a health care provider — including offering information about other states’ abortion providers and abortion funds — could be a violation of Idaho’s abortion ban, threatening health care licenses or even criminal prosecution. This interpretation goes far beyond Idaho’s law and is an extreme attempt to prevent health care providers from giving information to patients and to prevent Idahoans from accessing legal health care in another state.

ACLU v. FBI - FOIA Case for FBI Records Related to Nondisclosure Agreements for Cell Site Simulators
In 2021, the ACLU submitted a FOIA request to the FBI to determine whether the FBI has continued to require state and local law enforcement agencies to enter into nondisclosure agreements before purchasing or using cell site simulators. After appealing and suing, the ACLU finally obtained responsive records confirming that the FBI has continued to impose nondisclosure agreements on law enforcement agencies seeking to use the FBI’s cell site simulators.

The Satanic Temple v. Saucon Valley School District
The American Civil Liberties Union (ACLU), the ACLU of Pennsylvania, and Dechert LLP filed a lawsuit in federal court against the Saucon Valley School District (SVSD) in March 2023 for violating the First Amendment by prohibiting the After School Satan Club (ASSC) from meeting in district facilities. Although school officials initially approved the club’s application — explaining in an email to parents that the district “cannot discriminate among groups wishing to use the SVSD facilities” — they quickly bowed to the ensuing public outcry. The case seeks to allow the ASSC to meet in district facilities.

Brown v. Lexington County, et al
This case is part of a nationwide fight against criminalization of poverty and, specifically, debtors' prisons. On June 1, 2017, the ACLU's Racial Justice Program, the ACLU of South Carolina, and Terrell Marshall Law Group PLLC filed a federal lawsuit challenging the illegal arrest and incarceration of indigent people in Lexington County, South Carolina, for failure to pay fines and fees, without determining willfulness or providing assistance to counsel. Those targeted by this long-standing practice could avoid jail only if they paid the entire amount of outstanding court fines and fees up front and in full. Indigent people who were unable to pay were incarcerated for weeks to months without ever seeing a judge, having a court hearing, or receiving help from a lawyer. The result was one of the most draconian debtors’ prisons uncovered by the ACLU since 2010.
