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.

CAIR-Foundation, Inc and CAIR Florida, Inc. v. DeSantis et al.
The ACLU, the ACLU of Florida, the Southern Poverty Law Center, and their partners represent CAIR and CAIR-Florida in two federal lawsuits challenging Governor DeSantis’s unconstitutional and baseless designation of the nonprofits as “terrorist.” The lawsuits allege violations of CAIR and CAIR-Florida’s rights under the First Amendment and the due process clause of the Fourteenth Amendment.

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.

Jensen v. Thornell
UPDATE: On July 17, 2026, U.S. District Judge Roslyn O. Silver issued an order formally appointing a receiver to assume control and management of health care provided to more than 25,000 people incarcerated in Arizona Department of Corrections, Rehabilitation, and Reentry (ADCRR) prisons, in a long-running lawsuit against the state prison system brought by the Prison Law Office, the American Civil Liberties Union (ACLU), ACLU of Arizona, and Disability Rights Arizona.

Voting Rights
Coalition for Open Democracy v. Scanlan
This lawsuit challenges HB 1569, a new law that will make New Hampshire the only state to require every person to produce documentary proof of citizenship when they register to vote for both state and federal elections. It also challenges HB 1569’s elimination a preexisting protection for voters—namely, an affidavit option that allowed voters who faced surprise challenges to their eligibility at the polls to swear to their qualifications and cast a ballot. Accordingly, HB 1569 violates the First and Fourteenth Amendments of the U.S. Constitution by placing substantial burdens on New Hampshirites at all stages of the voting process, and will arbitrarily disenfranchise hundreds, if not thousands of qualified voters.

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.

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.

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.

Reproductive Freedom
Preterm-Cleveland v. David Yost
On September 2, 2022, the American Civil Liberties Union, the ACLU of Ohio, Planned Parenthood Federation of America, and the law firm WilmerHale filed a lawsuit in the Hamilton County Court of Common Pleas bringing a state constitutional challenge against SB 23, a law banning abortion starting at approximately six weeks of pregnancy. This lawsuit came more than two months after the draconian bill took effect on June 24, 2022 for the first time since it was passed in 2019, causing an immediate, devastating crisis across the state. Due to the ongoing irreparable harm to Ohioans, the reproductive rights organizations withdrew the lawsuit they initially filed in the state Supreme Court in late June and asked the lower court to grant immediate relief blocking the ban.

Citizens Project v. City of Colorado Springs
Colorado Springs’s unusually-timed elections suppress voter turnout—disproportionately, among the City’s Black and Hispanic population. This federal court lawsuit challenges the City’s election timing for violating our clients’ right to vote free from denial of abridgment on account of race under the Voting Rights Act of 1965.

Smart Justice
Just City, Inc. v. Bonner
Shelby County (Memphis), Tennessee, historically set cash bail in criminal cases without stopping to ask whether people would be able to bail out. This practice unnecessarily detained people who could not afford to pay for release, but who would otherwise return to court and live peacefully in their communities. The ACLU Criminal Law Reform Project negotiated a historic settlement with Shelby County to end this practice.
In retaliation, the Tennessee legislature passed HB 1719, which prohibits judges from considering an arrestee’s ability to pay when setting bail. This law is unprecedented. Our lawsuit seeks to enjoin Shelby County officials from enforcing it.

LGBTQ Rights
Loe v. Texas
In the spring of 2023, Texas became the largest state in the country to ban gender-affirming care for transgender youth after Governor Greg Abbott signed SB 14. In July 2023, a lawsuit was filed on behalf of five Texas families, three medical professionals, and two organizations representing hundreds of families and health professionals across the state. The five Texas families challenging this law come from diverse backgrounds across the state with transgender children and teenagers. The bill’s passage alone resulted in families splitting up or planning to leave Texas to continue treatment for their children. The families are suing pseudonymously to protect themselves and their children, who are transgender Texans between the ages of 9 and 16.
