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.

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.

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.

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.

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.

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.

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
Oasis Family Birthing Center et. al. v. Alabama Department of Public Health
A group of midwives and doctors filed a lawsuit in state court challenging actions by the Alabama Department of Public Health (ADPH), which imposed a de facto ban on freestanding birth centers throughout Alabama. Birth centers provide midwifery care to low-risk pregnant patients, a model of care that is proven to be safe and beneficial to patients. Despite that, ADPH took actions that forced one center to abruptly shut down in 2023 despite a perfect safety record, and then passed onerous regulations that would require birth centers to meet hospital-like standards, preventing birth centers from operating in the state. After hearing oral argument in late September 2023, the Circuit Court of Montgomery County granted our request for a Preliminary Injunction on September 30, 2023, preventing ADPH from refusing to timely license freestanding birth centers that comply with nationally-recognized safety standards for birth centers while litigation continues.
In May 2025, the Fifteenth Judicial Circuit Court issued judgment in Plaintiffs’ favor on Plaintiffs’ threshold claim that freestanding birth centers are not “hospitals” under Alabama law and, therefore, the Alabama Department of Public Health (ADPH) has no authority to require them to be licensed as such.
However, on appeal in January 2026, the Alabama Court of Civil Appeals reversed the lower court's decision, and in May 2026, the Alabama Supreme Court declined the Plaintiffs’ request for further review, leaving the Civil Appeals Court’s decision in place.
The case now returns to the Circuit Court of Montgomery County where Plaintiffs will continue litigating other claims arguing that, even if ADPH has authority to require licenses for birth centers, the specific licensing rules ADPH adopted for freestanding birth centers unlawfully burden Alabamians’ access to birth center care.

Immigrants' Rights
Barco Mercado v. Mullin
An individual detained by Immigration and Customs Enforcement (ICE) sued the Trump administration over lack of access to legal counsel and unsafe conditions at 26 Federal Plaza, a federal building in New York where more than 100 people have been confined, sometimes for weeks, to a temporary holding facility operated by ICE. The holding facility is only meant to temporarily hold people who are immigrants for a matter of hours as they are processed before release or transported to a longer-term detention facility. It has no beds, showers, or adequate medical support. However, as ICE has increased its arrests of immigrants, it has packed people into the holding cells at 26 Federal Plaza, where they are detained for extended periods of time, often for a week or more. Detained individuals have estimated that ICE has packed between 70 to 90 people into a room of approximately 215 square feet.

ACLU et al. v. U.S. Department of Health and Human Services et al.
The American Civil Liberties Union (ACLU), the National Center for Youth Law (NCYL), and the New York Civil Liberties Union filed a lawsuit to demand transparency from the Trump administration regarding its treatment of pregnant unaccompanied immigrant youth in federal immigration custody. The lawsuit seeks to enforce the ACLU and NCYL’s February 2025 Freedom of Information Act (FOIA) request for records and correspondence from the Office of Refugee Resettlement (ORR), which oversees the care and custody of unaccompanied immigrant youth until they are placed with a sponsor, usually a family member in the United States. The release of this information is important to monitor whether the Trump administration is ensuring that these marginalized young people have access to the full range of pregnancy-related care while in government custody, as is required by law.
