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.

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.

Zyst v. Miller
Following the Oregon Department of Corrections’ unconstitutional treatment of a transgender prisoner, a habeas court ordered her removal from segregated housing, an individualized gender-affirming care assessment, a psychiatric evaluation, and identification of an appropriate cellmate. However, the Oregon Court of Appeals reversed the psychiatric-evaluation and cellmate orders, finding them “too attenuated” to qualify as habeas relief. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Oregon, joined an amicus brief by the law firm Sugerman Dahab arguing that habeas courts have broad discretion to remedy violations and resulting harms. The brief explains that the Court of Appeals’ “close connection” test unduly constricts habeas relief, and which should be construed to encompass not only the need to halt ongoing constitutional violations, but also the need to mitigate various harms that may arise from those violations.

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.

New Hampshire

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.

Vote.Org v. Callanen (Amicus)
Texas requires voters who register to vote electronically or via fax to mail an original copy with the voter’s “wet signature” to the applicable registrar. A voter may be denied registration merely because the mailed copy of the form has a scanned signature on it rather than a “wet ink” one. But the Civil Rights Act prohibits states from disenfranchising voters based on immaterial paperwork errors. We’re fighting to make sure that every vote counts and supported Vote.org’s challenge to the “wet ink” law as unlawful under the Civil Rights Act.

Robinson v. Landry
Robinson challenged the congressional map that Louisiana enacted after the 2020 Census. ACLU and partners represented Plaintiffs the Louisiana State Conference of the NAACP, Power Coalition for Equity and Justice, and several impacted voters, and argued that the enacted plan violated Section 2 of the Voting Rights Act. In June 2022, the district court found Louisiana's congressional map unlawfully denied Black voters a second district in which Black voters had an equal opportunity to elect their candidates of choice. After appeals, the legislature passed a new map containing two majority Black districts in January 2024.

Supporting Defendants in Unlawful Florida Prosecutions of Returning Citizens (Amicus)
Florida has arrested and prosecuted many returning citizens—persons with felony convictions who are no longer incarcerated—for registering and voting while ineligible. These prosecutions have occurred amid widespread confusion about voting rights restoration in Florida and have been initiated by an Office of Statewide Prosecutor (“OSP”) that has no authority to bring these criminal actions.

Jane Doe, et al. v. Daniel Cameron, et al.
A Kentucky woman filed a lawsuit in Jefferson County Circuit Court challenging two of the Commonwealth’s abortion bans that collectively eliminate almost all access to abortion in the Commonwealth. The case details the severe harms that Jane Doe, who is approximately eight weeks pregnant, and a class of all pregnant Kentuckians seeking abortion are enduring because the government has denied her access to the care she needs.

Minnesota Supreme Court
Dec 2023
Criminal Law Reform
State v Malecha
In this case, the Minnesota Supreme Court is considering the scope of a crucial doctrine that protects criminal defendants from being convicted based on evidence obtained in violation of their constitutional rights. Under both the U.S. and Minnesota Constitutions, courts apply an “exclusionary rule” that allows criminal defendants to seek the exclusion of evidence obtained in violation of their rights. For nearly 40 years, the U.S. Supreme Court has chipped away at the exclusionary rule by adopting and expanding the “good faith exception,” a doctrine providing that in some situations courts need not exclude evidence obtained in violation of the Constitution. In this case, officers acquired evidence after arresting someone based on a warrant that was listed as valid due to a recordkeeping error, but which in fact should have been recalled. In July 2023, together with other ACLU attorneys and partners, the SSCI submitted an amicus brief to the Minnesota Supreme Court asking it to hold as a matter of state constitutional law that the exclusionary rule applies to this situation, and that the good-faith exception does not apply. In March 2024, the Court ruled in the ACLU's favor, stating that the district court did not err in finding that the defendant's arrest warrant had been quashed before her arrest and the good-faith exception did not apply.
