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.

New Hampshire
Jul 2026
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.

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.
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.

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.

LGBTQ Rights
Brandt et al v. Rutledge et al
Four families of transgender youth and two doctors have challenged an Arkansas law that would prohibit healthcare professionals from providing or even referring transgender young people for medically necessary health care. The law would also bar any state funds or insurance coverage for gender-affirming health care for transgender people under 18, and it would allow private insurers to refuse to cover gender-affirming care for people of any age. The lawsuit, filed in federal court, alleges that House Bill 1570 is a violation of the U.S. Constitution.

Kentucky Supreme Court

Civil Liberties
Commonwealth v. Davis and Commonwealth v. Kentucky Education Association
This case asks whether Kentucky’s legislature can legally favor some unions by giving them preferential treatment and disfavor others. A recent law does just that: SB 7 prohibits public employers from allowing their employees to use payroll deductions for union dues yet expressly exempts law enforcement and fire protection unions from this prohibition. Two state circuit courts and the Court of Appeals have held that this law violates the Kentucky Constitution’s equal protection guarantee. The State now appeals to the Kentucky Supreme Court. The Court’s decision has important implications for equal protection, free speech, and labor rights in Kentucky.

Michigan Supreme Court

Criminal Law Reform
People of the State of Michigan v. Serges
At the core of this case is the question of whether the government can extract and test our DNA without a warrant. The ACLU’s State Supreme Court Initiative and Project on Speech, Privacy, and Technology, together with the ACLU of Michigan, filed an amicus brief arguing that, since our DNA contains vast amounts of highly sensitive information about us, DNA testing and extraction constitute a search and therefore require a warrant under both the Fourth Amendment to the U.S. Constitution and Article I, section 11 of the Michigan Constitution. If there were no warrant requirement, as the State urges, police would be able to arrest someone for one offense, even pretextually, and limitlessly test their DNA to investigate unrelated crimes. This would especially impact people from marginalized populations who are most likely to be subject to these police practices.

U.S. DOGE Service Access to Sensitive Agency Records Systems Multiagency FOIA
There are serious privacy concerns raised by reports that the United States DOGE (“Department of Government Efficiency”) Service (“USDS”) has gained access to federal agency systems, including those housing sensitive information like federal payment data, student loan data or federal employee records, and may be using artificial intelligence technology in analyzing them. The ACLU submitted a FOIA request to more than 40 federal agencies to provide the public with information on what federal records the agencies have provided to or been asked for by the USDS and if sensitive information and key decision-making has been outsourced to unvetted technology.
