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.

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.

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.

Prisoners' Rights
State v. Morris
This case in the Ohio Supreme Court concerns the scope of the state constitutional right to counsel. The police in this case interrogated the defendant, Isaiah Morris, without mentioning his already-appointed counsel or asking him to waive his right to counsel. This procedural circumstance risks confusing criminal defendants and undermining their state constitutional rights. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Ohio and WilmerHale, filed an amicus brief arguing that merely providing a defendant notice of Miranda rights falls short of the bare minimum requirements for a valid waiver.

ACLU of Michigan v. Froman
Michigan requires boards of county canvassers to certify the results of an election within 14 days after the election based on the total number of votes reported from each location.

This lawsuit asks the state's courts to make clear that Mr. Froman is duty bound to certify the election based on the number of votes reported.

Capital Punishment
Abdullahi Khalif Noor v. Melissa Andrewjeski
Abdullahi Khalif Noor is a Somali refugee, who was a cab driver living in Seattle when convicted of rape and assault, and sentenced to life imprisonment. He has always maintained his innocence. He challenged his convictions in Washington state courts, arguing that prosecutors had suppressed evidence of his innocence in violation of due process and Brady v. Maryland.
Unsuccessful in the Washington state courts, he filed a petition for a writ of habeas corpus in federal district court. He was again unsuccessful, and sought to appeal to the U.S. Court of Appeals for the Ninth Circuit. Ordinarily, when a party loses in federal district court they can immediately appeal the decision. But Mr. Noor was barred from doing so because he had not obtained a document Congress has required habeas petitioners receive from federal courts before they can appeal since 1908 — then called a certificate of probable cause, but now called a certificate of appealability (COA).
