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.
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.
Massachusetts

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.

Whether the congressional map Louisiana adopted to cure a Voting Rights Act violation in Robinson v. Ardoin is itself unlawful as a gerrymander.

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.

White v. Mississippi State Board of Elections
District lines used to elect Mississippi’s Supreme Court have gone unchanged for more than 35 years. We’re suing because the current lines crack the Mississippi Delta and dilute the voting strength of Black Mississippians in state Supreme Court elections, in violation of the Voting Rights Act.
Washington, D.C.
Oct 2025
Voting Rights
League of Women Voters Education Fund v. Trump
On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commission—an agency that Congress specifically established to be bipartisan and independent—to require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.
On behalf of leading voter registration organizations and advocacy organizations, the ACLU and co-counsel filed a lawsuit to block the Executive Order as an unconstitutional power grab.

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. The law doesn't allow them to withhold certification. Kalamazoo Board of County Canvassers member, Robert Froman, has made clear that he would decline to certify the November 2024 election under certain circumstances. 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.

Abhiraman v. State Election Board (Amicus)
The Georgia’s State Election Board recently passed two new rules about local election certification that threaten to disenfranchise thousands of Georgia voters. The rule changes are part of a nationwide effort by 2020 election-deniers to obtain positions on county election boards and weaponize certification for partisan ends at the expense of voters.

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).
