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.
U.S. Supreme Court

Voting Rights
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.
Massachusetts
Apr 2026
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.
Missouri
Apr 2026
Voting Rights
Wise v. Missouri
In unprecedented fashion, the State of Missouri has redrawn the district lines used for electing members of Congress for a second time this decade. These new district lines are gerrymandered and will harm political representation for all Missourians, particularly Black residents in Kansas City, who have been divided along racial lines.
Tennessee Supreme Court
Apr 2026
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.
Mississippi
Dec 2025
Voting Rights
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.
U.S. Supreme Court

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.
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.

National Security
Alario v. Knudsen (Amicus)
In April 2023, Montana’s state legislature passed SB 419, an Act Banning TikTok in Montana. This law imposes a sweeping ban on free expression—one that would prevent everyday Montanans from using TikTok to communicate with immense audiences, access information from around the world, and express themselves. This ban flouts the First Amendment and tramples Montanans’ constitutional right to freedom of speech—that’s why the ACLU, ACLU of Montana, Electronic Frontier Foundation (EFF), and a coalition of civil society organizations filed amicus briefs in the district court and the Ninth Circuit urging the courts to block the law from going into effect. Through these briefs, we continue to fight to ensure that no legislature can ban Americans from using an immensely popular platform for online speech based on vague invocations of “national security” or anti-China rhetoric.

Pennsylvania Supreme Court

Civil Liberties
Penncrest School District v. Cagle
This case in the Pennsylvania Supreme Court asks whether the Right to Know Law (“RTKL”), 65 P.S. §§ 67.101 - 67.3104, requires the disclosure of school board members’ social media posts on their private Facebook accounts relating to the propriety of a display of certain books in the school library. This case is among one of the first state supreme court cases addressing whether Facebook posts constitute records. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Pennsylvania and the Pennsylvania attorney Brian Cagle, filed a brief arguing that RTKL’s text and structure require the conclusion that posts are “records,” and thus are subject to disclosure.

State v. Ochoa
This case in the Texas Court of Criminal Appeals concerns the admissibility of a fourteen-year-old defendant’s confession following a Texas Ranger’s coercive interrogation. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Texas, filed an amicus brief arguing that the defendant’s confession was induced by positive promises, and is inadmissible, particularly given his juvenile status and the circumstances of the interrogation. In November 2024, the Texas Court of Criminal Appeals (the highest court for criminal appeals in Texas) ruled that Holland's interrogation of Ochoa was unconstitutionally coercive in violation of Ochoa's Fourteenth Amendment due process rights.

Held v. Montana
In 2020, in Held v. Montana, sixteen youth plaintiffs challenged Montana’s energy policy as violating the Montana Constitution. After several years of litigation, the Montana Supreme Court affirmed that Montanans have a constitutional right to a clean and healthful environment.
In January 2026, Montana youth filed a second case, Held II, to enforce the Court’s decision after the Legislature enacted new laws that the plaintiffs contend undermine the constitutional protections recognized in the Court’s earlier decision and permit continued approval of fossil fuel projects that worsen climate harms.
The State moved to transfer Held II to a different district under SB 97, a law that gives the government a special right to forum shop in cases challenging new laws and makes it significantly harder for Montanans to pursue such challenges. SB 97 thus raises serious access-to-justice concerns in this case and any others in which people are seeking relief from allegedly unconstitutional laws.
