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.

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.

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.

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.

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.

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.

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.

State Board of Election Commissioners v. Mississippi State Conference of the NAACP
Mississippi has a growing Black population, which is already the largest Black population percentage of any state in the country. Yet. Black Mississippians continue to be significantly under-represented in the state legislature, as Mississippi’s latest districting maps fail to reflect the reality of the state’s changing demographics. During the 2022 redistricting process, the Mississippi legislature refused to create any new districts where Black voters have a chance to elect their preferred representative. The current district lines therefore dilute the voting power of Black Mississippians and continue to deprive them of political representation that is responsive to their needs and concerns, including severe disparities in education and healthcare.

Maine Supreme Court
Nov 2023
Free Speech
State v. Labbe
This free-speech case concerns a prosecution for “stalking” based on evidence of a defendant’s speech alone, without any requirement of subjective intent. Freedom of speech is a bedrock protection of both the Maine Constitution and the United States Constitution. This protection requires, at minimum, that a criminal defendant cannot be prosecuted for stalking carried out via speech alone unless the state proves a subjective-intent element beyond a reasonable doubt. This protection ensures that states do not prosecute and punish people for their protected speech. In October 2023, the ACLU and the ACLU of Maine filed an amicus brief in the Supreme Judicial Court of Maine, asking the court to vacate a defendant’s stalking conviction that was based on his speech alone, without any evidence as to subjective intent.

Sellers v. People
In September 2023, the ACLU, the ACLU of Colorado, The Boston University Center for Antiracist Research, the law firm Mintz Levin, and other partners filed an amicus brief with the Colorado Supreme Court arguing that mandatory life-without-parole (LWOP) sentences for strict liability felony murder are “cruel and unusual” in violation of the Colorado and U.S. Constitutions. The brief focuses on how these mandatory LWOP sentences drive racial injustice.

Commonwealth of Kentucky v. Graham (Amicus)
State legislatures are responsible for creating state legislative and U.S. congressional districts. In 2019, the U.S. Supreme Court held in Rucho v. Common Cause that federal courts have no authority to review claims that states have sorted voters along partisan lines to favor one political party over others. However, challenges to partisan gerrymandering continue in many state courts, and this case involves one such constitutional challenge in Kentucky.

Students for Justice in Palestine at the University of Florida v. Raymond Rodrigues
The University of Florida chapter of Students for Justice in Palestine filed a lawsuit on November 16, 2023, challenging the Chancellor of the State University System of Florida’s order to state universities to deactivate the student group. This order threatens the students’ constitutionally-protected right to free speech and association in violation of the First Amendment. The ACLU and its partners are seeking a preliminary injunction that would bar the Chancellor and the University of Florida from deactivating the UF SJP.

Barrani v. Salt Lake City
Hundreds if not thousands of Salt Lake City, Utah, residents have nowhere safe to stay and must live and sleep in public. This case—brought by a small group of residents and businesses—involves the question whether this citywide homelessness crisis constitutes a nuisance under Utah state law. It also presents the question whether Salt Lake City can be ordered to clear encampments, forcibly relocate people who are unhoused, and enforce vague and overbroad laws criminalizing homelessness where doing so will likely, if not certainly, violate unhoused people’s state and federal constitutional rights. The ACLU’s State Supreme Court Initiative and Trone Center for Justice and Equality, along with the ACLU of Utah and the Salt Lake Legal Defenders Association, represent amici curiae in the trial court who oppose the plaintiffs’ nuisance claims and their request for relief.
