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.

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.

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.

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.

Ayo v. Dunn et al
For years, people arrested in East Baton Rouge Parish who appeared before Judge Trudy White have been jailed unless they pay a $525 fee to a private corporation called Rehabilitation Home Incarceration (“RHI”). This fee is paid by each person for their own pre-trial release. This fee is paid in addition to any bail amount required by the judge as a condition for that person’s release. This has been going on for at least three years in the parish.

Raza v. City of New York - Legal Challenge to NYPD Muslim Surveillance Program
The ACLU, the NYCLU, and the CLEAR project at CUNY Law School filed a lawsuit in June 2013 challenging the New York City Police Department's discriminatory and unjustified surveillance of New York Muslims. We were later joined by the law firm of Morrison & Foerster LLP. The plaintiffs include three religious and community leaders, two mosques, and one charitable organization, all of whom were subject to the NYPD's unconstitutional religious profiling program. In January 2016, we announced a proposed settlement in the case with important reforms that include a bar against NYPD investigations on the basis of race, religion, or ethnicity, and the creation of a civilian representative position to oversee rules that safeguard against discriminatory and unjustified NYPD surveillance. That settlement was a joint one, with both the NYPD and the lawyers in Handschu v. Special Services Division, a long-standing class action that challenged the NYPD’s unlawful surveillance of political groups and activists. In October 2016, the federal district court judge presiding over the Handschu case held that he would approve the settlement if the parties agreed to three alterations, which would further strengthen protections. In March 2017, the courts in both Handschu and Raza approved the revised settlement.

Reproductive Health Services v. Marshall
On July 28, 2017, the U.S. District Court blocked an Alabama law that imposed severe barriers on a minor’s ability to get abortion care in the state. The law, which was passed in 2014, applied to minors who sought a judicial bypass of the state’s parental consent requirement for abortion. It went beyond any other parental consent law in the country and forced minors seeking abortion care to stand trial if they were unable to obtain a parent’s consent for the procedure.

This landmark case is now closed at the behest of the ACLU and the state of Rhode Island because the institution has made the improvements in education, medical care, vocational training, the physical plant, meals, and other conditions required by the consent decree between the state and the plaintiffs.
