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.

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.

Silver issued an order formally appointing a receiver to assume control and management of health care provided to more than 25,000 people incarcerated in Arizona Department of Corrections, Rehabilitation, and Reentry (ADCRR) prisons, in a long-running lawsuit against the state prison system brought by the Prison Law Office, the American Civil Liberties Union (ACLU), ACLU of Arizona, and Disability Rights Arizona.

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.

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.

Reproductive Freedom
Comprehensive Health of Planned Parenthood Great Plains & Planned Parenthood Great Rivers v. Missouri
The ACLU, ACLU of Missouri, and Planned Parenthood Federation of America are representing Missouri’s two Planned Parenthood providers. Following the passage of Amendment 3, the Right to Reproductive Freedom Initiative, Comprehensive Health of Planned Parenthood Great Plains and Planned Parenthood Great Rivers, filed suit to restore abortion access in the state. The suit seeks to enjoin Missouri’s numerous abortion bans and countless burdensome, medically unnecessary restrictions on abortion that do not improve care or protect patient health. If the requested preliminary relief is granted, Planned Parenthood’s health centers would be able to begin providing abortion in Missouri once more — restoring access to this constitutionally protected health care.

Billard v. Charlotte Catholic High School
Lonnie Billard worked at Charlotte Catholic High School for more than a decade – both as full-time drama and as a long-term substitute teacher – and has won numerous teaching awards, including teacher of the year. In October 2014, Lonnie wrote a Facebook post announcing that he and his long-time partner were getting married. Later that year, the school told Lonnie he could no longer work as a substitute teacher because his engagement and marriage to another man was contrary to the religious principles of the Catholic Church.

Disability Rights
Powers v. McDonough
Every night, thousands of veterans sleep without shelter on the streets of Los Angeles. Meanwhile, the Department of Veterans Affairs owns hundreds of acres of land in prime West Los Angeles—land directly adjacent to a VA medical facility that was once earmarked to house veterans, but today is instead home to private school sports fields and an oil well.
In November 2022, a group of unhoused veterans and a non-profit organization filed suit alleging that the Department of Veterans Affairs (“VA”) failed to provide adequate housing and health care to veterans with severe disabilities in Los Angeles. These failures have significantly undermined veterans’ abilities to access the benefits they are entitled to by law, leaving many stranded on the streets after serving our country. The veterans sued the VA under the Rehabilitation Act, a federal statute that prohibits federal agencies from discriminating against people with disabilities. As a remedy, the plaintiffs seek the construction of significant units of permanent supportive housing on the
The VA argued that a provision of the Veterans’ Judicial Review Act (“VJRA”)— a federal statute that prohibits federal district courts from second-guessing VA’s individualized benefits determinations—bars federal district courts from hearing the veterans’ Rehabilitation Act claims. Should the court accept this position, it would deprive veterans of a meaningful opportunity to have their rights under the Rehabilitation Act and other generally applicable nondiscrimination statutes enforced.

Arizona health care providers filed a lawsuit challenging a ban on abortion after 15 weeks of pregnancy, which is in violation of the state’s new constitutional amendment protecting the fundamental right to abortion. The case, filed in Maricopa County Superior Court, asserts that the ban is unconstitutional because it denies Arizonans access to abortion care in violation of the new constitutional amendment passed by the voters.
