CAIR-Foundation, Inc and CAIR Florida, Inc. v. DeSantis et al.
The ACLU, the ACLU of Florida, the Southern Poverty Law Center, and their partners represent CAIR and CAIR-Florida in two federal lawsuits challenging Governor DeSantis’s unconstitutional and baseless designation of the nonprofits as “terrorist.” The lawsuits allege violations of CAIR and CAIR-Florida’s rights under the First Amendment and the due process clause of the Fourteenth Amendment.

Common Cause v. U.S. Department of Justice
The U.S. Department of Justice has launched an unprecedented and unlawful effort to invade the privacy of millions of American voters and threaten their right to vote. It has demanded that every state and the District of Columbia turn over their entire voter database, including Social Security Numbers, political party affiliation, and voter participation history. And at least a dozen states have complied, submitting their voters’ information for federal review. But the Department of Justice has no authority to dictate when a voter registration should be cancelled, and we are suing to stop the federal government’s overreach and ensure that voters’ information remains secure and free from unlawful interference.

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.

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.

Prisoners' Rights
Zyst v. Miller
Following the Oregon Department of Corrections’ unconstitutional treatment of a transgender prisoner, a habeas court ordered her removal from segregated housing, an individualized gender-affirming care assessment, a psychiatric evaluation, and identification of an appropriate cellmate. However, the Oregon Court of Appeals reversed the psychiatric-evaluation and cellmate orders, finding them “too attenuated” to qualify as habeas relief. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Oregon, joined an amicus brief by the law firm Sugerman Dahab arguing that habeas courts have broad discretion to remedy violations and resulting harms. The brief explains that the Court of Appeals’ “close connection” test unduly constricts habeas relief, and which should be construed to encompass not only the need to halt ongoing constitutional violations, but also the need to mitigate various harms that may arise from those violations.

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.

South Carolina Supreme Court
Nov 2024
Reproductive Freedom
Planned Parenthood South Atlantic v. Wilson
This case in the South Carolina Supreme Court involves the question of whether a ban on abortion, the “2023 Fetal Heartbeat Act,” forbids abortion starting after approximately nine weeks of pregnancy or, as the state contends, earlier at six weeks of pregnancy, before many people even know they are pregnant. This case is the third state supreme court proceeding in South Carolina involving a post-Dobbs challenge to an abortion ban. The outcome will substantially affect access to reproductive care in the state.

Pennsylvania Supreme Court

Criminal Law Reform
Commonwealth of Pennsylvania v. Shivers
This case in the Pennsylvania Supreme Court asks whether flight from the police in a high-crime area, without more, can justify an investigative stop. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Pennsylvania, filed an amicus brief arguing that it does not. The brief argues that the Pennsylvania Constitution supports broader protections against investigative stops than those recognized under the U.S. Constitution, and that flight in high-crime areas is not inherently more suspicious than flight elsewhere.

Ayota v. Fall
On October 31, 2024, just five days before the November 5 General Election, Cobb County announced that it had failed to send more than 3,000 absentee ballots to Cobb County voters who had timely requested them. Many of these voters are at school hundreds of miles away or have disabilities that make it all but impossible to vote in person. The ACLU and co-counsel sued on behalf of affected voters to ensure that they would not be disenfranchised because of the County's administrative error.
