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.

ACLU v. DOD – FOIA Case Seeking Biden Administration’s Presidential Policy Memorandum

Commonwealth v. Kurtz
“Reverse searches” are a novel surveillance technique where the police can obtain records reflecting everyone who used a search engine to look up a particular word or phrase. In this case, the lower court approved the police using a reverse search, ruling that people do not have a reasonable expectation of privacy for any query they enter into a search engine. The ACLU’s Speech, Privacy, and Technology Project and State Supreme Court Initiative along with the ACLU of Pennsylvania filed an amicus brief in the Pennsylvania Supreme Court urging the court to reverse the lower court’s decision and hold that search history data is protected by the state and federal Constitution.
