United States v. Alaska
Representing two Alaska voters, the League of Women Voters of Alaska, and Common Cause, the American Civil Liberties Union and ACLU of Alaska moved to intervene in United States v. Alaska, a frivolous lawsuit seeking to prevent from the State of Alaska from certifying its election results if the incumbent U.S. Senator does not win the election. The lawless suit asserts a single claim based on the purpose language of the National Voter Registration Act (NVRA), that has no basis in any case, legal principle, or arguably tenable reading of the NVRA.
We are seeking dismissal of this suit that aims to deprive Alaskans of their right to vote and right to representation.

OCA-Asian Pacific American Advocates v. Department of Homeland Security
The Department of Homeland Security and United States Citizenship and Immigration Services are subjecting thousands of naturalized American citizens to improper investigations questioning their voting eligibility, and they’re using outdated, faulty data and methods to do so. As a result, these citizens face increasing, unwarranted scrutiny from the federal government and, potentially, disenfranchisement. We’re challenging these unlawful actions and the unreliable data behind them to ensure no eligible voter is targeted or silenced because of them.

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.

Daves v. Mosley
Section 131 of the newly enacted Enhance Law Enforcement Integrity Act gives Coloradans a cause of action to seek damages or equitable relief when state or local police officers violate the Colorado Constitution. In 2022, Christopher Mosley sued Officer Brendan Daves for conducting a warrantless search of his car, which Daves argued was lawful under the federal protective sweep doctrine. After Mosley prevailed at trial and the court of appeals affirmed, Daves appealed to the Colorado Supreme Court. The ACLU’s State Supreme Court Initiative and the ACLU of Colorado filed an amicus brief agreeing with Mosley’s argument that Daves has misapprehended the federal doctrine whilst focusing on a separate point: the Court’s interpretation of Section 131 is not bound by federal law.

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.

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.

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.

Voting Rights
United States v. Raffensperger
The Department of Justice sued Georgia, demanding the state produce its full, unredacted voter file, which contains highly sensitive and personal data on every voter in the state. This suit appears to be part of the DOJ’s efforts to build a national voter database without congressional authorization, improperly question the validity of state voter rolls, and intimidate eligible voters in Georgia and across the country.

Poe et al. v. Harris-Madden et al.
The ACLU, NYCLU, Family Justice Law Center, Brooklyn Defender Services, Center for Family Representation, NYU School of Law Family Defense Clinic, and Sullivan & Cromwell have filed a federal class action lawsuit on behalf of three New York parents challenging unconstitutional delays in the appeals process for reports on the Statewide Central Register of Child Abuse and Maltreatment (SCR). Parents who challenge their placement on the registry often wait months—sometimes more than a year—for a final decision. While they wait, they can be shut out of jobs in childcare, education, healthcare, and other fields involving children, and barred from adopting or fostering. Low-income parents, parents of color, and disabled parents are disproportionately policed by the family regulation system—also known as the child welfare system—and more likely to end up on the registry. This lawsuit seeks to ensure that parents have a way to clear their names in a timely manner.

Reproductive Freedom
Planned Parenthood Southwest Ohio Region, et al. v. Ohio Department of Health, et al.
In December 2020, Ohio Governor Mike DeWine signed into law Senate Bill 27, a fetal tissue disposal requirement that mandates burial or cremation of all embryonic and fetal tissue from a procedural abortion, imposing severe burdens on patients and stigmatizing essential care. On January 31, 2022, an Ohio judge preliminarily enjoined the law, finding that the law likely violates the Ohio state constitution’s guarantees of due process and equal protection. The victory followed a previous April 5, 2021, preliminary injunction halting enforcement of the law, because compliance would have been impossible due to the Ohio Department of Health’s (ODH) failure to establish necessary rules and regulations.
In April 2024, Plaintiffs filed a Second Amended Complaint, adding a claim that the law violated the newly established Right to Reproductive Freedom Amendment of the Ohio Constitution, and in August 2024 filed a 12(C) Motion for Judgment on the Pleadings, arguing that Senate Bill 27 is unconstitutional as a matter of law under that Amendment for discriminatorily targeting procedural abortion. In February 2025, the Hamilton County Court of Common Pleas agreed, granting the Motion for Judgement on the Pleadings and permanently enjoining enforcement of Senate Bill 27.
In February 2026, the Ohio First District Court of Appeals upheld the trial court’s permanent injunction, ruling that the requirements under Senate Bill 27 violate the state constitution’s Reproductive Freedom Amendment, which took effect in December 2023 after being approved by voters.
This lawsuit was filed by the American Civil Liberties Union, ACLU of Ohio, Planned Parenthood Federation of America, and Fanon Rucker of the Cochran Law Firm on behalf of Ohio abortion providers.
