The American Civil Liberties Union, the ACLU of Ohio, Planned Parenthood Federation of America, the law firm WilmerHale, and Fanon Rucker of the Cochran Law Firm, on behalf of Planned Parenthood Southwest Ohio Region, Planned Parenthood of Greater Ohio, Preterm-Cleveland, Women’s Med Group Professional Corporation, Dr. Sharon Liner, and Julia Quinn, MSN, BSN, amended a complaint in an existing lawsuit against a ban on telehealth medication abortion services to bring new claims under the Ohio Reproductive Freedom Amendment, including additional challenges to other laws in Ohio that restrict access to medication abortion in the state.

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of naturalized American citizens to improper investigations questioning their voting eligibility, and they’re using outdated, faulty data and methods to do so.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.

ARKK Properties v. Cameron
In 2023, the Kentucky General Assembly passed a new law that targets only those Kentuckians who “challenge the constitutionality” of a state statute or similar law and seek relief against a state defendant in state court. Under S.B. 126, any party to a covered lawsuit will have a unilateral right to require transfer of the case from the circuit court where it was properly filed to a randomly chosen circuit anywhere else in the state, potentially hundreds of miles away and at great cost to Kentuckians who stand up for their rights. The ACLU of Kentucky, the Kentucky Equal Justice Center, and the Kentucky Resources Council—with representation from attorneys at the ACLU of Kentucky and the ACLU’s State Supreme Court Initiative—filed an amicus brief in the Kentucky Supreme Court, asking the Court to hold that the law violates the Kentucky Constitution. In October, the Kentucky Supreme Court invalidated S.B. 126, ruling in favor of the ACLU.

Planned Parenthood Association of Utah v. State of Utah
This case involves a challenge to Utah Senate Bill (“S.B.”), a law that criminalizes nearly all abortions in Utah. In June 2022, Planned Parenthood Association of Utah (“PPAU”), one of only two abortion providers in the state, challenged S.B. 174 in Utah state court. It is currently litigating in the Utah Supreme Court to ensure the law remains blocked while courts consider the case. PPAU is represented in the appeal by the ACLU’s State Supreme Court Initiative, along with the ACLU of Utah, Planned Parenthood Federation of America, and the Utah law firm Zimmerman Booher. In August 2024, in a major win for Utahns, the Court affirmed the lower court order blocking SB 174. As a result, abortion remains legal in Utah until 18 weeks of pregnancy.
