Court Cases

In December 2025, the ACLU of Massachusetts and the ACLU Voting Rights Project filed a motion to intervene on behalf of Common Cause, Jane Doe Inc., and a Massachusetts voter in United States of America v. Galvin to prevent the U.S. Department of Justice from obtaining Massachusetts voters’ personal data. In July 2025, the DOJ asked Massachusetts to turn over voters’ full names, dates of birth, addresses, driver’s license numbers, and partial Social Security numbers — highly sensitive data protected under state and federal law. Massachusetts Secretary of the Commonwealth William F. Galvin appropriately declined to share this sensitive data. The United States then filed this lawsuit — one of at least twenty-five nearly identical actions the DOJ has initiated against states and election officials — seeking to compel the production of sensitive Massachusetts voter data. According to extensive public reporting, corroborated by government documents, the DOJ’s requests for private, sensitive voter data from Massachusetts and other states appear to be in connection with novel efforts to construct a national voter database, and to otherwise use untested forms of database analysis to scrutinize state voter rolls and challenge voters’ eligibility. In their motion to intervene, the parties argue that the DOJ’s request threatens voter privacy and could enable voter disenfranchisement. The parties’ motion to intervene was allowed on January 6, 2026. On behalf of the intervenors, the ACLU has since filed a motion to dismiss the DOJ’s complaint. The intervenors argue that the United States seeks to compel disclosure of sensitive voter information to which it is not entitled. Neither the information requests propounded by the DOJ, nor the complaint itself provide the “basis and the purpose” for the DOJ’s requests as required under the Civil Rights Act of 1960, under which the DOJ brings suit. The intervenors argue that the DOJ is grossly misusing civil rights era statutes to reach discriminatory and illegal ends. Additionally, the intervenors argue that the DOJ’s stated reason for requesting millions of Massachusetts voters’ personal data is pretextual. Public reporting and publicly available government documents confirm that the United States’s actual purpose is not to ensure compliance with federal statute, but to compile an unprecedented national voter file using error-prone forms of data-aggregation and then to use this tool to identify and mass-challenge ostensibly ineligible voters. Common Cause, an intervenor in the case, is a nonpartisan, grassroots organization dedicated to upholding the core values of American democracy. Jane Doe Inc. is a coalition of organizations dedicated to advocating on behalf of survivors of sexual and domestic violence. The group has an interest in protecting the privacy of survivors. Juan Pablo Jaramillo, a naturalized U.S. citizen, is also represented in the case. Jaramillo has an interest because his status as a naturalized citizen may place him at a heightened risk of being targeted for voter disenfranchisement, a threat that extends to countless other Massachusetts voters.

On October 14, 2025, the United States military carried out an illegal missile strike that killed Chad Joseph and Rishi Samaroo, two Trinidadian men who were traveling by boat from Venezuela to their homes in Las Cuevas, Trinidad and Tobago. The American Civil Liberties Union, the Center for Constitutional Rights, the American Civil Liberties Union of Massachusetts, and Professor Jonathan Hafetz of Seton Hall Law School filed suit on behalf of Lenore Burnley, Mr. Joseph’s mother, and Sallycar Korasingh, Mr. Samaroo’s sister, seeking redress and accountability for these extrajudicial killings pursuant to the Death on the High Seas Act and the Alien Tort Statute.

In December 2025, the ACLU of Massachusetts filed a federal lawsuit on behalf of our client, Carlos Zapata Rivera. The lawsuit alleges that an ICE agent unlawfully applied a carotid restraint to Mr. Zapata Rivera while arresting him on Nov. 6, 2025, then refused him prompt emergency medical care. Mr. Zapata Rivera, a resident of Fitchburg, Massachusetts, was driving his wife to work with their one-year-old daughter in the car when they were pulled over by several ICE agents. The agents informed Mr. Zapata Rivera’s wife that they intended to arrest her. The lawsuit alleges an unidentified ICE agent, listed in the lawsuit as Agent John Doe, climbed into the vehicle and pressed his thumbs forcefully on Mr. Zapata Rivera’s carotid arteries, restricting blood flow to his brain. Mr. Zapata Rivera lost consciousness, and he experienced involuntary seizure-like movements. The ICE agent continued to apply the carotid restraint with at least one hand while these involuntary movements continued. The Department of Homeland Security’s own policies prohibit agents from using carotid restraint techniques except when deadly force is justified. The lawsuit also alleges that ICE agents refused to allow Mr. Zapata Rivera to be evaluated by emergency medical personnel at the scene. After his release, he continued to suffer severe physical symptoms and went to the emergency room for treatment. The Department of Homeland Security’s public statements about the incident accused Mr. Zapata Rivera of faking a seizure and refusing medical care. An immigrant from Ecuador, Mr. Zapata Rivera applied for asylum in early 2024 and has been authorized to work in the United States while that application is pending. After his counsel sent a letter to ICE requesting that the agency preserve evidence relating to this incident, ICE abruptly sent Mr. Zapata Rivera a “call-in letter” demanding that he appear with his passport at ICE’s Burlington office at 10 a.m. on Thursday, Dec. 18, 2025. It was the first time he had received such a request since early 2023.

In July 2025, the ACLU of Massachusetts, together with the ACLU, law firm Rubin Pomerleau, P.C., and Boston College Law School Immigration Clinic filed a lawsuit in federal court challenging the detention of an 18-year-old under the Laken Riley Act (LRA). The habeas petition alleges “John Doe”...

In September 2025, the American Civil Liberties Union of Massachusetts, together with the ACLU’s Immigrants’ Rights Project, the ACLU of New Hampshire, the ACLU of Maine, the law firm Araujo and Fisher, the law firm Foley Hoag, and the Harvard Immigration and Refugee Clinic, filed a class action lawsuit in federal court to challenge the widespread denial of bond hearings to people detained by U.S. Immigration and Customs Enforcement. As the complaint demonstrates, this denial upends decades of settled law and established practice in immigration proceedings. The complaint alleges that the U.S. Department of Homeland Security and the Department of Justice recently and abruptly began to misclassify people arrested by ICE inside the United States. DHS and DOJ started systematically reclassifying these people from the statutory authority of 8 U.S.C. § 1226, which usually allows for the opportunity to request bond during removal proceedings, to the no-bond detention provisions of 8 U.S.C. § 1225, which does not apply to people arrested in the interior of the United States and placed in removal proceedings. This case is brought on behalf of Jose Arnulfo Guerrero Orellana and a putative class of similarly situated individuals. Mr. Guerrero Orellana has been living in the United States for over a decade. He brings this case to vindicate his own right to a bond hearing — where an immigration judge can determine whether his detention is justified to protect the community or ensure his appearance in court — and that of thousands of other detainees in Massachusetts, Rhode Island, Maine, and New Hampshire who will be denied the opportunity to seek release on bond under the new legal ruling adopted by the executive branch. The complaint alleges that the government's new policy violates constitutional and statutory due process rights as well as the Administrative Procedure Act.
