The Department of Justice (DOJ) sued the Massachusetts Secretary of State Galvin, seeking private, confidential voter data. DOJ’s efforts appear to be part of an effort to build a national voter database without congressional authorization and to improperly question the validity of state voter rolls.

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.

On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commission—an agency that Congress specifically established to be bipartisan and independent—to require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.

This case asks whether the stop, search, and arrest of an individual after a traffic stop was unconstitutional under the Massachusetts Declaration of Rights. The case arises from a remarkable set of facts: although motivated by a desire to search Mr. Arias’s car for drugs, the police initiated the stop based on a day-old alleged traffic infraction and then arrested Mr. Arias for allegedly neglecting to stop his car immediately when the police initiated the stop. The ACLU joined an amicus brief authored by the ACLU of Massachusetts and the law firm Proskauer Rose, which argues that the police actions in this case were unconstitutional for three reasons. First, pretextual traffic stops, such as this one, violate the Massachusetts Declaration of Rights. Second, arrests for misdemeanors not involving breaches of the peace also violate the Massachusetts Declaration of Rights. Third, the statute prohibiting drivers from neglecting to stop is unconstitutionally vague as applied to this case.
