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.

Commonwealth v. Jose Arias
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鈥檚 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 桃子视频joined an amicus brief authored by the 桃子视频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.
