Last fall, Proskauer attorneys filed an amicus brief on behalf of the American Civil Liberties Union (ACLU) and ACLU of Massachusetts (ACLUM) in Commonwealth v. Arias, SJC-13816. On April 15, 2026, the Massachusetts Supreme Judicial Court issued its opinion in the case, holding that police violated Article 14 of the Massachusetts Declaration of Rights by waiting more than 24 hours to stop Jose Arias after observing him commit a civil traffic infraction while tailing him as part of a drug investigation. The SJC reversed the denial of Mr. Arias’s Motion to Suppress, vacated his conviction, and remanded the case to the Superior Court.
