Participated in an amicus brief (with other amici) filed with the U.S. Court of Appeals for the Ninth Circuit in ACLU of Arizona v. U.S. Dept. of Homeland Security. The case involved a Freedom of Information Act request by the American Civil Liberties Union of Arizona that was denied by the U.S. Department of Homeland Security. The ACLU sought information about how DHS investigates its agents accused of child abuse. The brief argued that the DHS claim of exemption violated U.S. Supreme Court and Ninth Circuit precedents and that the agents’ personal privacy interest did not overcome the public’s interest in disclosure.
