EPIC has filed a "friend-of-the-court" brief in Utah v. Strieff, a U.S. Supreme Court case about whether the Fourth Amendment allows evidence to be admitted after an illegal stop. Mr. Strieff was unlawfully detained by an officer, who checked his ID and then arrested him on an unrelated outstanding warrant. In a brief, signed by twenty-one technical experts and legal scholars, EPIC detailed a number of sweeping government databases that contain inaccurate and detailed records about Americans' noncriminal activity. EPIC argued that "a diminished Fourth Amendment standard coupled with a weakened Privacy Act is truly a recipe for a loss of liberty in America." EPIC previously argued against compelled identification during police stops in Hiibel v. Sixth Judicial District and Tolentino v. New York.
