Adam Blocker v. United States

This Court’s decision last Term in Chatrie v. United States, 146 S. Ct. 2193 (2026), reaffirmed that a user does not forfeit his or her Fourth Amendment rights merely by conveying information to a thirdparty technology company in the ordinary course of using its services: “A cell-phone user is not to be viewed as sharing private information with third parties—which then can be freely passed on to the government—just by doing the ordinary things cell-phone users do.” Id. at 2214-2215. The question presented is: Whether—in light of Chatrie—a user’s agreement to terms of service reserving the service-provider’s right to review a user’s files and disclose them to third parties authorizes a warrantless governmental search of those files.
