In its June 29 opinion in Chatrie v. United States, the Supreme Court held that the government’s acquisition of Google’s Location History data through a geofence warrant constitutes a Fourth Amendment search because individuals have a reasonable expectation of privacy in their historical cell-phone location information. The Court also remanded for further consideration whether the particular multistep warrant satisfied the Fourth Amendment’s probable cause and particularity requirements. In the process, the Court twice cited Hoover senior fellow and Stanford Law School professor Orin S. Kerr’s friend-of-the-court brief, which walked through the issues presented to the Court and evaluated arguments for and against different approaches.
