Google urges Supreme Court to strike down geofence warrants as unconstitutional

(Suzanne Smalley – The Record) With the Supreme Court poised to rule for the first time on the constitutionality of geofence warrants, Google on Monday filed a brief with the high court arguing that the law enforcement tool is unconstitutional. A geofence warrant is also known as a “reverse search warrant” because they let police demand technology companies pinpoint all mobile devices present in a specific geographic area during a particular time span. Geofence warrants help police find suspects, but sweep up the location of many innocent people, creating privacy and civil liberties concerns, critics say. In July 2025, Google began storing all location history data on-device so that it is no longer able to respond to geofence warrants at all. The Supreme Court’s decision could still affect other tech companies whose practices haven’t changed and historic cases which Google may be asked to respond to. – Google urges Supreme Court to strike down geofence warrants as unconstitutional | The Record from Recorded Future News
