Supreme Court's 'Reasonable Expectation of Privacy' Test Defies Expectations in Geofence Case
The article analyzes the Supreme Court's June 29, 2026 decision in Chatrie v. United States, which held that government-ordered analysis of cellphone location data constitutes a 'search' under the Fourth Amendment. Justice Elena Kagan wrote the majority opinion, finding individuals have a reasonable expectation of privacy in cellphone location records. Justice Neil Gorsuch concurred in the result but criticized the Katz v. United States (1967) 'reasonable expectation of privacy' test as unworkable and lacking constitutional basis. The article traces the origins of the Katz test to Charles Katz, a basketball handicapper whose 1965 arrest led to the landmark Fourth Amendment ruling. It notes the Court's inconsistent application of the test, including the third-party doctrine, and suggests Gorsuch's property-rights approach may offer a more principled alternative. The case involved a Virginia bank robbery investigation where police used a geofence warrant to obtain Google Location History data.
Reason.comUS Supreme Court Rules Broad Phone Location Searches Require Constitutional Protection
The US Supreme Court issued a landmark 6-3 ruling in Chatrie v. United States, holding that individuals have a reasonable expectation of privacy in their mobile device location data, even when that data has been shared with tech companies like Google. The case stemmed from a 2019 armed robbery in Virginia, where police used a geofence warrant to collect location data from all phones near the bank for 30 minutes before and after the crime. The Court stated that such broad sweeps constitute a Fourth Amendment search requiring constitutional protections. However, the justices did not outright ban geofence warrants; instead, they sent the case back to the Circuit Court of Appeals to determine if the specific warrant met requirements of particularity and probable cause. Privacy advocates praised the decision as a check on dragnet surveillance that could protect protesters and other groups from warrantless tracking. Conservative Justices Alito, Thomas, and Barrett dissented. The ruling narrows the scope of cloud-stored data the government can obtain without individualized warrants, potentially complicating police investigations that rely on geofence warrants to identify unknown suspects.
