Supreme Court ruling guts government’s use of geofence warrants

The Supreme Court ruled 6-3 that law enforcement must obtain a warrant before accessing location history data collected by tech companies like Google, significantly constraining geofence warrant practices used in criminal investigations. This decision expands Fourth Amendment protections to location data regardless of how much is accessed or whether users voluntarily shared it with third parties, creating new compliance obligations for IT organizations that manage location data and increased friction for law enforcement data requests. Technology leaders should expect rising legal scrutiny of location-tracking features, mandatory warrant verification processes, and potential liability if systems fail to properly enforce access controls or audit trails around geolocation information.
