Supreme Court Rules Geofence Warrants Need Warrants
The U.S. Supreme Court ruled 6-3 that individuals have a reasonable expectation of privacy in cellphone location information and that authorities must obtain a search warrant to compel tech companies for historical geofence location data. The decision centered on Chatrie v. United States and does not ban geofence warrants outright but requires warrants supported by probable cause and narrower requests. The Court rejected a blanket application of the third‑party doctrine to location histories held by companies such as Google, while leaving lower courts to decide whether the specific warrant in Chatrie met the probable‑cause standard. The ruling may force changes in how companies store and disclose location data and has broad implications for privacy, law enforcement practice, and access to device-derived location signals used across industries.
Supreme Court ruling clarifies Fourth Amendment protections for device-derived location data, requiring warrants for geofence requests; this fundamentally affects how companies, law enforcement and downstream industries access and handle location signals used in advertising, measurement, and product design.

- The Court held that authorities must obtain a search warrant to compel tech companies (for example, Google) to produce historical geofence location data.
- The ruling arose from Chatrie v. United States, where Okello Chatrie challenged evidence obtained via a geofence warrant used in his bank robbery trial.
- The Court did not ban geofence warrants outright but required that warrants be supported by probable cause and that requests be narrowly tailored.
- Companies that commonly receive geofence warrants include Google, Microsoft, Uber, and Yahoo; some companies have begun storing location data on devices instead of servers.

Supreme Court Split on Geofence Search Warrants
The U.S. Supreme Court heard oral arguments on April 28, 2026 in Chatrie v. United States, a key Fourth Amendment case challenging law enforcement’s use of “geofence” search warrants that compel tech companies to turn over location data for all devices within a specified area and time. The practice, used increasingly since 2016, lets investigators search broad location datasets to identify potential suspects; privacy advocates say it is overly broad and unconstitutional. Justices appeared divided during arguments, suggesting the court may narrow rather than entirely ban geofence warrants. The decision, expected later in 2026, could reshape legal standards for location data privacy and affect how companies that collect location information respond to government demands.
Supreme Court Upholds FCC Fines Against Wireless Carriers
The U.S. Supreme Court ruled 8-1 that the Federal Communications Commission may use its internal enforcement procedures to assess fines against major wireless carriers without violating the Seventh Amendment. Chief Justice John Roberts wrote the majority opinion, finding FCC forfeiture orders are initial assessments that do not bar later judicial review or a jury trial if the government pursues collection in federal court. The case concerned millions in penalties for carriers allegedly sharing customers' location data without proper consent — nearly $200 million in total across carriers (including AT&T, Verizon, T-Mobile and Sprint). Justice Clarence Thomas dissented. The decision affirms the FCC’s enforcement authority and has implications for telecom privacy practices, carrier compliance programs, and regulator oversight of location-data commercialization.
FBI Resumes Buying Americans' Location Data, Sparks Outrage
FBI Director Kash Patel told lawmakers the agency has resumed purchasing commercially available data, including Americans’ location histories, from data brokers to support federal investigations. The testimony — the first explicit confirmation since 2023 — said purchases are consistent with the Constitution and the Electronic Communications Privacy Act. Senators including Ron Wyden criticized agencies buying location data without warrants as undermining Fourth Amendment protections. The article notes data brokers source much of this information from consumer phone apps and that ad‑tech systems such as real‑time bidding (RTB) can be a source for location signals; U.S. Customs and Border Protection previously purchased RTB‑sourced data, according to reporting. Lawmakers have introduced the Government Surveillance Reform Act, a bipartisan bill that would require a court‑authorized warrant before federal agencies buy Americans’ information from data brokers.
