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.
A Supreme Court ruling could redefine Fourth Amendment protections for location data and change how tech companies store and disclose location information, with wide implications for privacy, law enforcement access, and businesses that collect or monetise location data.

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.
Federal Judge Rules Flock Searches Unconstitutional
A federal judge ruled that a Tulsa sheriff's deputy violated the Fourth Amendment by using Flock Safety's automated license plate reader to search a woman's plate without a warrant. Judge Sara Hill called the practice 'indiscriminate mass surveillance' and suppressed evidence from the search. The ruling is non-binding precedent but signals growing judicial scrutiny of Flock's technology. Flock, which sells surveillance cameras and ALPRs to law enforcement, faces cancellations from states like Florida and Texas, and Senator Bernie Sanders introduced the Block Flock Act to ban federal use. Flock CEO has offered voluntary buyouts amid the backlash.
Lawmakers Split as FISA Section 702 Nears Expiry
Section 702 of the Foreign Intelligence Surveillance Act, which permits U.S. intelligence agencies to collect overseas communications that transit the U.S. without individualized warrants, is set to expire on April 30, 2026. A bipartisan group of senators and representatives is pushing the Government Surveillance Reform Act to curb warrantless practices — including banning 'backdoor searches' of Americans' communications and preventing agencies from purchasing commercial data from data brokers — while the White House has signalled support for a straight reauthorization. The FBI has acknowledged buying Americans' location data without court authorization. Even if Section 702 expires, annual certifications by the Foreign Intelligence Surveillance Court (FISC) and other authorities such as Executive Order 12333 could allow surveillance to continue through March 2027 unless Congress or the courts intervene. Privacy groups including the ACLU, EPIC and POGO support the proposed reforms.
