Supreme Court to hear Chatrie geofence-warrant case Monday; first major Fourth Amendment digital-surveillance argument since Carpenter

SCOTUSblog and CyberScoop reported the Supreme Court will hear oral argument Monday in Chatrie v. United States, in which Virginia bank-robbery defendant Okello Chatrie challenges the FBI's use of a Google geofence warrant that identified devices in a 150-meter, one-hour radius around the 2019 target. It is the first major Fourth Amendment digital-surveillance case the Court has taken since Carpenter v. United States in 2018. Conservative and liberal civil-liberties groups have filed amicus briefs for Chatrie; 32 state attorneys general backed the federal government. Google, which has since shifted location storage onto user devices, filed a brief declining to take a position on the specific warrant but urged the Court to hold Location History and similar remote records within Fourth Amendment protection. A decision is expected by late June or early July.

Analysis
The government's concession of Chatrie's Google opt-in, framing it as distinct from Carpenter's automatic third-party records, signals confidence the Court can keep the ruling narrow. With both the 4th and 5th Circuits having already found geofence warrants unconstitutional, a Solicitor General loss is a roughly even chance by end-of-June. A ruling against the government would very likely force the FBI and state-and-local fusion centers to abandon geofence warrants within weeks of decision, pivoting to individualized targeting or commercial data brokers operating under different Fourth Amendment rules. Google's 2024 migration of Location History onto user devices narrows the practical reach of any outcome regardless of how broadly the opinion reads. The Court may instead dispose of the case on the good-faith exception the Fourth Circuit invoked, sidestepping broader digital-privacy doctrine and leaving IC surveillance tooling unchanged through 2027. Should the opinion reach broader Fourth Amendment territory, particularly financial and chat-log records, state-level surveillance statutes would likely face renewed reform pressure in late 2026, per converging SCOTUSblog and CyberScoop coverage.
