Lawfare No Bull: Supreme Court Hears Oral Arguments on the Constitutionality of Geofence Warrants

Today on Lawfare No Bull: On April 27, the Supreme Court heard oral arguments in the case of Chatrie v. United States, centering on a Fourth Amendment challenge to the use of geofence warrants, which allow investigators to obtain location data stored by a service provider within a specific geographic area and time period. Over the course of two hours, the justices questioned Petitioner’s Counsel Adam G. Unikowsky and Deputy Solicitor General Eric J. Feigin on how such geofence warrants comport with the Fourth Amendment's Reasonable Expectation of Privacy and its Search and Seizures Clause, the role of service providers’ disclosures and data storage processes, how the challenge fits with precedent set in the Court’s 2017 decision in Carpenter v. U.S., and more.
