Chatrie and the Future of the Fourth Amendment
Summary
Host Julie Silverbrook and Stanford Law Professor Orin Kerr analyze the Supreme Court’s decision in *Chatri v. United States*, which ruled that geofence warrants violate the Fourth Amendment. They discuss how the ruling expands digital privacy protections by limiting the third-party doctrine and treating location data as private, even when voluntarily shared with tech companies. The episode also explores the legal implications for future surveillance, contrasting the majority’s privacy-focused approach with dissenting opinions that favor traditional property-based interpretations.
