Lower courts have offered different approaches to these questions, reflecting the difficulty of applying traditional Fourth Amendment doctrine to the digital age.

Chatrie sits at the intersection of those precedents, raising the question whether sweeping geofence warrants fit within existing doctrine, or represent something fundamentally different in scope and scale.

More recently, in Carpenter v. United States (2018), the Court limited that principle, holding that individuals retain a reasonable expectation of privacy in historical cell-site location data, even when held by third parties.

The Federalist Society’s Practice Group members are grouped by substantive area of law. Every Practice Group has an Executive Committee that meets once a month. These volunteers help track major developments in their area of expertise and direct the content and programming of the Practice Group. They organize events including FedSoc Forums, in person programs, and panels for several single day conferences like the annual Executive Branch Review Conference. Executive Committee members regularly author blog posts and articles featured in FedSoc’s Publications. They also help plan and present FedSoc’s flagship annual conference, the National Lawyers Convention.
