Reason: The Volokh Conspiracy, The Fifth Circuit Shuts Down Geofence Warrants—And Maybe A Lot More

Reason: The Volokh Conspiracy, The Fifth Circuit Shuts Down Geofence Warrants—And Maybe A Lot More by Orin S. Kerr:

An astonishing ruling, and one that creates splits on two differerent issues.

Once in a while there is a court ruling on the Fourth Amendment that just makes my jaw drop. The Fifth Circuit had such a ruling today, United States v. Jamarr Smith[, 2024 U.S. App. LEXIS 20149 (5th Cir. Aug. 9, 2024)]. The case creates a split with the Fourth Circuit on one important issue, and it creates another split with the Colorado Supreme Court on an even more important issue.

The new case is about the Fourth Amendment limits of geofence warrants, which are warrants to access location information for users who have opted into having Internet providers retain location history. The Fifth Circuit makes two important holdings. First, accessing any amount of geofence records is a search under an expansive reading of Carpenter v. United States. That’s the issue that creates the split with the Fourth Circuit in United States v. Chatrie. As I noted just a few weeks ago, Chatrie held that accessing such records is not a search in the first place, at least if the records sought are relatively limited in scale. The Fifth Circuit expressly disagrees.
