Overview
- The Supreme Court ruled Monday, June 29, 2026, that law enforcement’s multi‑step use of geofence warrants to obtain phone location history qualifies as a Fourth Amendment search in a 6–3 decision.
- The Court did not ban geofence warrants but remanded Okello Chatrie’s conviction to the 4th Circuit so that judges can decide whether the specific warrant met the Constitution’s particularity and probable cause requirements.
- In the case record, investigators used a three‑step geofence process that began with anonymized device lists, narrowed to movement data for a smaller set, and ended with subscriber identities that led to searches that found cash, a gun, and demand notes.
- The ruling tightens judicial oversight of place‑based digital sweeps and reduces the reach of the old third‑party doctrine for precise, high‑frequency location records, while tech practices and company responses create uneven effects on investigations.
- Practically, Google has largely stopped responding to Location History geofence requests after storage changes, other firms still receive such warrants, and lower courts plus state laws like California’s will shape how and when police can use geofence searches next.
