NCLA Challenges Geofencing Warrants at Supreme Court, Citing Fourth Amendment Violations

  • NCLA filed an amicus brief on March 2, 2026, urging the Supreme Court to rule geofencing warrants violate the Fourth Amendment.
  • The case, Chatrie v. United States, challenges a geofence warrant that captured Okello Chatrie’s location history without probable cause.
  • NCLA argues geofence warrants resemble colonial-era 'general warrants,' defying Fourth Amendment requirements.
  • The Fourth Circuit ruled that two hours of location history did not violate Carpenter v. United States, but NCLA disputes this interpretation.

The case highlights the tension between law enforcement’s use of advanced surveillance technology and constitutional privacy rights. If the Supreme Court rules in favor of NCLA, it could significantly limit the government’s ability to collect location data without probable cause, reshaping digital privacy standards. The outcome may also influence broader debates over surveillance and individual freedoms in the digital age.
