A year ago, the Third Circuit in United States v. Katzin issued an opinion on GPS tracking, stating unequivocally and for the first time that a warrant is required before police can place a GPS tracking device on someone’s vehicle. Nine months ago, the Third Circuit agreed to rehear Katzin en banc. (We previously covered this case and discussed the uncertainty this rehearing created as to the warrant requirement.)

In contrast to the resounding endorsement of the warrant requirement by the panel, the en banc court focused on the good-faith exception to the exclusionary rule. The court ultimately allowed the GPS tracking data to be admitted at the trial even though it was obtained without a warrant.
