Idaho v. Karst
Annotate this CaseDefendant-appellant Desiree Karst appealed a district court’s partial denial of her motion to suppress evidence obtained during a traffic stop. Karst argued on appeal that the police sergeant impermissibly extended the traffic stop when he briefly interrupted his traffic-related investigation to contact dispatch and request a drug-dog unit at the scene. The Court of Appeals affirmed the district court’s decision, citing its recent decision in Idaho v. Still, 458 P.3d 220 (Ct. App. 2019). The Idaho Supreme Court granted Karst’s petition for review, overruled Still, reversed the district court’s decision, and remanded for further proceedings. The Supreme Court found that an unlawful extension of a traffic stop occurs when an officer’s detour prolongs, or adds time to, the original purpose for the stop. The Court of Appeals’ decision in Still improperly required “abandonment” of the traffic mission for a stop to become unlawfully extended. Here, the Court found the arresting sergeant indeed impermissibly extended the duration of the traffic stop when he requested the drug- dog unit, in violation of the Fourth Amendment.
