People v. Berdahl, 2019 CO 29

Early morning, Berdahl was found walking near a disabled truck in freezing weather; officers offered a courtesy ride to warm up/reach a gas station.
A Colorado State Patrol sergeant told Berdahl he would perform a quick pat-down for weapons before allowing him into the patrol car; Berdahl immediately positioned himself and submitted to the frisk.
During the frisk the sergeant felt a cylindrical object in a sock on Berdahl’s ankle and recovered a methamphetamine pipe and a small blue bag with suspected meth, leading to Berdahl’s arrest for possession and paraphernalia.
At suppression hearing, the trial court found the pat-down was not consensual but nonetheless reasonable for officer safety; the court later found consent voluntary on remand under People v. Magallanes-Aragon.
A Colorado Court of Appeals panel disagreed, holding the sergeant’s statement was a claim of lawful authority and Berdahl’s submission was mere acquiescence, requiring suppression; the Supreme Court granted certiorari.
The Colorado Supreme Court reversed the court of appeals, holding Berdahl voluntarily consented to the limited pat-down under the totality of the circumstances and the search was constitutional.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether an officer may condition a courtesy ride on a pat-down and lawfully conduct a frisk when the person submits	People: The pat-down was voluntary or reasonable for officer safety; the frisk was lawful and any consent was valid	Berdahl: The officer’s statement was an assertion of authority; his submission was acquiescence, not voluntary consent	Held: Submission to the pat-down, after the offer of a ride and immediate compliance, constituted voluntary consent; search constitutional
Whether Berdahl’s conduct evidenced voluntary consent under objective totality-of-circumstances test	People: Objective factors (officers’ conduct, briefness, context) show no coercion and support inference of consent	Berdahl: His perception of having no choice (weather, stranded) rendered consent involuntary due to implied coercion	Held: Court found no overbearing police conduct; an objectively reasonable person would view the request as safety-related, not coercive; consent voluntary
