Police may search unarrested passenger’s belongings found 
outside car
Jan. 8, 2009 – Police may search the belongings of a passenger 
who has not been arrested and that are outside of the automobile 
searched, the Wisconsin Supreme Court held Dec. 30 in State 
v. Denk, 2008 WI 130.
The court reasoned that such a warrantless search is consistent with 
the historical rationales of protecting the police officer and 
preserving evidence.
In this case, Jordan A. Denk was a passenger in a car parked at night 
alongside a county road. When a police officer stopped to see if the 
motorists needed assistance, he ran a license plate check to discover 
the plates did not match the car. The officer approached the car a 
second time to talk to the occupants and smelled marijuana.
After receiving consent to search the car, the officer ordered the 
driver and Denk out of the vehicle. The officer noticed the 
driver’s sweatshirt pocket was bulging, but the driver refused to 
allow the officer to perform a protective pat down. The officer directed 
the driver to empty his pockets whereupon the officer spotted drug 
paraphernalia. The officer arrested the driver and completed a search 
uncovering more contraband.  
Turning to Denk, the officer noticed an eyeglass case lying on the 
ground next to the passenger door. Denk acknowledged that it belonged to 
him. The officer asked Denk to retrieve the case and he did so, placing 
it on the hood of the car. The officer opened the case and found drug 
paraphernalia. The officer handcuffed Denk and searched him, finding 
marijuana and methamphetamine.
The supreme court affirmed the circuit court order upholding the 
search, citing State 
v. Pallone, 2000 WI 77. In Pallone, a 
passenger’s belongings can be searched incident to the arrest of 
the driver when the passenger poses as much danger as the arrested 
driver.  In this case, the court found that the eyeglass case was 
within easy reach of Denk who had not been restrained by the lone 
officer. The case could have contained a weapon or evidence Denk might 
seek to discard.
Denk failed to persuade that a court should first determine whether 
the unarrested passenger’s belongings seized outside the car had 
originally been loose within the vehicle compartment (where it would 
have been subject to a search) or if it had been on the 
passenger’s person (where it would not). The court said the 
circumstances of how an item came to rest outside the vehicle does not 
address the concerns of protecting the officer or preserving 
evidence.   
However, the court reaffirmed that unarrested passengers cannot 
themselves be searched based solely on the arrest of the driver. In 
order to search the body of a passenger, the arresting officer must have 
individualized cause.
