United States v. Wurie
The flip-phone case consolidated with Riley v. California, producing the Supreme Court’s warrant requirement for searches of digital information on phones seized incident to arrest.
Executive Summary
Wurie shows that the warrant rule is not limited to smartphones or extensive forensic extractions. Even a brief manual review of call information on a basic phone is a search of digital data.
After arresting Brima Wurie for a drug offense, officers saw repeated incoming calls on his flip phone from a contact labeled “my house.” They accessed the call log, obtained the associated phone number, traced it to an address, and used what they found to help secure a search warrant for the residence. The First Circuit held that the warrantless phone search violated the Fourth Amendment. The Supreme Court reviewed Wurie together with Riley v. California and unanimously held that officers ordinarily must obtain a warrant before searching digital information on a seized cellphone.
Facts
Boston police officers observed what they believed was a drug transaction and arrested Wurie. At the station, officers seized cash, two cellphones, and keys.
One phone repeatedly received calls from a number displayed as “my house.” Officers opened the phone, accessed the call log, obtained the number, used an online directory to identify an address, and observed a woman resembling the phone’s wallpaper at that location.
Officers obtained a warrant for the apartment and found drugs, firearms, ammunition, and cash. Wurie moved to suppress the evidence as fruit of the phone search.
Procedural History
The district court denied suppression and Wurie was convicted. The First Circuit reversed in relevant part, holding that the search-incident doctrine did not justify searching the phone’s digital contents. The Supreme Court granted review, consolidated the matter with Riley v. California, and affirmed the First Circuit’s judgment.
Constitutional Question
May police search digital information on a cellphone seized from an arrestee without a warrant under the search-incident-to-arrest doctrine?
Holding
Ordinarily, no. Officers may seize and secure the device, but must generally obtain a warrant before accessing call logs, contacts, messages, images, applications, or other digital contents. Case-specific exigent circumstances remain available.
Court’s Reasoning
Digital data cannot itself be used as a weapon, so officer-safety concerns ordinarily justify control of the physical device rather than examination of its contents.
Once the device is secured, the arrestee cannot directly delete evidence. Concerns about remote wiping or encryption do not create a categorical exception for every phone.
The quantity and quality of information stored on even ordinary phones can reveal private associations, communications, locations, and activities. The search-incident doctrine did not justify that intrusion.
What the Decision Does Not Hold
- The rule does not prohibit seizure of a phone incident to arrest or reasonable preservation measures while officers seek legal process.
- It does not foreclose a warrantless search supported by a genuine, documented exigency, valid consent, or another recognized exception.
- It does not answer every question about biometric unlocking, border searches, probation conditions, provider-held records, or cloud accounts.
Agency Guidance
Agency policy and training should translate the decision into specific, reviewable procedures:
