Technology Privacy Surveillance

Riley

573 U.S. 373Supreme Court of the United States2014Date unavailable

Summary

Riley v. California, 573 U.S. 373 (2014), held that the Fourth Amendment generally requires police to get a warrant before searching digital information on a cell phone seized incident to arrest. The Court balanced law enforcement needs against the uniquely broad privacy interests in modern phones and left room for exigent circumstances in urgent cases.

Legal Issue

Does the search-incident-to-arrest exception allow police to search digital information on a cell phone seized from an arrested person without first getting a warrant?

Holding

No. Police generally may not search digital information on a cell phone seized from an arrested person without a warrant. Officers may secure the phone and inspect its physical aspects for safety, and exigent circumstances may justify immediate action in a particular case.

Rule of Law

Police can take and secure a phone during an arrest, but they usually need a warrant before searching what is inside it.
