The Supreme Court of Ohio ruled last month in State v. Smith that the warrantless search of a cell phone seized incident to a lawful arrest is prohibited by the Fourth Amendment. The court refused to extend to cell phones the normal doctrine allowing police to search an arrestee’s person and containers found on or near him without obtaining a search warrant, holding that a cell phone is not a “closed container” because it does not hold other “physical objects.” The court also found that cell phones’ “ability to store large amounts of private data gives their users a reasonable and justifiable expectation of a higher level of privacy in the information they contain,” and that police therefore must “obtain a warrant before intruding into the phone’s contents.”
