The Ohio Supreme Court has struck an important blow for privacy rights, ruling that the police need a warrant to search a cellphone. The court rightly recognized that cellphones today are a lot more than just telephones, that they hold a wealth of personal information and that the privacy interest in them is considerable. This was the first such ruling from a state supreme court. It is a model for other courts to follow.

Searches generally require warrants, but courts have carved out limited categories in which they are not needed. One of these is that police officers are allowed, when they arrest people, to search them and the area immediately surrounding them, as well as some kinds of containers in their possession.

When the police arrested Antwaun Smith on drug charges they seized his cellphone and searched it, examining his call records. The police did not have a warrant or the consent of Mr. Smith.

The Ohio Supreme Court ruled this month, by a 4-to-3 vote, that the search violated the Fourth Amendment’s protection against unreasonable search and seizure. Rather than seeing a cellphone as a simple closed container, the majority noted that modern cellphones — especially ones that permit Internet access — are “capable of storing a wealth of digitized information.”

This is information, the court said, for which people reasonably have a high expectation of privacy, and under established Fourth Amendment principles, police officers must get a search warrant before they can look through call logs or examine other data. The court wisely decided that it made no sense to try to distinguish among various kinds of cellphones based on what specific functions they have. All cellphones, the court said, fall under the search warrant requirement.

Few federal courts have considered the issue of cellphone searches, and they have disagreed about whether a warrant should be required. The Ohio ruling eloquently makes the case for why the very personal information that new forms of technology aggregate must be accorded a significant degree of privacy.

Good to hear. A little close however.
