In a sweeping endorsement for privacy, the Supreme Court ruled that authorities must have a warrant to search personal mobile devices- such as cellphones.
By a vote of 9-to-0, justices ruled these devices do not fall into the same category as wallets, briefcases, and vehicles.
Generally, such searches are legal if there is "probable cause" a crime has been committed.
The case stems from two cases in which the suspects’ conviction was based on information found during an initial search of mobile devices.
The ruling -- which is a blow for law enforcement -- could set a new standard privacy cases in the future.
