In a unanimous decision, the United States Supreme Court has held that law enforcement may not generally search for electronic data on a cellphone without a warrant. Specifically, the Court, in an opinion written by Roberts in which all but Justice Alito joined (Alito filed an opinion that concurred in part and concurred in the judgment), held that generally law enforcement may not search a cellphone seized incident to a lawful arrest without a warrant.
