Hours of arguments were heard by the New Jersey Supreme Court on whether a criminal defendant can be compelled to provide passcodes to his locked cellphones and whether such action is considered a form of self-incrimination that can be used against him.

In State v. Andrews, the justices must decide whether to uphold the Appellate Division’s ruling that law enforcement officers acted within legal bounds when they confiscated and retained Robert Andrews’ cellphones and required him to provide passcode information that would allow access to the content of the phones.
