People surfing the Internet on their own computers have a reasonable expectation of privacy, and a grand jury subpoena is needed for law enforcement to obtain identifying information, the New Jersey Supreme Court ruled on Monday in a case of first impression.

The Court found the right of privacy in Internet-service-provider records is inherent in the New Jersey Constitution, the same source that the Court has found to protect telephone and banking records, even absent comparable protections in the U.S. Constitution or federal case law.
