The state Supreme Court on Tuesday gave workers in New Jersey an assurance of privacy in using workplace computers to talk with their lawyers, ruling a company’s e-mail-monitoring policy yields to the attorney-client privilege.

Chief Justice Stuart Rabner, writing for the unanimous Court in Stengart v. Loving Care Agency Inc., A-16-09, said a plaintiff in an employment discrimination suit against her employer had a reasonable expectation that e-mails to and from her attorney on her personal Yahoo account would be private, although transmitted via a company-owned laptop.
