A California judge ruled Thursday that Apple can force three Mac sites–Powerpage.org, AppleInsider and Think Secret–to disclose where they got confidential information about an unreleased Apple product. “Judge James Kleinberg of state court in San Jose, California, refused to shield the publishers from Apple’s inquiries,” reports Bloomberg. “Lawyers for the Electronic Frontier Foundation, a group that seeks to protect civil liberties related to technology, sought the order on behalf of the publishers. ‘We’re disappointed that the tentative ruling was a denial,’ said Kurt Opsahl, a lawyer for the foundation. He said he would appeal the ruling.” In December, Apple filed a suit seeking to force the three sites to turn over information about the person who leaked details on an unreleased product code named “Asteroid.”
