In a brief filed Tuesday afternoon, the coalition says a search warrant signed by a judge is necessary before the FBI or other police agencies can read the contents of Yahoo Mail messages--a position that puts those companies directly at odds with the Obama administration.
Yahoo has been quietly fighting prosecutors' requests in front of a federal judge in Colorado, with many documents filed under seal. Tuesday's brief from Google and the other groups aims to buttress Yahoo's position by saying users who store their e-mail in the cloud enjoy a reasonable expectation of privacy that is protected by the U.S. Constitution.
"Society expects and relies on the privacy of e-mail messages just as it relies on the privacy of the telephone system," the friend-of-the-court brief says. "Indeed, the largest e-mail services are popular precisely because they offer users huge amounts of computer disk space in the Internet 'cloud' within which users can warehouse their e-mails for perpetual storage."
