Google: No Expectation of Privacy in Gmail Emails

From Slate:

If you happen to be one of the 400 million people who use Google's Gmail service for sending and receiving emails, you shouldn't have any expectation of privacy, according to a court briefing obtained by the Consumer Watchdog website. In a motion filed last month by Google to have a class action complaint dismissed, Google's lawyers reference a 1979 ruling, holding that people who turn over information to third parties shouldn't expect that information to remain private.
