"The government may not compel a commercial ISP to turn over the contents of a subscriber's e-mails without first obtaining a warrant based on probable cause" (.pdf), the appeals court ruled. The decision—one stop short of the Supreme Court—covers Kentucky, Michigan, Ohio and Tennessee.


"I expect e-mail providers across the country will comply with this," he said in a telephone interview.



He appealed his 25-year conviction on those and other grounds, and the circuit court tossed his sentence on issues unrelated to the court's language concerning e-mail privacy.

At issue in Warshak's e-mail flap was a 1986 law that allows the government to obtain a suspect's e-mail from an internet service provider or webmail provider without a probable-cause warrant, once it's been stored for 180 days or more. The appeals court said Tuesday that this part of the Stored Communications Act is unconstitutional.


"The Fourth Amendment must keep pace with the inexorable march of technological progress, or its guarantees will wither and perish," the court ruled.

The Stored Communications Act was enacted at a time when e-mail generally wasn't stored on servers at all, but instead passed through them briefly on their way to the recipient's inbox. In today's reality, e-mail can, and is, being stored on servers forever. A consortium of businesses, including Google and Microsoft, recently asked Congress to update the law and require probable cause to obtain any e-mail.
