CINCINNATI -- A former Cincinnati Bengals cheerleader should not have been allowed to sue an Arizona-based gossip website over online posts about her sexual history, an appeals court ruled Monday in a case watched closely by Internet giants including Google and Facebook.

The ruling from the Cincinnati-based 6th U.S. Circuit Court of Appeals reverses a Kentucky federal judge's decision that allowed the cheerleader's lawsuit to proceed and further strengthens broad immunities enjoyed by Internet providers for content posted by third parties.

Former Bengals cheerleader Sarah Jones sued thedirty.com and its owner, Nik Richie, over graphic posts about her and her ex-husband's sexual history. Jones said the posts were untrue and caused her severe mental anguish and embarrassment.

In July, federal Judge William Bertelsman rejected arguments from Richie's attorneys that the publisher should be immune from lawsuit. A jury later found the posts about Jones were substantially false and Richie had acted with malice or reckless disregard by publishing them. The jury awarded Jones $338,000.

In Monday's ruling, a three-judge appeals panel said Bertelsman should have granted Richie immunity, citing the federal Communications Decency Act, a 1996 law that gives websites immunity from liability for content posted by users.

Judges and courts across the country have upheld the law hundreds of times.

The 6th Circuit's decision reverses Bertelsman's ruling and means Jones does not get the $338,000 award.

"I feel like one of those lawyers who has a client that just got out of death row from DNA and he's been sitting there for 20 years and we find out he was innocent all along," said Richie's attorney, David Gingras, from his office in Scottsdale, Arizona. "You're happy that he's out of jail, but you're really not happy it took so long to get there."

Jones' Cincinnati attorney, Chris Roach, said he is planning to ask the U.S. Supreme Court to review the case.

"(Richie) is using those basic editorial functions and the Communications Decency Act to get people to submit defamatory material so he can post it," Roach said. "That just doesn't go with the spirit of the law."

Richie's website allows users to submit anonymous posts about anyone from the girl next door to professional athletes and politicians, often accusing them of promiscuity, criticizing their plastic surgery or picking apart their looks.
