* Paul Ceglia sued Facebook, claiming ownership stake
* Facebook has “smoking gun” evidence of fraud-filing
* Facebook asks judge for permission to reveal evidence
SAN FRANCISCO, Aug 5 (Reuters) - Facebook says it has uncovered “smoking gun” evidence that a contract at the heart of a lawsuit against the company and its founder Mark Zuckerberg is fraudulent, according to a Facebook court filing.
New York state resident Paul Ceglia sued Facebook in July 2010, alleging that a contract he struck with Facebook co-founder Mark Zuckerberg in 2003 entitled him to half the company.
Facebook, the world’s No. 1 Internet social network with more than 500 million users, has said that Ceglia’s contract is a forgery and has characterized Ceglia as an “inveterate scam artist.”
In a court filing on Thursday, attorneys for Facebook said they had uncovered documents on Ceglia’s computers that undermine his claims. Facebook did not reveal the documents, but has asked a U.S. judge for permission to make them public.
“[Ceglia] does not want the public to know what was discovered on his computers,” attorneys for Facebook wrote, “because it includes smoking-gun documents that conclusively establish that he fabricated the purported contract and that this entire lawsuit is a fraud and a lie.”
An attorney for Ceglia did not immediately respond to a request for comment.
