Facebook is asking a federal court to dismiss a lawsuit from Paul Ceglia, which claims that he is entitled to 50% of Mark Zuckerberg’s ownership in Facebook. Ceglia cites a contract that he had with Mark Zuckerberg from 2003.

Paul Ceglia is currently in the middle of a lawsuit against Facebook Inc. and Mark Zuckerberg. Ceglia claims to own half of Mark Zuckerberg’s equity in Facebook. The latest about Ceglia is that he has asked a judge to sanction Zuckerberg for allegedly destroying e-mail messages that are related to their dispute.

Paul Ceglia is best known for filing a lawsuit against Facebook and Mark Zuckerberg.  Ceglia said he had a document that shows that Zuckerberg promised him equity in Facebook that would be worth over half of the company.  Interestingly Paul Ceglia has decided to contact the Winklevoss twins via Twitter.

Paul Ceglia, the man that claims to own over half of Facebook, has told his lawyers not to comply with a court order to turn in e-mail data. Facebook had asked U.S. Magistrate Judge Leslie Foschio in Buffalo, New York to request Paul Ceglia and his lawyers to turn over e-mail accounts and passwords.

Paul Ceglia is a man that used to live in New York, but now lives in Ireland that filed a lawsuit against Facebook. The lawsuit claims that Ceglia has a contract with Facebook CEO Mark Zuckerberg from 2003 that entitled him to half or more in equity of the large social networking company. Zuckerberg claimed that the real contract was for computer consultant work on Ceglia’s “StreetFax” project and didn’t have anything to do with Facebook.

Social network company Facebook said that they have the “smoking gun” evidence they need that proves Paul Ceglia faked the document that claims he has a major equity ownership in the company. Ceglia claims that he owns 84% of Facebook based on a 2003 contract that he made with Facebook co-founder and CEO Mark Zuckerberg.

As a refresher, Paul Ceglia is a man in New York that is claiming to own at least 50% of Facebook. Ceglia claims that he hired Facebook CEO Mark Zuckerberg for some freelance work several years ago through a Craigslist post.

Facebook recently filed for an expedited discovery in lawsuit with Paul Ceglia. Paul Ceglia claims to be entitled to a significant amount of equity in Facebook. He claims to have signed a contract with Mark Zuckerberg back in 2003. When the news about this broke, people laughed until it was revealed that law firm DLA Piper was backing him up.
