Facebook says it's found the 'smoking gun' that proves Paul Ceglia faked the document he says proves he owns a majority of the company.
He claims to own 84 percent of Facebook on the basis of a 2003 contract giving him half the company plus one percent for every day Facebook failed to launch after January 1 2004.
Last month, Magistrate Judge Leslie Foschio in Buffalo, New York, ordered Ceglia to hand over his computers, hard drives and electronic storage media for forensic tests, along with both the contract and the email he says demonstrate his ownership.
But, says Facebook in its filing last week, "Defendants have uncovered smoking-gun evidence that the purported contract at the heart of this case is a fabrication."
"[Ceglia] does not want the public to know what was discovered on his computers,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."
Facebook lawyers say they already had pretty strong circomstantial evidence that the contract was a fake, including inconsistent margin and font sizes.
It now appears that they've got something a bit more substantial to add - possibly the original contract on which it claims Ceglia's version is based. Facebook founder Mark Zuckerberg has always conceded that he did once sign a contract with Ceglia, just not one that related to Facebook.
Facebook says it wants this new evidence to be made public; it's currently designated as 'confidential'.
There'll be another hearing on August 17.
