Three years after New York businessman Paul Ceglia first alleged that a contract with Mark Zuckerberg entitled him to a 50 percent ownership stake in Facebook, a judge has finally agreed with Gibson, Dunn & Crutcher that the case is a fraud.

Paul Ceglia—who claims that an old contract with Mark Zuckerberg entitles him to half of Facebook—has failed to have Facebook's counsel at Gibson Dunn disqualified because of a supposed conflict of interest. On Thursday a judge not only found the disqualification motion to be frivolous, but also indicated that he will impose sanctions on Ceglia's lawyer for filing it. Perhaps more importantly, the judge ordered Ceglia to produce a document that, according to Gibson Dunn, proves definitively that he's a fraud.
