(Reuters) – A federal judge dismissed a lawsuit filed by New York businessman Paul Ceglia against Facebook Inc and its founder Mark Zuckerberg, adopting findings by a magistrate judge that a purported contract entitling him to an ownership stake in the company was fake, according to court documents. Ceglias 2010 lawsuit against Facebook and Zuckerberg underlay a subsequent federal prosecution in Manhattan, in which Ceglia was accused of forging a 2003 contract with Zuckerberg that supposedly entitled him to a part-ownership interest in the social networking company. Facebook argued that the only contract between the two men was related to Ceglias company, StreetFax.com, and accused Ceglia of faking various documents as part of his lawsuit.
