Facebook founder Mark Zuckerberg says e-mails and a signed document that form the basis of a New York man’s lawsuit claiming part ownership of the social networking phenomenon are fakes.

Zuckerberg’s statements were included in papers filed June 2 by his attorneys in federal court in Buffalo. The attorneys want expedited access to the original materials, copies of which were filed with Paul Ceglia’s lawsuit, and to examine Ceglia’s computers and electronic media.
