With a potential fraud conviction in his future, Paul Ceglia is digging into the past to fight criminal charges that he fabricated a contract and other evidence in his failed suit claiming to own a 50 percent of Facebook Inc.

Ceglia, who’s facing a November jury trial in the government’s case, is seeking volumes of evidence that Facebook surely doesn’t want to produce, including many of Mark Zuckerberg’s emails from his undergrad years. According to a brief filed on Monday by the U.S. attorney’s office in Manhattan, Ceglia has asked the court to issue subpoenas to both Facebook and Harvard University for electronic and hard copy records. Ceglia wants to see the contents of Zuckerberg’s email accounts, hard drives and cellphones from 2003 and 2004, when the soon-to-be billionaire was launching Facebook from his Harvard dorm room. He’s also seeking academic disciplinary records and bank records for all of Zuckerberg’s accounts during that time.
