Category: Expert Testimony
Robert du Purton was convicted of mail fraud and conspiracy to commit mail and wire fraud in 2001 for participating in an “elaborate scheme of fraudulent representations” in his rare coin business. According to trial evidence, du Purton lied to customers about the sources of coins, concocted phony auctions to drive up prices, and had his employees impersonate competitors or independent sources, among other things. His conviction was affirmed on direct appeal. Nearly fifteen years later, he brought a petition for writ of error coram nobis, claiming that the government presented false expert testimony at trial. In a per curiam decision, the Second Circuit (Katzman, Leval, Andrew Carter, District Judge) affirmed the denial of the petition.
