From the AP:
The 11th U.S. Circuit Court of Appeals rejected the appeal by Snipes, who was convicted in 2008 on three misdemeanor counts of willful failure to file income tax returns.
His defense lawyers contended they received emails from former jurors reporting misconduct among other members of the panel. One of the former jurors said in the email that three other jurors acknowledged they had determined Snipes was guilty before the trial began.
A federal court rejected the request for a new trial and noted that there were reasons to question the veracity of the allegations made in the emails. The 11th Circuit upheld the ruling on Tuesday, finding that there wasn't "strong, substantial and incontrovertible evidence" that would warrant a new trial.
