Wesley Snipes is calling for a mistrial in his tax evasion investigation.

The 'Demolition Man' star - who was handed a three-year sentence by US courts in April 2008 after he was found to have "wilfully neglected" to file his income tax return - insists his trial wasn't fair because some jurors were prejudiced against him.

He has already been granted numerous postponements in starting his sentence, which was most recently due to begin on September 2.

In documents filed to a Florida court on Monday (23.08.10), Wesley claims his defence team received emails after the trial from two jurors who claimed three others "told us Snipes was guilty before they even heard the first piece of evidence."

The 48-year-old actor believes this evidence should be enough to have a mistrial declared, but also further claims the US government didn't disclose charges brought before his former accountant and a key witness against him, Kenneth Starr.

Kenneth was already under investigation for engaging in "criminal activities of conspiring to evade income taxes" with another client at the time of the actor's trial.

A new date for Snipes' incarceration will only be set after several pending motions in the case have been ruled on.
