Dharun Ravi has filed papers to appeal his conviction on bias intimidation, invasion of privacy and other charges.

The papers indicate Ravi will appeal on grounds that the bias intimidation statute is unconstitutional as applied to Ravi. Also, Ravi contends that  several decisions by Superior Court Judge Glenn Berman,  "prejudiced the defendant's ability to get a fair trial,' reports the Star Ledger.

The appeal could take up to 2 years to decide after it is reviewed by a 3 judge panel.

Ravi was sentenced last month to 30 days in jail, community service and three years’ probation, and ordered to pay $10,000 toward a program to help victims of hate crimes.
