Cosby's Lawyers Ask For New Trial

Bill Cosby is fighting to get out of prison after three years inside.

Lawyers for Cosby appealed for a new sexual assault trial on Tuesday.

Cosby was convicted of drugging and sexually assaulting Andrea Constand during a 2004 encounter.

The lawyers claim the conviction was "fundamentally unfair." In the case the judge allowed Cosby's deposition from a civil lawsuit to be considered.

Lawyers for Cosby say he believed he had immunity from prosecution in the case when he gave the deposition.
