Bill Cosby is due back in a Pennsylvania court again today to appeal his sexual assault conviction.
Cosby was first charged in June of 2017 with felony sexual-assault that occurred in 2004 but this time, the appellate court is focused on the alleged trial errors that Cosby's legal team says happened.
One includes the promise Cosby had from a former prosecutor that he would never be charged in the case.
This promise led the former-comedian to give a deposition that was later used against him when the documents became unsealed.
Cosby, who is now 82-years-old, still sits in jail serving a three to ten year sentence.
