Bill Cosby may be out of prison before the end of 2020. The imprisoned actor will get the chance to fight his 2018 sexual assault conviction. The Pennsylvania Supreme Court agreed on Tuesday to review two aspects of the case the comedian’s lawyers challenged on appeal. Cosby, now 82 years old, has spent nearly two years behind bars for allegedly drugging and sexually assaulting Andrea Constand in 2004. He was sentenced to three to 10 years in state prison.So why is he so likely to be released? Well, because his conviction was fraudulent.The Supreme Court will review Cosby’s assertion that he had a deal with a former Montgomery County District Attorney that he’d never be charged in the case. Here’s what happened. Bill Cosby was sued by the alleged accuser, and she asked him to take a deposition. Bill and his legal team refused the deposition, claiming Fifth Amendment protection.The District Attorney stepped in, and promised that no matter what Bill said in the deposition, he would never be prosecuted over what he said.Bill and his team then were forced by a judge to answer questions in a deposition in the civil lawsuit.Shortly after his testimony, a new District Attorney charged Bill with sexual assault. He tore upon the deal, and charged Bill. Now a court will examine that District attorney’s actions.Cosby claims an agreement was reached so he would testify in the trial accuser’s civil lawsuit, which was allowed at trial. His lawyers argue that by relying on that agreement, Cosby’s constitutional rights against self-incrimination were forfeited and later used against him .
