The comedian, who was once affectionately known as “America’s Dad”, was found guilty of the attack in 2018.
Disgraced comedian Bill Cosby has won the right to fight his sexual assault conviction in a decision that could test the legal framework of #MeToo cases.
Cosby, 82, has been in a Philadelphia prison for nearly two years after he was convicted of drugging and sexually assaulting Andrea Constand in 2004.
He is serving a sentence of between three and 10 years after his conviction in 2018.
Pennsylvania Supreme Court has agreed to review two aspects of the case.
The first refers to the judge’s decision to let prosecutors call five other accusers to testify at the sexual assault trial, and whether the jury should have heard evidence Cosby gave the sedative Quaaludes to women.
Cosby’s lawyers have long complained the women’s testimonies were unreliable.
The court will also examine Cosby’s argument that he had an agreement with a former prosecutor that he would never be charged in the case.
Cosby says he relied on that agreement before agreeing to give evidence in Constand’s civil lawsuit.
The two aspects have been at the heart of the case since Cosby was charged in December 2015.
