A trio of Pennsylvania judges on Monday appeared deeply skeptical of Bill Cosby's effort to have his sexual assault conviction overturned.
The comedian's lawyers argued in court that the trial judge had deprived him of a fair trial.
Cosby, known for his role as the lovable father in the 1980s television series The Cosby Show, saw his family-friendly reputation shattered after dozens of women accused him of sexual assault over decades.
He became the first celebrity to be convicted in the #MeToo era when a jury found him guilty in April 2018 of drugging and sexually assaulting Andrea Constand at his home in 2004.
The 82 year old, who is serving a prison sentence of three-to-10 years, did not attend Monday's hearing.
The appeal focused on the decision by Montgomery County Judge Steven O'Neill to allow five accusers to testify at trial that Cosby had drugged and sexually assaulted them years previously, just as Constand claimed he had done.
Cosby's lawyers argued that the women's stories were too dissimilar to be permitted as pattern evidence and essentially guaranteed the jury would view him as guilty.
