But outside, several protesters were vocal about Cosby's guilt and their support of Constand, who will take the stand once again this month to testify that Cosby allegedly sexually assaulted her in 2004. Constand's lawyer has said the co-worker is lying. She was tackled to the ground and charged with disorderly conduct, if convicted she'll be fined and will pay court fees.
His retrial is now the most high-profile criminal case so far in a #MeToo world, the United States cultural watershed that has ruined the careers of a string of powerful men in Hollywood, politics and the media.
Bill Cosby's sexual assault retrial likely won't be anything like his first one.
The payment had never been disclosed before publicly, but Cosby, 80, agreed to reveal it during the pretrial discussions.
Defence attorneys were due to make their opening statement on Tuesday. "We believe this woman who is talking and telling her truth, and I want her to be raised to always have a voice and to know that I believe her when she tells me anything that happens". This time, Cosby has lifted his objections, and jurors can hear more about the lawsuit, including the payment amount.
The protester was topless and had the names of Cosby's accusers as well as the phrase "Women's Lives Matter" written in black and red on her body.
Cosby, who has said the sex with Constand was consensual, was greeted by a handful of supporters, who shouted encouragement to him.
His is the first high-profile sexual assault trial of the MeToo era, and experts are watching to see what effect the of harassment and assault against prominent men may have on the trial and on jurors' attitudes toward sexual assault.
According to reports, Judge Steven O'Neill is questioning the juror over the alleged comment and it is unclear when the trial will resume.
