Prosecutors announced immediately that they would retry the case, leading to the prospect of the now frail and disgraced comedian, once adored by millions as "America's Dad", could yet return to court. All told, if found guilty, Cosby could spend the rest of his life in prison.
Lawyer Brian McMonagle told jurors that while Cosby had been unfaithful to his wife, he did not commit a crime. "We will get to do it again." said Dolores Roiani, Constand's lawyer.
Lowe, interviewed on Temple's main campus in North Philadelphia, said he welcomed a new trial as a way to provide a definitive statement about Cosby's guilt or innocence.
O'Neill said: "I remind everyone that this is not vindication or victory".
The Associated Press does not typically identify people who say they are victims of sexual assault unless they grant permission, which Constand has done.
When asked about Cosby's statement during a press conference, Montgomery County, PA District Attorney Kevin Steele responded, "I'm not going to talk about Camille Cosby". "If you do, you're saying if someone is wealthy or famous, they don't deserve the same sort of justice as everybody else".
She said she hopes more accusers can testify "because that's relevant on the issue of whether Mr. Cosby had a plan, a scheme, to drug and sexually assault women". This particular case was for his alleged sexual assault against Andrea Constand.
Yes. If he had been convicted, prosecutors say Cosby would have had to register as a sex offender and face an assessment to determine whether he was a sexually violent predator.
Cosby was charged with three counts of aggravated indecent assault. Constand says Cosby gave her pills that made her woozy, then violated her. "Overtly arrogant, collaborating with the district attorney", said her statement, which was tweeted by her husband and read by an associate of the public relations firm representing Cosby.
He did not take the stand in his own defense, leaving it to his attorney to argue Cosby and Constand were lovers sharing a consensual sexual encounter.
In civil lawsuits in the United States, plaintiffs need only show that the weight of evidence is on their side, meaning they have information to tip the scales above 50% in their favour, as opposed to criminal cases in which prosecutors must prove claims beyond a reasonable doubt.
Constand, 44, of Ontario, Canada, testified over two days that after taking the blue pills she began slurring her words and became "frozen" or paralyzed and was unable to fight off Cosby's sexual advances.
Cosby's wife, Camille, joined him in the courtroom as his defense team presented its case.
Cosby himself didn't comment, remaining stoic as the judge declared a mistrial, but Wyatt declared the star's "power is back".
Jury deliberations started Monday afternoon. The jury, which consisted of seven men and five women, failed to reach a verdict after 52 hours.
But O'Neill gave them a special instruction required by law and sent them back to deliberate to see if they could settle their differences and reach a verdict.
