Explainer: Bill Cosby's conviction overturned

Bill Cosby's sexual assault conviction was thrown out Wednesday by Pennsylvania's highest court in a ruling that swiftly freed the actor from prison more than three years after he was found guilty of drugging and molesting Temple University employee Andrea Constand at his suburban Philadelphia mansion.

Cosby, 83, was the first celebrity tried and convicted in the #MeToo era, and his conviction was seen as a turning point in the movement to hold powerful men accountable for sexual misconduct.

The split court found that Cosby was unfairly prosecuted because the previous district attorney had promised the comedian once known as “America's Dad” that he wouldn't be charged over Constand's accusations. Cosby was charged by another prosecutor who claimed he wasn't bound by that agreement.

The court said that's not the case. The justices found that Cosby relied on that promise when he agreed to testify without invoking his Fifth Amendment right against self-incrimination in a lawsuit brought against him by Constand.

The court concluded that prosecutor who later brought the charges was obligated to stick to the nonprosecution agreement, so the conviction cannot stand.

The justices wrote that “denying the defendant the benefit of that decision is an affront to fundamental fairness, particularly when it results in a criminal prosecution that was foregone for more than a decade.”

The promise not to prosecute Cosby was made in 2005 by Bruce Castor, who was then the top prosecutor for Montgomery County. Castor was also on the legal team that defended former President Donald Trump during his historic second impeachment trial over the Jan. 6 insurrection at the U.S. Capitol by his supporters.
