Cosby was convicted of aggravated indecent assault in 2018 for drugging and sexually assaulting Andrea Constand in his Pennsylvania home in 2004. He was sentenced to three to 10 years in a state prison.
In a statement on behalf of Cosby and his family, publicist Andrew Wyatt praised the justices “for following the rules of law and protecting the Constitutional Rights of ALL American Citizens.”
“Mr. Cosby’s Constitutional Rights were a ‘reprehensible bait and switch’ by Kevin Steele, Judge Steve T. O’Neill and their cohorts,” Wyatt said. “This is truly a victory for Mr. Cosby but it shows that cheating will never get you far in life and the corruption that lies within Montgomery County District’s Attorney Office has been brought to the center stage of the world.”
The Montgomery County District Attorney’s office, which led the high-profile court case against Cosby, said in November that the main question of the appeal centered around the 14th Amendment and the right to due process.
As the decision stands now, it could have “far-reaching negative consequences” across the country, District Attorney Kevin Steele said in a statement.
The justices on Monday rejected the petition to take up the case without comment.
Jennifer Bonjean, a lawyer for Cosby, had urged the court not to step in.
“Under the unique facts of the case, the Pennsylvania Supreme Court concluded that [the former district attorney] had made an unconditional promise of non-prosecution, and that Cosby had relied on that promise to his detriment, namely foregoing his Fifth Amendment guarantees and testifying at four days of depositions, and that as a matter of fundamental fairness, the promise should be enforced,” she said.
