Pennsylvania prosecutors asked the U.S. Supreme Court on Monday to overturn a ruling that reversed Bill Cosby’s conviction for sexual assault. 

Cosby had served more than two years of a 10-year sentence when the state’s highest court tossed the conviction in June, saying it agreed with former prosecutor Bruce Castor that a promise from his office prevented Cosby from being charged in the case.

Montgomery County prosecutors argued that such a ruling could set a dangerous precedent if convictions are overturned due to closed-door deals. 

“This decision as it stands will have far-reaching negative consequences beyond Montgomery County and Pennsylvania. The U.S. Supreme Court can right what we believe is a grievous wrong,” Montgomery County District Attorney Kevin Steele wrote in the petition, which seeks a Supreme Court review under the Due Process clause of the U.S. Constitution.

Cosby’s lawyers have long argued that he relied on a promise that he would never be charged when he gave damaging testimony in an accuser’s civil suit in 2006.

The admissions were later used against him in two criminal trials.
