Constand sued Castor three years ago, arguing that comments he made to explain his decision not to prosecute Cosby had hurt her reputation by depicting her as a liar.
The terms of the settlement were not disclosed. The case had been scheduled for trial in April at the U.S. District Court for the Eastern District of Pennsylvania.
“All litigation between the parties has been resolved to the mutual satisfaction of both parties,” the lawyers for both sides said in a joint statement sent Friday. “Other than what is contained in this statement, neither side will have any further comment.”
Castor was the Montgomery County district attorney in 2005 when Constand approached authorities to complain that Cosby had sexually assaulted her at his home outside Philadelphia. Castor declined to bring charges, saying he found “insufficient credible and admissible evidence” and that both sides could be portrayed in “a less than flattering light.”
Constand then sued Cosby and won a civil settlement in 2006.
Constand’s defamation lawsuit referred to comments that Castor made later, in 2015, after a number of other women had come forward to accuse Cosby of drugging and sexual assaulting them. Castor was asked then about his decision not to prosecute, and he offered answers that Constand said suggested she had been inconsistent in describing the assault and had provided a more detailed account in the Cosby civil suit.
“If the allegations in the civil complaint were contained in that detail in her statement to the police, we might have been able to make a case out of it,” Castor told The Associated Press. In a tweet, he said the account she had given the police was “much different than she told court in her lawsuit,” according to the filing.
Castor’s successors as prosecutors for Montgomery County decided later in 2015 to bring charges against Cosby, in part because of new evidence. Cosby was convicted last year of aggravated indecent assault and is serving a sentence of three to 10 years in prison.
Castor had argued that his comments were true and so they could not be a basis for a defamation suit.
The order, by Judge Eduardo C. Robreno, announcing the settlement and dismissing the case was filed in court Monday.
