Kristina Ruehli gave an interview with Philadelphia Magazine last year (14) in which she claimed The Cosby Show star drugged and raped her in his California home in 1965 when she was 22 years old.

Cosby's then-attorney Marty Singer slammed Ruehli's allegations at the time, saying "Over and over again, we have refuted these new unsubstantiated stories with documentary evidence, only to have a new uncorroborated story crop up out of the woodwork. When will it end?"

On Monday (09Nov15), Ruehli lodged papers in a U.S. District Court in Springfield, Massachusetts in response to Singer's statement, contending that he and the comedian defamed her.

"In the false and defamatory November 21 Statement, Mr. Cosby's agent, Mr. Singer, stated explicitly, stated in effect, stated by innuendo and/or implied that Ms. Ruehli was a liar, that her story had not been and could not be corroborated as verified because it was untrue, and that she and her story were fantastical, ridiculous and absurd," Ruehli's attorney stated in the lawsuit obtained by

"It is one thing for an accused sexual assailant to remain silent and allow the legal process, or public opinion, to run its course, but it is quite another for him to unleash his agents to deny that he attacked the plaintiff and other women, to invite others to republish his statements, and to brand them as unreliable liars."

Ruehli is seeking an unspecified amount in damages.

In the past year, more than 50 women have come forward with decades-old accusations of sexual assault claims against Cosby. The statute of limitations has expired in almost all of the cases, preventing the alleged victims from pursuing criminal charges, and Cosby, who maintains his innocence, has never been charged with any offence.
