Bill Cosby (111878)

(CNN) — A court granted a motion Monday allowing for Bill Cosby and his former attorney to be deposed as part of a defamation lawsuit filed by model Janice Dickinson.

Dickinson is one of dozens of women who have publicly accused Cosby of sexual misconduct over several decades. The comedian has said that Dickinson fabricated her story. He has not been charged and has vehemently denied wrongdoing.

“In her complaint, Ms. Dickinson alleges that Mr. Cosby defamed her when he called her a liar after she publicly disclosed that Mr. Cosby had drugged and raped her in or about 1982. Ms. Dickinson is proud to stand with the more than 50 women who have accused Mr. Cosby of attempted or actual sexual assault,” said Dickinson’s attorney, Lisa Bloom.

Los Angeles Superior Court Judge Debre Katz Weintraub ordered that the depositions of Cosby and his former attorney Martin Singer take place by November 25, according to Bloom.

An attorney for Cosby, 78, released a statement saying that their side plans to appeal.

“The Court’s unfortunate but not surprising ruling permitting a limited deposition of Mr. Cosby regarding the statements of his former attorney Martin Singer was legally incorrect and deprives Mr. Cosby of a right well-settled under California law to have his motion to strike heard before unnecessary, expensive and burdensome discovery. It is disturbing that Mr. Cosby is not receiving the same protections as every other defense litigant in California,” said Monique Pressley.

In a separate matter, Cosby was deposed last month in Boston, Massachusetts, about his alleged serial doping and groping of young women.

In a 2005 sworn deposition in a different civil case, Cosby admitted to getting prescription Quaaludes to give to women he wanted to have sex with. The contents of that sealed deposition only recently came to light.
