The Cosby Show star is facing a lawsuit in Massachusetts federal court from seven women, who his lawyers reportedly dismissed as liars after they went public with decades-old accusations of inappropriate behaviour, drugging and/or rape at the hands of the comic.

Camille Cosby, who previously served as her husband's business manager, was summoned to give evidence under oath in February (16), testifying for the first time about the multiple sex claims.

She was due to be quizzed by the plaintiffs' lawyer, Joseph Cammarata, for a second time last month (Mar16), but her lawyers were allowed more time to prepare for the case and subsequently filed a motion to terminate the deposition.

However, her request was recently denied and she has been ordered to sit for a second round of questioning on Monday (18Apr16), but the scope of what can be asked of her has been limited.

"While not agreeing to terminate the deposition, the court granted Mrs. Cosby's request to limit the types of questions she could be asked going forward, prohibiting plaintiffs from asking improper questions, questions seeking her opinion, and questions involving marital communications," a statement from her attorneys reads.

Cosby has been accused of rape, drugging, and performing inappropriate sex acts by over 50 women in the past 18 months.

He is currently seeking to suspend the proceedings in the defamation case to allow him to focus on criminal charges against him in Pennsylvania, where he stands accused of aggravated indecent assault. Cosby insists he is not guilty of allegedly drugging and sexually assaulting former Temple University employee Andrea Constand in his Pennsylvania home in 2004.

He was not charged at the time of the reported attack, but Cosby later settled a civil suit from Constand out of court. It was his leaked deposition in that case, in which he admitted to obtaining sedatives to give to women he wanted to sleep with, which prompted prosecutors to reevaluate the case last year (15), when his testimony was unsealed.

Cosby has also filed an appeal to have the criminal charges dismissed, claiming the former district attorney agreed not to prosecute him in exchange for his testimony in the civil case. His request was denied in February (16), but he is appealing to a higher court.
