Bill Cosby's wife of 52 years is due on Tuesday to sit for a second day of questioning in Boston by lawyers for seven women who have accused the comedian of sexual assault and have sued him for defamation for denying their claims.


Camille Cosby's lawyers asked a federal magistrate judge last week to spare her a second day of questioning, saying an earlier deposition was mainly aimed at embarrassing her by delving into her sexual past and matters she is not obligated to testify about due to her marriage with the accused actor.


U.S. Magistrate Judge David Hennessy rejected that request but admonished lawyers for both sides to be better behaved when they meet at a Boston hotel, where Camille Cosby, 72, will face five hours and 45 minutes of questioning.

"I'm really just asking both of you use your common sense, use your experience," Hennessy said at a hearing last week. " ... Let's go in and get the deposition done."


He noted that marital privilege allows Camille Cosby to decline to answer questions about matters discussed privately with her husband.

More than 50 women have accused Cosby, 78, of sexual assault, often after plying them with drugs and alcohol. The allegations, many dating back decades, have toppled the actor best known for his role as the father in the 1980s television hit "The Cosby Show" from his position as one of the United States' best-loved entertainers.

Most of the alleged crimes are too old to be criminally prosecuted. But authorities in Pennsylvania charged Cosby with sexually assaulting a woman in 2005.

Cosby, who is out on bail, has repeatedly denied wrongdoing.

Depositions typically take place behind closed doors, and Camille Cosby is not expected to speak publicly on Tuesday.

Tamara Green filed the Massachusetts lawsuit in December 2014. She was later joined by six other women who say Cosby sexually assaulted them and defamed them by calling them liars.

Cosby has counter sued, accusing the women of defaming him.
