The former THE COSBY SHOW star is fighting accusations of sexual abuse and inappropriate behaviour from over 20 women, while three of his reported victims recently filed suit, claiming the funnyman and his legal team defamed them by calling them liars when they originally went public with their allegations in the 1970s.

Now Tamara Green, who is pursuing her case at the U.S. District Court in Springfield, Massachusetts, has lodged new papers asking for access to Cosby's confidential testimony in a 2005 suit brought against the veteran by Andrea Constand, a former employee at the actor's alma mater, Temple University.

Constand, who claimed the star drugged and sexually assaulted her in 2004, included testimony from 13 so-called Jane Does who also claimed to have endured similar experiences with Cosby in her civil suit.

She later settled out of court, but Green is convinced Cosby's deposition could prove useful for her own legal action and she wants to have the private documents made public, reports TMZ.com.

Cosby's lawyers have denied all allegations of improper behaviour. The actor has never been charged with any crime in relation to the accusations.
