Tamara Green launched legal action against the former THE COSBY SHOW star at the U.S. District Court in Springfield, Massachusetts at the end of 2014, and she was joined in the suit by Therese Serignese and Linda Traitz in January (15). The three women claimed the comic and his legal team had defamed them by calling them liars when they accused the funnyman of drugging and sexually assaulting them in the 1970s.

Cosby's attorney lodged papers to have the case thrown out of court in February (15), but the plaintiffs are now fighting back, insisting the motion to dismiss is "a grasp at straws". They go on to accuse the veteran actor of shying away from facing the allegations by hiding behind his lawyers.

The latest documents, filed on Friday (20Mar15), read: "Cosby claims a privilege to defame where none exists; tries to shield himself from liability, by hiding behind the actions of his spokespersons...

"It is an effort to avoid taking responsibility, and being held accountable, for publishing in national news media false statements that have badly damaged the reputation of each plaintiff."

Green, Serignese and Traitz are seeking unspecified monetary damages.

Cosby's attorneys have denied the allegations. The actor has never been charged with any crime in relation to the accusations.

He is also fighting similar claims of sexual assault and inappropriate behaviour from over 20 other women.
