Three women who claim Bill Cosby molested them in the 1970s are now suing the comedian for defamation in Massachusetts and issued a subpoena, which his lawyers moved to block Tuesday. Tamara Green, Therese Serignese, and Linda Traitz believe documents from a Temple University-related case will help get Cosby into court, the AP reports.

In the 2006 case, Andrea Constand, a former employee of Cosby’s alma mater Temple, sued Cosby for drugging and sexually assaulting her in his suburban home. Lawyers for the three women issued a subpoena for the papers, as the settlement is protected by a confidentiality agreement. Cosby’s lawyers’ attempt to block the subpoena was founded on the basis that the confidentiality agreement “should not be set aside lightly.”

The papers were filed in Philadelphia, where defense lawyer George M. Gowen asked the Pennsylvania court to wait until a judge rules on Cosby’s bid before dismissing the Massachusetts case.  

Green, Serignese, and Traitz believe they were defamed when Cosby’s agents denied their claims that the actor molested them, and they land among more than two dozen women who have accused Cosby of sexual misconduct. Still, the comedian has denied all claims and is yet to be charged with a crime.

Cosby’s lawyers did not immediately respond to EW‘s request for comment.
