A defamation battle between a woman who accused Bill Cosby of sexual assault and a former prosecutor who declined to charge the embattled entertainer is heating up in discovery, with both sides claiming the other failed to produce requested records in the case.

Plaintiff Andrea Constand and former Montgomery County district attorney Bruce L. Castor Jr. have both filed motions to compel, and Constand’s motion is also seeking sanctions against Castor. Constand sued Castor in October 2015, alleging that he defamed her in his statements about the Cosby case.
