A judge delayed a ruling Monday on an attempt by comedian Bill Cosby to dismiss a case filed against him by model Janice Dickinson, who is suing Cosby for defamation. Dickinson alleges that Cosby drugged and raped her back in 1982.

“Dickinson sued Cosby in May over his denial of her claims,” the AP reports. “She says his former attorney wrote letters to news outlets denying her allegations and implying the organizations could be sued if they used the claims in stories.”

Dickinson has also said her publisher refused to let her include an account of her allegations in her 2002 memoir.

“On Monday, Los Angeles County Superior Court Judge Debre Katz Weintraub delayed a ruling until March 29 and ordered attorneys to file new briefs on whether the denial by Cosby’s former lawyer constituted a legal communication about possible litigation,” the AP reports.
