"The suit and the allegations it contains aren't worth dignifying with a response," Emmis Radio President Rick Cummings said in a written statement. "Emmis doesn't have the ability to keep a good show off the air."
Muller filed the civil suit in Cook County Circuit Court in Chicago, according to trade publication Radio Ink.
Muller's "Mancow's Morning Madness" program was based at Emmis' WKQX Chicago until June 2006, when the host's contract was not renewed.
Muller's suit alleges WKQX personalities disparaged Muller on the air after his contract expired and aired a bit in which a caller purporting to be Muller made obscene comments. According to the suit, the station also sent packages of rotting meat to advertisers to symbolize a "dead cow."
The suit also alleges that Crawford Broadcasting's WPWX Chicago decided not to pick up Muller's syndicated program because Emmis provided it misleading financial information.
