Off the top of my head I don't know of any cases that didn't involve sales of good and services, but clearly the law is available, CBS is selling a service and bad goods, and subject to public policy in a Presidential Election. Certainly they have been unethical immoral, and unscrupulous.
...."For example, California courts have tried to define "unfair" through a process that resembles "rule of reason" analysis - examining reasons, justifications and motives of the alleged wrongdoer and weighing the utility of the defendant's conduct against the gravity of the harm to the alleged victim.
