California Code section 527.6 (B)(3) is an harassment charge, whereby unlawful violence, a credible threat of violence, and a knowing and willful course of conduct that alarms, annoys, or harasses a person and that serves no legitimate purpose is alleged.
The course of conduct must be such as would cause a reasonable person to suffer substantial emotional distress and must actually cause substantial emotional distress.
Upon the filing of a petition under this section, the person filing may obtain a temporary restraining order (with or without notice to the person who is allegedly harassing, if great or irreparable harm may result otherwise). Within 15 days, or 22 days if a TRO has been issued, a hearing on the injunction will be held. The person accused of harassment may file a response that explains, excuses, justifies or denies the alleged harassment or the person accused may file a cross-complaint.
As to California Civil Code 46(3), the section on slander, this is charged when a person has been directly injured with respect to his office, profession, trade or business by an imputation of general disqualification in those respects of which the office or other occupation peculiarly requires, or by an imputation of something with reference to this office, profession, trade or business that has a natural tendencey to lessen its profits.
So, basically, you are charged with harassment and the slandering of some sort of business whereby the person harassed and slandered has felt threatened in some way by your actions and his business reputation has suffered as a result.
