The form of criminal trespass to which you are referring is trespass at a location where it has been communicated to you that you are not welcome. IF you have been charged with this/these offenses, consult with legal counsel without delay. If you are not the defendant then your interest in the answer here is unknown.
This is a defiant trespass charge. Under this particular subsection, the defendant was specifically told not to be in the area, either by personal communication or via posted sign. Time to speak to an attorney.
