In the US, a plaintiff can go to a judge and make allegations against another person and persuade the judge to grant a temporary order of protection without the other person being present. Let's say both parties live in the same building, the judge can order the defendant not even to say Hi or even look at Plaintiff --and if he does, off to jail. The case can drag on for years and then later on the case can be dismissed, plea-bargained, or tried.
