And how is that different than a restraining order? Different label, same basic concept.
Different in almost every conceivable aspect.
A "restraining order", AVO, ASBO, etc applies to a person and generally restricts who they can contact and how close they can be to another person.
A PSPO applies to everyone and forbids them from otherwise perfectly legal activities in a specific defined geography.
Specific defined geography? I don't understand what that means nor what it has to do with her right to pray in her head being taken away.
