normally, a non molestation order would be put in place to stop one person from carrying on a course of action against another.
Acts such as Acts or threats of violence, Use of abusive language, Stalking, Abusive messaging e.g. text messaging or Facebook messages can all be considered as molestation.
A one of incident would be unusual.
The person seeking the order would have to provide the evidence to back up their allegations to the court when applying for the order.
When you say police attended and stated you had committed no crime, that would be in relation to a criminal matter for which you could have been arrested. Not all molestation matters would warrant an arrest by police, but could be sufficient to seek an order on.
If the party seeking the order lies to the court or deliberately gives false information, then yes that would be perjury and they could face contempt of court and face prison.
bear in mind errors do also occur on dates, so do not put to much weight on the that that they have changed dates. However, certainly raise this matter at the hearing, as it would cast doubts on what they say.
