Well, she didn't succeed in getting the AVO against Peter. There's
little that can be done to stop people from seeking AVOs in the short
term. If she persists in making meritless applications, then the court
may ultimate declare her a vexatious litigant, meaning that she'd need
the permission of the court before even making an application, but
courts are very reluctant to take such a step.
As for the actions of AVN against the parents of the child who died of
whooping cough, it arguably amounted to stalking, which is an offence in
NSW. Proof beyond reasonable doubt against a particual person could be
difficult, though an AVO might have been obtained. An application would
have to be made.
All in all, the AVN seems a thoroughly vile organisation.
Sylvia.
