Too much of this goes on in some strata schemes. No one should live in fear and this type of intimidation is not to be tolerated.
How about this action plan:
1) seek support of your fellow EC members (if they are hesitant tell them they may well be next in line) to get advice from a Strata Lawyer and make the applications open to you at the CTTT, which I see have been touched on in other posts.
2) walk in to your nearest Police station and seek an AVO, most times the Police will issue a provisional AVO or other type of order. It will be helpful if the OC provides a letter confirming the issues/threats you are facing from one or more of the occupants.
Of course this won’t endear you to the person/s you have the order served on but, hey, they don’t like you already. No seriously, use the tools you have at your disposal and the AVO is a good one, it normally shuts them up and gets them back in the box.
If you go down this line and they break the order don’t hesitate to get them locked up, it will only happen once unless that are totally brain dead..
Best of luck.
