yeah mate I'm a troll. That is why I've spent the best part of an hour punching the keyboard to help you. I'm trying to help you...
You had an interim avo made. It stands until a magistrate tells you differently, not someone over the phone. This isn't play school this is the law. You get a piece of paper at the end of it to tell you the rules. If your defence is "but someone on the phone said" you're stuffed. Do you have a customer reference number? Did you get their name?
So my experience with child support among other govt agencies is there is always a record kept. So if you call the register and ask if they can check the records for the conversation on the date you claim to have been told the AVO is cancelled, you might get some joy. Yup - I'm a troll. Giving you advice on how you might be able to get out of this. So call the registry on Monday and ask if there is any record of anyone telling you the thing was dropt. I'm thinking you'll find you mis-understood.
So you have an email that proves you were not served the final avo? means nothing. WHY? because you have nothing to prove that the interim avo was dismissed (other than you saying 'someone' told you so - which isn't a defence).
So what now? Well where are you up to? You have been charged with breach avo? What I'm getting at here is you really have nothing to go on as far as undue process. ANd something you wrote above worries me. "I only provided mc on the day so the applicant would not have had forewarning. " To what benefit? For what purpose? to make them take a day off work to attend court? To screw them around? Hmm. Seriously, if it isn't any of those options, please tell us so we can try and help you, not troll you... I'm guessing MAYBE you could argue that the breach of the avo was a result of not being sereved the final. But 'your honour, i threw the beer bottle because I didn't have the final avo to tell that I wasn't allowed' isn't gonna be all that good. You're gonna need to establish you didn't throw it, you were not there, you didn't even speak to the neighbour.
So your original question was 'do you have any rights' YEP. A defence? YEP.
You have the right to plead innocent and if you didn't do it, then there is your defence. But IF you did anything that breached the avo then your stuffed (UNLESS - as mentioned above you can get some documentation from the registry to say they informed you that the thing was dismissed).
