For a contravention application to succeed, you need to prove that Mum has, without reasonable excuse, intentionally failed, or made no reasonable attempt to comply with, the orders.
First, how can you prove the children were unsupervised for 2.5 hours? Nine-year-olds don’t make for reliable witnesses in a Court of law, and unless there was an observer who is also willing to provide an affidavit and face cross-examination in Court, any evidence you have from other observers is hear-say, which is not admissible in Court. On top of that, what is considered ‘supervised’? Presence of another person? Presence of a sibling? Presence of an adult? Presence of an adult known to the children? Presence of an adult known to the children and agreed by the parents?
Second, even if you do prove it, what outcome are you expecting? It would be considered a minor contravention, so at best, the Court will order Mum enter into a bond; at worst, the Court will remove the order all together. Since the Court is not in the business of micro-managing parents and must try and make orders that minimise conflict, I would say it’s more likely the Court will remove the order, or at least amend it to clarify what’s considered supervised or unsupervised.
The Criminal Code in Queensland does limit children being left unsupervised for an unreasonable amount of time, but the police obviously don’t have any interest in prosecuting because they, too, will have a lot of trouble proving beyond reasonable doubt that the children were left unsupervised for an unreasonable amount of time when the only evidence available is your word.
Parenting orders remain in force until a child turns 18. May I ask, what happens when the child turns 15 or 16 or 17? Will she not be allowed to see a movie with her friends unless escorted by one of her parents? Will she not be able to attend a concert without invoking her father’s wrath against her mother and risk having him call police/DOCS/Family Court? Have you considered what impact that might have on her friendships? Her personal development toward independence? Her self-esteem? Her identity?
Have you considered what impact your actions will have on your daughter’s relationship with you?
