In determining what a domestic violence order is, you have to understand the different jurisdictions of the Magistrates court, which has a civil jurisdiction and a criminal jurisdiction. A DVA falls within the civil jurisdiction until there is a breach, which then becomes a criminal matter.
This is a very important distinction. In terms of the actual breaches, they can start as a technical breach, such as a text message to the aggrieved breaching a condition on that order or it could be as serious as a physical assault on the aggrieved, which breaches the standard conditions of the order.
In terms of court processes, there are various tools used in court to try and reduce the sentences and penalties. This depends on the seriousness of the breach. The penalties for a breach can range from a mandatory fine to probation to a period of imprisonment.
