Section 89?

Well you have the common ault thing, which is nothing much really, and then you have the section 89 which I would imagine is a section 89 (1) police act which is aulting a police officer (could be 89(2) which is obstructing a police officer) - may be both. The more serious of the two is the ault Police. If the CPS wish to run this, then you'll get your day in court. If you plead guilty, I'd imagine you'll only get a fine of around �200 if all you have is a previous caution. You'll be very unlikely to get a custodial. Don't get mad at the Police. Domestic incidents are on the Police hotlist, and will end up with an arrest if there is an offence, no matter how small it is. If your ex made the allegation, they have to act on it.
