I think you and I have a very different understanding of how the Juvenile court system functions. Protection for Juveniles is always foremost in these sorts of cases, and no order needs to be issued because all players know the rules.
You are arguing a pathetic technicality that would not last an instant in front of a judge. The judge would simply look at the violator and say "You know better."
The judge granted a motion for expungement filed by one of the Duggar sisters. That's how the judge had jurisdiction over the matter.
You are simply incorrect if you think a judge can otherwise (i.e. without the expungement motion/order) wave his hands & order something for a situation that was never before him in court.
Protection for Juveniles is always foremost in these sorts of cases, and no order needs to be issued because all players know the rules.
Once again, you're talking about court cases, not police records. Without the expungement motion & order, a court has zero jurisdiction over a matter never before the court. This is Government 101 stuff.
