The crux of the matter here, as Soil has pointed out many times in the thread is that the lady clearly ignored a Magistrates' Court Summons. A summons is not a party invitation - it's a summons. Fail to attend and you'll be hit with a standard penalty and no discounts based on the evidence presented. If it's a more serious matter you'll find that a warrant is issued and the police come along to bring you to court, most likely after a night in the cells.
Bother to show up and you'll be fined based on your income, given a discount if you plead guilty at the first appearance and be allowed to give your mitigation. You may even want to challenge the charges and go to a trial. All of that is possible if you show up.
Agreed.
All of this is explained in plain English (and Welsh in this case) in all the documents that the lady would have received with the Summons. She has quite obviously ignored this as she did not appear and also obviously did not complete her earnings details.
