Free Traffic Legal Advice

Last year we received a PCN for allegedly failing to make payment for parking. Our representations were rejected and we took matter to the Traffic Penalty Tribunal, argued our case and won. I have seen several other cases in the news and forums and the general wisdom seems to be that in cases like ours the council have you bang to rights. Even the adjudicator opened our hearing by saying "If I had a penny for every time I see one of these ...." - however after hearing our argument she adjourned the tribunal to deliberate the matter, asked us for further evidence (which we provided) and eventually decided in our favour (hurrah!).

Is there any chance at all that the council can now take further legal action, or is the matter definitely settled?

Thanks!
