yep chesterfield is right you cant be charged for same offence twice, just be careful though that its not a scam, there are some going around where your money is not ac tually going to the councel but to some dodgy B@stard trying to get more money out of innocent people.
So far Ive had a total of 16 parking tickets, I the crappy penalty notices at home as trophies, as Ive been let off every one so far. If anyone gets a parking ticket and needs to know how to get let off and get a letter of apology from the councel pm me. I help my friends out all the time to. I found out how to do it from a dare I say it a fit traffic warden who was issuing me a ticket told me the loop hole out of it.
