Thanks all for your input - really appreciated. I lodged an appeal with Smart Parking and it turns out that the alleged offence is for overstaying my time rather than an invalid reg as I had at first thought. This is the appeal I posted.......
Smart Parking Ltd evidence shows the vehicle entering at 14:06:38 and leaving at 16:18:09 - a total time of 2hrs 11 minutes and 31 seconds.
Please confirm the time allowed on the ticket purchased as I no longer have the ticket. Please also confirm the amount of money entered into the parking machine to obtain this ticket.
Reasons for Appeal
1. There is no (or very poorly visible) signage at the entry point to the site. In this case, I could not know that the "Duration of stay is calculated by the ANPR cameras from the point of entry to the point of exit".
2. There is no time display at the entry point. I could not therefore have known the entry time of my vehicle, upon which you have apparently calculated the "duration" of my stay.
3. At no time during the time that my vehicle was on the premises was I advised of its entry time according to the ANPR cameras, either at the point of entry or at the point of buying a ticket.
4. Some of the signs that I remember seeing do not even mention ANPR entry and exit times.
5. I eventually found a space close to the bowling alley, shortening the distance I would have to carry my autistic son. Logically, I went to the closest ticket machine directly outside the bowling alley. THIS MACHINE WAS OUT OF ORDER - which no doubt your records will verify !!
6. I had to use another machine at a considerable distance, which further delayed the time between entry and obtaining a ticket. At this point I also was not informed of my time of entry.
7. There was a considerable time between leaving the parking space and leaving the site, but I cannot say how much because I was not informed on leaving, of the time of my leaving.
In summary, I was not reasonably informed of your draconian practices at the point of entering the site. Nor was I informed of the ANPR recorded times. Accordingly, I did the only reasonable thing - made sure that my vehicle was in the parking space no longer than the time allowed according to my ticket. I could not say what time I either entered or left the site.
