Thank you.
I think it's fair to say that the driver was not spending 2 hours just perusing the middle aisle in Lidl... That's not to say they didn't shop in there, but I think it would be a tough one to suggest they were in there for 2 hours. That being said, I am only speaking with the keeper, not the driver. It is equally possible that the car exited and re-entered, Neither I not the keeper could answer that.
It might be interesting to test the validity of the "invitation to pay" in court. The general consensus seems to be that any error will render the PCN unenforceable, but without case law, it's not perhaps possible to say.
There is only 1 Lidl, but with a large ASDA next door, the car parks tend to be used interchangeably, and have walkways between them. Again, if the address is in any way unclear, could it be a breach of PoFA and lead to the case being thrown out?
Regarding the photo evidence, all Parking Eye have produced is a photo of a VRN and some lights. There's no indication as to where the photo was taken, what the vehicle is or any signage that would have been in view, particularly at night.
Looking at the streetmap photos from 2023, one entrance has good, visible signage, but the other does not, as it is set away from the entrance, unlit and not visible until the car has turned well into the car park itself. I will have a mooch around the car park when I am next in town and take a look at the rest of the signage.
