Appreciate your reply and, I too, have been guilty of not displaying/ displaying an out of date badge/ forgetting to put the clock on show on many occasions. This time, however, all was correct. Confidently, I went to appeal and was going to use the photographic eveidence but it was very unclear. The response from the council states that they have checked photos and enclosed them. They didn’t enclose them!!!
I thought you implied you’d seen the photos as you said they weren’t clear. If they aren’t providing you with photos and you are up for the stress of a fight (and the risk of the fine not being discounted for early payment) then I’d appeal.
