I am just writing this on behalf of my very busy sister who is not a member and doesn't know how to appeal and challenge these things.
She got a PCN in the London Borough of Richmond Box for straying into a box junction grid on the Upper Richmond Road West on the way to a patient. This was back on the 14th August but the date of issue was the 28th. Is this too long?
Seems to be a TFL administered PCN. I recall some ten years ago, the wording on the TFL ticket wasn't legally compliant which was the basis of a successful appeal at the time. I presume that has long since been corrected?
