two things here -
1. Any reps submitted must say why the person parked there, and not in the usual place, (doctor at hospital etc)
2. The PCN is flawed and positively misleading in the penultimate paragraph on the rear of the PCN. They have worded it such that only if further representations are to be sent, they must be submitted against the PCN. This is in direct contradiction to the wording in the regulations. See3 here in chapter 1, Regulation 3(1)(c) :-
https://www.legislation.gov.uk/ukdsi/2022/9780348232752/part/2/chapter/1The point of this clause is to warn a PCN recipient who may also be the owner, that even if informal reps are submitted against the NtO, the reps must be submitted again if a Notice to Owner is received. If no reps are submitted against the NtO because the owner thinks to himself that they have already been submitted, the matter will progress to the Charge Certificate stage, and the matter cannot be reverted because the NtO has been ignored.
