Yes, IMO don't give the authority any opportunity to dodge the facts.
The authority will see the CEO's photos of the sign prescribed for a parking place with two wheels on the footway* but should compare this/these with my photos taken on ****, the day of the contravention, and ****. Not only do these show that the mandatory Permit Parking Area gateway signs were not present on the day, they're not there now either. And for good measure, GSV shows that they weren't present in Sept. 2024. The ONLY legal basis for enforcing a PPA is tnat prescribed signs are used i.e. advising motorists that any unmarked length of highway is a parking place reserved to the holders of permit(s) specified on the PPA sign.
Absent these signs, the council has no case and the PCN must be cancelled. If it is not, then I should make similar formal representations and if necessary appeal to the adjudicator at which hearing I should apply for costs. I should also complain to the council about its flagrant disregard for its legal duties.
Probably a bit OTT, but I get incensed when councils act in this way i.e. knowingly(it's part of a CEO's duties to report defective signage) fail in their duties.
