Draft reps:
Dear London Borough of Barking & Dagenham,
I challenge the alleged contravention because the footage does not show my vehicle failing to comply with signage prohibiting entry or waiting to the pedestrian zone, as my vehicle was stationary outside of the zone.
I would suggest that if there was any intrusion, it was truly de-minimis.
It follows that in the circumstances of the case, the PCN should be cancelled.
Yours faithfully
I'll be surprised if the council give in that easily, but post up the rejection when you get it.
