I did this which is better. They'll probably reject at this stage though.

I am challenging the PCN as the contravention did not occur. No part of my vehicle was adjacent to a part of the footway lowered for the purposes set out in the legislation.
As you can see from your CEO’s pictures, only a trivial portion of my car extends beyond the sloping kerb to the fully lowered part, and I enclose my own picture showing that this sloping kerb is adjacent to a pedestrian gate and is at the opposite end of the lowered portion of the footway.
At the other end is a vehicle access gate but my car was not in any way adjacent to this. It is clear that the lowered area extends beyond where it should be.
I only parked there briefly while I collected an iPad from a friend and I was careful to ensure I was well away from the vehicle gate.
I trust that given no contravention occurred you will cancel the PCN and look forward to your early confirmation.
