Blurred PCN

Hi guys
I wonder if you could help
In Feb I received a PCN in a residents bay (It was outside our house) for not displaying any tickets
However a Visitor Permit was displayed from 9-10am and 10-11am

The parking attendant failed to see this in the car (it was displayed in the corner, it's a mini so has a black part at the bottom of the windscreen but the ticket could be seen.

Anyway, I know in our area these parking attendants wait in parked cars for people to catch them out.

The photos supplied were not clear enough, and so when I appealed my case providing my visitors permit with the date/times written on, the borough rejected it. I then appealed again which was a Representation, the decision was again taken by the Borough and they rejected the claim again.

It says they don't really consider photos evidence, so what if the Parking Attendant is just trying to find cars to put tickets on that are legally parked, but ignoring tickets displayed in the corners of windscreens

I am again going to appeal to London Tribunal, but is there anything about Blurred Images and PCN's, this is really unfair as I am a resident and I would never park illegally knowing that they wait in parked cars on our street to put tickets on cars

Please someone advise?

The Mini has a black almost see through line at the bottom of windscreen so you need to look over it. I wonder what I could do in this case, or write in my appeal to London Tribunal except that the contravention did not occur. Is there any way I could attach images here, it's not allowing me to add the image links.
