@Hippocrates - many thanks for your timely response.
Just checking on my intended course of action. I intend to the challenge the PCN via the Penalty charge notice challenge portal on Harrow's GOV.UK website
I will make the following representation:
"Dear Harrow Council,
I make these formal representations against PCN - HR7580598A.
1. I was not familiar with the location in question as evidenced by the address to which the PCN was sent to.
2. I did not see any signage as it was inclement weather. This is in part evidenced by the fact that my headlights are on 0829 in the morning, and also that there is clear evidence of large amount of surface water on the road in the CCTV footage provided.
3. The video and photos provided do not show any upright sign allegedly passed.
In light of the above, I would be grateful if you could please cancel the PCN."
Is it worth me citing this judgement too -
decision - or should the text in speech marks be sufficient.
Presumably if they come back and contest I should come back here with their response, or at the very least let you know the outcome?
Thank you for your assistance.
