Back in June I received a PCN for parking outside my residence on a private road on faded DYLs. This is my preferred parking space and I have been parking there for 9 years now, on a daily basis, and have never received a PCN for doing so.
I initially didn't consult these forums as I wrongly assumed it would be an easy appeal given the PCN was issued on a private road, however, Barnet have now rejected both the informal and formal representations. Attached below is the NoR. I no longer have the initial appeal text (or its rejection) or formal reps, as I've recently moved address and misplaced these (Yes, I've already updated V5C).
I intend to appeal at tribunal based on the fact that parking enforcement is not under Barnet's jurisdiction at this location and that no valid TRO exists at this location. I have done some homework and have attached my findings below. I would be grateful for some expert advice on here on whether these are strong enough grounds for appeal, and if not, what alternative argument I should be making?
