PCN Appeal - distance to notice

[ParkyParker]

I parked in the end space of a long line of bays in Highgate today. I was a bit surprised to find the space, and so I looked carefully for any notice that they might be restricted, but found none. There was a lamppost adjacent to the point I'd parked, and as there was no notice there, I assumed that it was in fact okay.

Sure enough when I returned some hours later, I had a PCN (Code 12). I went in search of the notice, which I found fifteen cars along the street, and at a height of about 1m. This seems unreasonable. How far does one have to look for a notice? Is there any restriction on the distance that a notice can be for the governed space? I have photographs and a movie.

 

Thanks for any advice.
