Hello,
A friend got 2 x PCN for the same contravention. No idea what they were thinking, given how clear the signage is
PCNs and website payment demand below
PCN 1
PCN 2 
Appeal for PCN 1 (very weak)PCN Validity – Collateral challenge
The demands on the PCN website made are deemed excessive on screen website (see above)...
I do note that a few by Hippocrates has been won upon NoR and then at tribunal showing excessive
Appeal for PCN 2
That the penalty charge exceeded the amount applicable in the circumstances of the case.
Continuing Contravention
The above PCN were sent sequentially, however I was not aware of the initial PCN XXXXXX. Thus it would be deemed disproportionate to punish multiple times, as the driver was not aware.
I would like to draw your attention to the following case:
2160273606
The appellant does not deny the contravention but states that he was travelling to Highgate hospital and was a stranger to the area and made the same mistake twice in one day as a consequence of which he received two PCN's
I am satisfied form the evidence that the contravention did occur. However I also find that as the there is a time lag in issuing a PCN by post, a motorist can unwittingly continue to make the same mistake until they receive notification of the PCN and in these circumstances I find the second PCN issued to be a continuing contravention and allow the appeal in relation to the second PCN under case number 2160273606 but refuse the first PCN issued under case number 2160273661In light of the aforementioned, I was not aware of any subsequent PCN thus ask for this PCN to cancelled.
