I got a PCN today and wondered if anyone could advise on my appeal chances. I paid for the ticket and put it on my passenger seat as the sticky surface leaves residue on the windscreen and only the day before I had a parking ticket slide down my dashboard and get trapped (its still there). I returned within the time to find a PCN on my windscreen and didn't understand. I phoned my dad who said it was most likely because the council seems to think on the passenger seat is not 'clearly displayed'. This being the case, if legally i am at fault for not displaying, I will pay the fine before it doubles. Even though its horrendously unfair when I bought a ticket and displayed it face up. However I am wondering about the contravention code I was issued - number 11P. Looking this up it appears to be "Parked without payment of the parking charge". This contravention didn't occur as I can prove with my ticket. If I committed a contravention it would seem to be code 6 "Parked without clearly displaying a valid pay and display ticket or voucher". This would mean the code listed on the PCN is wrong and therefore the PCN is invalid. Edinburgh council doesn't list code 6 on their site however so are they lumping them together into code 11 and did I contravene code 11 by incorrectly displaying? P.S. the envelope my PCN was in has a sticky strip along the top (and the bottom I tore off) that says 'the cover strip is removed by the officer' but this hasn't been removed - does this by chance invalidate the ticket? (long shot I know)
