Wow you were spot on, we received the NTK yesterday. What is the appeal letter supposed to say? Thanks for all the help

My wife has received a ticket from Car Parking Partnership while parking at Kings Mill Hospital, Mansfield she has a staff permit paid for by her to park there but there was no parking available that day and she parked in a non marked parking. They gave her a ticket for "Parked as to cause obstruction or inconvenience to others". Unfortunately we have waited a little to long to address this, but hopefully we are still in a window to receive some great advice from you all. If we need to appeal or what ever. The date on the ticket is 06/08/2014. The fine they are wanting is £50 if paid in the first 28 days and 1/2 price for paying in 14 (both have passed now) My wife has photographic evidence of where and how she was parked. What is the best advice to move this forward?

Just a quick note CEL has not gotten a hold of me at all

I was given a parking notice by Civil Enforcement Ltd. The parking lot had one hour limit for parking. I was there for 1 hour an 15 minutes approx. I was doing work for one of the shops, window cleaning and wall cleaning. I informed Civil Enforcement why I was there and they said that it did not matter and would not accept my appeal. I made my appeal to POPLA and the points I used were that if there is a requirement for me to register my vehicle to work from the parking lot, that is a Term and Condition of my staying and since that was not on the sign and not part of the Terms and conditions that I entered on then the parking was not properly signed. I also noted that I moved my van after I finished the windows to another spot in the back because I still had to do the walls inside. Civil enforcement has said in their appeal response that they can not monitor movement inside the parking lot and the sign does not specify that a vehicle must leave the parking lot and reenter to be consider reparking. Civil enforcement made a 15 page response to my appeal of which 11 paragraphs actually pertained to my appeal. They made appeal points that I did not even submit. When POPLA made their opinion, they addressed what Civil Enforcement said my appeal points were and not what I actually submitted. I challenged this and wanted the qualifications of the assessor to make a legal opinion and they refused to supply the information. I said that they should audit this case and again they refused. They said I had no choice at this point but to pay the ticket (that is POPLA saying this). I also made not that all the funding from POPLA comes from these companies that issue the tickets. So that is where I am at. I think I would like to take this to court, Don't know how to get that started, or if there may be some better advice out there.
