I stopped my car in front of school on the yellow zig zag line to allow two members of public to cross the road. In the mean time, a car coming from behind tried to overtake from my right hand side (possibly not knowing why my car was stopped). It was my natural response to look over my right shoulder before I could move away safely. But in these split seconds (and while looking right) my wife who had dropped my child to school had opened the passenger door on the left and was boarding the vehicle. I allowed her in and moved away safely. However, the overall stay still did not exceed 5 to 7 seconds in which all the above occurred. Please note I never stop even to pick up my wife from the front of the school and she knows it. But on that day, she thought I had stopped to pick her up without realising I had stopped to allow members of public to cross the road. When I got the ticket I was not sure why I received the ticket because in last 4 years of dropping my kids to school I never parked in front of school on yellow lines. The still picture only showed my wife opening the car door? I wanted to see the video evidence and emailed council. Instead I received surcharge notice which required me to pay £165 instead of original £55. I wrote to them again and requested for the video evidence. They then revised the amount to £55 but still did not send the evidence. I called back for the evidence and now finally I have received the video evidence which confirms all of the above. But it confirms one more thing. The video shows I went pass my wife by few yards and stopped only when members of public were crossing the road. It then further shows my wife rushing towards the car from behind on the left hand side (while I was looking right) in an attempt to open the door while I was about to leave. If my intention was to allow her to board I would stop exactly where she was in front of the school door. But this was not the case. Do I stand a chance in the appeal? What shall be the grounds? Is this a long stay? Is there a provision for stopping to allow passenger to board, although this was not my intention?
