f16 - the 'leaving site' lark only applies to the driver as they are the one supposedly making the contract. The passengers can do what they like. There was a case a few weeks back where the driver left left site, but his wife stayed on site - he got a ticket.
I wish the original poster all the best. Use the correct terms in your appeal and you will win at POPLA.
Not everyone knows where MSE is so you are wrong on that - if they did, then more than 1% of the issued tickets would be appealed. I only came over as I'd picked up a link saying that the wrong advice was being given to people.
I thought the whole point of these forums is to HELP people. I didn't realise there is so much ill-will to others from the CAG team. I occassionally go to the car parks and give leaflets to ticketed drivers telling them how to fight their tickets - so I'm no newbie (only to this forum).
Finally, It's toys out the pram time - I'll not go where I'm not welcome - I'll deregister.
