I used to work for Islington Brough Council's Estate Parking Section, if you were making a parking appeal against a fine then you would have to provide full contact details, this was for two reasons. A simple check to see that you were who you say you were, and so that we could issue a refund if our investigation showed the fine/clamping/towing to be unfair or contrary to the operating regulations, a refund can only be issused with a full name an address.
