If you are looking to appeal a parking ticket, you must do so through your local parking violations bureau. To appeal a parking ticket, you must start the process the moment the ticket is issued. If the meter was faulty or blocked in any way (by gum, a sticker, snow, etc.), document it. If there was improper signage, blocked signage or no signage at all, documents it. In addition, if there was faded or chipped paint that was not readable or confusing, document it. The best way to document it is to take pictures. Additionally, inspect your ticket to insure all details are correct. If there are faulty details on the ticket, you may be able to win your appeal based off that. Moreover, you may want to request paperwork that shows the last time the meter was serviced or calibrated, to ensure it was accurate when you got the ticket.
