My friend went to downtown and decided to park on the street. He purchased the parking ticket and placed it on the dashboard. When he got back, he received a $450 parking ticket saying that he parked at the disable space without showing a permit. He spent 5 minutes looking around and finally discovered a tiny disable sign on the pole that was turned to the other way. He does not want to pay the $450 at all because he actually did not see the sign. At the same time, he doesn't want to go to court either. Is there any other way to let the court drop the case without going to the court?
