I'm a little confused. I parked overnight near campus and forgot to pay the next morning. Naturally, I figured I would get a violation and I did, at 12:00PM. I just received a letter in the mail 2 weeks later notifying me of the same citation, but at another time, 9:30AM. Two separate tickets for the same violation? I also did not even get a ticket stub for the first one. Is there any way this is contestable?
