Jersey City, NJ parking ticket error?

I'm not sure about New Jersey but in my state I issued a speeding citation to someone and accidentally checked the radar box instead of "pace". On the citation, the officer must indicate how you measured the person's speed, by use of radar or pacing them with your patrol unit. While we were both standing in front of the judge, I explained that I had mistakenly checked the radar box but had actually paced the driver. The judge immediately threw the case out. I think that it may be worth a shot to try to contest the ticket. If an officer cites you for the wrong violation it can be dismissed. Good luck!
