Liable, why are you always such a wiseguy? People are asking for advice, not wisecracks.
I would say that this case would depend on how bad the name error is. If your name is Bob Smith and the officer wrote down Bob Smyth then you probably would have no case. However of you're Bob Smith and the name on the ticket said Phil McKrevice then you may have a case. Even if you admit that you were indeed stopped by the officer you would certainly have a good reason to question the officer's state of mind at the time of the incident if he made such a ridiculous error.
