Jared Howe has hinted he's had some success (the words he's used are a bit vague; not sure if he means HIS success or has observed others doing so) with the defense of asking the court to prove the law applies to you as a direct question of jurisdiction. It won't make the warrants go away per se, but use it enough in the same jurisdiction and perhaps the odd judge will stop signing warrants against you with an "ah fuck no, not him, don't want THAT guy in my court again!"
