Pima County Vacated My Bench Trial, Then Issued A Warrant For Failure To Appear. Can They Do This?

[NWC1827]

I received a camera traffic ticket in Arizona. I gave proof that is was not me to prosecutor. Her assistant failed to file paperwork correctly. A While later I get arrested for not taking care of this ticket. A Bench Trial is set. The trial is then Vacated with no additional information. I figured they found my previous evidence that i did take care of ticket and dropped charges. a few months later I get arrested for failure to appear at Trial that was vacated. This has happened 3 times. what rights do I have?

This website is based in the UK, so it's extremely unlikely that there's anyone here who's familiar with Arizona state laws.

Unfortunately the US equivalents of this site (such as Answerbag.com and Answers.yahoo.com) seem to be poorly moderated, meaning that they're usually full of trolls and spammers. However you might find someone who knows about Arizona laws on City-Data.com:
