Fraudulent Checks Jurisdiction

My question involves criminal law for the state of: SC

I could go on and on about the foolishness I have gotten caught up in during my youth but my main concern is a bunch of fraudlent checks for which I was convicted. Now, I accept responsiblity but my bank was also culpable for mis-information they provided me. In any case, I was under the assumption that the warrants were issued in the jurisdicition in which they were written or passed. Looking over the warrants, I notice that they were all written in the city but signed by county magistrates and even listed on the warrants as violations that happened in the county. The checks were passed on to a check recovery agency, whom actually pursued the warrants. Their agency is located in the County, but I would still assume the jurisdication falls in the location of the actual merchant that received the check. Any insight would be appreciated.

You mean, years and years ago you were convicted of passing fraudulent checks? And now you want to try ot attack your convictions... for jurisdictional reasons not obvious from your post? You probably waived any objection to jurisdiction "way back when". Beyond that, either explain better what you're trying to get at, or consult a criminal defense lawyer.
