Who Issues Warrants in Casper
In Wyoming an arrest warrant is signed by a judge. For Casper that means the District Court for Natrona County, which hears felonies, civil cases over $50,000, divorces, probate and juvenile matters; the Circuit Court, which takes misdemeanors, traffic cases, small claims and civil cases up to $50,000, issues its own warrants on the cases before it. A city with a municipal court of its own issues warrants on the tickets and ordinance cases it tries.
When a defendant misses a court date the judge issues a bench warrant, and either kind of warrant lives in the court file of the case, kept by the Clerk of District Court.
