Who Issues Warrants in Harrisonville
In Missouri an arrest warrant is signed by a judge. For Harrisonville that means the Cass County Circuit Court, which hears every civil, criminal, family, probate and juvenile case, with associate circuit judges taking misdemeanors, traffic and small claims. A city with a municipal divisions 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 Circuit Clerk.
