Who Issues Warrants in Onalaska
In Wisconsin an arrest warrant is signed by a judge. For Onalaska that means the La Crosse County Circuit Court, which hears every civil, criminal, family, probate and juvenile case. A city with a municipal court of its own issues warrants on the tickets and ordinance cases it tries.
A bench warrant follows a missed court date in any of those courts. Whichever kind it is, the warrant is part of the file of the case it was issued in, and the Clerk of Circuit Court keeps that file.
