Who Issues Warrants in Lewis and Clark County
In Montana an arrest warrant is signed by a judge. For Lewis and Clark County that means the Lewis and Clark County District Court, which hear felonies, civil cases, divorces, probate and juvenile matters; the Justice Court, which takes misdemeanors, traffic cases and small claims, issues its own warrants on the cases before it. A city with a city and 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 District Court keeps that file.
