Who Issues Warrants in Lake Oswego
In Oregon an arrest warrant is signed by a judge. For Lake Oswego that means the Clackamas County Circuit Court, which hears every civil, criminal, family, probate and juvenile case. A city with a municipal and justice 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 trial court administrator keeps that file.
