How a case moves here
Washington County follows Oregon law on arrests, release, and courts. These rules are the same in every county in the state; the full set covers prosecutors, defense, and jails too.
- Who decides release first
Before arraignment, the jail releases people under a standing order written by the presiding judge of each judicial district, or a release assistance officer appointed by that judge decides. At arraignment, a judge makes the release decision. The standing order sets recognizance and conditional release, not dollar amounts.
ORS 135.233, 135.235, 135.240, 135.245Oregon Chief Justice Order 24-014, Release Guidelines (May 22, 2024)- Time to see a judge
A person held in custody must be arraigned within the first 36 hours of custody, not counting weekends and holidays, unless there is good cause or the defendant asks for more time.
ORS 135.010- Money bail
Senate Bill 48, in effect since July 1, 2022, ended security (money bail) schedules that applied right after arrest. A judge may still require security at arraignment after finding that release on recognizance or conditions is unwarranted.
Oregon Chief Justice Order 24-014, Release Guidelines (May 22, 2024)ORS 135.233- Courts
Circuit courts are Oregon's state trial courts and try all felonies and most misdemeanors. Some counties also have justice courts, and some cities have municipal courts; both may hear misdemeanors committed in their area but not felonies.
ORS 51.050ORS 221.339- Judges and magistrates
Voters elect circuit judges on a nonpartisan ballot to six-year terms, and judges must be members of the Oregon State Bar. Justices of the peace are elected to six-year terms. A justice of the peace must be a bar member or complete a judicial course, except in justice courts of record, where bar membership is required.
