How a case moves here
Thurston County follows Washington 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
A judge or court commissioner sets release at the preliminary appearance. Before that, a district or municipal court may adopt its own bail schedule that the jail applies; adopting one is optional and court by court.
CrRLJ 3.2CrR 3.2.1RCW 10.99.045RCW 3.42.010- Time to see a judge
A judge must decide probable cause within 48 hours of an arrest, counting weekends and holidays. The person must then appear before the court by the close of business on the next court day.
CrR 3.2.1(a), (c), (d)- Money bail
Court rules presume release on personal recognizance except in capital cases. A court may require a bond only after finding a likely failure to appear or a danger, must use the least restrictive conditions, and must consider the person's financial resources when setting a bond.
CrR 3.2- Courts
Each county has a superior court, which tries felonies. District courts hear misdemeanors and gross misdemeanors and can hold felony preliminary hearings, and municipal courts hear cases under city ordinances.
RCW 2.08.060RCW 3.66.060RCW 35.20.030- Judges and magistrates
Voters elect superior court judges on a nonpartisan ballot to four-year terms. District judges are also elected for four years and must be lawyers, except in districts under 5,000 people where a lay candidate passed the qualifying exam by 2003. Mayors appoint municipal judges for four-year terms unless the city makes the job elective.
