How a case moves here
Arlington follows Washington law on arrests, release, and courts; 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.
