How a case moves here

St. Louis County follows Missouri 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

For state charges, a circuit or associate circuit judge usually sets release conditions on the warrant issued after the prosecutor files, then reviews them at the initial appearance. For city ordinance arrests, jails apply municipal bond schedules. Whether jails use money schedules for state charges is not confirmed.

Time to see a judge

A person arrested without a warrant must be released within 24 hours unless charged and held on a warrant. Once held on a felony warrant, the person must see a judge within 48 hours, not counting weekends and holidays. A person still held gets a detention hearing within seven business days.

Money bail

Missouri courts may set money bail. Since 2019 the court rule presumes release on recognizance and tells judges to consider non-money conditions first and set money only if those won't do.

Courts

The circuit court tries felonies and state misdemeanors; associate circuit judges within it often hear misdemeanors and early felony stages. City ordinance violations go to municipal divisions of the circuit court, run by each city.

Judges and magistrates

Circuit judges serve six-year terms and associate circuit judges four-year terms. In most circuits voters elect them in partisan elections. In the City of St. Louis, Jackson County, and circuits whose voters adopted the plan, the governor appoints from three nominees picked by a nonpartisan commission, and judges then face retention votes.

Read from the statutes and court rules cited, 2026-09-30. Some of this is medium confidence and still being checked. Which circuits besides St. Louis City and Jackson County use the nonpartisan plan (St. Louis County, Clay, Platte, Greene are commonly listed) was not confirmed from a primary list. Jail bond schedules for state charges and offense limits on them were not confirmed. That St. Louis County and Jackson County jails are run by county corrections departments rather than the sheriff is from general knowledge. Associate circuit judges' lawyer requirement is set by statute, not read.
