Union County

Union County follows Ohio 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

Every court must keep a bail schedule for misdemeanors so people can be released before they see a judge. When no judge, magistrate, or clerk is available, the sheriff, police, or jailer may set bail from that schedule. Only a judge or magistrate sets bail on a felony.

Ohio Rev. Code 2937.23Ohio Rev. Code 2937.011(I)

Time to see a judge

A person arrested and still held must see a judicial officer for a bail hearing by the second court day after arrest. After a warrantless arrest, a judge or magistrate must also review probable cause within 48 hours, but that review can happen on paper. If the person had no lawyer at the first hearing and is still held, a second bail hearing with appointed counsel follows two court days later.

Money bail

Ohio courts may set money bail. The constitution tells courts to weigh public safety, the charge, and the person's record when setting the amount. State law requires the least restrictive conditions and any money terms to be the least costly that will bring the person back to court.

Courts

Each county's court of common pleas tries felonies. Municipal and county courts hear misdemeanors and hold first appearances in felony cases. Mayor's courts in some cities and villages without a municipal court hear ordinance and traffic cases.

Judges and magistrates

Voters elect common pleas judges to six-year terms on a ballot that shows no party, and judges must have six years of law practice. Municipal and county court judges are elected the same way and must also be lawyers. A mayor, who need not be a lawyer, hears mayor's court cases or appoints a lawyer as magistrate.

Pretrial practice

Mapping Pretrial Injustice listed its risk tool in 2021 as the Ohio Risk Assessment System Pretrial Assessment Tool (ORAS-PAT).
