How a case moves here
Mariemont follows Ohio law on arrests, release, and courts; 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.
Ohio Rev. Code 2937.011(J)Ohio Crim. R. 4(E)(2)- 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.

Read from the statutes and court rules cited, 2026-09-30. Crim.R. 46 was repealed July 1, 2023; bail rules now sit in R.C. 2937.011.

Per 100k: offenses per 100,000 people the department polices, 2022 to 2023 added together, full years only, beside Ohio's rate over the same years. – means too few for a rate: the count is under 20.
* 2024 to 2025: reported for part of the year only, so the count is short and the year is left out of the rate.
