Ohio Rev. Code Ann. § 2701.07

When, in the opinion of the court, the business thereof so requires, each court of common pleas, court of appeals, and, in counties having at the last or any future federal census more than seventy thousand inhabitants, the probate court, may appoint one or more constables to preserve order, attend the assignment of cases in counties where more than two judges of the court of common pleas regularly hold court at the same time, and discharge such other duties as the court requires. When so directed by the court, each constable has the same powers as sheriffs to call and impanel jurors, except in capital cases.
