Ohio Revised Code General Provisions § 1.52

(A) If statutes enacted at the same or different sessions of the legislature are irreconcilable, the statute latest in date of enactment prevails.

(B) If amendments to the same statute are enacted at the same or different sessions of the legislature, one amendment without reference to another, the amendments are to be harmonized, if possible, so that effect may be given to each. If the amendments are substantively irreconcilable, the latest in date of enactment prevails. The fact that a later amendment restates language deleted by an earlier amendment, or fails to include language inserted by an earlier amendment, does not of itself make the amendments irreconcilable. Amendments are irreconcilable only when changes made by each cannot reasonably be put into simultaneous operation.
