Ohio Rev. Code § 109.365: Information obtained is privileged.

Information obtained by the attorney general pursuant to his investigation to determine whether to defend an officer or employee is privileged and is not admissible as evidence against the officer or employee in any legal action or proceeding and no reference to the information may be made in any trial or hearing. The decision of the attorney general to defend or not defend an officer or employee is not admissible as evidence in any trial or hearing. This section does not apply to any trial or hearing to determine the right of an officer or employee to reimbursement pursuant to section 109.364 of the Revised Code or to any trial or hearing held as a result of an action filed pursuant to division (F) of section 9.87 of the Revised Code.
