Ohio Rev. Code § 4112.056
Whenever the Ohio civil rights commission has reasonable cause to believe that any person or persons are engaged in a pattern or practice of resistance to a person or persons' full enjoyment of the rights granted by division (H) of section 4112.02 of the Revised Code, or that any group of persons has been denied any of the rights granted by that division and the denial raises an issue of public importance, the commission may refer the matter to the attorney general for commencement of a civil action in a court of common pleas. The attorney general may seek any preventive relief considered necessary to ensure the full enjoyment of the rights granted by that division, including a permanent or temporary injunction or temporary restraining order.
