Ohio Const. art. II, § 35

For the purpose of providing compensation to workmen and their dependents, for death, injuries or occupational disease, occasioned in the course of such workmen's employment, laws may be passed establishing a state fund to be created by compulsory contribution thereto by employers, and administered by the state, determining the terms and conditions upon which payment shall be made therefrom. Such compensation shall be in lieu of all other rights to compensation, or damages, for such death, injuries, or occupational disease, and any employer who pays the premium or compensation provided by law, passed in accordance herewith, shall not be liable to respond in damages at common law or by statute for such death, injuries or occupational disease. Laws may be passed establishing a board which may be empowered to classify all occupations, according to their degree of hazard, to fix rates of contribution to such fund according to such classification, and to collect, administer and distribute such fund, and to determine all right of claimants thereto. Such board shall set aside as a separate fund such proportion of the contributions paid by employers as in its judgment may be necessary, not to exceed one per centum thereof in any year, and so as to equalize, insofar as possible, the burden thereof, to be expended by such board in such manner as may be provided by law for the investigation and prevention of industrial accidents and diseases. Such board shall have full power and authority to hear and determine whether or not an injury, disease or death resulted because of the failure of the employer to comply with any specific requirement for the protection of the lives, health or safety of employes, enacted by the General Assembly or in the form of an order adopted by such board, and its decision shall be final; and for the purpose of such investigations and inquiries it may appoint referees. When it is found, upon hearing, that an injury, disease or death resulted because of such failure by the employer, such amount as shall be found to be just, not greater than fifty nor less than fifteen per centum of the maximum award established by law, shall be added by the board, to the amount of the compensation that may be awarded on account of such injury, disease, or death, and paid in like manner as other awards; and, if such compensation is paid from the state fund, the premium of such employer shall be increased in such amount, covering such period of time as may be fixed, as will recoup the state fund in the amount of such additional award, notwithstanding any and all other provisions in this constitution.
