Ohio Revised Code Title LV. Roads Highways Bridges § 5505.20

Should a member of the state highway patrol retirement system cease to be an employee of the state highway patrol, for any reason, except retirement or death, the member shall thereupon cease to be a member of the retirement system. A member who is paid the member's accumulated contributions under section 5505.19 of the Revised Code shall forfeit the member's total service credit at that time. Should the former member return to the employ of the state highway patrol, the former member shall again become a member. When said re-employment occurs the total service credit last forfeited by the member shall be restored to the member's credit, provided the member pays into the employees' savings fund the amount, if any, the member withdrew therefrom, together with such compound interest as the board may require from the date of withdrawal to the date of repayment. The member may choose to purchase only part of such credit in any one payment, subject to board rules. The return of accumulated contributions shall be made according to such rules as the board shall from time to time adopt.
