Ohio Rev. Code § 504.17
The establishment of a limited home rule government does not affect any act done, ratified, or affirmed, or any contract or other right or obligation accrued or established, or any action, prosecution, or proceeding, civil or criminal, pending at the time this change in government takes effect. The establishment of a limited home rule government does not affect any cause of action, prosecutions, or proceedings existing at the time it takes effect. Rights that attach to any act of the township, and actions, prosecutions, or proceedings may be prosecuted and continued, or instituted and prosecuted against, by, or before the department having jurisdiction or power of the subject matter to which the right, action, prosecution, or proceedings pertain.
All rules and orders lawfully promulgated prior to the establishment of a limited home rule government in the township continue in force and effect until amended or rescinded in accordance with this chapter.
