Ohio Rev. Code § 305.32
Any referendum petition may be presented in separate petition papers, but each petition paper shall contain a full and correct copy of the title and text of the resolution or rule sought to be referred. Referendum petitions shall be governed by the rules of section 3501.38 of the Revised Code. In determining the validity of any such petition, all signatures which are found to be irregular shall be rejected, but no petition shall be declared invalid in its entirety when one or more signatures are found to be invalid except when the number of valid signatures is found to be less than the total number required by section 305.31 of the Revised Code.
The petitions and signatures upon such petitions shall be prima-facie presumed to be in all respects sufficient. No resolution submitted to the electors of any county, and receiving an affirmative majority of the votes cast thereon, shall be held ineffective or void on account of the insufficiency of the petitions by which such submission of the resolution was procured, nor shall the rejection, by a majority of the votes cast thereon, of any resolution submitted to the electors of such county, be held invalid for such insufficiency. No rule submitted to the electors of the county, and receiving a majority of the votes cast against repeal, shall be held invalid or void on account of the insufficiency of the petitions by which such submission was procured, nor shall the repeal, by approval of a majority voting for repeal, be held invalid for such insufficiency.
Resolutions receiving an affirmative majority of the votes cast thereon, shall become effective on the first day of the month following certification by the board of elections of the official vote on such question.
