Ohio Rev. Code Ann. § 2937.13

In entering a finding, pursuant to section 2937.12 of the Revised Code, the court, while weighing credibility of witnesses, shall not be required to pass on the weight of the evidence and any finding requiring accused to stand trial on any charge shall be based solely on the presence of substantial credible evidence thereof. No appeal shall lie from such decision nor shall the discharge of defendant be a bar to further prosecution by indictment or otherwise.
