In State v. Pless (1996), 74 Ohio St.3d 333, 1996 Ohio 102, 658 N.E.2d 766, the Supreme Court of Ohio held that "in a criminal case where the defendant elects to waive the right to trial by jury, R.C. 2945.05 mandates that the waiver must be in writing, signed by the defendant, filed in the criminal action and made part of the record thereof. Absent strict compliance with the requirements of R.C. 2945.05, a trial court lacks jurisdiction to try the defendant without a jury." State v. Pless (1996), 74 Ohio St.3d at paragraph one of the syllabus.
