To be valid, a jury waiver must be made "in open court"
Today the Second District Court of Appeals reversed a conviction for felonious assault because the defendant waived his right to a jury trial in the judge's chambers and not in open court. Jury waivers are addressed by Criminal Rule 23(A), Revised Code Section 2945.05, and the Ohio Supreme Court decision in State v. Lomax, 114 Ohio St.3d 350, 2007-Ohio-4277.
Everything about the waiver was valid in this case except it was not done "in open court." Today's Second District decision in State v. Burnside, 2010-Ohio-1235, indicates that all the trial judge had to do was have the defendant acknowledge the jury waiver in open court before conducting the bench trial. But no acknowledgment was sought by the trial court and so Burnside's conviction was reversed and he gets another bite at the apple (although whether this is a good thing for Burnside remains to be seen since he received probation (community control sanctions) after his bench trial conviction for felonious assault - a second degree felony that could result in a prison term of up to eight years).
