State v. Montgomery, 2015 Ohio 4652

Defendant William Montgomery was charged with misdemeanor assault after a fight at his home with Samuel Seal; bench trial resulted in conviction and a 180-day jail sentence (170 days suspended).
State witnesses (Seal and his wife Casey) testified Seal knocked, the door opened, he walked in, and Montgomery immediately and violently attacked him, with a third party (Anspach) later holding Seal in the snow.
Defense witnesses (Montgomery and his wife) testified Seal forcibly entered a locked door, was abusive toward Montgomery’s wife, Montgomery told Seal to leave, Seal grabbed and shoved Montgomery, and Anspach pulled Seal off and ejected him from the home.
Trial court rejected self-defense, finding Montgomery used excessive/unnecessary force and convicted him of assault under R.C. 2903.13(A).
On appeal, Montgomery argued (1) the conviction was against the manifest weight of the evidence and (2) the trial court applied an improper "excessive force" standard contrary to the castle-doctrine presumption in R.C. 2901.05(B).
The Twelfth District held the trial court used the correct legal standard (the castle doctrine presumes reasonableness but the State may rebut by showing force was not reasonably necessary) but reversed the conviction as against the manifest weight because the State failed to rebut the self-defense presumption; the State’s witnesses were found implausible in several respects.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the trial court applied the correct legal standard for self-defense under the castle doctrine	State: court correctly found Montgomery’s force excessive, negating the presumption of self-defense	Montgomery: R.C. 2901.05(B) presumptively permits any defensive force against an unlawful intruder; court erred applying an "excessive force" test	Court: No error — R.C. 2901.05(B) creates a rebuttable presumption of reasonable force but State may rebut by showing force was not reasonably necessary
Whether Montgomery’s conviction is against the manifest weight of the evidence	State: evidence (Seal/Casey testimony) supports that Montgomery used excessive, unprovoked force	Montgomery: State’s testimony is implausible; he acted in self-defense and the presumption was unrebutted	Court: Reversed — State failed to rebut the self-defense presumption; witness testimony was implausible and insufficient to overcome presumption
