State v. Sorbonne, 506 P.3d 545

Background:

On June 20, 2018, Robert Sorbonne pointed a handgun at his father, chambered a round, and threatened to kill him after an argument; Sorbonne was charged with threatening with or using a dangerous weapon in a quarrel (misdemeanor).
Sorbonne claimed self-defense, proffering testimony that his father had a history of violent behavior; the trial court admitted some prior-violence evidence but excluded other testimony (including a DCFS “finding” question and certain family witnesses about specific incidents).
The district court found Sorbonne’s threat was “not necessary or reasonable” and convicted him; Sorbonne appealed.
The Utah Court of Appeals affirmed, applying Utah precedent requiring that a defendant’s belief be “objectively reasonable,” and held Sorbonne failed to show error in evidentiary rulings or in the standard applied.
The Utah Supreme Court granted certiorari to address whether the court of appeals erred in requiring an objective standard of reasonableness and to clarify the role of prior-abuse evidence in the self-defense inquiry.
The Utah Supreme Court held the statutory standard encompasses both a subjective belief and an objective-reasonableness component, that prior violent acts and patterns of abuse are relevant factors, and affirmed the court of appeals because Sorbonne identified no reversible error.

Issues:

Issue	Sorbonne's Argument	State's Argument	Held
Whether Utah requires an objective standard of reasonableness for self-defense	Utah should adopt a "modified objective" or subjective standard (analogous to battered-person context); the inquiry should focus on whether the fear was genuine	Utah precedent requires that the defendant’s belief be objectively reasonable under the circumstances	The statute includes both subjective and objective components: the defendant must actually believe force was necessary and that belief must be objectively reasonable; prior-abuse evidence is a relevant factor; affirmed
Whether exclusion of certain testimony about father’s prior violence (DCFS finding, specific incidents, road rage) was erroneous	Excluded evidence was relevant to reasonableness and should have been admitted	The court admitted significant prior-violence evidence; excluded material was either not ruled on below, lacked proper foundation, or was not shown to be known by Sorbonne	Court of Appeals did not err; Sorbonne failed to show abuse of discretion or preservation of some evidentiary claims; affirmed
Whether trial court applied a deadly-force standard instead of a lower standard for threats	Trial court allegedly applied a higher (deadly-force) standard rather than the standard for non-deadly threats	Trial court expressly found Sorbonne’s conduct unreasonable under either characterization of force	No preserved reversible error—the district court found the conduct unreasonable regardless of which standard applied; affirmed
Whether the district court erred in burden/assessment of reasonableness (e.g., failure to place burden on prosecution)	Argued court concluded lack of reasonable belief without properly assigning burden to prosecution	No such claim was properly preserved or argued below	Not preserved or adequately briefed; not a basis for reversal
