29 Cal.App.5th 314
Cal. Ct. App.2018Background
- Intoxicated defendant Nathaniel Stutelberg got into an altercation outside a bar and used a box cutter during separate encounters with Michelle S., Chris L., and Missael O.
- Michelle was cut across the back of her head, required stitches, and had lingering nerve damage; Chris was swung at but not injured; Missael testified he was jabbed but the jury acquitted on charges involving him.
- Charged counts included mayhem (count 1) and attempted mayhem/assault counts; the jury convicted Stutelberg of mayhem (lesser included) as to Michelle with a deadly-weapon enhancement and of assault with a deadly weapon as to Chris, acquitting on other counts.
- Trial court instructed the jury with CALCRIM language treating a "deadly weapon" as either inherently deadly or deadly by use; a box cutter is not an inherently deadly weapon as a matter of law.
- The sole appellate issue was whether the instruction’s inclusion of the "inherently deadly" theory was legal error and, if so, whether that error was harmless.
- Court concluded the instruction was legal error, applied Chapman harmless-error review, affirmed as to Michelle (count 1) but reversed as to Chris (count 3) because prejudice could not be dismissed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether instructing that a weapon may be "inherently deadly" when a box cutter is involved was improper | Instructional error was factual (an inapplicable theory) and harmless | Instructional error was legal (incorrect statement of law) requiring Chapman review | Court: legal error (jury could misinterpret term); Chapman applies |
| Standard of prejudice to apply when a legal instructional error defines an element incorrectly | Chapman standard suffices; reversal not required absent showing error affected verdict | Requires heightened showing (per Aledamat) that jurors relied on invalid theory | Court: apply traditional Chapman harmless-beyond-a-reasonable-doubt standard |
| Prejudice as to mayhem enhancement (Michelle) | Evidence shows box cutter used in manner likely to cause great bodily injury; error harmless | Error could have misled jury but facts establish weapon-by-use regardless | Harmless beyond a reasonable doubt; conviction and enhancement affirmed |
| Prejudice as to assault with deadly weapon (Chris) | Evidence (threat/flicking) still supports deadly-weapon finding | Instructional error likely influenced verdict where use was ambiguous | Reversal of count 3; cannot say error was harmless beyond a reasonable doubt |
