Salt Lake City v. Miles, 342 P.3d 212

Background

Wade John Miles, a Category II restricted person, was arrested after an encounter at a Salt Lake City light-rail platform during which he allegedly threatened a supervisor and had a folding pocketknife in a shopping cart beside him.
The knife: ~3.5" blade, one-inch serration, thumb stud for one-hand opening and a lock; officer testified it could cause serious injury but also had lawful uses and would only injure if someone intended to use it as a weapon.
Miles was charged with, inter alia, possession of a dangerous weapon by a restricted person under Utah Code § 76-10-503(3) (2011); jury convicted on the dangerous-weapon count but acquitted on other charges.
Miles appealed, arguing the statutory definition of “dangerous weapon” (Utah Code § 76-10-501(6)) bars reliance on intended use when the item is a knife or otherwise not commonly known as a dangerous weapon; he argued Salt Lake City failed to prove actual use.
The court of appeals held intended use could be considered for knives and affirmed the conviction (relying in part on Miles’s verbal threats). The Utah Supreme Court granted certiorari.

Issues

Issue	Plaintiff's Argument (Miles)	Defendant's Argument (Salt Lake City)	Held
Proper interpretation of Utah Code § 76-10-501(6): whether "intended use" may be considered for knives or items not commonly known as dangerous weapons	Subsection (b) lists the exclusive factors for knives/like items; those factors require actual use or wounds, so intended use may not be relied on	Subsection (a)'s reference to "intended use" applies generally; intended use may show an item is a dangerous weapon even if not actually used	The court held subsection (b)'s four factors are the exclusive considerations for knives/objects not commonly known as dangerous weapons; intended use is not admissible for those items
Sufficiency of evidence that Miles's pocketknife was a "dangerous weapon" under § 76-10-501(6)(b)	Because the knife was not actually used and produced no wounds, evidence was insufficient under the four statutory factors	The jury could infer weapon status from characteristics plus Miles's threats and proximity of the knife	The court held the evidence insufficient: the knife lacked distinctive weapon-like character, produced no wounds, was not actually used, and had lawful uses, so conviction reversed
Effect of reading subsection (b) as exclusive on the statute's possession offense	(implicit) This reading does not eliminate possession liability for items commonly known as dangerous weapons; knives require factor analysis	Argued exclusive focus on actual use would nullify the possession offense for knives/objects with lawful uses	Court rejected the nullification argument: items commonly known as dangerous weapons still fall under subsection (a); subsection (b) governs items not commonly known as weapons
Proper role of subsection (b) factors (definitional vs. evidentiary)	Factors are the exclusive definitional test for knives/like objects; focus is on actual use and wounds	Court of appeals treated factors as evidentiary and allowed intended-use evidence	Supreme Court held subsection (b) prescribes the exclusive statutory considerations for knives/objects not commonly known as dangerous weapons (emphasis on actual use/wounds)
