Aggravated Assault Under the MPC

Introduction

Model Penal Code § 211.1 treats assault as a ladder of offenses rather than a single crime.¹ Subsection (1) occupies the bottom rung, simple assault, which reaches an actor who attempts to cause bodily injury and an actor who culpably inflicts it.² The reason for a ladder becomes clear when you compare a shove that leaves a bruise with a stabbing that punctures a lung. Both involve one person hurting another, yet a single penalty cannot serve both: set it low enough for the shove and the stabbing is badly under-punished, and set it high enough for the stabbing and the shove is badly over-punished. Subsection (2) answers that problem by lifting assault into felony territory when the harm sought or caused is grave or when the actor uses a deadly weapon.³

Subsection (2) declares a person guilty of aggravated assault when the conduct fits one of two paragraphs.⁴ Paragraph (a) aggravates by the severity of the harm and the actor's attitude toward human life: it covers an attempt to cause serious bodily injury, and it covers actually causing such injury purposely, knowingly, or recklessly under circumstances manifesting extreme indifference to the value of human life.⁵ Paragraph (b) aggravates by the means employed, reaching an actor who attempts to cause, or purposely or knowingly causes, bodily injury with a deadly weapon.⁶ The two paragraphs therefore ask different questions. Paragraph (a) looks at how bad the injury was or was meant to be and at how callous the actor was about life, while paragraph (b) looks at the instrument. Because the weapon supplies the gravity, the injury required under paragraph (b) is only ordinary bodily injury, and no showing of serious bodily injury is needed.

That architecture dictates the first analytical step. The analysis begins by confirming that there is an assault at all, meaning an attempt to injure or a culpable infliction of injury, because each aggravator intensifies an underlying offense and cannot replace it. A weapon in the actor's hand or a grave injury in the hospital record does not by itself supply the culpable attempt or infliction that makes the conduct an assault in the first place. Only once that baseline is established does the next question arise: whether the facts supply an aggravator, either grave harm sought or caused with the required attitude toward life under paragraph (a), or a deadly weapon under paragraph (b). This chapter follows that order, then turns to the meaning of serious bodily injury, each paragraph in turn, and the way the grades fit together. It begins with the simple-assault baseline that subsection (2) escalates.
