Article 210 — Criminal Homicide

MPC § 210.3: Manslaughter

Quick Answer

What does Manslaughter (Model Penal Code) provide?

Section 210.3 defines manslaughter under the MPC. Criminal homicide constitutes manslaughter when it is committed recklessly, or when a homicide that would otherwise be murder is committed under the influence of extreme mental or emotional disturbance for which there is reasonable explanation or excuse. The reasonableness of the explanation or excuse is determined from the viewpoint of a person in the actor's situation under the circumstances as they believe them to be. Manslaughter is a felony of the second degree.

Summary

The extreme mental or emotional disturbance (EMED) provision is the MPC's replacement for the common law's voluntary manslaughter heat of passion doctrine. It is significantly broader in several respects. It does not require a specific "adequate provocation" from a legally recognized category — any extreme emotional disturbance with a reasonable explanation suffices. It eliminates the requirement that the provocation come from the victim. It drops the cooling-off time limitation — even a long-simmering emotional disturbance can qualify if there is a reasonable explanation. And it uses a partially subjective standard: the reasonableness of the explanation is judged from the viewpoint of a "person in the actor's situation."

The phrase "the actor's situation" has been subject to significant interpretive debate. How many of the defendant's personal characteristics should be attributed to the hypothetical reasonable person? The MPC drafters left this deliberately flexible, but courts have struggled with whether to include characteristics like the defendant's cultural background, history of abuse, temperament, or mental health conditions. The reckless manslaughter prong is more straightforward — it applies to any reckless killing that does not rise to the level of extreme indifference required for murder.

Key Provisions

6 essential provisions of § 210.3

Manslaughter: reckless homicide, or murder reduced by extreme mental or emotional disturbance (EMED)

EMED must have a reasonable explanation or excuse, judged from the viewpoint of a person in the actor's situation

No requirement of legally adequate provocation — any extreme emotional disturbance with reasonable explanation suffices

No cooling-off time limitation — long-simmering disturbance can qualify

Provocation need not come from the victim

Manslaughter is a felony of the second degree

MPC vs. Common Law

How the MPC approach to manslaughter differs from common law

The common law heat of passion doctrine was much more restrictive. It required: (1) legally adequate provocation (traditionally limited to categories like discovering a spouse in adultery, mutual combat, assault and battery, or illegal arrest — mere words were typically insufficient); (2) actual heat of passion (the defendant was actually provoked); (3) no adequate cooling-off time; and (4) a causal connection between the provocation and the killing. The MPC's EMED doctrine eliminates the categorical approach to provocation, removes the cooling-off requirement, and uses a more flexible reasonableness standard. This allows for a wider range of mitigating circumstances, including cumulative psychological trauma (e.g., battered spouse situations) that would not fit neatly into common law provocation categories. However, critics argue the MPC standard is too broad and may allow cultural or personal biases to serve as "reasonable explanations" for violence.

Exam Relevance

How § 210.3 appears on criminal law exams

Manslaughter is tested alongside murder in virtually every homicide question. Key exam issues: (1) EMED vs. heat of passion — a fact pattern involving a killing after emotional disturbance will yield different results under MPC vs. common law, especially if there is a cooling-off period, if words alone provoked the defendant, or if the provocation did not come from the victim; (2) The meaning of "the actor's situation" — what characteristics of the defendant should the jury consider when evaluating the reasonableness of the explanation? (3) The line between reckless manslaughter and extreme indifference murder — both involve conscious disregard of risk, so the difference is one of degree; (4) The line between reckless manslaughter and negligent homicide — recklessness requires conscious awareness of risk, while negligence requires only that the actor should have been aware. Students should practice articulating why the same killing might be graded differently under MPC vs. common law.
