The Culpability Baseline

The Culpability Baseline

Every crime has a physical side and a mental side. The physical side, the actus reus, is the forbidden conduct. The mental side, the mens rea, is the state of mind that must accompany that conduct, and although all crimes have the first, most but not all have the second.¹ The Model Penal Code gives the mental side a precise structure. Section 2.02(1) provides that, except as § 2.05 allows, a person is not guilty of an offense unless he acted purposely, knowingly, recklessly, or negligently, as the law may require, with respect to each material element of the offense.² A material element is a fact that the definition of the offense makes essential to guilt, and it may be an act, a surrounding circumstance, or a result.³ Because the requirement runs element by element, the prosecution cannot satisfy it with proof of a generally bad state of mind. For every fact that matters to guilt it must prove one of the four named mental states as to that fact, and the definition of the offense decides which one. This default is the culpability baseline, and strict liability is measured against it: an offense is strict as to an element when the baseline requirement has been lifted for that element.

The Code did not invent the idea that crimes need a guilty mind. It replaced the confusing vocabulary in which that idea had been expressed. Terms such as general intent, malice, wilfulness, and scienter had been used loosely and inconsistently, and one stated purpose of § 2.02 was to dispel the obscurity they produced.⁴ In their place the Code uses four defined modes of acting, which run from most to least culpable.⁵ An actor behaves purposely when it is the actor's conscious object to engage in the conduct or cause the result, knowingly when aware that the circumstance exists or that the result is practically certain to follow, and recklessly when aware of a substantial and unjustifiable risk and consciously disregarding it.⁶ An actor behaves negligently when the actor should be aware of such a risk, meaning that the failure to perceive it is a gross deviation from the care a reasonable person in the actor's situation would use.⁷ The first three modes depend on what the actor actually perceived, while negligence asks what the actor should have perceived. Even so, the demand for a substantial and unjustifiable risk and a gross deviation keeps Code negligence well above ordinary carelessness.

The baseline also answers the question of what happens when a legislature says nothing about mental state. Section 2.02(3) establishes a presumption that the culpability requirements apply to statutes silent on the point, so that an element with no stated culpability is established by purpose, knowledge, or recklessness.⁸ A receiving-stolen-property statute shows what turns on that presumption. A statute that punishes receiving property knowing it to be stolen demands subjective awareness; one that punishes receiving it with reason to know it was stolen sets an objective standard; and one that punishes receiving stolen property without any further words is, read literally, satisfied when the property is in fact stolen, even though the receiver neither knew nor reasonably could have known.⁹ Under the Code the third version is not read literally: the baseline fills the gap, and the legislature's silence does not count as a choice to dispense with fault. Students lose this issue when they treat silence about mental state as a legislature's quiet adoption of strict liability.

A second presumption governs statutes that do state a mental state. Section 2.02(4) presumes that a culpability requirement applies to all of the offense's elements, not only to the element that sits nearest the word.¹⁰ Without that presumption, a word like knowingly could be read to protect the actor on the first element and leave the rest unguarded, which would bring back strict liability by an accident of grammar. Federal courts read statutes the same way. In Flores-Figueroa v. United States (2009) the Court held that the government had to prove the defendant knew the Social Security number on the card he used belonged to someone else, because courts ordinarily read a phrase that introduces a crime's elements with the word knowingly as applying that word to each element.

An offense that states its mental state expressly shows the baseline operating without friction. The Code's own offense of aiding or soliciting suicide, § 210.5(2), reaches a person who purposely aids or solicits another to commit suicide, and it is a second-degree felony if the conduct causes a suicide or an attempt and a misdemeanor otherwise.¹¹ The definition names purpose as the mental state for the aiding, so nothing is displaced and the prosecution must prove that purpose.

A constitutional rule stands beneath the statutory one. Due process protects against conviction except on proof beyond a reasonable doubt of every fact necessary to constitute the crime, so the prosecution must prove each mental-state element an offense contains rather than presume it.¹² In Sandstrom v. Montana the Court applied that rule to an instruction that jurors may presume a person intends the ordinary consequences of voluntary acts, and held the instruction unconstitutional because jurors could have read it as conclusive or as shifting to the defendant the burden on intent.¹³ The two rules fit together. A legislature chooses an offense's elements, the Code's baseline supplies a mental-state element unless the legislature plainly provides otherwise, and once the elements exist the State must prove each of them.¹⁴ Substance controls over labels here: in Mullaney v. Wilbur the Court refused to let Maine avoid the reasonable-doubt requirement for a fact bearing on the degree of culpability by treating that fact as relevant only to punishment.¹⁵

Against this baseline, § 2.05 stands out as the one place where the Code lets fault drop away. Its opening clause provides that the culpability requirements of §§ 2.01 and 2.02 do not apply to the categories it goes on to list.¹⁶ In United States v. Cordoba-Hincapie the court surveyed the Code's culpability provisions, described § 2.05 as the Code's sole exception to its insistence on mens rea, and called that exception a narrow one.¹⁷ The drafters themselves characterized § 2.05 as "a frontal attack on absolute or strict liability."¹⁸ The court also emphasized that, for offenses defined outside the Code, a legislative intent to impose strict liability must "plainly appear."¹⁹ That standard fits the structure of the baseline. Because silence is already read to require fault, a court cannot infer absolute liability from missing mental-state words, and a legislature that wants absolute liability has to say so in a way that puts the choice in the open where it can be debated.

The text of § 2.05(1)(b) reaches absolute liability for an offense or with respect to any single material element of it, so the baseline can be lifted for one element while it still governs the rest.²⁰

Because the baseline is lifted element by element, three labels describe how far strict liability reaches. An offense is pure strict liability when no element depends on the actor's awareness, impure when awareness is required for some elements but not others, and substantive when morally blameless persons can commit it.²¹ The bartender offense above is both impure and substantive: awareness matters for the alcohol element but not the age element, and a careful seller who is deceived is blameless. Pure strict liability is unusual, since most descriptions of conduct imply some awareness of what the actor is doing, and the controversial cases usually combine impure strict liability with substantive strict liability.²²

The reason for the baseline has two parts that work differently. The first concerns what a conviction does. The drafters put it this way: "Crime does and should mean condemnation and no court should have to pass that judgment unless it can declare that the defendant's act was culpable."²³ From the preventive side, punishment works by threatening consequences for choices, and conduct unaccompanied by awareness of the facts that make it criminal does not mark the actor as someone who needs to be deterred, incapacitated, or reformed.²⁴ A person who does not know the buyer is a minor cannot use the threat of punishment to choose differently, so convicting that person adds cost without changing anyone's conduct. From the retributive side, the conviction brands the actor with stigma, and without awareness that stigma falls on someone who is not morally blameworthy.²⁵

The second part concerns the shape of the four-mode ladder. Its lowest rung, negligence, still ties liability to a failure the actor could have avoided. The drafters reasoned that people who know a conviction may follow from inadvertently creating improper risk have an added motive to take care before acting, and that moral defect can fairly be imputed to someone who acts out of insensitivity to the interests of others.²⁶ A properly calibrated negligence standard can therefore induce caution without reaching the person who was truly faultless, whereas absolute liability reaches that person too. That contrast explains why the Code accepts negligence and treats strict liability as an exception needing justification, and it sets up the policy dispute taken up later in this chapter. Given a default this strong, the question becomes when the Code lets absolute liability in at all, and the next section answers it by taking § 2.05(1) apart.
