In these consolidated appeals, we are faced with the immediate question of what jury instructions for the crime of manslaughter are appropriate where a person *32 dies as a result of bare-fisted blows to the face. Like an unraveling string, this inquiry has led to and necessitated a more general examination of the law of manslaughter and particularly its division in our jurisdiction into “voluntary” and “involuntary” components. 1 In No. 87-249, Joseph Pinkney died after appellant Comber struck him either once or twice in the face with his bare fist. In No. 89-31, Ger-iel Butler died after appellant Hayward, in two incidents separated by five to twenty-five minutes, punched him twice in the face. Both men were indicted for second-degree murder in violation of D.C.Code § 22-2403 (1989) and were tried before juries. In each case, the jury acquitted the defendant of second-degree murder but returned a guilty verdict on the lesser-included charge of voluntary manslaughter. Id. § 22-2405. Both appellants challenge the voluntary manslaughter instructions upon which the juries based their verdicts. They also raise challenges pertaining to involuntary manslaughter instructions: appellant Hayward claims the trial court erred in refusing to give such an instruction, while appellant Comber claims the involuntary manslaughter instruction in his case was improper. Because we agree with these contentions of instructional error, we reverse and remand for new trials.
I. THE HOMICIDES
A. Appellant Comber
Gilbert Comber apparently did not approve of his sister Mary Comber’s relationship with Joseph Pinkney. On February 3, 1986, Pinkney, Mary’s former boyfriend, came to the Comber residence to visit her. When Ms. Comber attempted to leave the house to speak with Pinkney, appellant intervened and would not permit her to leave. Appellant and Ms. Comber began to struggle, and appellant hit her. After Pinkney saw this, he and appellant began to argue. However, the two men were seрarated, and Pinkney left the area before any further violence erupted. During the afternoon of February 4, Pinkney and Mary Comber arrived at the Comber residence after having spent the day together. The two had decided to get married, and had been drinking with friends. A friend of the Combers mistakenly told appellant that Pinkney and Ms. Comber had secretly been married. Saying he was going to get his sister, appellant went out to the alley where Ms. Comber and Mr. Pinkney had parked their car. Witnesses differed as to what happened next. All agreed, however, that Comber, who was substantially smaller by weight than Pinkney, punched Pinkney either once or twice in the face. Pinkney, who was extremely intoxicated at the time of death, fell down, and appellant returned to his house. Though Pinkney was still conscious after being knocked to the ground, he later lapsed into unconsciousness; by the time police arrived, he appeared to be dead. The medical examiner who performed an autopsy on Pinkney’s body testified that the cause of death was one or more extremely forceful blows to the face which caused subarachnoid brain hemorrhaging, or bleeding in the part of the brain which controls the heartbeat and respiration. According to the medical examiner, there was no evidence that Pink-ney’s death resulted from his head striking the pavement when he fell. Appellant Comber testified that he struck Mr. Pink-ney only once, and in self-defense. He stated that Pinkney took a swing at him when he tried to get his sister to return to *33 the house with him, and that he never intended to kill Pinkney.
B. Appellant Hayward
In the early morning hours of November 27, 1987, appellant Hayward struck Geriel Butler in the jaw. Butler fell into the street, hit his head, and lost consciousness. He soon regained consciousness, stood up, and walked away. Witnesses disagreed about precisely what happened next, but they all agreed that appellant Hayward and Butler encountered one another again a short time later near a van from which a vendor sold clothes. Appellant Hayward again punched Butler in the jaw. As Butler fell to the ground, the back of his head struck the concrete. Butler lost consciousness and died later that morning at D.C. General Hospital. The medical examiner who performed an autopsy bn Butler’s body testified that the cause of death was swelling and herniation of the brain, caused by the impact to the back of Butler’s head when he fell and hit the ground.
Appellant Hayward testified that he struck Butler in self-defense. He stated that Butler approached him and asked to purchase drugs. After being rebuffed, Butler hollered at appellant Hayward and approached him with his fist balled up. Thinking Butler was about to hit him, appellant Hayward struck Butler. Hayward stated that he then walked across the street to the clothes van, where a short time later Butler again approached, shaking his fist and seeking retribution for the earlier incident. Thinking that Butler would strike him, Hayward again hit Butler, who fell, hitting his head on the concrete.
II. THE INSTRUCTIONS
A. Appellant Comber
After extended discussions, the trial court in Comber’s case decided to instruct the jury on both the lesser-included offenses of voluntary manslaughter and involuntary manslaughter. As to each offense, the judge modified the District’s standard jury instructions. The court gave the following instructions on voluntary manslaughter:
Now, let me read to you the jury instructions on voluntary manslaughter. Manslaughter is the unlawful killing of a human being without malice. Manslaughter is committed when a human being is killed unlawfully in the sudden heat of passion caused by adequate provocation as the Court has already defined those terms for you. The elements of this offense, each of which the Government must prove beyond a reasonable doubt are as follows:
One: That the defendant inflicted an injury or injuries upon the deceased from which the deceаsed died.
Two: That the killing was committed without legal justification or excuse.
And three: That the defendant intended to commit the acts which inflicted the injury or injuries.
To establish the first essential element it is necessary that the defendant have inflicted an injury or injuries upon the deceased and that the deceased died as a result of such injury or injuries.
To establish the second essential element of the offense it is necessary that you find the defendant guilty beyond a reasonable doubt, that the defendant did not act in self-defense.
And to establish the third essential element it is necessary that you find that the defendant intended to commit the act which inflicted the injury or injuries upon the deceased. 2
(Emphasis added.)
On the crime of involuntary manslaughter, the trial court instructed the jury as follows:
*34 [IJnvoluntary manslaughter is the unlawful killing of a human being without malice. It may be a killing committed without a specific intent to kill or even without the specific intent to inflict injury which causes death. One may be found guilty of involuntary manslaughter if you find that his conduct was so reckless that it involved extreme danger of death or serious bodily harm and was a gross deviation from the standard of conduct a reasonable person should have observed under the circumstances.
Now, the elements of this offense, each of which the Government must prove beyond a reasonable doubt, are as follows:
One: That the defendant inflicted an injury upon the deceased from which the deceased died.
Two: That the injury was a result of a course of conduct involving extreme danger of death or serious bodily injury.
Three: That although the conduct was not intentional it amounted to recklessness and was a gross deviation from the standard of conduct that a reasonable person should have observed.
And four: That the killing was committed without legal justification or excuse. 3
(Emphasis added.)
According to these instructions, the essential difference between voluntary and involuntary manslaughter lies in whether or not the defendant intentionally committed the act that caused death. In effect, the court instructed the jury that if Comber intentionally punched Pinkney in the face, the jury should find him guilty of voluntary manslaughter. On the other hand, if Comber punched Pinkney only accidentally, and the unintentional punch rose to the requisite level of recklessness, then the jury should find him guilty of involuntary manslaughter.
B. Appellant Hayward
Hayward requested instructions on both voluntary and involuntary manslaughter. The trial court agreed to instruct the jury on voluntary manslaughter, and gave the jury the following charge:
Voluntary manslaughter ... is the unlawful killing of a human being without malice. The essential elements of the offense of voluntary manslaughter, each of which the Government must prove beyond a reasonable doubt are:
One, that the defendant inflicted an injury or injuries upon the deceased from which the deceased died;
[A]nd, two, that the killing was committed without legal justification or excuse.
To establish the first essential element of that offense, it is as I have told you necessary that the defendant have inflicted an injury or injuries. With regard to the second element of that offense, it is necessary that the killing or homicide have been committed without legal justification or excuse.
Justifiable homicide is the necessary killing of another person in the performance of a legal duty or where the person who kills not being himself at fault has the legal right to kill. Excusable homicide occurs where the person who kills although himself at fault had the legal *35 right so to kill or where the killing was the accidental result of a lawful act done in a lawful manner. 4
In response to the appellant’s request for an involuntary manslaughter instruction, however, the trial court declared that Butler’s killing “wasn’t ... a result of recklessness.” Accordingly, the court refused to give such an instruction.
III. THE CRIME OF MANSLAUGHTER
A. Historical background
Although D.C.Code § 22-2405 (1989) establishes the penalty for manslaughter, “there is no statutory definition of manslaughter in the District of Columbia.”
United States v. Bradford,
1. The division of criminal homicide into murder and manslaughter
“What we now know as murder and manslaughter constituted just one offense under the common law of England.” R. Perkins & R. Boyce, Criminal Law 125 (3d ed. 1982). At the turn of the sixteenth century, all homicides, with the exception of accidental homicides, homicides committed in self-defense, or homicides committed “in the enforcement of justice,” “were deemed unlawful and were punished by death.”
Mullaney v. Wilbur,
Perhaps because of concern about “the accretion of ecclesiastic jurisdiction at the expense of the secular,”
Mullaney v. Wilbur, supra,
led to the division of criminal homicides into murder, which retained its status as a capital crime, and the lesser offense of manslaughter. The courts defined murder in terms of the evolving concept of “malice aforethought” and treated manslaughter as a residual category for all other criminal homicides.
Model Penal Code § 210.3 comment 1, at 44 (Official Draft and Revised Comments 1980) (footnotes omitted). See also 3 J. Stephen, supra, at 45.
Thus, manslaughter, “[i]n its classic formulation ... consisted of homicide without malice aforethought on the one hand and without justification or excuse on the other.” Model Penal Code,
supra,
§ 210.3 comment 1, at 44. This definition has been adopted in the District of Columbia.
See Morgan v. United States,
2. The division of manslaughter into voluntary and involuntary manslaughter
The broad and undifferentiated early definition of manslaughter created pres
*37
sure for refinement. In the same way that the early common law concept of unlawful homicide had evolved into murder and manslaughter, so too did manslaughter divide into separate categories of voluntary and involuntary manslaughter, depending on the type of conduct involved. 2 W. LaFave & A. SCOTT,
supra
note 6, § 7.9, at 251;
id.
§ 7.12, at 276-77. The distinction between the two varieties of manslaughter was noted by Blackstone as early as 1769.
See
4 W. Blackstone, Commentaries *191-93 (originally published 1769).
7
Initially, the distinction between voluntary and involuntary manslaughter was deemed “purely ... factual,” in that “the punishment [was] the same for both.” R. Perkins & R. Boyce,
supra,
at 83. At least until 1975, this tradition was reflected in the District of Columbia, where the punishment for manslaughter was prescribed by a single statute which made no distinction between voluntary and involuntary manslaughter,
see
D.C.Code § 22-2405, and where “it ha[d] not been the practice to charge [voluntary and involuntary manslaughter] separately and explicitly in indictments.”
Bradford, supra,
Both voluntary and involuntary manslaughter may still be accurately defined as “homicide[s] without malice aforethought on the one hand and without justification or excuse on the other.” Model Penal Code, supra, § 210.3 comment 1, at 44. The two offenses are distinguishable by virtue of the perpetrator’s state of mind; specifically, the difference between the two offenses lies in the basis for concluding that the perpetrator acted without malice aforethought. As explained below, in all voluntary manslaughters, the perpetrator acts with a state of mind which, but for the presence of legally recognized mitigating circumstances, would constitute malice aforethought, as the phrase has been defined for purposes of second-degree murder. All involuntary manslaughters, in contrast, are killings in which the perpetrator’s state of mind, without any consideration of any issues of mitigation, would not constitute malice aforethought.
B. “Malice aforethought” for purposes of second-degree murder
Because of the relationship between voluntary manslaughter and murder, *38 an understanding of the scope of the offense of voluntary manslaughter requires an examination of the states of mind which would make an unlawful killing second-degree murder. At common law, an unjustified or unexcused homicide rose to the level of murder if it was committed with malice aforethought. R. Perkins & R. Boyoe, supra, at 57. This definition continues in effect in the District of Columbia. D.C. Code § 22-2403. 9
For purposes of second-degree murder, “malice aforethought” has evolved into “a term of art” embodying several distinct mental states.
Byrd, supra
note 9,
Whatever the original meaning of [the] phrase [malice aforethought], it became over time an “arbitrary symbol” used by judges to signify any of a number of mental states deemed sufficient to support liability for murder. Successive generations added new content to “malice aforethought” until it enсompassed a variety of mental attitudes bearing no predictable relation to the ordinary sense of the two words.
Model Penal Code,
supra,
§ 210.2 comment 1, at 14.
See also
2 W. Burdick, The Law op Crime § 448 at 160-61 (1946) (the phrase “malice aforethought” “is now a purely technical phrase, and is used to define the state of mind which must accompany murder”). Following the common law trend, this court has recognized that malice aforethought, in the District of Columbia, “denotes four types of murder, each accompanied by distinct mental states.”
Byrd, supra
note 9,
First, a killing is malicious where the perpetrator acts with the specific intent to kill.
See id.
at 1385;
Logan v. United States,
Although not all jurisdictions are in agreement on the matter,
see
2 W. La-Fave & A. Scott,
supra
note 6, § 7.4, at 200, in the District of Columbia, such depraved heart malice exists only where the perpetrator was subjectively aware that his or her conduct created an extreme risk of death or serious bodily injury, but engaged in that conduct nonetheless.
12
Under our formulation, malice “may be found ‘where conduct is reckless and wanton, and a gross deviation from a reasonable standard of care, or such a nature that a jury is warranted in inferring that the defendant was aware of a serious risk of death or serious bodily harm.’ ”
Logan, supra,
Historically, a fourth kind of malice existed when a killing occurred in the course of the intentional commission of a felony. Under this “felony-murder” rule, “[mjalice, an essential element of murder, is implied from the intentional cоmmission of the underlying felony even though the actual killing might be accidental.”
Byrd, supra
note 9,
C. Justification, excuse, and mitigation
Even where an individual kills with one of the four states of mind described above, the killing is not malicious if it is justified, excused,
16
or committed un
*41
der recognized circumstances of mitigation. Implicit in the notion of malice aforethought is “the absence of every sort of justification, excuse or mitigation.” R. Perkins & R. Boyoe,
supra,
at 75.
See also Thomas v. United States,
Unlike circumstances of justification or excuse, legally recognized mitigating factors do not constitute a total defense to a murder charge. Such circumstances may, however, serve to “reduc[e] the degree of criminality” of a homicide otherwise committed with an intent to kill, an intent to injure, or in conscious and wanton disregard of life.
Bradford, supra,
D. Voluntary manslaughter
In this jurisdiction, a homicide constitutes voluntary manslaughter where the perpetrator kills with a state of mind which, but for the presence of legally recognized mitigating circumstances, would render the killing murder.
See Bradford, supra,
The government agrees that homicides in which the perpetrator acts with a state of mind which, absent recognized mitigating circumstances, would render the killing murder constitute voluntary manslaughter. However, the government contends that voluntary manslaughter also encompasses another distinct category of killings, namely, homicides resulting when a defendant acts with the intent to cause any injury to or apply any force against the victim. Since a killing occurring under mitigating circumstances would rise to the level of voluntary manslaughter if the perpetrator acted with specific intent to cause serious bodily injury, the only killings included in the government’s proposed definition not already encompassed by the above-discussed definition are those resulting from an act committed with intent to cause non-serious injury but which result in death. For several reasons, we must disagree with the government’s assertion. *44 Firstly, it would result in the adoption of an expanded definition of voluntary manslaughter at odds with the gеnerally recognized common law understanding of that offense, as described above. Secondly, the government grounds its assertion in authority which does not markedly support its position. Thirdly, acceptance of the government’s position would collide with the apparently universal classification, in jurisdictions which divide manslaughter into its voluntary and involuntary forms, of killings following a simple assault as involuntary, rather than voluntary, manslaughter. Finally, the government’s position would brand a defendant as a “voluntary” killer where he acted with a mind free of any intent to kill or seriously wound and free of a degree of knowing recklessness making highly likely such a result. We think that both common law and authority make a death-oriented mental state the determinative dividing line between the two forms of manslaughter, which should re-fleet their differing connotations of culpability.
In support of its position that a killing is voluntary manslaughter whenever a death results from an act committed with the intent to apply any force against or inflict non-serious injury on the victim, the government invokes our opinion in
United States v. Bradford, supra,
We read Bradford as limiting the scope of voluntary manslaughter to killings where the perpetrator acts with a state of mind which, but for the presence of recognized mitigating factors, would render the killing malicious, and hence murder. The court expressly declared that “[killings classified as voluntary manslaughter would in fact be second degree murder but for the existence of circumstances that in some way mitigate malice.” Id. at 215 (emphasis added). Moreover, in the paragraph summarizing its discussion of voluntary manslaughter in Bradford, the court stated that voluntary manslaughter “could more accurately be said to be (1) an unlawful killing of a human being (2) with malice which has been mitigated by the presence of circumstances judicially recognized as reducing the degree of criminality.” Id. 24 Because a homicide resulting from an act committed with the intent to inflict only non-serious bodily injury would not be a killing with malice and would not constitute second-degree murder, such a killing could not constitute voluntary manslaughter as that offense was ultimately defined in Bradford. 25
Nor does authority from other jurisdictions cited by the government suggest a different conclusion. The government relies in part on the Alabama Supreme Court’s 1860 decision in
McManus v. State,
The government also seeks support from Wharton’s 1907 treatise on homicide. F. Wharton, The Law of Homicide (F. Bowlby 3d ed. 1907),
cited in Bradford, supra,
Finally, the government’s contention that a homicide in which there is any intent to injure or apply force against the victim should be deemed voluntary manslaughter collides with the apparently near-universal classification, in jurisdictions which divide manslaughter into its voluntary and involuntary forms, of killings following a simple assault as involuntary, rather than voluntary, manslaughter. This division is made clear in the
Bradford
opinion itself. Despite the fact that in both instances there is an intent to injure or apply force to the victim, the
Bradford
opinion listed death “following an assault [or] excessive correction of children by parents or teachers” as illustrations of
involuntary
manslaugh-ters. F. Wharton,
supra
at 215, at 339. Were the government’s interpretation correct, the
Bradford
court would have included killings resulting from an assault or excessive correction of children as examples of voluntary manslaughter. Similarly, Wharton’s treatise, upon which the government relies, also classifies killings resulting from assaults, in which there was clearly intent to inflict some, but not serious, bodily injury, as
involuntary
manslaughters.
Id.
§ 215, at 339 (“[o]ne committing a minor assault upon another, not intending to kill, but accidentally doing so, is guilty of involuntary manslaughter”);
id.
at 340-41 (“a killing resulting from an assault by one person upon another is a killing in the commission of an unlawful act [and thus involuntary manslaughter], where, if the blow had not proved mortal, the assailant would have been subject tо prosecution for assault and battery”). The treatment in
Bradford
and Wharton’s treatise of a killing resulting from an assault or battery, such as a bare-fisted blow, not involving intent to kill or inflict serious bodily injury is not surprising; it reflects the traditional and uniform common law rule classifying such killings as involuntary, rather than voluntary, manslaughter.
See
2 W. La-Fave & A. Scott,
supra
note 6, § 7.13, at 296 (“it is almost universally held ... that one is guilty of
involuntary
manslaughter who intentionally inflicts bodily harm upon another person,” thereby causing an unintended and unforeseeable death (emphasis added)); Model Penal Code,
supra,
§ 210.3, comment 8, at 78 & n. 95 and cases cited (“[i]t was an important feature of prevailing law at the time the Model Penal Code was drafted that one who caused the death of another by a simple battery was generally guilty of manslaughter or
of involuntary manslaughter where that was a separate category”
(emphasis added));
see also
2 W. Burdick,
supra,
§ 465a, at 203 (including instances of death caused by a blow by the fist or by a kick as illustrations of involuntary manslaughter). Indeed, in every reported case we have found from a jurisdiction which divides man
*47
slaughter into its voluntary and involuntary forms discussing killings resulting from the delivery of a single or a few blows, not administered with intent to kill or inflict serious bodily injury, such killings are classified as involuntary, rather than voluntary manslaughter.
See, e.g., People v. Morgan,
We must conclude, in conformity with the overwhelming weight of authority on the matter, that voluntary manslaughter involves only those homicides where the perpetrator’s state of mind would constitute malice aforethought and the homicide murder, but for the presence of legally recognized mitigating circumstances. If the perpetrator’s state of mind is not one which would constitute malice, the fact that he or she intends to inflict non-serious injury or otherwise direct force against the victim does not render a killing voluntary manslaughter. Thus, to the extent that a death resulting from conduct accompanied by an intent to cause something less than serious bodily injury rises to the level of an unlawful homicide, it is governed by the involuntary manslaughter doctrines to which we now turn.
E. Involuntary manslaughter
As described in the preceding subsection, voluntary manslaughter is a killing committed with an intent to kill or do serious bodily injury, or with a conscious disregard of an extreme risk of death or serious bodily injury, where the presence of mitigating factors precludes a determination that the killing was malicious. The absence of malice under these circumstances thus reduces the offense to one form of manslaughter. In contrast, where a killing is not committed with a specific intent to kill or do serious bodily injury, or in conscious disregard of an extreme risk of death or serious bodily injury, there is no question that the killing was without malice. 27 However, even such an unintentional or accidental killing is unlawful, and thus constitutes involuntary man *48 slaughter, unless it is justifiable or excusable. Indeed, it is the absence of circumstances of justification or excuse which renders a non-malicious killing “unlawful.” Accordingly, one key to distinguishing those unintentional killings which are unlawful, and hence manslaughter, from those to which no homicide liability attaches 28 is determining the circumstances under which a killing will be legally excused.
Generally, at common law, where a person kills another in doing a “lawful act in a lawful manner,” the homicide is excusable. W. Clark & W. Marshall, supra, § 275, at 371. As this phrase implies, two categories of unintentional killings were not excused and thus were manslaughter: killings in the course of lawful acts carried out in an unlawful, i.e., criminally negligent, 29 fashion, and killings in the course of unlawful, i.e., criminal, acts. 30
1. Criminal-negligence involuntary manslaughter
The law pertaining to the first category, which may be labelled “criminal-negligence” manslaughter, see supra note 29, has undergone considerable transformation, and the cases have steadily narrowed the range of conduct deemed sufficiently culpable to sustain a manslaughter conviction. In the thirteenth century, it appears that even a person who caused death “by misadventure,” or in a completely non-negligent fashion, had no legal defense to a homicide charge. See Perkins, Malice Aforethought, supra note 16, at 539 n. 23, 540. By the mid-eighteenth century, however, if a death-producing act “was done with due caution, or was accompanied only by slight negligence,” the perpetrator lacked the “culpable negligence” required to render the homicide manslaughter. 3 J. Stephen, supra, at 76 (summarizing the views of a treatise published in 1762). Cf. 4 W. BLACKSTONE, supra, at *192 (involuntary manslaughter occurs “where a person does an act, lawful in itself, but in an unlawful manner and without due caution and circumspection”).
Under current law in the District of Columbia, one who unintentionally causes the death of another as the result of non-criminal conduct is guilty of involuntary manslaughter only where that conduct both creates “extreme danger to life or of serious bodily injury,” and amounts to “a gross deviation from a reasonable standard of care.”
Faunteroy v. United States,
2. Misdemeanor involuntary manslaughter
The second category of unexcused unintentional homicides are those occurring in the course of certain unlawful acts. Centuries ago, the “unlawful act” category of involuntary manslaughter included all killings occurring in the course of a criminal act not amounting to a felony, i.e., a misdemeanor. See 3 J. Stephen, supra, at 75 (quoting, and criticizing, the doctrine recorded in a 1762 treatise); see also 4 W. Blackstone, supra, at *192-93. The doctrine became known as the “misdemeanor-manslaughter rule,” something of an analogue to the felony-murder rule. 2 C. TOR-CIA, supra, § 167, at 266; Model Penal Code, supra, § 210.3 comment 1, at 44-45. 33 As time passed, however, the misdemeanor-manslaughter rule “came to be considered too harsh,” and “the courts began to place limitations upon it.” 2 W. LaFave & A. Scott, supra note 6, § 7.13, at 287. Thus, in many jurisdictions, a homicide occurring in the course of a misdemeanor is involuntary manslaughter only if the offense is malum in se, rather than malum prohibitum. 34 2 W. LaFave & A. Scott, supra note 6, § 7.13(c), at 287; R. Perkins & R. Boyce, supra, at 109; 2 C. Torcía, supra, § 167, at 266-67. Where the misdemeanor manslaughter doctrine applies, involuntary manslaughter liability attaches even where the defendant does not act with the degree of recklessness ordinarily required for involuntary manslaughter predicated on criminally negligent behavior. In effect, the defendant’s intentional commissiоn of a misdemeanor supplies the culpability required to impose homicide liability.
*50
In the District of Columbia, the misdemeanor-manslaughter doctrine has developed along substantially similar lines. Although the doctrine is established in the law in this jurisdiction, we have been mindful of the danger that the traditional misdemeanor-manslaughter rule, imposing involuntary manslaughter liability whenever a killing occurs in the commission of a misdemeanor
malum in se,
might cast too wide a net.
35
The risk of an unreasonable application of involuntary manslaughter liability is especially pronounced in view of the massive increase since the early common-law era in the number and forms of misdemeanors. In
Bradford v. United States, supra,
This limitation, however, is incomplete. Although some misdemeanors, at least when viewed in the abstract, prohibit activity which seems inherently dangerous, they may also reach conduct which might not pose such danger. A special difficulty arises in the case of simple assault, as presented here, because that misdemeanor is designed to protect not only against рhysical
injury,
but against all forms of offensive touching,
see Guarro v. United States,
Accordingly, the fact that death results in the commission of what is classified as *51 an inherently dangerous misdemeanor, is alone insufficient to establish guilt of misdemeanor involuntary manslaughter. Rather, the defendant must commit the misdemeanor in a way which is dangerous under the particular circumstances of the case. See 2 W. LaFave & A. Scott, supra note 6, § 7.13(e), at 298 (“the question [in unlawful-act involuntary manslaughter cases] ought to be not whether the crime is generally dangerous, but whether the defendant’s conduct in the particular death-causing situation was under the circumstances dangerous” (emphasis added)). 37 We think a misdemeanor will be dangerous under the circumstances if the manner of its commission entails a reasonably foreseeable 38 risk of appreciable physical injury. 39 If the manner in which an inherently dangerous misdemeanor is committed creates such a foreseeable risk of appreciable physical injury, the defendant should bear the consequences of criminal homicide if the result is not just bodily injury but death itself. 40 A killing resulting from a misdemeanor which does not satisfy the standard just described will be excused. 41
*52 In sum, it can be seen that as a whole, the law of homicide is broadly symmetrical. The four mental states recognized as malicious for purposes of second-degree murder exist in manslaughter, as well. One who acts with the specific intent to kill or to inflict serious bodily injury is guilty of murder. If those two states of mind are accompanied by recognized circumstances of mitigation, however, the crime is voluntary manslaughter. (It is conceivable that voluntary manslaughter liability might arise where one, acting under circumstances of mitigation, consciously disregards an extreme risk of death of serious bodily injury, but such scenarios seem highly improbable.) The other two malicious mental states also have corollaries in the involuntary manslaughter category. One who acts in conscious disregard of an extreme risk of death or serious bodily injury is guilty of murder, but if he or she is only unreasonably unaware of such a risk, the crime is involuntary manslaughter. Finally, one who kills in the course of a felony enumerated in D.C. Code § 22-2401 is guilty of murder, but one who kills in the commission of a misdemeanor, cf. supra note 33, under the circumstances described above is guilty of involuntary manslaughter.
IV. THE INSTANT APPEALS
Guided by the foregoing discussion of the law of manslaughter, we turn now to an assessment of the manslaughter instructions in appellants’ cases. We conclude that the jury instructions given in each case were erroneous.
A. Appellant Comber
Both the voluntary and involuntary manslaughter instructions given in appellant Comber’s case misstated the law as above explicated in significant respects. 42 With regard to voluntary manslaughter, the trial court’s instruction erroneously defined the mental states required for the offense. The trial court instructed the jury that to prove voluntary manslaughter, the government had to prove that the defendant committed an unjustified or unexcused killing, and that the defendant intended to commit the acts which caused death. The trial court then explained that to prove a killing was without justification or excuse, the government had to prove that the defendant did not kill in self-defense. In effect, then, the trial court instructed the jury that as long as he was not acting in self-defense, appellant Comber was guilty of voluntary manslaughter if he intended to commit some act which in fact caused Joseph Pinkney’s death, no matter how unexрectedly. As is plain from our discussion above, however, to be guilty of voluntary manslaughter, a person must intend to kill, intend to inflict serious bodily injury, or act in conscious disregard of an extreme risk of death or serious bodily injury. Although a voluntary manslaughter conviction is proper only where the defendant acts with a state of mind which, but for the presence of mitigating factors, would support a second-degree murder conviction, the instructions in appellant Comber’s case permitted the jury to find him guilty if it found only that he intended to *53 commit some act which resulted in death. 43 The instruction thus allowed the jury to convict Comber of voluntary manslaughter where his mental state and conduct would not constitute that offense. 44
The involuntary manslaughter instruction given in Comber’s case was also erroneous. The instruction described the criminal negligence variety of involuntary manslaughter, not the misdemeanor-manslaughter variety. Had the trial court not modified the standard “redbook” instruction to limit involuntary manslaughter only to deaths resulting from unintentional acts, it would properly have defined the elements of criminal negligence involuntary manslaughter. 45 The instruction properly described the degree to which appellant’s conduct had to deviate from a reasonable person standard and the gravity of the risk required to support an involuntary manslaughter conviction. However, the addition that the jury could find appellant guilty of involuntary manslaughter only if it concluded that appellant Comber’s conduct was not intentional was an incorrect statement of law. Although it is true that an involuntary manslaughter conviction is appropriate only where death is unintentional, the offense is not limited to killings resulting from death-producing conduct which is unintentional. In fact, many intentional acts, provided that they either involve the creation of the requisite risk of death or constitute inherently dangerous misdemeanors committed in such a way that appreciable bodily injury is a foreseeable result, may constitute involuntary manslaughter. The instructions given in appellant Comber’s case thus precluded the jury from finding him guilty of involuntary manslaughter under circumstances where such a verdict might have been appropriate. 46
B. Appellant Hayward
Two types of instructional error similarly occurred at appellant Hayward’s trial. First, the trial court gave the standard voluntary manslaughter instruction, which erroneously defines that offense. 47 Second, the trial court refused to give an involuntary manslaughter instruction upon the defendant’s request.
Unlike the voluntary manslaughter instruction given in appellant Comber’s case, the voluntary manslaughter instruction in appellant Hayward’s case contained *54 no description of the mental state required for the offense but included a definition of justification and excuse. The instruction given to the jury thus contained, in effect, the classic common law definition of the undifferentiated crime of manslaughter. As a voluntary manslaughter instruction, it is thus over-inclusive. The instruction makes voluntary manslaughter of all unexcused homicides, including involuntary manslaughter of both the criminal negligence and misdemeanor varieties. Indeed, given the instruction’s truncated description of the circumstances which would excuse a homicide, 48 the instruction might even permit a voluntary manslaughter conviction in cases where no homicide liability would be appropriate. Furthermore, under the instructions given by the trial court, the jury was authorized to find Hayward guilty of voluntary manslaughter without ever finding that he acted with the mental state required for that offense.
In addition, apparently persuaded by the prosecutor’s argument that involuntary manslaughter is restricted to cases in which death results from an unintentional act, the trial court ruled that an involuntary manslaughter instruction would be inappropriate. However, involuntary manslaughter is by no means limited to cases in which death results from an unintentional act. An intentional act or intentional conduct done with no aim to cause death or serious bodily injury will constitute involuntary manslaughter if it creates an extreme risk of death or serious bodily injury and amounts to non-conscious recklessness. Alternatively, an intentional act which causes death is involuntary manslaughter if it is a misdemeanor dangerous in and of itself which is committed in a manner such that appreciable bodily injury to the victim was a reasonably foreseeable result. ■ The evidence in appellant Hayward’s case was sufficient to support an involuntary manslaughter jury instruction under either theory.
Day v. United States,
C. Disposition
At bottom, the key element of discussion in this case is not whether appellants were improperly convicted of manslaughter, but whether they were convicted of the proper type of manslaughter.
See Williams v. United States,
Reversed and remanded.
. The italicized portions of the instruction reflect deviations from the standard "redbook" voluntary manslaughter instruction. See Criminal Jury Instructions for the District of Columbia, No. 4.25 (3d ed. 1978). The standard instruction does not include the third element that the defendant intend to commit the acts which caused death. Additionally, the trial court modified the standard instruction’s explanation’s explanation of justifiable and excusable homicide. The standard instruction provides:
*34 Justifiable homicide is the necessary killing of another in the performance of a legal duty, or where the person who kills, not being himself at fault, had a legal right to kill.
Excusable homicide occurs where the person who kills, although himself at fault, had the legal right so to kill, or where the killing was the accidental result of a lawful act done in a lawful manner.
Id. In appellant Comber’s case, the trial court’s instruction limited the definition of justifiable or excusable homicide to killings in self-defense.
Notes
.After each of these appeals was argued before different panels, we sua sponte determined to hear the cases en banc. Wе requested the parties to submit supplemental briefs addressing:
the definition, scope, and limits of the common-law crime of manslaughter, as well as the propriety of current standard jury instructions on manslaughter. Included among the court’s concerns are:
1. The distinction between voluntary and involuntary manslaughter
2. The significance of the distinction between voluntary and involuntary manslaughter, in light of the fact that both are identically punished pursuant to a single statutory provision. D.C.Code § 22-2405 (1989).
3. The distinction between manslaughter— both voluntary and involuntary — and second degree murder.
4. The distinction between involuntary manslaughter and homicides for which no criminal liability attaches.
. The italicized portion reflects an emendation to the standard "redbook" involuntary manslaughter instruction. See Criminal Jury Instructions for the District of Columbia, supra note 2, No. 4.26. Additionally, as in its voluntary manslaughter instruction, the trial court's involuntary manslaughter instruction informed the jury that to prove that the killing was committed without legal justification or excuse, the government had only to show "that the defendant did not act in self-defense.”
The trial court also instructed the jury that it should consider the involuntary manslaughter offense only if it first concluded that the defendant was not guilty of voluntary manslaughter. See infra note 46.
. The trial court's voluntary manslaughter instruction is identical in all substantive respects to the standard "redbook” instruction for that offense. See Criminal Jury Instructions for the District of Columbia, supra note 2, No. 4.25.
. As we recently explained, under D.C.Code § 49-301 (1987), this court is "bound by Maryland common law in effect as of 1801 (incorporating English common law and statutes in effect as of 1776) unless expressly repealed or modified by statute.”
Williams, supra,
by incorporating the common law of Maryland, Congress did not intend to freeze the common law as it existed in 1801. Rather, Congress meant to incorporate the "dynamic” common law, not merely "its then-current pronouncements on specific problems." As a consequence, [we have] concluded that D.C. Code § 49-301 “is not a bar to the exercise of our inherent рower to alter or amend the common law.”

see also Bradford, supra,
. The Model Penal Code includes a provision, less serious than manslaughter, imposing homicide liability for killings "committed negligently.” Model Penal Code, supra, § 210.4. Many states have adopted similar “negligent homicide statutes.” See 2 W. LaFave & A. Scott, Substantive Criminal Law §§ 7.12(a), 7.12(e), at 280, 287 (1986); R. Perkins & R. Boyce, supra, at 118. Accordingly, in these jurisdictions it is not true that a homicide which is neither murder nor manslaughter is necessarily justified or excused. Most of the jurisdictions which have adopted such negligent homicide provisions, however, have restricted the involuntary manslaughter liability to cases where the actor is conscious of the risk of death or serious bodily injury created by his or her conduct. 2 W. LaFave & A. Scott, supra, § 7.12(a), at 278. (As discussed below, in the District of Columbia, the actor need not be conscious of a criminally culpable risk for involuntary manslaughter liability to attach.) What constitutes negligent homicide in jurisdictions which have adopted such statutes most likely would have constituted involuntary manslaughter at common law. R. Perkins & R. Boyce, supra, at 117.
Although the District of Columbia Code contains no general negligent homicide statute, it does include a special "negligent homicide" provision pertaining to the operation of vehicles. This statute makes it a felony to “cause the death of another” by the "operation of any vehicle in a careless, reckless, or negligent manner.” D.C.Code § 40-713 (1990). The offense is "deemed to be included within every crime of manslaughter charged to have been committed in the operation of any vehicle.” D.C.Code § 40-714 (1990).
. According to Blackstone, involuntary manslaughter resulted where оne killed unintentionally in the course of a non-felonious unlawful act, id. at *192-93, or "where a person does an act, lawful in itself, but in an unlawful manner, and without due caution and circumspection." Id. at *192. Voluntary manslaughter occurred “if upon a sudden quarrel two persons fight, and one of them kills the other.” Id. at *191.
. As indicated above, the legislature had drawn no statutory distinction between voluntary and involuntary manslaughter in the District of Columbia. See D.C.Code § 22-2405 (1989) (imposing a maximum punishment of 15 years imprisonment and/or a 51,000 fine for the undifferentiated crime of manslaughter). Nevertheless, even under this statutory structure, where the evidence in a case might sustain a conviction for either voluntary or involuntary manslaughter, appropriate jury instructions defining the two offenses will permit the trial court to consider the offense of which the jury has convicted the defendant for sentencing purposes. Additionally, the distinction between the form of manslaughter of which a defendant has been convicted may have significant collateral consequences.
. Although first and second degree murders are defined by statute,
see
D.C.Code §§ 22-2401, -2403 (1989), those statutes embody the common law definition of murder.
See Byrd v. United States,
. LaFave and Scott describe how an intent to inflict serious bodily injury came to constitute malice:
[T]he English judges came to hold that one who intended to do serious bodily injury short of death, but who actually succeeded in killing, was guilty of murder in spite of his lack of an intent to kill, in the absence of circumstances which mitigated the offense to voluntary manslaughter or which justified or excused it. This type of common-law murder became a part of the law of murder in America.
2 W. LaFave & A. Scorr, supra note 6, § 7.3, at 197 (footnotes omitted). See also 2 W. Burdick, supra, § 450, at 168 (“intent ... to do any serious bodily harm” constitutes express malice); Model Penal Code, supra, § 210.2 comment 1, at 14-15 (“[a] second species of murder involved intent to cause grievous bodily harm”); R. Perkins & R. Boyce, supra, at 59 (”[a]n intent to inflict great bodily injury is sufficient for malice aforethought if there is no justification, excuse, or mitigation”).
Our cases do not provide much guidance as to what constitutes serious bodily harm in the second-degree murder context. Cf. Cal.Penal Code § 243(f)(5) (West 1988) (for statute prescribing punishment for battery, defining "serious bodily injury” as "a serious impairment of physical condition, including, but not limited to, the following: loss of consciousness; concussion; bone fracture; protracted loss or impairment of function of any bodily member or organ; a wound requiring extensive suturing; and serious disfigurement”).
. See also 2 W. LaFave & A. Scott, supra note 6, § 7.4, at 199-200 ("[ejxtremely negligent conduct, which creates ... not only an unjustifiable but also a very high degree of risk of death or serious bodily injury to ... others — though unaccompanied by any intent to kill or do serious bodily injury — and which actually causes the death of another, may constitute murder”); Model Penal Code, supra, § 210.2 comment 1, at 15 (malice can arise from "extreme recklessness regarding homicidal risk”).
. The fact that a reasonable person would have been aware of the risk will not sustain a finding of malice, though it may sustain a conviction for manslaughter.
See Powell v. United States,
. Examples of conduct rising to the level of depraved heart malice include:
firing a bullet into a room occupied, as the defendant knows, by several people; starting a fire at the front door of an occupied dwelling; shooting into ... a moving automobile, necessarily occupied by human beings ...; playing a game of "Russian roulette” with another person....; selling "pure” (i.e., undiluted) heroin.
2 W. LaFave
&
A. Scott,
supra
note 6, § 7.4, at 202-03 (footnotes omitted). An example of "depraved heart” murder in this jurisdiction appears in
Powell v. United States, supra,
. At least where purposeful killings are concerned, the terms of D.C.Code § 22-2401 apply to one who kills in the course of "any offense punishable by imprisonment in the penitentiary.” In 1901, the time of the original enactment of the District of Columbia murder statute, governing law provided that one who committed an offense carrying a potential punishment of im
*40
prisonment for no more than one year was to be imprisoned either in the “workhouse” or the "jail.” A sentence to a period longer than one year was to be served in the "penitentiary."
See
Act of March 3, 1901, ch. 854, § 934, 31 Stat. 1189, 1341;
see also United States v. Evans,
. What remains unclear in the District of Columbia is the status of one who commits a non-purposeful killing in the course of a felony not specified in D.C.Code § 22-2401.
See Towles v. United States,
Prior to 1940, the felony-murder doctrine applied in the District of Columbia to felonies other than those recognized at common law.
See, e.g., Lee v. United States,
. At early common law, an intentional killing was "justifiable,” and thus no crime, if it was *41 "commanded or authorized by law.” R. Perkins & R. Boyce, supra, at 1124. Examples of justifiable homicides included "the killing of an enemy on the field of battle as an act of war within the rules of war,” "the execution of a sentence of death pronounced by a competent tribunal,” id., or "the 'slaying of an outlaw ... who resists capture.'" Perkins, A Re-Examination of Malice Aforethought, 43 Yale LJ. 537, 539-40 (1934) (citation omitted) [hereinafter "Malice Afore thought"]. Excusable homicide was a more amorphous category, encompassing killings which, for various reasons, were deemed not to warrant criminal punishment. Examples included killings in self-defense, accidental and non-negligent killings, and "killings by a madman.” R. Perkins & R. Boyce, supra, at 1124. Although "excuse" was originally only a basis for royal pardon, and not an acquittal, evidence of circumstances of excuse “disproved the charge itself" by the sixteenth century. Perkins, Malice Aforethought, supra, at 540. Perkins argues that to the extent "the distinction between justifiable and excusable homicide is to be retained in modern law,” one who kills in self-defense "should be said to have committed justifiable homicide ... because what is authorized by law is in every proper sense, justified.” Id. at 541 n. 39.
. However, the government’s obligation to disprove justification, excuse, or mitigation arises only when there is some evidence of one or more of these circumstances in the case.
Logan, supra,
. In light of the evolution of the crime of murder, commentators have criticized the use of the phrase "malice aforethought” to describe the mental state required for the offense.
See
W. Burdick,
supra,
§ 448, at 161 ("[t]he literal and ordinary meanings of the words [malice aforethought] no longer help, but rather mislead”); R. Perkins & R. Boyce,
supra,
at 57 ("[t]he phrase 'malice aforethought' is peculiarly confusing to the layman because each word has a different significance in legal usage than in ordinary conversation"). Moreover, the standard "redbook” instruction on malice, Criminal Jury Instructions for the District of Columbia,
supra
note 2, No. 4.23 ("Murder in the Second Degree”);
id.
No. 4.21 ("Murder in the First Degree —Premeditated”), particularly its use of the terms "express” and “implied" malice, has been characterized as imprecise and potentially confusing.
Powell, supra
note 12,
. Neither the presence of mitigating circumstances, nor malice, to the extent that phrase encompasses the absence of all elements of justification, excuse, or mitigation, is an element of voluntary manslaughter which the government must prove beyond a reasonable doubt.
See United States v. Alexander,
The presence of mitigating circumstances, though a defense to a second-degree murder charge, is not a defense to a charge of voluntary manslaughter.
. Perkins and Boyce make clear elsewhere that they use the phrase "person-endangering-state-of-mind” to describe either intent to kill, intent to inflict great bodily injury, intent to do an act in wanton and wilful disregard of an unreasonable human risk, or an intent to perpetrate a dangerous felony. Id. at 73. In short, Perkins and Boyce use the phrase as a shorthand way of describing the states of mind which, in the absence of justification, excuse, or mitigation, would constitute malice aforethought.
. A number of the formulations quoted suggest that voluntary manslaughter is limitеd to cases in which the defendant acts with the specific intent to kill the victim. Strictly speaking, this is too narrow a definition. Although one who intends to kill certainly acts with a state of mind that, absent mitigating factors, would constitute malice, it is not the only malicious state of mind. As explained above, one who specifically intends to inflict serious bodily injury or who acts in conscious disregard of an extreme risk of death or serious bodily injury also acts with malice, absent circumstances of justification, excuse, or mitigation. Thus, notwithstanding the absence of a specific intent to kill, one who acts with specific intent to inflict serious bodily injury or in conscious disregard of an extreme risk of death or serious bodily injury may also be guilty of voluntary manslaughter, provided the killing occurs under recognized circumstances of mitigation and is therefore not murder. See 2 W. LaFave & A. Scott, supra note 6, § 7.10, at 252-53 (in addition to "intent-to-kill" homicides committed under mitigating circumstances, "killings which constitute voluntary manslaughter ... might be of the intent-to-do-serious-bodily-injury, or of the depraved heart, types”).
The statement in the
Bradford
opinion that "the requisite intent [for voluntary manslaughter is] the general intent to do the act which caused death rather than a specific intent to cause death,”
Bradford, supra,
. Several statements in Bradford might be construed to support the view that voluntary manslaughter occurs whenever death results from the application of any force against the victim. At one point, the opinion indicates that one acts with the requisite mental state for manslaughter where, "even though the accused did not intend to kill, he did intend to use such force against the decedent as would endanger him.” Id. at 214. See abo id. at 216 n. 24 (“voluntary manslaughter involves an intent to endanger or apply force”). But see supra note 21 (suggesting that the concept of intent to endanger encompasses intent to inflict serious bodily injury and conscious disregard of an extreme risk of death or serious bodily injury). Elsewhere, in a footnote summarizing the discussion of voluntary and involuntary manslaughter in a 1907 edition of Wharton’s treatise on homicide, the Bradford opinion states: “Voluntary manslaughter at common law includes all felonious homicides which result directly from any unlawful force aimed at or applied to the party slain.... ” Id. at 214 n. 14. But see infra p. 45-46 (discussing why Wharton's treatise does not support the view that death resulting from an assault committed without a malicious mental state is voluntary manslaughter). The opinion also suggests at one point that the requisite intent for voluntary manslaughter is “the general intent to do the act which caused death.” Id. at 214. But see supra note 21 (clarifying Bradford and indicating that voluntary manslaughter is not a general intent crime).
Other language in Bradford seemingly supports a corollary of the position advanced by the government, namely, that a death resulting from the application of any force against the victim cannot constitute involuntary manslaughter. See id. at 215 (“Involuntary manslaughter is an unlawful killing which is unintentionally committed. By unintentionally it is meant that there is not intent to kill or to do bodily injury”). Similarly, in describing the criminal negligence variety of involuntary manslaughter, see infra, the court stated, “[tjhe state of mind in involuntary manslaughter is characterized ... by a lack of intent to cause death or injury." Additionally, in summarizing language from Wharton's 1907 homicide treatise, the court noted that "involuntary manslaughter at common law includes homicides which were the accidental result of some unlawful act less than a felony, not aimed at or directed against the person slain.” Id. at 214 n. 14.
As we explain in the accompanying text, however, we believe that the court in Bradford adopted a definition of voluntary manslaughter as a killing committed with a state of mind which would constitute malice but for the presence of mitigating circumstances. To the extent there is any ambiguity in Bradford, it is to be resolved in conformity with our decision today.
. It must be remembered that in
Bradford,
the court was not faced with any specific fact situation, but rather was resolving the issue whether voluntary and involuntary manslaughter must be charged as separate counts in an indictment.
Bradford, supra,
. See also id. at 214 (voluntary manslaughter is a killing “‘committed with a design to kill, under the influence of a sudden and violent passion caused by great provocation’ ” (citation omitted, emphasis added)); id. (“the requisite intent in voluntary manslaughter approximates express malice").
. The government also cites
Ruffin v. United States,
. The government also relies on
Norton v. State,
. We may ignore for purposes of this assertion the felony-murder rule.
. At common law, a killing which was not "unlawful” so as to constitute manslaughter resulted in no criminal liability. But see supra note 6.
. As used here, "criminally negligent” is a generic term used to describe the appropriate degree of negligence required to render a killing involuntary manslaughter. As discussed below, the law has evolved to demand increasingly heightened levels of negligence for an involuntary manslaughter conviction. Additionally, jurisdictions today differ on the degree of negligence required to render an unintentional or accidental killing involuntary manslaughter.
. This dichotomy dеrives from the common law at the time of Blackstone, who indicated that involuntary manslaughter resulted where one killed unintentionally in the course of a non-felonious unlawful act, 4 W. Blackstone,
supra,
at *192-93, or “where a person does an act, lawful in itself, but in an unlawful manner, and without due caution and circumspection.”
Id.
at *192. In
Bradford, supra,
.By describing the standard of risk creation required to render a killing involuntary manslaughter, the standard "redbook” jury instruction implicitly incorporates the absence of excuse element of involuntary manslaughter, except in cases of self-defense. See Criminal Jury Instructions for the District of Columbia, supra note 2, No. 4.26. Accordingly, absent evidence of justification or rare forms of excuse which seldom arise, the trial court need only charge the jury separately as to the requirement that the killing be without justification or excuse when there is evidence of self-defense. In such cases, the trial court can explain that the ab *49 sence of justification or excuse means that the government must prove beyond a reasonable doubt that the killing was not in self-defense and then define that concept for the jury.
.In this regard, the law in the District of Columbia differs from the prevailing approach to “criminal-negligence” manslaughter. Most jurisdictions appear to permit the imposition of involuntary manslaughter liability on death-producing conduct involving something less than an "extreme” risk of death or serious bodily; a "high degree of risk of death or serious bodily injury” will suffice. 2 W. LaFave & A. Scorr,
supra
note 6, § 7.12, at 278.
See, e.g., Commonwealth v. Catalina,
. Although we use the phrase "misdemeanor-manslaughter rule” in this opinion, we recognize that the term may be something of a misnomer, in that felonies which might not otherwise suffice to give rise to felony murder liability, see supra note 15, might serve as a basis for “unlawful act” involuntary manslaughter liability. 2 W. LaFave & A. Scott, supra note 6, § 7.13(a), at 288. See also R. Perkins & R. Boyce, supra, at 112 n. 50.
. Malum in se is defined as "[a] wrong in itself.... An act is said to be malum in se when it is inherently and essentially evil, that is, immoral in its nature and injurious in its consequences, without any regard to the fact of its being noticed or punished by the law of the state.” Black’s Law Dictionary 865 (5th ed. 1979). Malum prohibitum is defined as "[a] wrong prohibited ...; an act which is not inherently immoral, but becomes so because its commission is expressly forbidden by positive law_” Id.
. Despite its long-standing roots, the misdemeanor-manslaughter rule has been criticized in recent years. This criticism has been directed primarily at the absence of a foreseeability of harm requirement in misdemeanor-manslaughter.
See, e.g.,
R. Perkins & R. Boyce,
supra,
at 114; Model Penal Code,
supra,
§ 210.3 comment 7, at 77. ”[A]bout two-thirds of the modern [state] codes do not contain a manslaughter crime grounded in the defendant’s death-causing unlawful act.” 2 W. LaFave & A. Scorr,
supra
note 6, § 7.13, at 287. In other jurisdictions, courts have abolished or refused to apply the misdemeanor-manslaughter rule.
See, e.g., Catalina, supra
note 32, 407 Mass, at 787,
. At trial, Walker was convicted "on a count charging 'involuntary manslaughter in perpetrating and attempting to perpetrate the crime of carrying a pistol without a license.’"
Walker v. United States,
. Although the determination whether a misdemeanor is inherently dangerous is a legal question for the court,
see Walker I, supra,
. By foreseeable, we mean not that appreciable bodily injury must be the normal consequence of the conduct, but a possible consequence.
See, e.g., McKinnon v. United States,
. The same analysis applies to other misdemeanors. For example, although the court in
Walker I
concluded that carrying a weapon without a license in violation of D.C.Code § 22-3204 is dangerous in and of itself, that might be true only if the gun is loaded or displayed in a menacing fashion. For example, one is guilty of carrying a pistol without a license evеn if he or she carries an unloaded, but unlicensed, pistol. However, if he or she drops the pistol down a stairwell in a non-reckless fashion, and it hits someone on the head, causing death, it could not fairly be said that the manner in which the violation of the statute occurred involved a foreseeable risk of physical injury. On the other hand, if one carries a loaded pistol and drops it down a stairwell, and the gun discharges, causing death, the manner in which the violation of the statute occurred, that is, carrying the loaded pistol, could involve such a foreseeable risk.
See Walker II, supra
note 36,
. We note that some courts and commentators either require or suggest that the actor's conduct must create a reasonably foreseeable risk of death or serious bodily injury, not merely appreciable bodily injury, before misdemeanor-manslaughter liability should attach.
See, e.g., Catalina, supra
note 32, 407 Mass, at 787,
. Just as with voluntary manslaughter, see supra note 19, if the jury is properly instructed on *52 the foreseeability of appreciable bodily injury standard, the absence of justification or excuse element of involuntary manslaughter ordinarily will already be incorporated into the definition of the offense. Accordingly, absent circumstances of justification or rare forms of excuse which seldom arise, the trial court need only charge the jury separately as to the requirement that the killing be without justification or excuse where there is evidence of self-defense.
. The government argues that appellant Comber failed to object to the specific wording of the instructions, and that any error should thus be viewed under the plain error standard. We disagree. The record demonstrates that when the trial court proposed giving a voluntary manslaughter instruction, counsel for Comber immediately objected. During an extended colloquy conducted over the course of two days, the parties discussed at length whether a killing resulting from the intentional application of force against an individual, not motivated by an intent to kill or inflict serious bodily injury, constitutes voluntary or involuntary manslaughter. Appellant Comber's position was clear that a killing resulting from a simple assault constitutes involuntаry manslaughter of the misdemeanor-manslaughter variety, not voluntary manslaughter.
. As noted above, voluntary manslaughter is not a general intent crime in the sense suggested by the instructions here. See supra note 21.
. Indeed, since nothing was said about justification or excuse other than self-defense, the instruction would have permitted a voluntary manslaughter conviction on the basis of conduct which does not amount to criminal homicide at all. Under the instructions given here, a person who, acting in a completely non-negligent fashion, intentionally committed a lawful act which freakishly caused the death of another would be guilty of voluntary manslaughter.
. Under the circumstances of the case, the trial court’s modified explanation of the circumstances constituting justification or excuse was proper. See supra note 41.
. Appellant Comber also correctly argues that the trial court erred in instructing the jury that involuntary manslaughter is a lesser-included offense of voluntary manslaughter, and that it could consider the involuntary manslaughter charge only if it first found appellant not guilty of voluntary manslaughter.
See supra
note 3. This error alone could require reversal, ■ something we need not Here decide. In
Bradford, supra,
.The government contends that appellаnt Hayward never objected to the wording of the voluntary manslaughter instruction, and that we must review that contention under the plain error standard. It is uncontested, however, that Hayward vigorously requested an involuntary manslaughter instruction, a request denied by the trial court.
. The instructions provided, in pertinent part: "Excusable homicide occurs where the person who kills although himself at fault had the legal right so to kill or where the killing was the accidental result of a lawful act done in a lawful manner.” As the discussion above demonstrates, however, a homicide resulting from a lawful act is excused so long as it does not involve conduct which creates "extreme danger to life or of serious bodily injury” and does not amount to “a gross deviation from a reasonable standard of care."
Faunteroy, supra,
. Because of our disposition of the case on grounds of instructional error, we need not decide whether appellant’s prosecutorial misconduct allegations, standing alone, would warrant reversal.
. The government also might have proceeded on a recklessness theory, on the view that appellants created an extreme risk of death or serious bodily injury by forcefully striking the decedents in the face.
. We do not rule on the applicability of this decision either to convictions already final or to cases currently pending in which the litigants have not raised an appropriate challenge to the manslaughter instructions.
