To be entitled to an instruction on involuntary intoxication, the defendant must come forward with credible and sufficient evidence of intoxication to the extent that the defendant was unable to distinguish right from wrong. State v. Gardner, 230 Wis. 2d 32
, 601 N.W.2d 670
(Ct. App. 1999), 98-2655
Alcoholism as a defense. 53 MLR 445.
Due Process and the Voluntary Intoxication Defense. Larson. Wis. Law. Feb. 2019.
An honest error, whether of fact or of law other than criminal law, is a defense if it negatives the existence of a state of mind essential to the crime.
A mistake as to the age of a minor or as to the existence or constitutionality of the section under which the actor is prosecuted or the scope or meaning of the terms used in that section is not a defense.
The prosecution of an individual who relied on a governmental official's statutorily required legal opinion would impose an unconscionable rigidity in the law. State v. Davis, 63 Wis. 2d 75
, 216 N.W.2d 31
Mistake is not a defense to criminal negligence. A defendant's subjective state of mind is not relevant to determining criminal negligence. State v. Lindvig, 205 Wis. 2d 100
, 555 N.W.2d 197
(Ct. App. 1996), 96-0235
Adequate provocation. 939.44(1)(a)
“Adequate" means sufficient to cause complete lack of self-control in an ordinarily constituted person.
“Provocation" means something which the defendant reasonably believes the intended victim has done which causes the defendant to lack self-control completely at the time of causing death.
Adequate provocation is an affirmative defense only to first-degree intentional homicide and mitigates that offense to 2nd-degree intentional homicide.
History: 1987 a. 399
Judicial Council Note, 1988:
Sub. (1) codifies Wisconsin decisions defining “heat of passion" under prior s. 940.05. Ryan v. State, 115 Wis. 488 (1902); Johnson v. State, 129 Wis. 146 (1906); Carlone v. State, 150 Wis. 38 (1912); Zenou v. State, 4 Wis. 2d 655
(1958); State v. Bond, 41 Wis. 2d 219
(1969); State v. Williford, 103 Wis. 2d 98
Traditionally, provocation had 2 essential requirements. State v. Williford, supra., at 113. The first reflected in sub. (1) (b), is subjective. The defendant must have acted in response to provocation. This necessitates an assessment of the particular defendant's state of mind at the time of the killing. The 2nd requirement, reflected in sub. (1) (a), is objective. Only provocation sufficient to cause a reasonable person to lose self-control completely is legally adequate to mitigate the severity of the offense.
Sub. (2) clarifies that adequate provocation is an affirmative defense to first-degree intentional homicide. Although adequate provocation does not negate the intent to kill such that the burden of persuasion rests on the state by constitutional principles (Mullaney v. Wilbur, 421 U.S. 684
, (1975), Wisconsin has chosen to place the burden of disproving this defensive matter on the prosecution beyond a reasonable doubt. State v. Lee, 108 Wis. 2d 1
(1982). Since adequate provocation is not an affirmative defense to 2nd-degree intentional homicide, its effect is to mitigate the severity of an intentional homicide from first to 2nd degree. [Bill 191-S]
Adequate provocation includes both subjective and objective components. As to the subjective component, the defendant must actually believe the provocation occurred, and the lack of self-control must be caused by the provocation. As to the objective component, the provocation must be such that would cause an ordinary, reasonable person to lack self-control completely, and the defendant's belief that the provocative acts occurred must be reasonable. State v. Schmidt, 2012 WI App 113
, 344 Wis. 2d 336
, 824 N.W.2d 839
To place provocation in issue, there need be only “some" evidence supporting the defense. The defendant's proffered evidence of provocation must be examined as a whole to determine whether the “some evidence" threshold is satisfied. It is an all-or-nothing determination as to whether the jury hears any evidence of the affirmative defense. The adequate provocation inquiry is fact-driven. If the victim's prior acts could contribute to a reasonable person's loss of self-control at the time of the crime, the acts are relevant to the objective component of the defense. State v. Schmidt, 2012 WI App 113
, 344 Wis. 2d 336
, 824 N.W.2d 839
The fact that the actor's conduct is privileged, although otherwise criminal, is a defense to prosecution for any crime based on that conduct. The defense of privilege can be claimed under any of the following circumstances:
When the actor's conduct occurs under circumstances of coercion or necessity so as to be privileged under s. 939.46
When the actor's conduct is in defense of persons or property under any of the circumstances described in s. 939.48
When the actor's conduct is in good faith and is an apparently authorized and reasonable fulfillment of any duties of a public office; or
When the actor's conduct is a reasonable accomplishment of a lawful arrest; or
“Person responsible for the child's welfare" includes the child's parent, stepparent or guardian; an employee of a public or private residential home, institution or agency in which the child resides or is confined or that provides services to the child; or any other person legally responsible for the child's welfare in a residential setting.
When the actor's conduct is reasonable discipline of a child by a person responsible for the child's welfare. Reasonable discipline may involve only such force as a reasonable person believes is necessary. It is never reasonable discipline to use force which is intended to cause great bodily harm or death or creates an unreasonable risk of great bodily harm or death.
When for any other reason the actor's conduct is privileged by the statutory or common law of this state.
The privilege under sub. (3) for public officials acting with apparent authority did not apply to a volunteer fire fighter driving while under the influence of an intoxicant. State v. Schoenheide, 104 Wis. 2d 114
, 310 N.W.2d 650
(Ct. App. 1981).
A foster parent is a “person legally responsible for the child's welfare" under sub. (5). State v. West, 183 Wis. 2d 46
, 515 N.W.2d 484
(Ct. App. 1994).
A mother's live-in boyfriend did not have parental immunity under sub. (5). The boyfriend did not have legal responsibility for the mother's children, and the term “parent" will not be interpreted to include persons in loco parentis
. State v. Dodd, 185 Wis. 2d 560
, 518 N.W.2d 300
(Ct. App. 1994)
A convicted felon's possession of a firearm is privileged under sub. (6) in limited enumerated circumstances. State v. Coleman, 206 Wis. 2d 199
, 556 N.W.2d 701
There is no statutory or common law privilege for the crime of carrying a concealed weapon under s. 941.23. State v. Dundon, 226 Wis. 2d 654
, 594 N.W.2d 780
Sub. (6) incorporates excusable homicide by accident or misfortune. Accident is a defense that negatives intent. If a person kills another by accident, the killing could not have been intentional. Accident must be disproved beyond a reasonable doubt when a defendant raises it as a defense. When the state proves intent to kill beyond a reasonable doubt, it necessarily disproves accident. State v. Watkins, 2002 WI 101
, 255 Wis. 2d 265
, 647 N.W.2d 244
A defendant may demonstrate that he or she was acting lawfully, a necessary element of an accident defense, by showing that he or she was acting in lawful self-defense. Although intentionally pointing a firearm at another constitutes a violation of s. 941.20, under s. 939.48 (1) a person is privileged to point a gun at another person in self-defense if the person reasonably believes that the threat of force is necessary to prevent or terminate what he or she reasonably believes to be an unlawful interference. State v. Watkins, 2002 WI 101
, 255 Wis. 2d 265
, 647 N.W.2d 244
To overcome the privilege of parental discipline in sub. (5), the state must prove beyond a reasonable doubt that only one of the following is not met: 1) the use of force must be reasonably necessary; 2) the amount and nature of the force used must be reasonable; and 3) the force used must not be known to cause, or create a substantial risk of, great bodily harm or death. Whether a reasonable person would have believed the amount of force used was necessary and not excessive must be determined from the standpoint of the defendant at the time of the defendant's acts. The standard is what a person of ordinary intelligence and prudence would have believed in the defendant's position under the circumstances that existed at the time of the alleged offense. State v. Kimberly B., 2005 WI App 115
, 283 Wis. 2d 731
, 699 N.W.2d 641
Testimony supporting the defendant father's assertion that he was beaten with a belt as a child was not relevant to whether the amount of force he used in spanking his daughter was objectively reasonable. A parent may not abuse his or her child and claim that conduct is reasonable based on his or her history of being similarly abused. State v. Williams, 2006 WI App 212
, 296 Wis. 2d 834
, 723 N.W.2d 719
A threat by a person other than the actor's coconspirator which causes the actor reasonably to believe that his or her act is the only means of preventing imminent death or great bodily harm to the actor or another and which causes him or her so to act is a defense to a prosecution for any crime based on that act, except that if the prosecution is for first-degree intentional homicide, the degree of the crime is reduced to 2nd-degree intentional homicide.
It is no defense to a prosecution of a married person that the alleged crime was committed by command of the spouse nor is there any presumption of coercion when a crime is committed by a married person in the presence of the spouse.
A petitioner under s. 813.12
, or an individual whose parent, stepparent, or legal guardian filed a petition under s. 813.122
on behalf of the individual as a child victim, as defined in s. 813.122 (1) (c)
, has an affirmative defense for an offense under s. 175.35 (2e)
that is punishable under s. 175.35 (3) (b) 2.
, or for an offense under s. 941.2905
, if the person prohibited from possessing a firearm was the respondent in the action under s. 813.12
Judicial Council Note, 1988: Sub. (1) is amended by conforming references to the statute titles created by this bill. Since coercion mitigates first-degree intentional homicide to 2nd degree, it is obviously not a defense to prosecution for the latter crime. [Bill 191-S]
The state must disprove an asserted coercion defense beyond a reasonable doubt. Moes v. State, 91 Wis. 2d 756
, 284 N.W.2d 66
The coercion defense is limited to the most severe form of inducement. It requires finding that the actor believed he or she was threatened with immediate death or great bodily harm with no possible escape other than the commission of a criminal act. A defendant seeking a coercion defense instruction must meet the initial burden of producing evidence to support giving an instruction. That the defendant reasonably believed that a companion would attempt to harm him or her if he if he or she did not comply with the companion's orders only suggests that the safest course was to comply with companion's orders, not that it was the only course. State v. Keeran, 2004 WI App 4
, 268 Wis. 2d 761
, 674 N.W.2d 570
Pressure of natural physical forces which causes the actor reasonably to believe that his or her act is the only means of preventing imminent public disaster, or imminent death or great bodily harm to the actor or another and which causes him or her so to act, is a defense to a prosecution for any crime based on that act, except that if the prosecution is for first-degree intentional homicide, the degree of the crime is reduced to 2nd-degree intentional homicide.
History: 1987 a. 399
Judicial Council Note, 1988: This section is amended by conforming references to the statute titles created by this bill. Since necessity mitigates first-degree intentional homicide to 2nd degree, it is obviously not a defense to prosecution for the latter crime. [Bill 191-S]
The defense of necessity was unavailable to a demonstrator who sought to stop a shipment of nuclear fuel on the grounds of safety. State v. Olsen, 99 Wis. 2d 572
, 299 N.W.2d 632
(Ct. App. 1980).
Heroin addiction is not a “natural physical force" as used in this section. An addict, caught injecting heroin in jail, who was not provided methadone as had been promised, was not entitled to assert necessity against a charge of possession of heroin because his addiction ultimately resulted from his conscious decision to start using illegal drugs. State v. Anthuber, 201 Wis. 2d 512
, 549 N.W.2d 477
(Ct. App. 1996), 95-1365
Self-defense and defense of others. 939.48(1)(1)
A person is privileged to threaten or intentionally use force against another for the purpose of preventing or terminating what the person reasonably believes to be an unlawful interference with his or her person by such other person. The actor may intentionally use only such force or threat thereof as the actor reasonably believes is necessary to prevent or terminate the interference. The actor may not intentionally use force which is intended or likely to cause death or great bodily harm unless the actor reasonably believes that such force is necessary to prevent imminent death or great bodily harm to himself or herself.
“Place of business" means a business that the actor owns or operates.
If an actor intentionally used force that was intended or likely to cause death or great bodily harm, the court may not consider whether the actor had an opportunity to flee or retreat before he or she used force and shall presume that the actor reasonably believed that the force was necessary to prevent imminent death or great bodily harm to himself or herself if the actor makes such a claim under sub. (1)
and either of the following applies:
The person against whom the force was used was in the process of unlawfully and forcibly entering the actor's dwelling, motor vehicle, or place of business, the actor was present in the dwelling, motor vehicle, or place of business, and the actor knew or reasonably believed that an unlawful and forcible entry was occurring.
The person against whom the force was used was in the actor's dwelling, motor vehicle, or place of business after unlawfully and forcibly entering it, the actor was present in the dwelling, motor vehicle, or place of business, and the actor knew or reasonably believed that the person had unlawfully and forcibly entered the dwelling, motor vehicle, or place of business.
The presumption described in par. (ar)
does not apply if any of the following applies:
The actor was engaged in a criminal activity or was using his or her dwelling, motor vehicle, or place of business to further a criminal activity at the time.
The person against whom the force was used was a public safety worker, as defined in s. 941.375 (1) (b)
, who entered or attempted to enter the actor's dwelling, motor vehicle, or place of business in the performance of his or her official duties. This subdivision applies only if at least one of the following applies:
The public safety worker identified himself or herself to the actor before the force described in par. (ar)
was used by the actor.
The actor knew or reasonably should have known that the person entering or attempting to enter his or her dwelling, motor vehicle, or place of business was a public safety worker.
Provocation affects the privilege of self-defense as follows:
A person who engages in unlawful conduct of a type likely to provoke others to attack him or her and thereby does provoke an attack is not entitled to claim the privilege of self-defense against such attack, except when the attack which ensues is of a type causing the person engaging in the unlawful conduct to reasonably believe that he or she is in imminent danger of death or great bodily harm. In such a case, the person engaging in the unlawful conduct is privileged to act in self-defense, but the person is not privileged to resort to the use of force intended or likely to cause death to the person's assailant unless the person reasonably believes he or she has exhausted every other reasonable means to escape from or otherwise avoid death or great bodily harm at the hands of his or her assailant.
The privilege lost by provocation may be regained if the actor in good faith withdraws from the fight and gives adequate notice thereof to his or her assailant.
A person who provokes an attack, whether by lawful or unlawful conduct, with intent to use such an attack as an excuse to cause death or great bodily harm to his or her assailant is not entitled to claim the privilege of self-defense.
The privilege of self-defense extends not only to the intentional infliction of harm upon a real or apparent wrongdoer, but also to the unintended infliction of harm upon a 3rd person, except that if the unintended infliction of harm amounts to the crime of first-degree or 2nd-degree reckless homicide, homicide by negligent handling of dangerous weapon, explosives or fire, first-degree or 2nd-degree reckless injury or injury by negligent handling of dangerous weapon, explosives or fire, the actor is liable for whichever one of those crimes is committed.
A person is privileged to defend a 3rd person from real or apparent unlawful interference by another under the same conditions and by the same means as those under and by which the person is privileged to defend himself or herself from real or apparent unlawful interference, provided that the person reasonably believes that the facts are such that the 3rd person would be privileged to act in self-defense and that the person's intervention is necessary for the protection of the 3rd person.
A person is privileged to use force against another if the person reasonably believes that to use such force is necessary to prevent such person from committing suicide, but this privilege does not extend to the intentional use of force intended or likely to cause death.
In this section “unlawful" means either tortious or expressly prohibited by criminal law or both.
Judicial Council Note, 1988: Sub. (3) is amended by conforming references to the statute titles as affected by this bill. [Bill 191-S]
When a defendant testified that he did not intend to shoot or use force, he could not claim self-defense. Cleghorn v. State, 55 Wis. 2d 466
, 198 N.W.2d 577
Sub. (2) (b) is inapplicable to a defendant if the nature of the initial provocation is a gun-in-hand confrontation of an intended victim by a self-identified robber. Under these circumstances the intended victim is justified in the use of force in the exercise of the right of self-defense. Ruff v. State, 65 Wis. 2d 713
, 223 N.W.2d 446
Whether a defendant's belief was reasonable under subs. (1) and (4) depends, in part, upon the parties' personal characteristics and histories and whether events were continuous. State v. Jones, 147 Wis. 2d 806
, 434 N.W.2d 380
Evidence of prior specific instances of violence that were known to the accused may be presented to support a defense of self-defense. The evidence is not limited to the accused's own testimony, but the evidence may not be extended to the point that it is being offered to prove that the victim acted in conformity with his or her violent tendencies. State v. Daniels, 160 Wis. 2d 85
, 465 N.W.2d 633
Imperfect self-defense contains an initial threshold element requiring a reasonable belief that the defendant was terminating an unlawful interference with his or her person. State v. Camacho, 176 Wis. 2d 860
, 501 N.W.2d 380
The reasonableness of a person's belief under sub. (1) is judged from the position of a person of ordinary intelligence and prudence in the same situation as the defendant, not a person identical to the defendant placed in the same situation as the defendant. A defendant's psycho-social history showing past violence toward the defendant is generally not relevant to this objective standard, although it may be relevant, as in spousal abuse cases, where the actors are the homicide victim and defendant. State v. Hampton, 207 Wis. 2d 369
, 558 N.W.2d 884
(Ct. App. 1996).
The right to resist unlawful arrest is not part of the statutory right to self-defense. It is a common law privilege that is abrogated. State v. Hobson, 218 Wis. 2d 350
, 577 N.W.2d 825
While there is no statutory duty to retreat, whether the opportunity to retreat was available goes to whether the defendant reasonably believed the force used was necessary to prevent an interference with his or her person. A jury instruction to that effect was proper. State v. Wenger, 225 Wis. 2d 495
, 593 N.W.2d 467
(Ct. App. 1999), 98-1739
When a defendant fails to establish a factual basis to raise self-defense, prior specific acts of violence by the victim have no probative value. The presentation of subjective testimony by an accused, going to a belief that taking steps in self-defense was necessary, is not sufficient for the admission of self-defense evidence. State v. Head, 2000 WI App 275
, 240 Wis. 2d 162
, 622 N.W.2d 9
