INCHOATE CRIMES
939.30939.30Solicitation.
939.30(1)(1)Except as provided in sub. (2) and s. 961.455, whoever, with intent that a felony be committed, advises another to commit that crime under circumstances that indicate unequivocally that he or she has the intent is guilty of a Class H felony.
939.30(2)(2)For a solicitation to commit a crime for which the penalty is life imprisonment, the actor is guilty of a Class F felony. For a solicitation to commit a Class I felony, the actor is guilty of a Class I felony.
939.30 AnnotationProsecuting for solicitation under this section, rather than under s. 944.30 for prostitution, did not deny equal protection. Sears v. State, 94 Wis. 2d 128, 287 N.W.2d 785 (1980).
939.30 AnnotationSection 939.05 (2) (c) does not make renunciation or withdrawal a defense to the crime of solicitation. State v. Boehm, 127 Wis. 2d 351, 379 N.W.2d 874 (Ct. App. 1985).
939.30 AnnotationWhen “A” solicits “B” to solicit “A” to commit perjury, “A” is guilty of solicitation. State v. Manthey, 169 Wis. 2d 673, 487 N.W.2d 44 (Ct. App. 1992).
939.30 AnnotationThe crime of solicitation does not require that the actor know with certainty whether an injury will in fact result from the solicitee’s conduct. State v. Kloss, 2019 WI App 13, 386 Wis. 2d 314, 925 N.W.2d 563, 18-0651.
939.31939.31Conspiracy. Except as provided in ss. 940.43 (4), 940.45 (4) and 961.41 (1x), whoever, with intent that a crime be committed, agrees or combines with another for the purpose of committing that crime may, if one or more of the parties to the conspiracy does an act to effect its object, be fined or imprisoned or both not to exceed the maximum provided for the completed crime; except that for a conspiracy to commit a crime for which the penalty is life imprisonment, the actor is guilty of a Class B felony.
939.31 HistoryHistory: 1977 c. 173; 1981 c. 118; 1985 a. 328; 1995 a. 448.
939.31 AnnotationA conspiracy may be unilateral; a person can enter into a conspiracy to accomplish a criminal objective in which only the defendant has a criminal intent. State v. Sample, 215 Wis. 2d 487, 573 N.W.2d 187 (1998), 96-2184.
939.31 AnnotationWhen the object of a conspiracy is the commission of multiple crimes, separate charges and convictions for each intended crime are permissible. State v. Jackson, 2004 WI App 190, 276 Wis. 2d 697, 688 N.W.2d 688, 03-2066.
939.31 AnnotationThere is a distinction between conspiracy as a substantive inchoate crime under this section and conspiracy as a theory of prosecution for a substantive crime under s. 939.05 (2) (c). State v. Jackson, 2005 WI App 104, 281 Wis. 2d 137; 701 N.W.2d 42, 04-1603.
939.31 AnnotationThe agreement to commit a crime that is necessary for a conspiracy may be demonstrated by circumstantial evidence and need not be express; a tacit understanding of a shared goal is sufficient. The intent to commit the crime may be inferred from the person’s conduct. A stake in the venture is not a necessary element of the crime although evidence of a stake in the venture may be persuasive of the degree of the party’s involvement in the crime. State v. Routon, 2007 WI App 178, 304 Wis. 2d 480, 736 N.W.2d 530, 06-2557.
939.31 AnnotationA person may be a member of a conspiracy—in particular, a conspiracy to manufacture a controlled substance—based on the person’s sale of goods that are not illegal to sell or possess. One does not become a party to a conspiracy by aiding and abetting it, through sales of supplies or otherwise, unless the person knows of the conspiracy, the inference of which knowledge cannot be drawn from mere knowledge that the buyer will use the goods illegally. The gist of the conspiracy is the seller’s intent, when given effect by an overt act to further, promote, and cooperate in the buyer’s intended illegal use. There must be clear, unequivocal evidence of the seller’s knowledge of the buyer’s intended illegal use. State v. Routon, 2007 WI App 178, 304 Wis. 2d 480, 736 N.W.2d 530, 06-2557.
939.31 AnnotationUnder a unilateral conspiracy, a person who intends to accomplish the objects of the conspiracy is guilty even though the other members of the conspiracy never intended that a crime be committed. This same logic applies to the next step: that is, when the fulfillment of the conspiracy is not only highly unlikely, but is legally impossible. State v. Huff, 2009 WI App 92, 319 Wis. 2d 258, 769 N.W.2d 154, 08-2664.
939.31 AnnotationFor an act to performed by one of the conspirators in furtherance of the conspiracy, an overt act must be done toward the commission of the intended crime that must go beyond mere planning and agreement. However, the act need not, by itself, be an unlawful act or an attempt to commit the crime. If there was an act that was a step toward accomplishing the criminal objective, that is sufficient. In this case, the defendant’s act of communicating to a detective that cocaine was available for immediate delivery was such an overt act. State v. Peralta, 2011 WI App 81, 334 Wis. 2d 159, 800 N.W.2d 512, 10-0563.

939.32(1g)(1g)Maximum penalty. The maximum penalty for an attempt to commit a crime that is punishable under sub. (1) (intro.) is as follows:
939.32(1g)(a)(a) The maximum fine is one-half of the maximum fine for the completed crime.
939.32(1g)(b)1.1. If neither s. 939.62 (1) nor s. 961.48 is being applied, the maximum term of imprisonment is one-half of the maximum term of imprisonment, as increased by any penalty enhancement statute listed in s. 973.01 (2) (c) 2. a. and b., for the completed crime.
939.32(1g)(b)2.2. If either s. 939.62 (1) or 961.48 is being applied, the maximum term of imprisonment is determined by the following method:

939.32(1m)(a)1.1. Subject to the minimum term of extended supervision required under s. 973.01 (2) (d), if the crime is a classified felony and neither s. 939.62 (1) nor s. 961.48 is being applied, the maximum term of confinement in prison is one-half of the maximum term of confinement in prison specified in s. 973.01 (2) (b), as increased by any penalty enhancement statute listed in s. 973.01 (2) (c) 2. a. and b., for the classified felony.
939.32(1m)(a)2.2. Subject to the minimum term of extended supervision required under s. 973.01 (2) (d), if the crime is a classified felony and either s. 939.62 (1) or 961.48 is being applied, the court shall determine the maximum term of confinement in prison by the following method:
939.32(1m)(a)2.a.a. Multiplying by one-half the maximum term of confinement in prison specified in s. 973.01 (2) (b), as increased by any penalty enhancement statutes listed in s. 973.01 (2) (c) 2. a. and b., for the classified felony.
939.32(1m)(a)2.b.b. Applying s. 939.62 (1) or 961.48 to the product obtained under subd. 2. a.
939.32(1m)(b)(b) Maximum term of extended supervision for attempt to commit classified felony. The maximum term of extended supervision for an attempt to commit a classified felony is one-half of the maximum term of extended supervision for the completed crime under s. 973.01 (2) (d).
939.32(1m)(c)(c) Maximum term of confinement for attempt to commit unclassified felony or misdemeanor. The court shall determine the maximum term of confinement in prison for an attempt to commit a crime other than a classified felony by applying s. 973.01 (2) (b) 10. to the maximum term of imprisonment calculated under sub. (1g) (b).
939.32(2)(2)Misdemeanor computer crimes. Whoever attempts to commit a misdemeanor under s. 943.70 is subject to:

939.32(3)(3)Requirements. An attempt to commit a crime requires that the actor have an intent to perform acts and attain a result which, if accomplished, would constitute such crime and that the actor does acts toward the commission of the crime which demonstrate unequivocally, under all the circumstances, that the actor formed that intent and would commit the crime except for the intervention of another person or some other extraneous factor.
939.32 AnnotationThere is no crime of “attempted homicide by reckless conduct” since the completed offense does not require intent while any attempt must demonstrate intent. State v. Melvin, 49 Wis. 2d 246, 181 N.W.2d 490 (1970).
939.32 AnnotationAttempted first-degree murder was shown when only the fact of the gun misfiring and the action of the intended victim prevented completion of the crime. Austin v. State, 52 Wis. 2d 716, 190 N.W.2d 887 (1971).
939.32 AnnotationThe victim’s kicking of the defendant in the mouth and other resistance was a valid extraneous factor preventing the completion of a crime, an essential requirement for the crime of attempted rape. Adams v. State, 57 Wis. 2d 515, 204 N.W.2d 657 (1973).
939.32 AnnotationThe screams and struggles of an intended rape victim were an effective intervening extrinsic force not under the defendant’s control. Leach v. State, 83 Wis. 2d 199, 265 N.W.2d 495 (1978).
939.32 AnnotationThe failure to consummate the crime is not an essential element of criminal attempt under sub. (2). Berry v. State, 90 Wis. 2d 316, 280 N.W.2d 204 (1979).
939.32 AnnotationThe intervention of an extraneous factor is not an essential element of criminal attempt. Hamiel v. State, 92 Wis. 2d 656, 285 N.W.2d 639 (1979).
939.32 AnnotationTo prove attempt, the state must prove intent to commit a specific crime accompanied by sufficient acts to demonstrate unequivocally that it was improbable that the accused would have desisted of the accused’s own free will. State v. Stewart, 143 Wis. 2d 28, 420 N.W.2d 44 (1988).
939.32 AnnotationSubs. (1) and (2) enumerate all offenses that may be prosecuted as attempts. State v. Cvorovic, 158 Wis. 2d 630, 462 N.W.2d 897 (Ct. App. 1990).
939.32 AnnotationThe meaning of “have an intent to” in sub. (3) should be defined and interpreted in relation to all criminal statutes. State v. Weeks, 165 Wis. 2d 200, 477 N.W.2d 642 (Ct. App. 1991).
939.32 AnnotationWhen a sentence for an attempted crime is subject to repeater enhancement, the maximum penalty for the underlying crime is halved under sub. (1), then the enhancer is added to that penalty. State v. Bush, 185 Wis. 2d 716, 519 N.W.2d 645 (Ct. App. 1994).
939.32 AnnotationThe intervention of an extraneous factor that prevents the commission of a crime is irrelevant to an attempt to commit the crime unless the factor may negate the intent to commit the crime. That a defendant believed he was acquiring stolen property when the property was not actually stolen did not prevent the prosecution of the defendant for attempt to receive stolen property. State v. Kordas, 191 Wis. 2d 124, 528 N.W.2d 483 (Ct. App. 1995).
939.32 AnnotationAttempted felony murder, s. 940.03, does not exist. Attempt requires intent, and the crime of felony murder is complete without specific intent. State v. Briggs, 218 Wis. 2d 61, 579 N.W.2d 783 (Ct. App. 1998), 97-1558.
939.32 AnnotationThe conduct element of sub. (3) is satisfied when the accused engages in conduct that demonstrates that only a circumstance beyond the accused’s control could prevent the crime; that it has become too late to repent and withdraw. State v. Henthorn, 218 Wis. 2d 526, 581 N.W.2d 544 (Ct. App. 1998), 97-2235.
939.32 AnnotationSome crimes include attempt and cannot be combined with the general attempt statute. One cannot attempt to attempt to cause. State v. DeRango, 229 Wis. 2d 1, 599 N.W.2d 27 (Ct. App. 1999), 98-0642.
939.32 AnnotationNeither Melvin, 49 Wis. 2d 246 (1970), nor Briggs, 218 Wis. 2d 61 (1998), purport to establish a general rule or address whether possession crimes may be charged as attempted crimes. There is no general rule that a crime may be charged as an attempt only when the crime has intent as an element. Unlike crimes with no state of mind element, the felon in possession of a firearm offense requires proof of knowledge. This makes the offense amenable, even under Briggs, to be charged as an attempted crime. State v. Henning, 2013 WI App 15, 346 Wis. 2d 246, 828 N.W.2d 235, 10-2449.
subch. III of ch. 939SUBCHAPTER III
DEFENSES TO CRIMINAL LIABILITY
939.42939.42Intoxication. An intoxicated or a drugged condition of the actor is a defense only if such condition is involuntarily produced and does one of the following:
939.42(1)(1)Renders the actor incapable of distinguishing between right and wrong in regard to the alleged criminal act at the time the act is committed.
939.42(2)(2)Negatives the existence of a state of mind essential to the crime.
939.42 HistoryHistory: 1987 a. 399; 2013 a. 307.
939.42 AnnotationTo be relieved from responsibility for criminal acts, it is not enough for a defendant to establish that the defendant was under the influence of intoxicating beverages; the defendant must establish that degree of intoxication that means the defendant was utterly incapable of forming the intent requisite to the commission of the crime charged. State v. Guiden, 46 Wis. 2d 328, 174 N.W.2d 488 (1970).
939.42 AnnotationThis section does not afford a defense when drugs were taken voluntarily and the facts demonstrate that there was an intent to kill and conceal the crime. Gibson v. State, 55 Wis. 2d 110, 197 N.W.2d 813 (1972).
939.42 AnnotationEvidence of addiction was properly excluded as a basis for showing “involuntariness.” Loveday v. State, 74 Wis. 2d 503, 247 N.W.2d 116 (1976).
939.42 AnnotationThe intoxication instruction did not impermissibly shift the burden of proof to the accused. State v. Reynosa, 108 Wis. 2d 499, 322 N.W.2d 504 (Ct. App. 1982).
939.42 AnnotationA correct statement of the law under this section should be conveyed to the jury by instructing it that it must consider the evidence regarding whether the defendant was intoxicated at the time of the alleged offense. State v. Foster, 191 Wis. 2d 14, 528 N.W.2d 22 (Ct. App. 1995).
939.42 AnnotationIt is not a requirement of the defense of involuntary intoxication when intoxication is caused by prescription drugs that the defendant did not know of the drug’s intoxicating effect. Intoxication resulting from compliance with a physician’s advice will not be deemed voluntary just because the defendant was aware of potential adverse side effects. State v. Gardner, 230 Wis. 2d 32, 601 N.W.2d 670 (Ct. App. 1999), 98-2655.
939.42 AnnotationTo 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.
939.42 AnnotationCriminal Law: Alcoholism as a Defense. Herald. 53 MLR 445 (1970).
939.42 AnnotationDue Process and the Voluntary Intoxication Defense. Larson. Wis. Law. Feb. 2019.
939.43939.43Mistake.
939.43(1)(1)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.
939.43(2)(2)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.
939.43 AnnotationThe 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 (1974).
939.43 AnnotationMistake 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.
