Treaties between the federal government and Menominee tribe do not deprive the state of criminal subject matter jurisdiction over a crime committed by a Menominee outside the reservation. Sturdevant v. State, 76 Wis. 2d 247
, 251 N.W.2d 50
Trial courts do not have subject matter jurisdiction to convict defendants under unconstitutionally vague statutes. State ex rel. Skinkis v. Treffert, 90 Wis. 2d 528
, 280 N.W.2d 316
(Ct. App. 1979).
A fisherman who violated Minnesota and Wisconsin fishing laws while standing on the Minnesota bank of the Mississippi River was subject to Wisconsin prosecution. State v. Nelson, 92 Wis. 2d 855
, 285 N.W.2d 924

The state has exclusive jurisdiction over 2nd-offense drunk driving. A 2nd offender may not be charged as a 1st offender under a local ordinance. County of Walworth v. Rohner, 108 Wis. 2d 713
, 324 N.W.2d 682
An unlawful arrest does not deprive a court of personal jurisdiction over a defendant. State v. Smith, 131 Wis. 2d 220

, 548 N.W.2d 134
(Ct. App. 1996), 95-2469
Objections to subject matter jurisdiction that turn on a question of law may not be waived by a guilty plea, but objections to subject matter jurisdiction based on a factual dispute do not survive. State v. Bratrud, 204 Wis. 2d 445
, 555 N.W.2d 662
(Ct. App. 1995), 94-3402
A trial court did not lose subject matter jurisdiction over a count in a criminal complaint when an oral amendment of the count did not include one of the elements of the new offense. State v. Diehl, 205 Wis. 2d 1
, 555 N.W.2d 174
(Ct. App. 1996), 95-2444
A sentencing court is accorded incidental powers necessary to carry out its judicial functions and may modify an improper sentence, but it is not competent to enter a money judgment against the state for the recovery of improperly collected restitution under an improper sentence. State v. Minniecheske, 223 Wis. 2d 493
, 590 N.W.2d 17
(Ct. App. 1998), 98-1369
For purposes of jurisdictional analysis, the defendant father's concealment in Canada of a child taken from the child's mother in Wisconsin was inseparable from the consequences of the concealment in Wisconsin, thus giving a Wisconsin court jurisdiction under sub. (1) (c) to try the defendant for a violation of s. 948.31. State v. Inglin, 224 Wis. 2d 764
, 592 N.W.2d 666
(Ct. App. 1999), 97-3091
This section relates to both personal and territorial jurisdiction. When a trial court validly acquired territorial jurisdiction over the charged crime, it could not lose jurisdiction over a lesser-included crime. State v. Randle, 2002 WI App 116, 2002 WI App 116, 252 Wis. 2d 743
, 647 N.W.2d 324
If there is no serious evidentiary dispute that the trial court has territorial jurisdiction, a special instruction on territorial jurisdiction need not be given to the jury. A person may be prosecuted for doing an act outside this state that has a criminally proscribed consequence within the state. State v. Brown, 2003 WI App 34, 260 Wis. 2d 125
, 659 N.W.2d 110
The constituent elements of an offense under sub. (1) (a) are those elements of the criminal offense that the state is required to prove beyond a reasonable doubt in the prosecution of the offense. A constituent element of a criminal offense may be either the wrongful deed that comprises the physical component or the state of mind that the prosecution must prove that a defendant had. For 1st-degree homicide, sub. (1) (a) is satisfied upon proof that the defendant committed an act in Wisconsin manifesting the intent to kill. State v. Anderson, 2005 WI 54, 280 Wis. 2d 104
, 695 N.W.2d 731
Parties to crime. 939.05(1)(1)
Whoever is concerned in the commission of a crime is a principal and may be charged with and convicted of the commission of the crime although the person did not directly commit it and although the person who directly committed it has not been convicted or has been convicted of some other degree of the crime or of some other crime based on the same act.
A person is concerned in the commission of the crime if the person:
Intentionally aids and abets the commission of it; or
Is a party to a conspiracy with another to commit it or advises, hires, counsels or otherwise procures another to commit it. Such a party is also concerned in the commission of any other crime which is committed in pursuance of the intended crime and which under the circumstances is a natural and probable consequence of the intended crime. This paragraph does not apply to a person who voluntarily changes his or her mind and no longer desires that the crime be committed and notifies the other parties concerned of his or her withdrawal within a reasonable time before the commission of the crime so as to allow the others also to withdraw.
History: 1993 a. 486
It is desirable, but not mandatory, that an information refer to this section if the district attorney knows in advance that a conviction can only be based on participation and the court can instruct and the defendant can be convicted on the basis of this section in the absence of a showing of adverse effect on the defendant. Bethards v. State, 45 Wis. 2d 606
, 173 N.W.2d 634

, 191 N.W.2d 12

, 191 N.W.2d 12
An information charging the defendant with being a party to a crime need not set forth the particular subsection relied upon.

, 211 N.W.2d 421

, 249 N.W.2d 529
Defendants may be found guilty under sub. (2) if, between them, they perform all of the necessary elements of the crime with awareness of what the others are doing; each defendant need not be present at the scene of the crime. Roehl v. State, 77 Wis. 2d 398
, 253 N.W.2d 210

, 280 N.W.2d 288

The elements of aiding and abetting are undertaking conduct that will aid another in the execution of the crime and a conscious desire that the conduct will yield that aid. State v. Hecht, 116 Wis. 2d 605
, 342 N.W.2d 721
The jury need not unanimously agree as to in which of the alternative ways under sub. (2) a defendant has committed the offense under the party to the crime theory. While there may be distinctions between aiding abetting and conspiracy, the distinctions are often blurred. State v. Hecht, 116 Wis. 2d 605
, 342 N.W.2d 721
Testimony concerning a party to the crime defendant's whereabouts during planning sessions for the crime was not an alibi and did not require a notice of alibi under s. 971.23 (8). State v. Horenberger, 119 Wis. 2d 237
, 349 N.W.2d 692
Depending on the facts of the case, armed robbery can be a natural and probable consequence of a robbery. In that case, an aider and abettor need not have had actual knowledge that the principals would be armed. State v. Ivey, 119 Wis. 2d 591
, 350 N.W.2d 622
Sub. (2) (c) may be violated where the defendant solicits a 2nd person to procure a 3rd person to commit a crime. State v. Yee, 160 Wis. 2d 15
, 465 N.W.2d 260

, 516 N.W.2d 391
(1994), State v. Chambers, 183 Wis. 2d 316
, 515 N.W.2d 531

, 516 N.W.2d 399
(Ct. App. 1994).
There is a distinction between conspiracy as a substantive inchoate crime under s. 939.31 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
The unanimity requirement was satisfied when the jury unanimously found that the accused participated in the crime. Lampkins v. Gagnon, 710 F. 2d 374

A crime is conduct which is prohibited by state law and punishable by fine or imprisonment or both. Conduct punishable only by a forfeiture is not a crime.
Criminal conduct or contributory negligence of victim no defense.
It is no defense to a prosecution for a crime that the victim also was guilty of a crime or was contributorily negligent.
A jury instruction that a defrauded party had no duty to investigate fraudulent representations was correct. Lambert v. State, 73 Wis. 2d 590
, 243 N.W.2d 524
This section does not prevent considering the victim's negligence in relation to causation. This section only means that a defendant is not immune from prosecution merely because the victim has been negligent. State v. Lohmeier, 205 Wis. 2d 183
, 556 N.W.2d 90
