Deciding when a seizure occurs is important because the moment of a seizure limits what facts a court may consider in determining the existence of reasonable suspicion for that seizure. The Mendenhall, 446 U.S. 544, test applies when the subject of police attention is either subdued by force or submits to a show of authority. Where, however, a person flees in response to a show of authority, Hodari D., 499 U.S. 279, governs when the seizure occurs. The Hodari D. test does not supersede the Mendenhall test, it supplements it. State v. Young, 2006 WI 98, 294 Wis. 2d 1, 717 N.W.2d 729, 03-2968.

An anonymous tip, whose indicia of reliability was debatable, along with behavior observed by the officer at the scene and deemed suspicious provided reasonable suspicion to justify a Terry stop. Terry holds that the police are not required to rule out the possibility of innocent behavior before initiating a Terry stop. Suspicious conduct by its very nature is ambiguous, and the principle function of the investigative stop is to quickly resolve that ambiguity. State v. Patton, 2006 WI App 235, 297 Wis. 2d 415, 724 N.W.2d 347, 05-3084.

There is a difference between police informers, who usually themselves are criminals, and citizen informers that calls for different means of assessing credibility. A citizen informant's reliability is subject to a much less stringent standard. Citizens who purport to have witnessed a crime are viewed as reliable, and police are allowed to act accordingly although other indicia of reliability have not yet been established. That an informant does not give some indication of how he or she knows about the suspicious or criminal activity reported bears significantly on the reliability of the information. State v. Kolk, 2006 WI App 261, 298 Wis. 2d 99, 726 N.W.2d 337, 06-0031.

To have a 4th Amendment claim an individual must have standing. Standing exists when an individual has a reasonable expectation of privacy; which requires meeting a two-prong test: 1) whether the individual's conduct exhibited an actual, subjective, expectation of privacy in the area searched and the item seized; and 2) if the individual had the requisite expectation of privacy, whether the expectation of privacy was legitimate or justifiable. State v. Bruski, 2007 WI 25, 299 Wis. 2d 177, 727 N.W.2d 503, 05-1516.

In considering whether an individual's expectation of privacy was legitimate or justifiable, the following may be relevant: 1) whether the accused had a property interest in the premises; 2) whether the accused was lawfully on the premises; 3) whether the accused had complete dominion and control and the right to exclude others; 4) whether the accused took precautions customarily taken by those seeking privacy; 5) whether the property was put to some private use; and 6) whether the claim of privacy was consistent with historical notions of privacy. State v. Bruski, 2007 WI 25, 299 Wis. 2d 177, 727 N.W.2d 503, 05-1516.

Whether an individual may have a reasonable expectation of privacy in personal property found inside a vehicle that he or she does not have a reasonable expectation of privacy in is not governed by a bright-line rule. Principles pertinent to whether there was a reasonable expectation of privacy are that: 1) personal property found in vehicles is treated differently than personal property found in dwellings, there being a lesser expectation of privacy in vehicles; 2) neither ownership nor possession of an item alone establishes a reasonable expectation of privacy; 3) an individual's expectation of privacy in the space, rather than concepts of property law, is critical. State v. Bruski, 2007 WI 25, 299 Wis. 2d 177, 727 N.W.2d 503, 05-1516.

When the defendant was only suspected of driving a vehicle with a suspended registration for an emissions violation and failing to signal for a turn, violations in no way linked to criminal activity or weapons possession, and when the only purported basis for a protective search was a single, partially obscured movement of the defendant in his vehicle that the officers observed from their squad car, the behavior observed by the officers was not sufficient to justify a protective search of Johnson's person and his car. State v. Johnson, 2007 WI 32, 299 Wis. 2d 675, 729 N.W.2d 182, 05-0573.

Weaving within a single traffic lane does not alone give rise to the reasonable suspicion necessary to conduct an investigative stop of a vehicle. The reasonableness of a stop must be determined based on the totality of the facts and circumstances. State v. Post, 2007 WI 60, 301 Wis. 2d 1, 733 N.W.2d 634, 05-2778.

A private party's discovery, and subsequent disclosure to law enforcement, of contraband is not prohibited by the 4th amendment when there is no reasonable expectation of privacy in dealings with the private party. One does not generally have a reasonable expectation of privacy when delivering property to a private shipping company, particularly when the shipping company posts a sign reserving its right to inspect parcels left with it for shipping. State v. Sloan, 2007 WI App 146, 303 Wis. 2d 438, 736 N.W.2d 189, 06-1271.

An employee of a private company is not acting on behalf of the government and is free to disclose a package and material to law enforcement. Law enforcement, without a warrant, can properly replicate the search the employee has already conducted. By otherwise replicating the private-party search, police did not exceed the scope of the private search by conducting a field test for drugs. State v. Sloan, 2007 WI App 146, 303 Wis. 2d 438, 736 N.W.2d 189, 06-1271.

The emergency doctrine permits officers investigating a kidnapping case to conduct a warrantless search if the officers possess an objectively reasonable belief that the particular search will result in finding the victim or evidence leading to the victim's location. Police need not delay rescue where they reasonably believe that a kidnap victim is being held and a search of the premises will lead to the victim or to information about the victim's whereabouts; time is of the essence. State v. Larsen, 2007 WI App 147, 302 Wis. 2d 718, 736 N.W.2d 211, 06-1396.

One common factor in some cases in which courts have concluded that the officers did not have a justifiable basis for conducting a protective sweep has been that the protective search takes place after the traffic investigation has been completed. A protective sweep was justified when there were specific facts that demonstrated that the officers' primary concern was indeed weapons and safety and the protective search was the first thing the officers did, and was not an afterthought. State v. Alexander, 2008 WI App 9, ___ Wis. 2d ___, ___ N.W.2d ___, 07-0403.

The fact that that an officer told the defendant that she was under arrest did not necessarily establish an arrest when immediately after making that statement the officer told the defendant that she would be issued a citation and then would be free to go. Although the statements are contradictory, the assurance that the defendant would be issued a citation and released would lead a reasonable person to believe he or she was not in custody. Under those circumstances a search of the defendant was not incident to a lawful arrest and, as such, unlawful. State v. Marten-Hoye, 2008 WI App 19, ___ Wis. 2d ___, ___ N.W.2d ___, 06-1104.

Under Belton, 453 U.S. 454, when a police officer has made a lawful custodial arrest of the occupant of an automobile, the officer may, as a contemporaneous incident of that arrest, search the passenger compartment of the automobile. An officer may assume that the interior of an automobile is within the reach of a defendant when the defendant is still at the scene of an arrest, but the defendant is not physically in the vehicle. A literal reading of the term "immediate control" has plainly been rejected. State v. Littlejohn, 2008 WI App 45, ___ Wis. 2d___, 747 N.W.2d 712, 07-0900.

That an officer is to be "totally divorced," from law enforcement functions when acting in a community caretaker function that justifies a warrantless search cannot mean that an officer must have subjectively ruled out all possibility of criminal activity. Police commonly act as community caretakers in situations where it remains reasonably possible that they will discover some criminal activity. State v. Kramer, 2008 WI App 62, ___ Wis. 2d___, ___ N.W.2d ___, 07-1834.

The potential availability of an innocent explanation does not prohibit an investigative stop. If any reasonable inference of wrongful conduct can be objectively discerned, notwithstanding the existence of innocent inferences that could be drawn, officers have the right to temporarily detain an individual for the purpose of inquiry. State v. Limon, 2008 WI App 77, ___ Wis. 2d___, ___ N.W.2d ___, 07-1578.

Although Terry provides only for an officer to conduct a carefully limited search of the outer clothing in an attempt to discover weapons that might be used to assault the officer, under the circumstances of this case, the search was properly broadened to encompass the opening of the defendant's purse, which was essentially an extension of her person where the purse was accessible by her. State v. Limon, 2008 WI App 77, ___ Wis. 2d___, ___ N.W.2d ___, 07-1578.

Because of the limited intrusion resulting from a dog sniff for narcotics and the personal interests that Art. I, s. 11 were meant to protect, a dog sniff around the outside perimeter of a vehicle located in a public place is not a search under the Wisconsin Constitution. The 78 seconds during which the dog sniff occurred was a not an unreasonable incremental intrusion upon the defendant's liberty. State v. Arias, 2008 WI 84, ___ Wis. 2d ___, ___ N.W.2d ___, 06-0974.

The "search incident to arrest" exception to the 4th amendment warrant requirement holds that a lawful arrest creates a situation justifying a contemporaneous, warrantless search of the arrestee's person and the area within his or her immediate control. It is reasonable to search an area near the arrestee, but not an area so broad as to be unrelated to the protective purposes of the search. Although a bedroom might be considered within the defendant's immediate presence or control the search of a bedroom was not a search incident to arrest after the defendant had been removed from the home as the defendant could not have gained possession of a weapon or destructible evidence. State v. Sanders, 2008 WI 85, ___ Wis. 2d ___, ___ N.W.2d ___, 06-2060.

Reasonable suspicion was not obviated by the fact that 15 minutes passed between the time of a stop and a protective search when the defendant was kept under continuous surveillance. The passage of time can be a factor in the totality of circumstances, but it is not likely to be a determinative factor in establishing or eliminating reasonable suspicion for a frisk. State v. Sumner, 2008 WI 94, ___ Wis. 2d ___, ___ N.W.2d ___, 06-0102.

The standing of a guest to challenge a search is measured by the guest's relationship to the property and the host. When a person claims guest status, the analysis examines the evidence in light of: 1) whether the guest's use of the premises was for a purely commercial purpose; 2) the duration of the guest's stay; and 3) the nature of the guest's relationship to the host. The defendant did not have standing when there was little evidence of the duration or closeness of the defendant's friendship with the property owner, the defendant did not have a long-term relationship to the place andnot an overnight guest, and at the time of the search, used it for a largely commercial purpose. State v. Fox, 2008 WI App 136, ___ Wis. 2d ___, ___ N.W.2d ___, 07-0685.

The defendant did not have standing to assert a 4th amendment violation based on an officer unlocking the door of the public restroom the defendant occupied. The defendant's expectation of privacy was not reasonable when, while his initial use of the restroom was for its intended purpose, he continued to have the private use of the locked restroom for at least 25 minutes without responding to knocking and while dozing off. State v. Neitzel, 2008 WI App 143, ___ Wis. 2d ___, ___ N.W.2d ___, 07-2346.

A warrantless, non-exigent, felony arrest in public was constitutional despite the opportunity to obtain a warrant. United States v. Watson, 423 U.S. 411.

When a driver was stopped because of expired license plates, a police order to get out of the car was reasonable and a subsequent "pat down" based on an observed bulge under the driver's jacket resulted in the legal seizure of an unlicensed revolver. Pennsylvania v. Mimms, 434 U.S. 106 (1977).

A burning building clearly presents an exigency rendering a warrantless entry reasonable, and fire officials need no warrant to remain in a building for a reasonable time to investigate the cause of the fire after it is extinguished. Michigan v. Tyler, 436 U.S. 499 (1978)

The warrantless installation of a pen register, that recorded telephone numbers called but not the contents of the calls, did not violate the 4th amendment. Smith v. Maryland, 442 U.S. 735 (1979).

A warrantless search of a suitcase in the trunk of a taxi was unconstitutional. Arkansas v. Sanders, 442 U.S. 753 (1979).

Police may not make a warrantless, nonconsensual entry into a suspect's home in order to make a routine felony arrest. Payton v. New York, 445 U.S. 573 (1980).

That police had lawful possession of pornographic film boxes did not give them authority to search their contents. Walter v. United States, 447 U.S. 649 (1980).

The search of a jacket lying in the passenger compartment of a car was incident to a lawful custodial arrest that justified the infringement of any privacy interest the arrestee may have had. New York v. Belton, 453 U.S. 454 (1981).

An officer who accompanied an arrestee to the arrestee's residence to obtain identification properly seized contraband in plain view. Washington v. Chrisman, 455 U.S. 1 (1982).

Officers who have legitimately stopped an automobile and who have probable cause to believe contraband is concealed somewhere within it may conduct a warrantless search of the vehicle as thorough as could be authorized by warrant. United States v. Ross, 456 U.S. 798 (1982).

When an officer, after stopping a defendant's car at a routine driver's license checkpoint, saw a tied-off party balloon in plain sight, the officer had probable cause to believe the balloon contained an illicit substance. Hence, a warrantless seizure of the balloon was legal. Texas v. Brown, 460 U.S. 730 (1983).

A warrantless search by arson investigators of the defendant's fire-damaged home that was not a continuation of an earlier search was unconstitutional. Michigan v. Clifford, 464 U.S. 287 (1984).

When a damaged shipping package was examined by company employees who discovered white powder, a subsequent warrantless field test by police was constitutional. U.S. v. Jacobsen, 466 U.S. 109 (1984).

The "open fields" doctrine is discussed. Oliver v. U.S. 466 U.S. 170 (1984).

The warrantless, nighttime entry of the defendant's home for arrest for a civil, nonjailable traffic offense was not justified under the "hot pursuit" doctrine or the preservation of evidence doctrine. Welsh v. Wisconsin, 466 U.S. 740 (1984).

School officials need not obtain a warrant before searching a student. The legality of the search depends on the reasonableness, under all circumstances, of the search. New Jersey v. T. L. O. 469 U.S. 325 (1985).

When officers were entitled to seize packages in a vehicle and could have searched them immediately without a warrant, a warrantless search of the packages 3 days later was reasonable. United States v. Johns, 469 U.S. 478 (1985).

The vehicle exception for warrantless searches applies to motor homes. California v. Carney, 471 U.S. 386 (1985).

The good faith exception to the exclusionary rule applies when an officer reasonably relies upon a statute allowing a warrantless administrative search that was subsequently ruled unconstitutional. Illinois v. Krull, 480 U.S. 340 (1987).

A protective sweep of a residence in conjunction with an arrest is permissible if police reasonably believe that the area harbors an individual posing a danger to officers or others. Maryland v. Buie, 494 U.S. 325, 108 L. Ed. 2d 276 (1990).

Inadvertence is not a necessary condition to a "plain view" seizure. Horton v. California, 496 U.S. 128, 110 L. Ed. 2d 112 (1990).

For a seizure of a person to occur there must either be an application of force, however slight, or when force is absent, submission to an officer's "show of authority." California v. Hodari D. 499 U.S. 279, 113 L. Ed. 690 (1991).

A determination of probable cause made within 48 hours of a warrantless arrest generally meets the promptness requirement. If a hearing is held more than 48 hours following the arrest the burden shifts to the government to demonstrate an emergency or extraordinary circumstances. County of Riverside v. McLaughlin, 500 U.S. 44, 114 L. Ed. 2d 49 (1991).

There shall be one rule governing all automobile searches. The police may search the car and all containers within it without a warrant when they have probable cause to believe contraband or evidence is contained in either. California v. Acevedo, 500 U.S. 565, 114 L. Ed. 2d 619 (1991).

If during a lawful weapons pat down an officer feels an object whose contours or mass makes its identity immediately apparent, there has been no invasion of privacy beyond that already authorized. Minnesota v. Dickerson, 508 U.S. 366, 124 L. Ed. 2d 334 (1993).

An officer making a traffic stop may order passengers to get out of the vehicle pending the completion of the stop. Maryland v. Wilson, 519 U.S. 408, 137 L. Ed. 2d 41 (1997).

Persons observed through a window in a home where they were not overnight guests but were present for a short period to engage in a primarily commercial illegal drug transaction, had no expectation of privacy in the home and the observation of those persons was not a constitutionally prohibited search. Minnesota v. Carter, 525 U.S. 83, 142 L. Ed. 2d 373 (1998).

The issuance of a traffic citation without an arrest did not authorize a full search of the vehicle. Knowles v. Iowa, 525 U.S. 113, 142 L. Ed. 2d 492 (1998).

When there is probable cause to search a vehicle for contraband officers may examine containers in the vehicle without a showing of individualized probable cause for each container. The container may be searched whether or not it's owner is present as a passenger, or otherwise, because it may contain contraband that the officers reasonably believe is in the car. Wyoming v. Houghton, 526 U.S. 295, 143 L. Ed. 2d 408 (1999).

Police need not obtain a warrant before seizing an automobile from a public place when there is probable cause to believe that the vehicle is forfeitable contraband. Florida v. White, 526 U.S. 559, 143 L. Ed. 2d 748 (1999).

The exception to the requirement of a warrant for automobiles does not require a separate finding of exigency, in addition to a finding of probable cause. Maryland v. Dyson, 527 U.S. 465, 144 L. Ed. 2d 442 (1999).

When there is probable cause to search a motor vehicle, the search is not unreasonable if the search is based on facts that would justify the issuance of a warrant, although a warrant was not obtained. No separate finding of exigent circumstances is required. Maryland v. Dyson, 527 U.S. 465, 144 L. Ed. 2d 442 (1999).

There is no murder scene exception to the warrant requirement. Flippo v. West Virginia, 528 U.S. 11, 145 L. Ed. 2d 16 (1999).

Nervous, evasive behavior is a pertinent factor in determining reasonable suspicion. Headlong flight is the consummate act of evasion. Illinois v. Wardlow, 528 U.S. 119, 145 L. Ed. 2d 570 (2000).

An anonymous tip that a person is carrying a gun, without more, is insufficient to justify a police officer's stop and frisk of a person. The tip must bear indicia of reliability. Reasonable suspicion requires that a tip be reliable in its assertion of criminal activity, not just in its tendency to to identify a person. Florida v. J.L. 529 U.S. 266, 146 L. Ed. 2d 254 (2000).

Stopping vehicles at highway checkpoints without any individualized suspicion to interdict illegal drugs was an unreasonable seizure under the 4th amendment because the primary purpose was to uncover evidence of ordinary criminal wrongdoing, unlike checkpoints to check for drunk driving or illegal immigrants. City of Indianapolis v. Edmond, 531 U.S. 32, 148 L. Ed. 2d 333 (2000).

The police acted reasonably when, with probable cause to believe that the defendant had hidden drugs in his home, they prevented the man from entering the home for about 2 hours until a search warrant could be obtained. Illinois v. McArthur, 531 U.S. 326, 148 LEd2d 838 (2001).

A state hospital could not test maternity patients for cocaine and then turn the results over to law enforcement authorities without patient consent. The interest of using the threat of criminal sanctions to deter pregnant women from using cocaine does not justify a departure from the rule that a nonconsensual search is unconstitutional if not authorized by a warrant. Ferguson v. City of Charleston, 525 U.S. 67, 149 LEd 2d 205 (2001).

If an officer has probable cause to believe a person has committed even a very minor criminal offense that does not breach the peace, the officer may, without violating the 4th amendment, arrest the offender without the need to balance the circumstances involved in the particular situation. Atwater v. City of Lago Vista, 532 U.S. 318, 149 L. Ed. 2d 549 (2001)

Obtaining, by sense-enhancing technology like infrared imaging, information regarding the interior of a home that could otherwise not be obtained without physical intrusion into a constitutionally protected area is a search presumptively unreasonable without a warrant. Kyllo v. U.S. 533 U.S. 27, 150 L. Ed. 2d 94 (2001).

A warrantless search of a probationer's residence founded on reasonable suspicion of criminal activity and authorized as a condition of probation was reasonable. Such a search is not restricted to monitoring whether the probationer is complying with probation restrictions. U.S. v. Knights, 534 U.S. 112, 151 L. Ed. 2d 497 (2001).

Police officers may approach bus riders at random to ask questions and to request consent to search luggage without advising the passengers of their right to not cooperate. U.S. v. Drayton, 536 U.S. 194, 153 L. Ed. 2d 242 (2002).

A school district policy of requiring all participants in competitive extracurricular activities to submit to drug testing was a reasonable means of furthering the district's interest in preventing drug use among students and was not an unreasonable search. Board of Education of Independent School District. No. 92 of Pottawatomie County v. White, 536 U.S. 822, 153 L. Ed. 2d 735 (2002).

A highway checkpoint where police stopped motorists to ask them for information about a recent hit-and-run was reasonable. The arrest of a drunk driver arrested when his vehicle swerved nearly hitting an officer at the checkpoint was constitutional. Illinois v. Lidster, 540 U.S. 419, 157 L. Ed 2d 843, 124 S. Ct. 885 (2004).

When a police officer has made a lawful custodial arrest of an occupant of an automobile, the 4th amendment allows the officer to search the passenger compartment of that vehicle as a contemporaneous incident of arrest whether the officer makes contact with the occupant while the occupant is inside the vehicle, or when the officer first makes contact with the arrestee after the latter has exited the vehicle. Thornton v. U.S. 541 U.S. 615, 158 L. Ed 2d 905, 124 S. Ct. 2127 (2004).

The principles of Terry permit a state to require a suspect to disclose his or her name in the course of a Terry stop and allow imposing criminal penalties for failing to do so. Hiibel v. Sixth Judicial District Court of Nevada, Humboldt County, 542 U.S. 177, 159 L. Ed 2d 292, 124 S. Ct. 2451 (2004).

The 4th amendment does not requires reasonable, articulable suspicion to justify using a drug-detection dog to sniff a vehicle during a legitimate traffic stop. The use of a well-trained narcotics-detection dog that does not expose noncontraband items that otherwise would remain hidden from public view during a lawful traffic stop, generally does not implicate legitimate privacy interests. Illinois v. Caballes, 543 U.S. 405, 160 L. Ed. 2d 842, 125 S. Ct. 834 (2004).

Police may enter a home without a warrant when they have an objectively reasonable basis for believing that an occupant is seriously injured or imminently threatened with such injury. An action is reasonable under the 4th amendment, regardless of the individual officer's state of mind, "as long as the circumstances, viewed objectively, justify the action. Brigham City v. Stuart, 547 U.S. 398, 164 L. Ed. 2d 650, 126 S. Ct. 1943 (2006).

The 4th Amendment does not prohibit a police officer from conducting a suspicionless search of a parolee. Samson v. California, 547 U.S. 843, 165 L. Ed. 2d 250, 126 S. Ct. 2193 (2006).

Warrantless arrests for crimes committed in the presence of an arresting officer are reasonable under the U.S. constitution, and while states are free to regulate such arrests however they desire, state restrictions do not alter the 4th Amendment's protections. Virginia v. Moore, 553 U. S. ___, 170 L. Ed. 2d 559, 128 S. Ct. 1598 (2008).

State v. Seibel: Wisconsin Police Now Need Only a Reasonable Suspicion to Search a Suspect's Blood Incident to an Arrest. Armstrong. 1993 WLR 563.

But What of Wisconsin's Exclusionary Rule? The Wisconsin Supreme Court Accepts Apparent Authority to Consent as Grounds for Warrantless Searches. Schmidt. 83 MLR 299.

But What of Wisconsin's Exclusionary Rule? The Wisconsin Supreme Court Accepts Apparent Authority to Consent as Grounds for Warrantless Searches. Schmidt. 83 MLR 299 (1999).

I,12 Attainder; ex post facto; contracts. Section 12. No bill of attainder, ex post facto law, nor any law impairing the obligation of contracts, shall ever be passed, and no conviction shall work corruption of blood or forfeiture of estate.

Section 45.37 (9), Stats. 1963, constituted a contract as to the property an applicant for admission to the Grand Army Home had to surrender, and to apply a later amendment would be unconstitutional. Estate of Nottingham, 46 Wis. 2d 580, 175 N.W.2d 640.

Although the obligation of a contract is not an absolute right but one that may yield to the compelling interest of the public, the public purpose served by a law mandating rent reductions due to property tax relief is not so vital so as to permit such an impairment of contract. State ex rel. Bldg. Owners v. Adamany, 64 Wis. 2d 280, 219 N.W.2d 274.

Retroactive application of s. 57.06, 1987 stats. [now s. 304.06], as amended in 1973, increasing the period to be served by state prison inmates imposed an additional penalty and violated the prohibition against ex post facto legislation. State ex rel. Mueller v. Powers, 64 Wis. 2d 643, 221 N.W.2d 692.

The legislative preclusion against the State Medical Society's divesting itself of control of ch. 148, disability plans did not constitute any impairment of the society's charter because: 1) the grant of ch. 148 powers is permissive and voluntarily exercised by the society; 2) the ch. 148 grant is in the nature of a franchise rather than a contract and cannot be viewed as unalterable or it would constitute a delegation of inalienable legislative power; and 3) the constitutional interdiction against statutes impairing contracts does not prevent the state from exercising its police powers for the common good. State Medical Society v. Comm. of Insurance, 70 Wis. 2d 144, 233 N.W.2d 470.

When a probation statute was amended after a crime was committed but before the accused pled guilty and was placed on probation, application of the amended statute to probation revocation proceedings offended the ex post facto clause. State v. White, 97 Wis. 2d 517, 294 N.W.2d 36 (Ct. App. 1979).

A challenge to legislation must prove: 1) the legislation impairs an existing contractual relationship; 2) the impairment is substantial; and 3) if substantial, the impairment is not justified by the purpose of the legislation. Reserve Life Ins. Co. v. La Follette, 108 Wis. 2d 637, 323 N.W.2d 173 (Ct. App. 1982).

The ex post facto prohibition applies to judicial pronouncements as well as legislative acts. The question to be addressed is whether the new law criminalizes conduct that was innocent when committed. State v. Kurzawa, 180 Wis. 2d 502, 509 N.W.2d 712 (1993).

Legislation creating penalty enhancers resulting from convictions prior to the effective date does not run afoul of the ex post facto clause. State v. Schuman, 186 Wis. 2d 213, 520 N.W.2d 107 (Ct. App. 1994).
