980.02 AnnotationA commitment under this chapter is not an extension of a commitment under ch. 975, and s. 975.12 does not limit the state’s ability to seek a separate commitment under this chapter of a person originally committed under ch. 975. State v. Post, 197 Wis. 2d 279, 541 N.W.2d 115 (1995), 94-2356.
980.02 AnnotationTo the extent that s. 938.35 (1) prohibits the admission of delinquency adjudications in proceedings under this chapter, it is repealed by implication. State v. Matthew A.B., 231 Wis. 2d 688, 605 N.W.2d 598 (Ct. App. 1999), 98-0229.
980.02 AnnotationIn a trial on a petition filed under sub. (2), the state has the burden to prove beyond a reasonable doubt that the petition was filed within 90 days of the subject’s release or discharge based on a sexually violent offense. State v. Thiel, 2000 WI 67, 235 Wis. 2d 823, 612 N.W.2d 94, 99-0316. See also State v. Thiel, 2001 WI App 52, 241 Wis. 2d 439, 625 N.W.2d 321, 99-0316.
980.02 AnnotationWhile a commitment under this chapter is civil, a court does not lose subject matter jurisdiction because a petition is filed under a criminal case number. State v. Pharm, 2000 WI App 167, 238 Wis. 2d 97, 617 N.W.2d 163, 98-1542.
980.02 AnnotationThis chapter provides its own procedures for commencing actions, and, as such, chs. 801 and 802 are inapplicable to the commencement of actions under this chapter. State v. Wolfe, 2001 WI App 136, 246 Wis. 2d 233, 631 N.W.2d 240, 99-2145.
980.02 AnnotationWhen a petition under this chapter was filed within 90 days of release from a sentence for an offense that was not a sexually violent offense, which was being served concurrently with a shorter sentence imposed for a sexually violent offense, the petition was timely. State v. Treadway, 2002 WI App 195, 257 Wis. 2d 467, 651 N.W.2d 334, 00-2957.
980.02 AnnotationThe state was not precluded from seeking a commitment under this chapter following the defendant’s parole revocation, even though the state had failed to prove that the defendant was a sexually violent person in need of commitment in a previous trial under this chapter that took place prior to the defendant’s parole. State v. Parrish, 2002 WI App 263, 258 Wis. 2d 521, 654 N.W.2d 273, 00-2524.
980.02 AnnotationThe circuit court had jurisdiction to conduct proceedings under this chapter involving an enrolled tribal member who committed the underlying sexual offense on an Indian reservation. State v. Burgess, 2003 WI 71, 262 Wis. 2d 354, 665 N.W.2d 124, 00-3074. See also Burgess v. Watters, 467 F.3d 676 (2006).
980.02 AnnotationUnder sub. (1), a request from the agency with jurisdiction and a subsequent decision by the Department of Justice not to file are prerequisites to a district attorney’s authority to file a petition under this chapter. State v. Byers, 2003 WI 86, 263 Wis. 2d 113, 665 N.W.2d 729, 99-2441.
980.02 AnnotationThe threshold decision of whether a petition should be filed remains in the hands of the agency with jurisdiction and outside of the political process. A district attorney may contact the agency to seek clarification of the evaluator’s determination under this chapter, to correct factual mistakes, to provide new or additional information, or to ask for a second opinion with a different evaluator. However, the agency can independently exercise its judgment and choose to ignore the district attorney’s efforts or to decline the district attorney’s request for a second evaluation if the agency determines that these efforts and requests are improperly politically motivated. State v. Bell, 2006 WI App 30, 289 Wis. 2d 275, 710 N.W.2d 525, 05-0890.
980.02 AnnotationThat the definition of “dangerousness” under this chapter lacks a temporal context limited to imminent danger does not render the statute unconstitutional. State v. Olson, 2006 WI App 32, 290 Wis. 2d 202, 712 N.W.2d 61, 04-0412.
980.02 AnnotationThis chapter does not require the dismissal of a pending commitment petition when the individual subject to the petition is incarcerated because of the revocation of either parole or extended supervision. Section 980.06 requires the circuit court to order the individual to be committed to the custody of the Department of Health Services for control, care, and treatment, but this chapter does not specify when that commitment must commence. While s. 980.06 sets forth the requirements for a proper commitment order, neither that section nor any other section of this chapter contains language stating when the individual requirements of that order must be satisfied. State v. Gilbert, 2012 WI 72, 342 Wis. 2d 82, 816 N.W.2d 215, 10-0594.
980.02 AnnotationIf a petition under this chapter satisfies the statutory requirements in this section at the time it is filed, it will not be invalidated if the conviction recited in the petition is later reversed. Subsequent facts that impact the status of the allegations in the petition may be relevant at trial under s. 980.05, but they will not invalidate a petition that met the requirements of this section at the time of filing. State v. Spaeth, 2014 WI 71, 355 Wis. 2d 761, 850 N.W.2d 93, 12-2170.
980.02 AnnotationApplying the common and accepted legal meanings of “released” and “discharged” as those terms are used in sub. (1m), a petition under this chapter must be filed either before the person is freed from confinement in prison or before the person’s entire sentence is completed. In this case, even assuming that the Department of Corrections was required to release the defendant on the defendant’s presumptive mandatory release (PMR) date, a petition under this chapter filed after the PMR date but while the defendant remained incarcerated was timely filed based on the language of sub. (1m), which permits filing a petition under this chapter before a person is “discharged.” State v. Stanley, 2014 WI App 89, 356 Wis. 2d 268, 853 N.W.2d 600, 13-2477.
