Sentence credit
Wis. Stat. § 973.155
in effect(1)
(a) A convicted offender shall be given credit toward the service of his or her sentence for all days spent in custody in connection with the course of conduct for which sentence was imposed. As used in this subsection, “actual days spent in custody” includes, without limitation by enumeration, confinement related to an offense for which the offender is ultimately sentenced, or for any other sentence arising out of the same course of conduct, which occurs:
1. While the offender is awaiting trial;
2. While the offender is being tried; and
3. While the offender is awaiting imposition of sentence after trial.
(b) The categories in par. (a) and sub. (1m) include custody of the convicted offender which is in whole or in part the result of a probation, extended supervision or parole hold under s. 302.113 (8m), 302.114 (8m), 304.06 (3), or 973.10 (2) placed upon the person for the same course of conduct as that resulting in the new conviction.
(1m) A convicted offender shall be given credit toward the service of his or her sentence for all days spent in custody as part of a substance abuse treatment program that meets the requirements of s. 165.95 (3), as determined by the department of justice under s. 165.95 (9) and (10), for any offense arising out of the course of conduct that led to the person’s placement in that program.
(2) After the imposition of sentence, the court shall make and enter a specific finding of the number of days for which sentence credit is to be granted, which finding shall be included in the judgment of conviction. In the case of revocation of probation, extended supervision or parole, the department, if the hearing is waived, or the division of hearings and appeals in the department of administration, in the case of a hearing, shall make such a finding, which shall be included in the revocation order.
(3) The credit provided in sub. (1) or (1m) shall be computed as if the convicted offender had served such time in the institution to which he or she has been sentenced.
(4) The credit provided in sub. (1) shall include earned good time for those inmates subject to s. 302.43, 303.07 (3) or 303.19 (3) serving sentences of one year or less and confined in a county jail, house of correction or county reforestation camp.
(5) If this section has not been applied at sentencing to any person who is in custody or to any person who is on probation, extended supervision or parole, the person may petition the department to be given credit under this section. Upon proper verification of the facts alleged in the petition, this section shall be applied retroactively to the person. If the department is unable to determine whether credit should be given, or otherwise refuses to award retroactive credit, the person may petition the sentencing court for relief. This subsection applies to any person, regardless of the date he or she was sentenced.
(6) A defendant aggrieved by a determination by a court under this section may appeal in accordance with s. 809.30.
