(1)    When an inmate who is serving a sentence imposed under s. 973.01 and who has earned positive adjustment time under s. 302.113, 2009 stats., or under s. 304.06, 2009 stats., has served the confinement portion of his or her sentence less positive adjustment time earned between October 1, 2009, and August 3, 2011, he or she may petition the sentencing court to adjust the sentence under this section, based on the number of days of positive adjustment time the inmate claims that he or she has earned.

   (3)   Within 60 days of receipt of a petition filed under sub. (1), the sentencing court shall either deny the petition or hold a hearing and issue an order relating to the inmate’s sentence adjustment and release to extended supervision.

   (5)   If the court determines that the inmate has earned positive adjustment time, the court may reduce the term of confinement in prison by the amount of time remaining in the term of confinement in prison portion of the sentence, less up to 30 days, and shall lengthen the term of extended supervision so that the total length of the bifurcated sentence originally imposed does not change.

   (6)   An inmate who submits a petition under this section may not apply for adjustment of the same sentence under s. 973.195 for a period of one year from the date of the petition.
