28 V.S.A. § 252a

(a) When the court imposes a sentence upon a defendant who has been convicted of an offense enumerated in section 204a of this title that includes a period of incarceration of more than one year to serve to be followed by probation, the court may make the probation contingent on the offender fulfilling specific stated conditions, such as taking part in treatment while incarcerated, and may modify, following a hearing pursuant to subsection (c) of this section, the conditions of probation if a violation has occurred. The court shall review the probation conditions imposed at the time of sentencing after the incarceration portion of the sentence has been served, and prior to the offender's release to probation. Such review shall include information about the offender developed after the date of sentencing, including information about the offender's incarceration period.

(b) For an offender whose probation is contingent on fulfilling conditions pursuant to subsection (a) of this section, the Department of Corrections shall prepare a prerelease probation report to the court at least 30 days prior to the release based upon information available to the Department. The prerelease probation report shall include the offender's degree of participation in treatment while incarcerated, whether conditions imposed under subsection (a) of this section were complied with, and other information relevant to the offender's release to the probationary sentence. The Department of Corrections shall provide a copy of the prerelease probation report to the attorney for the offender and the prosecuting attorney at the same time it provides the report to the court.

(c) If the Commissioner of Corrections believes the offender has violated a condition imposed under subsection (a) of this section, he or she may recommend a change to the original probation order. In this case, the court shall schedule a modification hearing prior to the release date. The court may modify the conditions or add further requirements as authorized by section 252 of this title. The offender shall have a reasonable opportunity to contest the modification prior to its imposition. The prosecuting attorney shall represent the State in connection with any proceeding held in accordance with this section.
