Notwithstanding this subsection, the court may grant, ex parte, a motion brought by the probation officer to add further requirements if the requirements are immediately necessary to protect the safety of an individual or the public and if all reasonable efforts have been made to give written or oral notice to the person on supervised release.__Any requirements added pursuant to an ex parte motion do not take effect until written notice of the requirements, along with written notice of the scheduled date, time and place when the court will hold a hearing on the added requirements, is given to the person on supervised release.

4.__On application of the probation officer, or of the person on supervised release, or on its own motion, and if warranted by the conduct of the person, the court may terminate a period of supervised release and discharge the convicted person at any time earlier than that provided in the sentence made pursuant to subsections 1 and 2.__A termination and discharge may not be ordered upon the motion of the person on supervised release unless notice of the motion is given to the probation officer by the person on supervised release.__A termination and discharge relieves the person on supervised release of any obligations imposed by the sentence of supervised release.

5.__Any justice, in order to comply with section 1256, subsection 8, may terminate a period of supervised release that would delay commencement of a consecutive unsuspended term of imprisonment.__Any judge may also do so if that judge has jurisdiction over each of the sentences involved.

6.__The court may revoke a period of supervised release pursuant to section 1233.__If the court revokes a period of supervised release, the court may require the person to serve time in prison under the custody of the Department of Corrections.__This time in prison may equal all or part of the period of supervised release, without credit for time served on post-release supervision, but may not exceed 1/3 of the straight term of imprisonment imposed.
