Modification of probation is governed by the procedures contained in Title 17-A, section 1202, subsection 2. Termination of probation is governed by the procedures contained in Title 17-A, section 1202, subsection 3. Revocation of probation is governed by the procedures contained in Title 17-A, sections 1205, 1205-B, 1205-C and 1206, except that the provisions of those sections requiring a preliminary hearing do not apply and those provisions of Title 17-A, section 1206, subsection 7-A allowing a vacating of part of the suspension of execution apply only to a disposition under subsection 1, paragraph G or H; however, a disposition under subsection 1, paragraph F may be modified to a disposition under subsection 1, paragraph H. Whenever a revocation of probation results in the imposition of a disposition under subsection 1, paragraph F or a period of detention under subsection 1, paragraph H, the court shall determine whether reasonable efforts have been made to prevent or eliminate the need for removal of the juvenile from the juvenile's home or that no reasonable efforts are necessary because of the existence of an aggravating factor as defined in Title 22, section 4002, subsection 1-B and whether continuation in the juvenile's home would be contrary to the welfare of the juvenile.__This determination does not affect whether the court orders a particular disposition upon a revocation of probation. If the juvenile is being detained for an alleged violation of probation, the court shall review within 48 hours following the detention, excluding Saturdays, Sundays and legal holidays, the decision to detain the juvenile. Following that review, the court shall order the juvenile's release unless the court finds that there is probable cause to believe that the juvenile has violated a condition of probation and finds, by a preponderance of the evidence, that continued detention is necessary to meet one of the purposes of detention under section 3203-A, subsection 4, paragraph C. Whenever a court orders continued detention, the court shall determine whether reasonable efforts have been made to prevent or eliminate the need for removal of the juvenile from the juvenile's home or that no reasonable efforts are necessary because of the existence of an aggravating factor as defined in Title 22, section 4002, subsection 1-B and whether continuation in the juvenile's home would be contrary to the welfare of the juvenile.__This determination does not affect whether the court orders continued detention.
