TN Code § 37-1-107 (2021)
2021 Tennessee Code|Title 37 - Juveniles|Chapter 1 - Juvenile Courts and Proceedings|Part 1 - General Provisions|§ 37-1-107. Magistrates

   The judge of the juvenile court may appoint one (1) or more suitable persons to act as magistrates at the pleasure of the judge. A magistrate shall be a member of the bar and may qualify and shall hold office at the pleasure of the judge. The compensation of a magistrate shall be fixed by the judge with the approval of the county legislative body or the pertinent governing body, and paid from public funds.   In any county with a population of not less than seventy-one thousand three hundred (71,300) nor more than seventy-one thousand four hundred (71,400), according to the 2000 federal census or any subsequent federal census, the child support magistrate appointed to serve the chancery court shall also serve the juvenile court.     The judge may direct that any case or class of cases over which the juvenile court has jurisdiction shall be heard in the first instance by the magistrate. These cases shall be conducted in the same manner as cases heard by the judge. In the conduct of the proceedings, the magistrate shall have the powers of a judge and shall have the same authority as the judge to issue any and all process.   Upon the conclusion of the hearing, the magistrate shall file an order. The magistrate shall also inform each party of the right to a hearing before the juvenile court judge, of the time limits within which a request for a hearing must be perfected, and of the manner in which to perfect the request.   Any party may, within ten (10) days after entry of the magistrate's order, file a request with the court for a de novo hearing by the judge of the juvenile court. The judge shall allow a hearing if a request for hearing is filed. No later than ten (10) days after the entry of the magistrate's order, the judge may, on the judge's own initiative, order a hearing of any matter heard before a magistrate. However, if the child pleads guilty or no contest before the magistrate in a delinquency or unruly proceeding, the child waives the right to request an adjudicatory hearing before the judge and the judge may not order an adjudicatory hearing in such proceeding. If the plea includes an agreement as to disposition, the child also waives the right to request a hearing before the judge regarding disposition and the judge may not order a hearing in such proceeding. Nothing herein alters the court's jurisdiction to hear post-dispositional issues, including, but not limited to, judicial reviews or collateral challenges. There shall be no hearing in any delinquent or unruly case in which the petition is dismissed by the magistrate after a hearing on the merits.  Unless the judge orders otherwise, the order of the magistrate shall be the order of the court pending the hearing.   If no hearing before the judge is requested, or if the right to the hearing is expressly waived by all parties within the specified time period, the magistrate's order becomes the order of the court. A party may appeal the order pursuant to § 37-1-159.   Any hearing by a magistrate on any preliminary matter shall be final and not reviewable by the judge of the juvenile court, except on the court's own initiative. The setting of bond in detention hearings and any matter that is a final adjudication of a child shall not be construed to be preliminary matters under this section and are reviewable by the judge of the juvenile court upon request or upon the court's own initiative, except as provided in this section.   All parties to the hearing before the magistrate shall be parties to a de novo hearing before the judge.
