At the end of or at any time during probation, the court may terminate probation by written order upon finding that there is no further need for supervision. The finding and order terminating probation may be entered in chambers in the absence of the juvenile and may be based on a report from the juvenile court counselor or, at the election of the court, the order may be entered with the juvenile present after notice and a hearing. (1979, c. 815, s. 1; 1998-202, s. 6; 2001-490, s. 2.25.)
