The Judicial Branch shall expand its contracted-for juvenile justice services to include a comprehensive system of graduated responses with an array of services, sanctions and secure placements available for the court and juvenile probation officers and other staff of the Court Support Services Division to use in order to provide individualized supervision, care, accountability and treatment to any child, as defined in section 46b-120, who has been convicted as delinquent, as described in section 46b-120. The court and juvenile probation officers and other staff of the Court Support Services Division shall apply such services and sanctions and make such secure placements in a manner consistent with public safety in order to (1) deter any such child from the commission of any further delinquent act, and (2) ensure that the safety of any other persons will not be endangered.
