HCS HB 1182 -- JURISDICTION OF JUVENILE COURTS This bill allows a parent, legal guardian, or other person having legal custody of a child who is at least 15 years of age to petition a court to extend the jurisdiction of a juvenile court until the child is 18 years old. These provisions will not apply to a child who has received a high school diploma or its equivalent. Law enforcement officers, juvenile officers, school personnel, or court personnel will not be held civilly or criminally liable if their action or failure to act was based on a good faith belief that a child was not under the jurisdiction of a juvenile court.Copyright (c) Missouri House of Representatives
