In informally handled (nonpetitioned) cases, duly authorized court personnel, having screened the case, decide not to file a formal petition. Such personnel include judges, referees, probation officers, other officers of the court, and/or agencies statutorily designated to conduct petition screening for the juvenile court.
Formally handled (petitioned) cases are those that appear on the court calendar in response to the filing of a petition, complaint, or other legal instrument requesting the court to adjudicate a youth as a delinquent, status offender, or dependent child or to waive jurisdiction and transfer a youth to criminal court.
