Juvenile justice is a serious aspect; it is the area of criminal law applicable to persons young enough to be held responsible for a crime executed. In most states, the age for criminal culpability is set at 18 years. Juvenile law is mainly governed by state law and most states have enacted a juvenile code. The main goal of the juvenile justice system is rehabilitation rather than punishment.
Juveniles can be transferred into adult court if the juvenile court waives or relinquishes its jurisdiction.
State statutes creating juvenile courts and providing methods for dealing with juvenile delinquency have generally been upheld by courts as an acceptable extension of state police power to ensure the safety and welfare of children. The doctrine of parens patriae authorises the state to legislate for the protection, care, custody, and maintenance of children within its jurisdiction.
