(1) Juvenile offenders
  When the police or other authority clear a juvenile offender aged14-19, excluding for cases with payment of non-penal fines for Road Traffic Act violations, the case is referred to a family court for offenses liable to a fine or lighter punishment, or to a public prosecutor for offenses for which they are liable to imprisonment or capital punishment (for the definition of juvenile offenders, juveniles of illegal behavior, and pre-delinquents, see Chapter 1 of this Part).
  After the referral, the public prosecutor must carry out an investigation and make a referral to a family court if any offense is suspected, or if any reason for a hearing at a family court is acknowledged even when there is no suspicion of any offense. When the public prosecutor refers the case to the family court, he/she can offer an opinion on the treatment of the juvenile.

(2) Pre-delinquents and juveniles of illegal behavior
  As for juveniles of illegal behavior and pre-delinquents under the age of 14, priority is given to measures under the Child Welfare Act. A family court may subject such juvenile to a hearing only when it receives a referral from a prefectural governor or a director of a child guidance center.
  Anyone who has discovered a pre-delinquent aged 14 or over, in principle, shall notify a family court as to the case. A police officer or a guardian may directly notify a child guidance center regarding the case if the pre-delinquent is under 18 years of age, as long as the police officer or guardian deems it more appropriate to handle the case first using measures under the Child Welfare Act than to directly notify or refer the case to a family court.
