Juvenile Justice Act Article 19

After a juvenile court undertakes a transfer, report, or request in accordance with the provisions of this Act, the juvenile investigation officer shall conduct a preliminary investigation into the delinquency-related behavior, character, experience, mental and physical conditions, family background, social environment, education background, and other necessary circumstances of the juvenile concerned, followed by filing a report within a designated time period, which must include concrete suggestions for handling the said matter.The results of an investigation conducted by a juvenile investigation officer shall not constitute the sole source of evidence for the purpose of establishing the facts.Where a juvenile investigation officer is summoned to appear before the court to give evidence on the results of an investigation or suggestions for handling a matter, the juvenile investigation officer that conducted the investigation referred to in paragraph 1 shall appear before the court in person, unless there is a justifiable cause of excusing himself/herself.A clerk shall make written records when the juvenile court questions the parties involved.
