Waiver to and conviction by district court — processing

1. Once jurisdiction over a child has been waived by the juvenile court as provided in section 232.45, for the alleged commission of a felony, and once a conviction is entered by the district court, for all other offenses, the clerk of the juvenile court shall immediately send a certified copy of the findings required by section 232.45, subsection 10, and the judgment of conviction, as applicable, to the department of public safety. The department shall maintain a file on each child who has previously been waived to or waived to and convicted by the district court in a prosecution as an adult. The file shall be accessible by law enforcement officers on a twenty-four hour per day basis. 2. Once a child sixteen years of age or older has been waived by the juvenile court to the district court, all subsequent criminal proceedings against the child for any delinquent act committed after the date of the waiver by the juvenile court shall begin in district court, notwithstanding sections 232.8 and 232.45. A copy of the findings required by section 232.45, subsection 10, shall be made a part of the record in the district court proceedings. However, upon acquittal or dismissal in district court of all waived offenses and all lesser included offenses of the waived offenses, the proceedings for any delinquent act committed by the child subsequent to such acquittal or dismissal shall begin in juvenile court. Any proceedings initiated in district court for a public offense committed by the child subsequent to the waiver by the juvenile court, but prior to any acquittal or dismissal of all waived offenses and lesser included offenses in district court, shall remain in district court. 3. If proceedings against a child sixteen years of age or older who has previously been waived to district court are mistakenly begun in the juvenile court, the matter shall be transferred to district court upon the discovery of the prior waiver, notwithstanding sections 232.8 and 232.45. 4. This section shall not apply to a child who was waived to the district court for the purpose of being prosecuted as a youthful offender.
