(b) Each participating district attorney’s office shall do all of the following:

(1) File petitions based on the most serious provable offenses of each arrest of a serious habitual offender.

(2) Use all reasonable prosecutorial efforts to resist the release, where appropriate, of the serious habitual offender at all stages of the prosecution.

(3) Seek an admission of guilt on all offenses charged in the petition against the offender. The only cases in which the prosecutor may request the court to reduce or dismiss the charges shall be cases in which the prosecutor decides there is insufficient evidence to prove the people’s case, the testimony of a material witness cannot be obtained or a reduction or dismissal will not result in a substantial change in sentence. In those cases, the prosecutor shall file a written declaration with the court stating the specific factual and legal basis for such a reduction or dismissal and the court shall make specific findings on the record of its ruling and the reasons therefor.

(4) Vertically prosecute all cases involving serious habitual offenders, whereby the prosecutor who makes the initial filing decision or appearance on such a case shall perform all subsequent court appearances on that case through its conclusion, including the disposition phase.

(5) Make all reasonable prosecutorial efforts to persuade the court to impose the most appropriate sentence upon such an offender at the time of disposition. As used in this paragraph, “most appropriate sentence” means any disposition available to the juvenile court.

(6) Make all reasonable prosecutorial efforts to reduce the time between arrest and disposition of the charge.

(7) Act as liaison with the court and other criminal justice agencies to establish local policies regarding the program and to ensure interagency cooperation in the planning and implementation of the program.

(8) Provide support and assistance to other agencies engaged in the program.

(c) Each participating probation department shall do all of the following:

(1) Cooperate in gathering data for use by all participating agencies pursuant to interagency agreement.

(2) Detain minors in custody who meet the detention criteria set forth in Section 628.

(4) Use all reasonable efforts to file violations of probation pursuant to Section 777 in a timely manner.

(5) Establish local policies in cooperation with law enforcement, the district attorney, schools, and the juvenile court regarding the program and provide support and assistance to other agencies engaged in the program.

(d) Each participating school district shall do all of the following:

(1) Cooperate in gathering data for use by all participating agencies pursuant to interagency agreement. School district access to records and data shall be limited to that information that is otherwise authorized by law.

(2) Report all crimes that are committed on campus by serious habitual offenders to law enforcement.

(3) Report all violations of probation committed on campus by serious habitual offenders to the probation officer or his or her designee.
