(a) If the prosecuting attorney determines that this chapter may be applicable to the defendant, he or she shall advise the defendant and his or her attorney in writing of that determination. This notification shall include all of the following: (1) A full description of the procedures for deferred entry of judgment. (2) A general explanation of the roles and authorities of the probation department, the prosecuting attorney, the program, and the court in the process. (3) A clear statement that in lieu of trial, the court may grant deferred entry of judgment with respect to any crime specified in subdivision (a) of Section 1000 that is charged, provided that the defendant pleads guilty to each of these charges and waives time for the pronouncement of judgment, and that upon the defendant’s successful completion of a program, as specified in subdivision (c) of Section 1000, the positive recommendation of the program authority and the motion of the prosecuting attorney, the court, or the probation department, but no sooner than 18 months and no later than three years from the date of the defendant’s referral to the program, the court shall dismiss the charge or charges against the defendant. (4) A clear statement that upon any failure of treatment or condition under the program, or any circumstance specified in Section 1000.3, the prosecuting attorney or the probation department or the court on its own may make a motion to the court for entry of judgment and the court shall render a finding of guilt to the charge or charges pled, enter judgment, and schedule a sentencing hearing as otherwise provided in this code. (5) An explanation of criminal record retention and disposition resulting from participation in the deferred entry of judgment program and the defendant’s rights relative to answering questions about his or her arrest and deferred entry of judgment following successful completion of the program.

(b) If the defendant consents and waives his or her right to a speedy trial or a speedy preliminary hearing, the court may refer the case to the probation department or the court may summarily grant deferred entry of judgment if the defendant pleads guilty to the charge or charges and waives time for the pronouncement of judgment. When directed by the court, the probation department shall make an investigation and take into consideration the defendant’s age, employment and service records, educational background, community and family ties, prior controlled substance use, treatment history, if any, demonstrable motivation, and other mitigating factors in determining whether the defendant is a person who would be benefited by education, treatment, or rehabilitation. The probation department shall also determine which programs the defendant would benefit from and which programs would accept the defendant. The probation department shall report its findings and recommendations to the court. The court shall make the final determination regarding education, treatment, or rehabilitation for the defendant. If the court determines that it is appropriate, the court shall grant deferred entry of judgment if the defendant pleads guilty to the charge or charges and waives time for the pronouncement of judgment.

(c) No statement, or any information procured therefrom, made by the defendant to any probation officer or drug treatment worker, that is made during the course of any investigation conducted by the probation department or treatment program pursuant to subdivision (b), and prior to the reporting of the probation department’s findings and recommendations to the court, shall be admissible in any action or proceeding brought subsequent to the investigation.

No statement, or any information procured therefrom, with respect to the specific offense with which the defendant is charged, that is made to any probation officer or drug program worker subsequent to the granting of deferred entry of judgment, shall be admissible in any action or proceeding, including a sentencing hearing.

(d) A defendant’s plea of guilty pursuant to this chapter shall not constitute a conviction for any purpose unless a judgment of guilty is entered pursuant to Section 1000.3.
