California Code, Penal Code - PEN § 1000.2

(a) The court shall hold a hearing and, after consideration of any information relevant to its decision, shall determine if the defendant consents to further proceedings under this chapter and if the defendant should be granted pretrial diversion. If the defendant does not consent to participate in pretrial diversion, the proceedings shall continue as in any other case.

(b) At the time that pretrial diversion is granted, any bail bond or undertaking, or deposit in lieu thereof, on file by or on behalf of the defendant shall be exonerated, and the court shall enter an order so directing.

(c) The period during which pretrial diversion is granted shall be for no less than 12 months nor longer than 18 months. However, the defendant may request, and the court shall grant, for good cause shown, an extension of time to complete a program specified in subdivision (c) of Section 1000. Progress reports shall be filed by the probation department with the court as directed by the court.
