CA Penal Code Section 1001.96

(a)

If the defendant, during the period of deferral imposed pursuant to subdivision (a) of Section 1001.94, complies with all terms, conditions, and programs required by the court, then, the judge shall, at the end of the period, strike the defendant’s plea and dismiss the action against the defendant.

(b)

Upon successful completion of the terms, conditions, or programs ordered by the court, the arrest upon which sentencing was deferred shall be deemed to have never occurred. The defendant may indicate in response to any question concerning his or her prior criminal record that he or she was not arrested or granted deferred entry of judgment for the offense, except as specified in subdivision (c). A record pertaining to an arrest resulting in successful completion of the terms, conditions, or programs ordered by the court shall not, without the defendant’s consent, be used in any way that could result in the denial of any employment, benefit, license, or certificate.

(c)

The defendant shall be advised that, regardless of his or her successful completion of the terms, conditions, or programs ordered by the court pursuant to this chapter, the arrest upon which the judgment was deferred may be disclosed by the Department of Justice in response to a peace officer application request and that, notwithstanding Section 1001.94, this section does not relieve him or her of the obligation to disclose the arrest in response to a direct question contained in a questionnaire or application for a position as a peace officer, as defined in Section 830.
