CAL. PEN. CODE § 679.04 : California Code - Section 679.04

(a) A victim of sexual assault as the result of any offense specified in paragraph (1) of subdivision (b) of Section 264.2 has the right to have victim advocates and a support person of the victim' s choosing present at any interview by law enforcement authorities, district attorneys, or defense attorneys. However, the support person may be excluded from an interview by law enforcement or the district attorney if the law enforcement authority or the district attorney determines that the presence of that individual would be detrimental to the purpose of the interview. As used in this section, "victim advocate" means a sexual assault counselor, as defined in Section 1035.2 of the Evidence Code, or a victim advocate working in a center established under Article 2 (commencing with Section 13835) of Chapter 4 of Title 6 of Part 4.

This subdivision applies to investigators and agents employed or retained by law enforcement or the district attorney.

(2) At the time the victim is advised of his or her rights pursuant to paragraph (1), the attending law enforcement authority or district attorney shall also advise the victim of the right to have victim advocates and a support person present at any interview by the defense attorney or investigators or agents employed by the defense attorney.

(c) An initial investigation by law enforcement to determine whether a crime has been committed and the identity of the suspects shall not constitute a law enforcement interview for purposes of this section.
