California Code, Business and Professions Code - BPC § 467.7

(a) Unless the parties have agreed to a binding award, nothing in this chapter shall be construed to prohibit any person who voluntarily enters the dispute resolution process from revoking his or her consent, withdrawing from dispute resolution, and seeking judicial or administrative redress.

(b) In cases in which a criminal complaint has been filed by a prosecutor, other than for an infraction, the advice of counsel shall be obtained before any dispute resolution process is initiated.  Nothing in this subdivision shall be construed to preclude a defendant from knowingly and voluntarily waiving the right to counsel.  A defendant who indicates a desire to waive the right to counsel shall be encouraged to consult with the public defender or private counsel before waiving that right.
