Full Text of Rule 3.904

Text sizeJump to: (a) (b)

(a) Certification by referee Before a referee begins to serve:
(1) The referee must certify in writing that he or she consents to serve as provided in the order of appointment and is aware of and will comply with applicable provisions of canon 6 of the Code of Judicial Ethics and with the California Rules of Court; and
(2) The referee’s certification must be filed with the court.
(b) Disclosure by referee In addition to any other disclosure required by law, no later than five days before the deadline for parties to file a motion for disqualification of the referee under Code of Civil Procedure section 170.6 or, if the referee is not aware of his or her appointment or of a matter subject to disclosure at that time, as soon as practicable thereafter, a referee must disclose to the parties:
(1) Any matter subject to disclosure under either canon 6D(5)(a) or 6D(5)(b) of the Code of Judicial Ethics; and
(2) Any significant personal or professional relationship the referee has or has had with a party, attorney, or law firm in the current case, including the number and nature of any other proceedings in the past 24 months in which the referee has been privately compensated by a party, attorney, law firm, or insurance company in the current case for any services. The disclosure must include privately compensated service as an attorney, expert witness, or consultant or as a judge, referee, arbitrator, mediator, settlement facilitator, or other alternative dispute resolution neutral.

Plain-English Summary

Before a stipulated referee does anything on the case, Rule 3.904 requires two separate steps. First comes certification: the referee must state in writing that they consent to serve on the terms the appointment order sets, and that they are aware of and will comply with canon 6 of the Code of Judicial Ethics and with the California Rules of Court. That certification gets filed with the court, creating a record that the referee accepted the same ethical constraints that bind a sitting judge before ever holding a hearing.

Second comes disclosure, and the timing matters. No later than five days before the deadline for a party to move to disqualify the referee under Code of Civil Procedure section 170.6, or as soon as practical afterward if the referee did not yet know of the appointment or the disclosable matter, the referee has to tell the parties about anything covered by the judicial-ethics disclosure canons, plus any significant personal or professional relationship with a party, attorney, or law firm in the case. That second category reaches back 24 months and covers paid work of almost any kind, as an attorney, expert witness, or consultant, or as a judge, referee, arbitrator, mediator, settlement facilitator, or other alternative dispute resolution neutral. The point is to put real information about conflicts in front of the parties while they still have time to act on it.
