Full Text of Rule 3.869
Plain-English Summary
Rule 3.869 is the backbone of the complaint article — it lists the minimum steps every court’s local complaint procedure has to include, from intake through final decision. Complaints start with the complaint coordinator, who logs the inquiry, sends the complainant written acknowledgment, and conducts a preliminary review to see whether the matter can be resolved informally or closed without further process. Most complaints end there.
If a complaint survives that first look, the rule adds more structure. The mediator has to be told about the complaint and given a chance to respond. Someone with mediation experience — either an individual or a committee that includes one — has to investigate and recommend an outcome; only a small court of eight or fewer authorized judges can skip that experience requirement, and only if it cannot find a qualified person or faces some other hardship. Whatever the recommendation, the final call belongs to the presiding judge or a designee, and that person cannot be the same one who coordinated intake or ran the investigation.
The rule closes with housekeeping duties: notify the complainant of the outcome in every case, notify the mediator too if the complaint made it past the preliminary stage, handle every complaint promptly, and keep enough records to spot patterns across complaints over time.
Advisory Committee Comment
The following comment is published by the Judicial Council of California alongside the rule itself — not commentary from this site.
Judicial Council staff have developed model local rules that satisfy the requirements of this rule. These model local rules were developed with input from judicial officers, court administrators, alternative dispute resolution (ADR) program administrators, court-program mediators, and public commentators and are designed so that they can be readily adapted to the circumstances of individual courts and specific complaints. Courts are encouraged to adopt rules that follow the model rules, to the extent feasible. Courts can obtain copies of these model rules from the Judicial Council’s civil ADR program staff. Subdivision (a). Coordination of inquiries and complaints by a person knowledgeable about mediation is important to help ensure that the requirements of this article are followed and that mediation confidentiality is preserved. Subdivision (c). Courts are encouraged to resolve inquiries and complaints about mediators using the simplest, least formal procedures that are appropriate under the circumstances, provided that they meet the requirements stated in this article. Most complaints can be appropriately resolved during the preliminary review stage of the complaint process, through informal discussions between or among the complaint coordinator, the complainant, and the mediator. Although complaint coordinators are not required to communicate with the mediator during the preliminary review, they are encouraged to consider doing so. For example, some complaints may arise from a misunderstanding of the mediator’s role or from behavior that would not violate the standards of conduct. These types of complaints might appropriately be addressed by providing the complainant with additional information or by informing the mediator that certain behavior was upsetting to a mediation participant. The circumstances under which a complaint coordinator might informally resolve or close a complaint include, for example, when (1) the complaint is withdrawn; (2) no violation of the rules of conduct appears to have occurred; (3) the alleged violation of the rules of conduct is very minor and the mediator has provided an acceptable explanation or response; and (4) the complainant, the mediator, and the complaint coordinator have agreed on a resolution. In determining whether to close a complaint, the complaint coordinator might also consider whether there are or have been other complaints about the mediator. Subdivision (d). At the investigation and recommendation stage, all courts are encouraged to consider using a complaint committee comprised of members with a variety of backgrounds, including at least one person with experience as a mediator, to investigate and make recommendations concerning those rare complaints that are not resolved during the preliminary review. Courts are also encouraged to have a judicial officer who is knowledgeable about mediation, or a committee that includes another person who is knowledgeable about mediation, make the final decision on complaints that are not resolved through the preliminary review.
Frequently Asked Questions
Who is the complaint coordinator?
Rule 3.869 does not name a particular position — it is whoever the court designates to receive complaints, acknowledge them in writing, and conduct the preliminary review.
What happens if a complaint is not resolved during the preliminary review?
The mediator gets notice and a chance to respond, a person with mediation experience (or a committee including one) investigates and recommends an outcome, and the presiding judge or a designee makes the final decision.
Can a small court skip the requirement for an experienced mediator to investigate?
Only a court with eight or fewer authorized judges may waive that requirement, and only if it cannot find a qualified person or shows other hardship.
Who makes the final decision on a mediator complaint?
The presiding judge or a designee, and that person cannot be the complaint coordinator or whoever investigated the complaint.
