Cal. Gov't Code § 71654
Subject to meet and confer in good faith, each trial court shall establish in its personnel rules a process for the trial court to review a hearing officer’s report and recommendation made pursuant to Section 71653 that provides, at a minimum, that the decision of the hearing officer shall be subject to review, as follows:
(c) If the trial court rejects or modifies the hearing officer’s recommendation, the trial court shall specify the reason or reasons why the recommended disposition is rejected in a written statement which shall have direct reference to the facts found and shall specify whether the material factual findings are supported by substantial evidence. The trial court may reject or modify the recommendation of the hearing officer only if the material factual findings are not supported by substantial evidence, or for any of the following reasons or reasons of substantially similar gravity or significance:
(d) If a trial court’s review results in rejection or substantial modification of the hearing officer’s recommendation, then the final review shall be conducted by an individual other than the disciplining officer. If the disciplining officer is a judge of the trial court, the review shall be made by another judge of the court, a judicial committee, an individual, or panel as specified in the trial court’s personnel rules. However, in a trial court with two or fewer judges, if the trial court has no other judge than the disciplining judge or judges, the judge or judges may conduct the review; and, as a minimum requirement, in a trial court with 10 or more judges, the review shall be by a panel of three judges, whose decision shall be by a majority vote, which shall be selected as follows:
(3) The two appointed judges shall select a third judge.
On panels in a trial court with 10 or more judges, no judge may be selected to serve without his or her consent; the term of office of the panel shall be defined by local personnel policies, procedures, or plans subject to the obligation to meet and confer in good faith; and no judge shall serve on the panel in a case in which he or she has imposed discipline.
