An arbitrator must act in a manner that upholds the integrity and fairness of the arbitration process. He or she must maintain impartiality toward all participants in the arbitration at all times.
Cal. R. Ct. Standard 5
Comment to Standard 5
This standard establishes the overarching ethical duty of arbitrators. The remaining standards should be construed as establishing specific requirements that implement this overarching duty in particular situations.
Maintaining impartiality toward all participants during all stages of the arbitration is central to upholding the integrity and fairness of the arbitration. An arbitrator must perform his or her duties impartially, without bias or prejudice, and must not, in performing these duties, by words or conduct manifest partiality, bias, or prejudice, including but not limited to partiality, bias, or prejudice based upon race, sex, religion, national origin, disability, age, sexual orientation, socioeconomic status, or the fact that a party might select the arbitrator to serve as an arbitrator in additional cases. After accepting appointment, an arbitrator should avoid entering into any relationship or acquiring any interest that might reasonably create the appearance of partiality, bias, or prejudice. An arbitrator does not become partial, biased, or prejudiced simply by having acquired knowledge of the parties, the issues or arguments, or the applicable law.
