Code of Civil Procedure section 1281.91 already establishes requirements concerning disqualification of arbitrators. This standard does not eliminate or otherwise limit those requirements or change existing authority or procedures for challenging an arbitrator's failure to disqualify himself or herself. The provisions of subdivisions (a)(1), (2), and (5) restate existing disqualification procedures under section 1281.91; (b) and (d) when an arbitrator makes, or fails to make, initial disclosures or where a section 170.1 ground exists. The provisions of subdivisions (a)(3) and (4) clarify the requirements relating to disqualification based on disclosure made by the arbitrator after appointment or based on the discovery by the party of a material omission or misrepresentation in the arbitrator's disclosure.
