Haw. Code R. § 11-201-7
Any party to a hearing, up to five days before the proceeding, may file an affidavit that one or more of the council members or a hearing officer has a personal bias or prejudice. The council member against whom the affidavit is so filed may answer the affidavit or may file a disqualifying certificate with the council. If the council member or hearing officer chooses to answer the affidavit, the remaining council members shall decide by a majority of all the members to which the council is entitled whether that council member or hearing officer shall be disqualified from the proceeding. Every affidavit shall state the facts and reasons for the belief that bias or prejudice exists and shall be filed at least five days before the hearing, or good cause shall be shown for the failure to file it within the time. Any council member or hearing officer may request disqualification by filing with the chairperson a certificate that deems that person unable for any reason to preside with impartiality in the pending hearing.
