It is expected that anyone invited to participate in any aspect of reviewing, mediating, investigating or adjudicating an ethics complaint will decline if they have a conflict of interest or personal or professional relationship with a party or entity that would lead to bias or the perception thereof. A member may challenge the appointment of any person to any of these positions if that member can demonstrate reasonable cause for the member to believe there is conflict of interest or bias. A member does not have unlimited challenges to appointments and the judgment as to whether or not a conflict or bias exists will remain with the people designated to make the appointments.
