Haw. Rev. Stat. § 76-51

No person who occupies any elective or appointive office under the state or county government shall be eligible for membership on or continue to be a member of the merit appeals board. The term "appointive office" for the purpose of this section, shall not include notaries public. No member of the merit appeals board shall, during the member's term of office, serve as an officer or committee member of any political party organization, including a precinct organization, or present oneself as a candidate or be a candidate for nomination or election to any public office at any election. The office of any member who violates this section or section 84-13 or 84-14 shall be conclusively presumed to have been abandoned and vacated by reason thereof and the chief executive shall thereupon appoint a qualified person to fill the vacancy. As an alternative remedy, proceedings in the nature of quo warranto may be brought by any person to oust any member who violates this section or section 84-13 or 84-14.
