The Parliamentarian is a consultant, commonly a professional, who advises the president and other officers, committees, and members on matters of parliamentary procedure. The parliamentarian's role during a meeting is purely an advisory and consultative one--since parliamentary law gives to the chair alone the power to rule on questions of order or to answer parliamentary inquiries.
