You asked whether an ex-officio member can vote at a meeting of a committee that operates under Robert's Rules of Order.

The Office of Legislative Research is not authorized to issue a legal opinion and this memorandum should not be considered as one.

Under Robert's Rules, an ex-officio member is a full-fledged member of the body with all the accompanying rights. An ex-officio member has the same rights as the other committee members, but is not obligated to attend meetings of the committee and is not counted in determining if a quorum is present (§§ 46, 48, and 49, 9^th edition, 1990). Unless a charter or the committee's by-laws prohibit it, an ex-officio committee member is entitled to vote.
