Which role ensures compliance with parliamentary procedure during meetings?

The role that ensures compliance with parliamentary procedure during meetings is the Parliamentarian. This individual is knowledgeable about the rules and procedures governing meetings, including the interpretation of the organization's bylaws and adherence to established parliamentary practices. The Parliamentarian assists the chair in maintaining order and ensures that discussions and decisions are conducted fairly and according to proper protocol. This role is critical in upholding the integrity of the meeting process, enabling members to participate appropriately while ensuring that the organization's governance framework is respected.

While the other roles like the Treasurer, Sergeant at Arms, and Recording Secretary have important functions—such as managing finances, maintaining order during meetings, and keeping accurate meeting records, respectively—they do not focus on parliamentary procedure. Thus, the Parliamentarian is the correct choice for ensuring that meetings run smoothly and in accordance with the established rules.
