Which document outlines the specific rules and procedures that govern an assembly's meetings?

The document that outlines the specific rules and procedures governing an assembly's meetings is known as the Standing Rules. Standing Rules are typically established by an organization to provide detailed guidance on the conduct of meetings, including how members can speak, how votes are conducted, and any other operational procedures necessary for the smooth functioning of the assembly. These rules are designed to be flexible and can be amended as needed to adapt to the organization’s requirements.

While the Constitution of an organization sets forth its fundamental principles and structure, and the Rules of Order provide a broad framework for parliamentary procedure, the Standing Rules focus on the specific applications and adaptations of those procedures within the context of that assembly. A Corporate Charter primarily deals with the organization's formation and governance in a legal context rather than the detailed meeting procedures, making the Standing Rules the most relevant document for regulating the day-to-day operations of meetings.
