What is the highest-ranking document that outlines the rules of an organization?

The highest-ranking document that outlines the rules of an organization is the Constitution/Bylaws. This document serves as the foundational governing framework for the organization, detailing its purpose, structure, and the rules by which it operates. It typically includes essential information such as membership qualifications, the roles and responsibilities of officers, meeting procedures, and amendment processes.

While a Corporate Charter is an important document that establishes the legal existence of an organization, it is not typically the primary resource for internal governance rules. Rules of Order refer to specific parliamentary procedures for conducting meetings but operate within the guidelines set forth by the Constitution/Bylaws. Standing Rules are more focused on the operational aspects of meetings or specific procedures and are subordinate to the Constitution/Bylaws.

Thus, the Constitution/Bylaws hold the highest authority and provide the overarching rules and principles that guide the organization, making it the correct answer.
