Final answer:
The documents that detail local chapter organization and policies are bylaws, which must align with the overarching Constitution and Statutes but can be more restrictive.
Step-by-step explanation:
The documents that detail local chapter organization and policies are known as bylaws. These bylaws can be more restrictive but cannot be less restrictive than the overarching Constitution and Statutes of an organization. Essentially, while the Constitution sets the fundamental principles and overarching guidelines for an organization's operation, bylaws are the rules by which the local chapter of that organization governs itself. Charters, similar to state constitutions, provide a framework and detail the specific responsibilities and authority areas of local government bodies, just as bylaws do for chapters within an organization.
