What document defines the relationships between the government and its citizens?

The Constitution is the foundational legal document that outlines the structure of government and establishes the relationships and rights between the government and its citizens. It serves as the supreme law of the land, providing guidelines for the operation of government and ensuring individual liberties through various amendments, including the Bill of Rights.

The Bill of Rights specifically enumerates individual freedoms and protections, but it functions as an amendment to the Constitution rather than a standalone document that defines the relationship between the government and its citizens. A charter typically refers to a document that creates a municipality or organization, and while it may include some regulations important to a local jurisdiction, it does not encompass the broader relationship between a government and its citizens on a national level. An ordinance is a regulation or law enacted by a local government but does not have the comprehensive scope or authoritative standing in defining government-citizen relationships as the Constitution does.
