Which significant document outlines the foundational legal structure of the state of Arizona?

The Arizona Constitution is the foundational legal document that establishes the structure of government for the state of Arizona. It provides the framework for state governance, including the separation of powers among the legislative, executive, and judicial branches. The Constitution also delineates the rights and responsibilities of state officials and the rights of citizens within Arizona.

In contrast, while the Arizona Bill of Rights does protect individual rights, it is actually a part of the Arizona Constitution, making it less comprehensive than the Constitution as a whole. The Declaration of Independence is a historic document that announced the colonies' separation from British rule but does not serve as a legal framework for governance in Arizona or any state. The Federalist Papers are a series of essays promoting the ratification of the U.S. Constitution and do not pertain specifically to Arizona's legal structure. Thus, the Arizona Constitution stands as the primary source of state law and governance.
