Who has the authority to change the boundaries of the state of Arizona?

The authority to change the boundaries of the state of Arizona lies with the legislature of Arizona, in conjunction with the adjacent states, and requires the approval of the U.S. Congress. This process is grounded in legal and constitutional principles that govern the admission of states and any alterations to their borders.

When states were first created, the U.S. Constitution provided a framework for how changes to state boundaries could occur. While state legislatures can propose boundary changes, any alteration must be agreed upon by the neighboring states that could be affected by such changes. Ultimately, the U.S. Congress must approve these proposals to ensure they align with federal laws and do not disrupt the balance of power among states. This federal oversight protects the integrity of state borders and maintains national interests.

The other options do not correctly address the legal framework governing state boundary changes. The President does not have the authority to unilaterally change state boundaries as that would violate the principles of state sovereignty and the Constitution. Although residents can express their preferences through votes on related state matters, they do not directly change state boundaries without the legislative and congressional process. Similarly, the Supreme Court of Arizona handles legal disputes and interpretations of law, but it does not have the authority to alter state borders. Thus
