What is the primary function of powers that govern territories or admit new states?

The primary function of powers that govern territories or admit new states falls under national powers. National powers are those granted to the federal government through the Constitution, and they include the authority to manage affairs related to the admission of new states as well as the governance of territories. This is outlined in the Constitution, specifically in Article IV, which provides the federal government with the responsibility to administer new states and territories, ensuring that they meet certain criteria before becoming part of the Union.

The other categories of powers include state powers, which are reserved for the states; concurrent powers, which are shared by both state and national governments; and reserved powers, which are those that are not delegated to the national government and are therefore retained by the states. However, the specific function of admitting new states is a distinctly national responsibility, distinguishing it from the other types of powers.
