Article Four of the Constitution defines the complex, often contested relationship between states and federalism.
In short: Article Four of the U.S. Constitution governs the delicate balance between state autonomy and federal authority. From the mandate that states honor each other’s legal proceedings to the power of Congress to admit new states and manage vast federal lands, this foundational text shapes the American political landscape to this day.
Article Four establishes the framework for interstate relations and federal oversight. The Full Faith and Credit Clause requires states to recognize the public acts and judicial decisions of others, preventing the reopening of settled cases. However, this is not absolute; in McElmoyle v. Cohen (1839), the Supreme Court allowed Georgia to apply its own statute of limitations to a South Carolina judgment, confirming that procedural laws of the enforcing state still apply.
The Admissions Clause grants Congress the power to incorporate new states, expanding the Union from 13 to 50 members. While the Constitution does not explicitly require equal status for new states, the Supreme Court established the 'equal footing' doctrine in Lessee of Pollard v. Hagan (1845). This doctrine ensures that new states enter the Union with the same sovereignty as the original thirteen, though it has occasionally limited state control over resources, such as the coastal waters surrendered by Texas upon admission.
The Property Clause empowers Congress to manage federal lands, which currently account for about twenty-eight percent of U.S. territory. This authority is broad, allowing the federal government to regulate activities on public lands, such as the protection of wild horses and burros. Meanwhile, the Guarantee Clause mandates that every state maintain a 'republican form of government.' While the term remains undefined by the Constitution, it serves as a cornerstone for debates regarding the rights of citizens and the nature of American federalism.
Finally, the article addresses the movement of people and the stability of the Union. The Privileges and Immunities Clause prevents states from discriminating against citizens of other states, though courts have historically allowed some exceptions, such as residency-based access to natural resources. Furthermore, the Supreme Court ruled in Texas v. White (1869) that the Union is indissoluble, meaning states cannot unilaterally secede, cementing the finality of the relationship between the states and the federal government.
