How does the Constitution describe the relationship between states?

The Constitution establishes a framework for cooperation and interaction among the states, emphasizing that states must recognize the acts, records, and judicial proceedings of other states. This principle is primarily rooted in the Full Faith and Credit Clause found in Article IV, Section 1 of the Constitution. This clause mandates that states honor the public acts, records, and judicial decisions of other states, which fosters legal uniformity and stability across the nation.

This foundational aspect of constitutional law is crucial in maintaining a cohesive federal system, ensuring that legal matters such as marriage licenses, judicial rulings, and other state-recognized foils are acknowledged across state lines. By upholding this principle, the Constitution reinforces mutual respect and legal recognition among states, promoting a unified legal framework under which citizens operate across different jurisdictions.
