Which article of the U.S. Constitution states that treaty obligations are the supreme law of the land?

The statement that treaty obligations are the supreme law of the land is found in Article 6 of the U.S. Constitution. This article is significant because it establishes the supremacy of the Constitution and federal laws made in accordance with it, as well as treaties made under the authority of the United States. This means that treaties, once ratified, take precedence over state laws and can be enforced in the courts. By designating treaties as part of the supreme law, it underscores the importance of international agreements in governance and ensures that the United States upholds its commitments on the global stage. Understanding this provision is critical for grasping the legal framework within which the U.S. operates, especially in matters that involve foreign relations and international law.
