Article VI. - Debts, Supremacy, Oaths All Debts contracted and Engagements entered into, before the Adoption of this Constitution, shall be as valid against the United States under this Constitution, as under the Confederation.

This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.

The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.

L’article 6 de la Constitution des Etats-Unis érige les Traités internationaux auxquels ils sont partie au niveau de norme suprême de droit sur le territoire américain au même titre que la Constitution. Aucune constitution ou loi d’un Etat ne peut y être contraire. C’est la seule disposition de la Constitution Américaine concernant le droit international et elle peut à ce titre être comparée au Titre VI de la Constitution Française de 1958 et notamment à l’article 55.
