In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make. This means that the Supreme Court ultimately gets to determine what is kosher or not, in respect of treaty obligations. (What you quoted mainly speaks to federal authority versus state authority). Among the things the Court has determined: Congressional Repeal of Treaties .--It is in respect to his contention that, when it is asked to carry a treaty into effect, Congress has the constitutional right, and indeed the duty, to determine the matter according to its own ideas of what is expedient, that Madison has been most completely vindicated by developments. This is seen in the answer which the Court has returned to the question: What happens when a treaty provision and an act of Congress conflict? The answer is, that neither has any intrinsic superiority over the other and that therefore the one of later date will prevail leges posteriores priores contrarias abrogant. In short, the treaty commitments of the United States do not diminish Congress' constitutional powers. To be sure, legislative repeal of a treaty as law of the land may amount to a violation of it as an international contract in the judgment of the other party to it. In such case, as the Court has said: ''Its infraction becomes the subject of international negotiations and reclamations, so far as the injured party chooses to seek redress, which may in the end be enforced by actual war. It is obvious that with all this the judicial courts have nothing to do and can give no redress.'' 303 caselaw.lp.findlaw.com The foregoing means that a treaty provision can be superceded by an simple act of Congress.
