While these treaties are atrocious, and any one of them would be problematic if ratified, the United States Supreme Court absolutely CAN overturn all or part of any treaty which it decides violates the United States Constitution.
Article III, Section 2: "The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority..."
Yes, and it also says:
This Constitution, and the Laws of the United States which shall be made in Pursuance therefore; 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.
That last clause leaves me a bit uncertain.
That’s reassuring. I already can’t trust 67 Senators to do the right thing; you think I can trust 9 black robes?
