58. Not "possible", not "could be" - the UN Charter doesn't apply as you are describing

Its been pretty well conspiracy-theoried to death, so there is no shortage of speculation and argument online, but what it comes down to (here as well as regarding the OP) is settled law, as decided by the Supreme Court interpreting the US Constitution.

Nothing in the US charter, even considered as a treaty we are signatory on, has legal standing or establishes law here, unless a specific federal implementing law is written, passed and signed for each case. Which puts the UN in the same boat as anyone else - if you have a law you want implemented, you have to get a majority in our elected congress to support it, then you have to have the president sign it.

"Could be considered binding legislation here" was, perhaps, at one time valid speculation, but the Supreme Court decided very broadly against that possibility in Medellin vs. Texas. They left little room for ifs and maybes in that decision, and its unlikely to come up again.
