The last I recall reading was that 7 of 9 judges agreed that in certain circumstances 'international law' should be considered.
We're too close to losing America for my comfort. Having a law which orders the legislators and the Courts to follow the Constitution is the best answer I can think of.
It will protect the Bill of Rights and everything else.
Not when one of its essential clauses opens us up for direct violations of the first amendment.
Why are we losing America?
This legislation does nothing to fight the root causes of our trouble. But it does give some nasty people a few clauses they might be able to use to bring a different sort of tyranny upon us in the name of cultural security and safety. Remember what Benjamin Franklin said about them!
