Oops, see post 287 responding to 268. I don’t know what others have said in this thread regarding the duties of Congress and President to the Constitution, but they do have the duty, the right and the power to interpret the Constitution and apply it. We’ve hurt our nation by allowing the President and Congress to ignore that duty. The Congress will actually, knowingly, pass Constitutionally suspect legislation with some Congressmen saying that the courts will strike it down IF they find it unconstitutional. That is very bad. It removes a bulwark against loss of our rights under our Constitution.
Yes, the President and Congress have a duty follow the Constitution in everything they do. I also agree with you that Congressmen passing suspect legislation in the anticipation that the court will strike it down is also disgraceful.
But that does not mean they can simply ignore a SCOTUS decision. You have provided zero support for that assertion thus far.
