There is a fundemental separation between the creation of law, and the execution of them. If the Executive is interpreting and executing a law in a way that Congress did not intend, Congress must have the power to investigate to determine how the law should be changed - otherwise the power to create law is meaningless.
Again, of course there is. You are pedantically focused on the âoverâ half of the word, and ignoring the âsightâ part.
Congress does not have the power to instruct the Executive on how to execute the law, outside of the text of the law itself - but they definitely do have the power to see how the law is executed.
This is an emotional argument. It does not matter what you imagine Congress âthinksâ - nor does it matter what you imagine I think. This is a very well-settled aspect of the separation of powers.
They are seeing to the administration of Congress itself.
It is interesting that your issue of contention is with legislative oversight of the executive, since in this instance, the executive is barely involved at all.
Fun fact: âseparate but equalâ doesnât appear in The Constitution. I thought such a strict textualist such as yourself might find that interesting.
Furthermore, since the American president is the most powerful man in the nation, if not the world, I should think youâd welcome oversight on such a powerful position.
But obviously, such power shouldnât be absolute. This is where your âedicts from ephorsâ come into play. They are the only tool we have to check such power. Vague theories an protestations on the internet certainly wonât cut it.
