Absolutely not. If Congress passes a law that says the President can only appoint Federal judges on the last Tuesday of March, July and November, is this constitutional?
And note that Pelosi and Schumer both voted for the Vacancies Act.
That's not a compelling argument. In fact, I'd say that's a pretty strong argument that the Vacancies Act is 100% unconstitutional. LOL.
if you the only tool is a hammer, everything looks like a nail.
Non sequitur argument. Prohibiting Constitutionally defined actions is fundamentally different than extending conditional permissions.
Most of what the Feds do is actually unconstitutional. This action isn’t any pattern for reversing that.
