[cr #2644 desperately changing what he said] None of those are legislative acts, similar to creating a state.
[cr #2644] You seriously need to work on context. Try again.
What you said was, "What Congress can do, Congress can undo." You seriously need to work on context.
What Article 4, Section 3, Clause 1 says is "New States may be admitted by the Congress into the Union...."
It does not say Congress may create a state. You seriously need to work on context.
While you are seriously working on cleaning up your misbegotten context, you may make a desperate search for any legal authority who so much as mentions your cockamamie theory of Constitutional law.
"New States may be admitted by the Congress into this Union; but no new State shall be formed or erected within the Jurisdiction of any other State; nor any State be formed by the Junction of two or more States, or Parts of States, without the Consent of the Legislatures of the States concerned as well as of the Congress."
"It is an "express" power of Congress to create (evolve) new states. When new states are organized from within the boundaries of a state, or multiple states, then those states must also agree."
"Likewise, it is implied that what Congress can do, Congress can undo. Suppose that the states North and South Dakota, formed from the former Dakota Territory, desired to combine and and form "Greater Dakota." With the consent of the two states and by an act of Congress the new state of "Greater Dakota" would be created, and the former entities of North and South Dakota would be devolved."
So we see the context was concerning the creation of states by the Congress, because they do not exist as an state prior to that time. There was no mention of "adjournment" - a stupid retort. There was no mention of anything like impeachment, a process where the House prosecutes and the Senates sits in judgment - another stupid retort. There is no mention of anything like advice and consent - yet another stupid retort. The context is clear. It is about organizing and forming new states. And how does Congress do that? Through the legislative process.
"While you are seriously working on cleaning up your misbegotten context, you may make a desperate search for any legal authority who so much as mentions your cockamamie theory of Constitutional law."
The only question now is, "Is nolu chan ignorant or just a jerk?" The correct answer is ... both.
