The critical paragraph in the above-cited article writes:
"Trump's executive order cites the president's authority under the Immigration and Nationality Act of 1952, specifically this provision:Our analysis of this matter is as follows:
"Whenever the President finds that the entry of any aliens or of any class of aliens into the United States would be detrimental to the interests of the United States, he may by proclamation, and for such period as he shall deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or nonimmigrants, or impose on the entry of aliens any restrictions he may deem to be appropriate."" [emphasis added]
The holdings of a federal judge as also the 9th Circuit Court of Appeals (which has an 80% reversal record before the United States Supreme Court) are clearly in error because they are not applying the above law neutrally but rather are "second-guessing" the wisdom of and reasons for the President's order -- a proclamation which is in his power to make based on the above law.
Whether such an order was wisely drafted or not is not within the power of the courts to review, because such an order is the President's responsibility. Indeed, his decision can be based upon confidential information to which only he has access and which he can not or should not make public.
It can not be as a matter of Constitutional Law that local or appellate judges can play U.S. President by second-guessing the reasons for which a President exercises his lawful powers, as granted by the Constitution and the Congress.
The only legal question here is whether the President has the power to issue the order that he has issued, and that is eminently clear based on the Immigration and Nationality Act of 1952. He has that power.
That some judge or judges on some court of the land would handle the matter differently is equally clear, but they are not the President, and they are usurping powers in this matter that they do not have, and so the U.S. Supreme Court should decide, once the matter gets to that level of jurisprudence.
Imagine what chaos would ensue if any and all Presidential powers could be limited nationally by some local judge out there who thought differently about the President's actions and orders.
Presidential orders are not at the mercy of local judges. This is because law at this level of the separation of powers can not not be a chaotic button-button, who's got the button process, whereby some judge in the nation substitutes his opinion for that of the President of the United States.
Again, whether the immigration order is a wise one or not is a different question, and one that must be solved within the political process. The legal question, however, is the power of the President. And that power is clear.
