The Ninth Circuit ignores precedent and threatens national security

Further, as the Supreme Court explained in Knauff v. Shaughnessy (1950), the authority to exclude aliens “stems not alone from the legislative power but is inherent in the executive power to control the foreign affairs of the nation.” In issuing the order, the president was acting at the apex of his authority. As Justice Robert Jackson noted in Youngstown v. Sawyer (1952): “When the President acts pursuant to an express or implied authorization of Congress, his authority is at its maximum, for it includes all that he possesses in his own right plus all that Congress can delegate.” That point the Ninth Circuit ignored entirely.

The order, frequently mischaracterized as a “Muslim ban,” is actually directed at seven countries that the president believes present a particular threat to U.S. security—a view with which Congress agreed in 2015. All are beset by terrorists and so uncertain and chaotic that proper vetting of potential refugees and immigrants is virtually impossible.

President Obama chose to toughen vetting standards for these countries’ nationals rather than bar their entry completely. But if Mr. Trump has a different view of the threat, it is not up to the courts to decide who is right. This is a classic example of a nonjusticiable “political question,” involving matters constitutionally vested in the president and Congress.
