Over seventy years ago, United States Supreme Court Justice Robert H. Jackson accurately predicted the Supreme Court’s decision in Trump v. Hawaii. As he foresaw, the Court rubberstamped a President’s purposeful discrimination against a minority religion. This brief Essay explains Trump using Jackson’s critique of judicial review in national-security cases. The Essay also uses Trump to examine a flaw—probably structural—in the constitutional theory of process jurisprudence. The Trump case involved the Court’s construction of congressional legislation apparently limiting the President’s authority, but the present Essay does not address that aspect of the opinion.
