CJ Roy Moore on the possibility of defying a SCOTUS ruling:
(From an AL radio program, quoted in the NYT)
Also from that NYT article (although the whole thing's worth a read):
Chief Justice Marshall observed, “If the legislatures of the several states may at will annul the judgments of the courts of the United States, and destroy the rights acquired under those judgments, the Constitution itself becomes a solemn mockery.” This holds just as true if state courts exercise an identical nullification power over federal court orders.
The Alabama Supreme Court’s action represents an unfortunate departure from the cooperative norm that must prevail between these independent judicial systems. Other state judiciaries would do well not to follow its example.
