Theres an interesting fight brewing down in Alabama that will press the envelope on our understanding of federalism. What do you do when a federal court orders a state court judge to remove the 10 Commandments from a broader display of the origins of law in western civilization? The federal order is clearly contrary to the original understanding of the Establishment Clause, and a lower federal court clearly has no hierarchical power over a state court (only the Supreme Court has that). But can the state court judge just ignore the order without bringing about a nullification crisis of Calhounian proportions? Alabama Attorney General William Pryor, no opponent of 10 Commandments displays, thinks not. Methinks we havent heard the last of this showdown.
