The Supreme Court is one of the major flaws in the Constitution, as pointed out in an essay contemporaneous to the ratification conventions by Melancthon Smith republished in a collection called the Anti-Federalist Papers. Change a few words and you'd think you were listening to a current debate. Of course there is a provision in the Constitution allowing the Congress to remove anything from the appellate jurisdiction of the Court, most notably exercised in the wake of Ex Parte Milligan, which challenged the establishment of military tribunals when the civilain courts are still operating (why do you think the current military tribunals are in Guantanamo?). Congress avoided any further hostile or embarrassing rulings by legislating that the Court had no right to review its actions in these or other matters regarding Congressional Reconstruction. But ever since the federal judiciary learned their lesson from FDR and his attempts on the Court, they now realize who signs their paychecks and toe the line. I am of the impression that this practice of exclusion continues today mostly on pork barrel issues, by the slipping of amendments onto other bills.
