deemed certain, and founded in permanent principles, and not dependent upon the caprice, or will of particular judges. A more alarming doctrine could not be promulgated by any American court, than that it was at liberty to disregard all former rules and decisions, and to decide for itself, without reference to the settled course of antecedent principles.
§ 378. This known course of proceeding, this settled habit of thinking, this conclusive effect of judicial adjudications, was in the full view of the framers of the constitution. It was required, and enforced in every state in the Union; and a departure from it would have been justly deemed an approach to tyranny and arbitrary power, to the exercise of mere discretion, and to the abandonment of all the just checks upon judicial authority. It would seem impossible, then, to presume, if the people intended to introduce a new rule in respect to the decisions of the Supreme Court, and to limit the nature and operations of their judgments in a manner wholly unknown to the common law, and to our existing jurisprudence, that some indication of that intention should not be apparent on the face of the constitution. We find, (Art. 4,) that the constitution has declared, that full faith and credit shall be given in each state to the judicial proceedings of every other state. But no like provision has been made in respect to the judgments of the courts of the United States, because they were plainly supposed to be of paramount and absolute obligation throughout all the states. If the judgments of the Supreme Court upon constitutional questions are conclusive and binding upon the citizens at large, must they not be equally conclusive upon the states? If the states are parties to that instrument, are not the people of the states also parties?
