The Legislatures of the aggrieved States were soon in full hue and cry at the heels of the Court; and from them the agitation quickly spread to Congress. ¹ On December 12, 1821, Senator Johnson of Kentucky proposed an amendment to the Constitution which was intended to substitute the Senate for the Supreme Court in all constitutional cases. In his elaborate speech in support of his proposition, Johnson criticized at length the various decisions of the Court but especially those grounded on its interpretation of the "obligation of contracts" clause. More than that, however, he denied in toto the rights of the Federal Courts to pass upon the constitutionality either of acts of Congress or of state legislative measures. So long as judges were confined to the field of jurisprudence, the principles of which were established and immutable, judicial independence was all very well, said Johnson, but "the science of politics was still in its infancy"; and in a republican system of government its development should be entrusted to those organs which were responsible to the people. Judges were of no better clay than other folk. "Why, then," he asked, "should they be considered any more infallible, or their decisions any less subject to investigation and revision?" Furthermore, "courts, like cities, and villages, or like legislative bodies, will sometimes have their leaders; and it may happen that a single individual will be the prime cause of a decision to overturn the deliberate act of a whole State or of the United States; yet we are admonished to receive their opinions as the ancients did the responses of the Delphic oracle, or the Jews, with more propriety, the communications from Heaven delivered by Urim and Thummim to the High Priest of God's chosen people." ¹ For a good review of the contemporary agitation aroused by Marshall's decisions, see two articles by Charles Warren in the American Law Review, vol. XLVII, pp. 1 and 161.
