"This power [the Supreme Court] has the last word in the numberless questions which come under its jurisdiction. The sovereign people after a time conquers the other powers, but this Supreme Court almost always remains beyond its reach. For more than twenty or even thirty years, twice the _grande mortalis aevi spatium_, it may misuse its authority with impunity, may practically invalidate a law voted by all the other powers, or a policy unanimously accepted by public opinion. It may nullify a regular diplomatic treaty[87] ... by refusing to enforce it by judicial sanction, or may lay hands on matters belonging to the sovereignty of the states and federalize them without one's being able to make any effective opposition, for this Court itself determines its own jurisdiction as against the state tribunals. It is one of Blackstone's maxims that in every constitution a power exists which controls without being controlled, and whose decisions are supreme. This power is represented in the United States by a small oligarchy of nine irremovable judges. I do not know of any more striking political paradox than this supremacy of a non-elected power in a democracy reputed to be of the extreme type. It is a power which is only renewed from generation to generation in the midst of a peculiarly unstable and constantly changing state of things--a power which in strictness could, by virtue of an authority now out of date, perpetuate the prejudices of a past age, and actually defy the changed spirit of the nation even in political matters."[88] It is a fundamental principle of free government that all legislative power should be under the direct control of the people. To make this control effective all laws must be enacted by the people themselves, or they must at least have what practically amounts to the power of appointing and removing their representatives. Democracy implies not merely the right of the people to defeat such laws as they do not want, but the power to compel such legislation as they need. The former power they possess in any country in which they control one coordinate branch of the legislature, even though the government be a monarchy or aristocracy. This negative power of defeating adverse legislation is merely the first step in the evolution of free government, and is possessed by the people in all countries which have made much constitutional progress. There is a vast difference, however, between a system under which the people constitute a mere check upon the government and one which gives them an active control over legislation. It is the difference between a limited monarchy or aristocracy on the one hand and a government by the people themselves on the other.[89]
