1. This is the highest tribunal in the United States. If the whole government be figuratively regarded as an arch this is the “Key Stone of the Arch” without which the whole structure would crumble and fall. In all cases of dispute as to the meaning of the Constitution and the range of powers it confers, or implies, it has sovereign power to decide; and from that decision there is no appeal. Its declaration, as to the meaning and application of the Constitution and the body of statutes enacted under it, becomes the law of the land. It is the great bulwark against tyrannical use of power, and conflicting enactments, whether by National or State Legislatures. 2. This court has one Chief Justice and nine Associate Justices, all appointed by the President, by and with the advice and consent of the Senate. They are appointed for life, or during good behavior; they may be impeached for bribery or other high crimes, and then removed from office. They may also resign; but if they conduct themselves properly and choose to retain their offices, there is no power by which they can be removed, except the power of death. The Constitution itself makes this provision, in order that the judges may be removed as far as possible from the influence of party politics. It is therefore expected that their decisions will not be biased by party or political considerations; and it may not be amiss to say that the provisions for keeping the judges of the United States Courts in office for life, meets with almost universal approbation; and has caused many to hope that the States would alter their Constitutions and adopt the same plan; believing it to be the surest way of preserving a pure and[429] independent Judiciary, on which depend the rights and liberties of every citizen of the commonwealth.
3. This court holds but one term in a year, which commences on the first Monday of December, and sits until it has disposed of the business before it. Its sessions are always held at Washington, the capital of the nation; there it has access to the Congressional and Law Libraries, and to all the departments and records of the government when necessary.
There is a class of causes which may be commenced in this court. In these cases it has original jurisdiction. They are such as affect ambassadors, other public ministers, and consuls; and those in which a State shall be a party. In other cases it has only appellate jurisdiction. The greater part of its business is to hear and determine appeals from inferior courts, mainly from the United States Circuit Courts; and in some instances from the highest State courts.
4. It has not only original, but exclusive jurisdiction in causes where a State is a party, and when proceedings or suits against ambassadors, or other public ministers or their servants, are instituted. Its power to try appeals from lower courts, called appellate jurisdiction, gives it the position of the highest court in............
