The Circuit Court of Appeals is held by three judges, two constituting a quorum. Those generally sitting are the Circuit Judges belonging to the circuit. The Justice of the Supreme Court assigned to the circuit may also sit, and any of the District Judges in the circuit can be called in. Except in a very limited class of cases, the decision of this court is final, unless the Supreme Court, on special application, should think the questions involved to be of sufficient importance to require a review, when it can order the record sent up to Washington for that purpose. The Circuit Court of Appeals can also of its own motion certify up any questions in a cause to the Supreme Court for its instructions before making a final disposition of it. The Supreme Court has direct appellate jurisdiction over the District and Circuit Courts in cases turning on the limits of their jurisdiction, in prize causes, in equity suits by the United States under the statutes regulating inter-State commerce, and in all cases involving the construction or application of the Constitution of the United States, or of a treaty. Appeals also lie to it from judgments of conviction in the Circuit Court for capital offenses.[Footnote: 29 U. S. Statutes at Large, 492; 32 _ib_. 823.] The consequence of the Circuit Courts, which had been impaired by the practical withdrawal of the justices of the Supreme Court, was further lessened by the creation of the Circuit Court of Appeals. Before that their judgments in most cases were final. In criminal causes there was no appeal, and in ordinary civil causes none after 1875, unless the matter in controversy exceeded $5,000 in value. This left the life, liberty and property of the citizen top much in the hands of one man; and the people, led by the bar, insisted on stripping him of powers so liable to abuse.[Footnote: See an attack on a similar state of things existing in Louisiana at one time in the District Court, by Edward Livingston in 1826. Hunt, "Life of Edward Livingston," 302, 303.] No sovereign can be sued in his own courts without his consent. The United States consent to be sued on most claims against them of a contractual nature, which they may dispute. For this purpose a Court of Claims has been established at Washington, consisting of a Chief Justice and four associates. Originally it was little more than an administrative bureau; but by successive amendments of the law it has come to have fully a judicial character,[Footnote: United States _v._ Klein, 13 Wallace's Reports, 128, 144; 24 U. S. Statutes at Large, 505.] except in one particular. It is a general principle that a court will make no decree that it cannot enforce. The Court of Claims cannot issue an execution to enforce its judgments. Money can be drawn from the treasury of the United States only to meet appropriations made by Congress. An appropriation is made by each Congress of a gross sum to satisfy any judgments that have
