been or may be rendered by the Court of Claims; but should this provision be omitted in any appropriation bill the judgments of the Court of Claims could not be collected. Concurrent jurisdiction in these respects is given to the District Court of claims not exceeding $1,000 in amount, and to the Circuit Court of those exceeding $1,000 and not exceeding $10,000. Aliens can sue in the Court of Claims when their own country accords a similar privilege in its courts to citizens of the United States.[Footnote: U. S. Revised Statutes, Sec. 1068.] This court has also a peculiar kind of advisory jurisdiction. Congress, or any committee of either house, can refer to it any questions of fact which may have come before them. The judges must then ascertain the facts and report them back. The head of any of the great executive departments may, in like manner, in dealing with any claim against the government, if the claimant consents, refer any uncontroverted questions, either of fact or law, to the court, which must then report back to him its findings and opinion. This does not take the form of a judgment, for there is no case and no parties are before it. It is a mere expression of opinion, and stands on much the footing of the report of a committee of inquiry to a superior authority.[Footnote: 22 U. S. Statutes at Large, 485; 24 _id._, 507.] A temporary court is also in existence called the Court of Private Land Claims. This is composed of a Chief Justice and four associate justices, and has jurisdiction to hear and determine claims of title to land as against the United States, founded on Spanish or Mexican grants in New Mexico, Arizona, Utah, Nevada, Colorado or Wyoming. An appeal from the final judgment is given to the Supreme Court of the United States.[Footnote: 26 U. S. Statutes at Large, 854.] The District of Columbia has a special judicial establishment. There is a court of general jurisdiction known as the Supreme Court of the District of, Columbia, and appeals from its judgments lie to the Court of Appeals of the District of Columbia. This is composed of a Chief Justice and two associate justices, and its judgments are reviewable by the Supreme Court of the United States, if $5,000 is involved, or the validity of an authority exercised under the United States or a treaty or Act of Congress is in question. An appeal also lies to it from decisions of the Commissioner of Patents as to claims of a right to a patent.[Footnote: 27 U. S. Statutes at Large, 434.] When new territory comes by conquest or cession permanently under the jurisdiction of the United States, it belongs to the President, in the exercise of his executive power, to see to its proper government until Congress makes other provision. He can institute courts there for that purpose, or if he finds courts created by the former sovereign in existence, can expressly or impliedly permit them to continue in the exercise of judicial functions.
