Each fully organized Territory has a set of local courts and one Supreme Court to which appeals can be taken and the judgments of which, in cases of large pecuniary magnitude or great legal importance, can be reviewed by the Supreme Court of the United States. These territorial courts do not exercise what is known in the strict sense and designated in the Constitution as "the judicial power of the United States." They are created to meet temporary conditions, and with judges whose commissions run only for a few years. Such courts are instruments through which Congress exercises its power of regulating the territory of the United States. They act judicially. They have judicial power. But the source of this power is not the clause in the Constitution under which the judicial power of the United States is defined.[Footnote: American Insurance Co. _v._ Canter, 1 Peters' Reports, 511.] It is therefore not necessary to confine such courts strictly to the consideration of judicial business. In the organization of our earliest Territories the judges were given legislative functions, and while this was originally due to the terms of the Ordinance of 1787, it was confirmed by various Acts of Congress after the adoption of the Constitution of the United States. The Philippines are governed under an Act of Congress by a commission acting under the supervision of the Secretary of War. The organization of courts established by Spain has been in substance preserved. The Spanish law which was in force there was expressed in codes mainly founded on those framed for France under Napoleon I. In 1901, the Spanish code of civil procedure was supplanted by one prepared by a member of the Philippine Commission, and which is now familiarly known by his name as the Ide Code. In substance, it establishes the mode of proceeding in civil cases which is known in the United States as code pleading. Trial by jury has not been introduced into the Philippines either in civil or criminal causes, and need not be.[Footnote: Dorr _v._ United States, 195 U. S. Reports, 138.] In criminal causes, the Spanish system was originally retained, allowing either party, the United States or the defendant, to appeal from the judgment of the court of first instance to the Supreme Court of the islands and have there a new hearing both as to fact and law. This, however, so far as concerns an appeal by the government, was held to be contrary to the Act of Congress under which it was constituted.[Footnote: Kepner _v._ United States, 195 U. S. Reports, 100.] The courts of the United States are generally provided with an officer styled a marshal. He executes their process, attends their sessions, and exercises in general the functions which belong to a sheriff as respects State courts.
