Ex- cept in the case of impeachments the judi- cial power of the United States is vested by the constitution in a supreme court and such other inferior courts as may be from time to time established by congress. All the judges are appointed by the president, with the advice of the senate, to hold office during good behavior, and their compen- sation cannot be diminished during their terms of office. The judges, other than those of the supreme court, are circuit judges and district judges, by whom are held the inferior courts of law and etuity. For a detailed description of the various courts and their rules of practice, jurisdiction, etc., it is suggested that reference be made to some recent book on the subject such as Dewhurst's Rules of Practice in the United States Courts, Montgomery's Federal Pro- cedure, or Foster's Federal Practice. Ed. Note.] The judicial power under the constitu- tion shall extend to:-1. Cases arising un- der the federal constitution, laws, or treaties. 2. Those affecting ambassadors and other public ministers and consuls. 8. Admiralty and maritime cases. 4. Con- troversies to which the United States is a party. 5. Those between two or more states. 6. Or between a state and a citizen of another state. (By the 11th amendment this grant of power was so limited as not to permit a state to be sued by citizens of another state, but a state may sue citizens of another state; 10 Wall. 553; 91 U. S. 667.) 7. Or between citizens of different states. 8. Or between a state or its citizens and foreign states, citizens, or subjects. This is construed to be an absolute grant of power; 1 Wheat. 308. The nature of the federal government which distributes the functions of govern- ment between two powers, each being sovereign within its sphere, but operating within the same territorial jurisdiction and upon the same persons and property, makes necessary the adjustment of two classes of independent tribunals with great care, both in legislation and the administration of justice, to avoid conflicts of jurisdiction. That such have occurred is true, but their rare occurrence in more than a century bears testimony as well to the tact and discretion of the judiciary, federal and state, as to the perfection of the system which they administer under the constitu- tion. As respects criminal proceedings, the courts of each jurisdiction generally con- fine themselves to the administration of the laws of the government which created them. In civil cases, however, as the con- stitution has conferred jurisdiction upon the federal courts in cases, for example, where a citizen of one state sues a citizen of another state, it is manifest that the court which tries such a case must ad- minister the laws of the state in which the action is brought, subject to the constitu- tion of the United States in cases which conflict with its provisions. In the organization of the federal system of courts, there were two objects to be ac- complished. The first was to prevent a clashing between the state and United States courts, by imposing restrictions upon the United States courts. The second was to carry out the mandates of the constitu- tion, by clothing the latter with all the powers necessary to execute its provisions. This organization was commenced by the act of 1789, familiarly known as the Judi- ciary Act; 1 Stat. at Large 921. To accomplish the first object, the right to issue writs of habeas corpus was by the fourteenth section limited to cases arising under the federal constitution and laws; R. S. § 758. See HABRAS CORPUS. This important restriction was intended to leave to the state authorities the ab- solute and exclusive administration of the state laws in all cases of imprisonment; and no instance hasever occurred in which this act has been disregarded. On the con- trary, its observance has been emphatic- ally enjoined and enforced; 21 How. 523. See 4 Dill. 833; 24 Am. L. Reg. 533. See infra. By the thirty-fourth section of the same act (R. S. § 721), it was enacted that the laws of the several states, except where the constitution, treaties, or statutes of the United States should otherwise require or provide, were to be regarded as rules of decision in trials at common law, in the courts of the United States, in cases where they applied. This provision has received examination and interpretation in the fol- lowing, among the many cases 7 How. 40; 8 id. 169; 14 id. 504; 17 id. 476; 18 id. 502, 507; 20 id. 393, 584; 18 Wall. 71: 17 id. 44; 98 U. S. 176, 242, 470; 3 Wash. C. C. 818; 17 Fed. Rep. 721. In'all cases de- pending upon the construction of a state statute, federal courts will follow the con- struction of the court of last resort of the state, when that construction is well settled, without respect to its original soundness: 9 Cra. 87; 100 U. S. 47; 60 Fed. Rep. 718; 22 id. 26; even when, in ignorance of a decision by the state court, the supreme court had construed the stat- ute differently; 100 U. S. 47
