Until 1911, the District Courts had a narrow jurisdiction, and there were Circuit Courts having a wider one. In 1911, the Circuit Court was abolished, and the District Court now is the general trial court of the United States in the first instance. Anyone can sue there to enforce a right arising under the laws of the United States when the amount in dispute is more than $3,000. Rights arising under certain of these laws can only be enforced there, and as to them the pecuniary limitation does not apply. Such are patent-rights and copyrights. Any suit involving an amount exceeding $3,000 may be brought there when the controversy is between citizens of different States or citizens of a State and citizens of a foreign country. So may a suit by citizens of the same State claiming land under grants from different States, without respect to the value of the subject of controversy. Suits of any of these kinds which are brought in a State court may, at the option of the defendant, be transferred for trial into the District Court. On filing proper papers the case is transferred automatically. The District Court has jurisdiction also over bankruptcy and admiralty matters, a few other kinds of civil cases of minor importance, and of all offenses against the United States.[Footnote: The Judicial Code of the United States, Chapter II.] The pecuniary limit of jurisdiction was for a hundred years fixed at $500. The increase to $3,000 was due partly to the fact that the Supreme Court was overburdened by appeals from the trial courts, many of which involved small amounts, and more to a desire to keep judicial power over ordinary controversies between man and man, as far as practicable, in the hands of the State courts. Early in the nineteenth century a practice began of bringing suits in the Circuit Court of the United States, which purported to be between citizens of different States, but in which the plaintiff had either changed his residence for the purpose of giving the court jurisdiction or was really suing for the benefit of a citizen of the same State with the defendant. This was due to the high opinion entertained of the federal judiciary[Footnote: Niles' Register, XXIX, 14.] and the desire to bring the cause before a federal, rather than a State tribunal. Such a mode of proceeding, while within the letter of the governing statute, was contrary to its spirit, and little better than a fraud. It was also an evident perversion of the intent of the Constitution, and became at last so far-spreading that both Congress and the courts used their best endeavors to put an end to it, and with success.[Footnote: U. S. Statutes at Large, XVIII, 470; Hawes _v._ Oakland, 104 U. S., 450, 459.]
