The Supreme Court is established by Article III, Section 1 of the Constitution of the United States, which says: "The judicial Power of the United States, shall be vested in one supreme Court . . .". The size of the Court is not specified; the Constitution leaves it to Congress to set the number of justices. Under the Judiciary Act of 1789 Congress originally fixed the number of justices at six (one chief justice and five associate justices).^[1] Since 1789 Congress has varied the size of the Court from six to seven, nine, ten, and back to nine justices (always including one chief justice).

When the cases in volume 134 U.S. were decided the Court comprised the following nine members:

Hans v. Louisiana edit

In Hans v. Louisiana, 134 U.S. 1 (1890), the Supreme Court held that the Eleventh Amendment prohibits a citizen of a U.S. state from suing their own state in a federal court. The Court suggested that the framers of the Constitution had not addressed the possibility of a citizen suing his own state because such a thing would simply be inconceivable to them. At the time the Constitution was written, states had always been immune from such suits, unless the state itself consented to be sued. Furthermore, the Judiciary Acts of 1789 and 1802 had granted the federal courts jurisdiction "concurrent with the courts of the several states," indicating that Congress had not contemplated the possibility that the federal courts would have any powers unknown to the state courts.

Under the Judiciary Act of 1789 the federal court structure at the time comprised District Courts, which had general trial jurisdiction; Circuit Courts, which had mixed trial and appellate (from the US District Courts) jurisdiction; and the United States Supreme Court, which had appellate jurisdiction over the federal District and Circuit courts—and for certain issues over state courts. The Supreme Court also had limited original jurisdiction (i.e., in which cases could be filed directly with the Supreme Court without first having been heard by a lower federal or state court). There were one or more federal District Courts and/or Circuit Courts in each state, territory, or other geographical region.
