List of United States Supreme Court cases, volume 40

In 1874, the U.S. government created the United States Reports, and retroactively numbered older privately-published case reports as part of the new series. As a result, cases appearing in volumes 1–90 of U.S. Reports have dual citation forms; one for the volume number of U.S. Reports, and one for the volume number of the reports named for the relevant reporter of decisions (these are called "nominative reports").

Richard Peters, Jr.

Starting with the 26th volume of U.S. Reports, the Reporter of Decisions of the Supreme Court of the United States was Richard Peters, Jr. Peters was Reporter of Decisions from 1828 to 1843, covering volumes 26 through 41 of United States Reports which correspond to volumes 1 through 16 of his Peters's Reports. As such, the dual form of citation to, for example, Levy v. Fitzpatrick is 40 U.S. (15 Pet.) 167 (1841).

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).^[2] 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 40 U.S. (15 Pet.) were decided the Court comprised nine justices at the start of the 1841 term, but only eight when it adjourned in March 1841; Justice Philip P. Barbour had died in February 1841.^[3]

The Schooner Amistad

The Schooner Amistad, 40 U.S. (15 Pet.) 518 (1841), resulted from the rebellion of kidnapped Africans on board the Spanish schooner La Amistad in 1839. It was an unusual freedom suit that involved international issues and parties as well as U.S. law. The lower courts ruled that the captives had acted as free men when they fought to escape their illegal confinement and were entitled to take whatever measures were necessary to secure their freedom, including the use of force. Under international and Southern sectional pressure, American President Martin Van Buren ordered the case appealed to the US Supreme Court, which affirmed the lower court ruling and authorized release of the captives.

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.
