Judiciary Act of 1789 in the context of "Supreme Court of the United States"

Article Three of the United States Constitution establishes the judicial branch of the U.S. federal government. Under Article Three, the judicial branch consists of the Supreme Court of the United States, as well as lower courts created by Congress. Article Three empowers the courts to handle cases or controversies arising under federal law, as well as other enumerated areas. Article Three also defines treason.

Section 1 of Article Three vests the judicial power of the United States in "one supreme Court", as well as "inferior courts" established by Congress. Section 1 authorizes the creation of inferior courts, but does not require it; the first inferior federal courts were established shortly after the ratification of the Constitution with the Judiciary Act of 1789. Section 1 also establishes that federal judges do not face term limits, and that an individual judge's salary may not be decreased. Article Three does not set the size of the Supreme Court or establish specific positions on the court, but Article One establishes the position of chief justice. Along with the Vesting Clauses of Article One and Article Two, Article Three's Vesting Clause establishes the separation of powers among the three branches of government.

The United States circuit courts were the intermediate level courts of the United States federal court system from 1789 until 1912. They were established by the Judiciary Act of 1789, and had trial court jurisdiction over civil suits of diversity jurisdiction and major federal crimes. They also had appellate jurisdiction over the United States district courts. The Judiciary Act of 1891 (26 Stat. 826, also known as the Evarts Act) transferred their appellate jurisdiction to the newly created United States circuit courts of appeals, which are now known as the United States courts of appeals. On January 1, 1912, the effective date of the Judicial Code of 1911, the circuit courts were abolished, with their remaining trial court jurisdiction transferred to the U.S. district courts.

During the 100 years that the Justices of the U.S. Supreme Court "rode circuit", many justices complained about the effort required. Riding circuit took a great deal of time (about half of the year) and was both physically demanding and dangerous. However, "members of Congress held firm to the belief that circuit riding benefited the justices and the populace, and they turned a deaf ear to the corps of justices that desired to abolish the practice."

The United States Marshals Service (USMS) is a federal law enforcement agency in the United States. The Marshals Service serves as the enforcement and security arm of the U.S. federal judiciary. It is an agency of the U.S. Department of Justice and operates under the direction of the U.S. attorney general. U.S. Marshals are the original U.S. federal law enforcement officers, created by the Judiciary Act of 1789 during the presidency of George Washington as the "Office of the United States Marshal" under the U.S. district courts. The USMS was established in 1969 to provide guidance and assistance to U.S. Marshals throughout the federal judicial districts.

The Marshals Service is primarily responsible for locating and arresting federal suspects, the administration of fugitive operations, the management of criminal assets, the operation of the United States Federal Witness Protection Program and the Justice Prisoner and Alien Transportation System, the protection of federal courthouses and judicial personnel, and the protection of senior government officials through the Office of Protective Operations. Throughout its history the Marshals have also provided unique security and enforcement services including protecting African American students enrolling in the South during the civil rights movement, escort security for United States Air Force LGM-30 Minuteman missile convoys, law enforcement for the United States Antarctic Program, and protection of the Strategic National Stockpile.
