The Court outlined the basic standards for determining competency.
Document 2: Richard Nixon: Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th President of the United States from 1969 until 1974, when he resigned from office, the only U.S. president to do so. He had previously served as the 36th Vice President of the United States from 1953 to 1961, and prior to that as a U.S. Representative and also Senator from California.
Document 3: Aptheker v. Secretary of State: Aptheker v. Secretary of State, 378 U.S. 500 (1964) , was a landmark United States Supreme Court case on the right to travel and passport restrictions as they relate to Fifth Amendment due process rights and First Amendment free speech, freedom of assembly and freedom of association rights. It is the first case in which the US Supreme Court considered the constitutionality of personal restrictions on the right to travel abroad.
Document 4: New York Times Co. v. United States: New York Times Co. v. United States, 403 U.S. 713 (1971), was a landmark decision by the United States Supreme Court on the First Amendment. The ruling made it possible for "The New York Times" and "The Washington Post" newspapers to publish the then-classified "Pentagon Papers" without risk of government censorship or punishment.
Document 5: Nixon v. General Services Administration: Nixon v. General Services Administration, 433 U.S 425 (1977), is a landmark court case concerning the principle of presidential privilege and whether the public is allowed to view a President’s “confidential documents”. The Presidential Recordings and Materials Preservation Act, signed into law by President Gerald Ford in 1974, ordered that the Administrator of General Services obtain President Richard Nixon’s presidential papers and tape recordings. In addition, the Act further ordered that government archivists seize these materials. These archivists would preserve the material deemed historic and return to former President Nixon the materials deemed as private. Furthermore, this Act stated that material that was preserved could be used in judicial hearings and proceedings. Immediately after this Act was enacted, Richard Nixon filed a lawsuit in a federal district court claiming that the Act violated the principle of separation of powers, the principle of presidential privilege, Nixon’s personal privacy, his First Amendment right of association, and further asserted that it amounted to a constitutionally prohibited Bill of Attainder.
Document 6: United States v. R. Enterprises, Inc.: United States v. R. Enterprises, Inc., 498 U.S. 292 (1991), was a United States Supreme Court case in which the court held that the three prong test for the issuance of a subpoena in "United States v. Nixon" does not apply to subpoenas issued by a grand jury. The Court concluded by stating that when a grand jury subpoena is challenged on relevancy grounds, the motion to quash must be denied “unless the district court determines that there is no reasonable possibility that the materials sought will produce information relevant to the grand jury's investigation.”
Document 7: United States v. Guest: United States v. Guest 383 U.S. 745 (1966) is a United States Supreme Court opinion, authored by Justice Potter Stewart, in which the court extended the protection of the 14th Amendment to citizens who suffer rights deprivations at the hands of private conspiracies, where there is minimal state participation in the conspiracy. The Court also held that there is Constitutional right to travel from state to state.
Document 8: Richard Nixon: Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th President of the United States from 1969 until 1974, when he resigned from office, the only U.S. president to do so. He had previously served as the 36th Vice President of the United States from 1953 to 1961, and prior to that as a U.S. Representative and also Senator from California.
Document 9: Watergate scandal: The Watergate scandal was a major political scandal that occurred in the United States in the early 1970s, following a break-in at the Democratic National Committee (DNC) headquarters at the Watergate office complex in Washington, D.C. on June 17, 1972, and President Richard Nixon’s administration’s attempted cover-up of its involvement. When the conspiracy was discovered and investigated by the U.S. Congress, the Nixon administration’s resistance to its probes led to a constitutional crisis.
Document 10: Kent v. Dulles: Kent v. Dulles, 357 U.S. 116 (1958) , was a landmark United States Supreme Court case on the right to travel and passport restrictions as they relate to First Amendment free speech rights. It was the first case in which the U.S. Supreme Court made a distinction between the constitutionally protected substantive due process "freedom of movement" and the "right to travel abroad" (subsequently characterized as "right to international travel".
Document 11: Freedom of movement under United States law: Freedom of movement under United States law is governed primarily by the Privileges and Immunities Clause of the United States Constitution which states, "The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States." As far back as the circuit court ruling in "Corfield v. Coryell," 6 Fed. Cas. 546 (1823), freedom of movement has been judicially recognized as a fundamental Constitutional right. In "Paul v. Virginia," 75 U.S. 168 (1869), the Court defined freedom of movement as "right of free ingress into other States, and egress from them." However, the Supreme Court did not invest the federal government with the authority to protect freedom of movement. Under the "privileges and immunities" clause, this authority was given to the states, a position the Court held consistently through the years in cases such as "Ward v. Maryland," 79 U.S. 418 (1871), the "Slaughter-House Cases," 83 U.S. 36 (1873) and "United States v. Harris," 106 U.S. 629 (1883).
Document 12: Gravel v. United States: Gravel v. United States, 408 U.S. 606 (1972), was a case regarding the protections offered by the Speech or Debate Clause of the United States Constitution. In the case, the Supreme Court of the United States held that the privileges and immunities of the Constitution's Speech or Debate Clause enjoyed by members of Congress also extend to Congressional aides, but not to activity outside the legislative process.
Document 13: United States v. Nixon: United States v. Nixon, 418 U.S. 683 (1974), was a landmark United States Supreme Court decision which resulted in a unanimous 8–0 ruling against President Richard Nixon, ordering him to deliver presidential tape recordings and other subpoenaed materials to the District Court. Issued on July 24, 1974, the ruling was important to the late stages of the Watergate scandal, when there was an ongoing impeachment process against Richard Nixon. "United States v. Nixon" is considered a crucial precedent limiting the power of any U.S. president to claim executive privilege.
Document 14: Impeachment process against Richard Nixon: An impeachment process against Richard Nixon was formally initiated on February 6, 1974, when the United States House of Representatives passed a resolution, , giving its Judiciary Committee authority to investigate whether sufficient grounds existed to impeach Richard Nixon, the 37th President of the United States of high crimes and misdemeanors, primarily related to the Watergate scandal. This investigation was undertaken one year after the United States Senate established a select committee to investigate the 1972 break-in at the Democratic National Committee headquarters at the Watergate office complex in Washington, D.C. and the Nixon Administration's attempted cover-up of its involvement.
Document 15: United States v. Wheeler (1920): United States v. Wheeler, 254 U.S. 281 (1920), is an 8-to-1 ruling by the Supreme Court of the United States that held that the Constitution alone did not grant the federal government the power to prosecute kidnappers, and only the states had the authority to punish a private citizen's unlawful violation of another's freedom of movement. The case was a landmark interpretation of the Privileges and Immunities Clause of the Constitution, and contained a classic legal statement of the right to travel which continues to undergird American jurisprudence.
