Oregon v. Mitchell, 400 U.S. 112 (1970) was a Supreme Court case which held that the United States Congress could set voting age requirements for federal elections but not for local or state elections.
 The case also upheld Congress's nationwide prohibition on literacy tests and similar "tests or devices" used as voting qualifications as defined in the "Voting Rights Act of 1965".
Oregon v. Bradshaw, 462 U.S. 1039 (1983) , applied the rule first announced in "Edwards v. Arizona" (1981) and clarified the manner in which a suspect may waive his right under "Miranda v. Arizona" (1966) to have counsel present during interrogation by the police.
Boynton v. Virginia, 364 U.S. 454 (1960) was a decision by the Supreme Court of the United States.
 The case overturned a judgment convicting an African American law student for trespassing by being in a restaurant in a bus terminal which was "whites only".
 It held that racial segregation in public transportation was illegal because such segregation violated the Interstate Commerce Act, which broadly forbade discrimination in interstate passenger transportation.
 It moreover held that bus transportation was sufficiently related to interstate commerce to allow the United States federal government to regulate it to forbid racial discrimination in the industry.
Mitigating evidence is evidence that is provided (usually by the defendant in a criminal trial) in order to try to establish the presence of mitigating circumstances.
 The presence of mitigating circumstances can reduce the punishment imposed for the offense.
 The case of the "Oregon v. Guzek" dealt with the issue of whether alibi evidence not introduced at trial could be introduced in the sentencing phase of a death penalty trial as mitigating evidence.
Freedom Riders were civil rights activists who rode interstate buses into the segregated southern United States, in 1961 and subsequent years, in order to challenge the non-enforcement of the United States Supreme Court decisions "Morgan v. Virginia" (1946) and "Boynton v. Virginia" (1960), which ruled that segregated public buses were unconstitutional.
 The Southern states had ignored the rulings and the federal government did nothing to enforce them.
 The first Freedom Ride left Washington, D.C., on May 4, 1961, and was scheduled to arrive in New Orleans on May 17.
Margaret Winonah Beamer Myers (born September 10, 1941) is an American political activist, who, in 1961 at the age of 19, became a Freedom Rider.
 Freedom Riders were civil rights activists who rode interstate buses into the segregated southern United States in 1961 and following years to challenge the non-enforcement of the United States Supreme Court decisions "Irene Morgan v. Commonwealth of Virginia" (1946) and "Boynton v. Virginia" (1960).
 She was arrested in Jackson, Mississippi and spent almost six months in Mississippi State Penitentiary, better known as Parchman Farm, the oldest prison and the only maximum-security prison for men in the state of Mississippi.
 Of all the Freedom Riders, white or black, Winonah Beamer served the longest sentence and was the only Freedom Rider who served her full term.
The National Clearinghouse on Marital and Date Rape was a research center that compiled and provided information on date and marital rape cases, and on legislation regarding them, and media publications on these subjects, as well as acting as an advocate for marital and date rape victims.
 It began in 1978 as a project of the Women's History Research Center, with Laura X as its director.
 It published a pamphlet on the landmark 1978 Oregon v. Rideout case, in which a man was acquitted of raping his wife; the case was the first time in American history a husband was tried for raping his wife while they were living together.
 In 1983 the National Clearinghouse on Marital and Date Rape conducted the world's first conference on marital rape.
 In 2004 the Clearinghouse closed, but it maintains its website for posterity.
Oregon v. Ice, 555 U.S. 160 (2009), was a legal case in which the Supreme Court of the United States held that the Sixth Amendment to the United States Constitution does not inhibit states from assigning to judges, rather than juries, the finding of facts necessary to the imposition of consecutive, rather than concurrent, sentences for multiple offenses.
John Hipple Mitchell, also known as John Mitchell Hipple, John H. Mitchell, or J. H. Mitchell (June 22, 1835December 8, 1905) was a controversial American lawyer and politician, who served as a Republican United States Senator from Oregon on three occasions between 1873 and 1905.
 He also served as State Senate President, did the initial legal work involved in the dispute that led to the landmark Supreme Court case of "Pennoyer v. Neff", and later was involved with the Oregon land fraud scandal, for which he was indicted and convicted while a sitting U.S. Senator, one of only twelve sitting U.S. Senators ever indicted, and one of only five ever convicted.
Employment Division, Department of Human Resources of Oregon v. Smith, 494 U.S. 872 (1990) , is a United States Supreme Court case that held that the state could deny unemployment benefits to a person fired for violating a state prohibition on the use of peyote, even though the use of the drug was part of a religious ritual.
 Although states have the "power" to accommodate otherwise illegal acts performed in pursuit of religious beliefs, they are not "required" to do so.
