Question: Are Graham v. Florida and Oregon v. Mitchell both Supreme Court cases?
Context: The Oregon Court of Appeals is the state intermediate appellate court in the US state of Oregon.  Part of the Oregon Judicial Department, it has thirteen judges and is located in Salem.  Except for death penalty cases, which are reserved to the Oregon Supreme Court, and tax court cases, it has jurisdiction to hear all civil and criminal appeals from Oregon circuit courts, and to review actions of most state administrative agencies.  The 13 judges of the court are chosen by the people in statewide nonpartisan elections to six-year terms, and have as their administrative head a Chief Judge appointed from their number by the Chief Justice of the state Supreme Court. Stephen P. Halbrook is a Senior Fellow at the Independent Institute and an author and lawyer known for his litigation on behalf of the National Rifle Association.  He has written extensively about the original meanings of the Second Amendment and the Fourteenth Amendment (the latter as applied to Second Amendment rights).  He has argued and won three cases before the US Supreme Court: "Printz v. United States", "United States v. Thompson-Center Arms Company", and "Castillo v. United States".  He has also written briefs in many other cases, including the Supreme Court cases "Small v. United States" (pertaining to the Gun Control Act of 1968) and "McDonald v. Chicago".  In "District of Columbia v. Heller", he wrote a brief on behalf of the majority of both houses of Congress.  More broadly, his decades of research on the Second Amendment contributed to the intellectual foundation of the "Heller" decision.  He has written many books and articles on the topic of gun control, some of which have been cited in Supreme Court opinions ("Heller", "McDonald", "Printz v. United States").  He has testified before congress on multiple occasions.  Halbrook’s most important scholarly contribution, however, was the book "That Every Man Be Armed", originally published in 1986.  The book was the most thorough analysis of the legal history and original intent of the Second Amendment. Graham v. Florida, 560 U.S. 48 (2010) , was a decision by the Supreme Court of the United States holding that juvenile offenders cannot be sentenced to life imprisonment without parole for non-homicide offenses.  The court decided that "Roper v. Simmons" (2005), which had abolished the death penalty for juvenile offenders as unconstitutional, should apply also to sentences of life without the possibility of parole. Spaziano v. Florida, was two United States Supreme Court cases dealing with the imposition of the death penalty.  In the first case, 454 U.S. 1037 (1981), the Supreme Court, with two dissents, refused Spaziano's petition for certiorari.  However, the Florida Supreme Court would reverse Spaziano's death sentence based on the judge's receipt of a confidential report which was not received by either party.  On remand, the judge reimposed the death penalty and the Florida Supreme Court upheld the sentence.  In the second case, 468 U.S. 447 (1984) the Court heard Spaziano's appeal of his death sentence. Evans v. Jordan, 13 U.S. 199 (1815) , was a United States Supreme Court case in which the Court held that someone who had copied a patented invention after the patent had expired, and before the patent was restored by a private bill, would be liable for damages for patent infringement for any use continuing after the patent was restored.  It was the second published Supreme Court decision on patent law, and the first of four Supreme Court cases dealing with the Oliver Evans flour mill patent.  Like other Supreme Court patent cases prior to "Evans v. Eaton", however, this case did not deal with substantive patent law, but only with issues of statutory construction and infringement liability. 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". Westendorp v R, [1983] 1 S.C.R. 43 was a decision of the Supreme Court of Canada on the scope of the federal Parliament's criminal law power under section 91(27) of the Constitution Act, 1867.  A unanimous Court found that a municipal by-law that prohibited standing in the street for the purpose of prostitution was in the nature of a criminal law prohibition and therefore ultra vires of the provincial constitutional authority.  The decision surprised many legal scholars who considered it to be inconsistent with previous Supreme Court cases where provincial laws of a moral nature were upheld under the provincial power (see "Canada (AG) v Montreal (City of)", [1978] and "Nova Scotia (Board of Censors) v McNeil" [1978]).  This was also the first case where the "Canadian Charter of Rights and Freedoms" was cited in argument to the Supreme Court, although the Charter argument was ultimately abandoned during the hearing. Pierce, Governor of Oregon, et al. v. Society of the Sisters of the Holy Names of Jesus and Mary, 268 U.S. 510 (1925) , was an early 20th-century United States Supreme Court decision striking down an Oregon statute that required all children to attend public school.  The decision significantly expanded coverage of the Due Process Clause in the Fourteenth Amendment to the United States Constitution to recognize personal civil liberties.  The case has been cited as a precedent in more than 100 Supreme Court cases, including "Roe v. Wade", and in more than 70 cases in the courts of appeals. Hollingsworth v. Perry refers to a series of United States federal court cases that legalized same-sex marriage in the State of California.  The case began in 2009 in the U.S. District Court for the Northern District of California, which found that banning same-sex marriage violates equal protection under the law.  This decision overturned ballot initiative Proposition 8, which had banned same-sex marriage.  After the State of California refused to defend Proposition 8, the official sponsors of Proposition 8 intervened and appealed to the Supreme Court.  The case was litigated during the governorships of both Arnold Schwarzenegger and Jerry Brown, and was thus known as Perry v. Schwarzenegger and Perry v. Brown, respectively.  As "Hollingsworth v. Perry", it eventually reached the United States Supreme Court, which held that, in line with prior precedent, the official sponsors of a ballot initiative measure did not have Article III standing to appeal an adverse federal court ruling when the state refused to do so. During the tenure of Morrison Waite as Chief Justice of the Supreme Court of the United States (March 4, 1874 through March 23, 1888), the Supreme Court heard an unprecedented volume and frequency of criminal cases.  In just fourteen years, the Court heard 106 criminal cases, almost as many cases as the Supreme Court had heard in the period from its creation to the appointment of Waite as Chief Justice.  Notable cases include "United States v. Cruikshank" (1875), "United States v. Reese" (1875), "Reynolds v. United States" (1878), "Wilkerson v. Utah" (1879), the "Trade-Mark Cases" (1879), "Strauder v. West Virginia" (1880), "Pace v. Alabama" (1883), "United States v. Harris" (1883), "Ex parte Crow Dog" (1883), "Hurtado v. California" (1884), "Clawson v. United States" (1885), "Yick Wo v. Hopkins" (1886), "United States v. Kagama" (1886), "Ker v. Illinois" (1886), and "Mugler v. Kansas" (1887).
