United States v. Morrison, 529 U.S. 598 (2000) , is a United States Supreme Court decision which held that parts of the Violence Against Women Act of 1994 were unconstitutional because they exceeded congressional power under the Commerce Clause and under section 5 of the Fourteenth Amendment to the Constitution
The Taney Court (1836–1864) heard thirty criminal law cases, approximately one per year.
 Notable cases include "Prigg v. Pennsylvania" (1842), "United States v. Rogers" (1846), "Ableman v. Booth" (1858), "Ex parte Vallandigham" (1861), and "United States v. Jackalow" (1862).
United States v. Bell Telephone Co., 167 U.S. 224 (1897), is an 1897 decision of the United States Supreme Court that held that the United States lacked standing to challenge the validity of its issued patents “on the mere ground of error of judgment” in issuing them.
 The United States had standing to seek to invalidate patents, however, on grounds of fraudulent procurement and also as a defense to a charge of patent infringement.
 The decision operated for many decades as a bar to government efforts to seek invalidation of patents that it considered spurious until the Supreme Court limited "Bell Telephone", first to a limited extent in "United States v. United States Gypsum Co.", and then more broadly in "United States v. Glaxo Group Ltd."
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.
Dannel McCollum was the mayor of Champaign, Illinois from 1987-1999.
 He is the author of the book "The Lord Was Not on Trial" about his mother Vashti McCollum's landmark 1948 Supreme Court case McCollum v. Board of Education, which struck down religious education in public schools.
 He also wrote the book "Remembering Champaign County".
On April 28, 2015, the Supreme Court of the United States heard oral arguments for "Obergefell v. Hodges" (Ohio), which was consolidated with three other same-sex marriage cases from the other states in the Sixth Circuit: "Tanco v. Haslam" (Tennessee), "DeBoer v. Snyder" (Michigan), "Bourke v. Beshear" (Kentucky).
 On June 26, 2015 the Supreme Court reversed the Sixth Circuit's decision, paving the way for same-sex marriage to become legal in those states, and setting a precedent for the entire nation.
 All four states complied with the ruling the same day it was issued before the mandate was actually issued.
 Every state in the circuit had a district court ruling against their states' ban, but they were eventually stayed pending appeal.
 The Sixth Circuit consists of Kentucky, Michigan, Ohio, and Tennessee.
 On August 6, 2014, the Sixth Circuit heard oral arguments for same-sex marriage cases from each state within the circuit.
 On November 6, 2014, the Sixth Circuit in a split 2-1 decision, upheld the states' same-sex marriage bans, reversing the district courts' rulings that struck them down.
 The Sixth Circuit was the first and only circuit court since the landmark ruling "United States v. Windsor" to uphold the constitutionality of states' same-sex marriage bans which caused a circuit split.
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).
Vashti Cromwell McCollum (November 6, 1912 – August 20, 2006) was the plaintiff in the landmark 1948 Supreme Court case McCollum v. Board of Education, which struck down religious education in public schools.
 The defendant in the case was the public school district of Champaign, Illinois; instructors chosen by three religious faiths had taught religion classes within the district's schools.
McCollum v. Board of Education, 333 U.S. 203 (1948), was a landmark 1948 United States Supreme Court case related to the power of a state to use its tax-supported public school system to aid religious instruction.
 The case was a test of the separation of church and state with respect to education.
The Marshall Court (1801–1835) heard forty-one criminal law cases, slightly more than one per year.
 Among such cases are "United States v. Simms" (1803), "United States v. More" (1805), "Ex parte Bollman" (1807), "United States v. Hudson" (1812), "Cohens v. Virginia" (1821), "United States v. Perez" (1824), "Worcester v. Georgia" (1832), and "United States v. Wilson" (1833).
