Same-sex marriage by Circuit Court: Prior to the landmark ruling "United States v. Windsor", the constitutionality of banning same-sex marriage was upheld by the Eighth Circuit in "Citizens for Equal Protection v. Bruning".  After the "Windsor" ruling, many same-sex marriage bans were struck down by lower courts.  The Tenth, Fourth, Seventh, and Ninth circuits all ruled that same-sex marriage bans were unconstitutional.  The cases that made it to these circuit courts originated in district courts which for the most part also struck down same-sex marriage bans.  When a circuit court struck down a state's same-sex marriage ban, it did not directly strike down same-sex marriage bans in other states within the circuit.  However, it paved the way for same-sex marriage bans to be struck down in the entire circuit due to the precedent it set for district courts within the circuit to follow.  In some states, same-sex marriage was already legal before a federal circuit court ruled on the matter.  The Sixth Circuit ruled that same-sex marriage bans were not unconstitutional and reversed the district court rulings that struck down same-sex marriage bans.  Since this was the only circuit court to rule this way post-"Windsor", this created a circuit split which ultimately led to the Supreme Court of the United States deciding to resolve the issue once and for all.  They ruled that same-sex marriage bans violate the constitution in the landmark ruling "Obergefell v. Hodges" which was the consolidated case that covered each state in the Sixth Circuit.  Some circuit courts have not ruled on the constitutionality of same-sex marriage bans at all.  Many circuit courts had pending same-sex marriage cases, but decided to hold off on litigation until the Supreme Court ruled on the matter.

Adickes v. S. H. Kress &amp; Co.: Adickes v. S. H. Kress & Co., 398 U.S. 144 (1970), was a United States Supreme Court case where the majority ruling, written by Justice Harlan, asserted that the burden of showing a lack of factual controversy rests upon the party asserting the summary judgment.  It was later challenged by "Celotex Corp. v. Catrett" (1986), but the case was not officially overruled.

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.

United States v. Binion: United States v. Binion, 132 F. App'x 89 (8th Cir.  2005), is a case in which the United States Court of Appeals for the Eighth Circuit applied two recent U.S. Supreme Court decisions ("United States v. Booker", 543 U.S. 220 (2005) and "United States v. Fanfan", 543 U.S. 220 (2005) in reviewing the sentencing decision by the trial court and upheld by the Federal District Court for the Eastern District.

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.

Marie Louise v. Marot: Marie Louise v. Marot (1836) was a freedom suit heard by the Louisiana state district court and appealed to the Louisiana Supreme Court.  The Court held that a slave who is taken to a territory prohibitive of slavery cannot be again reduced to slavery on returning to a territory allowing of slavery.  The ruling was cited as precedent to the 1856 landmark "Dred Scott v. Sandford" case heard by the U.S. Supreme Court.  Supreme Court Justice John McLean cited the precedent in his dissent of the majority ruling.  Six of eight justices did not abide by the precedent in what has been considered the worst decision ever made by the Supreme Court.

Same-sex marriage in the Sixth Circuit: 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.

Stromberg v. California: Stromberg v. California, 283 U.S. 359 (1931) was a United States Supreme Court case in which the Court ruled 7–2 that a 1919 California statute banning red flags was unconstitutional because it violated the First and Fourteenth Amendments to the United States Constitution.  This decision is considered a landmark in the history of First Amendment constitutional law, as it was one of the first cases where the Court extended the Fourteenth Amendment to include a protection of the substance of the First Amendment, in this case symbolic speech or "expressive conduct", from state infringement.

Criminal law in the Waite Court: 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).

Criminal law in the Marshall Court: 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).
