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.
The U.S. Supreme Court's ruling in "Obergefell v. Hodges" on June 26, 2015, held that the denial of marriage rights to same-sex couples is unconstitutional, invalidating the ban on same-sex marriage in Louisiana.
 The ruling clarified conflicting court rulings on whether Louisianian officials are obligated to license same-sex marriages. Governor Bobby Jindal confirmed on June 28 that Louisiana would comply with the ruling once the Fifth Circuit Court of Appeals reversed its decision in a Louisiana case, which the Fifth Circuit did on July 1.
 Jindal then said the state would not comply with the ruling until the federal District Court reversed its judgment, which it did on July 2.
 All parishes now issue marriage licenses in accordance with federal law.
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.
Timothy E. Quill is an American physician specialising in palliative care at the University of Rochester Medical Center in Rochester, New York.
 He is also a board member of the Death with Dignity National Center in Portland, Oregon.
 Quill was the lead plaintiff in a case that eventually reached the Supreme Court of the United States in 1997, "Vacco v. Quill", in which the Court decided that a state law against physician-assisted suicide was constitutional.
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 has been legally recognized in the U.S. state of Indiana since October 6, 2014.
 The state had previously restricted marriage to male-female couples by statute in 1986.
 By legislation passed in 1997, it denied recognition to same-sex relationships established in other jurisdictions.
 A lawsuit challenging the state's refusal to grant marriage licenses to same-sex couples, "Baskin v. Bogan", won a favorable ruling from the U.S. District Court for the Southern District of Indiana on June 25, 2014.
 Until the U.S. Court of Appeals for the Seventh Circuit granted an emergency stay of the district court's ruling on June 27, most Indiana counties issued marriage licenses to same-sex couples.
 The Court of Appeals affirmed the district court's ruling in "Baskin" on September 4.
 A ruling in "Bowling v. Pence" stated that the state must recognize same-sex marriages performed out-of-state and the decision was stayed until the Circuit ruled on the merits in similar cases.
 It also stated that the ruling would remain stayed if the circuit court stayed its decision in the related cases.
The Louisiana Software License Enforcement Act refers to the Software License Enforcement Act (SLEA) adopted by the state of Louisiana.
 The bill was voted into law in September 1984 under Title 51 (Trade and Commerce) of the Louisiana Revised Statutes by the Louisiana State Legislature.
 Sponsored and mostly written by Vault Corporation, the SLEA defines the permissible terms and conditions of a software license agreement and the requirements for enforceability.
 The reverse engineering, decompiling or disassembling provision of the Louisiana SLEA was invalidated by the United States Court of Appeals for the Fifth Circuit ruling in "Vault Corp. v. Quaid Software, Ltd., 847 F.2d 255 (5th Cir.
 1988)".
Vacco v. Quill, 521 U.S. 793 (1997), is a landmark decision of the Supreme Court of the United States regarding the right to die.
 It ruled 9-0 that a New York ban on physician-assisted suicide was constitutional, and preventing doctors from assisting their patients, even those terminally ill and/or in great pain, was a legitimate state interest that was well within the authority of the state to regulate.
 In brief, this decision established that, as a matter of law, there was no constitutional guarantee of a "right to die."
Montejo v. Louisiana, 556 U.S. 778 (2009), is a 5–4 decision by the United States Supreme Court that overruled the Court's decision in "Michigan v. Jackson", 475 U.S. 625 (1986) .
 The case concerned the validity of a defendant's waiver of his right to counsel during a police interrogation.
 In reversing "Jackson", the Court said such a waiver was valid.

 Quill Corporation is an office supply retailer.
 Quill had no physical presence in North Dakota (neither a sales force, nor a retail outlet), but it had a licensed computer software program that some of its North Dakota customers used for checking Quill's current inventories and placing orders directly.
 North Dakota attempted to impose a use tax on Quill, which was struck down by the Supreme Court.
