Question: Which landmark civil rights decision of the United States Supreme Court involved the issue of interracial marriage that used the Latin phrase " Et uxor?"

full_context: Document 1: Married Women's Property Act 1893: The Married Women's Property Act 1893 was an Act of the Parliament of the United Kingdom that significantly altered English law regarding the property rights granted to married women. It completed the Married Women's Property Act 1882 by granting married women the same property rights equal to unmarried women.
Document 2: Loving (2016 film): Loving is a 2016 British-American historical drama film which tells the story of Richard and Mildred Loving, the plaintiffs in the 1967 U.S. Supreme Court decision "Loving v. Virginia", which invalidated state laws prohibiting interracial marriage. The film was produced by Big Beach and Raindog Films, and distributed by Focus Features. The film takes inspiration from "The Loving Story" (2011) by Nancy Buirski, a documentary which follows the Lovings and their landmark case.
Document 3: Ex rel.: Ex rel. is an abbreviation of the Latin phrase ""ex relatione" (meaning "[arising] out of the relation/narration [of the relator]" ). The term is a legal phrase; the legal citation guide, the "Bluebook", describes "ex rel." as a "procedural phrase" and requires using it to abbreviate "on the relation of", "for the use of", "on behalf of", and similar expressions.
Document 4: Anti-miscegenation laws: Anti-miscegenation laws or miscegenation laws were laws that enforced racial segregation at the level of marriage and intimate relationships by criminalizing interracial marriage and sometimes also sex between members of different races. Such laws were first introduced in North America from the late seventeenth century onwards by several of the Thirteen Colonies, and subsequently by many US states and US territories and remained in force in many US states until 1967. After the Second World War, an increasing number of states repealed their anti-miscegenation laws. In 1967, in "Loving v. Virginia", the remaining anti-miscegenation laws were held to be unconstitutional by the Supreme Court of the United States. Similar laws were also enforced in Nazi Germany as part of the Nuremberg laws, and in South Africa as part of the system of Apartheid.
Document 5: Loving Day: Loving Day is an annual celebration held on June 12, the anniversary of the 1967 United States Supreme Court decision "Loving v. Virginia" which struck down all anti-miscegenation laws remaining in sixteen U.S. states." In the United States, anti-miscegenation laws were U.S. state laws banning interracial marriage, mainly forbidding marriage between non-whites and whites.
Document 6: Maiden and married names: When a person (traditionally the wife in many cultures) assumes the family name of his or her spouse, that name replaces the person's birth surname, which in the case of the wife is called the maiden name (birth name is also used as a gender-neutral or masculine substitute for maiden name), whereas a married name is a family name or surname adopted by a person upon marriage.
Document 7: Obergefell v. Hodges: Obergefell v. Hodges, 576 U.S. ___ (2015) ( ), is a landmark civil rights case in which the United States Supreme Court ruled that the fundamental right to marry is guaranteed to same-sex couples by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution in a 5–4 decision.
Document 8: Interracial marriage in the United States: Interracial marriage in the United States has been fully legal in all U.S. states since the 1967 Supreme Court decision that deemed anti-miscegenation laws unconstitutional, with many states choosing to legalize interracial marriage at earlier dates. Multiracial Americans numbered 9.0 million in 2010, or 2.9% of the total population, but 5.6% of the population under age 18. The actual number is likely much higher, for example a study of college students identifying as white found that 30% had less than 90% European ancestry, and one recent study found that African Americans have an average of 21% European ancestry.
Document 9: Turkish name: A Turkish name consists of an "ad" or an "isim" (given name; plural "adlar" and "isimler") and a "soyadı" or "soyisim" (surname). Turkish names exist in a "full name" format. While there is only one "soyadı" (surname) in the full name there may be more than one "ad" (given name). Married women may carry both their maiden and husband's surnames. The "soyadı" is written as the last element of the full name, after all given names (except that official documents often use the format "Soyadı, Adı").
Document 10: Loving v. Virginia: Loving v. Virginia, 388 U.S. 1 (1967) is a landmark civil rights decision of the United States Supreme Court, which invalidated laws prohibiting interracial marriage.
Document 11: Et uxor: Et uxor is a Latin phrase meaning "and wife", commonly abbreviated "et ux." The term is a legal phrase that is used in lieu of naming the female spouse of a male party to litigation, for example "Loving et ux. v. Virginia". The term remains in contemporary use in American legal documents, especially as related to property and marriage. Many older property deeds list the owners in the form "John Smith "et ux."" In the present day, most jurisdictions would indicate both the husband and wife by name.
Document 12: List of current United States first spouses: In the United States, the first spouse (first lady for women, first gentleman for men) is the term used to refer to the spouse of a chief executive - that is, of the spouse of the President of the United States (the First Lady of the United States and the First Gentleman of the United States) and the spouses of the governors of the 50 U.S. states and U.S. territories (Guam, Northern Mariana Islands, Puerto Rico, American Samoa, and the United States Virgin Islands) and the spouse of the mayor of the District of Columbia. (The spouses of many mayors are often called the "first lady" or "first gentleman" of the city as well, and the use of the terms sometimes extends even to the spouses of college presidents).
Document 13: Et vir: Et vir is a Latin phrase meaning "and husband". It is used in legal literature to indicate a couple comprising an identified woman and her otherwise unidentified husband. For example, the U.S. Supreme Court case "Troxel et vir v. Granville" is an example of modern legal usage of the Latin phrase. Additionally, many property deeds would list the owners in the form "Jane Doe "et vir"" when appropriate.
Document 14: McLaughlin v. Florida: McLaughlin v. Florida, 379 U.S. 184 (1964), was a case in which the United States Supreme Court ruled unanimously that a cohabitation law of Florida, part of the state's anti-miscegenation laws, was unconstitutional. The law prohibited habitual cohabitation by two unmarried people of opposite sex, if one was black and the other was white. The decision overturned "Pace v. Alabama" (1883), which had declared such statutes constitutional. It did not overturn the related Florida statute that prohibited interracial marriage between whites and blacks. Such laws were declared unconstitutional in 1967 in "Loving v. Virginia".
Document 15: Relator (law): Relator , female relatrix , (Latin for "narrator") is the legal term meaning a private person at whose relation or on whose behalf an application for a quo warranto or mandamus is filed. The relator appears as one beneficially interested, but the action is maintained on his behalf. The relator furnishes the knowledge or facts on which an information or a proceeding in quo warranto is based. Such a proceeding is usually in the name of the state, ex rel. ("ex relatione" = "[arising] out of the narration") of the relator, and so is called an "ex rel. action".
