Same-sex marriage has been legal in Louisiana since the U.S. Supreme Court's ruling in Obergefell v. Hodges on June 26, 2015. The Supreme Court held that the denial of marriage rights to same-sex couples violates the U.S. Constitution, invalidating Louisiana's ban on same-sex marriage. Obergefell clarified conflicting court rulings on whether state officials were obligated to license same-sex marriages. Governor Bobby Jindal, highly critical of the Supreme Court ruling, confirmed on June 28 that Louisiana would comply once the Fifth Circuit Court of Appeals reversed a federal court decision in a Louisiana case, Robicheaux v. George, which it did on July 1. Jindal then said the state would not comply with the ruling until the U.S. District Court for the Eastern District of Louisiana reversed its judgment, which it did on July 2. All parishes now issue marriage licenses in accordance with federal law.

Louisiana had previously denied marriage rights to same-sex couples by statute since 1988 and in its State Constitution since 2004. Polling suggests that a narrow majority of Louisianans support the legal recognition of same-sex marriage, with a 2024 Public Religion Research Institute poll showing that 52% of respondents supported same-sex marriage.

Legal history Restrictions In 1988 and 1999, the Louisiana State Legislature added provisions to the Civil Code banning same-sex couples from marrying and prohibiting the recognition of same-sex marriages from other jurisdictions.La. C.C. arts. 89, 3520 During this period, the U.S. Congress also enacted the Defense of Marriage Act (DOMA; ), which banned federal recognition of same-sex marriages. The parts of DOMA that banned same-sex marriages were overturned in 2013 in United States v. Windsor, and the state statutes prohibiting same-sex marriage were likewise struck down in 2015 in Obergefell v. Hodges. Though unconstitutional and unenforceable, these statutes remain on the books. In March 2018, the Louisiana Senate Judiciary Committee rejected 1–4 a bill to repeal the statutory ban, with Senator Jay Luneau, a Democrat from Alexandria, being the sole lawmaker in favor. The bill's main sponsor, Senator Jean-Paul Morrell, said in response, "This is the law of the land whether you like it or not." The Louisiana Law Institute also supported the bill.Louisiana Senate Committee rejects use of LGBT-friendly language in marriage laws

On September 18, 2004, by 78% to 22%, state voters approved a state constitutional amendment that banned same-sex marriages and civil unions. The measure banned any other legal status "identical or substantially similar to that of marriage". There have been unsuccessful attempts to call a limited constitutional convention in an effort to remove the wording. Legislation introduced by Representative Mandie Landry to repeal the constitutional language barring same-sex marriage failed in the House Committee on Civil Law and Procedure on a mostly party-line 5–8 vote in April 2024. Had it been approved, the measure would have been placed on the ballot for approval by voters.

Lawsuits

Costanza v. Caldwell In July 2013, a state trial court dismissed a lawsuit, In Re Costanza and Brewer, brought by a lesbian couple who had married in California and sought to have their marriage recognized in order to allow Constanza to adopt Brewer's biological child. The plaintiffs appealed that dismissal because they were not allowed to amend their complaint, and on February 5, 2014, 15th Judicial District Court Judge Edward Rubin ruled in favor of the plaintiffs and authorized the adoption in a separate action.

Costanza and Brewer merged their suit that challenged Louisiana's same-sex marriage ban and their adoption case into one action. They were represented by private counsel, Lafayette attorney Joshua S. Guillory, and professor of law Paul Baier. On September 22, 2014, Judge Rubin found Louisiana's ban an unconstitutional violation of the Equal Protection, the Due Process and the Full Faith and Credit clauses of the U.S. Constitution. The ruling only applied to the state's 15th Judicial District, comprising the parishes of Lafayette, Acadia and Vermilion. State officials asked Rubin to stay his decision and announced plans to appeal directly to the Louisiana Supreme Court. Rubin ordered the state to allow the plaintiffs to file a joint state income tax return and to allow their adoption to proceed. He also enjoined the state from enforcing laws that "prohibit a person from marrying a person of the same sex".Order, Costanza v. Caldwell, March 22, 2014, accessed March 24, 2014 He stayed his ruling pending appeal, and Attorney General Buddy Caldwell appealed directly to the Louisiana Supreme Court, which heard oral arguments as Costanza v. Caldwell on January 29, 2015.

On July 7, 2015, following the U.S. Supreme Court decision in Obergefell v. Hodges on June 26, 2015, the Louisiana Supreme Court, by a 6–1 ruling, found the case moot and dismissed the state's appeal, making the district court's ruling in Costanza final and binding.

Robicheaux v. George

In July 2013, a lawsuit brought in the U.S. District Court for the Eastern District of Louisiana challenged the state's refusal to recognize same-sex marriages from other jurisdictions. The plaintiffs were a same-sex couple married in Iowa in September 2012, later joined by a second couple. The case was assigned to Judge Martin Feldman. The court dismissed the suit in November 2013 because it found that the only named defendant, Attorney General Caldwell, had taken no specific action with respect to the plaintiffs' marriages. On February 5, 2014, the Robicheaux plaintiffs, now joined by two women married in Iowa in 2013 and two men denied a marriage license in New Orleans in January 2014, refiled their suit, naming as principal defendant the Louisiana Director of Health, along with the Secretary of Revenue, with the case now styled Robicheaux v. George. Forum For Equality filed a separate suit on behalf of four couples on February 12, seeking recognition of same-sex marriages established in other jurisdictions. On March 18, Judge Feldman consolidated the two cases under the name Robicheaux v. Caldwell. Oral arguments on motions for summary judgment were held on June 25.

On September 3, Judge Feldman ruled for the defendants, writing that "Louisiana has a legitimate interest ... whether obsolete in the opinion of some, or not, in the opinion of others ... in linking children to an intact family formed by their two biological parents". He wrote that the idea of same-sex marriage was "nonexistent and even inconceivable until very recently". He described the issue as "a clash between convictions regarding the value of state decisions reached by way of the democratic process as contrasted with personal, genuine, and sincere lifestyle choices recognition." He found that nothing in United States v. Windsor or previous Fifth Circuit decisions required him to subject Louisiana's ban to "heightened scrutiny". He also ruled that "there is simply no fundamental right, historically or traditionally, to same-sex marriage." Under "rational basis review", he accepted the state's claim that its laws "serve a central state interest of linking children to an intact family formed by their biological parents" and further its interest in "safeguarding that fundamental social change ... is better cultivated through democratic consensus."Order and reasons, Robicheaux v. Caldwell, September 3, 2014, accessed September 3, 2014 He wrote:

He characterized other federal court decisions invalidating state bans on same-sex marriage as "the volley of nationally orchestrated court rulings ... [that] thus far exemplify a pageant of empathy; decisions impelled by a response of innate pathos." He also asked what the impact of a decision for the plaintiffs might foretell:

All parties asked the Fifth Circuit Court of Appeals to set an expedited briefing schedule to allow an appeal to be heard alongside a Texas case, De Leon v. Perry. The Fifth Circuit granted that request on September 25. The Fifth Circuit heard oral arguments on January 9, 2015, before Judges Patrick Higginbotham, Jerry Edwin Smith, and James E. Graves Jr. On November 20, the plaintiffs filed a petition asking the U.S. Supreme Court for a writ of certiorari before judgment, that is, to hear the case, now Robicheaux v. George, without waiting for a decision from the Fifth Circuit. The state supported that request on December 2. The Supreme Court denied that petition on January 12, 2015.

Obergefell v. Hodges

On June 26, 2015, the U.S. Supreme Court ruled in Obergefell v. Hodges that same-sex marriage bans violate the Equal Protection and Due Process clauses of the Fourteenth Amendment, legalizing same-sex marriage nationwide in the United States. The Robicheaux plaintiffs asked the Fifth Circuit to immediately reverse the district court ruling and have that court resolve the case in their favor. The same day, Attorney General Caldwell claimed that nothing in the Obergefell decision required the state to cease enforcing its same-sex marriage ban immediately. On June 28, Governor Bobby Jindal said the state would comply with the Supreme Court decision as soon as the Fifth Circuit reversed the district court ruling in Robicheaux. On July 1, the Fifth Circuit reversed the earlier ruling in Robicheaux and instructed the district court to record a judgment for the plaintiffs no later than July 17. Jindal then said the state would not recognize same-sex marriages until the district court reversed its ruling. In the district court, Judge Feldman issued a new judgment in favor of the plaintiffs on July 2.

Jindal was a vocal opponent of the Obergefell ruling. His initial reaction was to call for the disbanding of the Supreme Court, calling it "a public opinion poll instead of a judicial body". Jindal further stated, "This decision will pave the way for an all out assault against the religious freedom rights of Christians who disagree with this decision. This ruling must not be used as pretext by Washington to erode our right to religious liberty." Despite the United States being a secular state and the Establishment Clause forbidding governments from establishing or sponsoring religion, Jindal said that "[m]arriage between a man and a woman was established by God, and no earthly court can alter that." Attorney General Caldwell said he was "disappointed" with the decision and that it "[took] away a right that should have been left to the states".

Several parishes began issuing marriage licenses to same-sex couples on June 29, including Jefferson, Calcasieu, East Baton Rouge, West Feliciana, East Feliciana, Assumption, Livingston, Ascension and Tangipahoa. Celeste Autin and Alesia LeBoeuf were the first same-sex couple to marry in Louisiana in the early hours of Monday, June 29 in Jefferson Parish. A second couple, Michael Robinson and Earl Benjamin, were issued a marriage license in Gretna at around 11 a.m. that same day. On July 1, media outlets reported that Orleans Parish was still refusing to issue marriage licenses to same-sex couples. The district court ordered the state to begin licensing same-sex marriages the next day, and the state complied. However, for several more days, several parishes refused to issue marriage licenses to same-sex couples, including Jackson, LaSalle, Lincoln, Madison, Red River, St. Tammany and Webster. Those parishes began issuing licenses to all couples on July 6, 2015.Last clerk in Louisiana blocking same-sex marriage licenses has religious objection
