Same-sex marriage has been legal in Tlaxcala since 25 December 2020. Legislation to legalise same-sex marriage passed the Congress of Tlaxcala on 8 December 2020 by a vote of 16âÂÂ3, and came into force on 25 December following Governor Marco Antonio Mena RodrÃÂguez's signature. Tlaxcala was the 19th Mexican state to open marriage to same-sex couples. The state has also recognised civil unions, which grant several of the rights and benefits of marriage, for both opposite-sex and same-sex couples since 12 January 2017.
The Supreme Court of Justice of the Nation ruled on 12 June 2015 that state bans on same-sex marriage are unconstitutional nationwide. The court's ruling is considered a "jurisprudential thesis" and did not invalidate state laws, meaning that same-sex couples denied the right to marry would still have to seek individual amparos in court. The ruling standardized the procedures for judges and courts throughout Mexico to approve all applications for same-sex marriages and made the approval mandatory. Specifically, the court ruled that bans on same-sex marriage violate Articles 1 and 4 of the Constitution of Mexico. Article 1 of the Constitution states:
In late June 2015, fifteen same-sex couples applied for marriage licenses at the civil registry office in Tlaxcala, but all were rejected. With the help of the State Human Rights Commission, they filed individual in court. On 27 November 2015, a federal court granted an to one of the couples. Their marriage, which was the first same-sex marriage in Tlaxcala, took place on 18 January 2016 in Ixtenco. The was only granted after the Commission had interceded on their behalf.
In February 2014, Deputy Eréndira Montiel Jiménez from the Party of the Democratic Revolution (PRD) promised to introduce a partnership bill to the Congress of Tlaxcala. The proposed legislation, introduced on 3 April 2014, outlined the legal framework for a form of coexistence "that [had] the purpose of marriage or concubinage". On 29 December 2016, Congress approved the coexistence bill by 18 votes to 4. Two deputies from the National Action Party (PAN) walked out in protest as the voting took place. The bill established an institution called (), which provides cohabiting same-sex and opposite-sex couples with many of the rights and obligations of marriage. The law was published in the official state journal on 11 January 2017, following Governor Marco Antonio Mena RodrÃÂguez's signature, and took effect the following day.
A bill to legalize same-sex marriage was first presented to the Congress of Tlaxcala on 2 October 2009. The proposal was blocked by state lawmakers in 2010, and the state, along with officials from Guanajuato, Jalisco, Morelos and Sonora, later filed a formal court challenge to the passage of a same-sex marriage law in Mexico City. In June 2011, activists questioned why no action had been taken on the bill and were told that it was still "climbing the roster". Deputy MarÃÂa Stankiewicz RamÃÂrez from the Institutional Revolutionary Party (PRI) announced that a same-sex marriage bill would be debated in a Congress committee sometime in July 2016, though no vote happened. On 13 October 2017, the New Alliance Party introduced a new bill to Congress.
The July 2018 elections resulted in the National Regeneration Movement (MORENA) and the Labor Party (PT), which support the legalization of same-sex marriage, winning the majority of legislative seats in Congress. In October 2018, Deputy Miguel Covarrubias Cervantes from the Party of the Democratic Revolution introduced a same-sex marriage bill to Congress. The legislation was approved by a 16âÂÂ3 vote on 8 December 2020. It was published in the official state journal on 24 December, following the signature of Governor Mena RodrÃÂguez, and took effect the following day. The law amended article 42 of the Civil Code to read: Marriage is the union of two persons with their full consent, whose purpose is to establish a shared life, in which both partners provide each other with respect, equality, and mutual support. It must be entered into before the officials designated by law and with all the formalities required by it.
