Tamaulipas voted to legalise same-sex marriage on 26 October, becoming the final of Mexico’s 32 states to do so.
The measure was passed with 23 votes in favour to 12 against and two abstenations, meaning the state’s Civil Code will be amended.
“Today is a historic day for the LGBTQ community and for Mexico,” said LGBTQ+ activist Enrique Torre Molina. “Today we and our families are more visible, more equal, and we are a country with more justice.”
Andrea Chávez, federal deputy of Ciudad Juárez in Chihuahua, added: “One more step in achieving a more just, dignified and equal life for all people… love is love!”
It comes in the same month that three other states approved the changes, with lawmakers in Guerrero doing so just a day earlier.
Preventing same-sex marriage was deemed unconstituional by the Supreme Court in 2015, though some states hve taken several years to conform with the ruling.
“The whole country shines with a huge rainbow. Live the dignity and rights of all people. Love is love,” said Arturo Zaldívar, the president of the Supreme Court of Justice of the Nation, shortly after the vote in Tamaulipas.
