Same-sex marriage has been legal in Jalisco since a unanimous ruling by the Mexican Supreme Court on 26 January 2016 striking down the state's same-sex marriage ban as unconstitutional under Articles 1 and 4 of the Constitution of Mexico. The ruling was published in the Official Journal of the Federation on 21 April; however, some municipalities refused to marry same-sex couples until being ordered by Congress to do so on 12 May 2016. The state Congress passed a bill codifiying same-sex marriage into law on 6 April 2022.
