The Washington Blade reports:
The Mexican Supreme Court on Wednesday ruled the same-sex spouses of those who receive benefits under the country’s social security system must receive the same benefits as their heterosexual counterparts. El Economista, a Mexican newspaper, reported the justices in a 3-2 ruling said the Mexican Social Security Institute – Instituto Mexicano del Seguro Social in Spanish – must extend the same benefits that married heterosexual couples receive to gays and lesbians who have either tied the knot or entered into civil unions. Jose Alberto Gomez Barroso, who married his partner in Mexico City in 2012, sought legal recourse through the Mexican judicial system after officials denied his request to add his spouse as a beneficiary under the country’s social security system. A lower court last year dismissed Gomez’s case after he passed away.
Mexico is in a similar position to the US, with a number of states recognizing marriage equality as well as the Federal government. But in Mexico, if you are married in Mexico City, you are married everywhere.
