The Mexican supreme court has upheld a law legalizing same-sex marriage in Mexico City.
The court ruled Thursday that the law is constitutional, rejecting an appeal by federal prosecutors, who argued that it violated mandates to protect the family.
The justices still need to determine the 8-2 ruling's impact outside the capital city. The court also still has to rule on the constitutionality of another portion of the law, allowing adoption by gay couples in Mexico City.
In their decision, justices stressed that while the national constitution provides for the protection of families, it does not define what makes a family.
