Mexico’s Supreme Court has upheld a law allowing gay marriages in the capital Mexico City. The law went into effect in March following its passage last year. Mexican gay rights activist Lol Kin Castañeda praised the ruling.

Lol Kin Castañeda: “It’s a historic moment in which our rights — the rights of all citizens without differentiation because of sexual preference or orientation — are being recognized by the government, by the laws, with the same rights. So, of course, we’re very happy about this first voting, in which the right of people of the same gender to marry is recognized as completely constitutional.”

More than 300 couples have wed under the law since its passage.
