In a tremendous victory for equality, Mexico’s Supreme Court ruled on Thursday that a law in southern Oaxaca banning same-sex marriage is unconstitutional. The ruling paves the way for same-sex couples to marry in that state and, hopefully eventually all of Mexico.

The unanimous court struck the provision of the law that declares that “one of the purposes of marriage is the perpetuation of the species.” According to the court, to condition marriages to the union of one man and one woman for purposes of perpetuating the species violates principles of equality.

Much like abortion, same-sex marriage is only legally allowed in Mexico City after a 2010 law legally recognized such unions.

The news comes as the United States Supreme Court considers weighing in on the battle for marriage equality in this country. Should the Court take up a challenge to similar same-sex marriage bans here, let’s hope they come to a similar conclusion.
