In response to the New Mexico Supreme Court legalizing gay marriage in the state, Brian Brown, president of the National Organization for Marriage (NOM), reiterated the need for an amendment to the U.S. Constitution defining marriage as a heterosexual union.

“Today's opinion by the New Mexico Supreme Court is disappointing but not surprising,” Brown wrote in a blog post. “These are the same justices that demanded in an earlier ruling that Christians be the ones to compromise and deny their faith, in the case of Elane Photography. Once again, activist judges have thrown out the historic legal understanding of marriage in New Mexico. This is a continuation of a very dangerous rush towards silencing people of faith who simply believe marriage to be the union of one man and one woman. The National Organization for Marriage will do everything in its power to protect believers of true marriage in New Mexico and around the nation from the fallout of radical judges who deny the truth of marriage.”

Brown went on to urge Congress to approve the Federal Marriage Amendment introduced by Kansas Rep. Tim Huelskamp, a Republican, in reaction to the Supreme Court striking down a key provision of the Defense of Marriage Act (DOMA), which led to the federal government recognizing the legal marriages of gay couples.

The New Mexico ruling came less than a month after Brown predicted victories for opponents of marriage equality.
