The ACLU has issued their official, cautious statement regarding today's ruling, which they caution "is not the end."
“Today’s decision is a huge victory for the LGBT people of America. For the first time, a federal court has conducted a trial and found that there is absolutely no reason to deny same-sex couples the fairness and dignity of marriage,” said James Esseks, Director of the ACLU Lesbian, Gay, Bisexual and Transgender Project. “At the same time, we know that this is not the end. In order to give this case the best possible chance of success as it moves through the appeals courts, we need to show that America is ready for same-sex couples to marry by continuing to seek marriage and other relationship protections in states across the country. It’s simply not fair, and not legal, to continue to exclude committed same-sex couples from marriage.”
They add that, despite this national-headline drama, they're still working to pass marriage bills in New York, Rhode Island and Maine and seeking domestic partnership recognition in Montana, Hawaii, Illinois, New Mexico, and Alaska. You'll recall that the ACLU and two other gay legal advocacy groups tried to become parties in the suit against the state, and weren't entirely excited about the push by the suit's backers to bring this case swiftly to the Supreme Court.
