Equality Texas, the state's largest gay advocate, has blasted a Texas ruling that declares the state's gay marriage ban constitutional.

The ruling issued Tuesday by the Fifth Texas Court of Appeals overturns a lower court's decision that allowed a gay couple to divorce and found the state's ban on gay marriage in violation of the U.S. Constitution.

District Judge Tena Callahan's ruling allowed two Dallas men, known only as J.B. and H.B., married in Massachusetts to divorce. But Texas Attorney General Greg Abbot, a Republican, intervened in the case, arguing that the marriage should be “voided,” which essentially nullifies the marriage as invalid.

“The court's view of same-sex relationships is uninformed, outdated and homophobic – predicating its decision upon the ability to have children naturally – thereby ignoring the thousands of Texas households raising kids with same-sex parents or even single parent households,” the group said in a statement first reported by gay weekly The Dallas Voice.

Plaintiffs' lawyers have not announced whether they'll appeal, but, according to Texas Equality, the all-Republican 3-judge panel's ruling sets a high barrier to overcome.

The court “has taken the most extreme, the most conservative view possible on each issue before it. It's not as if they wanted to just overturn the trial court's decision, they wanted to smash it into the ground and discourage anyone from ever filing a pro-LGBT suit ever again.”

“The gay divorce ruling reads like an anti-thesis to U.S. District Judge Vaughn Walker's decision last month,” Voice reporter John Wright wrote, referring to Walker's ruling that struck down California's gay marriage ban, Proposition 8, as unconstitutional.

The men married in Massachusetts – the first U.S. state to legalize gay marriage in 2004 – in September 2006. J.B. said the couple had been together 11 years and that the split was painful but amicable. He filed for divorce in January 2009, citing “discord of conflict of personalities.”
