Tony Perkins praised a House resolution introduced Tuesday that condemns a federal judge's ruling that struck down California's gay marriage ban, Proposition 8.

The resolution was sponsored by Texas Congressman Lamar Smith. Also backing the measure are Republican representatives Michele Bachmann of Minnesota, Steve King of Iowa and John Fleming of Louisiana.

Chief U.S. District Judge Vaughn Walker's 138-page ruling delivered on Wednesday declares Proposition 8 to be unconstitutional.

“I applaud Rep. Smith for introducing a resolution that condemns Judge Walker's flawed decision and urges its appeal,” Perkins, president of the social conservative group Family Research Council, said. “As the resolution points out, Judge Walker is a single judge who thinks he knows better than seven million Californians and voters in more than 30 states who have approved marriage amendments.”

“I thank Congressman Lamar Smith and his colleagues for introducing this resolution that counters Judge Walker's notion that a child doesn't deserve a mother and a father.”

Perkins also reiterated his “social science” argument first leveled on Sunday while debating David Boies, a member of the legal team that challenged the law, on CBS' Face the Nation.

In the segment, Perkins said Walker “ignored a lot of the social science in his opinion.”

Boies disagreed, and called such evidence “junk science.”

“Well, it's easy to sit around and debate and throw around opinions – appeal to people's fear and prejudice, cite studies that either don't exist or don't say what you say they do.”

“But when they come into court and they have to support those opinions and they have to defend those opinions under oath and cross-examination, those opinions just melt away. And that's what happened here. There simply wasn't any evidence. There weren't any of those studies. There weren't any empirical studies. That's just made up. That's junk science.”

The House resolution is mostly symbolic and not expected come up for a vote.
