NEW YORK (AP) – A judge has thrown out the first direct legal challenge to New York Gov. David Paterson’s move to recognize out-of-state same-sex marriages, calling the policy a legally allowable stand for fairness.

The decision by same-sex couples to wed represents “a personal expression of emotional devotion, support and interdependence and a public commitment,” Bronx state Supreme Court Judge Lucy Billings wrote in a decision issued Sept. 2. “With that validity, they expect equal treatment with other married couples.”

Thousands of gay and lesbian New Yorkers over the next few years are expected to make use of Massachusetts’ recent decision to let out-of-state same-sex couples marry there. The Christian legal organization that brought the New York case said it would appeal, while gay-rights and civil-liberties groups hailed the ruling as buttressing legal support for same-sex couples.

In a statement, Paterson called it “a wise and fair determination.”

Same-sex couples cannot marry in New York, and the state’s highest court has said only the Legislature has the authority to change that. But Paterson’s counsel told state agencies in May that a recent state appellate court ruling required them to recognize same-sex marriages legally performed elsewhere or risk discrimination claims.

The directive prompted a lawsuit from the Alliance Defense Fund, a Christian legal group that has repeatedly challenged attempts to extend spousal rights to same-sex couples in New York.

The alliance is involved in numerous cases around the country that concern same-sex marriage, abortion, school prayer and other social issues. It already had several ongoing cases over attempts to extend spousal rights to same-sex couples in New York.

Several Republican state senators signed onto the latest suit.

Attorneys for the Scottsdale, Arizona-based alliance have said it opposes same-sex marriage in general, but the group’s case against Paterson focused on what it saw as overstepping his constitutional authority.

The alliance argued that recognizing out-of-state same-sex marriages was up to the state Legislature, not the governor, and legislators hadn’t moved toward such recognition.

The Democratic governor’s lawyers noted that lawmakers hadn’t expressly barred it, either, despite several proposals.

The judge agreed, calling the policy a “permissible, if not mandated, step toward the objective of equality for a group for whom legal as well as practical barriers to equality persist.” She also said refusing to respect a same-sex marriage conducted elsewhere is “antithetical to family stability.”

Alliance Defense Fund lawyer Jim Campbell said the judge’s decision made New York subject to other states’ choices on same-sex marriage. He challenged her holding that New York’s Legislature had “conspicuously” declined to act on honoring out-of-state same-sex weddings.

“If you define marriage for yourself and something from somewhere else conflicts with your definition of marriage, it’s redundant and unnecessary to declare that you’re not going to recognize that out-of-state (policy),” he said.

Lambda Legal, a gay rights group that entered the case on behalf of two female state employees who married in Canada, said the judge’s decision amplified “a steady drumbeat of courts recognizing long-standing New York law as it applies to same-sex couples.”
