WASHINGTON - The U.S. appeals court in Boston became the first appeals court to strike down as unconstitutional the federal Defense of Marriage Act, ruling Thursday that it unfairly denies equal benefits to legally married same-sex couples.
The groundbreaking ruling is a victory for gay rights advocates and the Obama administration, which had refused to defend this part of the 1996 law.
The decision sets the stage for a ruling next year by the Supreme Court on the constitutionality of the federal law that limits federal recognition of marriage to the union of a man and a woman.
The Boston-based judges stressed their decision did not establish a national right to gay marriage. That issue remains a matter for the states, they said.
But in states such as Massachusetts, where same-sex couples can legally marry, the federal government cannot deny them the right to file a joint federal tax return or to receive a survivor's benefit under the Social Security Act, the court said.
The opinion said there are more than 100,000 legally married gay and lesbian couples in the half-dozen states that have legalized same-sex marriages.
"For me, it's more just about having equality and not having a system of first- and second-class marriages," said plaintiff Jonathan Knight, a financial associate at Harvard Medical School who married Marlin Nabors in 2006. "I think we can do better, as a country, than that."
He said the law costs the couple an extra $1,000 a year because they cannot file a joint federal tax return.
