BOSTON — The federal law banning gay marriage is unconstitutional because it interferes with the right of a state to define the institution and therefore denies married gay couples some federal benefits, a federal judge ruled Thursday in Boston.
U.S. District Judge Joseph Tauro ruled in favor of gay couples' rights in two separate challenges to the Defense of Marriage Act, a 1996 law that the Obama administration has argued for repealing. The rulings apply to Massachusetts but could have broader implications if they're upheld on appeal.
The state had argued the law denied benefits such as Medicaid to gay married couples in Massachusetts, where same-sex unions have been legal since 2004.
Tauro agreed and said the act forces Massachusetts to discriminate against its own citizens in order to be eligible for federal funding in federal-state partnerships.

The act "plainly encroaches" upon the right of the state to determine marriage, Tauro said in his ruling on a lawsuit filed by state Attorney General Martha Coakley. In a ruling in a separate case filed by Gay & Lesbian Advocates & Defenders, Tauro ruled the act violates the equal protection clause of the U.S. Constitution.
"Congress undertook this classification for the one purpose that lies entirely outside of legislative bounds, to disadvantage a group of which it disapproves. And such a classification the Constitution clearly will not permit," Tauro wrote.
Nancy Gill, one of the plaintiffs in the lawsuit brought by GLAD, said she is "thrilled" with the rulings.
Coakley called it a "landmark decision" and "an important step toward achieving equality for all married couples in Massachusetts."
The Justice Department had argued that the federal government had the right to set eligibility requirements for federal benefits — including requiring that those benefits go only to couples in marriages between a man and a woman.
Opponents of gay marriage said they were certain the rulings would be overturned on appeal.
Andrea Lafferty, executive director of the Traditional Values Coalition, called Tauro's ruling "judicial activism" and said Tauro was a "rogue judge." Gay marriage advocates will keep pushing their agenda in the courts, she said, but noted voters consistently have rejected gay marriage at the ballot box.
