Lawmakers in California are calling on Congress to repeal the Defense of Marriage Act (DOMA).

With a 22-12 vote Monday, the California Senate joined the Assembly in approving the resolution urging Congressional leaders to overturn the gay marriage ban.

“We're proud of the California legislature for making the state's opposition to DOMA official state policy,” Geoff Kors, executive director of Equality California, the state's largest gay advocate, said. “Now we must overturn this discriminatory federal law and pave the way for the marriages of same-sex couples to be recognized at the federal level.”

The Clinton-era law defines marriage as a heterosexual union for federal agencies and allows states to ignore the legal marriages of gay couples from outside their borders.

“President Obama has called his law abhorrent in the way it denies more than 1,000 federal rights to same-sex couples,” Assemblywoman Julia Brownley, a Democrat from Santa Monica who introduced the measure, said. “Congress must act now to overturn DOMA, which is rooted in irrational and unfounded prejudice. Married same-sex couples deserve equal access to these benefits.”

The Obama administration has yet to announce whether it will appeal a federal judge's ruling that struck down portions of DOMA as unconstitutional.

Last week, U.S. District Judge Joseph Tauro suspended his ruling for 60 days while the U.S. Department of Justice decides whether it will appeal.

Tauro's ruling only affects the state of Massachusetts, but should the government appeal to a higher court with a broader jurisdiction its impact could spread.

While the president has repeatedly said he opposes DOMA, he has yet to endorse New York Congressman Jerrold Nadler's Respect for Marriage Act, a bill that seeks to repeal the law.
