House Minority Leader Nancy Pelosi, New York Congressman Jerrold Nadler and 130 House Democrats have filed an amicus brief against the Defense of Marriage Act (DOMA).

The brief was filed in support of Karen Golinski, a federal employee who sued the Office of Personnel Management (OPM) and won health-care coverage for her wife, Amy Cunninghis. OPM argued that DOMA blocked such coverage.

The House's Bipartisan Legal Advisory Group (BLAG) at the direction of House Speaker John Boehner intervened to defend the law after President Barack Obama instructed the Department of Justice to no longer defend DOMA in court.

While the BLAG lawyers have appealed the decision, which found DOMA to be unconstitutional, they have yet to request a stay of the court's ruling pending an appeal.

Last week, the White House asked the Supreme Court to review the case.

In a statement, House Democrats said their brief “makes it clear that the House is not united on DOMA's validity, that the BLAG lawyers do not speak for the entire institution, and that there is no legitimate federal interest in denying married same-sex couples the legal security, rights and responsibilities that federal law provides to couples who are married under state law. Section 3 does not affect married heterosexual couples and their children, who are recognized regardless of DOMA. And this law affirmatively harms married gay and lesbian couples and their children.”

The brief's sponsors have pledged to file an amicus brief in each of the cases where the BLAG has intervened.
