We won a major court victory for LGBT equality on Thursday. A federal judge in Massachusetts ruled that part of the notorious "Defense of Marriage Act" -- which blocks the federal government from recognizing same-sex marriage -- is unconstitutional.

This ruling is wonderful news and a huge victory in our fight to bring full equality to all Americans. But the federal government can appeal the ruling. It's time to organize to ask our president to uphold equality by letting this decision stand.

Please join us in asking President Obama to direct the Justice Department to stand down and not appeal this ruling:

President Obama:

We, the undersigned, urge you to respect the federal judge's decision ruling parts of the "Defense of Marriage Act" to be unconstitutional by directing the agencies under your control to not appeal this ruling.

This historic decision by Judge Joseph Tauro makes it clear that the "Defense of Marriage Act" was motivated by what he called "irrational prejudice." There is no justification for continuing to defend this unconstitutional law in the courts.

We look to you to provide national leadership in support of full equality for all Americans. Please join us in welcoming this historic verdict by pledging to not appeal it to a higher court.

Sincerely,
