WASHINGTON, Dec 3 (Reuters) - The U.S. Supreme Court on Monday remained silent about whether it will enter the legal fray over same-sex marriage a n d hear one of several pending appeals on the issue.

The court's nine justices met in private on Friday to consider whether to review challenges to the U.S. Defense of Marriage Act, which denies federal benefits to married same-sex couples, and to California's gay marriage ban, known as Proposition 8.

In an "orders list" issued early on Monday, the court made no mention of any of the same-sex marriage cases. Instead, it relisted those cases for further consideration at its weekly conference this Friday. The justices sometimes hold especially complex cases for a future conference if they want more time to consider a course of action.

Thirty-one of the 50 states have passed constitutional amendments banning gay marriage while Washington, D.C., and nine states have legalized it, three of them in November elections.

At issue is the 1996 Defense of Marriage Act, or DOMA, which only recognizes marriages between a man and a woman. Gay men and lesbians have challenged a part of the law that prevents them from receiving federal benefits that heterosexual couples receive.

Even in states where same-sex marriage is legal, the couples do not qualify for a host of federal benefits because of DOMA.

The court also is considering whether to review a challenge to California's ban on same-sex marriage. The California case, Hollingsworth v. Perry, had sought marriage equality for gays and lesbians under the U.S. Constitution.

The 9th Circuit Court of Appeals in February found the California gay marriage ban unconstitutional but it ruled narrowly in a way that only affected the one state and not the rest of the country, finding that the state could not take away the right to same-sex marriage after previously allowing it.

The justices meet at regular weekly sessions to decide which cases to add to their calendar. They vote in order of seniority, and while it takes five of the nine for a majority decision in a dispute, it takes only four votes to add a case to the agenda and schedule oral arguments.

    "This is a major turning point in the history of American civil rights," said New York City mayor Michael Bloomberg. "No American president has ever supported a major expansion of civil rights that has not ultimately been adopted by the American people - and I have no doubt that this will be no exception. The march of freedom that has sustained our country since the Revolution of 1776 continues, and no matter what setbacks may occur in a given state, freedom will triumph over fear and equality will prevail over exclusion. Today's announcement is a testament to the President's convictions, and it builds on the courageous stands that so many Americans have taken over the years on behalf of equal rights for gay and lesbian Americans, stretching back to the Stonewall Inn in Greenwich Village."

    "I applaud President Obama for announcing his support for marriage equality today," said Rep. Jerrold Nadler (D-N.Y.) "For the first time in this nation's history, a sitting president has shown the courage and leadership to stand up for all American families by pledging to support the fundamental right of every person to marry the person they love, and to have that marriage fully respected. I commend President Obama for this brave and honest step. Those who seek to politicize civil rights for personal or political gain will certainly attack him, but the course toward marriage equality and justice is the correct and inevitable path."

Obama, Pelosi and the Democrats have been a complete failure on economic issues so now they are going to focus on issues that will rile up their base.

Marriage equality is one of the most significant civil rights battles of our time and is critical to guaranteeing the equal protection under the law promised to every American in the Constitution. The President's support for marriage equality should inspire Congress, Governors and state legislatures to advance civil rights for all Americans."
