Brian Brown, president of the National Organization for Marriage (NOM), on Wednesday condemned two Supreme Court rulings related to gay marriage.

The high court declared that the Defense of Marriage Act (DOMA), which prohibits the federal government from recognizing the legal marriages of gay and lesbian couples, violates the Fifth Amendment rights of gay couples. In a separate decision, the court dismissed an appeal to a lower court's ruling invalidating Proposition 8, California's 2008 voter-approved constitutional amendment defining marriage as a heterosexual union. The ruling, authored by Chief Justice John Roberts, determined that the Prop 8 petitioners had no standing to appeal.

Brown, who on Tuesday predicted victory in “Roe decision for marriage,” called the rulings a “miscarriage of justice.”

“The Supreme Court's holding that proponents of an initiative had no legal right to appeal ignores California law and rewards corrupt politicians for abandoning their duty to defend traditional marriage laws,” Brown said in a statement, referring to the Prop 8 case.

“There is a stench coming from this case that has now stained the Supreme Court. They've allowed corrupt politicians and judges to betray the voters, rewarding them for their betrayal. It's an illegitimate decision.”

Brown went on to call on Americans to reject the court's ruling on Prop 8: “We and millions of other Americans will refuse to accept this rogue decision rewarding corruption.”

“We also urge Congress to reject the inevitable attempts to dismantle remaining elements of DOMA, including the right of states to refuse to recognize so-called gay marriages performed elsewhere.”

The saving grace, he added, was that the court had “refused to go along with the urgings of [lawyers for the plaintiffs] Ted Olson and David Boies to find a constitutional right to same-sex 'marriage.'”

“The plaintiffs failed in their primary objective, which is a major victory for those defending Proposition 8, especially Chuck Cooper and his firm, along with the attorneys at the Alliance Defending Freedom, and Andy Pugno of the Prop 8 Legal Defense Fund.”

Standing on the steps of the Supreme Court, Olson saw things differently.

“The Supreme Court held that the proponents of Proposition 8 did not have standing,” Olson told reporters. “What that means is that in that case the Supreme Court could not reach the merits. But everything that the Supreme Court said in the Defense of Marriage opinion, where they did reach the merits, demonstrates that when that case finally does come to the United States Supreme Court on the merits, marriage equality will be the law throughout this land.”

Today's decisions are the ninth and tenth defeats for Brown in recent months. At the polls in November, voters in two states – Washington and Maryland – upheld marriage laws approved by lawmakers, and in Minnesota, voters for the first time rejected a constitutional amendment defining marriage as a heterosexual union. A marriage law was approved for the first time at the ballot box in Maine. And Iowa voters decided against ousting a state Supreme Court judge for his participation in the 2009 unanimous ruling which brought marriage equality to the Midwest. Lawmakers in three additional states – Delaware, Minnesota and Rhode Island – in recent months also approved bills allowing same-sex couples to marry.

In all those cases, Brown had confidently predicted a win for his side.

California will become the 13th state, plus the District of Colombia, where gay couples can legally marry – encompassing nearly one-third of the nation's population.
