Brian Brown, president of the National Organization for Marriage (NOM), believes the Supreme Court will take a case challenging the constitutionality of California's gay marriage ban, Proposition 8.

“I'm confident, I'm very confident, that they will take the [Prop 8] case,” Brown said on Michelangelo Signorile's OutQ radio show.

Brown, whose group's primary purpose is opposing marriage equality, said he was also confident that his side would win.

“I don't think the court is going to find some hidden right to same-sex marriage deeply embedded in our Constitution. So, I think we're going to win,” he said.

The high court was asked by Prop 8 supporters to review the case after a federal district court in 2010 found the amendment to be unconstitutional and its ruling was upheld by the Ninth Circuit Court of Appeals.

The court's decision to take the case could come as early as Tuesday.

If the court passes on the case, then the lower court's ruling would stand. Proponents expect marriages wold resume in California within several days after the Supreme Court denies review.
