The organizers behind the lawsuit challenging California’s Proposition 8 are excited and optimistic about the prospects for a Supreme Court ruling against the anti-gay measure as one attorney on the team said he hopes the Obama administration will assist in the effort.

Ted Olson, a co-counsel in the Prop 8 lawsuit, made the remarks during a conference call on Friday in response to a question from Politico’s Josh Gerstein. Olson said a friend-of-the-court brief from the Justice Department would have “great effect” in the effort to overturn Prop 8.

“I would hate to predict what the United States government is doing, but given the stand the president of the United States and the attorney general of the United States made with respect to marriage equality, we would certainly hope that they would participate,” Olson said. “And I’m quite confident that if they did participate, they would support our position in this case because the denial of equal rights is subject to close scrutiny by the courts and cannot withstand that scrutiny.”

Olson said if the Obama administration were to file a brief before the Supreme Court in the Prop 8 case, it would do so at about the same time it would file a brief in the DOMA case. The Justice Department has already filed briefs against DOMA in lower courts.

The Obama administration has thus far stayed out of the Prop 8 case. Asked in September by the Washington Blade whether the U.S. government would weigh in, White House Press Secretary Jay Carney had no comment and Nanda Chitre, a spokesperson for the Justice Department, said, “We are not a party to this litigation and would decline further comment.”

That might change now that the Supreme Court has taken up the case. Like other interested parties, the Justice Department will have an opportunity to file a friend-of-the-court brief in the upcoming days as the court accepts other briefs in the lawsuit.

The organization behind the lawsuit, the American Foundation for Equal Rights, held the conference call in the wake of the Supreme Court’s decision to take up the Prop 8 case as well as one of the cases against the Defense of Marriage Act known as Windsor v. United States.

Olson was confident about a positive outcome for same-sex couples, saying the denial of their marriage rights will receive significant attention simply by being before the Supreme Court.

“We have an exhaustive record on which to build this case, and it will be an education for the American people,” Olson said. “We are very confident the outcome of this case will be to support the rights of our gay and lesbian brothers and sisters.”

David Boies, co-counsel in the lawsuit, said the decision of the Supreme Court to take up the case means only a short time remains before a final resolution is reached in the Prop 8 case.

“We are now literally within months of getting a final resolution of this case that began three-and-a-half years ago,” Boies said. “I think we are encouraged and excited about the prospect that we will finally get a decision on the merits with respect to marriage equality. This is a momentous case; I think the attention that it has already received by the Supreme Court indicates their recognition of the importance of this issue.”

Human Rights Campaign President Chad Griffin, who co-founded AFER, also expressed excitement about the prospects of a victory at the Supreme Court on the conference call.

“Today is nothing short of a milestone moment, quite frankly, for equality,” Griffin said. “We are gratified that the court has taken this challenge to Prop 8. We should also mention the challenge to the ridiculously named Defense of Marriage Act. Millions of loving couples — married and unmarried — have been waiting for their day in court, and now they’re finally going to have it.”

Also taking part in the conference call were the two plaintiff couples in the case: Kris Perry and Sandy Stier, who tried to obtain a marriage license in Alameda County, as well as Jeff Zarrillo and Paul Katami, who tried to obtain a marriage license in Los Angeles.

Had the Supreme Court decided not to take up Prop 8, a U.S. Ninth Circuit Court of Appeals ruling against the measure would have been allowed to stand and same-sex marriage would have returned to California.

But plaintiffs in the case didn’t express disappointment. Asked whether she’s unhappy the Supreme Court took up the case, Perry replied, “You may find this a little surprising: the answer is ‘no’.”

“We’ve always been very patient and understanding of this process,” Perry said. “We always wanted the biggest, boldest outcome possible, and that can only happen if the Supreme Court listens to the case.”

Stier echoed those remarks, saying she feels “zero disappointment,” but instead hope that areas affected by discrimination other than in California will obtain relief as a result of the case.

Also during the conference call, Olson and Boies answered questions about the the Supreme Court’s request for additional briefings on whether opponents of Prop 8 have standing to defend the law in court. California state officials aren’t defending the law in court, and anti-gay groups have taken up defense of the anti-gay measure instead.

Olson said that question may present an opportunity for the Supreme Court to strike down Prop 8 on the grounds that anti-gay groups can’t defend the law in court as opposed to deciding the case on the merits. Such a ruling would abrogate a ruling against Prop 8 from the Ninth Circuit that allowed anti-gay groups and let stand a district court ruling against the measure.

“If the court were to decide this on standing as far as the Perry case is concerned, that would reinstate the 134-page opinion from District Judge Vaughn Walker, which decided all of the issues comprehensively in favor of the constitutional rights of marriage equality,” Olson said.

Asked by Buzzfeed’s Chris Geidner whether attorneys would actively argue that proponents of Prop 8 don’t have standing in court, Boies said that would indeed be the case.

“We will be making the standing argument,” Boies said. “We think the standing argument is strongly supported by existing Supreme Court precedent.”

The Prop 8 attorneys had previously filed a brief with the Supreme Court asking justices not to hear the case, but Olson said during the conference call his team has maintained at the same time that the lawsuit would be “the perfect vehicle” for deciding the right to marriage equality throughout the country.

“Gay and lesbians and all citizens have the right to have this issue … before the court with a fully developed record, with evidence on history, the importance of marriage, the damage done by discrimination and the fact that all Americans will benefit by the fact that people will be treated equally throughout this country to marry the person that they love,” Olson said.

In response to a question from The Huffington Post’s Sam Stein on whether opponents of Prop 8 would be better off if a ruling against DOMA came first, Olson denied sequencing would be a problem, saying, “We have never agreed with those concerns.”

“In short, the record is so complete that we have always felt that if the issue of marriage equality was going to be before the Supreme Court, the Proposition 8 Perry case should be a part of it because it has vastly more developed evidentiary record and specific thoughtful findings by a district judge who listened to all the evidence, and there was no evidence of any persuasive effect on the other side,” Olson said.

The opportunity for the court to hear the Prop 8 lawsuit means the Supreme Court may make a national ruling on same-sex marriage that affects not just California, but every state in the country with a ban on same-sex marriage.

Asked by The Advocate’s Julie Bolcer about scenarios in which a Supreme Court ruling might have an impact outside California, Boies said may justices may issue a ruling with larger reach depending on the way they examine the case.

Boies said if the Supreme Court addresses in its ruling the “fundamental merit” issue of whether discrimination against gays and lesbians is unconstitutional under the U.S. Constitution, that ruling would mean “there would be a fundamental right to marry in every state in the country because obviously the federal Constitution applies to every state in the country.”

Still, Boies said the ruling would be limited to California if justices decide the case on same narrow ground as the Ninth Circuit or simply determine that proponents of Prop 8 don’t have standing to defend the law in court. Even so, Boies said such rulings would establish precedent that would have an impact on other marriage cases throughout the country.
