California Gov. Arnold Schwarzenegger says he hopes the state's highest court will overturn Proposition 8, passed by voters last week to define marriage as being only between a man and a woman.
He also predicted the 18,000 gay and lesbian couples who were already married before the initiative passed would not be affected.
Prop 8 opponents continue to protest. Schwarzenegger is telling them "not to give up."

On Monday, the Christian legal group Liberty Counsel stepped in to help defend the new amendment against three lawsuits filed at the state's Supreme Court. The suits, filed by same-sex marriage supporters, are asking the Court to overturn the Prop 8.
"The proponents of same-sex marriage have thrown a 'Hail Mary' pass with no receivers down field," Libery Counsel Founder Mathew D. Staver said. "The people have a right to amend their constitution. It is amazing how much effort has been put in this battle to keep the people from deciding the future of marriage."
"It makes no sense that four judges can re-write the historic definition of marriage and more than five million people cannot restore it to its common understanding as the union of one man and one woman," Staver said.
The lawsuits were filed by the American Civil Liberties Union, the National Center for Lesbian Rights, Lambda Legal, Santa Clara County, the city of San Francisco, the city of Los Angeles, and Los Angeles lawyer Gloria Allred, on behalf of a lesbian couple.
Over the weekend, gay marriage supporters took their protests to the streets of San Diego and Los Angeles. The protest parade in San Diego had close to 10,000 marchers and lasted almost four hours.
"We want people to know that we're not going away," said marcher Donna Sievers. "We're going keep fighting this issue and we will win. It may take a little bit of time but we're going to win."
Supporters of the new initiative also showed up at Sunday's protest.
"It seems like many people do not want to accept what the results are, so what I am doing is I'm demonstrating how they are acting by holding these pacifiers and baby food," said Prop 8 supporter Mark Baldwin.
In a CNN interview broadcast Monday, Schwarzenegger said it's "not the end" of the controversy over Proposition 8.
"It's unfortunate, obviously, but it's not the end," Schwarzenegger said during the interview. "I think that we will again maybe undo that, if the court is willing to do that, and then move forward from there and again lead in that area."
A repeal vote could come up in 2010, while Schwarzenegger is still governor.
Meanwhile, demonstrators gathered in Chicago saturday night to protest Dr. James Dobson's induction into the Radio Hall of Fame.
Protesters shouted for "equal rights," while others held signs that read "Dobson Discriminates." Others labeled him a "bigot."
Dobson supported passage of California's Prop 8 and often speaks out against gay marriage on his "Focus on the Family" radio program.
But the Radio Hall of Fame says it doesn't take a nominee's political or religious views into consideration.
