Don't forget to join us again here tomorrow, when the Supreme Court hears the second round of debate on same-sex marriage: the Defense of Marriage Act.
[Updated at 12:31 p.m. ET] Director Rob Reiner, who watched today’s oral arguments, is a vocal critic against Proposition 8. Here's what he had to say after court adjourned:
“Today is a historic day for all those who believe in freedom and equality. After more than four years of working our case through victories at the federal District and Circuit courts, we finally had an opportunity today to present our arguments in support of marriage equality for gay and lesbian Americans before the highest court in the land. This case has always been about the love shared by two individuals and about the central promise from our nation’s founding that all men are created equal and are endowed with inalienable rights, including the pursuit of happiness.
[Updated at 12:11 p.m. ET] Andrew Pugno, general counsel for ProtectMarriage.com, tells reporters outside the court that he believes both sides of the argument have agreed that it is impossible to know with certainly how society would change by redefining "a fundamental institution such as marriage.
[Updated at 12:04 p.m. ET] “Today we feel we clearly presented the winning case for marriage,” says Andrew Pugno, general counsel for ProtectMarriage.com, who is speaking with reporters now.
[Updated at 12:01 p.m. ET] Charles Cooper, lead counsel defending Proposition 8, told reporters that he couldn't sum up his argument in a couple of sentences. "We believe Proposition 8 is constitutional," he said, making a brief statement.
[Updated at 11:48 a.m. ET] Kris Perry, a plaintiff in the Prop 8 case, just spoke, saying: "In this country as children, we learn that there's a founding principle, that all men and women are created equal. … Unfortunately with the passage of Proposition 8, we learned that there are group of people in California who are not being treated equally."
"We look forward to a day when prop 8 is officially eliminated and equality is restored to the state of California."
[Updated at 11:45 a.m. ET] Republican Ted Olson and Democrat David Boies, who joined forces to argue against Prop 8, are speaking outside the courthouse now. What's important from today, Olson said, is "the American people were listening to the argument. The other side, nobody really offered a defense."
"We're very gratified they listened, they heard, they asked hard questions, (but) there is no denying where the right is, and we hope the court (rules that way) in June."
[Updated at 11:43 a.m. ET] According to Toobin, there were a lot of questions along these lines from Justices Scalia and Alito: We don’t know the effects of same sex parenting on children, so why don’t we wait and let the states go experiment? Why do we, the Supreme Court, have to get involved in this process?
Toobin said Roberts also seemed sympathetic to these questions.
[Updated at 11:39 a.m. ET] The attorney general and the governor of California have refused to defend Prop 8. So the question, Toobin says, is "Who can defend the law? Who has the standing?" The answer to that question will be key to resolving the case.
Conservative Justices Scalia, Alito and Roberts were "very hostile of idea of the court imposing same sex marriage," according to Toobin. The four Democratic justices seemed favorably disposed.
Justice Kennedy seemed like he was in the middle, he said things that would "give comfort for both sides," Toobin says. Kennedy suggested the issue was brought prematurely before the court.
[Updated at 11:37 a.m. ET] The justices seemed very focused on how Prop 8 affects children, with Justice Kagan at some point suggesting that California have a law allowing same-sex marriage for people past child-bearing age, Toobin said.
Kagan said, according to Toobin: “I assure you if two 55 year old people, there aren’t a lot of children (coming from that marriage).”
[Updated at 11:34 a.m. ET] "This was a deeply divided Supreme Court, a court that seemed groping for answers," CNN senior legal analyst Jeffrey Toobin said after watching the arguments. "Now I think its even harder to predict the result of this case after hearing this argument."
[Updated at 11:31 a.m. ET] Oral arguments have wrapped up, according to CNN Supreme Court producer Bill Mears. They went just a bit over schedule, lasting about one hour and 20 minutes.
[Updated at 11:23 a.m. ET] While we wait on word from the courthouse, consider this: A new CNN/ORC International Poll indicates that 53% of Americans support same-sex marriage. In the same survey, 57% of respondents said they had a family member or close friend who is gay or lesbian.
Here's a look at the issue, by the numbers.
[Updated at 11:06 a.m. ET] The same-sex marriage debate is a huge issue, and the lawyers inside were penciled in for an hour to make their cases. Doesn't sound like much time, but to be fair, the oral arguments regarding the Affordable Care Act (aka "Obamacare") last March lasted roughly two hours.
Tomorrow's DOMA arguments have been given one hour and 50 minutes. We'll see if they stay on schedule today.
[Updated at 10:46 a.m. ET] If all is going to plan, Jean Podrasky, a lesbian whose first cousin happens to be Chief Justice John Roberts, is inside the court hearing the arguments.
"I know that my cousin is a good man," she wrote in an op-ed this week. "I feel confident that John is wise enough to see that society is becoming more accepting of the humanity of same-sex couples and the simple truth that we deserve to be treated with dignity, respect, and equality under the law."

Lawyers for James Holmes, the Aurora, Colorado, mass shooting suspect, took aim against the state's insanity defense laws in court documents made public Friday.
"Colorado's statutory scheme regarding the affirmative defense of insanity, and the introduction of any 'mental condition' evidence at trial or sentencing, is unconstitutional in many individual respects," they wrote in a 60-page motion and brief filed Thursday.
The lawyers said parts of the state's insanity defense laws are unconstitutional.
Among other issues, they cited the requirement that a defendant "cooperate" with examining psychiatrists as a violation of the defendant's privilege against compelled self-incrimination.
Prosecutors have not said whether they will pursue the death penalty against Holmes, who is charged with 166 counts, including murder, attempted murder and other offenses in the July 20 shooting rampage in a movie theater that left 12 people dead and scores injured.
Holmes is awaiting formal arraignment on the charges.FULL STORY

Former Chicago-area police sergeant Drew Peterson was sentenced Thursday to 38 years in prison - with credit for nearly four years in jail - for the 2004 murder of his ex-wife, Kathleen Savio, a prosecution spokesman in Illinois said.
Peterson plans to appeal the sentence, one of this lawyers said.
Peterson was convicted of murder last September. Savio - Peterson's third wife - was found dead in her dry, clean bathtub on March 1, 2004
The headline-grabbing case did not arise until after Peterson's fourth wife, Stacy, disappeared in October 2007. It was during the search for Stacy Peterson - who has not been found - that investigators said they would look again into Savio's death, which was initially ruled an accidental drowning.

Georgia had asked the justices to lift the stay, which was granted minutes before Hill had been scheduled to die by lethal injection Tuesday night.
