UPDATE: The court holds that the ban on same-sex marriage violates equal protection.
AND: Here's the opinion [PDF].
ALSO: What Prop 8 did, the court writes, was take away the designation "marriage," and that word matters:
We are excited to see someone ask, "Will you marry me?", whether on bended knee or in text splashed across a stadium Jumbotron. Certainly it would not have the same effect to see "Will you enter into a registered domestic partnership with me?". Groucho Marx's one-liner, "Marriage is a wonderful institution... but who wants to live in an institution?" would lack its punch if the word "marriage" were replaced with the alternative phrase. So too with Shakespeare's "A young man married is a man that's marr'd," Lincoln's "Marriage is neither heaven no hell, it is simply purgatory," and Sinatra's "A man doesn't know what happiness is until he's married. By then it's too late." We see tropes like "marrying for love" versus "marrying for money" played out again and again in our films and literature because of the recognized importance of the marriage relationship. Had Marilyn Monroe's film been called How to Register a Domestic Partnership with a Millionaire, it would not have conveyed the same meaning as did her famous movie....You get the idea. The judges are old. I mean... marriage — even just the word — matters.
