EXCERPT: The court said it wanted until at least Wednesday to consider arguments by backers of Proposition 8, the November 2008 ballot measure outlawing same-sex marriage, that camera coverage could result in threats or even violence against witnesses favoring the measure.

EXCERPT: Trial on YouTube?

— What happened: The Supreme Court issued a stay through Wednesday on a judge’s plans to allow the trial over California’s same-sex marriage ban to be uploaded to YouTube.

— What’s next: The court wants to hear more arguments on the issue. It could then lift its stay or make the camera ban permanent.

— How to watch the trial: Thirty-six seats are available to the public in the courtroom of Chief U.S. District Judge Vaughn Walker on the 17th floor of the federal courthouse, 450 Golden Gate Avenue in San Francisco. Another 150 seats are available in an overflow room on the 19th floor in which the trial is being shown on closed-circuit TV.
