The Supreme Court is blocking a broadcast of the trial on California's same-sex marriage ban, at least for the first few days.
The federal trial is scheduled to begin today in San Francisco. It will consider whether the Proposition 8 gay marriage ban approved by California voters in November 2008 is legal.
The high court on Monday said it will not allow video of the trial to be posted on YouTube.com, even with a delay, until the justices have more time to consider the issue. It said that Monday's order will be in place at least until Wednesday. Opponents of the broadcast say they fear witness testimony might be affected if cameras are present. Justice Stephen Breyer said he would have allowed cameras while the court considers the matter.
