The U.S. Supreme Court, acting on an appeal from conservative defenders of California’s ban on same-sex marriage, overruled a federal judge in San Francisco today and blocked video coverage of the trial on YouTube.

In a brief order, the justices said they were halting the move by U.S. District Judge Vaughn Walker “permitting real-time streaming” of the trial, “except as it permits streaming to other rooms within the confines of the courthouse in which the trial is to be held.”

“Any additional order permitting broadcast of the proceedings is also stayed pending further order of this court,” the justices said. They added that the temporary order “will remain in effect until Wednesday, Jan. 13.”

The high court did not explain its reasoning.

Only Justice Stephen G. Breyer, a San Francisco native, dissented. “In my view, the court’s standard for granting a stay is not met” in this case, he wrote. “In particular, the papers filed, in my view, do not show a likelihood of ‘irreparable harm.’ ”
