Arguments began today in San Francisco in the federal case over Proposition 8. Judge Vaughn Walker pointedly questioned both sides over their arguments. He asked plaintiff counsel Ted Olson, who is representing two gay couples who were blocked from marrying in California after the passage of Proposition 8, why the state’s domestic-partnership law was not sufficient. He also called out defense counsel Charles Cooper over claims that legal same-sex marriage would “radically alter” traditional marriage and decrease the rate of heterosexual unions. Unfortunately, owing to an intervention from the Supreme Court, we can’t watch all the action. For now.
