If you were the lawyer given the task of defending the same-sex marriage bans in the Supreme Court, how would you approach the oral argument given that you are certain to lose? In almost every other case there is at least the possibility (however slim) of winning. Here, though, the Court’s treatment of the certiorari petitions and the stay requests makes the final outcome clear enough.
Do you treat the argument as a ceremony and perform your part? Do you go down guns blazing? Do you find some way to protest? (It would be possible, for example, to imagine someone just saying “We stand on our brief” and sitting down. I wonder if that’s ever happened in the Supreme Court.) It’s an odd situation.
