This is a notation I’ve never seen before in Law v. Siegel (the other case argued today that no one cares about).
JUSTICE SCALIA: Excuse me. Will you crank up your — your thing? I can’t you hear well enough. That’s good.
I assume the Justice wanted the lawyer to crank up the lectern, so the mic was closer to his mouth.
I think this is Matthew Hellman’s first argument. Congrats!
