Justice Scalia got a laugh from the gallery from his comment (beginning at 16:31 minutes in) where he says that all federal courts are intelligent. ;p
Was Scalia being serious?
Justice Ginsburg says something interesting.
“The Tax Injunction Act does not apply to penalties that are designed to induce compliance with the law rather than to raise revenue. And this is not a revenue-raising measure, because, if it’s successful, they won’t — nobody will pay the penalty and there will be no revenue to raise.”
