BREYER: The way not to do it -- hold your finger up to the political winds. That's not the job of the judge. The judges are not politicians... [W]hat we do is we look to the text, the history, the traditions, the precedent, the values that underlie the particular constitutional phrase, and consequences that if you decide this way, does it further the values or does it undermine the values.There, that's his theory of interpretation, summarized. The key is identifying values underlying the text and the real-world consequences of the decisions. That may seem to give the judge a lot of leeway, but Breyer's effort is to convince people that this is real judging, even though the stricter textualists say it isn't. If people accept this argument, then they see that the liberal Justices — like the conservative Justices — are doing something that isn't some sort of covert politics and they'll have confidence in the courts.
This brings up the topic of the Justices at the State of the Union address. Wallace shows the video clip of Obama scolding the Justices — who were sitting right in front of him — about the decision in Citizens United. There's also a clip of Chief Justice Roberts saying that he's troubled by the "image... of one branch of government standing up, literally surrounding the Supreme Court, cheering and hollering, while the court, according to the requirements of protocol, has to sit there expressionless." Breyer disagrees. It's good for the Justices to hear from people who think different things: "It doesn't bother me and part of me says, 'Good.'"
