So often, Scalia has chosen to ignore the obligation of a Supreme Court justice to be, and appear to be, impartial. He’s turned “judicial restraint” into an oxymoronic phrase. But what he did this week, when the court announced its decision on the Arizona immigration law, should be the end of the line.

Not content with issuing a fiery written dissent, Scalia offered a bench statement questioning President Obama’s decision to allow some immigrants who were brought to the United States illegally as children to stay. Obama’s move had nothing to do with the case in question. Scalia just wanted you to know where he stood.
