In the "Morning Briefing," NCR's editor, Dennis Coday, called attention to an article about Justice Antonin Scalia's dissent in the Arizona case yesterday. It was stunning, even by Scalia's over-the-top standards. It was especially strange to see Scalia comment on President Obama's recent decision to give temporary work permits to undocumented immigrants who were brought here as children. I do think the President's decision reaises constitutional questions, but those questions were most certainly not before the Court yesterday. If Scalia wants to write a blog, he should do so, but he should leave such commentary out of an official document of the Court like a dissent. Perhaps it was payback for Obama's comments about Citizens United during his State of the Union speech two years ago. Vendetta is an Italian word after all. So, it "scatenato" or unhinged, and Scalia's dissent yesterday seems to exemplify it.
