What is striking about the DC Circuit opinion is not its bottom line, but the scope of its reasoning. Despite a pretense of constitutional modesty, the court decided the Recess Appointments issue on the broadest possible ground.
Congress can work mischief of its own. The Senate can hold up patently qualified nominees interminably. Or a majority of the House of Representatives may disable the Senate from going into "the recess" for no reason other than to preserve the filibustering prerogatives of a Senate minority.
Of course, the Senate is not intended to be a rubber stamp. But stalling nomination votes simply to keep laws from being enforced -- effectively repealing the laws that cannot be enforced without the nominees in place -- is utterly inconsistent with the Senate's proper confirmation role.
