Well, just yetserday the Supreme Court agreed to hear the case against the NLRB Recess Appointments which also includes the appointment of Cordray.
I don't know what (besdies mayehm) will happen if SCOTUS invalidates the appointments. I don't want to worry about it, because there is plenty of other things to take up my time, but it's going to be closely watched when they do hear the case.
