Three recess appointments to the NLRB

Obama has made three recess appointments to the NLRB.

As part of a deal with GOP to pass another group of nominees, Reid agreed to hold pro-forma sessions that purportedly keep the Senate in session over the Christmas recess.

Politico suggests that there will be some form of legal challenge, I can't see how that can work out for the GOP. It is unclear who has standing to bring a case. Even if the issue of standing is decided it is highly unlikely that a case would be decided before the recess appointments end. In the unlikely event that a court was to grant an injunction, Reid could call an additional recess and allow Obama to reappoint everyone.
