With only two current members sitting on the NLRB, the Supreme Court took oral argument over whether the 2-member panel has authority to hear the most complex cases or perhaps even the smallest of cases. At stake: whether more than 500 previous cases decided by the 2-member panel are valid. While these cases are still very much in play, President Obama may make the question moot in the future by recess appointing Craig Becker to the board, whose confirmation has (so far) been blocked by Senate Republicans.
