The Obama administration is employing multiple defenses to try to stave off an expected legal determination that the president’s controversial recess appointment of Richard Cordray as director of the Consumer Financial Protection Bureau is unconstitutional.Last week, the National Labor Relations Board announced it will not seek en banc rehearing in Noel Canning v. NLRB, in which the U.S. Court of Appeals for the District of Columbia Circuit af-firmed that the Jan. 4, 2012, recess appointments of three members to the board were unconstitutional.
