More than 30 workplace disputes, including one involving a national wholesale company, are now on hold in a federal appeals court in Washington as the U.S. Justice Department mulls whether to challenge a ruling that voided President Barack Obama’s recess appointments to the National Labor Relations Board.

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on January 25 concluded in Noel Canning v. NLRB that the president’s recess appointments to the labor board exceeded presidential authority. Since then, the circuit has ordered 34 lead cases held in abeyance pending the resolution of the recess appointment dispute, according to the court.
