On December 15, 2014, The National Labor Relations Board (NLRB) issued a final rule designed to speed up the union election process. The “ambush” rule was first promulgated in June 2011, and immediately thereafter the U.S. Chamber and the Coalition for a Democratic Workplace filed suit challenging the rule. On May 14, 2012, the United States District Court for the District of Columbia ruled on procedural grounds that the expedited election rules were invalid. The Board did not have a valid quorum when it first vote for the proposed regulations. The NLRB ended up reissuing the same rules on February 5, 2014, taking comments for 90 days.
