In a surprising development, the NLRB has dropped its appeal of the D.C. Circuit’s decision invalidating its “Quickie Election Rules.”

By those rules, which we’ve blogged about previously, the Board sought to, among other things, shorten the already-brief period of time between the filing of an election petition and the holding of an election. The Board adopted the rules in late 2011 and intended on instituting them in April 2012, but the D.C. Circuit ruled in May 2012 that the Board lacked a proper quorum when the rules were adopted and, accordingly, were invalid.

The Board, which had previously attempted, but failed, to get the Court to reconsider its decision, has yet to comment on the dropping of its appeal.
