See Constangy's Client Bulletins on the emergency injunction issued by the U.S. Court of Appeals for the District of Columbia Circuit, the decision of the district court in South Carolina invalidating the rule, and the decision of a district court in the District of Columbia finding that the NLRB had authority to issue but not enforce the rule. The rule treats any failure to post the Notice as an unfair labor practice and tolls the six-month limitation period for filing unfair labor practice charges if the Notice is not posted. The April 30 effective date has been postponed indefinitely.
