If any motion in the nature of a motion to dismiss the complaint in its entirety is granted by the Administrative Law Judge before the filing of the Judge's decision, any party may obtain a review of such action by filing a request with the Board in Washington, DC, stating the grounds for review, and, immediately on such filing must serve a copy on the Regional Director and on the other parties. Unless such request for review is filed within 28 days from the date of the order of dismissal, the case will be closed.
