(a) Time within which to file notice of appeal. A party may appeal from a law judge's initial decision or appealable order by filing with the Board, and simultaneously serving on the other parties, a notice of appeal, within 10 days after the date on which the oral initial decision was rendered or the written initial decision or appealable order was served (except as provided in § 821.57(a) with respect to emergency proceedings). At any time before the time limit for filing an appeal from an initial decision or appealable order has passed, the law judge may, for good cause, reopen the matter on notice to the parties.

(b) Request for reconsideration of law judge's initial decision or order. A law judge may not reconsider an initial decision or appealable order after the time for appealing to the Board from the decision or order has expired, or after an appeal has been filed with the Board. However, a timely request for reconsideration by the law judge of the initial decision or appealable order, filed before an appeal to the Board is taken, will stay the deadline for filing an appeal until 10 days after the date on which the law judge serves his or her decision on the reconsideration request. For the purpose of this paragraph, if a request for reconsideration and a notice of appeal are filed on the same day, the reconsideration request will be deemed to have been filed first.
