Initial Hearing En Banc on Request of a Party. The government in any proceeding,

or a party in a proceeding under 50 U.S.C. § 186l(f) or 50 U.S.C. § 188la(h)(4)-(S), may request that the matter be entertained from the outset by the full Court. However, initial hearings en bane are extraordinary and will be ordered only when a majority of the Judges determines that a matter is of such immediate and extraordinary importance that initial consideration by the en bane Court is necessary, and en bane review is feasible in light of applicable time constraints on Court action.
