Further, an injunction before the appeal in this case has run its course will place gay and lesbian servicemembers in a position of grave uncertainty. If the Court's decision were later reversed, the military would be faced with the question of whether to discharge any servicemembers who have revealed their sexual orientation in reliance on this Court's decision and injunction. Such an injunction therefore should not be entered before appellate review has been completed.
The reason why DOJ apparently believes an appeal is justified is referenced most directly in the Memorandum of Law's argument that a stay should be entered because "At A Minimum, This Case Raises Serious Legal Questions."
In this section, DOJ attorney Paul Freeborne writes:
DADT has been challenged myriad times since it was enacted in 1993, and several appellate courts have upheld the constitutionality of this statute. Indeed, the Ninth Circuit in Witt rejected as inappropriate a facial challenge to the statute. Witt v. Dep’t of the Air Force, 527 F.3d 806, 819 (9th Cir. 2008). Therefore, at a minimum, this Court’s opinion holding DADT facially unconstitutional presents serious legal questions that favor entering a stay pending the resolution of this case by appellate courts.
It's a snip of the article, but it looks like from DOJ's perspective that to press forward is a better idea than to leave an opening for a later president or Congress to reverse the decision legislatively or thru 'activist judges' in the mold of Uncle Clarence and Darth Roberts.
