ORDER
Federal Appellants and Intervenor-Appellants appeal the district courts order granting summary judgment in favor of Appellees. This appeal concerns the Presidents authority, conferred by the Outer Continental Shelf Lands Act (OCSLA), to return to disposition lands on the Outer Continental Shelf (OCS) that were previously withdrawn from exploration and development activities. Specifically, Appellees’ filed suit challenging Presidents Trumps Executive Order No. 13795 that purported to rescind President Obamas previous withdrawals of certain areas of the OCS in the Chukchi Sea, Beaufort Sea, and Atlantic Ocean.
On January 20, 2021, President Biden issued Executive Order No. 13990 that, among other things, purported to exercise President Bidens authority pursuant to Section 12(a) of OCSLA, 43 U.S.C. 1341(a), to reinstate President Obamas withdrawals. President Bidens Executive Order also revoked President Trumps Executive Order that formed the basis of this controversy. We ordered the parties to submit supplemental briefs regarding the impact of President Bidens Executive Order on these appeals. The parties argue President Bidens revocation of President Trumps Executive Order rendered these appeals moot. We agree.
We lack jurisdiction to consider “moot questions ․ or to declare principles or rules of law which cannot affect the matter in issue in the case before [us].” Church of Scientology of Cal. v. United States, 506 U.S. 9, 12, 113 S.Ct. 447, 121 L.Ed.2d 313 (1992) (quoting Mills v. Green, 159 U.S. 651, 653, 16 S.Ct. 132, 40 L.Ed. 293 (1895)). “A case becomes moot—and therefore no longer a ‘Case’ or ‘Controversy’ for purposes of Article III—‘when the issues presented are no longer ‘live’ or the parties lack a legally cognizable interest in the outcome.’ ” Already, LLC v. Nike, Inc., 568 U.S. 85, 91, 133 S.Ct. 721, 184 L.Ed.2d 553 (2013).
Because the terms of the challenged Executive Order are no longer in effect, the relevant areas of the OCS in the Chukchi Sea, Beaufort Sea, and Atlantic Ocean will be withdrawn from exploration and development activities regardless of the outcome of these appeals. See Trump v. Hawaii, ––– U.S. ––––, 138 S. Ct. 377, 199 L.Ed.2d 275 (2017) (holding the appeal was moot because provisions of the challenged executive order “expired by [their] own terms”); See also Serv. Employees Intl Union v. Natl Union of Healthcare Workers, 598 F.3d 1061, 1068 (9th Cir. 2010) (“The test for mootness of an appeal is whether the appellate court can give the appellant any effective relief in the event that it decides the matter on the merits in his favor.”).
Accordingly, we vacate the judgment of the district court and remand with instructions to dismiss the case without prejudice. See United States v. Munsingwear, 340 U.S. 36, 39, 71 S.Ct. 104, 95 L.Ed. 36 (1950).
