                               ORDER AND JUDGMENT *


Before KELLY, MATHESON, and MORITZ, Circuit Judges. **


       A recitation of the facts in this case is unnecessary, as the parties are

familiar with them. Both parties agree we lack jurisdiction to hear this appeal,

though for different reasons. The Intervenor Defendant-Appellant maintains that

this case is constitutionally moot. The Plaintiffs-Appellees argue instead that we


       *
        This order and judgment is not binding precedent, except under the
doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,
however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th
Cir. R. 32.1.
       **
         After examining the briefs and the appellate record, this three-judge
panel has determined unanimously that oral argument would not be of material
assistance in the determination of this appeal. See Fed. R. App. P. 34(a); 10th
Cir. R. 34.1(G). The cause is therefore ordered submitted without oral argument.

                                         -2-
cannot reach the mootness issue because the district court’s remand was not a

final decision, see 28 U.S.C. § 1291, nor had the practical effect of an injunction,

see 28 U.S.C. § 1292(a)(1). We are not so constrained and may dismiss on any

jurisdictional ground. Cf. Ruhrgas AG v. Marathon Oil Co., 526 U.S. 574, 578

(1999); Boyce v. Ashcroft, 268 F.3d 953, 955 (10th Cir. 2001) (“Although the

court may have discretion to decide subject matter jurisdiction before reaching the

issue of mootness, however, we find no reason to do so in this case. The matter is

unquestionably moot. The court therefore vacates its judgment and remands to

the district court with directions to vacate its judgment as moot.”).

      Pending this appeal, the Office of Surface Mining Reclamation and

Enforcement, in accordance with the district court’s remand, issued a Revised

Environmental Assessment and Finding of No New Significant Impact as well as

re-approved the permit revision. Aplt. Notice of Supp. Auth. Because this case

now lacks a live case or controversy, we lack subject matter jurisdiction. New

Mexico ex rel. Richardson v. Bureau of Land Mgmt., 565 F.3d 683, 701 (10th Cir.

2009). Therefore, we dismiss the appeal as constitutionally moot and vacate the

district court’s March 2, 2015 opinion and order (Doc. 79), its April 6, 2015

remedies order (Doc. 83), and its Final Judgment (Doc. 86).
