EBEL, Circuit Judge.

In these consolidated appeals from two Chapter 13 bankruptcy proceedings, Debtors challenge the district court's order reversing confirmation of their reorganization plans and remanding their cases to the bankruptcy court for further proceedings. Because we lack jurisdiction to consider these appeals, we dismiss them.

I. BACKGROUND

In two separate bankruptcy proceedings, Debtors Doris and Edward Gordon and Stephen Pahs sought Chapter 13 bankruptcy relief in the Bankruptcy Court for the District of Colorado. That court requires Chapter 13 debtors, when they file their plans for reorganization, to use the court's model Chapter 13 plan. See L.B.R. 3015-1.1. In this case, although Debtors used the model plan, they modified it. The bankruptcy court confirmed Debtors' modified plans.

On appeal, however, the district court held that Debtors could not modify the plan and, therefore, reversed confirmation of Debtors' plans and remanded these cases to the bankruptcy court "for the entry of plan confirmation orders and any related orders consistent with [the district court's] opinion." (Aplt.App. at 405.) Debtors appeal that determination to this court.

II. PAHS' APPEAL NO. 12-1143 IS MOOT

After Pahs filed his appeal with this court, he and the Chapter 13 trustee agreed, during a hearing before the bankruptcy court, that Pahs would continue to make the payments required by the originally confirmed Chapter 13 plan while this appeal remained pending. When Pahs failed to make those payments, however, one of his creditors moved for the dismissal of Pahs' bankruptcy. See 11 U.S.C. § 1307(c)(6). After no one objected to the motion, the bankruptcy court granted it, dismissing Pahs' bankruptcy and undoing any action taken during the bankruptcy proceedings. In light of that dismissal, this court can no longer grant Pahs any relief and his appeal is, therefore, moot. See Rajala v. Gardner, 709 F.3d 1031, 1036 (10th Cir.2013), cert. denied, ___ U.S. ___, 134 S.Ct. 164, 187 L.Ed.2d 41 (2013). For that reason, we dismiss Pahs' appeal and remand his case to the district court with directions for that court to vacate its decision as moot to the extent it addressed Pahs' confirmation plan. We further direct the district court then to remand the case to the bankruptcy court so that that court, too, can vacate its decision regarding Pahs' modification of the model plan. See Dais-Naid, Inc. v. Phoenix Res. Cos. (In re Tex. Int'l Corp.), 974 F.2d 1246, 1247 (10th Cir.1992) (per curiam) (applying, e.g., United States v. Munsingwear, Inc., 340 U.S. 36, 39, 71 S.Ct. 104, 95 L.Ed. 36 (1950)); see also Camreta v. Greene, ___ U.S. ___, 131 S.Ct. 2020, 2035, 179 L.Ed.2d 1118 (2011).

III. WE LACK JURISDICTION TO CONSIDER THE GORDONS' APPEAL, NO. 12-1140

Because the Gordons' bankruptcy case remains pending, their appeal is not moot. But we, nevertheless, have no jurisdiction to consider this appeal because it is not taken from a final appealable decision and the parties have not invoked any mechanism that might permit an interlocutory appeal.1

As a starting point, the district court had jurisdiction, under 28 U.S.C. § 158(a)(1), to consider Bank of America's appeal from the bankruptcy court's order confirming the Gordons' plan. Section 158(a)(1) gives a district court jurisdiction to hear appeals from bankruptcy courts' "final judgments, orders, and decrees." The bankruptcy court's order confirming the Gordons' reorganization plan was such a final, appealable order. See Woolsey v. Citibank, N.A. (In re Woolsey), 696 F.3d 1266, 1268-69 (10th Cir.2012). "Indeed, in the world of bankruptcy proceedings — a world where cases continue on in many ways for many years and lack the usual final judgment of a criminal or traditional civil matter — confirmation of [a] ... plan `is as close to the final order as any the bankruptcy judge enters.'" Id. (quoting Interwest Bus. Equip., Inc. v. U.S. Tr. (In re Interwest Bus. Equip., Inc.), 23 F.3d 311, 315 (10th Cir.1994)).

28 U.S.C. § 158(d)(1) similarly gives this court jurisdiction to hear appeals from "all final decisions, judgments, orders, and decrees" entered by the district court in appeals taken from a bankruptcy court. (Emphasis added.) But, because the district court's order which the Gordons challenge on appeal reversed confirmation of their reorganization plan and remanded their case to the bankruptcy court for further proceedings, the district court's order was not a final order appealable under 28 U.S.C. § 158(d).

As a general rule, when a district court remands a case to the bankruptcy court for "significant further proceedings," that order is not final and appealable to this court. HealthTrio, Inc. v. Centennial River Corp. (In re HealthTrio, Inc.), 653 F.3d 1154, 1159 (10th Cir.2011); see also Strong v. W. United Life Assurance Co. (In re Tri-Valley Distrib., Inc.), 533 F.3d 1209, 1214 (10th Cir.2008) (per curiam). On the other hand, when the district court remands a case to the bankruptcy court for a "purely ministerial function," such as entering judgment for a party, or to "conduct additional proceedings involving little judicial discretion," that will not preclude the district court's decision from being final and appealable to this court under 28 U.S.C. § 158(d)(1). Colo. Judicial Dep't v. Sweeney (In re Sweeney), 492 F.3d 1189, 1190-91 (10th Cir.2007); Balcor Pension Investors V v. Wiston XXIV Ltd. P'ship (In re Wiston XXIV Ltd. P'ship), 988 F.2d 1012, 1013 (10th Cir.1993).

Here, the district court remanded the Gordons' case to the bankruptcy court "for the entry of plan confirmation orders and any related orders." (Aplt.App. at 405.) Although the district court's decision requires the Gordons, in proposing a new reorganization plan, to use the model Chapter 13 plan without modification, they would be free to revise the substantive portion of their plan. And, in any event, the bankruptcy court will have to give creditors notice of the new amended plan, permit time for any objections, and then conduct another confirmation hearing. All of which is to say, the district court remanded the Gordons' case to the bankruptcy court for "significant further proceedings," In re HealthTrio, Inc., 653 F.3d at 1159.

We reached a similar conclusion in Simons v. F.D.I.C. (In re Simons), 908 F.2d 643 (10th Cir.1990) (per curiam). In Simons, we held that a district court's decision, affirming the bankruptcy court's order rejecting confirmation of a reorganization plan and remanding the case to the bankruptcy court in order to enable debtors to seek confirmation of a new plan, was not a final decision appealable under § 158(d)(1). In re Simons, 908 F.2d at 644-45. Simons noted that its conclusion

Id. (citation omitted). "[S]o long as the bankruptcy proceeding itself has not been terminated, the debtor, unsuccessful with one reorganization plan, may always propose another plan for the bankruptcy court to review for confirmation, a prospect which negates any determination of finality under both principles cited above." Id. at 645 (citations omitted). "[T]he rejection of debtors' proposed plan may yet be considered on appeal from a final judgment either confirming an alternative plan, or dismissing the underlying petition or proceeding." Id. (citations omitted).

The parties concede that, under Simons, this court lacks jurisdiction to consider this appeal. But they argue that this court should overrule Simons because it "is incorrectly decided and in conflict with the law of other circuits." (Aple. Juris. Br. at 1.) This panel, however, cannot overrule Simons. See Schrock v. Wyeth, Inc., 727 F.3d 1273, 1279 (10th Cir.2013).2

The parties argue that it would be a waste of judicial resources for this court not to hear the merits of their appeals now. However, this court "cannot take jurisdiction where none is to be had." S. Ute Indian Tribe v. Leavitt, 564 F.3d 1198, 1209 (10th Cir.2009) (emphasis omitted). Debtors could have sought this court's immediate review of the district court's interlocutory remand order. See 28 U.S.C. § 1292(b); see also Conn. Nat'l Bank v. Germain, 503 U.S. 249, 252, 112 S.Ct. 1146, 117 L.Ed.2d 391 (1992); In re Woolsey, 696 F.3d at 1268. However, the Gordons did not seek § 1292 certification and we cannot certify on our own. See In re Woolsey, 696 F.3d at 1268 (in dicta, rejecting 28 U.S.C. § 1292(b) as a source of appellate jurisdiction because the parties did not invoke that procedure); Crossingham Trust v. Baines (In re Baines), 528 F.3d 806, 809 n. 2 (10th Cir.2008) (same).

The parties now request that, if this court dismisses this appeal for lack of appellate jurisdiction, we remand this case to the district court so the parties can seek certification of the district court's non-final remand order as appealable under 28 U.S.C. § 1292(b). Although we employed such a procedure in Temex Energy, Inc. v. Underwood, Wilson, Berry, Stein & Johnson, 968 F.2d 1003, 1005 (10th Cir.1992), we did so under more compelling circumstances. In Temex, the bankruptcy court entered a final order granting summary judgment to one party in an adversary proceeding. Id. at 1004. The district court reversed that decision, remanding because the bankruptcy court needed to make "a de novo determination of the facts." Id. The losing party appealed that determination to this court. Id. At that time, Tenth Circuit case law foreclosed use of the 28 U.S.C. § 1292(b) mechanism, for certifying an interlocutory decision as immediately appealable, in the bankruptcy context. Temex, 968 F.2d at 1004. While the Temex appeal was pending, however, the Supreme Court, in Germain, 503 U.S. at 252, 112 S.Ct. 1146, held that § 1292(b) was available to permit interlocutory appeals to circuit courts in the bankruptcy context. See Temex, 968 F.2d at 1004-05. In those circumstances, this court dismissed the appeal in Temex for lack of jurisdiction because the district court's decision was not final, but remanded the case to the district court to let that court "decide whether it wishes to certify this appeal for interlocutory review under § 1292(b)." Temex, 968 F.2d at 1005. It made sense for us to remand that case so the district court could decide, as an initial matter, whether or not to certify an immediate appeal under § 1292(b) because the district court had not previously "been given the option to consider certifying an interlocutory appeal." Id.

The circumstances presented here, however, do not warrant employing the same procedure. The § 1292(b) certification process for an immediate appeal was always available. Had the Gordons wanted to pursue an appeal immediately, instead of returning to the district court to propose a new plan, they could have requested § 1292(b) certification. They did not do so. And Bank of America had no basis to do so because it prevailed in the district court. These circumstances do not warrant a remand to permit the district court to consider certifying its earlier order for an immediate appeal.

IV. CONCLUSION

For the foregoing reasons, we DISMISS Pahs' appeal, No. 12-1143, as moot and remand his case to the district court with directions to vacate that court's decision as it pertains to Pahs, and further to remand this case to the bankruptcy court with directions to vacate that court's decision addressing Pahs' modification of the model Chapter 13 plan. We also DISMISS the Gordons' appeal, No. 12-1140, because we lack jurisdiction to consider their appeal from a non-final order.
