The California Credit Union League (“League”) filed this action against the City of Anaheim (“Anaheim”) seeking a declaratory judgment that the city’s application of a transient occupancy tax to credit union employees staying in local hotels violated 12 U.S.C. § 1768. The district court awarded summary judgment to the League and we affirmed.
See California Credit Union League v. City of Anaheim,
I.
The impetus of this case was a credit union seminar held in Anaheim in November of 1993. Federal credit union employees who attended the seminar stayed at the Disneyland Hotel in Anaheim and were assessed a transient occupancy tax pursuant to the Anaheim Municipal Code. The tax was 13% of the room rate charged by the hotel. The League responded to the tax by filing this lawsuit alleging that the transient tax as assessed against the credit union employees attending the seminar violated 12 U.S.C. § 1768. The district court granted the League summary judgment and we affirmed.
We noted that federal credit unions enjoy broad immunity from local taxation under Section 1768 and concluded that “[b]eeause the federal credit unions’ employees were attending to credit union business while staying at the Disneyland Hotel in Anaheim, they were ‘constituent parts’ of the credit union and immune from Anaheim’s transient occupancy tax under Section 1768.”
California Credit Union League,
The Supreme Court vacated our decision in light of its decision in
Arkansas v. Farm Credit Services of Central Arkansas
and remanded.
See City of Anaheim v. Cal. Credit Union League,
After the Supreme Court vacated our decision in this case in light of Farm Credit Services, we received a joint motion from the League and the United States to join the United States as co-plaintiff. Although the joint motion adequately discussed the joinder issue, the motion did not discuss whether the joinder of the United States as co-plaintiff would operate nunc pro tunc to “cure” the jurisdictional defect that existed in the prior proceedings. We, therefore, ordered the parties to file supplemental letter briefs addressing the issue of “whether joinder of the United States will ‘cure’ the jurisdictional defects that existed before the district court.”
We have received the parties’ supplemental briefs and now address whether the United States can join this action as a co-plaintiff and whether such belated join-der by the United States retroactively cures any jurisdictional defect that previously existed. We conclude that the United States can join this action as a co-plaintiff and that the United States belated joinder retroactively cures any jurisdictional defect that previously existed. We, therefore, reaffirm the district court’s judgment in favor of the League for the reasons stated in our prior opinion.
II.
Rule 21 of the Federal Rules of Civil Procedure provides in relevant part
*999
that “[p]arties may be dropped or added by order of the court on motion of any party or of its own initiative at any stage of the action and on such terms as are just.” Fed.R.Civ.P. 21. Although Rule 21 is not directly applicable to the courts of appeals, courts have consistently recognized that appellate courts can join parties pursuant to Rule 21 when a case is pending on appeal.
See Mullaney v. Anderson,
The United States is requesting the same relief as the League because the amicus brief filed by the United States sought a declaratory judgment that Anaheim’s transient occupancy tax impermissi-bly taxed the federal credit unions. To support its argument, the United States, like the League, cited 12 U.S.C. § 1768 and argued that the transient occupancy tax fell upon the various credit unions rather than the individual employees. The joinder of the United States at an earlier stage of this case would not have affected the course of this litigation because the district court and this court would have reached the same conclusions and granted the League the declaratory judgment it sought if the United States had participated in earlier proceedings. The final factor that supports joinder of the United States is the fact that Anaheim has no objection to this court granting the joint motion filed by the League and the United States. We, therefore, grant the joint motion to join the United States as co-plaintiff because the position of the United States is consistent with the position of the League and does not alter these proceedings and because the League has no objection to the United States joining this case as a plaintiff.
III.
Joinder of the United States as a co-plaintiff in this case does not, in and of itself, resolve the issue before us on remand because we must determine whether the joinder of the United States at the appellate level retroactively cures the jurisdictional defect identified by Farm Credit Services. The League and the United States argue that the belated joinder of the United States retroactively cures any jurisdictional defect because a retroactive cure will serve judicial economy and the interests of justice by avoiding a remand to the district court that will result in a pre-ordained judgment. Anaheim argues that federal subject matter jurisdiction must exist at the time the action is commenced and that the League cannot retroactively cure a jurisdictional defect that existed when the action was commenced through post-complaint conduct (i.e., the joinder of the United States in this court). We conclude that this is one of the rare cases where a jurisdictional defect can be retroactively cured at the appellate level.
In
Mullaney v. Anderson,
a fisherman’s union and its secretary-treasurer sued the Alaska tax commissioner challenging a licensing scheme adopted by the Territorial Legislature of Alaska. The tax commissioner argued for the first time in the Supreme Court that the union and its secretary-treasurer did not have standing to maintain the lawsuit. To cure any jurisdictional defect, the union and its secretary-treasurer moved to join two of its members as plaintiffs. Relying on Rule 21 of the Federal Rules of Civil Procedure, the Court granted the union’s motion even though it recognized that such joinder was
*1000
rare.
See Mullaney,
The Court reaffirmed
Mullaney
in
Newman-Green, Inc. v. Alfonzo-Larrain,
We decline to disturb that deeply rooted understanding of appellate power, particularly when requiring dismissal after years of litigation would impose unnecessary and wasteful burdens on the pai*ties, judges, and other litigants waiting for judicial attention. Appellate-level amendments to correct jurisdictional defects may not be the most intellectually satisfying approach to the spoiler problem, but ... because law is an instrument of governance rather than a hymn to intellectual beauty, some consideration must be given to practicalities.

Although a plurality of the Supreme Court has questioned the validity of
Mullaney

a defendant removed a state court action to federal court believing that a settlement between the plaintiff and the non-diverse defendant created complete diversity.

Under
Mullaney
and
Newman-Green,
the joinder of the United States as a plaintiff in this case has retroactively cured the jurisdictional defect identified by
Farm Credit Services.
If we were to remand this case with instructions to dismiss or to have the United States litigate the merits of the tax exemption issue, the United States and the League, as co-plaintiffs, would simply rely on the League’s original complaint against Anaheim, submit the same materials that the League already filed in the district court, and receive a preordained judgment in their favor. The United States and the League “should not be compelled to jump through these judicial hoops merely for the sake of hyper-technical jurisdictional purity,”
Newman-Green,
Anaheim argues that
Newman-Green
is distinguishable because in that case the court of appeals dismissed a dispensable party to cure a jurisdictional defect while in this case we are joining an indispensable party to cure a jurisdictional defect. This is a distinction without a difference. In both instances, the appellate court is bringing the proper parties before it to cure a jurisdictional defect and does so to prevent needless judicial proceedings without any resulting prejudice to the remaining parties. Moreover, even if Anaheim could distinguish this case from
Newman-Green,
it would be to no avail because
Mullaney
demonstrates that an appellate court can join parties to cure a jurisdictional defect just as an appellate court can dismiss parties to cure a jurisdictional defect.
See Mullaney,
Anaheim also argues that the joinder of the United States does not cure the jurisdictional defect that existed in this case because jurisdiction must exist at the time the action is commenced. This argument is misplaced because
Mullaney
and
Newman-Green
represent an exception to the general rule that jurisdiction must exist at the time the action is commenced.

We recognize that our authority to join a party to cure a jurisdictional defect must be “exercised sparingly,”
