OPINION
This сase presents the question of whether a district court may, sua sponte, vacate a final judgment in a prior case not pending before the court because diversity jurisdiction, though it existed, was inadequately pled. We conclude that it cannot, and reverse.

Donald Snell filed this diversity tort action, caрtioned CV-00-00009 (hereinafter referred to as “the closed tort action”), in the United States District Court for the District of Montana. He named four parties as defendants: Cleveland, Inc.; Nicholas Faber, in his capacity as the sole shareholder of Cleveland, Inc.; and Nicholas and Patricia Fabеr, as the record landowners of the bar and adjoining property on which the accident underlying the case occurred. According to the allegations in the complaint, Snell — then nineteen years old' — spent the evening drinking and harassing other customers at defendant Cleveland, Inc.’s tavern in Blаine County, Montana. Snell’s debauch came to an abrupt end when he left the bar and fell off a forty-foot drop near the bar’s parking lot, suffering significant physical injuries. Snell sought damages in tort from the defendants.
The complaint inadequately alleged the facts necessary to establish diversity jurisdiсtion.
Mantin v. Broad. Music, Inc.,
The case was originally assigned to United States District Judge Paul G. Hatfield, but the parties consented to proceed before a United States Magistrate Judge pursuant to 28 U.S.C. § 636(c). The parties reached a settlement of the claims. Based on the settlement, the magistrate judge dismissed the claims against the Fa-bers with prejudice, and a confession of judgment was entered against Cleveland, Inc., in the amount of $750,000. In return for а covenant not to execute the judgment, Cleveland, Inc. assigned its claims against its insurer, Acceptance Insurance Co., to Snell. Acceptance Insurance Co. had refused to tender a defense of Cleve *825 land, Inc. in the suit. The file was then closed.
A year later, based on the assignment of claims, Snell filed a separаte suit against Acceptance Insurance Co., captioned DV-00-00148 (hereinafter referred to as “the new insurance lawsuit”). Although filed in the same division of the District of Montana, it was assigned to a different district court judge than the judge who sat on the closed tort action. At a hearing on cross-motions for summary judgment, the judge in the new insurance, lawsuit, informed the parties — apparently out of the blue — that he had discovered jurisdictional pleading defects in the closed tort action. The court correctly pointed out that the complaint in the closed tort action had alleged thе residency, but not the citizenship, of the individual parties and was therefore inadequate to establish diversity jurisdiction. What the court did next is the subject of this appeal.
Brushing aside the fact that none of the parties or the judge assigned to the closed tort action had raised the jurisdictional plеading defect, that all the parties to the closed tort action were not present, that no question existed that the parties actually were diverse, that another judge had presided over the case, and that a final judgment had been entered, the district court sua sponte vacated the judgment in the closed tort action and dismissed not just the complaint but the entire action. 1 Montana’s three-year statute of limitations for tort actions had already run on the claims alleged in the closed tort action. Mont. Code Ann. § 27-2-204. Thus, although the dismissal was without prejudice on its face, it precluded all further action in the closed tort action. 2 Snell timely appealed the district court’s vacation of the previous judgment and its dismissal of the closed tort action. 3
We review de novo a district court’s assumption of jurisdiction.

Neither the Federal Rules of Civil Procedure nor case law provides any basis for the district court’s action in this case. Under the Federal Rules, a court may amend or vacate a prior judgment “[o]n motion and upon such terms as are just.” Fed.R.Civ.P. 60(b) (emрhasis added). The rule states, in relevant part:
*826 On motion and upon such terms as are just, the court may relieve a party or a party’s legal representative from a final judgment, order, or proceeding for the following reasons: (1) mistake, inadvertence, surprise, or excusable neglect; (2) newly discovered evidence which by due diligence could not have been discovered in time to move for a new trial under Rule 59(b); (3) fraud (whether heretofore denominated intrinsic or extrinsic), misrepresentation, or other misconduct of an adverse party; (4) the judgment is void; (5) the judgment has been satisfiеd, released, or discharged, or a prior judgment upon which it is based has been reversed or other wise vacated, or it is no longer equitable that the judgment should have prospective application; or (6) any other reason justifying relief from the operation of the judgment. The motion shall be made within a reasonable time, and for reasons (1), (2), and (3) not more than one year after the judgment, order, or proceeding was entered or taken. A motion under this subdivision (b) does not affect the finality of a judgment or suspend its operation. This rule does not limit the power of a court to еntertain an independent action to relieve a party from a judgment, order, or proceeding, or to grant relief to a defendant not actually personally notified as provided in Title 28, U.S.C., § 1655, or to set aside a judgment for fraud upon the court.
Fed.R.Civ.P. 60(b).
Under the rule, a court may entertain an indeрendent action by a party to set aside or modify a prior judgment.
Id.; Houck ex rel. United States v. Folding Carton Admin. Comm.,
The only provisions of Fed.R.Civ.P. 60 that allow for sua sponte action by a court involve extremely minor and extremely dire circumstances. Subsection (a) allows a district court to correct “[clerical mistakes in judgments, orders or other parts of the record ... at any time of its own initiative.” Fed.R.Civ.P. 60(a). Subsection (b) states that the Rulе does not limit a court’s ability “to set aside a judgment for fraud upon the court.” Fed.R.Civ.P. 60(b). Neither subsection applies in this case. The judgment contained no clerical error and the plaintiffs failure to plead the facts necessary to establish diversity jurisdiction was certainly not a fraud upon the court.
Federal Rule of Civil Procedure 12(h)(3)

provides that a court may raise the question of subject matter jurisdiction,
sua sponte,
at any time during the pendency of the action, even on appeal.
Summers v. Interstate Tractor & Equip. Co.,
*827
Case law further undermines any basis for the district court’s actions. “[T]he social interest in expedition and finality in litigation” weighs strongly against collateral attacks on final judgments.
Bell v. Eastman Kodak Co.,
The bar on collateral attacks to final judgments remains in force even when defective allegations of diversity motivate the collateral attack. As former Chief Judge Walter Pope noted:
Thus it may properly by said that existence of diversity of citizenship or of the requisite amount in controversy, is a prerequisite to the jurisdiction of a federal court; but it is also clear that if the court in question determines that these requirements are satisfied, and that it has jurisdiction, it is certain that such a determination, even if demonstrably wrong, is not a nullity or a truly void judgment, for it cannot be questioned collaterally.
Yanow v. Weyerhaeuser S.S. Co.,
As Judge Pope noted, an important distinction exists “between cases where certain facts are strictly jurisdictional in the sense that without them the act of the court is a mere nullity, and those cases in which the facts are only quasi-jurisdictional.”

Id.
(citing
Noble v. Union River Logging R. Co.,
Where the facts upon which jurisdiction depends are quasi-jurisdictional in the sense here described, the determination by the court of its jurisdiction is ... conclusive and binding in every collateral proceeding; and it matters not that the court’s determination of its own jurisdiction is arrivеd at in error, even though the error of adjudication is apparent upon the face of the record.
Yanow,
Thus, precedent weighs strongly against the actions of the district court in this case, as do the Federal Rules. Despite the pleading defect in the closed tort action, the district court assigned to the new insurance lawsuit was not free to attack the final judgment entered in the closed tort action. At most, the district court *828 might have suggested to the plaintiff in the closed tort action that he could move to amend the complaint in order to correct the record. Such a mоtion would have been filed in the closed tort action, giving the judge assigned to that action the opportunity to allow leave to amend under Fed.R.Civ.P. 15 and 28 U.S.C § 1653. Beyond such a suggestion, however, the judge overseeing the new insurance lawsuit was not free to challenge the judgment in the closed tort aсtion. Accordingly, we vacate the judgment and order of the district court vacating this action and dismissing the case. The original judgment in the closed tort action is thus in force, albeit with the jurisdictional pleading defect still remaining. Although the judgment would stand, absent a motion or independent action by a party, we allow for amendment in order to put this matter, finally, to rest.
III
Under 28 U.S.C § 1653, we have the authority to grant leave to amend a complaint in order to cure defective allegations of jurisdiction.
6
The primary purpose of § 1653 is to permit correction of incorrect statements about extаnt jurisdiction.
Newman-Green, Inc. v. Alfonzo-Larrain,
We have previously permitted amendment of complaints at the appellate level in order to correct defective jurisdictional allegations.
Blue Ridge Ins. Co. v. Stane-wich,
Here, it is undisputed that complete diversity of citizenship actually existed. Thus, pursuant to § 1653, we order the pleadings amended, nunc pro tunc, to correct the defective allegations concerning the proper diversity of parties.
The district court’s judgment is REVERSED; the district court’s order dismissing the complaint is VACATED; the complaint is ordered AMENDED, nunc pro tunc; and the original judgment is ordered REINSTATED. Each party shall bear its or their own costs.
Notes
. Rather than granting leave to amend the complaint in the new insurance lawsuit, in which it had just entertained argument for summary judgment, the district court dismissed that suit without prejudice as well.
. Accordingly, it is effectively a dismissal with prejudice and a final decision from which plaintiff is entitled to appeal. 28 U.S.C. § 1291;
Stanger v. City of Santa Cruz,
.The district court’s action in dismissing the new insurance lawsuit because divеrsity of citizenship was inadequately pled is not before us.
. Fed.R.Civ.P. 12(h)(3) provides: "Whenever it appears by suggestion of the parties or otherwise that the court lacks jurisdiction of the subject matter, the court shall dismiss the action."
. Put another way, there is a difference between jurisdictional defects that render a judgment void
ab initio, see, e.g., Gruntz v. County of Los Angeles (In re Gruntz),
.
The statute provides: "Defective allegations of jurisdiction may be amended, upon terms, in trial or appellate courts.” 28 U.S.C. § 1653. Under this provisiоn, the district court originally assigned to this case could— and should — have allowed amendment if it had been made aware of the pleading defect. Certainly, it should not have dismissed without leave to amend. -Dismissal without leave to amend is improper unless it is clear, upon de novo review, that the сomplaint could not be saved by amendment.
