The Herrick Company, Inc. and Norton Herrick (collectively “Herrick” or “plaintiffs”) and SCS Communications, Inc. and its principal Stephen C. Swid (collectively “SCS/Swid”) appeal and cross-appeal in this diversity suit from a judgment, en
I. BACKGROUND
This complicated appeal arises out of a much simpler business deal that went wrong. In that deal, Herrick and SCS/ Swid planned the joint acquisition of the Orieander Group, a manufacturer of bicycle accessories. At the heart of the lawsuit is an August 16, 1993 Letter Agreement (the “Letter Agreement”) executed by Herrick Company, Inc., SCS Communications, Inc., and TOG Acquisition Co. (the entity to be used as the acquisition vehicle). Plaintiffs claim that the Letter Agreement is a legally binding contract creating a joint venture to acquire the Orieander Group.
Negotiations about the structure of the acquisition vehicle and about the rights and responsibilities of the parties thereto broke down on November 21, 1993, and, eight days later, on November 29, SCS and TOG Acquisition Co. proceеded, with the assistance of the law firm Skadden, Arps, Slate, Meagher & Flom (“Skadden”) and one of its partners, Mark Smith, to complete the acquisition of the Orieander Group on their own. Herrick responded by bringing the lawsuit now before us, in which it claims it was improperly deprived of its half-share in the joint acquisition. Specifically, Herrick sued the businesses and business people involved in the deal— (1) SCS/Swid, (2) SCS Communications director Stephen Weinroth, (3) Vetta Sports, Inc. (as successor to TOG Acquisition Co.), and (4) TOG Acquisition Co. officers Richard Scheinberg & Henry N. Chan — (collectively, the “business defendants”) asserting causes of action; based on the Letter Agreement, for breach of contract, breach of fiduciary duty, fraudulent inducement, and knowing participation in a breach of fiduciary duty. In addition, Herrick sued the law firm and lawyer involved in the deal — Skadden and Skadden partner Mark Smith — asserting a variety of causes of action involving' breaches of fiduciary duties allegedly created by Skadderis role as attorney to the joint venture аnd to Herrick as one of the joint venturers. Plaintiffs sought both compensatory and punitive damages.
The several parties all moved and cross-moved for summary judgment. In relevant part, (1) the business defendants moved for summary judgment dismissing plaintiffs’ complaint on the ground (among others) that the Letter Agreement was not an enforceable contract and that it did not create a joint venture; and (2) plaintiffs cross-moved for summary judgment against all defendants on all claims, and in particular against the business defendants on the ground that the Letter Agreement
The district court decided the motions for summary judgment in an Opinion and Order dated December 3, 1996. In that Opinion and Order, the district court rejected the business defendants’ contention that the Letter Agreement was no more than “a classic agreement to agree which did not even create enforceable obligations let alone a joint venture,” and found instead that the Letter Agreement was, as a matter of law, a valid and enforceable contract creating a joint venture to acquire the Orleander Group. At the same time, however, the district court refused to hold that the business defendants had breached the contract created by the Letter Agreement, finding that the questions of breach and damages “appear to be genuine issues of material fact for the jury to determine,” and hence not appropriate for summary judgment.
The case therefore went to trial (before a jury) on the issues of the business defendants’ breach of the Letter Agreement, Skadden’s breach of fiduciary duties, and damages. The trial began on January 12, 1999, and on January 15 (the fourth day of the trial), counsel for plaintiffs and for all defendants other than SCS/Swid announced in open court that they had reached a settlement agreement (whose terms were not revealed to the jury and remain sealed or redacted from the district court’s unsealed orders). Consequеntly, all defendants other than SCS/Swid were excused from the remainder of the trial. The district court, although not until July 23, entered stipulations and orders dismissing plaintiffs’ case against the settling defendants but retaining jurisdiction over any disputes relating to the settlement.
Plaintiffs continued to present their case against SCS/Swid, and, on February 10, 1999, the jury returned a verdict finding (1) SCS liable to plaintiffs for breach of contract and breach of fiduciary duty, (2) Swid, as SCS’s alter ego, liable to plaintiffs for breach of contract and breach of fiduciary duty, and (3) Swid liable to plaintiffs for knowing participation in a breach of fiduciary duty. The jury awarded plaintiffs $10,549,000 in damages, and on February 25, the district court entered a judgment in the amount of $10,549,000 plus prejudgment and post-judgment interest, subject to SCS/Swid’s right to a setoff due to plaintiffs’ settlement with the other defendants.
Uncertainty about the amount of this setoff caused the district court to vacate entry of that judgment. On August 12, 1999, the district court entered a new judgment, (1) awarding Herrick damages in the amount of $10,549,000 plus prejudgment interest, and (2) granting SCS/ Swid’s motion to amеnd their answers (pursuant to Fed.R.Civ.P. 15) in order (a)
Both Herrick and SCS/Swid filed timely notices of appeal. Herrick seeks reversal of the district court’s order that the present discounted value of the settlement should be set off against the jury verdict. Specifically, Herrick argues that the district court (1) misapplied (in several ways) New York state law governing setoffs, (2) violated Herrick’s constitutional right to a jury trial, and (3) improperly credited toward the setoff settlement payments that Herrick would receive only in the future. SCS/Swid seeks reversal of “each and every portion” of the August 12 judgment, “as well as all prior decisions and orders” in the case. SCS/Swid argues (1) that the district court’s finding, on summary judgment, that the August 16, 1993 Letter Agreement constituted a binding contract creating a joint venture was erroneous, (2) that the district court made several erroneous and prejudicial evidentiary rulings at trial, (3) that the district court issued erroneous damage instructions, and (4) that the jury’s verdict holding Swid liable as SCS’s alter ego and also for knowingly participating in a breach of fiduciary duty was unsupportеd by the evidence. Finally, in response to an order issued by our Court on June 15, 2000, the parties submitted letter briefs addressing the question, first raised by SCS/Swid in its post-judgment motions below, of whether federal subject matter jurisdiction is proper in this case.
II. DISCUSSION
Our disposition of the present appeal focuses on only the last of these questions — whether we enjoy federal subject matter jurisdiction. Because we find that federal subject matter jurisdiction is lacking as the case is presently structured and that, as an appellate court, we cannot determine whether the defect in jurisdiction may properly be cured, our inquiry does not pass beyond that question. We therefore remand the case to the district court for further consideration.
We are aware, in ordering the remand, that this has been an arduous and expensive lawsuit, but subject matter jurisdiction remains “an unwaivable sine qua non for the exercise of federal judicial power,” Curley v. Brignoli, Curley & Roberts Assocs.,
A. Diversity
In the case before us, it is unquestioned that the only source of federal subject matter jurisdiction is diversity of citizenship pursuant to 28 U.S.C. § 1332. In relevant part, that statute establishes that diversity jurisdiction exists over civil actions (1) between “citizens of different States” and (2) between “citizens of a State and citizens or subjects of a foreign state.” 28 U.S.C. § 1332(a)(1) & (2). We must, therefore, consider whether the parties in the case before us fall into either of these categories. We focus, in particular, on whether Skadden’s participation in the case destroys diversity under this statute as it has been interpreted.
We begin this enquiry with the axiomatic observation that diversity jurisdiction is available only when all adverse parties to a litigation are completely diverse in their citizenships. See Owen Equip. & Erection Co. v. Kroger,
Putting these two principles together and applying them to Skadden generates the conclusion that if Skadden has among its partners any U.S. citizens who are domiciled abroad, then Skadden and Herrick (which is a citizen of Florida) are non-diverse. And this is precisely the conclusion SCS/Swid urges upon us, providing' — ■ by way of identification of possible U.S. citizens domiciled abrоad — biographical materials, compiled by Skadden itself, that describe several Skadden partners as educated in the United States and belonging to American State bars, but permanently living in a foreign city and working at a foreign office.
Furthermore, it is well established that “[t]he party seeking to invoke jurisdiction under 28 U.S.C. § 1332 bears the burden of demonstrating that the grounds for diversity exist and that diver
A somewhat unusual feature of this case, however, precludes that conclusion in the absence of further analysis. The evidence that SCS/Swid has marshaled against Skadden’s diversity (involving, as it does, Skadden partners who appear to have U.S. roots and more recent long-term residence abroad) indicates that if these partners have indeed established a foreign domicile, such a domicile constitutes a change from an earlier, although unidentified, U.S. domicile. This, Herrick argues, implicates the venerable rule that “[wjhere a change of domicile is alleged, the burden of proof rests upon the party making the allegation.” Desmare v. United States, 93 U.S. (3 Otto.) 605, 610,
On the specific combination of facts before us — under which the allegation of diversity relies on old domiciles and the denial of diversity relies on changes in domicile — -the rules articulated by McNutt (that the party invoking federal jurisdiction bears the burden of proving diversity) and by Desmare (that the party alleging a change of domicile bears the burden of proving that change) cut in opposite directions. We must, therefore, decide how to resolve the tension between them. As it happens, this combination of circumstances, though somewhat unusual, is far from unprecedented.
One response to the potential conflict between the McNutt and Desmare rules has been to hold that the ultimate burden of persuasion concerning diversity and hence domicile remains with the party invoking federal jurisdiction and to treat (at least when the two rules are in tension) the Desmare rule that the party alleging a change in domicile bears the burden of proving that change to refer to the onus of production only. Thus the Fifth Circuit has said that “[wjhile some opinions seem to imply that the burden of persuasion rests with the party attempting to show a change of domicile, this is an overstatement. The proper rule is that the party attempting to show a change assumes the burden of going forward on that issue. The ultimate burden on the issue of jurisdiction rests with the plaintiff or the party invoking federal jurisdiction.” Coury v. Prot,
We have not wholly joined in this approach, noting that “it misconceives the purpose of [the] hallowed [Desmarе] presumption, which, unlike evidentiary presumptions, is premised not on probabilities or on which party has more ready access to pertinent information, but rather on a judicial policy determination that in ascertaining diversity jurisdiction in a highly
The Gutierrez holding, however, is expressly tied to (indeed it is in explicitly a “corollary” of) the “purpose” it was designed to serve, namely the need, in a mobile society, “to fix domicile with some reasonable certainty at the threshold of litigation.” Id. at 427 n. 1. And for this reason, a party seeking to challenge diversity by alleging a change of domicile does not, even under Gutierrez, bear the burden of proving that change if the party seeking to establish diversity has not carried its (prior) burden of establishing a specific initial domicile from which the change would be a departure.
Even under Gutierrez, therefore, the party invoking diversity jurisdiction continues to bear, as McNutt teaches, the burden of persuasion in establishing specific initial domiciles that support the existence of diversity jurisdiction (and from which the alleged changes in domicile represent a departure). Accordingly, the burden of establishing diversity in the case at bar remains (for the present) with Herrick, which must establish actual initial, diverse, domestic domiciles for the рartners SCS/Swid claims now live and work abroad. Only after such original domiciles were demonstrated would SCS/Swid bear the burden of proving that they had been abandoned for the foreign domiciles that it alleges currently apply.
The sole evidence Herrick has presented in support of its assertion that Skadden is diverse is Skadden’s pre-trial admission that diversity jurisdiction existed. This admission is a “strong factor in favor of a similar judicial finding,” Gutierrez,
Supplemental Jurisdiction
It is conceivable, nevertheless, that the federal courts, in connection with the dis
Consideration of the first of these need not detain us long. In the (diversity) case at bar, supplemental jurisdiction is alleged not merely over a pendent claim but rather over a claim involving a party as to whom there would be no independent federal subject matter jurisdiction. See Aldinger v. Howard,
But even though the first effort to bring the dispute involving Skadden within the supplemental jurisdiction of the federal courts fails, the second effort might still succeed. Thus, although there may have been no federal jurisdiction over the lawsuit at the time it was filed, the subsequent settlement with Skadden may have cured the earlier defect. And indeed, Herrick argues precisely this. It contends that regardless of what may have been true earlier, at least from the time of the settlement onwards, there has been no defect of federal jurisdiction.
In presenting this argument, Herrick does not deny that, although the district court dismissed the case against Skadden, it expressly retained jurisdiction over “any dispute, controversy, or claim arising out of or relating directly or indirectly to the [Skadden] settlement.” Instead, relying on Kokkonen v. Guardian Life Ins. Co.,
In reaching this conclusion, the Court noted that “[t]he situation would be quite different if the parties’ obligation to comply with the terms of the settlement agreement had been made part of the order of dismissal — either by separate provision (such as a provision ‘retaining jurisdiction’ over the settlement agreement) or by incorporating the terms of the settlement agreement in the order.” Id. In such a case, the Court noted, “a breach of the agreement would be a violation of the [court’s] order.” Id. And under the familiar principle that a court has ancillary jurisdiction “relating to the court’s power to protect its proceedings and vindicate its authority,” id. at 380,
Kokkonen thus establishes the straightforward principle that in order for a federal court to retain ancillary jurisdiction to enforce a settlement agreement, the retention of that jurisdiction must serve or connect to a prior legitimate exercise of the court’s authority. And this idea reveals why the two propositions Herrick advances — (1) that the district court could exercise supplemental jurisdiction over the settlement agreement, and (2) that this
First, the district court’s exercise of continuing jurisdiction over the settlement involving Skadden depends on the district court’s prior exercise of jurisdiction over the lawsuit involving Skadden. Where, as here, there was no proper federal jurisdiction over the initial lawsuit, the reason by reference to which Kokkonen justifies the exercise of supplemental jurisdiction over the settlement — the vindication of the court’s prior authority — falls away. Because there is no properly exercised prior authority to vindicate, the district court necessarily erred in retaining jurisdiction over the settlement.
Second, the district court’s mistake in retaining jurisdiction over the settlement cannot be isolated from the remainder of the lawsuit, precisely because that jurisdiction depends on the district court’s mistaken assertion of subject matter jurisdiction (of authority) over the settled disputе. The assertion of supplemental jurisdiction over the settlement, precisely because it involves no independent jurisdictional basis separate from the original dispute, must be understood to imply an assertion of continued involvement in and jurisdiction over that original dispute. Accordingly, the jurisdictional defect caused by Skadden’s inclusion as a defendant remains in place^ — and continues to destroy federal jurisdiction over the original suit— right up through the present day.
Finally, this conclusion is in keeping with the firm rule, articulated in Kroger and affirmed by 28 U.S.C. § 1367(b), that assertions of ancillary jurisdiction may not be used to avoid the requirement of complete diversity expressed in 28 U.S.C. § 1332. This requirement is imposed on the “original jurisdiction” of the federal district courts, 28 U.S.C. § 1332(a), that is, not only on the final decision-rendering capacity of these courts, but also on every exercise of their judicial power. If problems of incomplete diversity could be cured simply by allowing plaintiffs to settle with non-diverse defendants subject to the continuing jurisdiction of the district court, then plaintiffs could secure all the services of the federal courts' — -including the supervision of discovery, the issuance of partial summary judgment, and, perhaps most critically, the enforcement of settlements— in cases over which the federal courts do not have proper subject matter jurisdiction, so long as the plaintiffs did not require final decision-making by these courts. This result would, to a substantial degree, “allow the requirement of complete diversity to be circumvented” and “would simply flout the congressional command.” Kroger,
C. Curing Jurisdiction
If there are no facts sufficient to overcome SCS/Swid’s allegations that Skadden has jurisdiction-destroying, foreign-domiciled partners, then the federal courts cannot establish jurisdiction over the ease by means of the doctrine of supplemental jurisdiction. In this event, the inquiry must turn to the question of whethеr the continuing defect in federal jurisdiction may be cured. It is possible that such a cure is available. Cf. Squibb,
The existence of federal jurisdiction over a ease initially filed in federal court ordinarily depends on the facts as they stood when the complaint was filed. See, e.g., Smith v. Sperling,
The first of these exceptions, although completely straightforward, is not available in the case before us given the facts that have at this point been established. We have indeed held that an adequate pleading of diversity, rather than being itself a necessary element of diversity jurisdiction, is “merely an allegation informing the court that diversity jurisdiction independently exists.” Jacobs,
With respect to the second way of curing such defects, the Supreme Court, in Caterpillar, Inc. v. Lewis,
Neuman-Green does indeed give the appellate courts power to cure jurisdictional defects even on appeal, and this power is backed by weighty reasons. As the Supreme Court has remarked, “[o]nce a diversity case has been tried in federal court with rules of decision supplied by state law ... considerations of finality, efficiency, and economy become overwhelming.” Caterpillar,
Significantly, Newman-Green involved an appeal from a decision on summary judgment concerning defendants who were jointly and severally liable to the plaintiff. As a result, the Supreme Court noted, none of the diverse defendants could be prejudiced by a dismissal of the non-diverse defendant, see Newman-Green,
The facts of the case at bar, and the differences between the circumstances they present and those at issue in Newman-Given, make it much more diffiсult to conclude at the appellate level that jurisdiction may properly be salvaged in this case and require, instead, that the case be remanded to the district court for further findings. To begin with, while it was uncontested in Newman-Green that the diverse and nondiverse defendants would be jointly and severally liable for any damages the plaintiff recovered, in the case before us it is possible, and Herrick vigorously argues, that at least some of the damages paid by Skadden reflect claims Herrick could bring against Skadden alone, and therefore should not be set-off against the jury verdict that Herrick has obtained against SCS/Swid. Furthermore, whereas in Newman-Green, the judgment saved by creating jurisdiction nunc pro tunc was a summary judgment, that is, a judgment that would have to be agreed to by any reasonable jury, in the instant case, the judgment Herrick asks us to save is a verdict rendered by an actual jury that had for four days of trial seen SCS/Swid presented side-by-side with Skadden, described to the jury as “one of the largest, most powerful and sophisticated law firms in this country.”
In elaborating on the idea that prejudice caused by the presence of a non-diverse party might preclude salvaging jurisdiction in the manner of NewmanGfl'een, the Supreme Court noted that “[i]t may be that the presence of the nondiverse party produced a tactical advantage for one party or another.” Newman-Green,
In the case at bar, SCS/Swid claims that it has suffered prejudice as a result of Skadden’s inclusion in the lawsuit. Although these assertions may in the end turn out to be meritless, and although we do not, of course, adjudicate their merits here, we cannot dismiss them as frivolous. Accordingly, and in light of the Supreme Court’s admonition to caution, we remand the question of the existence of jurisdiction to the district court for further proceedings as described by Newman-Green.
This conclusion is not altered by the fact that SCS/Swid failed to raise the question of federal jurisdiction until after the jury had rendered its verdict. In this regard, the ease at bar must be distinguished from the line of cases founded on Grubbs v. General Electric Credit Corp.,
We believe that the Gmbbs holding is not so sweeping as the district court’s treatment of it suggested. In deciding Gmbbs, the Supreme Court emphasized that the district court properly had federal jurisdiction over the case at the time it entered its judgment. As a result, the issue in Grubbs was not the existence of federal jurisdiction, per se, but the propriety of the removal procedure employed. Indeed, the parties in Gmbbs conceded that original federal jurisdiction would have been present had the case been filed directly in federal court. Id. at 704,
In the case at bar, and in contrast to Grubbs, Herrick chose the federal forum in which to file its initial complaint, and SCS/Swid is not merely attacking a removal procedure but is instead challenging precisely what Grubbs assumed, namely that the pre-requisites for federal jurisdiction obtain. Under these circumstances, the fundamental principle that the limits on federal subject matter jurisdiction cannot be waived, and may be challenged at any time, governs. See Curley,
This does not mean, however, that delay in raising such a challenge may not be relevant to the question of whether the challenger can claim prejudice. Indeed, timeliness may well constitute a countervailing factor to the argument that the other party obtained a tactical advantage from the existenсe of improper jurisdiction. But that is, of course, a very different question from that of waiver or estoppel.
III. CONCLUSION
We hold that because Herrick has failed to establish specific domestic domiciles for Skadden’s partners from which SCS/Swid’s allegations of foreign domiciles might represent a departure, McNutt rather than Desmare governs this case. Accordingly the burden of persuasion concerning diversity rests with Herrick, the party asserting the subject matter jurisdiction of the federal courts. We also hold that Herrick has failed, on present evidence, to carry this burden, so that it must be assumed that Herrick and Skadden are not diverse and that there is no independent source of federal jurisdiction over Herrick’s lawsuit against Skadden. We conclude, therefore, that the district court could not properly exercise supplemental jurisdiction either over Herrick’s initial lawsuit against Skad-den or over the narrower subject matter of the settlement involving Skadden. We further hold that by asserting supplemental jurisdiction over the settlement, the district court has for jurisdictional purposes retained Skadden as a party to the lawsuit right through this appeal, so that the defect in federal subject matter jurisdiction caused by Skadden’s participation in the case perdures. Finally, we hold that although the federal courts may in appropriate instances cure jurisdictional defects of the type presented by Skadden (by dismissing jurisdictionally improper parties pursuant to Fed.R.Civ.P. 21), and may do so even on appeal, this power may be exercised by appellate courts only when the presence of the jurisdictional spoiler has clearly not prejudiced the remaining parties in the lawsuit.
Because we conclude that we cannot, on the facts of this case, determine whether or not SCS/Swid has been prejudiced by Skadden’s presence in the suit, we are unable to decide the ultimate jurisdictional question presented by the case ourselves but must instead remand the case to the district court for further consideration of this quеstion. And because we neither have jurisdiction over the case as it stands before us nor can cure the jurisdictional defect ourselves, we do not reach any of the parties’ remaining contentions on appeal.
Accordingly, the judgment below is VACATED and the case is REMANDED for further proceedings consistent with this opinion.
Notes
. The parties also made a series of further requests for summary judgment that are not relevаnt to the present appeal. Specifically, the business defendants asked for summary judgment dismissing the fraud claim against them; plaintiffs asked for summary judgment against Skadden on all claims; and Skadden asked for summary judgment dismissing the claims alleging that they had breached their fiduciary duty and that they substantially assisted the business defendants' breach of the Letter Agreement.
. In addition, the district court granted the business defendants’ motion for summary judgment dismissing the claim against them for fraud; denied plaintiffs’ motion for summary judgment against Skadden; denied Skadden’s motion for summary judgment dismissing the claim against them for breach of fiduciary duty; and granted Skadden's motion for summary judgment dismissing the claim against them for substantially assisting the business defendants' breach of the Letter Agreement.
. The district court explained these denials in a Revised Opinion and Order filed on August 27.
. Although, as we have remarked, we are "unclear as to Congress's rationale for not granting United States citizens domiciled abroad rights parallel to those it accords to foreign nationals, the language of § 1332(a) is specific and requires the conclusion that a suit by or against United States citizens domiciled abroad may not be premised on diversity.” Cresswell, 922 F.2d at 68.
. In Gutieirez, there was no question that the plaintiff's initial domicile was New Jersey, and the argument focused exclusively on whether it had been adequately established that the plaintiff had abandoned this domicile and established a new one in New York. See id..,
. This sort of jurisdiction had variously been called ancillary or pendent. “Traditionally, ancillary jurisdiction refers to joinder, usually by a party other than the plaintiff, of additional claims and parties added after the plaintiff's claim has been filed. It is mainly a tool for defendants and third parties whose interests would be injured if their jurisdictionally insufficient claims could not be heard in an ongoing action in federal court. Pendent jurisdiction traditionally refers to the joinder of a state-law claim by a party already presenting a federal question claim against the same defendant.” Baylis v. Marriott Corp.,
Given the complexities of the many manifestations of federal jurisdiction ... there is little profit in attempting to decide ... whether there are any “principled” differences between pendent and ancillary jurisdiction.
Aldinger v. Howard,
. The supplemental jurisdiction statute, 28 U.S.C. § 1367, also expressly recognizes the limil the requirement of complete diversity imposes on the scope of the supplemental jurisdiction the statute creates. Although as a general matter, § 1367 expands supplemental jurisdiction to all claims and all parties that are part of the same constitutional case over which there exists independent federal jurisdiction, see 28 U.S.C. § 1367(a), it retains, as one of several exceptions to this broad rule, the principle that in cases in which original federal jurisdiction is founded solely on diversity, there shall generally be no supplemental jurisdiction оver claims by plaintiffs against persons made parties under Fed.R.Civ.P. 14, 19, 20 or 24 "when exercising supplemental jurisdiction over such claims would be inconsistent with the jurisdictional requirements of section 1332,” including the requirement of complete diversity. See 28 U.S.C. § 1367(b). For an interesting discussion of the legislative history of § 1367 and of problems arising under this statute, see Christopher M. Fair-man, Abdication to Academia: The Case of the Supplemental Jurisdiction Statute, 28 U.S.C. § 1367, 19 Seton Hall Legis. J. 157 (1994).
.There do exist some precedents allowing supplemental jurisdiction even in cases in which complete diversity is lacking. See, e.g., Krippendorf v. Hyde,
. The parties disagree vigorously about when the settlement took effect, and consequently about when this approach to salvaging federal jurisdiction became available to Herrick.
. This reasoning is consistent with the Supreme Court's conclusion, in Caterpillar, Inc. v. Lewis,
. Similarly, allowing a settlement (that maintains the court's supervisory powers) to cure problems of incomplete diversity would have the effect of allowing the settling defendant to waive any objection to diversity jurisdiction and would therefore violate the prin
. At several other places in the Caterpillar opinion, the Supreme Court emphasized that the jurisdictional delect in that case had been cured "prior to trial,” or by "the time of trial and judgment,” or "before the trial commenced.” Id. at 67, 73,
We note, furthermore, that this conclusion saves us from having to address the complicated question, hotly disputed by the parties, of the proper application of the (possibly uncertain) Caterpillar rule to the (unquestionably confusing) circumstances of this case. In particular, we need not decide whether the involved procedural history of this case (the January 15 settlement announcement, February 25 entry of judgment, April 13 vacatur of that judgment, July 23 Stipulation and Order dismissing the settling parties, and August 12 entry of a new judgment as to the remaining parties) should be interpreted as creating a settlement before or after the entry of judgment.
. Indeed, in discussing the principle that where original federal jurisdiction over a case would have been proper, a defendant who has removed the action is estopped from protesting that there was no right to removal, Grubbs noted, citing American Fire & Casualty Co. v.
