This appeal concerns the power of the district court to permit certain Puerto Rican residents, who have sued the United States for the alleged negligence of a Veterans Hospital, to add to their complaint a nonfederal tort claim
1
against Hospital Mimiya, Inc., a private institution in Puerto Rico. By the time of the proposed amendment, Hospital Mimiya had been brought into the litigation as a third-party defendant by the United States, which claimed a right of indemnification from Mimiya should the United States be found liable. The district court refused to allow plaintiffs to amend their complaint so as to sue Hospital Mimiya directly, and denied their motion for reconsideration, stating that it lacked power to exercise either ancillary or pendent jurisdiction over the proposed non-federal claim against Hospital Mimiya.

We hold that statutory considerations do not bar “the exercise of jurisdiction over the particular nonfederal claim” involved herein,
see Owen Equipment and Erection Co. v. Kroger,
I.
Upon exhausting their administrative remedies, 28 U.S.C. § 2675, Ramonita Ortiz, et al. (hereinafter appellants) sued the United States under the Federal Tort Claims Act, 28 U.S.C. §§ 1346(b), 2671-80, 3 alleging that on January 21, 1973 appel *67 lants’ decedent was taken to the Veterans Hospital in San Juan where the employees and agents of that hospital, “failing to diagnose the seriousness of the condition, did not hospitalize or treat him, but at his wife’s insistence, referred him to Mimiya Clinic for hospitalization with a diagnosis of ‘malaria attack.’ ” Thereafter he allegedly was not given proper treatment and by the time, three days later, that he was returned to the V.A. Hospital he had allegedly sustained “permanent, irreparable damage.” Appellants also contend that the V.A. Hospital’s “referral [to Mimiya] was an authorization for admission under Veterans Administration’s instructions.” The decedent, in any event, steadily declined until he died one and one-half years later.
After suit was brought, the United States filed a third-party complaint against Hospital Mimiya seeking indemnification. This complaint, although it failed to make mention of the fact, was bottomed on an independent federal jurisdictional basis, 28 U.S.C. § 1345.

Thereafter, appellants unsuccessfully sought leave of court to amend their own complaint to add a negligence claim directly against Mimiya. After denying the motions to amend and for reconsideration, the district court granted appellants permission, to which we assented, to bring an interlocutory appeal, 28 U.S.C. § 1292(b), from these orders. We stayed consideration of the appeal pending the United States Supreme Court’s decision in
Qwen Equipment and Erection Co. v. Kroger,
which issued last June,
While when
Kroger
was first called to our attention it seemed as if it might be controlling, it is now clear that its underlying facts differ significantly from those before us. In
Kroger,
plaintiff, a citizen of Iowa, sued defendant, a citizen of Nebraska, under the diversity statute (there were no federal claims as such). After filing a third-party complaint against Owen Equipment and Erection Company, defendant moved for summary judgment on plaintiff’s claim against it. While this motion was pending, plaintiff successfully moved to amend its complaint to add a claim against Owen. Summary judgment was thereafter rendered in defendant’s favor on the original claims, leaving only plaintiff’s claim against Owen to proceed to trial. On the third day of trial, Owen moved to dismiss for lack of subject matter jurisdiction on the ground that it was a citizen of the same state as plaintiff. The district court denied the motion and was affirmed on appeal. The Eighth Circuit reasoned that in light of
United Mine Workers v. Gibbs,
The Court said that there are two “hurdle[s] that must be overcome in determining that a federal court has jurisdiction over a particular controversy. For the jurisdiction of the federal courts is limited not only by the provisions of Art. Ill of the Constitution, but by Acts of Congress.”
Kroger,
The Kroger analysis is not dispositive here since the present case was not brought under the diversity statute but rather under the Federal Tort Claims Act. Furthermore, Hospital Mimiya’s status in the case is different from Owen’s, as it is a third-party defendant under a federal jurisdictional statute. These factors point to a different analysis and, ultimately we believe, a different result, from Kroger.
In deciding whether the district court erred in ruling that it lacked judicial power to hear appellants’ claim against Hospital Mimiya, we first consider whether jurisdiction is precluded by Article III. While this question was bypassed in
Kroger,
it remains — as the
Kroger
Court acknowledged — one of two fundamental “hurdles,” both of which must be cleared for jurisdiction to exist.
Gibbs,
“Pendent jurisdiction, in the sense of judicial power, exists whenever there is a claim ‘arising under [the] Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority . . .,’ U.S.Const., Art. Ill, § 2, and the relationship between that claim and the state claim permits the conclusion that the entire action before the court comprises but one constitutional ‘case.’ The federal claim must have substance sufficient to confer subject matter jurisdiction on the court. Levering & Garrigues Co. v. Morrin,289 U.S. 103 , [53 S.Ct. 549 ,77 L.Ed. 1062 ]. The state and federal claims must derive from a common nucleus of operative fact. But if, *69 considered without regard to their federal or state character, a plaintiff’s claims are such that he would ordinarily be expected to try them all in one judicial proceeding, then, assuming substantiality of the federal issues, there is power in federal courts to hear the whole.”
One possible distinction between
Gibbs
and the present case is that
Gibbs
involved a “[cjase . . . arising under the Laws of the United States.” It is by no means clear that Federal Tort Claims Act actions are “[c]ase[s] . . . arising under . the Laws of the United States.” More likely, they arise under the portion of Article III authorizing federal court jurisdiction in “[cjontroversies to which the United States shall be a Party.”

See
note 5,
supra.
Should the
Gibbs
standards for determining when pendent jurisdiction is barred by Article III be applied where the federal question raises a “controversy,” as opposed to a “case”? This question was left unanswered by the majority in
Kroger,
which stated with respect to the Eighth Circuit’s application of the
Gibbs
standards to the “controversy” (between citizens of different states;
see
note 5, supra) before it that “[w]e may assume without deciding that the Court of Appeals was correct in this regard.”
There is some authority for the proposition that “[tjhe term ‘controversies,’ if distinguishable at all from ‘cases,’ is so in that it is less comprehensive that the latter, and includes only suits of a civil nature.”
Aetna Life Insurance Co. v. Haworth,
But we see little merit in this approach. Justice Iredell’s opinion in
Chisholm v. Georgia,
Commentators maintain that nothing has ever been made of the suggestion that controversies are less comprehensive than cases. 13 Wright, Miller & Cooper,
Federal Practice & Procedure
§ 3529 at 147 (1975). In any event, the suggested distinction nei
*70
ther arose nor has been applied in analyzing the permissible scope of pendent jurisdiction,
7
so even if for some purposes controversies should be viewed as being “less comprehensive” than cases, there is no precedent that they should be so viewed for pendent jurisdiction purposes. There is, moreover, some precedent for applying the
Gibbs
standards to “controversies.” The dissenters in
Kroger
did so, albeit without binding themselves to this approach in the future.
A second difference between
Gibbs
and the present action is that plaintiff’s federal and nonfederal claims in
Gibbs
were both against the same party, while here plaintiffs’ federal claim is against the United States, and their nonfederal claim is against Hospital Mimiya. This difference could have been critical had Mimiya been brought into the case solely as a consequence of appellants’ nonfederal claim against it.
Moor v. County of Alameda,
We, too, need not reach the difficult question whether the district court would have power under Article III to join a non-federal party as well as hear a nonfederal claim.
See Aldinger,
Having decided, despite differences between
Gibbs
and the present case, that
Gibbs
provides the correct measure for determining if Article III allows the district court to hear appellants’ nonfederal claim against Hospital Mimiya, we next turn to the application of the
Gibbs
standards. It was held in
Gibbs
that a district court has power under Article III to hear a nonfederal claim if that claim and the federal claim derive from a common nucleus of operative fact and if the federal claim is of sufficient substance to confer jurisdiction on the court. These are the tests that must be met here for Article III jurisdiction to exist. Whether appellants’ claim against the United States based on the purported negligence of personnel at the V.A. Hospital is of sufficient substance to confer jurisdiction under the Federal Tort Claims Act depends upon whether the conduct alleged is conduct for which “a private person, would be liable . in accordance with the law of the place where the act or omission occurred.” 28 U.S.C. § 1346(b). As that issue, which requires reference to the local law of Puerto Rico, has not been briefed or argued, we do not decide it, but refer it to the district court upon remand. The same is true of the interrelated question whether appellants’ claims derive from a common nucleus of operative fact. Both must be resolved in plaintiffs’ favor for the court to have jurisdiction under Article III. Should the court rule in plaintiffs’ favor on both questions, this will not end matters: the district court will still retain discretion to decide whether or not to exercise pendent jurisdiction over the nonfederal claim,
see Gibbs,
Having gone as far as we can with respect to Article III, we now turn to the second hurdle which must be cleared in order to find pendent jurisdiction over the claim against Hospital Mimiya. The Supreme Court has said that beyond the “constitutional minimum,” i. e., compliance with Article III,
“there must be an examination of the posture in which the nonfederal claim is asserted and of the specific statute that confers jurisdiction over the federal claim [here, the Federal Tort Claims Act] in order to determine whether ‘Congress in [that statute] has . . . expressly or by implication negated’ the exercise of jurisdiction over the particular nonfederal claim.”
Kroger,
*72
The “posture” of appellants’ claim against Hospital Mimiya is as follows. As in
Kroger,
appellants’ claim against the third-party defendant, Hospital Mimiya, is not ancillary to their claim against the United States in the sense of being dependent upon the outcome of that claim. The claim against Hospital Mimiya is separate and independent. This fact distinguishes the instant case from the cases in which ancillary jurisdiction is most commonly exercised.
See Kroger,
Unlike the situation in
Kroger,
however, appellants’ claim against the United States must be brought in a federal court. 28 U.S.C. § 1346(b). If appellants are barred from suing Hospital Mimiya in the instant suit, they will be forced to pursue their claims against the government and Hospital Mimiya in separate forums, one federal and one state. We are not faced with a situation where “ ‘the efficiency plaintiff seeks so avidly is available without question in the state courts.’ ”
Kroger,
“When the grant of jurisdiction to a federal court is exclusive, for example, as in the prosecution of tort claims against the United States under 28 U.S.C. § 1346, the argument of judicial economy and convenience can be coupled with the additional argument that only in a federal court may all claims be tried together.”
Aldinger,
A final point bearing on the “posture” of the nonfederal claim is that Hospital Mimi-ya is not being dragged into the case solely as a result of this claim. As we have already discussed, Hospital Mimiya is in the litigation because of the government’s third-party complaint, based upon an independent ground of federal jurisdiction, 28 U.S.C. § 1345. A nonfederal claim against a party who would not otherwise be in the action would present “a more serious obstacle to the exercise of pendent jurisdiction than if parties already before the court are required to litigate a state law claim.”
Aldinger,
Having described what
Kroger
calls the “posture” of appellants’ claim against Hospital Mimiya, we turn to an analysis of the “specific statute that confers jurisdiction,” namely the Federal Tort Claims Act, “to determine whether ‘Congress in [that statute] has . . . expressly or by implication negated’ the exercise of jurisdiction over the particular nonfederal claim” before us.
Kroger,
Unlike the diversity statute, which has been construed restrictively,
Kroger,
Given the posture of appellants’ claim against Hospital Mimiya, considerations of judicial economy, convenience and fairness to [the parties], the policies upon which the doctrine of pendent jurisdiction is founded,
Kroger,
We hold, therefore, that the district court is not barred by statutory considerations from exercising pendent jurisdiction over appellants’ nonfederal claim against Hospital Mimiya. We leave it for the district court, however, to decide on remand whether in this case there is sufficient compliance with the
Gibbs
criteria to meet Article III requirements. If the court should so find, it should then decide, as a matter of sound discretion, whether it is advisable for it to exercise its power over the nonfederal claim.
Gibbs,
Reversed and remanded for further proceedings consistent with this opinion.
Notes
.. We use the term “ ‘nonfederal claim’ to mean one as to which there is no independent basis for federal jurisdiction. Conversely, a ‘federal claim’ means one as to which an independent basis for federal jurisdiction exists.”
Owen Equipment and Erection Co. v. Kroger,
. As in
Kroger,
it is not “necessary to determine here ‘whether there are any “principled” differences between pendent and ancillary jurisdiction . . .
. The Federal Tort Claims Act states in part, “§ 1346. United States As Defendant.
(b) the district court shall have exclusive jurisdiction of civil actions on claims against the United States, for money damages, . . for injury or loss of property, or personal injury or death *67 caused by the negligent or wrongful act or omission of any employee of the Government while acting within the scope of his office or employment, under circumstances where the United States, if a private person, would be liable to the claimant in accordance with the law of the place where the act or omission occurred.
“§ 2674. Liability of United States.
The United States shall be liable, respecting the provisions of this title relating to tort claims, in the same manner and to the same extent as a private individual under like circumstances, but shall not be liable for interest prior to judgment or for punitive damages.
If, however, in any case wherein death was caused, the law of the place where the act or omission complained of occurred provides, or has been construed to provide, for damages only punitive in nature, the United States shall be liable for actual or compensatory damages, measured by the pecuniary injuries resulting from such death to persons respectively, for whose benefit the action was brought in lieu thereof.”
. “§ 1345. United States as Plaintiff.
Except as otherwise provided by Act of Congress, the district court shall have original jurisdiction of all civil actions, suits or proceedings commenced by the United States, or by any agency or officer thereof expressly authorized to sue by Act of Congress.”
. U.S.Const., art. Ill, § 2, cl. 1, states:
“The judicial Power shall extend to all Cases, in Law and Equity, arising under this *68 constitution, the Laws of the United States, and Treaties made, or which shall be made under their authority; — to all Cases affecting Ambassadors, other public Ministers and Consuls; — to all Cases of admiralty and maritime Jurisdiction; — to Controversies to which the United States shall be a Party; — to Controversies between two or more States; — between a State and Citizens of another State; —been Citizens of different States; — between Citizens of the same States claiming Lands under Grants of different States, and between a State, or the Citizens thereof, and foreign States, Citizens or Subjects.”
. The plurality in
Glidden Co. v. Zdanok,
. The suggested difference between “cases” and “controversies” originated and has traditionally been referred to, in the context of determining whether a question or dispute presented to a court is justiciable. 13 Wright, Miller & Cooper, Federal Practice & Procedure § 3529 at 147-49 (1975).
. The district court based its holding that it lacked power to hear appellants’ claim against Mimiya on the ground that it did not have the power under Article III to do so and cited to
Moor,
In
Ayala,
as in
Moor,
the parties against whom the nonfederal claims were raised would not have been a party to the suit but for the nonfederal claims. Therefore, it too is distinguishable from the present case. Furthermore, the holding in
Ayala,
that the exercise of pendent jurisdiction was barred by constitutional considerations, was based on a case,
Kataoka v. May Department Stores Co.,
. Based upon its reading of Gibbs, Aldinger, and Kroger, .the government argues that in the present case we need not consider whether Congress has manifested an intent that jurisdiction not be exercised over the nonfederal claim, only whether Article III bars such jurisdiction. The government contends that congressional intent need only be considered in “pendent party” cases, which it defines as those actions in which the plaintiff desires to raise a nonfederal claim against a person who is not already a party as the result of a federal claim pending against him. The present case is a “pendent claim” action, according to the *72 government, because appellants wish to assert a nonfederal claim against a party, Hospital Mimiya, against whom a federal claim (the third party complaint) is pending.
While the approach advocated by the government may seem reasonable in light of Gibbs and Aidinger, we think our approach may be the correct one when Kroger is taken into account. In Kroger the Court advocated consideration of both Article III and congressional intent without attempting to classify the case before it as being either a pendent party or a pendent claim action.
In any event we decline to reach the issue as to which of these two approaches constitutes the correct reading of the Gibbs-Aldinger-Kroger trilogy because under either approach our decision concerning the district court’s right to exercise jurisdiction over the nonfederal claim in the present case would be the same.
