Gloria Rodas’s appeal presents an important question about the meaning of a provision of the Illinois Good Samaritan Act, 745 ILCS 49/1 et seq., in a case that was removed to federal court under the federal officer removal statute, 28 U.S.C. § 1442. The state-law question is whether and under what circumstances the protections of the Good Samaritan Act turn on the business model physicians use to charge patients for emergency services. The law shields from liability physicians who render certain services “without fee.” Rodas was charged a fee for the services she received, but two of Rodas’s physicians were not paid from that fee. Instead, they received a salary from their medical practice. The district court agreed with the defendants that the salary-versus-fee distinction cloaked the physicians with statutory immunity. Rodas appeals.
The United States, a party to the underlying action but not to this appeal, has filed a brief as amicus curiae urging that we lack jurisdiction. The argument is that the doctrine of derivative jurisdiction created a latent jurisdictional defect that persists on appeal. The doctrine provides that a federal court acquires no jurisdiction upon removal where the state court lacked jurisdiction over the subject matter or the parties. That principle, the government maintains, robbed the district court of subject matter jurisdiction and deprives us of appellate jurisdiction.
We disagree with both the government’s position about our jurisdiction and the defendants’ interpretation of the Illinois statute. As to jurisdiction, we join every other circuit to have considered the question and hold that the doctrine of derivative jurisdiction is cabined by the principles announced in
Grubbs v. Gen. Elec. Credit Corp.,
I. Background
In 2001, Gloria Rodas had been receiving prenatal care at the Crusaders Central Clinic Association (“Crusader Clinic”) in Rockford, Illinois. The Crusader Clinic is a community health center and recipient of federal funds under 42 U.S.C. § 254b. Doctor William Baxter was one of the physicians who provided care; he was a family practice physician and clinic employee. In a limited sense, however, Baxter had two masters: because of the relationship between the Crusader Clinic and the federal government, both the clinic and Baxter were deemed to be employees of the United States for purposes of medical malpractice liability.
See
42 U.S.C. § 233(g)-(n). As a consequence of Baxter and the Crusader Clinic’s (deemed) federal status, the United States could be substituted as a party if either were ever sued. 28 U.S.C. 2679(d)(1). Claims against them would be governed by the Federal Tort Claims Act, and neither would face liability.
See
28 U.S.C. § 2679(b)(1);
Osborn v. Haley,
Baxter was not the only physician providing care to Rodas and other Crusader Clinic patients. For medically complex situations, the Crusader Clinic contracted with the University of Illinois College of Medicine (“UIC”) to provide specialist services. The arrangement called for UIC obstetrician/gynecologists to provide care at the Crusader Clinic, to provide on-call backup to clinic doctors, and to be on call when clinic patients were treated at local hospitals. In exchange, the Crusader Clinic paid UIC a fixed amount each year. The UIC physicians would fill out billing forms for their work and submit them to the Crusader Clinic; the Crusader Clinic had the right to collect the fees.
The two salaried UIC physicians implicated in this appeal are Doctor Ana-Maria Soleanicov and Doctor John Seidlin. Unlike Baxter, they were not deemed to be employees of the United States, and so they generally faced the specter of individual liability for any medical malpractice they committed. The alleged malpractice in this case occurred on August 2, 2001. During that day’s pre-dawn hours, Rodas went into labor. Following previously provided instructions from the Crusader Clinic, she went to the delivery floor at Swedish American Hospital. There, she was seen by a UIC resident until Baxter — our deemed federal employee — arrived at the hospital. Baxter took over care for Rodas, along with another UIC resident. Baxter’s understanding was that Soleanicov and Seidlin would be available to assist if needed. And they were needed, because Rodas’s delivery became an emergency. After about eight hours of labor, the baby’s heart tones had dropped, Rodas was not pushing effectively, and the baby was not descending. Soleanicov and Seidlin arrived to provide assistance. After multiple unsuccessful attempts to deliver the baby using a vacuum extractor and then forceps, Andrea Rodas was delivered via Cesarean section. She would not live very long. Less than two weeks later, she died from hypoxic ischemic encephalopathy, a condition in which the brain does not receive sufficient oxygen. Soleanicov prepared a bill for her work. Seidlin, deviating from his common practice, did not. The Crusader Clinic was reimbursed for the services Soleanicov provided.
Gloria Rodas filed a tort suit in state court in 2003, naming as defendants Baxter, Soleanicov, Seidlin, the Crusader Clinic, and Swedish American Hospital. The complaint alleged that the defendants negligently managed Rodas’s labor in a variety of ways, resulting in Andrea’s death. The United States removed the case to federal court, substituting itself as a party in place of the Crusader Clinic and Baxter. See 42 U.S.C. § 233(c) (removal); 28 U.S.C. § 2679(d)(1) (substitution). Because the action was against the United States and could proceed only under the Federal Tort Claims Act, see 28 U.S.C. § 2679(b)(1), Rodas was required to seek relief directly from the appropriate federal agency before filing suit, 28 U.S.C. § 2675(a). Therefore, she voluntarily dismissed her claims against the United States and the remainder of the case was remanded to state court. Rodas v. Swedish Am. Health Sys. Corp., 3:03-cv-50483, ECF No. 4 (N.D.Ill. Nov. 19, 2003). Rodas then filed an administrative claim with the United States Department of Health and Human Services.
The agency denied Rodas’s claim for damages, ruling that she had not established that the death of Andrea was caused by a negligent act or omission of a federal employee acting within the scope of em *614 ployment. The letter informed Rodas that, if dissatisfied with the determination, she could appeal within the agency hierarchy or file suit against the United States “in the appropriate federal district court within six (6) months from the date of mailing this determination (28 U.S.C. § 2401(b)).” Rodas, however, did not seek to return to federal court.
Instead of returning to federal court, Rodas amended her state-court complaint against Swedish American Hospital, Soleanicov, and Seidlin. And instead of re-adding Baxter and the Crusader Clinic as defendants to that complaint, she named the United States directly (along with Soleanicov and Seidlin). The United States again removed the case to federal court, this time invoking in its notice of removal the federal officer removal statute, 28 U.S.C. § 1442. Section 1442(a)(1) provides that a “civil action ... commenced in a State court” may be removed to federal court if the action is against “[t]he United States or any agency thereof or any officer (or any person acting under that officer) of the United States or of any agency thereof, sued in an official or individual capacity for any act under color of such office.... ” After removal, the case proceeded through the motion to dismiss phase and discovery was taken. By the time defendants Seidlin and Soleanicov separately moved for summary judgment in June 2008, the case’s second life in federal court was more than three years old.
Seidlin and Soleanicov filed their summary judgment motions in late May and early June 2008. Both contended that they were shielded from liability by the Illinois Good Samaritan Act provision governing emergency care. The Act shields from liability physicians “who, in good faith, provide[] emergency care without fee to a person.” 745 ILCS 49/25. The district court agreed that Soleanicov and Seidlin fell within the Act’s ambit because fees from Crusader Clinic patients did not go directly to them. Expanding on dicta from the Illinois Appellate Court’s decision in
Estate of Heanue v. Edgcomb,
After judgment in favor of Soleanicov and Seidlin was entered, the United States moved to dismiss the case, contending that the doctrine of derivative jurisdiction deprived the court of subject matter jurisdiction over the case. The district court entered an indicative ruling, Fed.R.Civ.P. 62.1(a), denying the government’s motion. (The case against the United States proceeds below.) The district court reasoned that although the doctrine of derivative jurisdiction applies to removals under the federal officer removal statute, the government had not properly removed on that basis. In fact, removal had been effected under 28 U.S.C. § 2679(d)(2) and 42 U.S.C. § 233(c).
Rodas v. SwedishAm. Health Sys. Corp.,
In response to the district court’s ruling, the United States filed a brief with us as a friend of the court, raising the alleged jurisdictional defect. The parties have responded to the government’s arguments in their merits briefs, generally echoing the district court’s reasoning.
II. Discussion
Summary judgment rulings, like matters of subject matter jurisdiction, are subject to de novo review.
Kaplan v. United States,
Proceeding to the merits, the defendants misread the language of the Illinois Good Samaritan Act and overstate the implications of the Illinois Appellate Court’s decision in
Heanue.
Doctor Soleanicov rendered her emergency services for a fee and thus does not enjoy statutory immunity under the Good Samaritan Act. Although Seidlin did not charge a fee, there is a genuine issue of material fact about whether he did so in “good faith,” a predicate to the Act’s liability shield.

745 ILCS 49/25;
Heanue,
A. (Derivative) Jurisdiction
Before reaching the merits of this appeal, we must address a jurisdictional issue the United States has raised. When a case is removed from state to federal court, the jurisdiction of the latter is said “in a limited sense” to derive from the former.
Edwards v. United States Dep’t of Justice,
The government’s argument can be succinctly summarized: By its terms the doctrine of derivative jurisdiction applies to this case. Rodas commenced her action against the United States in state court, but federal sovereign immunity deprived the state court of subject matter jurisdiction.
See Hercules, Inc. v. United States,
The government’s argument has considerable surface appeal, and most of it is without flaw. For our purposes, the only questions are (1) whether removal was proper under Section 1442, such that the doctrine of derivative jurisdiction applies; and (2) whether the doctrine of derivative jurisdiction creates a defect in subject matter jurisdiction that evades the teachings of Grubbs and Caterpillar. We take up each question in turn.
1. Federal officer removal and the doctrine of derivative jurisdiction.
Removal under 28 U.S.C. § 1442(a)(1) was proper. Section 1442 is known as the federal officer removal statute. Section 1442(a)(1) provides that “[a] civil action commenced in a State court against ... [t]he United States or any agency thereof or any officer (or any person acting under that officer) of the United States or of any agency thereof, sued in an official or individual capacity for any act under color of such office” may be removed to federal court. The provision is an exception to the “well-pleaded com
*617
plaint” rule, which provides that for non-diversity cases to be removable, the complaint must establish that the case arises under federal law.
Kircher v. Putnam Funds Trust, 547
U.S. 633, 644 n. 12,
At the outset, we observe that the United States generally has the authority to invoke Section 1442(a)(1). When the modern version of the statute was enacted in 1948, it originally allowed for removal only by federal officers themselves. That was the holding of
Int’l Primate Protection League v. Admins, of Tulane Educ. Fund,
The district court concluded that timing is everything under Section 1442 and that the United States could not invoke the provision because it was not originally named as a defendant in the state-court complaint. We disagree with the district court’s analysis. The district court attached temporal significance to the proviso that Section 1442(a)(1) applies to a “civil action ... commenced in a State court against ” the United States (emphasis added). Here, the case was filed in state court, naming only individuals, removed to federal court, and then remanded to state court. Only then was the complaint amended to add the United States as a defendant.
We do not accept the district courts’s construction of Section 1442(a)(1) for several reasons. First, it requires an unorthodox reading of the provision to conclude that Congress was focused on the identity of named defendants at the time the state suit was commenced; the most natural reading of Section 1442 is that Congress was concerned
where
the civil action originated. Several other removal provisions also indicate, sensibly if not always in consistent language, that they apply to actions that start out in state court.
See
28 U.S.C. §§ 1441(a), 1443, 1444. Had Congress intended to focus on the identity of parties at the time the suit was filed, it would have been simple enough for it to do so.
Hamilton v. Lanning,
— U.S. -,
*618
The district court’s interpretation of Section 1442 is further weakened by the structure of Chapter 89 of Title 28, United States Code, which contains Section 1442 and several other provisions relating to removal. A separate provision in Chapter 89 already specifies the proper course to follow when an action that is not initially removable subsequently satisfies the criteria for removability. Specifically, 28 U.S.C. § 1446(b) provides: “If the case stated by the initial pleading is not removable, a notice of removal may be filed within thirty days after receipt by the defendant ... of a copy of an amended pleading....”
See also Caterpillar,
Finally, our reading of the text and structure of the Act are confirmed by Section 1442’s purpose and history. The Supreme Court has often stated that the policy behind the federal removal statute — ensuring that federal defenses raised by federal actors are evaluated in a federal forum — “should not be frustrated by a narrow, grudging interpretation” of the provision.
Willingham,
In sum, the purpose and history of the statute confirm what its text and structure tell us and counsel against the district court’s interpretation of Section 1442. As to the doctrine of derivative jurisdiction, the parties agree that it applies to removals under this provision. The doctrine provides a background rule against which all of the removal statutes operate; it applies unless abrogated.
See Palmer,
Having determined that the preconditions for removal under Section 1442(a)(1) were satisfied and that the doctrine of derivative jurisdiction applies to such removals, the next question is whether the doctrine is subject to limiting principles.
2. Limitations on the doctrine derivative jurisdiction.
The doctrine of derivative jurisdiction, despite its perhaps improvident name, is best understood as a procedural bar to the exercise of federal judicial power. That is, the doctrine creates a defect in removal, but is not an essential ingredient to federal subject matter jurisdiction. Because the district court would have had jurisdiction over a hypothetical complaint filed at the time it entered the judgment now under review, the fact that the state court lacked jurisdiction over the case when it was removed has no significance. To explain these conclusions, a word about the principles announced in Grubbs and Caterpillar is in order.
In
Grubbs,
the Supreme Court held that where a district court had “jurisdiction of the parties at the time it entered judgment ... the validity of the removal procedure followed may not be raised for the first time on appeal.”
*620
On appeal, the Fifth Circuit held that the priority of the United States’ judgment lien against Grubbs provided a “spurious” basis for removal under 28 U.S.C. § 1444. Because removal had not been authorized, the Fifth Circuit concluded that there was no other basis for the district court’s jurisdiction over the action and the cause had to be remanded to state court. The Supreme Court reversed. It did not take issue with the appellate court’s fix on the removal provision at issue but concluded that it had no bearing on the appeal. “Long-standing decisions of this Court make clear ... that where after removal a case is tried on the merits without objection and the federal court enters judgment, the issue in subsequent proceedings on appeal is not whether the case was properly removed, but whether the federal district court would have had original jurisdiction of the case had it been filed in that court.”
Grubbs,
In concluding that jurisdiction was proper on appeal, the court relied on its earlier teachings from
Baggs v. Martin,
The Supreme Court subsequently extended the rule in
Grubbs
to a situation in which the district court lacked subject matter jurisdiction at the time of removal because the parties were not completely diverse.
Caterpillar Inc. v. Lewis,
Like
Grubbs,
the Court’s opinion in
Caterpillar
distinguishes between procedural defects in removal on the one hand, which generally must be raised within 30 days,
see
28 U.S.C. § 1447(c) (motion to remand on basis other than lack of subject matter jurisdiction must be made within 30 days), and defects related to the Court’s subject matter jurisdiction. If a procedural defect in removal is cured by the time a judgment is entered, then practical concerns — finality, efficiency, and economy — militate in favor of retaining jurisdiction on appeal.
See also Korea Exch. Bank, New York Branch v. Trackwise Sales Corp.,
Put simply, if the doctrine of derivative jurisdiction constitutes a mere defect in the process by which a case reaches federal court, then this court may continue to exercise jurisdiction on appeal because the district court would have had original jurisdiction.
2
If, on the other hand, the derivative jurisdiction doctrine creates a latent and persistent defect in the subject matter jurisdiction of federal courts, then the issue can be raised at any time by any one.
E.g., Capron v. Van Noorden,
Admittedly, grappling with the procedure-versus-subject-matter-jurisdiction question is challenging because the doctrine of derivative jurisdiction is itself difficult to explain as a matter of first principles. The argument is also difficult to evaluate because the doctrine does not fit cleanly into the classifications that
Grubbs
and
Caterpillar
discuss. Both cases anticipate that procedural defects will relate to statutory requirements for removal.
See
After examining the issue, we reject the argument that the doctrine of derivative jurisdiction constitutes an essential ingredient of federal subject matter jurisdiction over removed actions. To be sure, the argument enjoys superficial appeal based on the name and language of the doctrine, and at least a handful of authorities explicitly describe derivative jurisdiction in subject matter jurisdiction terms.
Philadelphia & Reading Ry. Co. v. Sherman,
230 F.
814, 816 (2d
Cir.1916);
Crowley v. S.Ry. Co.,
Nonetheless, it would be too easy to unquestioningly accept a handful of lower court authorities as conclusive merely because they incant the words “subject matter jurisdiction.” The Supreme Court has long warned, even as it confesses occasional complicity, that courts are too quick to affix the “jurisdiction” label.
Compare Henderson ex rel. Henderson v. Shinseki,
- U.S. -,
The argument that the doctrine of derivative jurisdiction strikes at the heart of subject matter jurisdiction suffers from numerous flaws. At the outset, the textual allure of the jurisdictional argument is not so strong as it at first appears. While the doctrine says federal jurisdiction is derived from state courts, it in the same breath delivers its caveat that this is true only “in a limited sense.”
Lambert Run,
Therefore, it is not surprising that federal courts have regularly considered the doctrine of derivative jurisdiction as relating to “removal jurisdiction.”
Palmer,
Thus, the received understanding of the doctrine seems to place it on the procedural side of the
Grubbs
line. “[A] ‘procedural’ defect is any defect that does not go to the question of whether the case originally could have been brought in federal district court.”
Baris v. Sulpicio Lines, Inc.,
More critically, subject matter jurisdiction is unyielding,
Arbaugh,
The discussion in
Fidelity Trust
also shows that, unlike the time-of-filing rule at issue in
Grupo Dataflux,
the derivative jurisdiction rule is not based on the court’s constitutional authority to adjudicate a claim.
See also Bidwell,
*625
Conceiving of derivative jurisdiction as a procedural defect rather than a subject matter jurisdiction ingredient is consonant with
Freeman v. Bee Mach. Co.,
The foregoing analysis demonstrates that the doctrine of derivative jurisdiction, notwithstanding its perhaps improvident name, is a procedural bar to the exercise of federal judicial power. It is not an essential ingredient for a court’s subject matter jurisdiction. Therefore the principles of
Grubbs
apply. Unfortunately, the government’s brief did not wrestle with the questions we have considered, instead merely asserting that
Grubbs
does not apply to jurisdictional defects. That presumably is why the government did not inform us that circuits appear to be unanimous in holding that the doctrine of derivative jurisdiction is cabined by the principles announced in
Grubbs. See Morda,
nally been filed there, because there was no other bar to federal jurisdiction at the time of judgment, and because plaintiff never objected to subject matter jurisdiction at any time before or during the three-week trial below, the lack of derivative jurisdiction at the time of removal is irrelevant.”);
Foval v. First Nat’l Bank of Commerce in New Orleans,
We conclude that because the district court would have had jurisdiction over a hypothetical complaint filed at the time it entered the judgment now under review, the fact that the state court lacked jurisdiction over the case when it was removed has no significance. We proceed to the merits.
B. The Illinois Good Samaritan Act
We review de novo the district court’s decision to grant summary judgment as well as the interpretation of state law on which that decision rests.
Salve Regina Coll. v. Russell,
When interpreting state law, a federal court’s task is to determine how the state’s highest court would rule.
Konradi v. United States,
The Illinois Good Samaritan Act spans some 27 sections and applies in a variety of settings.
See, e.g.,
745 ILCS 49/65 (“choking victim at food-service establishment”); 745 ILCS 49/15 (emergency dental care). Our analysis centers on 745 ILCS 49/25. The provision provides, with omissions not relevant here: “Any ... [physician] who, in good faith, provides emergency care without fee to a person, shall not, as a result of his or her acts or omissions, except willful or wanton misconduct on the part of the person, in providing the care, be liable for civil damages.” The Act immunizes physicians from liability if they (1) provide emergency care, (2) without fee, and (3) do so in good faith.
Hernandez v. Alexian Bros. Health Sys.,
The parties’ primary dispute turns on what it means to provide emergency care without fee. Soleanicov argues that the Illinois Appellate Court answered the question in
Heanue
and that the interpretive linchpin is the word “fee.” The argument is that the relationship between UIC and the Crusader Clinic, combined with the fact that Soleanicov and Seidlin each drew a salary, means that they could not have charged a fee for their work within the meaning of the Good Samaritan Act. Employing a liberal use of brackets, Soleanicov says that the
Heanue
Court determined that a fee is “a very specific sort of relationship where the economic benefit is derived [by the physician providing emergency care] directly from the service performed.” Soleanicov Brief at 10 (brackets in original) (quoting
Heanue,
We read the
Heanue
Court to say something slightly different than what the defendants assert, and the ease’s discussion leaves us confident in that conclusion: a fee, as the term is used in the Good Samaritan Act, is simply a charge for medical services. In
Heanue,
a patient’s estate brought suit against a physician who furnished emergency care. The defendant physician was a partner of the medical group who provided treatment for Heanue, but was not the treating physician. After Heanue underwent an elective medical procedure, her post-operative medication was not working adequately. A nurse
*627
tried unsuccessfully to locate the treating physician and then paged the defendant physician’s medical practice. The defendant physician stepped in to provide treatment.
In concluding that the defendant physician had not charged a fee for his services,
Heanue
relies on and quotes the Black’s Law Dictionary definition. (Along with one other dictionary. There is no real difference between the two). Here is the definition of the word fee, which mirrors its ordinary meaning: “A charge for labor or services, esp. professional services.” Black’s Law Dictionary 629 (7th ed.1999) (def. 1). After providing the definition, the court then made the statement that Soleanicov excerpts in her brief: “These definitions do not encompass all relationships where some financial benefit flows to an individual; rather, they envision a very specific sort of relationship where the economic benefit is derived directly from the service performed. In other words, a fee is generated by and tied to the service performed.”
Heanue,
That charge-for-services understanding of the word fee is the best read of
Heanue
for several reasons. First, immediately after speaking of “fee” in terms of “relationships,” the
Heanue
Court said this: “In other words, a fee is generated by and tied to the service performed.”
Put simply, a fee ties labor to services. The identity of the entity responsible for paying for the services after they have been rendered, like the identity of the entity who has a right to collect on the bill, does not tell us whether there has been a “charge for labor or services.” Black’s,
supra,
at 629. After all, individuals often contract with insurance companies to reimburse their health care providers. The contract between the insurer and the insured will determine whether the insured must contribute a co-payment. In this case, actual payment was made on the bill from Medicaid, but for others private insurers will provide direct payment to a hospital, medical group, or solo practitioner.
See also Villamil v. Benages,
Multiple eases from the Illinois Appellate Court, though not addressing the question we face here, have framed the inquiry in terms of whether a doctor charged a fee for his or her services, evincing agnosticism on the question of how the physician was ultimately compensated.
E.g., Hernandez,
That addresses the issues related to Soleanicov. The analysis works slightly differently for Seidlin. According to Seidlin, he was in the hospital in street clothes and “just happened to be in the hallway” when Dr. Baxter asked for advice about Rodas. After finding Soleanicov, he provided assistance because there was no time to procure the help of a surgical assistant. Unlike, Soleanicov, he never submitted a billing form for the work he performed. “These facts alone establish beyond question that Dr. Seidlin is entitled to the protection afforded under the Good Samaritan Act.” Seidlin Brief at 16. Incorrect. Seidlin’s conclusion would be sound only if Rodas had not marshaled evidence of her own at summary judgment. Rodas points out that Seidlin’s explanation for why he did not charge for his services was that his services in assisting the delivery were minimal. However, he did not recall ever waiving a fee on that basis in the past. The decision to deviate from his ordinary practice creates a genuine issue of material fact about whether his decision not to bill was made in good faith.
Hernandez,
In sum, there is sufficient record evidence to survive summary judgment that Soleanicov billed for the emergency services she provided Rodas and that Seidlin made a bad faith decision not to bill. Therefore, the grant of summary judgment was not appropriate.
C. Remand
One final matter merits brief attention, and that is the course of proceedings upon remand. Our conclusion that the doctrine of derivative jurisdiction creates a procedural defect in removal suggests that derivative jurisdiction should ordinarily be raised within 30 days, 28 U.S.C. § 1447(c), but by its terms that provision applies only to plaintiffs who seek to remand a case. Likewise,
Grubbs
and
Caterpillar
by their terms speak only to the question of whether a court of appeals has power to review the judgment in a case that lands in federal court despite a defect in the removal process.
See Grubbs,
The Fourth Circuit considered the problem in a case in which removal was improper but the district court did not pass on the legal merits of a controversy. In that case, the appeals court reversed a district court’s conclusion that a plaintiffs claim was time-barred. After reversing, the Fourth Circuit noted that no headway had been made on the merits and instructed the district court to remand the case to state court.
Marshall v. Manville Sales Corp.,
We conclude that “considerations of finality, efficiency, and economy,”
Caterpillar,
III. Conclusion
For the reasons set forth above, we Reverse the judgment of the district court and Remand for further proceedings.
Notes
. The provision provides: "The court to which a civil action is removed under this section is not precluded from hearing and determining any claim in such civil action because the State court from which such civil action is removed did not have jurisdiction over that claim.”
. The conclusion that the court would have had original jurisdiction is easily reached. Claims against the United States under the Federal Tort Claims Act must be raised in federal court. 28 U.S.C. § 1346(b). Supplemental jurisdiction over the pendent party claims against Soleanicov and Seidlin would have been authorized by 28 U.S.C. § 1367(a).
. In Caterpillar, too, the citizenship of the parties was determined at the time of filing. Although the parties were incompletely diverse at the time of removal, the party who *622 created the defect in diversity dropped out of the case by the time of judgment. The feature is important, as it allows Caterpillar and Grupo Dataflux to be harmonized.
. Rodas and the United States urge that receiving compensation for medical services is by itself sufficient to fall outside of the Good Samaritan Act's protections.
Henslee v. Provena Hosps.,
