OPINION
The doctrine of derivative jurisdiction requires that a federal court’s jurisdiction over a removed case mirror the jurisdiction that the state court had over the action prior to removal. In this appeal, the district court applied the doctrine and dismissed a removed third-party claim against federal agency defendants because the state court did not possess jurisdiction over those defendants. Derivative jurisdiction has been frequently criticized and Congress has eliminated the doctrine for cases removed under 28 U.S.C. § 1441, the general removal statute. This abrogation, however, did not extend to cases removed under other provisions. Thus, our precedent, in accord with the statutory removal scheme, dictates the application of the derivative-jurisdiction doctrine in cases removed under the federal-officer removal statute, 28 U.S.C. § 1442. No authority exists for creating an exception to the doctrine that would apply in this case. Furthermore, application of derivative jurisdiction in this case does not violate the Equal Protection or Due Process Clauses of the Constitution. Accordingly, we affirm the district court’s dismissal of the third-party claim.
I.
The facts of this appeal are straightforward. City National Bank of West Virginia issued a series of three loans to John and Stacey Palmer. City National alleges that the loans were made in reliance upon the guarantee of the Farm Service Agency (“FSA”) of the U.S. Department of Agriculture (“USDA”). After City National issued the loans, the Palmers became delinquent with their payments, and the FSA did not make payment on the loans. City National then foreclosed on the Palmers’ farm. Thereafter, the Palmers brought suit in the Circuit Court of Kanawha County, West Virginia, against City National, alleging, inter alia, fraud and breach of contract. City National moved for leave to file a third-party complaint against the FSA and USDA (the “federal defendants”). The motion was granted, and City National served a third-party complaint upon the federal defendants, alleging that the FSA failed to honor the loan guarantees and seeking indemnity and contribution.
Pursuant to 28 U.S.C. § 1442(a)(1) (2000), the federal defendants filed a notice of removal, based on their status as federal agencies. After removal to the United States District Court for the Southern District of West Virginia, the federal defendants filed a motion to dismiss the third-party complaint pursuant to Federal Rule of Civil Procedure 12(b)(1) and to remand the remaining claims to state court. The federal defendants argued that in cases removed under § 1442(a)(1) the doctrine of derivative jurisdiction applied and the district court’s jurisdiction was identical to the state court’s jurisdiction prior to removal. Because the United States had not waived its sovereign immunity to contract and tort suits in state court, the state court lacked jurisdiction over the federal defendants. Thus, the federal defendants argued, the district court also lacked jurisdiction. Relying on the derivative-jurisdiction doctrine, the district granted the motion to dismiss, holding that the state court did not have jurisdiction over the third-party claim and thus the district court lacked jurisdiction over the claim as well. The district court remanded the remaining claims. This appeal followed.
*240 II.
Whether at the suggestion of the parties or otherwise, this Court has an obligation to verify the existence of appellate jurisdiction before considering the merits of an appeal.
See Hyman v. City of Gastonia,
In
Waco,
a third-party defendant removed a state case on the grounds of diversity.
After oral argument in this case, the Supreme Court issued its opinion in
Powerex,
551 U.S. -,
Powerex
concerned a suit by various plaintiffs in state court against certain energy companies, alleging that the companies conspired to fix prices in violation of California law.
See
The plaintiffs moved to remand the case to state court, arguing that Powerex was not a foreign state and that the cross-claims against the U.S. agencies and BC Hydro were barred by sovereign immunity. Id. The district court concluded that (1) the federal agencies were immune from suit in state court; (2) BC Hydro enjoyed sovereign immunity under the FSIA; and (3) Powerex did not qualify as a foreign state under the FSIA. Id. at 2414-15. The district court then remanded the entire case to state court. Id. at 2415. The federal agencies and Powerex appealed. The former argued that the district court should have dismissed them outright because of sovereign immunity. Powerex argued that it was a foreign state under the FSIA and thus entitled to remove. The plaintiffs argued that § 1447(d) barred both appeals. The Ninth Circuit rejected the invocation of § 1447(d), concluding that the provision did not bar it from reaching issues of law decided by the district court prior to remand. Id.
After concluding that § 1447(d) applies to remands for lack of subject-matter jurisdiction even where the removal itself was proper, and that the remand of the district court was based on a lack of subject-matter jurisdiction, the Supreme Court noted that the Ninth Circuit relied upon the Waco exception in rejecting the application of § 1447(d). Id. at 2419. The Court held that Waco “does not permit an appeal when there is no order separate from the unreviewable remand order.” Id. The Court continued, noting that Powerex “can point to no District Court order, separate from the remand, to which it objects and to which the issue of its foreign sovereign status is material.” Id. In conclusion, Powerex’s “invocation of Waco amounts to a request for one of two impermissible outcomes: an advisory opinion as to its FSIA status that will not affect any order of the District Court, or a reversal of the remand order;” Id. After concluding that no other exception to § 1447(d) existed, the Court vacated the relevant portion of the Ninth Circuit’s judgment and remanded with instructions to dismiss for want of jurisdiction. Id. at 2421.
Our most recent discussion of the
Waco
doctrine made clear that “the purportedly reviewable order [must] have a conclusive effect upon the parties’ substantive rights.”
In re Blackwater,
The requirements set forth in
In re Blackwater
governing the applicability of the
Waco
exception conform to
Powerex’s
recent pronouncement. Both requirements ensure that the appealed order is a truly separate order from the remand order and that any action taken by this Court on appeal does not affect the remand order. The conclusiveness requirement guarantees that any purportedly ap-pealable decision is a binding decision on the merits, and not a mere finding of the district court that may be relitigated in the state court upon remand.
See, e.g., id.
at
*242
590 (“[T]he district court’s finding that complete preemption did not create federal removal jurisdiction will have no preclusive effect on a subsequent state-court defense of federal preemption.”). Similarly, by requiring logical and factual severability, the disaggregation requirement mandates that any purportedly reviewable decision made by the district court was actually prior to the remand order and was a legally discrete conclusion. The severability requirement ensures that the appealable decision was truly distinct from the remand decision and not “merely a subsidiary legal step[ ] on the way to [the district court’s] determination that the case was not properly removed.”
Nutter v. Monongahela Power Co.,
The conclusion that the
In re Blackwa-ter
requirements satisfy
Powerex
is supported by Justice Scalia’s discussion of the
Waco
exception in his dissent in
Osborn v. Haley,
549 U.S. -,
In dissent, Justice Scalia did not view the Westfall Act as conflicting with § 1447(d) and analyzed whether the district court’s refusal to substitute the United States as a defendant fell within the Waco exception to § 1447(d). See id. at 908-09 (Scalia, J., dissenting). Justice Scalia concluded:
[T]here is a crucial distinction between [Waco ] and [Osborn ]: In Waco, reversal of the dismissal would not have subverted the remand. There was no question that the suit would proceed in state court regardless of whether the diverse party was rightfully or wrongfully dismissed. Nowhere did the Waco Court so much as hint that the District Court might need to reexamine its remand order; to the contrary, it was clear that the remand would occur, no matter what.... In other words, the remand order and the dismissal order were truly “separate orders”; we could review— even reverse — -the dismissal order without affecting the remand or its impact on the case.
Id.
(citation omitted) (quoting
Waco,
The conclusiveness and disaggregation requirements of In re Blackwater accord *243 with Justice Scalia’s persuasive discussion of when a purportedly reviewable order is truly separate from a remand order. A district court decision that has a preclusive effect on the parties and that is logically and factually separable from the remand order is a decision that can be reviewed by this Court without affecting the remand order. Reversal of an independently binding decision, separated from the remand order logically and factually, would not undermine the remand order itself. In sum, the In re Blackwater requirements are sufficient to ensure that this Court reviews only decisions that are separate orders from unreviewable remand orders in keeping with the holding of Powerex.
Thus, in order to determine whether we have appellate jurisdiction over City National’s appeal, we must decide whether the district court’s application of derivative jurisdiction and its subsequent dismissal of the United States meet the
In re Blackwater
requirements. The first requirement is that “the purportedly reviewable order have a conclusive effect upon the parties’ substantive rights.”
In re Blackwater,
In addition to conclusiveness,
In re Blackwater
requires that a purportedly reviewable decision be logically and factually severable from the remand order.
Were we to reverse the dismissal of the federal defendants, the remand order would not be “subverted.” The remand order did not include the federal defen
*244
dants, and the state-court proceedings between the Palmers (as plaintiffs) and City-National (as defendant) will proceed regardless of any action we take on this appeal. Thus, as in
Waco,
the suit will proceed in state court regardless of whether the federal defendants were correctly dismissed.
See Osborn,
127 S.Ct. at
909
(Scalia, J., dissenting). By contrast, in
Powerex,
Powerex was a party to the remand order. If the district court’s decision on Powerex’s foreign sovereign status were reversed, any appellate court action regarding Powerex would, by necessity, affect the remand order. If the appellate court chose to reverse the district court, but could take no action, then its decision on Powerex’s foreign sovereign status would have been “an advisory opinion as to [Powerex’s] FSIA status.”
Powerex,
Thus, the requirements of In re Black-water are satisfied: City National appeals from a ruling of the district court that is conclusive as well as logically and factually severable from the remand order. Because the issue of the district court’s application of derivative jurisdiction is a reviewable order wholly separate from its remand order, we have appellate jurisdiction to consider City National’s appeal under the Waco exception to § 1447(d).
III.
We review de novo a dismissal for lack of subject-matter jurisdiction.
Welch v. United States,
A.
The derivative-jurisdiction doctrine arises from the theory that a federal court’s jurisdiction over a removed case derives from the jurisdiction of the state court from which the case originated. As the Supreme Court explained in
Lambert Run Coal Co. v. Baltimore & Ohio Railroad Co.,
*245
Accordingly, in 1985, Congress amended the general removal statute, 28 U.S.C. § 1441, by adding § 1441(e): “The court to which such civil action is removed 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.” Judicial Improvements Act of 1985, Pub.L. No. 99-336, § 3, 100 Stat. 633, 637 (1986) (codified as amended at 28 U.S.C.A. § 1441(f) (2007)). Following the 1985 amendment, this Court continued to apply the doctrine for removals effectuated under sections other than § 1441, including § 1442.
See Kasi v. Angelone,
B.
Whether the Eighth Circuit correctly interpreted the 1986 amendment is academic, because in 2002 Congress again amended § 1441, creating a new § 1441(e) and redesignating the prior § 1441(e) as § 1441(f) and slightly changing its language. 21st Century Department of Justice Appropriations Authorization Act, Pub.L. No. 107-273, § 11,020(b)(3)(A), 116 Stat. 1758,1827 (2002). Thus, the new § 1441(f) reads: “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.” Id. (emphasis added).
Commentators speculate that the amendment was intended to endorse the
Fredericks
approach and be the death knell of derivative jurisdiction for all removals.
See, e.g.,
14B Charles Alan Wright, Arthur R. Miller, & Edward H. Cooper,
Federal Practice & Procedure: Jurisdiction Sd
§ 3721, at 191 (2007 Supp.). Yet these same commentators conclude that the amendment did not accomplish this purpose: “[N]ew § 1441(f) limits the abrogation of the derivative jurisdiction doctrine to cases removed under 28 U.S.C.A. § 1441.”
Id.
The legislative history of the 200.2 amendment is “sparse,”
Glorvigen v. Cirrus Design Corp.,
No. 06-2661,
Following the 1985 amendment to § 1441, this Court has applied the derivative-jurisdiction doctrine in several cases involving removal under § 1442. Whatever the intent of the 2002 amendment, its result was that § 1441(f) is more clear than former § 1441(e) in abrogating derivative jurisdiction only with respect to removals effectuated under § 1441. Thus, our holdings in Kasi, Williams, and Cromer are strengthened, rather than weakened, by the enactment of the new § 1441(f). Accordingly, because the plain language of § 1441(f) limits the abrogation of derivative jurisdiction to removals under § 1441 and because our precedent holds that the doctrine is viable for removals under § 1442, the doctrine applies to the removal at issue in this case.
C.
City National urges that we create and apply an exception to the derivative-jurisdiction doctrine because West Virginia law compelled City National to implead the federal defendants or waive its claims against them. There is no authority in this Circuit or any other that would allow us to craft specific exceptions to the derivative-jurisdiction doctrine based on state rules of procedure. Because the application of the derivative jurisdiction doctrine affects a district court’s jurisdiction over the case, case-specific exceptions are not appropriate. In this case, the state court did not possess jurisdiction over City’s third-party claim against the federal defendants. Accordingly, the district court did not gain proper jurisdiction of the claim upon its removal.
Fredericks
is not to the contrary. Rather than creating an exception, the Eighth Circuit abrogated the entire doctrine on the basis of its view of the equity of the statute.
See Fredericks,
IV.
City National raises two constitutional arguments that the application of the derivative jurisdiction in this case violates both the Equal Protection and Due Process Clauses. Both of these arguments fail.
A.
In considering an equal protection challenge, “a statutory classification that neither employs inherently suspect distinctions nor burdens the exercise of a fundamental constitutional right will be upheld if the classification is rationally related to a legitimate state interest.”
Star Scientific Inc. v. Beales,
In this case, City National claims that application of derivative jurisdiction in a case removed under § 1442, when the doctrine would not be applied in a case removed under § 1441, unconstitutionally burdens its fundamental right of access to the courts. The district court’s application
*247
of derivative jurisdiction prevented City National from litigating its claims against the federal defendants in the removed action. City National remains free to bring a separate action against the federal defendants in an appropriate forum,
i.e.,
the Court of Federal Claims, for its contract action, in accordance with the Tucker Act, and a district court, for its indemnity claims, in accordance with the FTCA. Thus, any fundamental right of judicial access that City National has to bring its claims has not been infringed upon as City National has not yet availed itself of the appropriate federal fora for resolving its claims against the federal defendants.
Cf. Lewis v. Casey,
City National argues that if it brought a subsequent suit for indemnity or contribution against the federal defendants in a proper forum, any court would apply West Virginia compulsory joinder law to bar the action. Even assuming,
arguendo,
that this hypothesis is correct, the operation of a substantive rule of law to bar a suit does not violate the right of access to a judicial forum.
See Plyler,
Thus, the application of the derivative-jurisdiction doctrine in this case does not burden City National’s fundamental right to access the courts. As such, our review proceeds under the rational-basis standard.
See, e.g., Plyler,
Removal under § 1441 and removal under § 1442 serve two different ends: “Section 1441 relates to the rights of individuals. Section 1442, although dealing with individuals, vindicates also the interests of government itself; upon the principle that it embodies ‘may depend the possibility of the general government’s preserving its own existence.’ ”
Bradford v. Harding,
The distinctions between general removal and federal-officer removal provide plausible reasons for the congressional action at issue in this case. For example, because any case removed under § 1441 could have originally been brought in federal court, Congress may have thought it irrelevant whether the state court had jurisdiction over the action prior to removal. On the other hand, a case removed under § 1442 may not have had original federal jurisdiction, and thus Congress decided to retain the traditional rule that removal jurisdiction is derivative of state court jurisdiction prior to removal. In addition, Congress may have viewed federal-officer removal as guaranteeing a federal prerogative — adjudication of federal defenses in a federal forum — in as narrow a manner as possible, allowing a federal officer to remove, but mandating that the jurisdiction of the federal court over the removed action derive solely from the state court’s jurisdiction. Although the derivative-jurisdiction doctrine may be arcane or inefficient, our inquiry is one of mere rationality. Accordingly, we reject City National’s equal protection argument as there is a conceivable rational basis for Congress abrogating derivative jurisdiction for removals effectuated via § 1441, but retaining the doctrine for cases removed under § 1442.
B.
Finally, City National argues that depriving it of the right to sue the federal defendants amounts to a deprivation of its property interests without due process of law.
To prove a due process claim, a litigant must show that it was deprived of a protected interest without due process of law.
See, e.g., Elmco Props., Inc. v. Second Nat’l Fed. Sav. Ass’n,
V.
For the foregoing reasons, we conclude that we possess jurisdiction over City Na *249 tional’s appeal, but deny that appeal because the district court properly applied the doctrine of derivative jurisdiction in concluding that it did not possess subject-matter jurisdiction over City National’s third-party claims against the federal defendants. Accordingly, we affirm the ruling of the district court.
