Before: LIVINGSTON and LYNCH, Circuit Judges, and STANCEU, Judge.[*]
GERARD E. LYNCH, Circuit Judge:
This appeal requires us to decide when a provision of the Class Action Fairness Act of 2005 ("CAFA") bars appellate review of orders remanding securities class actions to state court.
Plaintiffs-appellees commenced this putative class action in New York State Supreme Court. The case was removed to the United States District Court for the Southern District of New York (Richard J. Holwell, J.). Plaintiffs-appellees moved to remand the case to state court for lack of subject matter jurisdiction. They argued that, while CAFA extended federal jurisdiction for most class actions meeting certain monetary and diversity requirements, it did not apply to this action because the statute exempted suits involving claims that "relate[d] to the rights, duties[,] ... and obligations relating to or created by or pursuant to any security." 28 U.S.C. § 1332(d)(9)(C). Additionally, plaintiffs-appellees argued that no other basis for federal jurisdiction existed. The district court granted plaintiffs-appellees' motion to remand, and defendants-appellants appealed to this Court.
We construe the language of another provision of CAFA, 28 U.S.C. § 1453, which governs removal of class actions and appellate review of orders remanding such actions to state court. Like the parallel exception in the provision creating federal jurisdiction over class actions, § 1453(d)(3) exempts from appellate review orders remanding any class action that solely involves "a claim that relates to the rights, duties[,] ... and obligations relating to or created by or pursuant to any security...." We conclude that the present action falls within this provision. Accordingly, we do not have jurisdiction to hear this appeal and must dismiss it.

BACKGROUND
Defendants are affiliated corporations in the mortgage business. Defendant Countrywide Financial Corporation is a holding company, of which the other defendants are subsidiaries. One subsidiary, defendant Countrywide Home Loans, Inc., originates loans to individual consumers. The other subsidiary, defendant Countrywide *25 Home Loans Servicing, LP, now known as BAC Home Loans Servicing, LP, ("Countrywide Servicing"), services the loans originated by Countrywide Home Loans.
To raise money to lend to consumers, Countrywide Home Loans entered into a number of securitization transactions. In these transactions, Countrywide Home Loans sold its mortgages to specially created trusts, which received payment of interest and principal from mortgage borrowers. The trusts in turn sold certificates to investors. These securities entitled their owners to repayments of their principal, as well as interest payments. Because the trusts themselves lacked the capacity to administer the loans, they entered into agreements with Countrywide Servicing to administer the mortgages on their behalf. The terms of these securitization transactions, as well as the rights and duties of the parties to them, were laid out in contracts known as "pooling and servicing agreements" ("PSAs"). Countrywide Home Loans and Countrywide Servicing, as well as the trusts' trustee, The Bank of New York, and various other entities, were parties to the PSAs, but the certificate holders and Countrywide Financial were not.
In the summer of 2008, the attorneys general of seven states filed lawsuits accusing the Countrywide businesses ("Countrywide") of violating laws against predatory lending. The states alleged that Countrywide engaged in deceptive sales practices, charged unlawful fees, and made loans it had no reasonable basis to think could be repaid. Countrywide later agreed to a multistate settlement, according to which it was required to modify the terms of many of the mortgages owned by the trusts and administered by Countrywide Servicing on behalf of the trusts. Modifying the loans created the possibility that the homeowners would make smaller payments of interest and principal to the trusts, thereby decreasing the value of the certificates.
Plaintiffs are holders of certificates issued by the trusts. They filed this putative class action in New York State Supreme Court, seeking declaratory judgments that Countrywide Servicing is required under the terms of the PSAs to repurchase the modified loans from the trusts at a price equal to their unpaid principal plus any accrued interest. They cite language in the PSAs to the effect that "[Countrywide Servicing] may agree to a modification of any Mortgage Loan ... if ... [it] purchases the Modified Mortgage Loan from the Trust Fund...."
Defendants promptly removed the action to the Southern District of New York. In their notice of removal, defendants cited two independent bases for federal jurisdiction. First, defendants claimed original diversity jurisdiction under CAFA, 28 U.S.C. § 1332(d)(2), which generally allows district courts to exercise jurisdiction over class actions based solely on state law provided that minimal diversity is present and the amount in controversy exceeds $5,000,000. Second, defendants asserted federal question jurisdiction under 28 U.S.C. § 1331, arguing that plaintiffs' state-law claim required the court to resolve a disputed, substantial question of federal law. Specifically, defendants claimed that Countrywide Servicing's duties under the PSAs were defined by the Housing and Economic Recovery Act of 2008 ("HERA"), which at 15 U.S.C. § 1639a provides a safe harbor for servicers of pooled mortgages who modify home loans meeting certain conditions. They argued that since the court would be required to adjudicate the applicability of this safe harbor in order to determine the merits of plaintiffs' claim, federal jurisdiction *26 was proper under Grable & Sons Metal Products v. Darue Engineering & Manufacturing, 545 U.S. 308, 315, 125 S.Ct. 2363, 162 L.Ed.2d 257 (2005).
Two weeks later, plaintiffs moved to remand. Plaintiffs did not dispute that their action met the diversity and amount-in-controversy requirements for CAFA jurisdiction. They argued, however, that their suit fell within an exception to CAFA jurisdiction for actions "that relate[ ] to the rights, duties (including fiduciary duties), and obligations relating to or created by or pursuant to any security. ..." 28 U.S.C. § 1332(d)(9)(C). They further argued that federal question jurisdiction was extended by Grable only to those state-law claims of which federal law was an essential element. Federal law, they asserted, was not an element of their claim. Rather, the safe harbor of HERA, if it applied, would simply provide a federal defense to a claim under state law, and therefore was not a basis for subject matter jurisdiction. The district court agreed with both of plaintiffs' arguments and remanded.
Defendants petitioned to file the present appeal pursuant to 28 U.S.C. § 1453(c), which authorizes the courts of appeals to hear at their discretion appeals from orders granting or denying motions to remand class actions. We granted petitioners leave to file this appeal, which we considered on an expedited basis in accordance with the time limit set out in 28 U.S.C. § 1453(c)(2).[1]

DISCUSSION
This case requires us to interpret certain provisions of CAFA, which expanded the jurisdiction of the federal courts to allow class actions originally filed in state courts that conform to particular requirements to be removed to federal district courts. 28 U.S.C. §§ 1332(d), 1453(b); Estate of Pew v. Cardarelli, 527 F.3d 25, 30 (2d Cir.2008). Class actions removed under CAFA may be remanded to originating state courts pursuant to the general remand statute, 28 U.S.C. § 1447. See 28 U.S.C. § 1453(c)(1) ("Section 1447 shall apply to any removal of a case under this section. ..."). The party opposing remand generally bears the burden of showing that federal jurisdiction is proper. Blockbuster, Inc. v. Galeno, 472 F.3d 53, 57-58 (2d Cir.2006). However, once the general requirements of CAFA jurisdiction are established, plaintiffs have the burden of demonstrating that remand is warranted on the basis of one of the enumerated exceptions. See Brook v. UnitedHealth Group Inc., No. 06 Civ. 12954(GBD), 2007 WL 2827808, at *3 (S.D.N.Y. Sept.27, 2007); accord Serrano v. 180 Connect, Inc., 478 F.3d 1018, 1021-22 (9th Cir.2007); Hart v. FedEx Ground Package Sys., Inc., 457 F.3d 675, 679-80 (7th Cir.2006); Frazier v. Pioneer Ams. LLC, 455 F.3d 542, 546 (5th Cir.2006).

I
As a general rule, an order to remand is not appealable. See 28 U.S.C. § 1447(d). At the same time that CAFA expanded the jurisdiction of federal courts over most class actions, however, it expanded *27 the jurisdiction of the courts of appeals to hear appeals of orders remanding class actions to state courts. 28 U.S.C. 1453(c); see Coll. of Dental Surgeons of P.R. v. Conn. Gen. Life Ins. Co., 585 F.3d 33, 37-38 (1st Cir.2009). But 28 U.S.C. § 1453(d) sets forth three circumstances under which appellate review of such orders is barred, only one of which is relevant to the case at bar:[2]
(d) Exception.  This section shall not apply to any class action that solely involves
. . .
(3) a claim that relates to the rights, duties (including fiduciary duties), and obligations relating to or created by or pursuant to any security (as defined under section 2(a)(1) of the Securities Act of 1933 (15 U.S.C. 77b(a)(1)) and the regulations issued thereunder).
This exception to appellate jurisdiction over remand orders of class actions is identical to the third of three exceptions to CAFA's grant of original federal diversity jurisdiction at 28 U.S.C. § 1332(d)(9)(C).[3] We must therefore construe the provisions together. If we find that the exception of § 1332(d)(9)(C) does not apply to this action and that the district court had jurisdiction over it under CAFA, we will necessarily find that we have jurisdiction to reverse a remand order premised on the district court's erroneous conclusion. See Cardarelli, 527 F.3d at 31. On the other hand, if the district court lacked CAFA jurisdiction over the class action because it falls within the exception, we similarly lack jurisdiction to review the order remanding the action and must dismiss the appeal. See id. As always, we have jurisdiction to determine our jurisdiction. Brodsky v. U.S. Nuclear Regulatory Comm'n, 578 F.3d 175, 182 (2d Cir.2009).
What this means for the case at bar is that we may examine only one of the two claims defendants make to federal jurisdiction. Defendants argue both that the district court had jurisdiction under CAFA and also that it had an independent basis for federal question jurisdiction under 28 U.S.C. § 1331. If they had raised only § 1331 as a basis for jurisdiction to the district court, and if the district court had remanded solely upon a finding that such jurisdiction did not exist, our review would be barred by 28 U.S.C. § 1447(d). It is only if the expansion of appellate jurisdiction under CAFA provided by § 1453 applies that we may review the district *28 court's order. If § 1453 applies, however, the district court necessarily also had jurisdiction over the class action, since none of CAFA's other jurisdictional exceptions are applicable. On the other hand, if we find that the case at bar fits within the exception of § 1453(d)(3), we lack jurisdiction to review defendants' arguments that the district court's order of remand was improper on other grounds.[4]

II
We examined the scope of the §§ 1332(d)(9)(C) and 1453(d)(3) exceptions to CAFA jurisdiction in Estate of Pew v. Cardarelli, 527 F.3d 25 (2d Cir.2008). In that case, the plaintiffs were purchasers of unsecured debt instruments issued by Agway, Inc., an agricultural supply and marketing cooperative. After Agway declared bankruptcy, plaintiffs filed suit against Agway's officers and its auditor in New York Supreme Court, alleging that Agway's financial statements had fraudulently concealed Agway's insolvency. Plaintiffs sought relief solely under the New York state consumer fraud statute. Defendants removed the suit to federal court under CAFA, and plaintiffs moved to remand. The district court determined that CAFA jurisdiction was absent, because the suit involved a claim "relate[d] to the rights, duties (including fiduciary duties), and obligations relating to or created by or pursuant to [a] security." § 1332(d)(9)(C).
We reversed. Our analysis began by noting that despite broad language that would seem to exempt any claim that "relates to ... any security," the exception could not have been intended to cover all securities claims, no matter their nature. Such an understanding of the provision would render superfluous the phrase "rights, duties (including fiduciary duties), and obligations relating to or created by or pursuant to," which plainly was intended to limit the scope of the exception. Additionally, it would render superfluous § 1332(d)(9)(A), which exempted from CAFA jurisdiction any class action that solely involves a claim concerning a security covered under the Securities Act of 1933. Interpreting § 1332(d)(9)(C) therefore required us to decide what limiting principle to apply to the broad language of the provision.
To answer this question, we focused on the fact that the exception only applied to suits seeking to enforce "rights, duties, [and] obligations relating to or created by or pursuant to" securities. We determined that this language was intended to differentiate claims based either on the "terms of the instruments that create and define securities ... [or on the] duties imposed on persons who administer securities," *29 Cardarelli, 527 F.3d at 33, from claims based on rights arising from independent sources of state law. The key distinction between suits that were immune from removal under CAFA and those that were not is that immune suits sought to enforce the rights of the securities "holders as holders." Id. at 32. In Cardarelli, however, plaintiffs' claim sought to enforce their rights not as holders, but as purchasers; they asserted that the transaction in which they had acquired the notes was tainted by fraud. Thus, the claims did not seek to enforce rights, duties or obligations that were pursuant to or created by the securities, but rather rights granted to consumers by a New York statute. Plaintiffs' suit was therefore removable under CAFA.
In contrast to Cardarelli, plaintiffs here seek enforcement of their rights as holders rather than as purchasers of securities. Plaintiffs sue under a provision of the PSAs that they claim requires Countrywide Servicing to repurchase from the trust those loans which Countrywide agreed to modify. Plaintiffs' asserted right to force Countrywide Servicing to repurchase the loans arises from the deal instruments themselves, not from an extrinsic provision of state law, such as the consumer fraud statute that formed the basis of the action in Cardarelli. Thus, plaintiffs' claim "relates to the rights, duties ... and obligations relating to or created by or pursuant to" their certificates, and their suit is not removable under CAFA.
It is true that plaintiffs sue not to enforce a term of the certificates themselves, but rather to enforce a term of the PSAs. But simply because the provision on which the suit depends does not appear on the certificates, it doesn't follow that the claim is not pursuant to or created by the security. The principle we stated in Cardarelli is that the securities exception of §§ 1332(d)(9)(C) and 1453(d)(3) applies to suits that enforce "the terms of instruments that create and define securities," 527 F.3d at 33, and that it does not apply to suits to enforce rights that are "superimposed by a state's corporation law or common law," id. at 31. The fact that a certificate holder's rights may be enumerated in an instrument other than the security itself is not material. Securities are created and defined not simply by their own text, but also by any number of deal instruments executed between various parties. Indeed, we made clear in Cardarelli that the "instruments that create and define securities" include documents such as certificates of incorporation and bond indentures. Id. For this reason, the fact that plaintiffs seek enforcement of a term of the PSAs  trust agreements similar to bond indentures in many respects  rather than of the certificates does not affect our conclusion that this suit is not removable under CAFA.
Likewise, the fact that the certificate holders are not themselves parties to the PSAs is not relevant. The focus of the inquiry is on the source of the right that the plaintiff's claim seeks to enforce. As long as a plaintiff's claim seeks enforcement of a right that arises from an appropriate instrument, it falls within the exception of §§ 1332(d)(9)(C) and 1453(d)(3), regardless of whether the plaintiff is a party to the instrument.

III
Defendants argue that under our decision in Cardarelli, the jurisdictional exceptions of §§ 1332(d)(9)(C) and 1453(d)(3) do not apply to plaintiffs' claim. Cardarelli, they assert, stands for the proposition that these exceptions to CAFA jurisdiction apply only to disputes over the terms of securities. Such terms may be defined in *30 other documents, such as bond indentures, but suits depending on non-definitional provisions of such documents are not immune from CAFA jurisdiction. Defendants argue that while the PSAs may create and define the terms of the certificates, the PSAs' repurchase provision does not itself define the certificates. Accordingly, they argue, plaintiffs' suit is subject to removal.
In making this argument, defendants attempt to draw on the legislative history of CAFA. They argue that this history demonstrates that Congress intended to limit CAFA's jurisdictional exceptions to suits for which federal jurisdiction already existed under federal securities law and to disputes concerning corporate governance, an area in which the Delaware state courts had special expertise. They submit that the exceptions of §§ 1332(d)(9)(C) and 1453(d)(3) were meant to preserve the ability of plaintiffs to bring suit in Delaware against the managers of the companies in which they invested over the definition of the terms of their investments and urge that § 1332(d)(9) be "narrowly construed" to cover only "disputes over the meaning of terms of a security" that relate to corporate governance and not to extend to suits over non-definitional provisions of documents other than the securities themselves.
This argument must be rejected. First, defendants misconstrue the rule we announced in Cardarelli, which examines the source of the right that the suit seeks to enforce. In that case, we held that §§ 1332(d)(9)(C) and 1453(d)(3) applied to "suits that seek to enforce the terms of instruments that create and define securities." 527 F.3d at 33 (emphasis added). We did not read the exceptions to apply only to suits that enforced terms that create and define securities, nor did we instruct the district courts to determine whether the claims pressed by plaintiffs turned on document provisions that were adequately "definitional" of the securities in question.
Even if we were to examine the extent of these jurisdictional exceptions anew, we would arrive at the same conclusion. First, the legislative history cited by defendants is largely inapplicable. Most of the statements cited by defendants were made during a congressional hearing on an earlier version of the bill, more than 5 years before CAFA was enacted. At the time of this hearing, the language that became § 1332(d)(9)(C) formed part of a provision that was titled the "Corporate Governance Exception." However, when CAFA was eventually enacted more than half a decade later, § 1332(d)(9)(C) had become its own freestanding jurisdictional provision, distinct from the now-separate Corporate Governance Exception.[5] The legislative history does not compel us to limit the provision to issues of corporate governance.
Furthermore, we must interpret the statute to create a jurisdictional exception that the district courts can actually apply. Whether a particular provision of a document does or does not define a security is too amorphous a criterion to serve as a basis for determining jurisdiction. Adopting such a standard would greatly complicate the work of district judges faced with suits for which jurisdiction is asserted under CAFA. The difficulties of defendants' proposed approach are demonstrated by the very provision of the PSA at issue in plaintiffs' suit: the buyback provision of the PSAs. While this provision does not define a term of plaintiffs' certificates as clearly as would, for instance, a provision calculating the rate of interest to be paid *31 on the certificates, it directly affects the amount of money available to certificate holders in a particular circumstance, the mortgage servicer's modification of the mortgages in the trust. As such, it arguably "defines" the obligation of the trustee to make monthly distributions from the trust corpus, a duty stated on the reverse of the certificates. Whether a term such as the buyback provision at issue here does or does not "define" the securities to which it relates is too nebulous an inquiry for the preliminary stages of litigation.
Accordingly, even were we empowered to do so, we would not depart from our holding in Cardarelli that §§ 1332(d)(9)(C) and 1453(d)(3) apply to "suits that seek to enforce the terms of instruments" that create or define securities, no matter which provisions of such instruments plaintiffs' suit seeks to enforce.

IV
Defendants also argue that even if plaintiffs' suit "relates to the rights, duties ... and obligations relating to or created by or pursuant to" their certificates, it does not relate "solely" to such rights, duties, and obligations and therefore does not fall under the §§ 1332(d)(9) and 1453(d) exceptions. They argue that two aspects of plaintiffs' claim in particular raise collateral legal issues that go beyond the interpretation of the certificates: first, they assert that the naming of Countrywide Financial as a defendant, even though Countrywide Financial is not a party to the PSAs, means that plaintiff's claim "involves" state alter ego law; and second, they argue that in order to succeed in their claim plaintiffs must show that Countrywide Servicing's actions were not authorized under § 3.01 of the PSAs, which supposedly provides Countrywide with a defense as long as it as acting within the "customary and usual standards of practice." Therefore, defendants argue, in order to succeed in their claim, plaintiffs must show that Countrywide's modification actions are not "standard industry practice," as defined in federal law at 15 U.S.C. § 1639a(c). On both these bases, defendants contend that plaintiffs' claim does not "solely involve ... a security" and therefore should be amenable to CAFA jurisdiction.
Defendants' argument hinges on a strained reading of the words "[t]his section shall not apply to any class action that solely involves...." Needless to say, the phrase "solely involves" cannot be stretched so far as to limit the exception in §§ 1332(d)(9) and 1453(d) to class actions that raise no collateral issues and for which there are no affirmative defenses. Defendants' interpretation of the prefatory phrase "solely involves" as strictly limiting CAFA's jurisdictional exceptions is especially unpersuasive in the light of the expansive language of the exceptions themselves. Sections 1332(d)(9)(A) and 1453(d)(1) exempt from CAFA jurisdiction any claim "concerning a covered security," (emphasis added), while § 1332(d)(9)(B) and (C), as well as § 1453(d)(2) and (3), use the equally broad phrase "relates to." If Congress had intended these provisions to apply only to class actions that involve no legal issues extraneous to the primary claim, they would have used language that was more clearly limiting.
Furthermore, we must reject an interpretation of the statutory text that would render the jurisdictional exception of §§ 1332(d)(9)(C) and 1453(d)(3) nugatory. Almost any securities claim under state law will necessarily "involve" defenses  such as statutes of limitations  and collateral issues  such as state contract law. Nothing differentiates New York alter ego law or Countrywide's putative defense under HERA from the sorts of affirmative defenses and collateral issues that arise in *32 virtually every lawsuit. Construing the phrase "solely involves" to disqualify such suits from the jurisdictional exceptions would mean that practically every state securities class action would be amenable to CAFA jurisdiction. Congress cannot have intended its exceptions to CAFA jurisdiction to be essentially meaningless.
Defendants' interpretation is particularly unpersuasive given that an alternative reading, more consistent with the purposes of CAFA, is readily apparent. Interpreted in light of those purposes, the phrase "solely involves" ensures that federal jurisdiction under CAFA cannot be defeated by adding a claim that falls within a § 1332(d)(9) exception to a class action complaint advancing one or more other claims. Accordingly, we conclude that plaintiffs' class action in this case, which presents only a single claim grounded in the terms of a document that creates and defines a security, "solely involves" a claim falling with the exception provided in §§ 1332(d)(9)(C) and 1453(d)(3).

V
Lastly, we must address defendants' contention that the remand of plaintiffs' action to state court would defeat the legislative purpose of CAFA, which is to provide federal jurisdiction to class actions "of national importance." CAFA, Pub.L. No. 109-2, § 2(b)(2), 119 Stat. 4, 5 (2005). While we are cognizant that Congress dramatically expanded federal jurisdiction over class actions through CAFA, this generalized legislative purpose cannot override the clear meaning of §§ 1332(d)(9) and 1453(d), which plainly allow some large class actions to remain in state court. If Congress meant the consideration of a class action's importance to the nation as a whole to trump these limiting provisions, it would have indicated that intent. Congress wisely chose not to leave it to the federal courts to assert jurisdiction over whatever class actions seemed to judges to be "of national importance"  a standard much too amorphous to admit of consistent judicial application  but instead to define concrete criteria for federal jurisdiction under CAFA, and to use specific language to define exceptions to that jurisdiction. We are governed by that language and not by defendants' self-serving assertion of the "national importance" of this litigation.
We conclude, therefore, that plaintiffs' sole claim "relates to the rights, duties ... and obligations relating to or created by or pursuant to [a] security." The case therefore falls within the exception to appellate jurisdiction defined by 28 U.S.C. § 1453(d)(3). Because we lack jurisdiction to hear this appeal, we must dismiss it.

CONCLUSION
Accordingly, for the foregoing reasons, the appeal is DISMISSED for lack of appellate jurisdiction.
NOTES
[*]  The Honorable Timothy C. Stanceu, Judge, United States Court of International Trade, sitting by designation.
[1]  28 U.S.C. § 1453(c)(2) requires that a court considering such an appeal "complete all action... not later than 60 days after the date on which such appeal was filed...." Defendants-appellees' motion for leave to appeal was granted on December 17, 2009. Oral argument in this case was heard nearly 60 days later, on February 11, 2010. Section 1453(c)(3), however, allows the court of appeals to grant either a 10-day extension of time period for "good cause shown and in the interests of justice" or an indefinite extension at the agreement of the parties. At argument, the parties agreed to a 90-day extension of the deadline for the Court to render a decision on the appeal.
[2]  28 U.S.C. 1453(d) provides two other exceptions to appellate review of remand orders, both of which mirror the exceptions to CAFA diversity jurisdiction under § 1332(d)(9). The first exempts suits "concerning a covered security as defined under 16(f)(3) of the Securities Act of 1933," § 1332(d)(9)(A) and § 1453(d)(1), and the second exempts suits that "relate[] to the internal affairs or governance of a corporation or other form of business enterprise and that arise[] under or by virtue of the laws of the State in which such corporation or business enterprise is incorporated or organized," § 1332(d)(9)(B) and § 1453(d)(2). Subsection (A) relates to claims concerning securities covered under the Securities Act, for which jurisdiction exists elsewhere under federal securities law, while Subsection (B) applies to suits on issues of corporate governance. See Cardarelli, 527 F.3d at 30. In this case, there is no dispute that the certificates are not covered securities under federal law and that the claim does not concern issues of corporate governance.
[3]  CAFA also provides numerous other jurisdictional exceptions, some of which apply only at the discretion of the district court. See, e.g., 28 U.S.C. § 1332(d)(3) (allowing the district court to decline to exercise jurisdictions over certain class actions "in the interests of justice.") The three jurisdictional exceptions of § 1332(d)(9) are the only exceptions that double as restrictions on appellate jurisdiction. See Cardarelli, 527 F.3d at 29 n. 1.
[4]  When we have appellate jurisdiction to review one ruling, we have discretion to exercise pendent jurisdiction over related rulings, otherwise unappealable, that are "`inextricably intertwined' with an issue over which the court properly has appellate jurisdiction." Lamar Adver. of Penn, LLC v. Town of Orchard Park, N. Y., 356 F.3d 365, 371 (2d Cir.2004), quoting Swint v. Chambers County Comm'n, 514 U.S. 35, 50-51, 115 S.Ct. 1203, 131 L.Ed.2d 60 (1995). For instance, appellate jurisdiction exists over non-appealable interlocutory orders when resolving them is necessary to resolve other properly appealable orders. See, e.g., Luna v. Pico, 356 F.3d 481, 486-87 (2d Cir.2004). We have consistently recognized, however, that "pendent appellate jurisdiction should be exercised sparingly, if ever." Bolmer v. Oliveira, 594 F.3d 134, 141 (2d Cir.2010), quoting Mancuso v. N.Y. State Thruway Auth., 86 F.3d 289, 292 (2d Cir. 1996). Here, the issues presented by defendants' two jurisdictional arguments are distinct, and resolving defendants' claim for federal question jurisdiction is not necessary to the resolution of defendants' claim to CAFA jurisdiction. Accordingly, this is not an appropriate case for the exercise of pendent appellate jurisdiction.
[5]  That exception is set out in 28 U.S.C. § 1332(d)(9)(B), discussed in note 2 above.
