See 28 U.S.C. § 46(d); 2d Cir. Internal Operating Procedure E; United States v. Desimone, 140 F.3d 457, 458-59 (2d Cir.1998).
    
   UNDERHILL, District Judge:

The Commonwealth of Kentucky (“Kentucky” or “the Commonwealth”), through its Attorney General, and Pike County, Kentucky (“the County”) (collectively, “Plaintiffs”) commenced this action in Kentucky state court against Purdue Pharma, L.P.; Purdue Pharma, Inc.; Purdue Frederick Company, Inc.; Purdue Pharmaceuticals, L.P.; and P.F. Laboratories, Inc. (collectively, “Purdue”), alleging that Purdue violated Kentucky law by misleading health care providers, consumers, and government officials regarding the risks of addiction associated with the prescription drug OxyContin, which Purdue manufactures, markets and sells. Purdue removed the action to federal court, arguing inter alia that Plaintiffs’ claims constituted a putative “class action” removable under the Class Action Fairness Act of 2005 (“CAFA”), Pub.L. No. 109-2, 119 Stat. 4 (codified in scattered sections of 28 U.S.C.). Following transfer from the Eastern District of Kentucky to the Southern District of New York, the District Court (Sidney H. Stein, J.) granted Plaintiffs’ motion to remand, concluding it lacked subject-matter jurisdiction because the suit did not meet CAFA’s requirements. Purdue now seeks leave to appeal the remand order under 28 U.S.C. § 1453(c)(1). For the reasons that follow, the petition is DENIED.

I.

Plaintiffs’ state court complaint contained the following allegations. Purdue manufactures and sells OxyContin, an opioid analgesic drug used to manage pain. See Am. Compl., at ¶¶ 23-24. From 1995 to 2001, Purdue promoted OxyContin to health care providers 5 as “less addictive, less subject to abuse and diversion, and less likely to cause tolerance and withdrawal than other pain medications,” despite knowing that such assertions were false or misleading. Id. ¶ 42. According to Plaintiffs, Purdue’s actions prevented Kentuckians from accurately assessing the appropriate uses and risks of OxyContin, and caused physicians to overprescribe OxyContin, which resulted in widespread addiction and other adverse consequences, including death and “the commission of criminal acts to obtain OxyContin.” Id. ¶¶ 2, 68, 84. Kentucky, which covers health care costs for indigent and otherwise eligible residents under its Medicaid and Pharmaceutical Assistance Programs, bore significant additional costs as a result of Purdue’s actions. Similarly, Pike County spent millions of dollars investigating, apprehending, prosecuting, and incarcerating persons who, “due to the fraudulently concealed addictive nature of OxyContin, have resorted to criminal means to continue their addiction.” Id. ¶¶ 4, 8-9.

The complaint indicated that the action was brought pursuant to the Kentucky Attorney General’s authority under state statutory and common law, “including [his] parens patriae authority,” to recover, inter alia, “all the costs the Commonwealth ... incurred in paying excessive and unnecessary prescription costs”; “all the costs expended for health care services and programs associated with the diagnosis and treatment of adverse health consequences of OxyContin use”; and “all the costs consumers have incurred in excessive and unnecessary prescription costs related to OxyContin.” Id. ¶¶ 5-6. Specifically, Plaintiffs asserted the following claims under state law: (1) violation of the Kentucky Medicaid Fraud Statute, KRS §§ 205.8463 and 446.070; (2) violation of KRS § 15.060, which authorizes Kentucky’s Attorney General to institute an action to recover fraudulent claims that have been paid out of the state treasury; (3) violation of the Kentucky False Advertising Statute, KRS §§ 517.030 and 446.070; (4) public nuisance; (5) unjust enrichment and restitution; (6) indemnity; (7) negligence; (8) violations of state antitrust law; (9) strict liability; (10) common-law fraud; (11) conspiracy and concert of action; and (12) punitive damages. In addition to damages based on the Medicaid-related expenses described above, the complaint also sought civil penalties, attorneys’ fees, and equitable and injunctive relief.

Purdue removed the action to federal court, asserting that Plaintiffs’ claims (1) raised federal questions under 28 U.S.C. § 1331; and (2) constituted a disguised “class action” removable under CAFA, 28 U.S.C. §§ 1332(d) and 1453. Following transfer to the United States District Court for the Southern District of New York, Plaintiffs moved to remand, arguing that the District Court lacked subject-matter jurisdiction because all of their claims arose exclusively under state law, and the case otherwise failed to meet CAFA’s requirements. The District Court agreed and granted Plaintiffs’ motion to remand in a published decision. See In re Oxycontin Antitrust Litig., 821 F.Supp.2d 591, 603 (S.D.N.Y.2011). This petition timely followed.

II.

As a general rule, “[a]n order remanding a case ... is not reviewable on appeal or otherwise.” 28 U.S.C. § 1447(d). Section 1453(c)(1), however, carves out a limited exception: “a court of appeals may accept an appeal from an order of a district court granting or denying a motion to remand a class action to the State court from which it was removed if application is made to the court of appeals [within a specified time period].” 28 U.S.C. § 1453(c)(1). Despite this narrow expansion of jurisdiction, we retain discretion over whether to accept such appeals, and our decision “will be guided by consideration of the importance and novelty of the issues raised by the case.” Estate of Pew v. Cardarelli, 527 F.3d 25, 29 (2d Cir.2008); see also Koral v. Boeing Co., 628 F.3d 945, 946 (7th Cir.2011) (providing examples of CAFA cases in which leave to appeal was granted “because the appeal presents novel issues”). But even where a petition presents an “important” CAFA issue, courts have nevertheless denied leave to appeal when a determination can be made, on the basis of the petition alone, that the district court correctly remanded the case. See LG Display Co. v. Madigan, 665 F.3d 768, 771 (7th Cir.2011). That determination inevitably requires delving into the merits, but when assessing removal under CAFA, “the jurisdictional inquiry overlaps with the merits,” id., and “[a]s always, we have jurisdiction to determine our jurisdiction.” Cardarelli, 527 F.3d at 28.

III.

Purdue seeks leave to appeal the District Court’s remand order, insisting this case presents an “important” and “unsettled” question under CAFA — namely, whether parens patriae lawsuits brought by state attorneys general qualify as “class actions” under CAFA. See Defs.’ Pet. For Leave to Appeal, at 1-2. We concede the importance of the question, but in light of recent decisions by our Sister Circuits, we determine that the answer is straightforward. Indeed, every Circuit to consider this precise issue — including the Fourth, the Seventh, the Ninth and, most recently, the Fifth — has reached the same conclusion we reach today: parens patriae suits are not removable as “class actions” under CAFA. See West Virginia ex rel. McGraw v. CVS Pharmacy, Inc., 646 F.3d 169, 172 (4th Cir.2011) (“Because this [parens patriae ] action was brought by the State under state statutes that are not ‘similar’ to Federal Rule of Civil Procedure 23, we conclude that it is not removable under CAFA as a class action.”); Madigan, 665 F.3d at 774 (holding parens patriae action was not removable as a “class action” nor as a “mass action” under CAFA); Washington v. Chimei Innolux Corp., 659 F.3d 842, 848-49 (9th Cir.2011) (“[P ]arens patriae lawsuits are not class actions within the meaning of CAFA....”); Mississippi ex rel. Hood v. AU Optronics Corp., 701 F.3d 796, 798-99, 802-03 (5th Cir.2012) (holding parens patriae action by state attorney general was not removable as a “class action” under CAFA, but was otherwise removable under CAFA’s “mass action” provision). Because this action is not a “class action” within the meaning of CAFA, federal jurisdiction does not exist to hear this case, and Purdue’s petition must be denied.

A.

We begin with the apodictic observation that “federal courts are courts of limited jurisdiction” and, as such, “lack the power to disregard such limits as have been imposed by the Constitution or Congress.” Durant, Nichols, Houston, Hodgson, & Cortese-Costa, P.C. v. Dupont, 565 F.3d 56, 62 (2d Cir.2009) (quotation omitted). Congress has granted district courts original jurisdiction over cases in which there is a federal question, see 28 U.S.C. § 1331, and certain cases between citizens of different states, so long as the requirements of complete diversity and amount in controversy are met, see 28 U.S.C. § 1332.

In tandem with this limited grant of jurisdiction, the “federal removal statute allows a defendant to remove an action to the United States District Court in ‘any civil action brought in a State court of which the district courts of the United States have original jurisdiction.’ ” Bounds v. Pine Belt Mental Health Care Res., 593 F.3d 209, 215 (2d Cir.2010) (quoting 28 U.S.C. § 1441(a)). However, “[i]n light of the congressional intent to restrict federal court jurisdiction, as well as the importance of preserving the independence of state governments, federal courts construe the removal statute narrowly, resolving any doubts against removability.” Lupo v. Human Affairs Int’l, Inc., 28 F.3d 269, 274 (2d Cir.1994) (quotation omitted).

CAFA “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.” Greenwich Fin. Servs. Distressed Mortg. Fund 3 LLC v. Countrywide Fin. Corp., 603 F.3d 23, 26 (2d Cir.2010). In general, CAFA amended the diversity statute to confer federal jurisdiction over certain class actions where: (1) the proposed class contains at least 100 members (the “numerosity” requirement); (2) minimal diversity exists between the parties, (i.e., where “any member of a class of plaintiffs is a citizen of a State different from any defendant”); and (3) the aggregate amount in controversy exceeds $5,000,000. 28 U.S.C. § 1332(d)(2)-(6).

CAFA’s reach, however, is limited in the first instance to actions that qualify as either a “class action” or a “mass action.” See 28 U.S.C. § 1332(d)(1)-(2), (11); 28 U.S.C. § 1453(b). CAFA defines the term “class action” as “any civil action filed under rule 23 of the Federal Rules of Civil Procedure or similar State statute or rule of judicial procedure authorizing an action to be brought by 1 or more representative persons as a class action.” 28 U.S.C. § 1332(d)(1)(B). A “mass action,” in contrast, is defined as “any civil action ... in which monetary relief claims of 100 or more persons are proposed to be tried jointly on the ground that the plaintiffs’ claims involve common questions of law or fact, except that jurisdiction shall exist only over those plaintiffs whose claims in a mass action satisfy the jurisdictional amount requirements under subsection (a).” 28 U.S.C. § 1332(d)(11(B)(i). Actions that fail to fit into one of these two statutory categories will fall outside CAFA’s jurisdictional orbit, regardless whether they meet the other prerequisites of numerosity, minimal diversity, and amount in controversy.

B.

Purdue removed this action as a purported “class action” under CAFA. The threshold inquiry, therefore, is whether this action meets CAFA’s definition of a “class action.” We begin our analysis, as we must, with the plain language of the statute. See Conn. Nat’l Bank v. Germain, 503 U.S. 249, 253-54, 112 S.Ct. 1146, 117 L.Ed.2d 391 (1992) (“[I]n interpreting a statute, a court should always turn first to [this] one, cardinal canon before all others.... When the words of a statute are unambiguous, then, this first canon is also the last: judicial inquiry is complete.”) (quotation omitted). As noted above, CAFA defines a “class action” as “any civil action filed under rule 23 of the Federal Rules of Civil Procedure or similar State statute or rule of judicial procedure authorizing an action to be brought by 1 or more representative persons as a class action.” 28 U.S.C. § 1332(d)(1)(B) (emphasis added). “While the statutory definition is, to some degree, circular,” CVS Pharmacy, Inc., 646 F.3d at 174, it is nonetheless unambiguous. See Chimei Innolux Corp., 659 F.3d at 848 (“There is no ambiguity in CAFA’s definition of class action.”). To qualify as a “class action” within the meaning of CAFA, the action must be filed under a statute or rule that is both similar to Rule 23 and authorizes the action to proceed “as a class action.” See id. Because Plaintiffs’ state-court complaint was not filed under Federal Rule of Civil Procedure 23, we must consider whether the suit was “filed under” a state statute or rule of judicial procedure “similar” to Rule 23 that authorizes a class action.

l.

States generally file suit in federal court in one of three capacities: (1) “proprietary suits in which the State sues much like a private party suffering a direct, tangible injury”; (2) “sovereignty suits requesting adjudication of boundary disputes or water rights”; or (3) “parens patriae suits in which States litigate to protect ‘quasi-sovereign’ interests.’ ” Connecticut v. Cahill, 217 F.3d 93, 97 (2d Cir.2000) (internal citations omitted). The parens patriae (i.e., “parent of the country”) doctrine has its antecedent in the common-law concept of the “royal prerogative,” that is, the king’s inherent power to act as the guardian for those “under legal disabilities to act for themselves.” Hawaii v. Standard Oil Co., 405 U.S. 251, 257, 92 S.Ct. 885, 31 L.Ed.2d 184 (1972). To assert parens patriae standing, the State (or Commonwealth) must articulate a “quasi-sovereign interest” distinct “from the interests of particular private parties,” such as an “interest in the health and well-being — both physical and economic — of its residents in general.” Alfred L. Snapp & Son, Inc. v. Puerto Rico, 458 U.S. 592, 607, 102 S.Ct. 3260, 73 L.Ed.2d 995 (1982). The State may show such an interest by alleging “injury to a sufficiently substantial segment of its population.” Id. However, “if the State is only a nominal party without a real interest of its own — then it will not have standing under the parens patriae doctrine.” Id. at 600, 102 S.Ct. 3260; see also In re Baldwin-United Corp., 770 F.2d 328, 341 (2d Cir.1985) (“[W]hen the state merely asserts the personal claims of its citizens, it is not the real party in interest and cannot claim parens patriae standing.”).

Here, Plaintiffs claim to bring this suit in both proprietary and parens patriae capacities, seeking: (1) restitution and reimbursement for damages suffered directly by the Commonwealth and the County ■as a result of, inter alia, unnecessary prescriptions costs and Medicaid claims paid out of the state treasury; (2) civil penalties, fines and attorneys’ fees; and (3) equitable and injunctive relief based on “quasi-sovereign interests” in protecting the health and safety of citizens. Specifically, Plaintiffs’ state-court complaint alleged violations of the following state statutes: (1) KRS § 205.8463, Kentucky’s Medicaid Fraud Statute; (2) KRS § 517.030, Kentucky’s False Advertising Statute; and (3) KRS §§ 367.110-300, the antitrust provisions of Kentucky’s Consumer Protection Act. In addition, the complaint alleged the following common law violations: (1) public nuisance; (2) unjust enrichment and restitution; (3) indemnity; (4) negligence; (5) strict liability; and (6) common-law fraud.

Plaintiffs seek to enforce these various claims under two different statutory provisions: (1) KRS § 446.070; and (2) KRS § 15.060. The former provision establishes a general private right of action under state law: “A person injured by the violation of any statute may recover from the offender such damages as he sustained by reason of the violation, although a penalty or forfeiture is imposed for such violation.” KRS § 446.070 (emphasis added). Under Kentucky law, it is well-settled that the Commonwealth is itself a “person” with standing to bring an action under KRS § 446.070 through its Attorney General. See United States v. Kentucky Nat'l Ins. Co., No. 89-6246, 1990 WL 78173, at *2 (6th Cir. June 11, 1990) (unpublished) (“Kentucky’s highest court [has] held that the state itself, as a body-politic, is a ‘person’ that can maintain an action under KRS 446.070.”) (citing Commonwealth v. Shouse, 245 S.W.2d 441, 442 (Ky.1952)). The latter provision provides that the Attorney General shall: “When he believes that any fraudulent, erroneous or illegal fee bill, account, credit, charge or claim has been erroneously or improperly approved, allowed or paid out of the Treasury to any person, institute the necessary actions to recover the same.” KRS § 15.060(2). In combination, these statutes provide the procedural mechanism through which Plaintiffs bring their substantive claims.

None of these statutes, however, authorizes suit “as a class action,” nor does either bear any resemblance to Rule 23. None, for example, imposes any of the familiar hallmarks of Rule 23 class actions; namely, adequacy of representation, numerosity, commonality, typicality, or the requirement of class certification. See, e.g., AU Optronics Corp., 701 F.3d at 799 (holding that state attorney general’s action did not qualify as a “class action” under CAFA because “the [Mississippi Antitrust Act] does not require that suits brought by the State satisfy any requirements that resemble the adequacy, numerosity, commonality, and typicality requirements of class action lawsuits under Rule 23”); cf. Teamsters Local 115 Freight Div. Pension Fund v. Bombardier Inc., 546 F.3d 196, 201-02 (2d Cir.2008) (noting “the preconditions of Rule 23(a) [are] numerosity, commonality, typicality, and adequacy”). Nor do these statutes provide for notice or opt-out rights to protect absentees who may find themselves unknowingly bound by the court’s judgment. Cf. West Virginia ex rel. McGraw v. Comcast Corp., 705 F.Supp.2d 441, 452-54 (E.D.Pa.2010) (holding that lawsuit brought by state attorney general pursuant to state statute that provided for adequate representation, notice and opt-out rights for represented citizens was sufficiently similar to Rule 23 to qualify the action as a “class action” for CAFA purposes). Although Kentucky’s state-law analog to Rule 23 — Kentucky Rule of Civil Procedure (“KRCP”) 23 — specifically provides for these customary class-action procedures, Plaintiffs’ complaint makes no mention of KRCP 23.

“[W]hile a ‘similar’ state statute or rule need not contain all of the other conditions and administrative aspects of Rule 23, it must, at a minimum, provide a procedure by which a member of a class whose claim is typical of all members of the class can bring an action not only on his own behalf but also on behalf of all others in the elass[.]” CVS Pharmacy, Inc., 646 F.3d at 175. Parens patriae actions, however, implicate few if any of these class-like procedures. See id. at 175-77; Madigan, 665 F.3d at 772; see also West Virginia v. Chas. Pfizer & Co., 440 F.2d 1079, 1089 (2d Cir.1971) (distinguishing between the “alternative theories” of parens patriae actions and class actions under Rule 23). This suit, for example, was filed not by a class representative on behalf of similarly-situated plaintiffs, but by the Attorney General on behalf of the sovereign. Unlike private class representatives, “the Attorney General is not designated as a member of the class whose claim would be typical of the claims of class members.” CVS Pharmacy, Inc., 646 F.3d at 176. Instead, the Attorney General is granted “statutory authority to sue in parens patriae and need not demonstrate standing through a representative injury nor obtain certification of a class in order to recover on behalf of individuals.” Chimei Innolux Corp., 659 F.3d at 848. In form as well as function, parens patriae suits lack the equivalency to Rule 23 that CAFA demands. Accordingly, because this action was not “filed under” a state rule or statute “similar” to Rule 23, it does not qualify as a “class action” within the meaning of CAFA. 28 U.S.C. § 1332(d)(1)(B).

2.

Against this straightforward application of CAFA’s statutory prescriptions, Purdue puts forward several arguments in favor of removal — none of which is convincing.

In Purdue’s estimation, there is more to this case than meets the eye. We are therefore urged to look past the pleadings, the named parties, and the stated causes of action to deduce the true nature of this proceeding. By “piercing the pleadings,” and dissecting the complaint claim by claim, Purdue hopes we will conclude that, for certain claims, the “real parties in interest” are not the Commonwealth or the County, but individual consumers for whom the Attorney General is acting, in effect, as a disguised class representative. Purdue buttresses this argument with choice phrases plucked from the complaint — most notably, a single sentence from the “Prayer for Relief,” which seeks “restitution and reimbursement for all prescription costs consumers have incurred in excessive and unnecessary prescription costs related to OxyContin.” Prayer for Relief, at ¶ H (emphasis added). Building on this claim-by-claim approach, Purdue presses us to conclude that CAFA’s requirements for minimal diversity, numer-osity, and amount in controversy are satisfied.

The Supreme Court has held that “the ‘citizens’ upon whose diversity a plaintiff grounds jurisdiction must be real and substantial parties to the controversy.” Navarro Sav. Ass’n v. Lee, 446 U.S. 458, 460, 100 S.Ct. 1779, 64 L.Ed.2d 425 (1980). Accordingly, courts “must disregard nominal or formal parties and rest jurisdiction only upon the citizenship of real parties to the controversy.” Id. at 461, 100 S.Ct. 1779. In determining whether a State is a real party in interest, we have held that “inquiry must be made as to the ‘essential nature and effect of the proceeding.’” Finkielstain v. Seidel, 857 F.2d 893, 895 (2d Cir.1988) (quoting Ford Motor Co. v. Dep’t of Treasury, 323 U.S. 459, 464, 65 S.Ct. 347, 89 L.Ed. 389 (1945)); see also Ferguson v. Ross, 38 F. 161, 162-63 (C.C.E.D.N.Y.1889) (“Courts will look behind and through the nominal parties on the record to ascertain who are the real parties to the suit, and will determine whether a state is the real party to an action brought by or against its officer by a consideration of the nature of the case as presented by the whole record.”) (emphasis added).

As authority for its claim-by-claim approach, Purdue cites Louisiana ex rel. Caldwell v. Allstate Ins. Co., 536 F.3d 418 (5th Cir.2008). In Caldwell, the Fifth Circuit declined to remand an attorney generals antitrust action in which the State sought to collect, under its parens patriae authority, treble damages on behalf of certain citizen-policyholders. Id. at 422-23, 432. Noting that Congress, in passing CAFA, had “emphasized that the term ‘class action’ should be defined broadly to prevent ‘jurisdictional gamesmanship,’ ” id. at 424 (quoting S.Rep. No. 109-14, at 35 (2005), 2005 U.S.C.C.A.N. 3), the court analyzed the real parties in interest on a claim-by-claim basis, rather than looking at the lawsuit as a whole. Id. at 425, 429-30. After carefully considering whether the State or its citizens were the “real parties” with respect to each type of relief sought, the Court “conclude[d] that as far as the State’s request for treble damages is concerned, the policyholders are the real parties in interest,” and the action was therefore properly removed as a “mass action” under CAFA. Id. at 429-30. Relying heavily on Caldwell, and arguing that this action, too, is merely masquerading as a parens patriae action to avoid CAFA’s reach, Purdue invites us to adopt the claim-by-claim approach to unmask the “class action” lurking underneath.

We decline that invitation.

First, Caldwell’s holding addresses only CAFA’s “mass action ” provisions, not the “class action” provisions we encounter here. See Caldwell, 536 F.3d at 430 (“Since we have concluded that this case was properly removed under CAFA’s ‘mass action’ provision, we need not address whether this lawsuit could, following further proceedings on remand, properly proceed as a class action under CAFA.”); see also In re Vioxx Prods. Liab. Litig., 843 F.Supp.2d 654, 660 (E.D.La.2012) (“[T]he Fifth Circuit’s precise holding in Caldwell is limited to the CAFA definition of mass actions, not class actions. The court expressly declined to decide whether the parens patriae lawsuit could also proceed as a class action on remand.... ”). Purdue removed this action as a “class action,” and has never contended that this action qualifies as a “mass action.” Therefore, Caldwell’s reasoning is inappo-site.

Second, we note that the “claim-by-claim” approach has been roundly criticized, and the “whole-complaint” approach has emerged as the majority rule. See, e.g., AU Optronics Corp. v. South Carolina, 699 F.3d 385, 390, 393-94 (4th Cir.2012) (addressing application of CAFA’s “mass action” provisions by “adopting the whole-case approach and rejecting the claim-by-claim approach”); Nevada v. Bank of Am. Corp., 672 F.3d 661, 669-70 (9th Cir.2012) (employing “the approach of looking at the case as a whole to determine the real party in interest, rather than the claim-by-claim approach adopted in Caldwell ”); Madigan, 665 F.3d at 773-74 (rejecting Caldivett’s claim-by-claim approach, noting “just because CAFA was meant to expand federal courts’ jurisdiction over class actions, it does not follow that federal courts are required to deviate from the traditional ‘whole complaint’ analysis when evaluating whether a State is the real party in interest in a parens patriae ease”) (internal quotation omitted); see also Ohio v. GMAC Mortg., LLC, 760 F.Supp.2d 741, 745 (N.D.Ohio 2011) (“[A] majority of jurisdictions ... have looked at a state’s complaint as a whole to determine whether the state is the real-party-in-interest.”).

We have not yet passed on whether the real-party-in-interest inquiry should be made on the basis of the whole complaint or claim by claim, and district courts within this Circuit — considering the issue both before and after CAFA — appear to be split. Some have applied a claim-by-claim approach. See, e.g., Connecticut v. Levi Strauss & Co., 471 F.Supp. 363, 370-71 (D.Conn.1979) (analyzing separately each type of relief sought in the State’s complaint to determine whether the State was the real party in interest for diversity purposes); see also Connecticut v. Chubb Group of Ins. Cos., No. 3:11-cv-997, 2012 WL 1110488, at *3 (D.Conn. Mar. 31, 2012) (following Levi Strauss, 471 F.Supp. at 370-71); Butler v. Cadbury Beverages, Inc., No. 3:97-cv-2241, 1998 WL 422863, at *2 (D.Conn. July 1, 1998) (same). Others have looked to the complaint as a whole. See New York ex rel. Abrams v. General Motors Corp., 547 F.Supp. 703, 704-07 (S.D.N.Y.1982) (looking to “the primary purpose of the action” to determine the real party in interest); MyInfoGuard, LLC v. Sorrell, Nos. 2:12-cv-074, 2:12-cv-102, 2012 WL 5469913, at *4-5 (D.Vt. Nov. 9, 2012) (rejecting Caldwell and stating “[t]his Court adopts the wholesale approach”); Connecticut v. Moody’s Corp., No. 3:10-cv-546, 2011 WL 63905, at *3 (D.Conn. Jan. 5, 2011) (considering “the State’s stake in the litigation as a whole”); New York ex rel. Cuomo v. Charles Schwab & Co., Inc., No. 09-cv-7709, 2010 WL 286629, at *4-6 (S.D.N.Y. Jan. 19, 2010) (same).

But we need not decide that issue today. Whatever the comparative merits of a “claim-by-claim” versus “whole-complaint” approach for purposes of determining diversity, the real-party-in-interest analysis has no bearing on the separate — and ultimately dispositive — question whether this suit qualifies as a “class action” under CAFA (i.e., whether the suit is “filed under” a statute or rule “similar” to Rule 23 and authorizing suit “as a class action,” 28 U.S.C. § 1332(d)(1)(B)). Even assuming that consumers are the “real parties” for certain discrete claims asserted by the Attorney General, that simply means that the citizenship of those consumers — rather than the “non-citizenship” of the State, see Stone v. South Carolina, 117 U.S. 430, 433, 6 S.Ct. 799, 29 L.Ed. 962 (1886) (“[A] state cannot, in the nature of things, be a citizen of any state.”) — counts for purposes of meeting CAFA’s minimal diversity requirement. See Lee, 446 U.S. at 460, 100 S.Ct. 1779 (“[T]he ‘citizens’ upon whose diversity a plaintiff grounds jurisdiction must be real and substantial parties to the controversy.”). But that determination does not necessarily negate the parens-patriae nature of the action, of. Fed. R.Civ.P. 17(a)(1) (parties “authorized by statute” may “sue in their own names without joining the person for whose benefit the action is brought”), nor does it transform the action into a “class action” removable under CAFA. Having concluded, in the first instance, that this parens patriae action is not a “class action” within the plain meaning of CAFA, our inquiry is at an end. We need not “pierce the pleadings” any further, particularly in light of the Supreme Court’s directive to construe removal statutes strictly and resolve doubts in favor of remand. See Syngenta Crop Protection, Inc. v. Henson, 537 U.S. 28, 32-33, 123 S.Ct. 366, 154 L.Ed.2d 368 (2002); see also Franchise Tax Bd. v. Constr. Laborers Vacation Trust, 463 U.S. 1, 21 n. 22, 103 S.Ct. 2841, 77 L.Ed.2d 420 (1983) (noting 18 that, out of “considerations of comity,” federal courts should be “reluctant to snatch cases which 19 a State has brought from the courts of that State, unless some clear rule demands it”).

One final point. Our decision today merely concerns CAFA’s jurisdictional reach over this action, not whether the action is otherwise sufficient as a matter of state law. Whether Plaintiffs may proceed and ultimately recover on their claims presents complex questions of Kentucky law, which we only see through Erie’s glass darkly, and upon which we express no opinion.

IV.

In sum, the District Court correctly determined that Plaintiffs’ action is not a “class action” as defined in CAFA, and therefore the case was properly remanded. The petition for leave to appeal is DENIED. 
      
      . Other courts presented with a petition under section 1453(c)(1) have taken a slightly different path to reach a similar result. Some have granted leave to appeal and decided the merits of the appeal in a single decision. See AU Optronics Corp. v. South Carolina, 699 F.3d 385, 394 (4th Cir.2012). Others have granted leave to appeal, permitted the parties to submit additional merits briefing, and then affirmed the remand order in a separate decision. See, e.g., West Virginia ex rel. McGraw v. CVS Pharmacy, Inc., 646 F.3d 169, 173, 179 (4th Cir.2011); Washington v. Chimei Innolux Corp., 659 F.3d 842, 850 (9th Cir.2011). Here, because the parties have fully briefed the CAFA-related issues raised in this petition, we follow the Seventh Circuit's approach in Madigan for the sake of efficiency.
     
      
      . To the extent that leave to appeal is granted on the CAFA-related issues under section 1453(c)(1), Purdue also seeks review of non-CAFA-related issues addressed in the District Court’s remand order; namely, whether the Commonwealth’s claims for recovery of Medicaid expenditures raise a question of federal law sufficient to confer jurisdiction under 28 U.S.C. § 1331. See Defs.’ Pet. For Leave to Appeal, at 14. Because we decline to grant leave to appeal the CAFA-related issues, we lack jurisdiction over the others. See 28 U.S.C. § 1447(d).
     
      
      . The definition of "mass action” specifically excludes class actions certified or proposed to be certified under Rule 23. See 28 U.S.C. § 1332(d)(11)(B), (C)(ii). But CAFA adds a rather confusing semantic twist: "For purposes of this subsection and section 1453, a mass action shall be deemed to be a class action removable under paragraphs (2) through (10) if it otherwise meets the provisions of those paragraphs.” 28 U.S.C. § 1332(d)(11)(A) (emphasis added). This "peculiar” drafting, wrote one Court, "gives mass actions the character of a kind of statutory Janus; under CAFA, a mass action simultaneously is a class action (for CAFA’s purposes) and is not a class action (in the traditional sense of Rule 23 and analogous state law provisions).” Lowery v. Alabama Power Co., 483 F.3d 1184, 1195 n. 27 (11th Cir.2007). We note this statutory peculiarity merely to clarify that, for purposes of this opinion, “class actions” and "mass actions” axe two distinct categories. Thus, where we refer to "class actions” under CAFA, we mean class actions as defined by section 1332(d)(1)(B), not the more inclusive definition under section 1332(d)(11)(A).
     
      
      . Purdue does not contend that this action qualifies as a "mass action” under CAFA. See Defs.’ Pet. For Leave to Appeal, at 6 ("Purdue properly removed this action under CAFA because Kentucky consumers are real parties in interest to this case and the claims brought on their behalf are governed by a state rule of procedure 'authorizing an action to be brought by 1 or more representative persons as a class action.' ” (quoting 28 U.S.C. § 1332(d)(1)(B))). Therefore, we need not — and do not — address today whether this action could otherwise qualify as a "mass action.” We do note, however, that the statutory definition of "mass action” explicitly excludes actions that, inter alia, assert claims "on behalf of the general public (and not on behalf of individual claimants or members of a purported class) pursuant to a State statute specifically authorizing such action.” 28 U.S.C. § 1332(d)(11)(B)(ii)(III).
     
      
      . Indeed, CAFA's statutory language seems to imply, albeit obliquely, that the term "class actions” refers to actions subject to some form of class certification process. See 28 U.S.C. § 1332(d)(1)(D) ("[T]he term ‘class members’ means the persons (named or unnamed) who fall within the definition of the proposed or certified class in a class action.”) (emphasis added); see also 28 U.S.C. § 1332(d)(ll)(C)(ii).
     
      
      . Purdue also argues that, although the complaint contains no express reference to KRS § 367.200 or KRCP 23, a careful review of the claims raised therein reveals that the Attorney General is actually relying, albeit surreptitiously, on those provisions to assert representative claims for restitution on behalf of individual consumers. Building on that premise, Purdue argues that, because none of the statutes cited in the complaint specify the procedural mechanisms through which such representative claims are brought, KRS § 367.200 and KRCP 23 automatically apply to fill the gap.
      To the extent we understand this serpentine line of reasoning, we disagree. Under CAFA’s plain language, a "class action” is defined as a civil action “filed under ” a state-law equivalent to Rule 23. 28 U.S.C. § 1332(d)(1)(B) (emphasis added). Neither KRS § 367.200 nor KRCP 23 are mentioned anywhere in Plaintiffs' complaint, and we are hard pressed to understand how a suit may be "filed under" a statute or rule that does not even appear on the face of the complaint. See In re Vioxx Prods. Liab. Litig., 843 F.Supp.2d 654, 664 (E.D.La.2012) ("Congress chose to define 'class action’ not in terms of joinder of individual claims or by representative relief in general, but in terms of the statute or rule the case is filed under.... If this is a formalistic outcome, it is a formalism dictated by Congress.”). Moreover, the mere fact that the Attorney General could have utilized some other statutory or procedural mechanism to recover restitution is beside the point. Plaintiffs, as masters of their complaint, are always free to choose the statutory provisions under which they will bring their claims. See The 
        
        Fair v. Kohler Die & Specialty Co., 228 U.S. 22, 25, 33 S.Ct. 410, 57 L.Ed. 716 (1913) (“Of course, the party who brings a suit is master to decide what law he will rely upon[.]”). Purdue’s argument is therefore unavailing.
     
      
      . Conceding, as it must, that Plaintiffs’ enforcement-related claims for civil penalties, equitable and injunctive relief, and damages due the Commonwealth are properly brought pursuant to the Commonwealth’s proprietary and parens patriae authority, Purdue nonetheless relies on the ‘ 'claim-by-claim” approach to argue that Plaintiffs are not the real parties in interest for restitution claims allegedly brought on behalf, and for the benefit, of a circumscribed group of consumers. Putting aside for the moment our skepticism that a real-party-in-interest analysis is appropriate under the circumstances of this case, we nevertheless take issue with Purdue’s narrow characterization of Plaintiffs’ allegations. Even assuming the complaint seeks certain remedies that could be characterized as class relief, the overall thrust of the complaint is to bring a single action by the sovereign to protect the health and welfare of its residents in general, not to maintain all of their individual claims as a class action.
     
      
      . Purdue likely had good reason to remove this action solely as a "class action,” and not as a "mass action.” Shortly after filing its notice of removal, Purdue moved to transfer this case from the Eastern District of Kentucky to the Southern District of New York for inclusion in the Multi-District Litigation ("MDL”) Court (In re Oxycontin Antitrust Litigation), No. 04-MDL-1603 (SHS). Although CAFA permits defendants to remove state-court actions as either a class action or a mass action, a removed mass action cannot be transferred to an MDL Court — as Purdue did here — without the consent of a majority of the plaintiffs. See 28 U.S.C. § 1332(d)(l l)(C)(i) ("Any action(s) removed to Federal court pursuant to [section 1332(d)(l 1) ] shall not thereafter be transferred to any other court pursuant to section 1407, or the rules promulgated thereunder, unless a majority of the plaintiffs in the action request transfer pursuant to section 1407.”).
     
      
      . We note that, under the circumstances of this case, minimal diversity appears to be met as a result of Pike County's presence as a party-plaintiff. See Illinois v. City of Milwaukee, 406 U.S. 91, 97, 92 S.Ct. 1385, 31 L.Ed.2d 712 (1972) (“It is. well settled that for the purposes of diversity of citizenship, political subdivisions are citizens of their respective States.”). Thus, at least one plaintiff is diverse from one defendant. See 28 U.S.C. § 1332(d)(2)(A).
     
      
      . Indeed, even if we were to determine that Plaintiffs lacked parens patriae standing altogether — a question we do not reach today, see CPS Pharmacy, Inc., 646 F.3d at 176 n. 2 ("[WJhile we conclude that this action is a parens patriae action, based on the State’s deterrence and consumer protection interests, that conclusion is not essential to the separate, and more meaningful determination that the action in this case was not brought under a procedure 'similar' to Rule 23.”) — that determination would leave Plaintiffs not with a “class action” removable under CAFA, but with no justiciable action at all.
