OPINION
delivered the opinion of the Court,
The plaintiffs, commercial and residential consumers of natural gas, purchased natural gas from utilities, which had ac *848 quired the product wholesale from the defendants. In this class action antitrust suit, the plaintiffs allege that the defendants engaged in various anti-competitive practices, including making false statements about natural gas transactions and engaging in “wash trades” and “churning.” After the defendants filed a motion to dismiss, contending that the claims were barred by both field pre-emption and the filed rate doctrine, the chancellor dismissed the claims. The plaintiff appealed and the Court of Appeals reversed, holding that the claims were not subject to dismissal. Because the Natural Gas Act and subsequent federal legislation pre-empt state actions in this particular field of regulation, the judgment of the Court of Appeals is reversed and all claims are dismissed.
Facts and Procedural History 1
This litigation represents a single component of a complex, nationwide effort by consumers and other purchasers challenging the pricing practices of wholesalers of natural gas. Williams Companies, Inc., Williams Energy Marketing & Trading Company, Inc., Williams Merchant Services, Reliant Energy Services, Inc., Reliant Energy, Inc., ONEOK, Inc., ONEOK Energy Marketing and Trading Company, L.P., Dynegy Marketing & Trade, CMS Energy Corporation, CMS Field Services, CMS Marketing Services & Trading Company, El Paso Corporation, El Paso Merchant Energy, LP, Duke Energy Corporation, Duke Energy Trading and Marketing Company, LLC, American Electric Power Co., and AEP Energy Services, Inc. (the “Defendants”) sold natural gas at wholesale to Tennessee utilities (the “Utilities”), which then sold the product at retail to a variety of individuals and businesses in Tennessee, including Samuel D. Leggett, Frank H. Colvett, Jr., Bing’s Stop & Shop, Wolfe River Café, and others, who make up the class filing this suit (the “Plaintiffs”). The Plaintiffs claim that, from at least January 1, 2000, through October 31, 2002, the Defendants engaged in a pervasive and widespread scheme to artificially inflate the price of wholesale natural gas, and that the Utilities passed along those costs to the Plaintiffs.
Reporting firms such as Platts, a division of the McGraw-Hill Companies, gather information about volume and pricing from those in the natural gas market and publish indices reflecting their data, such as Gas Daily and the monthly Inside FERC Gas Market Report (“IFERG”). In turn, natural gas sellers, purchasers, and futures traders rely on the indices to evaluate market conditions and set prices. The Plaintiffs allege that the various Defendants reported thousands of natural gas trades to these firms containing false or misleading information designed to influence the price of gas in their favor. The Plaintiffs contend that, as a part of their efforts to manipulate pricing, the Defendants reported sales that did not exist, failed to report sales that did occur, and reported actual sales accompanied by false information regarding the volume and the price.
The Plaintiffs further assert that certain of the Defendants engaged in “wash trades” and “churning” in an effort to inflate the price of natural gas. “A wash trade is a transaction where two parties simultaneously buy and sell the same quantity of natural gas at the same price and on the same day[,] creatpng] a false apрearance of demand for and short sup
*849
ply of natural gas.”
E. & J. Gallo Winery v. EnCana Corp.,
All in all, the Plaintiffs contend that more than three-quarters of the trades reported to three of IFERC’s “trading desks,” 2 as well as thousands of trades reported to Gas Daily, were false, misleading, or knowingly inaccurate. Since 2002, several of the Defendants have been subjected to civil penalties associated with false reporting and market manipulation. For example, ONEOK, Inc. and ONEOK Energy Marketing and Trading Company, L.P. each paid $3 million in penalties to the Commodity Futures Trading Commission (the “CFTC”) in October of 2002; Dynegy Marketing and Trade and non-party West Coast Power LLC paid $5 million to the CFTC in December of 2002; El Paso Corporation and El Paso Merchant Energy, LP paid $20 million in penalties to the CFTC in March of 2003; Williams Companies, Inc., and Williams Energy Marketing & Trading Company, Inc., paid $20 million in civil penalties to the CFTC in July of 2003; Duke Energy Corporation and Duke Energy Trading and Marketing Company, LLC, paid $28 million to the CFTC in September of 2003; CMS Energy Corporation, CMS Marketing Services & Trading Company, and CMS Field Services paid $16 million to the CFTC in November of 2003; during the same month, Reliant Energy Services, Inc. 3 paid $18 million to the CFTC; and American Electric Power Company and AEP Energy Services, Inc., paid $30 million to the CFTC in January of 2005. Further, AEP Energy Services, Inc., paid an additional $30 million to the United States Department of Justice.
In January of 2005, the Plaintiffs filed a complaint for damages under the Tennessee Trade Practices Act (“TTPA”) alleging an unlawful conspiracy to increase the wholesale price of natural gas. Later, the case was removed to federal court and referred to a Multi-District Litigation Panel, which assigned the suit to the U.S. District Court for the District of Nevada. The Defendants sought a dismissal for failure to state a claim, but before ruling on the motion, the district court remanded the case to the Chancery Court of Fayette County. On September 18, 2006, the Plaintiffs filed a motion for class certification in the chancery court, seeking certification for two subclasses — first, the “Indirect Residential Class,” as represented by Leggett and Colvett, and secondly, the “Indirect Business Class,” as represented by Bing’s Stop & Shop and Wolfe River Café. See generally Tenn. R. Civ. P. 23 *850 (governing class actions). They defined the proposed subclasses as follows:
Indirect Residential Class
All persons in Tennessee who made indirect purchases of natural gas from any municipality (city, town, or county) or any utility district for a residence, household, apartment, or place of dwelling at any time during the period January 1, 2000 through October 31, 2002. Excluded from the class are indirect business purchasers of any municipality or utility district, direct purchasers, federal government agencies, defendants, defendants’ affiliates, or sellers or resellers of natural gas.
Indirect Business Class
All persons, partnerships, associations, private firms, public entities, corporations, and other business entities in Tennessee who made indirect purchases of natural gas from any municipality (city, town, or county) or any utility district for use by their business at any time during the period January 1, 2000 through October 31, 2002. Excluded from the class are indirect residential purchasers of any municipality or utility district, direct purchasers, federal government agencies, defendants, defendants’ affiliates, or sellers or resellers of natural gas.
Afterward, the Defendants renewed the motion to dismiss that had initially been filed in the federal district court, arguing first that under the “filed rate doctrine,” the cause of action, if allowed to proceed, would invade the exclusive rate-making authority of the Federal Energy Regulatory Commission (“FERC”); and, in the alternative, that any state cause of action would be pre-empted insofar as it applied to “the field of transportation and sales of natural gas in interstate commerce,” regardless of whether it specifically violated the filed rate doctrine. In response, the Plaintiffs asserted that the prices at issue were never filed with FERC and thus were not subject to the filed rate doctrine and, further, that pre-emption applies only to wholesale natural gas sales, and the Plaintiffs were retail-level customers. 4 The Defendants, in reply, claimed that the filed rate doctrine continues to apply even when deregulation has ended the practice of formally filing rates, if the rates remain subject to federal policy. In addition, they contended that although the Plaintiffs were retail customers, the conduct at issue occurred in the wholesale market, and thus within the field pre-empted by federal governance. The chancellor conducted a hearing on the motion, and afterwards, both the Plaintiffs and the Defendants filed supplemental pleadings.
On February 2, 2007, at the closing of a subsequent hearing on issues relating to jurisdiction, the chancellor concluded that the claims were barred by federal preemption and dismissed the complaint:
[O]nce the [Natural Gas Act] began the regulation [of pricing of natural gas wholesales in the interstate market], ... the United States [government kept it. They had the ability to regulate it. Nobody else had the ability to regulate it. And therefore that regulation is still under the United States [g]overnment, and ... if it’s ... under the auspices of the [f]ederal [g]overnment, this [s]tate [c]ourt has absolutely no authority to do anything concerning ... the change in the rates of the wholesale gas. That’s *851 up to the [f]ederal [government. They regulate it; you go to them.
On appeal by the Plaintiffs, the Court of Appeals reversed, relying heavily on
E. & J. Gallo Winery,
[W]e find that the trial court erred in concluding that all of the Tennessee Purchasers’ claims were preempted by federal law.... [S]ome of the transactions may be subject to FERC’s exclusive jurisdiction, some may not be. From the record before us, it is impossible to make a definitive determination. Because FERC’s jurisdiction is predicated upon the nature of each transaction, it was premature to dismiss the case at this early stage of the lawsuit.

Analysis
I. The Tennessee Trade Practices Act
The Tennessee Trade Practices Act (“TTPA”), Tenn.Code Ann. §§ 47-25-101 to -112 (2001), is a general antitrust statute establishing that various anticompetitive practices are “against public policy, unlawful, and void” in the State of Tennessee. Tenn.Code Ann. §§ 47-25-101, -102. 5 Tennessee Code Annotated section 47-25-106 creates a private cause of action for persons harmed by violations of the TTPA:
Any person who is injured or damaged by any such arrangement, contract, agreement, trust, or combination described in this part may sue for and recover, in any court of competent jurisdiction, from any person operating such trust or combination, the full consideration or sum paid by the person for any goods, wares, merchandise, or articles, the sale of which is controlled by such combination or trust.
In
Freeman Industries, LLC v. Eastman Chemical Co.,
we held that “indirect purchasers” may recover under Tennessee Code Annotated section 47-25-106.
II. Pre-emption
Article VI, paragraph 2 of the United States Constitution (the “Supremacy Clause”) provides as follows:
*853 This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.
(Emphasis added.) Pursuant to the Supremacy Clause, federal law sometimes pre-empts otherwise permissible state laws, rendering the state laws without force.
E.g., Riegel v. Medtronic, Inc.,
Courts have historically recognized both “express pre-emption” and “implied pre-emption.” Express pre-emption occurs when Congress “define[s] explicitly the extent to which its enactments preempt state law.”
English v. Gen. Elec. Co.,
Even when there is no explicit textual reference to pre-empting state law, pre-emption may be implicit.
See Geier v. Am. Honda Motor Co.,

III. History of the State/Federal Relationship in Natural Gas
Federal regulation of the natural gas market has had a unique and storied history. On several occasions, the United States Supreme Court has considered the extent of state regulatory authority on the subject. A synopsis of the history may provide context for our consideration of the issues presented in this litigation.
A. The ‘Attleboro Doctrine” and the Natural Gas Act of 1938
A 1925 breakthrough in pipeline technology triggered a boom in the interstate natural gas market. Dozier A. DeVane,
Highlights of Legislative History of the Federal Power Act of 1935 and the Natural Gas Act of 1938,
14 Geo. Wash. L.Rev.
*855
30, 31 (1945-46). Even before that, however, the Supreme Court had already laid the groundwork for its treatment of an interstate natural gas market. In
West v. Kansas Natural Gas Co.,
the Court considered various challenges to a 1907 Oklahoma statute (1) forbidding out-of-state corporations from engaging in their natural gas market and (2) denying “a charter or right of eminent domain, or right to use the highways of this state” to any corporation transmitting natural gas unless the charter “expressly stipulated” that it would neither transport nor transmit the gas out of the state, nor provide the gas to any “individuals, associations, copartnership companies, or corporations engaged in transporting or furnishing natural gas ... outside of th[e] State.”
[Tjhis overlooks the affirmative force of the interstate commerce clause of the Constitution. The inaction of Congress is a declaration of freedom from state interference with the transportation of articles of legitimate interstate commerce, and this has been the answer of the courts to contentions like those made in the case at bar.
Id.
at 261,
Although the
West
decision signaled the Court’s willingness to provide a constitutional framework for distinguishing between state and federal interests in the field of natural gas, it did not draw a bright line for those states having legislation less transparently protectionist than the Oklahoma statute. In
Public Utilities Commission for Kansas v. Landon,
That the transportation of gas through pipe lines from one State to another is interstate commerce may not be doubted.... But in no proper sense can it be said, under the facts here disclosed, that sale and delivery of gas to their customers at burner-tips by the local companies operating under special franchises constituted any part of interstate commerce. The companies received supplies which had moved in such commerce and then disposed thereof at retail in due course of their own local business.... Interstate movement ended when the gas passed into local mains.
Id.
at 245,
In 1924, the Court, relying on its Landon decision, struck down Kansas and Missouri laws asserting power to regulate rates for upstream sales of natural gas:
[The] sale and delivery ... to ... customers at retail is intrastate business and subject to state regulation. In such case the effect on interstate commerce, if there be any, is indirect and incidental. But the sale and delivery here is an inseparable part of a transaction in interstate commerce — not local, but essentially national, in character- — -and enforcement of a selling price in such a transaction places a direct burden upon such commerce inconsistent with that freedom of interstate trade which it was the purpose of the commerce clause to seсure and preserve.
Missouri ex rel. Barrett v. Kan. Natural Gas Co.,
The contention that, in the public interest, the business is one requiring regulation, need not be challenged. But Congress thus far has not seen fit to regulate it, and its silence, where it has the sole power to speak, is equivalent to a declaration that that particular commerce shall be free from regulation....
[[Image here]]
The paramount interest is not local but national, admitting of and requiring uniformity of regulation. Such uniformity, even though it be the uniformity of governmental nonaction, may be highly necessary to preserve equality of opportunity and treatment among the various communities and States concerned.
Barrett,

doctrine problematic in the eyes of both Congress and the public. By 1928, Congress had adopted a resolution authorizing the Federal Trade Commission to investigate the electricity and natural gas industries, despite opposition from the industries themselves. S. Res. 83, 70th Cong., 1st Sess. (1928);
see
DeVane,
The NGA defined its scope as follows:
The provisions of this Act shall apply to the transportation of natural gas in interstate commerce, to the sale in interstate commerce of natural gas for resale for ultimate 'public consumption for ... any ... use, and to natural-gas companies engaged in such transportation or sale, but shall not apply to any other transportation or sale of natural gas or to the local distribution of natural gas or to the facilities used for such distri-btotion or to the production or gathering of natural gas.
NGA § 1(b) (emphasis added). The act required that the prices for the regulated gas sales be filed with and approved by the Federal Power Commission (“FPC”) (later FERC). NGA §§ 2(9), 4.
The original purpose of the NGA, which was restricted to the regulation of interstate sales for resale, was to fill the gap in natural gas regulation created by the At-tleboro doctrine:
An avowed purpose of the Natural Gas Act of June 21, 1938, was to afford, through the exercise of the national power over interstate commerce, an agency for regulating the wholesale distribution to public service companies of natural gas moving interstate, which this Court had declared to be interstate commerce not subject to certain types of state regulation.
Ill. Natural Gas Co. v. Cent. Ill. Pub. Serv. Co.,
The Attleboro doctrine itself, however, soon fell out of favor as a rule of constitutional law. In Illinois Natural Gas Co., the Supreme Court observed that its prior rulings endorsing the Attleboro doctrine were in conflict with the rationale expressed in other decisions pertaining to the dormant Commerce Clause doctrine and implied that, if the NGA had not rendered the wholesale/resale distinction in natural gas a question of statutory law, it might reconsider the Attleboro doctrine altogether:
In the absence of any controlling act of Congress, we should now be faced with the question whethеr the [test set forth in non-Attleboro cases] is a more reliable touchstone for ascertaining state power than the mechanical distinctions on which appellee relies. But we are under no necessity of making that choice here, for Congress, by the Natural Gas Act, has brought under national control the very matters which the state has undertaken to regulate [in this case],
B. Pre-Emption Under the NGA
In the years following its enactment, the Supreme Court began to consider the degree to which the NGA pre-empted state law.
See, e.g., Natural Gas Pipeline Co. of Am. v. Panoma Corp.,
The Supreme Court reversed, employing a classic field pre-emption rationale:
Thе Congress enacted a comprehensive scheme of federal regulation of “all wholesales of natural gas in interstate commerce, whether by a pipeline company or not and whether occurring before, during, or after transmission by an interstate pipeline company.”
The federal regulatory scheme leaves no room either for direct state regulation of the prices of interstate wholesales of natural gas, or for state regulations which would indirectly achieve the same result.
Northern Natural,
C. Deregulation and the Transcon Era
In the 1970s, the United States experienced a natural gas shortage that has been widely attributed to the supply-suppressing effects of the NGA’s stringent price controls.
Pub. Serv. Comm’n v. Mid-La. Gas Co.,
The Supreme Court quickly confirmed that field pre-emption survived the enactment of the NGPA, at least in some form. In
Exxon Corp. v. Eagerton,
for example, several natural gas producers challenged an Alabama law prohibiting them from passing the state severance tax along to consumers. While conceding that there was no direct conflict between the pass-through prohibition and the NGPA,
id.
at 183,
The Alabama pass-through prohibition trespassed upon FERC’s authority over wholesale sales of gas in interstate commerce, for it barred gas producers from increasing their prices to pass on a particular expense — the increase in the severance tax- — to their purchasers. Whether or not producers should be permitted to recover this expense from *861 their purchasers is a matter within the sphere of FERC’s regulatory authority.
Id.
at 185,
In
Transcontinental Gas Pipe Line Corp. v. State Oil & Gas Board, (“Transcon
”) the Court went a step further, holding that field pre-emption under the NGPA extended even to high-cost gas sales that had been deregulated.
In a 5-4 decision, the Supreme Court reversed, observing, as an initial matter, that based on content and legislative history, the NGPA did not signal a retreat from a comprehensive federal gas policy and, “in some respects expanded federal control, since it granted FERC jurisdiction over the intrastate market for the first time.”
Transcon,
The proper question in this case is not whether FERC has affirmative regulatory power over wellhead sales of [deregulated] gas, but whether Congress, in revising a comprehensive federal regulatory scheme to give market forces a more significant role in determining the supply, the demand, and the price of natural gas, intended to give the States the power it had denied FERC. The answer to the latter question must be in the negative. First, when Congress meant to vest additional regulatory au *862 thority in the States it did so explicitly. Second, although FERC may now possess less regulatory jurisdiction over the “intricate relationship between the purchasers’ cost structures and eventual costs to wholesale customers who sell to consumers in other States,” than it did under the old regime, that relationship is still a subject of deep federal concern. FERC still must review Transco’s pricing practices, even though its review of Transco’s purchasing behavior has been circumscribed. In light of Congress’ intent to move toward a less regulated national natural gas market, its decision to remove jurisdiction from FERC cannot be interpreted as an invitation to the States to impose additional regulations.
Id,,
at 422-23,
Two years later, the Court had the opportunity to clarify the full scope of preemption under
Northern Natural
and
Transcon.
A Michigan statute (“Act 144”) required certain natural gas companies to obtain approval from the Michigan Public Service Commission (“MPSC”) before issuing long-term securities. As part of the approval process, the MPSC was empowered to “conduct an investigation, including an appraisal of the company’s property at the company’s expense.”
Schneidewind,
Even if Commerce Clause jurisprudence would have barred Act 144’s regulation at the time of the enactment of the NGA, an issue never directly settled by the Court, that would not decide this case. The authorities on which respondents rely state only [that] Congress occupied the field of matters relating to wholesale sales and transportation of natural gas in interstate commerce. The question remains, however, whether Act 144 regulates within this exclusively federal domain.... An intent to preempt state regulation thus cannot be inferred from the mere fact that States were precluded from such regulation at the time of the NGA’s enactment.
Id.
at 305-06,
The Court concluded that the “crux of the issue” was “whether Act 144 is a regulation of the rates and facilities of natural gas companies used in transportation and sale for resale of natural gas in interstate commerce. Since ... it [was], ... it [was] pre-empted.”
Id.
at 306,
D. The Wellhead Decontrol Act
The NGPA did not end federal deregulation of natural gas. Many observers felt that the more modest price controls under the NGPA, like the stronger controls that preceded them, were having a damaging effect on the natural gas market. Judith M. Matlock,
The Natural Gas Wellhead Decontrol Act of 1989,
19 Colo. Law. 655, 655-56 (1990) (discussing criticisms of the post-NGPA price controls). In response to calls for further deregulation, Congress enacted the Natural Gas Wellhead Decontrol Act of 1989, Pub.L. No. 101-60, 103 Stat. 157 (the “WDA”). The WDA “completely eliminated FERC’s authority to set prices at the wellhead by removing ‘first sales’ from FERC’s rate-setting jurisdic
*864
tion.”
E. & J. Gallo Winery,
Finally, FERC itself took additional steps to further deregulate the natural gas transactions within its remaining jurisdiction in hopes of developing a more competitive market. In December of 1992, FERC effectively suspended the rate-filing requirements for all sales for resale within its jurisdiction by offering “blanket marketer certificates” for sales for resale other than sales to interstate pipelines (which themselves were already subject to blanket approval). Regulations Governing Blanket Marketer Sales Certificates, 57 Fed.Reg. 57,952, 57,957-58 (Dec. 8, 1992) (codified at 18 C.F.R. pt. 284);
see E. & J. Gallo Winery,
Historical Summary
In the early days of the natural gas industry, the Supreme Court recognized and enforced a rigid distinction between federal and state authority over the natural gas market, based primarily around the wholesale/retail distinction embodied in the Attleboro doctrine. In response, Congress enacted the NGA, which was designed to fill the “Attleboro gap” (the regulation of the interstate wholesale market) without interfering in states’ constitutionally permitted authority to regulate the retail and intrastate natural gas market. Because, however, the Attleboro doctrine itself fell quickly out of favor, the wholesale/retail distinction in the NGA became an issue of statutory rather than constitutional law. In Northern Natural, the Supreme Court held that the NGA established field preemption for interstate wholesales of natural gas. The NGPA deregulated first sales of much of the gas that had been subject to price controls under the NGA, but the Court held in Transcon that deregulation did not disturb the field pre-emption recognized in Northern Natural. Finally, the WDA deregulated the remaining regulated first sales, and subsequent FERC action eliminated rate-filing requirements for sales within its jurisdiction through blanket pre-approvals. Nevertheless, the Supreme Court has not suggested that either the WDA or the FERC deregulation has affected the import of the holding in Transcon.
IY. Analysis
The Plaintiffs do not contest that broad field pre-emption has been a cardinal feature of natural gas regulation for much of the previous century. Instead, they argue that under the current federal regime'— *865 and especially in light of the deregulatory steps taken in the WDA — their claims are not pre-empted because they arise, at least in part, out of transactions that are not within FERC jurisdiction. For the reasons set out below, we disagree.
As the United States Supreme Court has observed,
[mjaintaining the proper balance between federal and state authority in the regulation of ... energy utilities has long been a serious challenge to both judicial and congressional wisdom. On the one hand, the regulation of utilities is one of the most important of the functions traditionally associated with the police power of the Stаtes. On the other hand, the production and transmission of energy is an activity particularly likely to affect more than one State, and its effect on interstate commerce is often significant enough that uncontrolled regulation by the States can patently interfere with broader national interests.
Ark. Elec. Coop. Corp.,
When considering a claim that a Tennessee statute is subject to field preemption, we must first determine whether Congress intended to enact a system of field pre-emption, or if, in the alternative, Congress intended to limit state authority more narrowly — by pre-empting, for example, only those state regulations in actual conflict with the relevant federal law. If we conclude that field pre-emption exists, whatever the area of law, the second step in our analysis is to determine whether the Tennessee law intrudes upon that field. The Tennessee law survives only if it does not fall within the pre-empted field.
Schneidewind,
A. Field Pre-emption and its Scope under the WDA
There are no “precise guidelines” for determining whether or how broadly field pre-emption has occurred, because “each case turns on the peculiarities and special features of the federal regulatory scheme in question.”
City of Burbank v. Lockheed Air Terminal Inc.,
The Plaintiffs assert that, due to the enactment of the WDA, many of the wholesale natural gas transactions that were subject to FERC jurisdiction at the time of
Transom
and
Northern Natural
no longer are. This, they argue, demonstrates that Congress did not intend to exclude those transactions from state regulation. As the Supreme Court has noted, however, “a federal determination that deregulation was appropriate [is] entitled to as much weight in determining pre-emption as a federal decision to regulate actively.”
Transcon,
Nevertheless, the Plaintiffs are right to suggest that deregulation complicates our inquiry. Field pre-emption cases that involve statutes with a history of deregulation present unique challenges that more traditional field pre-emption cases do not. For example, courts typically look to whether Congress has enacted an “intricate web of statutory provisions
*866
[that] affords no room for the imposition of state-law” requirements.
French v. Pan Am Exp., Inc.,
That question is almost identical to the question that faced the Supreme Court in Transcon. In that case, the Court considered whether the pre-emption ruling in Northern Natural could be applied to gas that had been removed from FERC jurisdiction by the NGPA. In the case before us, we consider whether pre-emption continues to apply to gas that was removed from FERC jurisdiction by the WDA. If there is anything about the WDA that would dictate a different conclusion than that reached in Transcon regarding the NGPA, the Plaintiffs would prevail.
In our view, the Plaintiffs have not provided any persuasive reason to treat the pre-emptive effect of the two acts differently. Instead, they argue that this case is distinguishable from Transcon due to differences between the TTPA and the Transcon ratable taking requirement. We take that argument as relevant to the second step in our field pre-emption analysis — whether the Plaintiffs’ TTPA claims intrude on the field of pre-emption — but irrelevant to the question of whether the WDA, unlike the NGPA, reduced the preemptive force of the NGA.
When rejecting the argument that the NGPA reduced the pre-emptive effect of the NGA, the Court in Transcon made the following observation:
The aim of federal regulation remains to assure adequate supplies of natural gas at fair prices, but the NGPA reflects a congressional belief that a new system of natural gas pricing was needed to balance supply and demand. The new federal role is to “overse[e] a national market price regulatory scheme.” The NGPA therefore does not constitute a federal retreat from a comprehensive gas policy.
Furthermore, if indeed Congress intended by the WDA to reduce the amount of regulation of the natural gas market, it would make little sense to conclude that Congress simultaneously intended to expand states’ authority to regulate that same market. The last three decades of federal natural gas policy — from the NGPA to the more recent FERC orders— demonstrate a desire to lessen regulations in the natural gаs market; nothing, however, suggests a congressional aim to benefit the market by yielding to more intrusive legislation by the states. Moreover, “[r]e-peals by implication are not favored.”
Sullivan ex rel. Wrongful Death Beneficiaries of Sullivan v. Chattanooga Med. Investors, LP,
In our view, therefore, the field of preemption today is identical to the field recognized by the Supreme Court in pre-WDA cases: “the field of wholesale sales of natural gas in interstate commerce.”
Exxon Corp.,
B. Application to the TTPA Claims
Our next step is to consider whether enforcing the Plaintiffs’ claims under the TTPA would improperly intrude upon the federal field of pre-emption.

Two electrical power cases from the Ninth Circuit Court of Appeals,
Public Utility District No. 1 of Grays Harbor County Washington v. IDACORP Inc.,
Grays Harbor
and
Snohomish County
are, admittedly, distinguishable. First, of course, they consider electrical power, rather than natural gas, and thus are based on the FPA, not the NGA. The underlying principle, however — that price manipulation claims are pre-empted insofar as the field of price regulation is itself pre-empted — is equally applicable to natural gas under the NGA.
Cf.
DeVane, 14 Geo. Wash. L.Rev.
passim
(discussing shared history of the NGA and the FPA). Second, the market-based rates at issue in those cases were the result of deregulation by FERC, whereas some of the market-based rates in this case were the result of deregulation by statute.
Compare Grays Harbor,
Nevertheless, the Plaintiffs argue that the TTPA claims are not pre-empted because the TTPA is “complementary” to the NGA and its amending acts. The TTPA, they submit, is intended only to assure that goods are priced competitively, a goal consistent with the NGA, NGPA, and WDA. For that reason, they argue, there is no pre-emption. We disagree. Even if we were to assume that the TTPA claims would not be pre-empted if they were purely “complementary” to the federal regulatory regime, 9 our inquiry would not *869 end there, because an abstract preference for “competitive” pricing was not the only-goal of the federal enactments. Rather, the Plaintiffs’ argument would fail because it ignores two of the additional purposes of the federal statutory scheme: national uniformity and freedom from burdensome government intervention.
For decades, the Supreme Court has consistently identified uniformity as a central purpose of the NGA.
See Schneidewind,
Moreover, to hold that applying the TTPA would be complementary to the purposes of the NGA, NGPA, and WDA would ignore a key aim of the Congress in the passage of the latter two of those acts: the removal of restrictive regulations on the interstate market for natural gas wholesales. The common thread within the NGPA and the WDA — as well as subsequent FERC actions — is an overriding skepticism of government’s ability to intervene beneficially in the wholesale natural gas market. Whether Congress and FERC have gone too far is not for us to decide.
It is true that a goal of the TTPA is to assure that market forces function in a competitive manner — a purpose also attributable to NGPA and WDA deregula *870 tion, insofar (and only insofar) as Tennessee and federal law share the same view of what it means for a market to be competitive. Congress’s decision to deregulate, howеver, was not simply a decision to endorse some abstract ideal of “competitive” markets; rather, Congress made specific decisions about what it viewed as threats to competition, what tools were necessary to counter those threats, and which portions of the market did not require government intervention. Since the enactment of the NGA, the policy of Congress appears to be the result of careful deliberation and revision — a balance between regulation and deregulation that we are not free to disturb simply because we feel that our laws also promote competition within the market.
The stated purpose of the original Natural Gas Act price controls was to assure that the regulated prices were “just and reasonable.” NGA § 4(a). As Stephen Breyer and Paul W. MacAvoy have written, at the core of the concern that unregulated rates were not just and reasonable was the belief that natural gas producers had exercised monopolistic or oligopolistic “market power” permitting them “to raise the price of gas to the interstate pipelines
above the level that competition would otherwise dictate.”
Breyer & MacAvoy, 86 Harv. L.Rev. at 945 (emphasis added). As the Supreme Court observed in
Hope Natural Gas Co.,
“the investigations of the Federal Trade Commission had disclosed that the majority of the pipe-line mileage in the country used to transport natural gas, together with an increasing percentage of the natural gas supply for pipe-line transportation, had been
acquired by a handful of holding companies,”
and “[sjtate commissions, independent producers, and communities ... were growing quite helpless against
these combinations.”
The push to deregulate first sales was also the product of changing attitudes as to whether the natural gas market — specifically the natural gas market at the wellhead' — was competitive and what regulatory framework would best enable competition. “[Wjhile the question of market power played an important role in the early history of the debate over producer regulation, it ha[d] become less significant [by the early 1970s] as accumulated evidence ... created a strong presumption that gas producers d[id] not possess monopolistic or oligopolistic market power.” Breyer & MacAvoy, 86 Harv. L.Rev. at 945-46. This evidence guided Congress, in the enactment of the NGPA and the WDA, to deregulate first sales while retaining regulatory authority over other aspects of the market. Although the natural gas market has a multitude of participants — from producers to pipelines to utilities to consumers — the ultimate goal of the NGA was the “protection of
consumers
against exploitation at the hands of natural-gas companies.”
Phillips Petroleum Co.,
In short, the NGA, the NGPA, and the WDA were the result of Congress’s resolution of three core issues: first, what it means for a market to be competitive; second, whether the wholesale natural gas market, if free from regulation, would comply with that definition of “competitive”; and third, what the best mechanism was for correcting any flaws in that market. It is not, therefore, enough to say that both state and federal government are interested in “competition” and conclude that our laws are complementary. The relevant federal legislation reflects not just a broad commitment to competition, but specific policy answers to a number of difficult questions, such as when government intervention will be more damaging than nonintervention and which methods of intervention will be most effective without causing too much disruption. Because, as we have found, Congress enacted a broad regime of field pre-emption, we cannot substitute our judgment for that of Congress on those issues any more than we could substitute our judgment on the question of whether competition is desirable at all.
Our Court of Appeals based its holding on another Ninth Circuit case,
E. & J. Gallo Winery v. EnCana Corp.
In that case, the Ninth Circuit considered claims much like the claims here, explicitly rejecting a similar field pre-emption argument,
[t]he Supreme Court of the United States has appellate jurisdiction over federal questions arising either in state or federal proceedings, and by reason of the supremacy clause the decisions of that court on national law have binding effect on all lower courts whether state or federal. On the other hand, because lower federal courts exercise no appellate jurisdiction over state tribunals, decisions of lower federal courts are not conclusive on state courts.
United States ex rel. Lawrence v. Woods,
In that case, the Ninth Circuit dealt primarily with the filed rate doctrine, addressing only briefly the topic of field preemption and the holding in
Transcon. Compare
Finally, although the Plaintiffs have focused chiefly on the arguments that prevailed in
E. & J. Gallo Winery,
we will address an argument that they advanced both in the trial court and in our Court of Appeals; that is, that their claims are not pre-empted because they are based on consumer transactions, rather than sales for resale. We simply disagree. As indirect purchasers, they are ultimately challenging wholesale prices.

Conclusion
We conclude, therefоre, that the Plaintiffs’ claims under the TTPA have been pre-empted by federal law. 10 As a result, they have not stated a claim upon which relief can be granted. The chancery court properly dismissed their complaint. In reaching this conclusion, we are acutely aware that field pre-emption is a powerful tool by which the federal government may constrain the exercise of state authority, and that, therefore, courts must exercise the utmost caution before application of the doctrine. Nevertheless, our overriding duty is fealty to the decisions of the Supreme Court in an area of law that is undeniably federal in character. In Northern Natural, the Supreme Court set forth a broad field of pre-emption in natural gas cases. In Transcon, using logic that is no less applicable to the WDA, the Supreme Court ruled that field pre-emption continued to reach transactions that had been deregulated by the NGPA. Finally, in Schneidewind, the Supreme Court held that the field of pre-emption not only precluded direct price controls and ratable taking requirements, but extended to many regulations with an indirect bearing on prices. Although plausible arguments were made in each of these cases for a broader reading of state authority, we are bound to follow the path set out by the Supreme Court.
For that reason, the judgment of the Court of Appeals is reversed and costs are assessed to the Plaintiffs, for which execution may issue if necessary.
Notes
. Because this case was decided on a motion to dismiss, the following facts were taken from the pleadings.
. Rеporting firms have divided the natural gas market — often by region — into various "trading desks,” to reflect variation among different segments of the national market.
. Reliant Energy Services, Inc. and Reliant Energy, Inc. have apparently changed their corporate names since this litigation began. For the sake of convenience, we use the old names.
. The Plaintiffs have since revised their field pre-emption argument to mirror the rationale adopted by the Court of Appeals.
. All arrangements, contracts, agreements, trusts, or combinations between persons or corporations made with a view to lessen, or which tend to lessen, full and free competition in the importation or sale of articles imported into this state, or in the manufacture or sale of articles of domestic growth or of domestic raw material, and all arrangements, contracts, agreements, trusts, or combinations between persons or corporations designed, or which tend, to advance, reduce, or control the price or the cost to the producer or the consumer of any such product or article, are declared to be against public policy, unlawful, and void.
Tenn.Code Ann. § 47-25-101.
Any arrangements, contracts, and agreements that may be made by any corporation or person, or by and between its agents and subagents, to sell and market its products and articles, manufactured in this state, or imported into this state, to any producer or consumer at prices reduced below the cost of production or importation into this state, including thе cost of marketing, and a reasonable and just marginal profit, to cover wages or management, and necessary incidentals, as is observed in the usual course of general business, and the continuance of such practice under such contracts and arrangements for an unreasonable length of time, to the injury of full and free competition, or any other arrangements, contracts, or agreements, by and between its agents and subagents, which tend to lessen full and free competition in the sale of all such articles manufactured and imported into the state, and which amount to a subterfuge for the purpose of obtaining the same advantage and purposes are declared to be against public policy, unlawful, and void.
Tenn.Code Ann. § 47-25-102.
. The Commerce Clause provides that Congress shall have the power "[tjo regulate Commerce with foreign Nations, and among the several States, and with the Indian tribes.” U.S. Const, art. I, § 8, cl. 3. Although the clause is primarily a grant of authority to Congress, courts have long recognized that it also imposes restrictions on the authority of states through what has been called the "dormant Commerce Clause doctrine.”

DeVane, 14 Geo. Wash. L.Rev. at 32. Investment in the pipeline facilities numbered in the billions of dollars. Id.
. As an initial matter, the Plaintiffs go to great lengths to distinguish their TTPA claims from the ratable taking requirements at issue in Northern Natural and Transcon. As we have discussed, however, Northern Natural and Transcon do not define the outer bounds of natural gas field pre-emption. The securities regulation struck down in Schneidewind was significantly more attenuated from the core concerns of the NGA than the ratable taking requirements, and the Supreme Court still found pre-emption. Whether the TTPA claims can be distinguished from a ratable taking requirement is, therefore, not determinative.
. To the contrary, however, it is highly questionable that complementarity can ever be a defense against Held pre-emption.
See Locke,
. Because we decide this case on the question of field pre-emption, we have not considered the parties’ filed rate doctrine arguments. We also decline to reconsider Tennessee's pleading standards, as some of the Defendants have urged.
