OPINION 

¶ 1 The United States Court of Appeals for the Seventh Circuit has certified for instruction 

from this court the following question of Illinois law: Does the Illinois Commerce Commission 

have exclusive jurisdiction over a reparation claim, as defined in Sheffler v. Commonwealth 

Edison Co., 2011 IL 110166, brought by a residential consumer against an alternative retail 

electric supplier, as defined by section 16-102 of the Electric Service Customer Choice and 

Rate Relief Law of 1997 (220 ILCS 5/16-102 (West 2014))? Zahn v. North American Power & 

Gas, LLC, 815 F.3d 1082, 1095 (7th Cir. 2016). We accepted the Seventh Circuit’s invitation 

to consider this question pursuant to Illinois Supreme Court Rule 20 (eff. Aug. 1, 1992).1

 For 

the reasons that follow, we answer the question in the negative. Under Illinois law, the Illinois 

Commerce Commission does not have exclusive original jurisdiction over such claims. The 

claims may be pursued through the courts. 

¶ 2 BACKGROUND 

¶ 3 We take the facts as the Seventh Circuit has stated them in its certification ruling. They are 

simple and straightforward. Peggy Zahn is a residential consumer of electric power. North 

American Power & Gas, LLC (NAPG), is an alternative retail electric supplier (ARES) within 

the meaning of section 16-102 of the Electric Service Customer Choice and Rate Relief Law of 

 

1

In the proceedings before our court, the Illinois Commerce Commission sought and was granted 

leave to file a friend of the court brief pursuant to Illinois Supreme Court Rule 345 (eff. Sept. 20, 2010) 

in support of Peggy Zahn, plaintiff in the federal action. The Illinois Competitive Energy Association, 

in turn, requested permission to file a friend of the court brief supporting North American Power & Gas, 

LLC, the defendant in the federal action. Its request was also allowed. In addition, we allowed the State 

of Illinois to intervene. As with the Commerce Commission, the State supports Zahn’s position.

1997 (Rate Relief Law) (220 ILCS 5/16-102 (West 2014)), which is part of the Public Utilities 

Act (Act) (220 ILCS 5/1-101 (West 2014)). 

¶ 4 As defined by section 16-102, an ARES is any “person, cooperative, corporation, 

municipal corporation, company, association, joint stock company or association, firm, 

partnership, individual, or other entity, their lessees, trustees, or receivers appointed by any 

court whatsoever, that offers electric power or energy for sale, lease or in exchange for other 

value received to one or more retail customers, or that engages in the delivery or furnishing of 

electric power or energy to such retail customers, and shall include, without limitation, 

resellers, aggregators and power marketers,” subject to various exceptions. 220 ILCS 5/16-102 

(West 2014). ARESs were authorized by the General Assembly when it enacted the Rate 

Relief Law as part of an effort to partially deregulate our state’s electricity market and make it 

more competitive. Under this new system, consumers are no longer confined to purchasing 

their power from their local public utility. Rather, they have the option of buying their power 

from the local public utility, an electric utility other than their local public utility, or an ARES. 

Zahn, 815 F.3d at 1084-85. 

¶ 5 In August 2012, Zahn decided to purchase her electricity from NAPG based on its promise 

of lower rates. NAPG sent Zahn a letter stating that she would receive its “New Customer 

Rate” of $0.0499 per kilowatt-hour during her first month of service and a “market based 

variable rate” thereafter. The company also sent her its “Electricity Sales Agreement Customer 

Disclosure Statement.” The statement indicated that the term of the agreement was 

month-to-month and that “[o]ther than fixed and/or introductory/promotional rates, all rates 

shall be calculated in response to market pricing, transportation, profit and other market price 

factors.” It also disclosed, under the heading “Open Price,” that its prices were “variable” 

based on “market prices for commodity, transportation, balancing fees, storage charges, 

[NAPG] fees, profit, [and] line losses ***. Your price may be higher or lower than your [local 

public utility] ***.” 

¶ 6 Zahn never received the $0.0499 per kilowatt-hour “New Customer Rate” she was 

promised. During her first two months of service, September and October 2012, NAPG 

charged her $0.0599 per kilowatt-hour. Thereafter, from November 2012 through June 2014, 

the rate it charged her was always higher than what she would have been required to pay her 

local public utility, Commonwealth Edison (ComEd), had she not switched to NAPG. At 

times, NAPG’s rate was nearly triple ComEd’s.

¶ 7 Zahn objected to NAPG’s higher charges and filed a class action against the company in 

the United States District Court for the Northern District of Illinois. Zahn’s complaint invoked 

the court’s diversity jurisdiction (28 U.S.C. § 1332 (2012)) and sought damages based on 

violation of the Consumer Fraud and Deceptive Business Practices Act (815 ILCS 505/1 

et seq. (West 2014)), common-law breach of contract, and unjust enrichment. NAPG moved to 

dismiss Zahn’s complaint for lack of subject-matter jurisdiction and failure to state a claim. 

The district court granted that motion. Zahn then appealed to the United States Court of 

Appeals for the Seventh Circuit. It is in that appeal that the question before us was certified. 

¶ 8 In assessing whether the district court erred in dismissing Zahn’s complaint, the Seventh 

Circuit has concluded that the dispositive threshold issue is whether an Illinois state court 

would have had subject-matter jurisdiction to hear plaintiff’s claims or whether exclusive 

jurisdiction over those claims lies, instead, with the Illinois Commerce Commission. The 
- 4 - 

Seventh Circuit reasoned that if the Commerce Commission alone has jurisdiction to hear 

claims of this kind under Illinois law and such claims are not within the subject-matter 

jurisdiction of the Illinois state courts, it necessarily follows that a federal district court sitting 

in diversity cannot entertain them either. Zahn, 815 F.3d at 1087 (citing Tacket v. General 

Motors Corp., Delco Remy Division, 93 F.3d 332, 334 (7th Cir. 1996)). 

¶ 9 In Sheffler v. Commonwealth Edison Co., 2011 IL 110166, this court addressed the lines of 

demarcation between the jurisdiction of the Illinois Commerce Commission and the 

jurisdiction of the courts with respect to claims against public utilities. Citing section 9-252 of 

the Public Utilities Act (220 ILCS 5/9-252 (West 2014)), which pertains to complaints 

“concerning any rate or other charge of any public utility,” and in accordance with precedent 

from our appellate court, we held there that if a claim is deemed to be one for “reparations” 

rather than for civil damages, jurisdiction lies with the Commerce Commission, not the courts. 

A reparations claim is one where the essence of the grievance is that a public utility has 

charged too much for a service. A civil damages claim, by contrast, is one where the gist of the 

complaint is that a public utility has done something else to wrong the plaintiff. Sheffler, 2011 

IL 110166, ¶¶ 41-42. 

¶ 10 In the case before us, the Seventh Circuit has characterized Zahn’s claims as being in the 

nature of “reparations” as that term is used in Sheffler. There is an important difference, 

however, between this case and Sheffler. Sheffler involved a claim against a conventional 

public utility. The claim asserted here is against an ARES. Under section 3-105(b)(9) of the 

Public Utilities Act (220 ILCS 5/3-105(b)(9) (West 2014)), ARESs are expressly excluded 

from the definition of public utility. Pursuant to section 16-102 of the Rate Relief Law (220 

ILCS 5/16-102 (West 2014)), ARESs do not qualify as “electric utilities” either. They are 

merely “nonutilities licensed to sell retail electricity.” Commonwealth Edison Co. v. Illinois 

Commerce Comm’n, 328 Ill. App. 3d 937, 939 (2002). 

¶ 11 Because NAPG is an ARES and ARESs are not utilities, the Seventh Circuit recognized 

that Sheffler does not resolve the question of whether claims against NAPG by customers 

seeking reparations for overbilling may only be brought before the Commerce Commission. 

Finding no other decision by this court directly on point, the Seventh Circuit looked to the 

legislature’s stated and implied intent, the Rate Relief Law’s consumer protection provisions 

and remedial measures, an unpublished order by our appellate court, an interim order by the 

Commerce Commission in an unrelated case, and a published decision by the appellate court 

involving a reparations claim against a telecommunications carrier in an attempt to estimate 

how we would decide the question if it came before us. The Seventh Circuit ultimately 

concluded that these sources failed to yield a definitive answer. It has therefore reached out to 

us directly here, through the mechanism of a certified question, for instruction. 

¶ 12 ANALYSIS 

¶ 13 As set forth above, the viability of Zahn’s state law claims against NAPG in her federal 

diversity action turns on whether an Illinois state court would have had subject-matter 

jurisdiction to hear them or whether, under Illinois law, she would have been limited to 

pursuing those claims in an administrative proceeding before the Commerce Commission. The 

general principles governing this inquiry were recently discussed by our court in J&J Ventures 

Gaming, LLC v. Wild, Inc., 2016 IL 119870. As we noted there, subject-matter jurisdiction 
- 5 - 

refers to a tribunal’s power to hear and determine cases of the general class to which the 

proceeding in question belongs. Id. ¶ 23. The Illinois Constitution vests the circuit courts with 

original jurisdiction of all “justiciable matters” except when our court possesses “original and 

exclusive jurisdiction relating to redistricting of the General Assembly and to the ability of the 

Governor to serve or resume office.” Ill. Const. 1970, art. VI, § 9. Accordingly, so long as a 

matter brought before a circuit court is justiciable and does not fall within the original and 

exclusive jurisdiction of our court, a circuit court has subject-matter jurisdiction to consider it. 

McCormick v. Robertson, 2015 IL 118230, ¶ 20. 

¶ 14 In this case, there is no issue as to justiciability, and the matter is not one that falls within 

this court’s original and exclusive jurisdiction. The only reason there is any doubt as to 

whether an Illinois circuit court would have jurisdiction to consider plaintiff’s claims is that 

there is a line of Illinois authority holding that our General Assembly may vest original 

jurisdiction in an administrative agency rather than the courts when it enacts a comprehensive 

statutory scheme that creates rights and duties that have no counterpart in common law or 

equity. J&J Ventures Gaming, LLC, 2016 IL 119870, ¶ 23.2 Even if one puts aside the 

question of whether the claims asserted by Zahn in this case can properly be said to involve 

rights or duties unknown in common law or equity, we do not believe that exception is 

applicable. 

¶ 15 If the legislature intends for exclusive original jurisdiction to lie with the agency rather 

than with the circuit courts when it has enacted such a comprehensive statutory scheme, it must 

make that intention explicit. Id. ¶¶ 23-24. It has not done so here. While section 9-252 of the 

Public Utilities Act (220 ILCS 5/9-252 (West 2014)) does give the Commerce Commission 

exclusive original jurisdiction over claims that a public utility has charged “an excessive or 

unjustly discriminatory amount for its product, commodity or service,” ARESs are not public 

utilities. In defining public utilities, the Act expressly excludes them. See 220 ILCS 

5/3-105(a)(9) (West 2014). The claims asserted by plaintiff in this case therefore do not fall 

within the Commerce Commission’s exclusive jurisdiction under section 9-252 of the Act. To 

hold otherwise would require us to interpret the statute in a way that is directly contrary to its 

express terms. That, of course, is something we may not do. No rule of construction authorizes 

us to declare that the legislature did not mean what the plain language of the statute imports, 

nor may we rewrite a statute to add provisions or limitations the legislature did not include. 

Illinois State Treasurer v. Illinois Workers’ Compensation Comm’n, 2015 IL 117418, ¶ 28. 

¶ 16 NAPG argues that section 9-252 alone is not dispositive and that, in assessing the 

legislature’s intentions regarding the Commerce Commission’s jurisdiction, we should 

consider the overall statutory framework. There is support for this approach in J&J Ventures 

Gaming, LLC, 2016 IL 119870, where we recently held that legislative intent to divest circuit 

courts of jurisdiction and to place exclusive original jurisdiction in an administrative agency 

may be discerned by considering the statute as a whole, with the relevant provisions construed 

together and not in isolation and with an eye toward the reason for the law, the problems sought 

to be remedied, and the purposes to be achieved. Id. ¶¶ 24-25. Application of that approach, 

 

2Although our precedent refers to the “jurisdiction” of administrative agencies, that is something of 

a misnomer. The term “jurisdiction” is not strictly applicable when referring to an administrative 

agency. We use it as shorthand for describing the agency’s authority to act. J&J Ventures Gaming, 

LLC, 2016 IL 119870, ¶ 23 n.6. 
- 6 - 

however, does not support NAPG’s assertion that the legislature intended for the Commerce 

Commission to have exclusive jurisdiction over claims such as plaintiff asserted against 

ARESs. 

¶ 17 The Rate Relief Law, which created ARESs, is a component of the Public Utilities Act 

(220 ILCS 5/1-101 et seq. (West 2014)), and it is the Public Utilities Act that provides the 

foundational statutory scheme at play in this case. The Public Utilities Act was enacted to 

assure the provision of efficient and adequate utility service to the public at a reasonable cost. 

Local 777 v. Illinois Commerce Comm’n, 45 Ill. 2d 527, 535 (1970). The Commerce 

Commission was created under the Act as the body responsible for maintaining “a balance 

between the rates charged by utilities and the services performed.” Sheffler v. Commonwealth 

Edison Co., 2011 IL 110166, ¶ 40. 

¶ 18 The rate-making process is a complicated one. See, e.g., Ameren Illinois Co. v. Illinois 

Commerce Comm’n, 2012 IL App (4th) 100962, ¶¶ 8-13 (describing how the Commerce 

Commission establishes the rates a public utility may charge its customers). The legislature’s 

decision to place responsibility for that process on the Commerce Commission is a reflection 

of that complexity. In creating the Commerce Commission, the legislature understood that 

insuring that a public utility’s rates are just and reasonable and that its services are adequate 

would require consideration of complex technological and scientific data and expert opinion, 

and it determined that such matters are best addressed by a tribunal that is itself capable of 

passing upon complex data. See Sheffler, 2011 IL 110166, ¶ 40. 

¶ 19 When the legislature established the regulatory structure for public utilities under the 

Public Utilities Act and then conferred on the Commerce Commission responsibility for 

determining whether rates charged by those utilities are just and reasonable, it also vested 

exclusive jurisdiction in the Commerce Commission to consider complaints that a utility has 

charged an amount for its product, commodity, or service that is excessive or unjust. Id. ¶ 41; 

220 ILCS 5/9-252 (West 2014). This is entirely logical. If technical expertise is needed to 

determine whether a utility rate is just and reasonable, it follows that the same technical 

expertise may be necessary to ascertain whether the rate subsequently charged by the utility is 

unjust or excessive. The two go hand in hand. 

¶ 20 Such considerations are not present, however, when it comes to ARESs. ARESs were not 

part of the traditional regulatory system established to govern public utilities. They were 

introduced under the Rate Relief Law as part of an effort to partially deregulate Illinois’s 

electricity market (Zahn, 815 F.3d at 1084-85). As we have already pointed out, ARESs are 

expressly excluded from the definition of “public utility” under the Public Utilities Act (220 

ILCS 5/3-105(b)(9) (West 2014)) and are not “electric utilities” under section 16-102 of the 

Rate Relief Law (220 ILCS 5/16-102 (West 2014)). They are simply “nonutilities licensed to 

sell retail electricity” (Commonwealth Edison Co. v. Illinois Commerce Comm’n, 328 Ill. App. 

3d 937, 939 (2002)). As such—and there is no dispute on this point—the prices they are 

permitted to charge are not established by the Commerce Commission through the 

conventional rate-making process and do not have to be submitted to the Commerce 

Commission for approval under the “just and reasonable” standard. In contrast to public 

utilities, an ARES’s prices are a matter of contract between the ARES and its customers. The 

technical and regulatory expertise of the Commerce Commission does not come into play. 

Accordingly, the justification for giving the Commerce Commission exclusive original 
- 7 - 

jurisdiction over the disputes involving rates charged by public utilities is absent where, as 

here, the complaint concerns overcharging by an ARES. 

¶ 21 NAPG correctly points out that ARESs are subject to numerous statutory requirements that 

are under authority of the Commerce Commission. For example, there are provisions 

obligating ARESs to obtain certificates of service authority from the Commerce Commission 

before serving residential customers (220 ILCS 5/16-115(a) (West 2014)); that forbid ARESs 

from discriminating against customers based on race, gender, or income (220 ILCS 

5/16-115A(d) (West 2014)); that require them to obtain authorization in prescribed form 

before switching customers from another supplier (220 ILCS 5/16-115A(b) (West 2014)); and 

that impose standards regarding their marketing and billing practices (220 ILCS 5/16-115A(e) 

(West 2014)). Under section 16-115B(a) of the Rate Relief Law (220 ILCS 5/16-115B(a) 

(West 2014)), complaints alleging violation or nonconformance with these or other provisions 

of the law applicable to ARESs may be entertained by the Commerce Commission. If the 

Commerce Commission determines that an ARES is in violation or nonconformance, it may 

order the ARES to cease and desist; impose financial penalties; or alter, modify, revoke, or 

suspend the ARES’s certificate of service authority. 220 ILCS 5/16-115B(b) (West 2014). 

¶ 22 Zahn, the State, and the Commerce Commission differ somewhat in their assessment of the 

significance of these additional provisions. In the State’s view, they should be read as 

permitting claims such as those asserted by Zahn to be heard and disposed of by the Commerce 

Commission if an aggrieved residential consumer elects to pursue them in that forum. The 

Commerce Commission itself suggests that, at the most, its jurisdiction extends only to claims 

that an ARES’s rates or services are impermissible because they contravene the particular 

factors set forth in section 16-115A(d) of the Rate Relief Law (220 ILCS 5/16-115A(d) (West 

2014)), a situation not present here. As for Zahn, she asserts that notwithstanding whatever 

other authority the Commerce Commission may possess, the absence of a provision expressly 

authorizing it to order reparations to consumers precludes a construction of the law that would 

confer exclusive jurisdiction over such claims on the Commerce Commission. 

¶ 23 We express no view on the relative merits of these respective positions, for it is 

unnecessary for us to do so. Whatever the precise scope of the Commerce Commission’s 

authority to consider claims asserted by residential consumers against ARESs, it is clear that 

nothing in the additional sections of the Public Utilities Act, including the provisions of the 

Rate Relief Law cited by NAPG, can fairly be read as expressing an explicit intention by the 

legislature that the Commerce Commission has exclusive original jurisdiction over those 

claims. Where the General Assembly has intended to confer exclusive jurisdiction on the 

Commerce Commission regarding a particular issue, it has said so specifically. See, e.g., 220 

ILCS 5/16-125(h) (West 2014) (“[r]emedies provided for under this Section [governing 

transmission and distribution reliability] may be sought exclusively through the Illinois 

Commerce Commission as provided under Section 10-109 of [the Public Utilities] Act”). 

NAPG can cite no similar language with respect to claims of overcharging asserted by 

residential consumers against ARESs. Consideration of the statute as a whole, as well as the 

reason for the law, the problems sought to be remedied, and the purposes to be achieved, 

therefore reaffirms the conclusion we reached at the outset of this opinion based on our 

examination of section 9-252 of the Public Utilities Act: the claims of the type asserted by 

plaintiff in this case do not fall within the Commerce Commission’s exclusive jurisdiction. 
- 8 - 

That being so, an Illinois circuit court would have subject-matter jurisdiction to entertain them. 

¶ 24 CONCLUSION 

¶ 25 For the foregoing reasons, we answer the certified question “Does the Illinois Commerce 

Commission have exclusive jurisdiction over a reparation claim, as defined in Sheffler v. 

Commonwealth Edison Company, 2011 IL 110166, brought by a residential consumer against 

an alternative retail electric supplier, as defined by section 220 ILCS 5/16–102?” in the 

negative. 

¶ 26 Certified question answered.
