delivered the opinion of the court:
Plaintiff, Josephine Kirwin, appeals the circuit court of Cook County’s dismissal of her amended complaint against defendants, Peoples Gas Light and Coke Company (Peoples Gas) and the City of Chicago (the city). The gravamen of her complaint is that the city has not enforced, and that Peoples Gas is out of compliance with, an ordinance mandating the testing of every gas meter in the city every seven years. The circuit court granted the Illinois Commerce Commission (ICC) leave to intervene as a party defendant. The court based its dismissal of the action on Peoples Gas Light & Coke Co. v. City of Chicago (1984), 125 Ill. App. 3d 95, 465 N.E.2d 603, which held an ordinance prohibiting Peoples Gas from terminating gas service to residential customers between the months of November and March invalid as beyond its home rule powers. The appellate court concluded that the State legislature and courts had vested exclusive regulatory jurisdiction over public utilities in the ICC.
On appeal, plaintiff contends generally that the State has not preempted the city’s police power to regulate gas meters within its boundaries.
The subject ordinance provides that “[n]o meter after having been once tested and sealed as herein provided shall be allowed to remain in service longer than seven years before being again tested and sealed, as herein provided.” Chapter 187 of the Municipal Code further provides that such testing is to be done by the city inspector of weights and measures. Chicago Municipal Code §§187 — 12, 187 — 8
(1983) .
On the other hand, ICC general Order No. 159, entitled “Standards of Service for Gas Utilities” (83 Ill. Adm. Code 500.10 et seq. (1984) ), promulgated in accordance with the provisions of section 54 of “An Act concerning public utilities” (Ill. Rev. Stat. 1981, ch. 1112/3, par. 1 et seq.) (the Utilities Act), establishes certain State standards for gas service. (83 Ill. Adm. Code 500.10 (1984).) In contrast to the Chicago Municipal Code, the order contemplates that the testing of gas meters shall be done by the public utilities themselves. (See, e.g., 83 Ill. Adm. Code 500.180, 500.200, 500.215 (1984).) It further provides that “[n]o meter shall be allowed to remain in service more than ten years from the time last tested without being retested.” (83 Ill. Adm. Code 500.210 (1984).) Finally, the order allows utilities to adopt scientific sample testing of new and in-service meters and sets certain *703requirements for such testing. 83 Ill Adm. Code 500.215 (1984).
The validity of the subject ordinance turns on whether it constitutes the exercise or performance of a power or function pertaining to the city’s government and affairs as provided for in article VII, section 6, of the Illinois Constitution of 1970. (See County of Cook v. John Sexton Contractors Co. (1979), 75 Ill. 2d 494, 508, 389 N.E.2d 553; Peoples Gas Light & Coke Co. v. City of Chicago (1984), 125 Ill. App. 3d 95, 98, 465 N.E.2d 605.) That section of the Illinois Constitution provides, inter alia:
“(a) *** Except as limited by this Section, a home rule unit may exercise any power and perform any function pertaining to its government and affairs including, but not limited to, the power to regulate for the protection of the public health, safety, morals and welfare; ***
* * *
(m) Powers and functions of home rule units shall be construed liberally.” (Ill. Const. 1970, art. VII, §6.)
The terms of the grant of home rule power are broad and imprecise, leaving to the courts the duty to determine whether a power exercised by a home rule unit is within the grant of section 6(a). Ampersand, Inc. v. Finley (1975), 61 Ill. 2d 537, 539-40, 338 N.E.2d 15; County of Cook v. John Sexton Contractors Co. (1979), 75 Ill. 2d 494, 508, 389 N.E.2d 553.
If the legislature specifically denies or limits any power or function of a home rule unit in accordance with paragraphs (g), (h), (i), (j), or (k) of section 6 of article 7 of the Constitution (Ill. Const. 1970, art. VII, §§6(g), (h), (i), (j), (k)), and section 7 of “An Act to revise the law in relation to the construction of the statutes” (Ill. Rev. Stat. 1981, ch. 1, par. 1106), no difficulty arises in resolving the issue. (Hutchcraft Van Service, Inc. v. City of Urbana Human Relations Comm’n (1982), 104 Ill. App. 3d 817, 822, 433 N.E.2d 329.) Where a statute does not contain such specific provisions, however, the courts must determine whether the legislature intended to preempt the area which is the subject of the statute involved. (Hutchcraft Van Service, Inc., 104 Ill. App. 3d at 823.) In the context of State action versus local action, preemption means the end of local legislative control over a given subject where the legislature has adopted a scheme of regulation over the same subject. Hutchcraft Van Service, Inc., 104 Ill. App. 3d 817.
With respect to the Utilities Act we must acknowledge that the legislature has not specifically denied or limited home rule powers over the regulation of public utilities since 1970. The legislature’s fail*704ure to act notwithstanding, we believe it is beyond peradventure that the regulation of public utilities generally, and of public gas utilities’ meters specifically, have been, since 1913, matters of statewide, not local, concern.
Section 1 of the original Utilities Act created a State Public Utilities Commission. (Ill. Rev. Stat. 1913, ch. 111a, par. 1 (Hurd).) Section 8 of the Act provided, inter alia:
“The commission shall have general supervision of all public utilities, shall inquire into the management of the business thereof and shall keep itself informed as to the manner and method in which the business is conducted. It shall examine such public utilities and keep informed as to *** the manner in which their plants, equipments and other property *** are managed, conducted and operated, not only with respect to the adequacy, security and accommodation afforded by their service but also with respect to their compliance with' the provisions of this act and any other law, with the orders of the commission ***.” (Ill. Rev. Stat. 1913, ch. 111a, par. 8 (Hurd).)
Section 9 of the original Utilities Act provided, inter alia:
“Every public utility shall obey and comply with each and every requirement of every order, decision, direction, rule or regulation made or prescribed by the commission ***.” (Ill. Rev. Stat. 1913, ch. 111a, par. 9 (Hurd).)
Finally, section 54 of the Act provided:
“The commission shall have power *** to ascertain, determine and fix adequate and serviceable standards for the measurement of quantity, *** or other condition pertaining to the performing of its service or to the furnishing of its product or commodity by any public utility, and to prescribe reasonable regulations for examining, measuring, and testing such service, product or commodity, and to establish reasonable rules, regulations, specifications and standards to secure the accuracy of all meters and appliances for examining, measuring, or testing such service, product or commodity. ***
The commission shall provide for the inspection of the manner in which every public utility conforms to the reasonable regulations prescribed by the commission for examining, measuring and testing its service, product or commodity, and the commission may supplement such inspections by examining, measuring, and testing the service, product or commodity of any public utility.” (Emphasis added.) Ill. Rev. Stat. 1913, ch. 111a, par. 54 (Hurd).
*705Thus, plaintiff is clearly in error when she asserts that nothing in the original act “in any way appears to relate to the testing of gas meters.” Rather, the original Utilities Act created a comprehensive scheme for the regulation of public utilities generally, and the testing of gas utilities’ meters specifically, by the State.
Moreover, sections 8, 9 and 54 were not changed in the 1921 version of the Public Utilities Act (Ill. Rev. Stat. 1921, ch. 1112/3, pars. 8, 9, 54), which also replaced the State Public Utilities Commission with the Illinois Commerce Commission and repealed the 1913 Act (Ill. Rev. Stat. 1921, ch. lilacs, pars. 1, 91). Finally, these sections of the earlier Utilities Act continue, as quoted, in the present Utilities Act. See Ill. Rev. Stat. 1985, ch. 1112/3, pars. 4— 101, 5-101, 8-301.
This review of the Utilities Act reveals that the regulation of public utilities generally and of gas utilities’ meters specifically have been, since 1913, areas of statewide, not local, concern and that the Utilities Act has preempted the city’s authority on those subjects. Because the regulation of gas meters has not been an area pertaining to the government and affairs of the city since 1913, the city did not have home rule powers with respect thereto which were in the contemplation of section 6(a) of article 7 of the 1970 Illinois Constitution.
We must acknowledge the rule that it is manifestly impossible to find a legislative intent to limit a city’s home rule powers in statutes predating the 1970 Constitution because the concept of home rule was totally foreign to pre-1970 legislative contemplation. (Kanellos v. County of Cook (1972), 53 Ill. 2d 161, 166-67, 290 N.E.2d 240; City of Rockford v. Gill (1979), 75 Ill. 2d 334, 341, 388 N.E.2d 384.) However, the issue here is not whether the legislature, in enacting and reenacting the Utilities Act since 1913, thereby “limited” Illinois municipalities’ home rule powers over public utilities. Rather, we believe it is whether the legislature thereby “preempted” whatever authority over public utilities Illinois municipalities may have possessed prior to 1913.
Prior to 1970, including the period before 1913, all Illinois municipalities possessed only those powers which they were expressly granted by the legislature or which were necessarily implied in or incidental to powers expressly granted. (Ives v. City of Chicago (1964), 30 Ill. 2d 582, 584, 198 N.E.2d 518, 1 J. Dillon, Municipal Corporations 448-50 (5th ed. 1911) (This principle was commonly referred to as Dillon’s Rule).) The legislature could modify, restrict, or entirely withdraw these powers at will. (City of Geneseo v. Illinois *706 Northern Utilities Co. (1936), 363 Ill. 89, 93, 1 N.E.2d 392.) One method by which the State could withdraw these powers was to establish “new administrative bodies and confer upon them some, or all, of the powers and rights which were formerly prerogatives of [a] *** municipality.” City ofGeneseo, 363 Ill. at 93.
Viewing the issue as the “preemption” of powers expressly granted the city by the legislature before 1913 sufficiently answers plaintiff’s reliance on the city’s asserted power, prior to 1913, to regulate gas meters. She notes that the city’s amended charter of 1863 conferred upon it the power to seal and inspect weights and measures used for sales by measure or weight and that the city has purported by ordinance to require the testing of all new or in-service gas meters since 1907. Even assuming that the former versions of the subject ordinance were validly enacted pursuant to the city’s charter, the enactment of the Public Utilities Act in 1913 divested the city of all power to regulate gas meters, as will be made clear below.
According to Professor David C. Baum, who served as counsel to the committee on local government of the Sixth Illinois Constitutional Convention, the framers of the 1970 Illinois Constitution “specifically frowned upon” a judicial preemption doctrine based on preexisting legislative regulation to limit home rule powers. (Baum, A Tentative Survey of Illinois Home Rule: Powers & Limitations (pt. 1), 1972 U. Ill. L.F. 137, 156.) Notwithstanding that fact and that “preexisting statutes should not operate to restrain home rule units in the exercise of their powers” (Baum, A Tentative Survey of Illinois Home Rule: Powers & Limitations (pt. 2), 1972 U. Ill. L.F. 559, 579), however, Professor Baum also stated:
“We should acknowledge, perhaps, one set of exceptions to this conclusion. As noted earlier, extensive state *** regulation of a field of governmental activity may stamp that field as statewide *** in nature. This characterization would remove that field from those subjects that 'pertain’ to the government and affairs of home rule units and thus also remove it from the powers granted to home rule units by section 6(a). This argument is peculiarly suited to solving problems raised by the transition to home rule. The General Assembly may well neglect to reenact some important preexisting legislation. I have already suggested the examples of statutes placing utility regulation and some aspects of pollution control in the hands of state administrative agencies. This omission should not necessarily permit home rule units to invade these two vi*707tal areas of state concern. A court could rule that those aspects of utility regulation and pollution control that are delegated by statute to the state agencies simply are of statewide rather than local concern and fall outside of the legislative competence of home rule units.” (Baum, A Tentative Survey of Illinois Home Rule: Powers & Limitations (pt. 2), 1972 U. Ill. L.F. 559, 579.)
Supportive of Professor Baum’s conclusions is an observation of the local government committee in its report containing its proposed local government article. In discussing sections 3.2(a) and (b) thereof, now sections (6Xg) and (h) of article VII, the committee observed, aptly to the issue before us, that “extensive conflict could result if each home rule unit *** could regulate public utilities independently and the state was powerless to vest exclusive jurisdiction in a utilities commission.” 7 Record of Proceedings, Sixth Illinois Constitutional Convention 1642.
In view of the State’s strong and pervasive interest in uniform public utility regulation (Peoples Gas Light & Coke Co. v. City of Chicago (1984), 125 Ill. App. 3d 95, 98, 465 N.E.2d 603) manifested by the Utilities Act, we believe the city’s attempt to regulate the testing of Peoples Gas’ meters would do immediate and serious harm to an important State interest. As such, we must conclude that the Utilities Act has preempted this area. See Baum, A Tentative Survey of Illinois Home Rule: Powers and Limitations (pt. 2), 1972 U. Ill. L.F. at 579.
Plaintiff cites City of Geneseo v. Illinois Northern Utilities Co. (1941), 378 Ill. 506, 39 N.E.2d 26, cert. denied (1942), 316 U.S. 670, 86 L. Ed. 1746, 62 S. Ct. 1046 (City of Geneseo II), as recognizing that municipalities may exercise police powers not involving distinctive public utility features or uses as long as such exercise does not defeat the objectives of the Utilities Act. City of Geneseo involved an attempt to remove the defendants’ equipment from the plaintiff cities’ streets after expiration of the defendants’ franchises to operate within the cities. The ICC had dismissed the complaints based on a prior decision of the supreme court in the same case holding that the Utilities Act had divested municipalities of the power to regulate public utilities. (City of Geneseo v. Illinois Northern Utilities Co. (1936), 363 Ill. 89, 1 N.E.2d 392.) After concluding that its prior decision was not res judicata as to the appeal before it, the court noted that the Utilities Act had not expressly given the ICC power to control the streets of municipalities. As such, the court reversed the ICG’s dismissals of the plaintiff cities’ complaints.
*708 City of Geneseo, in fact, supports the conclusion that the enactment of the 1913 Utilities Act preempted whatever powers municipalities previously had to regulate public utilities so that no home rule powers to do so were in the contemplation of section 6(a) of the Illinois Constitution upon its adoption in 1970. While admittedly decided when Dillon’s Rule, not the broad grant of home rule powers of section 6(a) erected in 1970, was the law, the supreme court’s observations are, we believe, no less apposite today:
“[WJherever the Public Utilities act has granted a specific right or power which may conflict with a like right or power enumerated among those of cities and villages the former will prevail as a repeal, by implication, of such rights vested in the municipality. ***
Examination of the decisions of this court prior to the decision in the first Geneseo case discloses *** that the superior jurisdiction of the Commerce Commission was based upon an express authorization contained in the Public Utilities act, which was in opposition to a previous right existing in the municipality. ***
*** The power granted the Commerce Commission by sections 49, 52, 53, 5J+, 57, and 58 is direct, special and necessarily exclusive. The grant of power in these sections is: ‘The Commission shall determine and prescribe;’. ‘The commission shall have power;’ ‘the commission shall have authority to prescribe,’ and words of similar import, vesting specific authority to do the several things enumerated therein.
In each of the above cases the court held there was a specific grant of authority to the Commerce Commission giving it jurisdiction over something which before that time had been within the jurisdiction of a city or village. There was no doubt about a conflict of authority. The provisions of the statutes were in direct opposition to each other, and under the well-settled principles of statutory construction the powers granted the Commerce Commission became the dominant ones without a specific repeal of the conflicting statutory powers granted cities and villages. There was no question in those cases of inferring a grant of power in the commission, and no question but that there was a direct conflict in which one or the other was superior. The legal proposition to .be adduced from these decisions, and which has become stare decisis, is that wherever there is a specific power or authority granted to the Commerce Commission, which is in opposition to a like or *709 similar power granted the city or village the former will prevail, and the latter, without express repeal, will become ineffective.” (Emphasis added.) City of Geneseo, 378 Ill. at 514-17.
Section 54 of the Utilities Act specifically grants to the ICC authority to regulate gas meters. In so doing, it implicitly divests municipalities of that authority inasmuch as the power granted under that section is “direct, special and necessarily exclusive.” (City of Geneseo, 378 Ill. at 516.) Having been divested of that authority, we do not believe municipalities were revested therewith upon the adoption of the Constitution of 1970. Moreover, it is irrelevant that, as plaintiff notes, the city retains authority to regulate all other weights and measures under its charter and section 11 — 53—2 of the Illinois Municipal Code (Ill. Rev. Stat. 1981, ch. 24, par. 11 — 53—2). It is also irrelevant that the Weights and Measures Act (Ill. Rev. Stat. 1981, ch. 147, par. 101 et seq.), enacted in 1874 and reenacted in 1963, does not preempt or otherwise limit the city’s authority to regulate gas meters, the legislature having done so with the enactment of the Utilities Act in 1913. As such, we find inapposite City of Chicago v. Bartels (1909), 146 Ill. App. 180, and City of Chicago v. Waters (1936), 363 Ill. 125, 1 N.E.2d 396, aff’d sub nom. Hauge v. City of Chicago (1937), 299 U.S. 387, 81 L. Ed. 297, 57 S. Ct. 241, which upheld weights and measures ordinances of the city as not inconsistent with, nor repealed, superseded or modified by, the original Weights and Measures Act.
None of the “other considerations” plaintiff cites to distinguish Peoples Gas warrant a conclusion that the power to regulate gas meters is not exclusively reposed in the State by the Utilities Act.
Plaintiff notes that the city purported to regulate gas meters long before the ICC first promulgated General Order No. 159 in 1948 and that the city requires testing every seven years while the ICC requires testing only every 10 years and allows testing by scientific sample. We believe that, the city having been divested of the power at issue since 1913, it was not revested with it by the ICC’s nonexercise of its authority on the subject. Moreover, the wisdom of the ICC’s rules, in allowing testing by scientific sampling, is not for this court to decide.
Plaintiff also argues that the subject ordinance does not interfere with the ability of Peoples Gas to collect payment for its service and thus with the ICC’s rate-making authority, unlike the ordinance at issue in Peoples Gas. However, utility rate regulation by municipalities is not the only type of municipal regulation prohibited by the Utilities Act. Rather, “[t]he regulation of all aspects of utility *710business and service has long been held to be the exclusive province of the [ICC] [citations] and the exclusivity of the [ICG’s] jurisdiction has been repeatedly upheld [even] against the assertions of municipal authority over matters of health and welfare [citations].” Peoples Gas Light & Coke Co., 125 Ill. App. 3d at 101.
Plaintiff notes the court’s concern in Peoples Gas that “¡permitting every home rule unit *** to regulate in this field would subject utilities to multiple and sometimes conflicting governmental requirements which could only result in confusion and would seriously disrupt the [present] regulatory scheme.” (Peoples Gas, 125 Ill. App. 3d at 101.) She argues that concern is inapplicable here because Peoples Gas serves only the City of Chicago and thus cannot be subjected to multiple or conflicting requirements.
That Peoples Gas serves only the City of Chicago did not validate the subject ordinance in that case and does not validate the subject ordinance here. We read the quoted language from Peoples Gas as referring to the varying requirements to which all public utilities would be subjected by different municipalities empowered to regulate them, not the varying requirements to which one utility could be subjected by different municipalities. This is the more reasonable interpretation of this language, given that the Illinois legislature and courts “long ago recognized the overriding need for uniform, comprehensive utility regulation by vesting exclusive regulatory jurisdiction over this area in a single regulatory agency.” (Peoples Gas, 125 Ill. App. 3d at 101.) It is this need for comprehensive regulation of all utilities by the State which guides our decision, not the fact that Peoples Gas serves only the City of Chicago.
Plaintiff also asserts that the Peoples Gas court was apparently not advised that article 6 of the Utilities Act, comprised of sections 81 through 85, did provide for the exercise by municipalities of concurrent jurisdiction over local utilities. Parenthetically, she argues that the repeal of this article by Public Act 82 — 583, effective September 24, 1981 (1981 Ill. Laws 2942), was ineffective as a limitation of home rule powers for several reasons. Because we conclude that article 6 is unavailing to plaintiff, we need not address her arguments that its repeal was ineffective.
Article 6 of the 1921 version of the current Utilities Act provided for the concurrent exercise by municipalities of jurisdiction over public utilities. For a municipality to exercise such jurisdiction, however, section 85 required approval by referendum of the adoption of article 6 by a majority of the municipality’s voters. (Ill. Rev. Stat. 1921, ch. 1112/3, par. 89.) This requirement remained unchanged in *711the last version of section 85 preceding the repeal of article 6. (Ill. Rev. Stat., 1980 Supp., ch. 1112/3, par. 89.) Plaintiff did not allege below and does not allege here that the voters of Chicago ever approved the adoption of article 6 of the Utilities Act and, thus, that it is the source of the city’s authority to regulate gas meters. As such, that article is unavailing to plaintiff.
Plaintiff further cites Jones v. City of Chicago (1952), 348 Ill. App. 310, 108 N.E.2d 802, to contend that there is no conflict between the subject ordinance and the Utilities Act and that the ordinance controls. In Jones, the plaintiffs, operators of public passenger vehicles for hire, challenged a city ordinance requiring them to carry a minimum of $50,000 and a maximum of $100,000 in liability insurance. They contended that the ordinance contravened the Motor Vehicle Act (Ill. Rev. Stat. 1951, ch. 951/2, par. 1 et seq.), which required only $15,000 insurance for passenger carriers. After finding no conflict between the city ordinance and the Motor Vehicle Act and stating that the only difference between them was the amount of insurance required, the court stated: “An ordinance, because of local conditions, may impose more rigorous or definite regulations under a proper delegation of power in addition to those imposed by the State. Dean Milk Co. v. City of Chicago, 385 Ill. 565; and City of Chicago v. Union Ice Cream Co., 252 Ill. 311.” (Jones, 348 Ill. App. at 316.) We find Jones inapposite. It does not appear in Jones that the plaintiffs raised any question as to the city’s authority to regulate public passenger vehicles with respect to liability insurance after the Motor Vehicle Act purported to do so. That is, it does not appear that they challenged the exercise of home rule powers by the city after the State legislated in the same area. We recognize, however, that the question was raised in the Dean Milk and Union Ice Cream cases.
Dean Milk involved a challenge to a city ordinance requiring the use of “standard milk bottles” for the sale of milk in quantities less than one gallon. The plaintiffs contended that the Milk Pasteurization Plant Act of 1939 (Ill. Rev. Stat. 1939, ch. 561/2, pars. 115 through 119) had repealed, by implication, the city’s authority under the Cities and Villages Act (Ill. Rev. Stat. 1939, ch. 24, par. 1 et seq.) to regulate the sale of milk. The former act provided that “[sjingle service containers[ ] *** shall be manufactured and transported in a sanitary manner.” (Dean Milk Co. v. City of Chicago (1944), 385 Ill. 565, 575.) The plaintiffs, sellers of milk in single-service paper cartons, relied on this provision to argue that the Act thus permitted the use of such containers and divested the city of *712power to prohibit their use. The court concluded that the Act allowed the use of paper cartons in the State and set certain standards to which they had to conform but did not require municipalities to permit them within their boundaries. The court specifically relied on the Act’s saving clause, providing that nothing in the Act impaired or abridged the power of any city to regulate, inter alia, the sale of milk, to uphold the ordinance. 385 Ill. at 575-76.
In Union Ice Cream, Co., the plaintiffs contended that the Pure Pood Act repealed, by implication, the city’s authority under the Cities and Villages Act to regulate the sale of impure food by ordinance. After noting that the latter act had been reenacted after passage of the former, the court concluded that the Pure Food Act was not intended to deprive municipalities of their authority under the Cities and Villages Act to regulate the sale of food by ordinances not conflicting with the Pure Food Act. City of Chicago v. Union Ice Cream, Manufacturing Co. (1911), 252 Ill. 311, 313-14.
These cases do not require a conclusion contrary to that which we have reached in this case. In view of “the longstanding statewide interest in the field of public utility regulation *** manifested by the existence of the [ICC] and by the comprehensive and exclusive regulatory authority [it] has exercised for nearly 70 years” (Peoples Gas Light & Coke Co. (1984), 125 Ill. App. 3d at 100), we believe that City of Geneseo contains the principles applicable in determining whether the Utilities Act preempts any powers the city may have had prior to 1913 to regulate gas meters. “It is obvious that by *** enactment [of the Utilities Act] it was the legislative intent to withdraw from local municipalities supervision of public utilities and to vest the same in the commission with the exclusive power of regulation and control of all means and instrumentalities used by the utility in the conduct of its business.” (City of Geneseo v. Illinois Northern Utilities Co. (1936), 363 Ill. 89, 95, 1 N.E.2d 396.) As such, we find cases such as Jones, Dean Milk, and Union Ice Cream,, wherein the legislature passed laws on a subject without manifesting an intent to divest municipalities of their powers over the same subject, distinguishable.
Plaintiff lastly contends that Peoples Gas is contractually obligated to abide by the subject ordinance , by its acceptance of the franchises of the various gas companies previously operating in the city which it absorbed. She further contends that Peoples Gas has subjected itself to the ordinance by its practice, custom, and usage of abiding by a second ordinance stating that the city “may” inspect and test every gas meter to be installed in the city. Chicago Munici*713pal Code §187-14 (1983).
As already noted, under City of Geneseo II an express grant of specific authority to the ICC repeals, by implication, any grant of similar authority to a municipality. Moreover:
“It is irrelevant that a municipal franchise ordinance has been accepted and acted upon by the grantee utility, for such an ordinance cannot ‘stand in the way of the lawful exercise, by the [ICC], of the regulatory police powers conferred upon it by the General Assembly.’ [Citation.] Nor can a preexisting contract be considered a limitation on the exercise of the State’s police power.” (City of Peoria v. Peoria Water Co. (1977), 49 Ill. App. 3d 1066, 1068-69, 364 N.E.2d 1003.)
Finally, that defendant has voluntarily complied with other ordinances of the city cannot act as an estoppel against, or waiver of, its right to challenge the subject ordinance. Peoria Water Co., 49 Ill. App. 3d at 1069.
For all of the foregoing reasons, the order of the circuit court of Cook County dismissing plaintiff’s complaint is affirmed in its entirety.
Affirmed.
WHITE, P.J., concurs.
