RICHARD M. DALEY, Mayor of the City of Chicago, et al., Defendants-Appellants (George H. Ryan, Governor of the State of Illinois, Defendant)." ], "opinions": [ { "text": "JUSTICE GROMETER\ndelivered the opinion of the court:\nPlaintiffs, James \u201cPate\u201d Philip, Henry Hyde, and the Village of Bensenville, initiated an action in the circuit court of Du Page County against defendants, the City of Chicago and Richard M. Daley. The complaint sought, inter alia, a declaration that an attempt by defendants to acquire property in anticipation of the expansion of O\u2019Hare International Airport without first obtaining approval from the Illinois Department of Transportation (IDOT) was beyond the authority of the city. Plaintiffs also sought a preliminary injunction prohibiting defendants from proceeding with land acquisition, and the trial court granted this request. Defendants now appeal, and we affirm.\nBefore proceeding further, we must address two matters. First, defendants have filed what they term an \u201cEmergency Motion for Summary Reversal.\u201d We ordered the motion taken with the case. After the parties completed their briefing of this appeal, the supreme court delivered its decision in People ex rel. Birkett v. City of Chicago, 202 Ill. 2d 36 (2002) (Birkett), and it is upon this opinion that defendants base their motion. As we explain below, we find Birkett distinguishable. Thus, we deny defendants\u2019 motion. Second, we observe that, between them, the parties have combined to amass a total of 70 footnotes in their briefs. Supreme Court Rule 341(a) states, \u201cFootnotes, if any, shall be used sparingly.\u201d Official Reports Advance Sheet No. 21 (October 17, 2001), R. 341(a) (eff. October 1, 2001). The parties are advised to abide by this rule in the future.\nI. BACKGROUND\nOn June 11, 2002, Chicago announced a plan seeking to acquire 433 acres adjacent to O\u2019Hare for runway expansion. Chicago stated that it would acquire the property either through voluntary transactions with property owners or through the power of eminent domain. Within the area of Bensenville that Chicago wants to acquire he 533 homes and 55 businesses. The area also contains a police station and a fire station. The housing in this area is affordable for people of low and moderate income. Further, the acquisition would displace over 400 students and possibly cause an elementary school to close.\nChicago did not seek IDOT\u2019s approval before commencing its land-acquisition program. The central issue involved in this appeal is whether section 47 of the Illinois Aeronautics Act (Aeronautics Act) (620 ILCS 5/47 (West 2000)) requires a party seeking to acquire land for airport development to obtain a \u201ccertificate of approval\u201d prior to proceeding. Section 47 states, in part, that \u201c[i]t shall be unlawful for any municipality or other political subdivision *** to make any alteration or extension of an existing airport *** for which a certificate of approval has not been issued by [IDOT].\u201d 620 ILCS 5/47 (West 2000). IDOT has promulgated a regulation explaining this language. The regulation provides:\n\u201cThe phrase, \u2018alteration or extension\u2019, shall include any of the following:\na) Any material change in the length, width or direction of runways or landing strips;\nb) Construction or installation of any building or other structure on the airport property which would extend above an approach slope or a transition slope or turning zone;\nc) Planting or permitting to grow any growth or placement of any other obstacle on the airport property which would extend above an approach slope or a transition slope or turning zone.\u201d 92 Ill. Adm. Code \u00a7 14.640 (1998).\nThis regulation was enacted by IDOT in 1985.\nPlaintiffs moved for a preliminary injunction, and a hearing was held on the matter. James Bildilli, the chief engineer of the Bureau of Airport Engineering for IDOT\u2019s Division of Aeronautics, testified, and an affidavit of his was submitted as well. Bildilli addressed IDOT\u2019s interpretation of section 47 of the Aeronautics Act. He explained that IDOT interprets \u201cmake any alteration or extension\u201d (620 ILCS 5/47 (West 2000)) to mean \u201cconstruct and put into service.\u201d He further stated that it has been IDOT\u2019s practice to wait until after the Federal Aviation Administration (FAA) has completed its approval process before taking action. This practice, according to Bildilli, allows IDOT to avoid unnecessary, costly duplication of functions properly performed by the FAA. See 620 ILCS 5/25 (West 2000). Further, Bildilli testified that IDOT does not require certification prior to land acquisition, even where the land is to be used for a runway. He added that if Chicago had sought a certificate prior to land acquisition, IDOT would have considered the application premature.\nThe trial court granted plaintiffs\u2019 request for a preliminary injunction. The trial court first observed that it is uncontested that Chicago intends at some point \u201cto make\u201d an alteration or extension of O\u2019Hare; therefore, it must seek IDOT approval eventually. The court found that land acquisition is part of the process of \u201cmaking\u201d a runway. Thus, the court reasoned that, as part of the process of making a runway, certification is required prior to land acquisition. The court also found that deference to IDOT\u2019s interpretation was inappropriate because the term \u201cto make\u201d (620 ILCS 5/47 (West 2000)), read in light of other pertinent portions of the Aeronautics Act, is not ambiguous. Accordingly, the trial court enjoined Chicago from proceeding with land acquisition until it obtained approval from IDOT.\nII. ANALYSIS\nDefendants assert that the trial court should not have issued a preliminary injunction, arguing that the Aeronautics Act (620 ILCS 5/1 et seq. (West 2000)) does not require them to seek approval from IDOT prior to acquiring land and that, in the alternative, federal law preempts the permit process set forth in the Aeronautics Act (see 620 ILCS 5/47 (West 2000)). We disagree with both contentions. In reviewing the propriety of a preliminary injunction, we normally apply the abuse-of-discretion standard. People ex rel. Klaeren v. Village of Lisle, 202 Ill. 2d 164, 177 (2002). However, the issues involved in this appeal turn largely on the construction of various statutes; therefore, we will conduct de novo review. People v. Studio 20, Inc., 314 Ill. App. 3d 1000, 1004 (2000). Finally, as will become clear, our analysis differs somewhat from that of the trial court. It is well settled that we review the correctness of the result reached by the trial court, not its reasoning (Department of Mental Health & Developmental Disabilities v. Illinois Civil Service Comm\u2019n, 103 Ill. App. 3d 954, 957 (1982)), and may affirm on any basis apparent in the record (Witters v. Hicks, 335 Ill. App. 3d 435, 445 (2002)).\nA. The Illinois Aeronautics Act\nDefendants first contend that the Aeronautics Act does not require them to seek approval from IDOT before beginning its land-acquisition program. Defendants\u2019 reasoning is relatively straightforward. First, they note that both this court and the supreme court have held that section 47 of the Aeronautics Act is ambiguous regarding how significant an alteration or extension of an airport must be before certification is necessary. Birkett, 202 Ill. 2d at 47; People ex rel. Birkett v. City of Chicago, 329 Ill. App. 3d 477, 484 (2002). Second, they rely on the well-established principle that when a statute is ambiguous, courts generally defer to interpretations by an agency charged with administering the statute. Automatic Data Processing, Inc. v. Department of Revenue, 313 Ill. App. 3d 433, 444 (2000); Smith v. Town of Normal, 238 Ill. App. 3d 944, 949-50 (1992). Third, they note that IDOT interprets section 47 to require a certificate only for acts that impact on things such as runways and flight paths. See 92 Ill. Adm. Code \u00a7 14.640 (1998). Finally, they conclude that since land acquisition does not affect such things, section 47 certification is not required, which is precisely what Bildilli stated was IDOT\u2019s position.\nDefendants\u2019 reliance on IDOT\u2019s interpretation of section 47 is misplaced. When a statute is ambiguous, an interpretation by an agency charged with administering it is generally entitled to significant deference. Illinois Consolidated Telephone Co. v. Illinois Commerce Comm\u2019n, 95 Ill. 2d 142, 152 (1983). However, when a statute is not ambiguous, it must be applied without resort to further aids of construction (Davis v. Toshiba Machine Co., America, 186 Ill. 2d 181, 184-85 (1999)), and there is no need to rely on an agency\u2019s interpretation of it (Boaden v. Department of Law Enforcement, 171 Ill. 2d 230, 239 (1996)). Furthermore, an erroneous interpretation is not binding on a court. Boaden, 171 Ill. 2d at 239. An agency may not expand or contract the scope of a statute under the guise of interpretation. Van\u2019s Material Co. v. Department of Revenue, 131 Ill. 2d 196, 203 (1989). In fact, our supreme court has stated that \u201c[rjeviewing courts may not rubber-stamp administrative decisions they deem inconsistent with the statutory mandate or that frustrate the policy underlying the statute.\u201d City of Freeport v. Illinois State Labor Relations Board, 135 Ill. 2d 499, 516 (1990), citing Bureau of Alcohol, Tobacco & Firearms v. Federal Labor Relations Authority, 464 U.S. 89, 78 L. Ed. 2d 195, 104 S. Ct. 439 (1983). Section 47 of the Aeronautics Act is not ambiguous regarding land acquisition for airport purposes. Accordingly, we have no occasion to defer to IDOT\u2019s interpretation of this statute, and, in any event, we would be bound to reject any interpretation that conflicts with its plain language.\nIn construing section 47, we begin with the fundamental maxims that the primary goal of statutory construction is to give effect to the intent of the legislature and that the best indicator of legislative intent is the plain language of the statute itself. Mobil Oil Corp. v. Industrial Comm\u2019n, 327 Ill. App. 3d 778, 790 (2002). Section 47 states, in pertinent part:\n\u201cOperation without certificate of approval unlawful; applications. An application for a certificate of approval of an airport or restricted landing area, or the alteration or extension thereof, shall set forth, among other things, the location of all railways, mains, pipes, conduits, wires, cables, poles and other facilities and structures of public service corporations or municipal or quasi-municipal corporations, located within the area proposed to be acquired or restricted, and the names of persons owning the same, to the extent that such information can be reasonably ascertained by the applicant.\nIt shall be unlawful for any municipality or other political subdivision, or officer or employee thereof, or for any person, to make any alteration or extension of an existing airport or restricted landing area, or to use or operate any airport or restricted landing area, for which a certificate of approval has not been issued by the Department; Provided, [sic] that no certificate of approval shall be required for an airport or restricted landing area which was in existence and approved by the Illinois Aeronautics Commission, whether or not being operated, on or before July 1, 1945.\u201d 620 ILCS 5/47 (West 2000).\nThe first paragraph quoted above sets forth certain requirements regarding what information must be included in an application for a certificate of approval. The second paragraph declares it unlawful to \u201cmake any alteration or extension\u201d of an airport without such a certificate.\nOur supreme court construed the phrase \u201cmake any alteration or extension\u201d in Birkett, 202 Ill. 2d at 46-48. The supreme court first observed that a strict construction of the phrase would lead to an absurd result. Birkett, 202 Ill. 2d at 47. Specifically, it would require a certificate for any alteration of an airport, including such things as the installation of new drinking fountains or the replacement of worn carpeting. Birkett, 202 Ill. 2d at 47. The court also acknowledged that the phrase clearly would include the construction of a new runway. Birkett, 202 Ill. 2d at 47. Birkett involved improvements to a terminal and ground transportation facilities. The difficulty, according to the supreme court, arises when one attempts to determine whether a project lying at some intermediate point in the continuum between runway construction and the installation of a drinking fountain requires certification. Birkett, 202 Ill. 2d at 47.\nThe court then noted that the legislature provided no guidance for resolving this question in the language of section 47. Birkett, 202 Ill. 2d at 47. Accordingly, it looked to IDOT\u2019s interpretation of the statute for guidance. Birkett, 202 Ill. 2d at 47. IDOT construes \u201calteration or extension\u201d to mean an improvement that \u201c(1) materially alters the length, width, or direction of a runway or landing strips; or (2) extends above an approach slope, transition slope, or turning zone.\u201d Birkett, 202 Ill. 2d at 48; see 92 Ill. Adm. Code \u00a7 14.640 (1998). The court found this interpretation reasonable. Birkett, 202 Ill. 2d at 48-49. Since the statute was ambiguous and IDOT\u2019s interpretation was reasonable, the supreme court deferred to IDOT\u2019s interpretation. Birkett, 202 Ill. 2d at 53-54. The plaintiffs did not contend that the improvements at issue in Birkett would materially alter a runway or obstruct a turning zone, approach slope, or transition slope. Birkett, 202 Ill. 2d at 54. Hence, the defendants were entitled to proceed with these projects without seeking a certificate of approval from IDOT. Birkett, 202 Ill. 2d at 55.\nThe instant case does not involve construction; it involves land acquisition. In Birkett, the supreme court noted that the legislature expressed no concern for an airport\u2019s ground transportation or terminal facilities in the Aeronautics Act. Birkett, 202 Ill. 2d at 50. Conversely, the legislature has explicitly addressed the subject of land acquisition relative to the certification process in section 47 itself. The first paragraph of section 47 states:\n\u201cAn application for a certificate of approval of an airport *** shall set forth, among other things, the location of all railways, mains, pipes, conduits, wires, cables, poles and other facilities and structures of public service corporations or municipal or quasi-municipal corporations, located within the area proposed to be acquired or restricted, and the names of persons owning the same, to the extent that such information can be reasonably ascertained by the applicant.\u201d (Emphasis added.) 620 ILCS 5/47 (West 2000).\nThat the statute specifies that an application must include certain information about the \u201carea proposed to be acquired\u201d is a clear indication that the legislature intended the certification process to precede land acquisition. Additionally, the application must include the names of the owners of the property sought to be acquired; therefore, the statute indicates that, regarding land acquisition, the legislature contemplated someone other than the proprietor of the airport owning the land at the time the application for a certificate was filed.\nIn short, the legislature addressed the subject of land acquisition relative to the certification process, and the plain language with which it spoke on this subject shows that it intended land acquisition to follow certification. Because the legislature has spoken plainly on this issue, Birkett is distinguishable. There is simply no need to consult IDOT\u2019s interpretation of section 47. It is for this reason we also find defendants\u2019 reliance on an opinion letter written by IDOT\u2019s secretary beside the point. Moreover, to the extent that IDOT\u2019s interpretation conflicts with the plain language of the statute, it must be rejected. Cella v. Sanitary District Employees\u2019 & Trustees\u2019 Annuity & Benefit Fund, 266 Ill. App. 3d 558, 564 (1994) (\u201cEven in light of [the] deference [normally accorded an agency], however, a court still has the authority to independently construe a statute and it will not adopt an agency\u2019s interpretation if it is inconsistent with the language of the statutory provision\u201d).\nDefendants raise two main arguments as to why this conclusion should not follow. First, they point out. that a statute must be interpreted as a whole and that a court must consider the purpose of the statute. Petroline Co. v. Advanced Environmental Contractors, Inc., 305 Ill. App. 3d 234, 237 (1999). They argue that, considered as a whole, interpreting the statute as requiring certification prior to land acquisition is inconsistent with the purposes of the Aeronautics Act. Second, they assert that the legislature has acquiesced in IDOT\u2019s interpretation of section 47.\nIt is true that the Aeronautics Act is primarily concerned with \u201cmaintaining a safe, uniform, and coherent system of flight patterns and air traffic.\u201d Birkett, 202 Ill. 2d at 50. However, it does not follow that air traffic and safety were the sole concerns of the legislature. Several other sections of the Aeronautics Act reveal that additional considerations are involved. First, we note that section 25 acknowledges a general concern for the \u201crights of others.\u201d 620 ILCS 5/25 (West 2000). More specifically, section 31 states that IDOT may create or modify a state airport plan with due regard for, inter alia, \u201cthe avoidance of unnecessary or unreasonable interference or conflict *** with existing important or essential facilities, or buildings devoted to the public use.\u201d 620 ILCS 5/31 (West 2000). Further, section 47 itself lists \u201crailways, mains, pipes, conduits, wires, cables, poles and other facilities and structures of public service corporations or municipal or quasi-municipal corporations\u201d as things that must appear in an application. 620 ILCS 5/47 (West 2000). While we agree that the legislature was concerned primarily with matters of air transportation when it enacted the Aeronautics Act, the above-cited sections reveal that the legislature was also concerned with the effect of airport development on surrounding communities. As such, we cannot agree that our interpretation of section 47 is inconsistent with the purposes of the Aeronautics Act.\nDefendants also contend that the legislature has acquiesced in IDOT\u2019s interpretation of section 47. In Birkett, 202 Ill. 2d at 53, our supreme court held that the legislature had fully acquiesced in IDOT\u2019s construction of section 47. However, the issue confronting the court in Birkett was different from the one before us in this case, and the legislature\u2019s acquiescence in IDOT\u2019s interpretation relevant to the issue in Birkett has no bearing here. In other words, Birkett is distinguishable. In Birkett, the issue was whether certification is required for the construction of a terminal that does not affect runways or flight paths. In the instant case, the issue is land acquisition. On this subject, the legislature has spoken. That the legislature acquiesced in IDOT\u2019s interpretation of \u201calteration or extension\u201d says nothing about land acquisition. As explained above, the plain language of section 47 indicates that certification must occur before land is acquired.\nIDOT\u2019s interpretation limits the reach of section 47 regarding issues of airport construction and improvement to projects that affect flight paths or runways. See 92 Ill. Adm. Code \u00a7 14.640 (1998). This interpretation does not conflict with the statute insofar as matters of construction and improvement are concerned. However, if this interpretation were to be applied to land acquisition, it would conflict with portions of section 47. A court \u201cwill not adopt an agency\u2019s interpretation if it is inconsistent with the language of the statutory provision.\u201d Cella, 266 Ill. App. 3d at 564; see also Abrahamson v. Illinois Department of Professional Regulation, 153 Ill. 2d 76, 91 (1992) (\u201c \u2018Where the language of the act is certain and unambiguous the only legitimate function of the courts is to enforce the law as enacted by the legislature.\u2019 [Citation.]\u201d). Thus, IDOT\u2019s interpretation cannot be applied to land acquisition.\nIn sum, we hold that the plain language of section 47 requires certification prior to land acquisition. Neither the purpose of the statute nor the General Assembly\u2019s acquiescence in IDOT\u2019s construction of the statute requires a different result. Accordingly, we find no error in the trial court\u2019s decision to grant plaintiffs\u2019 request for a preliminary injunction.\nB. Preemption\nDefendants also contend that federal law preempts state regulation of the expansion of airport facilities. To resolve this issue, it is important to recognize precisely what it is that defendants are arguing. The challenge they make is to the certification process itself. At times, they point out specific substantive requirements of the Aeronautics Act that they find objectionable, such as section 48\u2019s directive that IDOT consider the effect of the proposed development on \u201cthe then current State airport plan\u201d (620 ILCS 5/48 (West 2000)). However, these provisions are not ripe for review. IDOT has not sought to curtail the expansion of O\u2019Hare based on such requirements. It has taken no action regarding Chicago\u2019s plan. We will not assume that, being aware of the dictates of federal law, IDOT will take any action that will conflict with federal law. See Gromer Supermarket, Inc. v. Pollution Control Board, 6 Ill. App. 3d 1036, 1044 (1972) (\u201cNo action by the Board has made the issue ripe for judicial determination. We do not know if the Board will act upon this subject matter or whether it will, after due hearing, adopt no regulation or even an amended regulation with which plaintiffs may be in full accord\u201d). The sole issue before us is whether the existence of a state certification process, irrespective of the substantive requirements of certification, is preempted by federal law.\nBefore continuing, we must address plaintiffs\u2019 contention that this issue is not properly before this court. Plaintiffs argue that defendants failed to raise this issue in the trial court in response to plaintiffs\u2019 motion for a preliminary injunction. However, as defendants point out, they did raise this issue, albeit briefly, in their memorandum opposing plaintiffs\u2019 motion. Accordingly, we will address this issue. We also note that this court recently addressed a similar issue and held that federal law does not preempt section 47. See Birkett, 329 Ill. App. 3d at 486-89. We adhere to that holding; however, in the instant case, an additional issue relevant to preemption has arisen.\nPlaintiffs argue that the tenth amendment precludes preemption of the certification requirement set forth in section 47. U.S. Const., amend. X. The tenth amendment states, \u201cThe powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.\u201d U.S. Const., amend. X. The Constitution recognizes that both the federal government and the states are sovereigns in their respective realms and that the federal government is one of limited, delegated powers. Gregory v. Ashcroft, 501 U.S. 452, 457, 115 L. Ed. 2d 410, 421, 111 S. Ct. 2395, 2399 (1991). To the extent that a power is delegated to Congress by the Constitution, Congress is free to legislate and, by virtue of the supremacy clause (U.S. Const., art. VI, cl. 2), displace state interests in a given area. Gregory, 501 U.S. at 460, 115 L. Ed. 2d at 423, 111 S. Ct. at 2400. In a sense, the tenth amendment \u201cstates but a truism that all is retained which has not been surrendered.\u201d United States v. Darby, 312 U.S. 100, 124, 85 L. Ed. 609, 622, 61 S. Ct. 451, 462 (1941). It \u201cconfirms that the power of the Federal Government is subject to limits that may, in a given instance, reserve power to the States.\u201d New York v. United States, 505 U.S. 144, 157, 120 L. Ed. 2d 120, 138, 112 S. Ct. 2408, 2418 (1992).\nThe United States Supreme Court has confronted tenth-amendment issues in two main contexts. First, it has considered whether the tenth amendment precludes the application of a law of general applicability to a state. See, e.g., Garcia v. San Antonio Metropolitan Transit Authority, 469 U.S. 528, 83 L. Ed. 2d 1016, 105 S. Ct. 1005 (1985). Second, it has addressed congressional attempts to commandeer \u201cthe legislative processes of the States by directly compelling them to enact and enforce a federal regulatory program.\u201d Hodel v. Virginia Surface Mining & Reclamation Ass\u2019n, 452 U.S. 264, 288, 69 L. Ed. 2d 1, 23-24, 101 S. Ct. 2352, 2366 (1981). The issue before us lies somewhere between these two lines of cases. At issue here is whether federal law preempts the requirement that a municipality of this state receive approval from an administrative agency of this state before commencing an improvement to an airport. We find both lines of cases relevant to our inquiry.\nTo resolve this issue, we must first consider both Chicago\u2019s status as a governmental body and the nature of the power it seeks to exercise. Regarding Chicago\u2019s status, we find the following passage instructive:\n\u201cIt is universally recognized that municipal corporations are creatures of the State and that, absent constitutional restraints (e.g., voting rights (Gomillion v. Lightfoot (1960), 364 U.S. 339, 5 L. Ed. 2d 110, 81 S. Ct. 125); \u2018home rule\u2019 (Ill. Const. 1970, art. VII, \u00a7 6)), they are subject to the will and discretion of the legislature. (See, e.g., Hunter v. City of Pittsburgh (1907), 207 U.S. 161, 177-80, 52 L. Ed. 151, 158-60, 28 S. Ct. 40, 46-47; City of Chicago v. M. & M. Hotel Co. (1910), 248 Ill. 264, 268-69.) It is also well settled that the legislature has the power to fix and control the territory and boundaries of municipal corporations. (See, e.g., Richter v. City of Mt. Carroll (1947), 398 Ill. 473, 477; Geweke v. Village of Niles (1938), 368 Ill. 463, 467, 117 A.L.R. 262; Coles v. County of Madison (1826), 1 Ill. 154, 160.) The legislature has provided various methods for altering municipal boundaries, including provisions for the disconnection of property. See generally Ill. Rev. Stat. 1985, ch. 24, par. 7 \u2014 1\u20141 et seq., par. 7 \u2014 3\u20141 et seq.\u201d Harris Trust & Savings Bank v. Village of Barrington Hills, 133 Ill. 2d 146, 153 (1989).\nThus, unless the state or federal constitution requires otherwise, Chicago\u2019s ability to acquire land for the purpose of expanding O\u2019Hare is subject to the \u201cwill and discretion\u201d of the General Assembly.\nChicago is a home rule municipality. Endsley v. City of Chicago, 319 Ill. App. 3d 1009, 1013 (2001). However, the ability to acquire land in another municipality for airport purposes is not a power it possesses by virtue of this status. See Harris Bank of Roselle v. Village of Mettawa, 243 Ill. App. 3d 103, 114-15 (1993) (\u201cAny municipal attempt to exercise extraterritorial power is always subject to the requirements that the ordinance (1) be passed pursuant to legislative authority, (2) constitute a valid exercise of the police power, and (3) bear a reasonable relation to the public health, safety and welfare\u201d); Village of Sauget v. Cohn, 241 Ill. App. 3d 640, 645 (1993) (holding that a home rule municipality does not have the authority to enforce its ordinances extraterritorially). Instead, this ability arises from a statutory grant of authority made by the General Assembly in the Illinois Municipal Code (see 65 ILCS 5/11\u2014102\u20141, 11\u2014102\u20144 (West 2000)). Because Chicago\u2019s ability to acquire land for O\u2019Hare extraterritorially arises solely from a statutory grant, it is subject to the discretion of the legislature, and the legislature may attach any conditions it deems appropriate to its exercise. The legislature has specified that these provisions of the Illinois Municipal Code are subject to the provisions of the Aeronautics Act (see 65 ILCS 5/11\u2014102\u201410 (West 2000)). As explained in the preceding section, one of the requirements set forth in the Aeronautics Act is that a municipality obtain IDOT\u2019s approval before beginning a program of land acquisition. 620 ILCS 5/47 (West 2000). Thus, in the instant case, we are confronted with a municipality exercising a statutory power that it would not have in the absence of a legislative grant and upon which the legislature has placed certain conditions.\nDefendants argue that federal law preempts the certification process itself. At its core, this contention amounts to a claim that the legislature must confer on Chicago the ability to acquire land, by condemnation or otherwise, in a neighboring municipality, so long as it relates to the construction or improvement of an airport. If such a principle were to be given effect, it would strike at the very heart of what it means to be a sovereign entity. See Gregory, 501 U.S. at 460, 115 L. Ed. 2d at 423, 111 S. Ct. at 2400 (\u201cThrough the structure of its government, and the character of those who exercise government authority, a State defines itself as a sovereign\u201d). The legislature implemented a scheme whereby various state entities are allocated certain powers. Not only would finding the certification process preempted alter this balance of power, it would amount to the federal government dictating how this state must structure its government and conduct its affairs. We do not believe Congress intended such a result in enacting any of the various federal statutes pertaining to aviation, and we further doubt that Congress has any authority to dictate to a state how it must structure its internal government\u2014 barring such things as a violation of the equal protection clause or a similar provision.\nPreemption is, of course, a matter of congressional intent. Pacific Gas & Electric Co. v. State Energy Resources Conservation & Development Comm\u2019n, 461 U.S. 190, 203-04, 75 L. Ed. 2d 752, 765, 103 S. Ct. 1713, 1722 (1983). Within the limits of its constitutional authority, Congress may preempt state authority. Pacific Gas & Electric Co., 461 U.S. at 203, 75 L. Ed. 2d at 765, 103 S. Ct. at 1722. In fact, the Supreme Court has previously addressed the issue of preemption regarding local attempts to regulate air traffic and found that such attempts were preempted. See City of Burbank v. Lockheed Air Terminal, Inc., 411 U.S. 624, 36 L. Ed. 2d 547, 93 S. Ct. 1854 (1973). In Burbank, a municipality tried to impose a curfew on the operation of jet aircraft between the hours of 11 p.m. and 7 a.m. in order to limit the effect of aircraft noise on the surrounding community. In holding this action preempted, the Supreme Court relied on the \u201cpervasive nature of the scheme of federal regulation of aircraft noise.\u201d Burbank, 411 U.S. at 633, 36 L. Ed. 2d at 554, 93 S. Ct. at 1859. The Court also noted that preemption cases are sui generis and depend on \u201cthe peculiarities *** of the federal regulatory scheme in question.\u201d Burbank, 411 U.S. at 638, 36 L. Ed. 2d at 556, 93 S. Ct. at 1862. Unlike in Burbank, we find nothing in the federal regulatory scheme indicative of an intent by Congress to interfere with the manner in which this state allocates power among its various political organs.\nWhere congressional action could alter the constitutional balance between federal and state power, it should not be lightly assumed that Congress intended such a result. Gregory, 501 U.S. at 460-61, 115 L. Ed. 2d at 423-24, 111 S. Ct. at 2400-01. A court must be certain that Congress intended to upset this balance. Gregory, 501 U.S. at 460-61, 115 L. Ed. 2d at 423-24, 111 S. Ct. at 2400-01. Thus, \u201c \u2018[i]f Congress intends to alter the \u201cusual constitutional balance between the States and the Federal Government,\u201d it must make its intention to do so \u201cunmistakably clear in the language of the statute.\u201d [Citations.]\u2019 \u201d Gregory, 501 U.S. at 460, 115 L. Ed. 2d at 424, 111 S. Ct. at 2401, quoting Will v. Michigan Department of State Police, 491 U.S. 58, 65, 105 L. Ed. 2d 45, 54, 109 S. Ct. 2304, 2309 (1989).\nMandating that a state alter the relationship of authority it has established between its municipalities and agencies would certainly \u201calter the constitutional balance between state and federal government.\u201d See Highland Farms Dairy, Inc. v. Agnew, 300 U.S. 608, 612, 81 L. Ed. 835, 840, 57 S. Ct. 549, 551 (1937) (\u201cHow power shall be distributed by a state among its governmental organs is commonly, if not always, a question for the state itself\u2019). In Gregory, the United States Supreme Court considered whether the Age Discrimination in Employment Act of 1967 (29 U.S.C. \u00a7\u00a7 621 through 634 (1994)) provided a remedy to judges who were required to retire at the age of 70 by the Missouri Constitution. The court observed:\n\u201cThe present case concerns a state constitutional provision through which the people of Missouri establish a qualification for those who sit as their judges. This provision goes beyond an area traditionally regulated by the States; it is a decision of the most fundamental sort for a sovereign entity. Through the structure of its government, and the character of those who exercise government authority, a State defines itself as a sovereign.\u201d Gregory, 501 U.S. at 460, 115 L. Ed. 2d at 423, 111 S. Ct. at 2400.\nFurthermore, the court recognized that \u201c[congressional interference with this decision of the people of Missouri, defining their constitutional officers, would upset the usual constitutional balance of federal and state powers.\u201d Gregory, 501 U.S. at 460, 115 L. Ed. 2d at 423, 111 S. Ct. at 2401. We see little difference between Congress interfering with the selection of state officers and Congress interfering with the way a state delegates authority among its various political subdivisions. Accordingly, we will not presume Congress intended such interference absent a plain statement to the contrary.\nWe are unaware of any such statement appearing in any of the statutes upon which defendants rely in support of their preemption argument. Defendants specifically rely on the Federal Aviation Act of 1958 (49 U.S.C. \u00a7 40101 et seq. (1994)), the Noise Control Act of 1972 (49 U.S.C. \u00a7 44715 (1994)), and the Airport and Airway Improvement Act of 1982 (49 U.S.C. \u00a7 47101 et seq. (1994)). The Seventh Circuit has expressly held that \u201c[n]either the Constitution nor the Federal Aviation Act, as amended by the Noise Control Act of 1972, determines how Illinois apportions its governmental powers.\u201d Bieneman v. City of Chicago, 864 F.2d 463, 471-72 (7th Cir. 1988). Moreover, we have located no such statement in the Airport and Airway Improvement Act, which deals primarily with matters of funding (see 49 U.S.C. \u00a7 47101 et seq. (1994)), and defendants call our attention to no such passage. Therefore, we cannot conclude that Congress intended to preempt the way our government is structured in Illinois. The certification process that defendants challenge is a part of that structure.\nWe further doubt that Congress has the power to preempt the certification process set forth in section 47 (620 ILCS 5/47 (West 2000)). As noted above, Chicago\u2019s ability to acquire land outside its territorial borders is not a home rule power (Harris Bank of Roselle, 243 Ill. App. 3d at 114-15); rather, it is a power conferred upon Chicago as the result of a legislative grant (65 ILCS 5/11\u2014102\u20141, 11\u2014102\u20144 (West 2000)). The General Assembly has made an exercise of this power subject to the provisions of the Aeronautics Act (65 ILCS 5/11\u2014 102\u201410 (West 2000)), which includes section 47. Construing federal law as preempting the certification process is akin to saying that the General Assembly is required to grant Chicago more power. Because the power to acquire land extraterritorially for airport purposes arises from a legislative grant, it is the equivalent of saying that the General Assembly is required to legislate. We do not believe that this was Congress\u2019s intent, as we explain above. We include this discussion merely to point out a serious flaw in defendants\u2019 position.\nCongress cannot, of course, compel a state to legislate. The Supreme Court has never \u201csanctioned explicitly a federal command *** to promulgate and enforce laws and regulations.\u201d Federal Energy Regulatory Comm\u2019n v. Mississippi, 456 U.S. 742, 761-62, 72 L. Ed. 2d 532, 548, 102 S. Ct. 2126, 2138-39 (1982). In New York, 505 U.S. 144, 120 L. Ed. 2d 120, 112 S. Ct. 2408, the Supreme Court confronted an attempt by Congress to compel states to regulate nuclear waste according to Congress\u2019s instructions or to take title to the waste. The Court found that this attempt exceeded Congress\u2019s power and infringed on the core of state sovereignty, reasoning that the choice provided to the states was no choice at all, for \u201c[n]o matter which path the State chooses, it must follow the direction of Congress.\u201d New York, 505 U.S. at 177, 120 L. Ed. 2d at 151, 112 S. Ct. at 2429. The Court went on to note that it knew of no other federal legislation that \u201coffers a state government no option other than that of implementing the legislation enacted by Congress.\u201d New York, 505 U.S. at 177, 120 L. Ed. 2d at 151, 112 S. Ct. at 2429.\nWe recognize that the instant case differs significantly from New York. In New York, Congress had enacted a statute directing states to take certain actions. Here, the statutes upon which defendants rely contain no such provisions; rather, they are laws of general applicability. However, the underlying principles of New York provide some guidance. If we were to apply federal law in the manner advocated by defendants, we would be forced to say that the General Assembly is required to confer more power on Chicago than it has deemed proper. Federal law can no more compel the legislature to do so than it could compel New York to legislate according to federal standards or take title to nuclear waste. We see no significance in the fact that the compulsion would be indirect or unintentional in the present case. Congress cannot do accidentally what it could not do purposely.\nApplying federal law in the manner urged by defendants would leave this state with no choice but to confer upon Chicago the authority to acquire land outside of its territorial limits. It is true that Congress can seek to influence state action. For example, it may make the receipt of federal funds contingent upon certain conditions. See South Dakota v. Dole, 483 U.S. 203, 207-08, 97 L. Ed. 2d 171, 178-79, 107 S. Ct. 2793, 2796 (1987). Similarly, where Congress otherwise has the power to regulate an area, it can condition a state\u2019s continued regulation of that area on compliance with federal standards at the pain of federal preemption if the state does not comply. Hodel, 452 U.S. at 288-90, 69 L. Ed. 2d at 23-24, 101 S. Ct. at 2366-67. However, accepting defendants\u2019 argument, no such choice is available here. If we were to find the certification process itself preempted, we would be finding that the legislature had to confer this authority upon Chicago unconditionally.\nTo conclude, we hold that federal law does not preempt the certification requirement contained in section 47 (620 ILCS 5/47 (West 2000)). Congress intended no such result, and even if it did, preemption of the internal governmental processes of a state is generally beyond its power. In another case involving O\u2019Hare, the Seventh Circuit provided this apt summarization: \u201cIllinois might choose to exercise such powers as it has through the City Of Chicago, the \u2018owner\u2019 of O\u2019Hare. It might withdraw home rule from Chicago and exercise these powers through legislation of general application. Or it might exercise these powers through the courts.\u201d Bieneman, 864 F.2d at 471. In short, the way we do business in this state is our business, and ours alone. We expressly do not pass upon whether any of the substantive provisions of the Aeronautics Act are preempted by federal law. The sole issue before us is whether the certification process itself is valid in light of federal regulation of air traffic. We conclude that it is. See also City of Cleveland v. City of Brook Park, 893 F. Supp. 742 (N.D. Ohio 1995).\nIII.
