OPINION BY
Judge LEAVITT.
Before this Court, in our original jurisdiction, are preliminary objections of Governor Edward G. Rendell and the Philadelphia Parking Authority (Authority) to a complaint filed by the City of Philadelphia and the Mayor of Philadelphia, John F. Street (collectively, City), challenging a recent amendment to what is commonly called the Parking Authority Law, 53 Pa. [925]*925C.S. §§ 5501-5517.1 The core of the City’s challenge to this statutory amendment is that it interferes with the City’s home rule powers. It has already been determined by our Supreme Court that the Parking Authority Law is legislation extrinsic to the City’s home rule powers and, thus, its amendment to transfer control of the Authority from the City to the Governor did not infringe upon the City’s home rule powers. In this case, we consider whether another amendment to the Parking Authority Law, which extends the Authority’s administration of on-street parking in Philadelphia for ten years, requires a different conclusion.2 Deciding that it does not, we sustain the preliminary objections.
LEGISLATIVE BACKGROUND
1. The Parking Authority Law.
Although the legislative background of the Parking Authority Law has been aptly summarized in earlier cases,3 a brief historical review is material to understanding the issues in the present case. The General Assembly enacted the Parking Authority Law in 1947 in response to the growing demand for off-street parking in the urban areas of the Commonwealth following World War II, a phenomenon viewed as a statewide problem impacting those residing inside and outside the affected cities. The Parking Authority Law enabled cities, boroughs, and first class townships to create parking authorities in order to provide, administer, and collect revenue from various types of parking facilities.4 Any parking authority created under this enabling act is not considered a municipal instrumentality but, instead, constitutes a “public body corporate and politic, exercising public powers of the Commonwealth as an agency thereof.'” 53 Pa.C.S. § 5505. Among the benefits flowing from a parking authority’s designation as a state agency was the ability to finance construction projects free from the debt limits applicable to local governments5 and the right to engage in proprietary or business-type operations from which local governments might otherwise be precluded. See generally Southeastern Pennsylvania Transportation Authority v. Union Switch & Signal, Inc., 161 Pa.Cmwlth. 400, 637 A.2d 662, 664-65 (1994).
The Philadelphia Parking Authority (Authority) was created in 1950 by City ordi[926]*926nance adopted pursuant to the Parking Authority Law. Initially, the Authority only operated off-street parking garages. These operations continue to the present, and are carried out through leases with the City.6
The Parking Authority Law was amended in 1982 to allow cities to delegate certain on-street parking functions to parking authorities. Some of these functions, such as issuing parking tickets and collecting money from parking meters, are revenue-producing. This revenue is required to be distributed back to the municipality as provided by ordinance or resolution.7 Consistent with this amendment to the Parking Authority Law, the City, in 1988, enacted an ordinance' delegating to the Authority much of the City’s on-street parking services, which previously had been handled by multiple departments of the City.8 The City and the Authority executed an “Agreement of Cooperation” under which the Authority administers the City’s system of on-street parking.9 The net revenues collected by the Authority from on-street parking have been used by the City for its operations.
Throughout its existence, the Authority has issued numerous tax-exempt long-term bonds, some of which are outstanding, to finance parking-related development projects within the City and at the Airport. The City has served as guarantor on the bonds in the event of a default by the Authority. The City made this guarantee knowing that it would have revenue from the parking service contract; the bondholders were also made aware of this revenue stream, to the City. When the guarantee was made and the service contracts were executed, the City was in a position to control the' risks presented by these contractual relationships because, in effect, the City controlled the Authority. Until recently, the Authority’s five-member governing board was appointed by the Mayor. At issue in the present action are three amendments ■ to the Parking Authority Law, Act 22 and Acts 8 and 9, which changed the extent of the City’s control over the Authority.
2. Act 22.
The Act of June 19, 2001, P.L. 287, No.2001-22 (Act 22) was signed into law by then-Governor Thomas Ridge.10 Act 22 added a provision to the Parking Authority Law — applicable only to cities of the first [927]*927class — supplanting the mayor’s power to appoint the Authority’s governing board by placing that appointment authority in the governor.11 Act 22 also required the Authority to transfer up to $45 million of its retained earnings to the Philadelphia School District and to make similar subsequent annual transfers based upon the availability of earnings. 53 Pa.C.S. § 5508.1(q).12
The City filed a complaint in this Court’s original jurisdiction against then-Governor Mark Sehweiker seeking a declaration that Act 22 unconstitutionally infringed upon Philadelphia’s Home Rule Charter and violated certain “statutory pledges” that the City would retain control over the Authority until all bonds were fully met and discharged.13 Governor Sehweiker and the Authority filed preliminary objections in the nature of a demurrer to all counts of the City’s complaint. This Court sustained the preliminary objections, and the Pennsylvania Supreme Court affirmed. City of Philadelphia v. Schweiker, 817 A.2d 1217 (Pa.Cmwlth.2003), aff'd, 579 Pa. 591, 858 A.2d 75 (2004). While the Supreme Court appeal was pending, the City notified the Authority of its intent to terminate the Agreement of Cooperation as of March 31, 2004, and to reassume responsibility for all on-street parking functions.
2. Acts 8 and 9.
Following the City’s announcement that it intended to terminate the Agreement of Cooperation, the General Assembly passed two statutes further amending the Parking Authority Law. The first, the Act of February 9, 2004, P.L. 65, No.2004-8 (Act 8),14 required the City to continue to use the Authority to handle on-street parking and to transfer to the School District,' on an annual basis, the maximum portion of on-street parking revenues deemed available by the Authority’s Board. Act 8 made no provision for the expenses of the Authority, including the need to make interest payments to bondholders.
While Act 8 awaited the signature of the Governor, the General Assembly passed a second statute, the Act of February 10, 2004, P.L. 69, No.2004-9 (Act 9), which repealed the aforementioned provisions of Act 8 and extended the Agreement of Cooperation until March 31, 2014, effectively nullifying the termination notice given by the City to the Authority. Additionally, Act 9 provided for annual transfers of $25 [928]*928million of the net on-street parking revenues to the City, and transfer of the revenues in excess of $25 million to the School District. 53 Pa.C.S. § 5508.1.
ISSUES PRESENTED
The City initiated the present action on April 19, 2004, challenging the constitutionality of Acts 22 and 9.15 Specifically, in Count I of its petition, the City asserts that Act 22, as amended by Act 9, violates Pennsylvania law guaranteeing home rule to the City. In Count II, the City asserts that Act 22, as amended by Act 9, breaches certain “statutory pledges” contained in the Parking Authority Law. In Count III, the City asserts that Act 22 was enacted in violation of Article III of the Pennsylvania Constitution, which, inter alia, prohibits legislation from containing more than one subject. In Count IV, the City contends that Act 9 violates the City’s right to home rule. In Count V, the City asserts that Act 9 breaches another “statutory pledge” found in Section 10 of the Parking Authority Law. Counts VI and VII assert that Act 9 violates the requirements in Article III of the Pennsylvania Constitution that each bill be read three times in each house and that the original purpose not change. Finally, in Count VIII, the City argues that should this Court overturn Act 9 we should also find invalid those provisions of Act 8 repealed by Act 9.
In their preliminary objections,16 the Governor and the Authority assert that the City’s complaint fails to state a cause of action based upon alleged violations of: the Home Rule doctrine, “statutory pledges,” or the Pennsylvania Constitution. We consider the arguments and positions of the parties presented on each of these three legal questions.17
HOME RULE
On the issue of home rule, the City asserts in Counts I and IV of the [929]*929Complaint that Act 22, as implemented by Act 9, divests the City of control over on-street parking in Philadelphia18 and, therefore, violates the City’s Home Rule rights under the Pennsylvania Constitution, the First Class City Home Rule Act of 1949 (Home Rule Act),19 the Philadelphia Home Rule Charter,20 and ordinances of the Philadelphia City Council. Compl. ¶¶ 64, 77. We disagree.
Although the right to home rule is guaranteed by the Pennsylvania Constitution,21 that right is effected through enabling legislation such as the Home Rule Act, which identifies those powers that fall within the category of home rule powers and those that do not. Section 17 of the Home Rule Act grants to first class cities that adopt a home rule charter, i.e., Philadelphia, “complete powers of legislation and administration in relation to its municipal functions.” 53 P.S. § 13131. This grant of powers is made subject to limitations, restrictions and regulations enumerated in Section 18 of the Home Rule Act, 53 P.S. § 13133. See Schweiker, 579 Pa. at 605, 858 A.2d at 84. Stated otherwise, these limitations identify those activities that do not constitute home rale municipal functions. One such non-home rale municipal function is the undertaking of proprietary activities.
The City acknowledges that Section 18 prevents it from engaging in proprietary businesses, except as authorized in separate non-home rule legislation. However, the City argues that because Section 17 of the Home Rule Act grants the City power over all municipal functions, any function it delegates to an authority, such as parking, must be a municipal function. The argument is circular. It flows from a false premise, namely, that all the City’s powers flow from the Home Rule Act. In fact, the City’s authority to ran a parking business stems from the Parking Authority Law, not from the Home Rule Act. As explained in Schweiker, the Authority is not a department of the City. Rather, the Parking Authority Law, a non-home rule enactment, is the source of the Authority’s power, 53 Pa.C.S. § 5504(a), and the source of the City’s power, to delegate parking functions to the Authority, 53 Pa.C.S. § 5505(a).
The Authority is a Commonwealth agency, empowered to engage exclusively in commercial, i.e., proprietary functions; its “business” is generating revenue from parking cars on streets and in garages. Because Section 18 of the Home Rule Act, 53 P.S. § 13133, prohibits the city from engaging in proprietary activities, the Supreme Court rejected the City’s argument in Schweiker that exercising control over an authority that performs proprietary functions falls within the City’s home rule powers. The Supreme Court reasoned that even if the City’s appointment power fell “within the scope of the general home rule powers granted by the Home Rule Act when it was enacted, it does not follow that the Legislature could not remove such powers at a later date.” Schweiker, 579 [930]*930Pa. at 610, 858 A.2d at 87. - In other words, the General Assembly “retains express constitutional authority to limit the scope of any municipality’s home rule governance.” Id. The Court further explained that these limitations may be imposed by legislation extrinsic to the Home Rule Act, particularly where both statutes, i.e., the Home Rule Act and Act 22, pertain to first class cities. Finally, the Supreme Court held that “to the extent there is any conflict between these two enactments, Act 22 limits the City’s home rule rights in a manner that is consistent with Article IX, Section 2 of the Pennsylvania Constitution.” Id. at 612, 858 A.2d at 88. Accordingly, the Supreme Court held that this Court acted properly in sustaining preliminary objections to the City’s claims that Act 22 violated Philadelphia’s Home Rule Charter.
In its first supplemental brief ■ to this Court,22 the City concedes that the Schweiker decision precludes it from challenging, on home rule principles, the transfer from the mayor to the.governor of the power to appoint the Authority’s board members. The City also concedes that Schweiker clarifies that the City’s home rule powers do not extend to proprietary functions, such as off-street parking. Nevertheless, the City argues that Schweiker is not dispositive of its Act 9 challenges. Essentially, the City argues that managing on-street parking, unlike off-street parking, does implicate home rule powers. By extending the Agreement of Cooperation, Act 9 interferes with the City’s home rule power, an issue not addressed by the Supreme Court’s holding in Schweiker.
The threshold question in Schweiker was whether the appointment of members to the Authority’s board required the exercise of a home rule power. Schweiker, 579 Pa. at 606-07, 858 A.2d at 84-85. The Supreme Court held that it did not. The threshold question for this Court is very similar, ie., whether the responsibility to service on-street parking activities is a core municipal function that is governed exclusively by home rule. We think not.
The Parking Authority Law expressly authorized the Authority to engage in managing the revenue-producing project of on-street parking in Philadelphia. Since at least 1982, then, this part of on-street parking has been understood to be a proprietary function, as opposed to the kind of municipal function governed exclusively by the exercise of home rule powers. As the Supreme Court observed in Schweiker, it is “difficult to argue that exercising control over an authority which performs these [parking] functions is nonetheless included within such [home rule] powers.” Schweiker, 579 Pa. at 610, 858 A.2d at 87. Following this same logic, Schweiker requires us to conclude that the on-street parking duties assigned to the Authority are not municipal functions governed by home rule.
Act 9 did not negate the City’s control of a purely municipal function.23 [931]*931The on-street parking activities governed by the Parking Authority Law are proprietary activities that fall outside the reach of home rule power, as held in Schweiker,24 The Supreme Court determined in Schweiker that “Act 22 limits the City’s home rule rights in a manner that is consistent with the Pennsylvania Constitution.” Id. at 612, 858 A.2d at 88. Id. at 612, 858 A.2d at 88. Thus, the City’s Charter must give way where there is a conflict between it and amendments to the Parking Authority Law. This reasoning applies with equal force to the Act 9 amendments. Accordingly, we sustain the preliminary objections to Counts I and IV of the Petition.
STATUTORY PLEDGES
We turn next to Counts II and V of the City’s complaint, in which it asserts that Acts 22 and 9 violate certain “statutory pledges” in the Parking Authority Law. Specifically, the City argues that Act 22, as further implemented and confirmed by Act 9, breached “statutory pledges” in Sections 12 and 18 of the Parking Authority Law.25 The City also argues that Act 9 breached a [932]*932“statutory pledge” in Section 10 of the Parking Authority Law.26 The City strains in its argument that Schweiker, which specifically addressed the issue of “statutory pledges,” is not dispositive of the City’s present claims.
In Schweiker, the Supreme Court rejected the City’s theory that the legislature can make “pledges” that immunize a statute from any later amendments. With respect to the so-called “pledge” in Section 12 of the Parking Authority Law, the Court noted that “[wjhile this provision articulates a restriction on the Parking Authority’s powers as they existed under the prior version of the statute, it does not constitute a pledge on the part of the Legislature never to alter those powers in the future.” Schweiker, 579 Pa. at 614, 858 A.2d at 89 (citing In re Marshall, 363 Pa. 326, 337, 69 A.2d 619, 626 (1949) (“Legislative power is the power to make, alter, and repeal laws.”)).27 Further, the Supreme Court determined that the General Assembly’s constitutional authority to regulate home rule governance includes the ability to limit home rule powers by legislation extrinsic to the Home Rule Act. Amendments to the Parking Authority Law are examples of such limitations.
We find no merit in the City’s claim that “pledges” :in Sections 10, 12 and 13 of the Parking Authority Law are legally enforceable promises by the General Assembly never to alter the powers granted to the City in that statute. Such a pledge, if found, would itself violate one of the most basic principle of democratic rule, ie., that one legislative body may not bind a successor legislative body. Mitchell v. Chester Housing Authority, 389 Pa. 314, 321, 132 A.2d 873, 877 (1957). Accordingly, the preliminary objections to Counts II and V are sustained.28
CONSTITUTIONAL CHALLENGES
1. Single Subject.
The City asserts in Count III of its petition that Act 22 was unconstitutionally enacted as a bill containing more than a single subject, in violation of the “single subject” requirement of Article III, Section 3 of the Pennsylvania Constitution. The City raised this same issue in [933]*933Schweiker; however, the Supreme Court determined that the claim was abandoned on appeal. Notwithstanding the fact that no final decision on the merits of this issue was ever rendered, the City concedes in its first supplemental brief to this Court that Schweiker is dispositive of the “single subject” claim. Therefore, since the City has once again abandoned this issue, we sustain the preliminary objection to Count III.
2. Original Purpose.
In Count VI, the City asserts that the enactment of Act 9 violated Article III, Section 1 of the Pennsylvania Constitution,29 which bars the alteration of a bill to the extent it changes the bill’s original purpose. In support, the City notes that the original purposes of House Bill 1785 (Act 9) were: (1) to revise the residency requirement for members of parking authorities; (2) to clarify the voting rights of police officers; and (3) to authorize municipalities to remove fluoride from their public water supplies. Compl. ¶57. House Bill 1785 was considered for a third and final time and passed by both the House and Senate on February 9, 2004. On that day, the bill was amended to provide (1) that the Authority would continue to administer and enforce on-street parking regulations in the City, and (2) that net parking revenues would be directed to the District, thereby repealing sections of Senate Bill 279 (Act 8). The provisions related to police officers’ voting rights and fluoridation of public water were deleted. Compl. ¶ 58; H.B. 1785, 2003 Leg., Reg. Sess. (Pa.2004).
Our Supreme Court recently addressed the original purpose rule in Pennsylvanians Against Gambling Expansion Fund, Inc. v. Commonwealth, 583 Pa. 275, 877 A.2d 383 (2005), and announced a new two-prong inquiry for determining whether legislation violates the rule. First, a reviewing court must compare the final purpose of legislation to its original purpose and determine whether there has been an alteration or amendment of the original purpose. Id. at 317-18, 877 A.2d at 408-409. Second, a court must consider whether, in its final form, the title and contents of the bill are deceptive. Id. at 318, 877 A.2d at 409.
The linchpin of the first prong of the analysis is defining the original purpose of a bill. This has been explained by the Supreme Court as follows:
Regarding the determination of the original purpose of the legislation, we recognize the realities of the legislative process which can involve significant changes to legislation in the hopes of consensus, and the “expectation” that legislation will be transformed during the enactment process. Furthermore, our Court is loathe to substitute our judgment for that of the legislative branch under the pretense of determining whether an unconstitutional change in purpose of a piece of legislation has occurred during the course of its enactment. For these reasons, we believe that the original purpose must be viewed in reasonably broad terms. ... [I]t is helpful for a reviewing court to hypothesize, based upon the text of the statute, as to a reasonably broad original purpose. Given this approach of considering a reasonably broad original purpose, the General Assembly is given full opportunity to amend and even expand a [934]*934bill, and not run afoul of the constitutional prohibition on an alteration or amendment that changes its original purpose.
Id. (citations omitted) (emphasis added).
Applying the foregoing principles, we find that the original purpose of Act 9, viewed in reasonably broad terms, included the regulation of municipal parking authorities. As ultimately enacted, Act 9 provided that the Authority would continue to enforce and administer on-street parking in Philadelphia under the terms of the existing Agreement of Cooperation until 2014. The final version of Act 9 is still within its broad original purpose of the regulation of municipal parking authorities.30 We will not substitute our judgment for the General Assembly’s in this regard. The first prong of the inquiry is satisfied.
Turning to the second prong, we must determine whether, in its final form, the title and contents of the bill were deceptive. The final title of a bill is not deceptive if it “placed reasonable persons on notice of the subject of the bill.” Id.. at 818, 877 A.2d at 409. The final title for Act 9, Senate Bill 780, printer’s number 1186, states:
An Act amending Title 53 (Municipalities Generally) of the Pennsylvania Consolidated Statutes, codifying the . Municipal Authorities Act of 1945 and the Parking Authorities Law; revising provisions on purposes and powers of municipal authorities and residency requirements for municipal authority governing bodies; further providing for the organization and duties of governing bodies of parking authorities in cities of the first class; and making repeals.
S.B. 780, 2001 Leg., Reg. Sess. (Pa.2001). There is nothing deceptive about this title. It puts reasonable persons on notice that the legislature is amending the Parking Authority Law and changing “the organization and duties of parking authorities in first class cities,” i.e., Philadelphia.
Having found that Act 9 did not violate Article III, Section 1 of the Pennsylvania Constitution, we sustain the preliminary objection to Count YI.
3. Three Readings.
In Count VII of its complaint, the City asserts that Act 9 violates Article III, Section 4 of the Pennsylvania Constitution requiring that “[e]very bill shall be considered on three different days in each House.” Compl. ¶ 95. The City argues that, because of the last-minute changes described above, the form of House Bill 1785 (Act 9) considered and adopted was fundamentally different from the form of the bill introduced in the legislature.31 Because of these differences, the City contends that Act 9 was not considered on three separate occasions. Compl. ¶ 98. We disagree.
Article III, Section 4 does not require that each time a bill is amended, it must, again, be read three times. As this Court has explained:
[wjhen either the House or the Senate places amendments to legislation ema[935]*935nating in the other chamber, those amendments do not constitutionally require another separate three days of separate consideration.... [I]f it were otherwise and both chambers were constitutionally required to consider the conference amendments on three separate days, the entire legislative process would be bogged down to snail-paced process.
Fumo v. Pennsylvania Public Utility Commission, 719 A.2d 10, 15 (Pa.Cmwlth.1998). This case illustrates our point in Fumo. The record demonstrates, and the City admits, that House Bill 1785 (Act 9) was considered on three different days in the House and on three different days in the Senate.32 It, therefore, passes constitutional scrutiny even though the Senate amendments did not receive a separate three days of consideration in the House of Representatives.33 The preliminary objection to Count VII is sustained.34
CONCLUSION
In accordance with the above-referenced analysis, we sustain all preliminary objections and dismiss the Complaint.
ORDER
AND NOW, this 20th day of December, 2005, the preliminary objections in the above-captioned matter are hereby SUSTAINED and the complaint is DISMISSED.
