OPINION OF THE COURT
Ciparick, J.In this appeal, we are called upon to determine whether the *123Legislature violated article V, § 1 of the New York State Constitution when it assigned and directed the State Comptroller to audit charter schools. We hold that the Legislature exceeded its constitutional authority by delegating and directing the Comptroller to conduct audits of charter schools. Therefore, the order of the Appellate Division should be reversed.
Background
In 1998, the Legislature enacted the New York Charter Schools Act (Act) thereby authorizing a system of charter schools to be created in New York State to provide “opportunities for teachers, parents, and community members to establish and maintain schools that operate independently of existing schools and school districts” (Mem in Support of 1998 NY Senate-Assembly Bill S7881, A11466, Bill Jacket, L 1998, ch 4). The Legislature found that creating a charter schools system would have no fiscal impact on the State because the “[flunds are provided for within [the] annual appropriation for school aid” (id).
Charter schools are “within the public school system” (Education Law § 2850 [2] [e]). Any child who is eligible for admission to a public school is qualified for admission to a charter school, and the charter school “shall enroll each eligible student who submits a timely application . . . unless the number of applications exceeds the capacity of the grade level or building” (Education Law § 2854 [2] [b]). A charter school cannot charge tuition or fees, except to the extent that fees are charged by other public schools, and shall be nonsectarian in its programs, admission policies and employment practices and is forbidden from engaging in any form of discrimination (see Education Law § 2854 [2] [a]).1 Further, the Legislature has stated that “[t]he powers granted to a charter school under [the Act] constitute the performance of essential public purposes and governmental purposes of this state” (Education Law § 2853 [1] [d]).
Under this Act, teachers, parents, school administrators, community residents or any combination thereof may submit an application to establish a charter school (see Education Law § 2851 *124[I]).2 A charter school application may be filed in conjunction with a college, university, museum, educational institution, or a not-for-profit corporation exempt from taxation under paragraph (3) of subsection (c) of section 501 of the Internal Revenue Code or for-profit business or corporate entity authorized to do business in New York (id.). A charter school application must be submitted to, and receive approval from, a “charter entity” (see Education Law § 2851 [3]). The Act defines a “charter entity” as (1) the State Board of Regents; (2) the Board of Trustees of the State University of New York; (3) the board of education of a school district that encompasses the geographical boundary in which the charter school will operate; or (4) if the charter school is to be located within the City of New York, the Chancellor of the City School District (id.).
Education Law § 2851 (2) states that the application must specify information, such as its mission statement, a description of an educational program and a description of student achievement goals that meet or exceed the student performance standards adopted by the Board of Regents for other public schools. Further, the application must provide a proposed budget and fiscal plan for the school, including supporting evidence that the fiscal plan is sound and that sufficient start-up funds will be available to the charter school (id.). Education Law § 2851 (2) also provides that the charter school application disclose its requirements and procedures for conducting at a minimum annual programmatic and independent fiscal audits, that are comparable in scope to audits of other public schools.
Once the application of the proposed charter school has been approved by the charter entity, the Act requires that the organizers of the proposed charter school and the charter entity enter into a proposed written agreement—the “charter.” The charter allows an applicant to organize and operate a charter school (see Education Law § 2852 [5]). Further, the charter must “include the specific commitments of the charter entity relating to its obligations to oversee and supervise the charter school” (id.). The Board of Regents, if not the charter entity, is required to give its final approval to all proposed charters before issuance (see Education Law § 2851 [3]; § 2852 [5], [5-a], [5-b]).
Once approved, the Board of Regents incorporates the charter school as an “education corporation” (see Education Law *125§ 216-a [1] [a];3 § 2853 [1]) governed by the Not-For-Profit Corporation Law (see Education Law § 216-a [4]) and its incorporation as an education corporation is “for a term not to exceed five years” (Education Law § 2853 [1] [a]). After the five-year term has expired, a charter school must apply for renewal of its charter by submitting a report detailing the progress of the charter school in achieving the educational objectives as set forth in its charter (Education Law § 2851 [4]). A charter school must provide a “detailed financial statement that discloses the cost of administration, instruction and other spending categories for the charter school that will allow a comparison of such costs to other schools, both public and private” (Education Law § 2851 [4] [b]), as well as copies of each of the annual reports of the charter school which include charter school report cards and certified financial statements (see Education Law § 2851 [4] [c]).
Indeed, a charter school has been deemed by the Legislature to be “an independent and autonomous public school” (Education Law § 2853 [1] [c])4 and that the charter entity and the Board of Regents are “the public agents authorized to supervise and oversee the charter school” (id.). Further, a charter school is governed by a self-selecting board of trustees that has “final authority for policy and operational decisions of the school” (Education Law § 2853 [1] [f]). However, it falls both to the Board of Regents and charter entity to oversee each school approved pursuant to the Act “and both may visit, examine into and inspect any charter school, including the records of such school, under its oversight” (Education Law § 2853 [2]). *126Further, “[ojversight by a charter entity and the board of regents shall be sufficient to ensure that the charter school is in compliance with all applicable laws, regulations and charter provisions” (id.).
The Act imposes additional layers of oversight designed to ensure the charter school meets its educational responsibilities by giving the school district in which the charter school is located the right to visit, examine and inspect the charter school for the purpose of ensuring that the school is in compliance with all applicable laws, regulations and charter provisions (see Education Law § 2853 [2-a]). Any evidence of noncompliance uncovered by the school district during its inspection of the charter school may be forwarded to the Board of Regents and the charter entity for action, which can include revocation of the school’s charter (see id.) see also Education Law § 2855).
In addition to being subject to inspection by the Board of Regents, the charter entity and the local school district, a charter school must submit an annual report to both the Board of Regents and to its charter entity. These reports include a charter school report card that outlines the measures of the comparative academic and fiscal performance of the school (see Education Law § 2857 [2] [a]). These
“measures shall include, but not be limited to, graduation rates, dropout rates, performance of students on standardized tests, college entry rates, total spending per pupil and administrative spending per pupil. Such measures shall be presented in a format that is easily comparable to similar public schools” (Education Law § 2857 [2] [a]).
A charter school’s annual report also must include “a certified financial statement setting forth . . . the revenues and expenditures for the preceding school year, including a copy of the most recent independent fiscal audit of the school” (Education Law § 2857 [2] [c]).
Charter schools are funded primarily with public monies.5 The Act requires that the “school district of residence shall pay directly to the charter school for each student enrolled in the charter school who resides in the school district the charter school basic tuition” (Education Law § 2856 [1] [a]). Further, a *127school district that has a charter school operating within its geographical area must “pay directly to the charter school any federal or state aid attributable to a student with a disability attending charter school in proportion to the level of services for such student with a disability that the charter school provides directly or indirectly” (Education Law § 2856 [1] [b]).
Should a school district fail to make the mandatory payments outlined in Education Law § 2856, the Comptroller must deduct from any state funds that become due to such school district an amount equal to the unpaid obligation to the charter school (see Education Law § 2856 [2]).6 Upon closure or dissolution of a charter school, its students and student records must be transferred to the school district wherein the charter school is located (see Education Law § 2851 [2] [t]), while its assets must be remitted back to the school district or to another charter school operating within the same school district (id.).
The Act, however, makes clear that a charter school does “not have the power to levy taxes or to acquire property by eminent domain” (Education Law § 2853 [1] [e]). The Act also makes it clear that no civil liability may attach to a charter entity, the Board of Regents, or to any of their members or employees, individually or collectively, for any acts or omissions of the charter school (see Education Law § 2853 [1] [g]). Also, it exempts the local school district, the charter entity and the State from liability for any debts or financial obligations of a charter school or any person and/or corporate entity that operates a charter school (id.).
The 2005 Legislation and This Lawsuit
In 2005, the Legislature adopted the school audit bill which directs the State Comptroller to audit all school districts, boards of cooperative educational services (BOCES) and charter schools operating within this state by March 31, 2010 (see L 2005, ch 267; see also Education Law § 2854 [1] [c]; General Municipal Law § 33 [2]). The Legislature determined that additional audits should be conducted by the State Comptroller because
“[sjchool districts, BOCES and charter schools are all public entities that use taxpayer funds. As such, the taxpayers who support these enterprises have a *128right to know that they are managed effectively and that proper measures are in place to protect against fraud and waste. The recent school district financial scandals and the failure of the independent auditor in those districts have made it clear that these additional safeguards are not merely appropriate; they are a good investment that will protect State and local taxpayers from financial practices that do not meet State standards” (Budget Report on Bills, Bill Jacket, L 2005, ch 267, at 5).
As amended, Education Law § 2854 (1) (c) requires that charter schools be subject to the State Comptroller’s audit just like other public schools. The Legislature also amended General Municipal Law § 33 to require that the Comptroller “cause the accounts of every school district, BOCES and charter school in the state to be examined” no later than March 31, 2010 (General Municipal Law § 33 [2]).
As a result of the 2005 amendments, respondents, by letter dated July 1, 2007, notified 31 charter schools located in New York City that the Office of the State Comptroller had scheduled a performance audit of charter schools authorized by the New York City Department of Education. The State Comptroller cited General Municipal Law § 33 as his authority to conduct the performance audits of the charter schools pursuant to article Y § 1 of the New York State Constitution. The audits were to include an assessment as to the extent that New York City charter schools met quantitative academic achievement goals and complied with student selection procedures and criteria, as set forth in their charters.
Upon receiving notice of the State Comptroller’s intent to audit them, several charter schools, by letter dated August 3, 2007, questioned whether the Comptroller had the authority to conduct academic performance audits. The Comptroller responded by letter dated September 27, 2007, reiterating that his authority derived from the 2005 amendments to General Municipal Law § 33, and that this Court’s decision in Matter of McCall v Barrios-Paoli (93 NY2d 99 [1999]) had clarified that the State Comptroller’s audit authority includes the power to conduct both financial and performance audits. The Comptroller concluded that the audits were proper because the matters to be examined “have clear fiscal implications for the public as well as the governmental entities that *129fund the charter schools and have programmatic and oversight responsibilities with respect to them” (Letter from Office of State Comptroller, Sept. 27, 2007, record at 254).
In December 2007, petitioners7 commenced this combined CPLR article 78 proceeding and an action for declaratory and injunctive relief against respondents Thomas E DiNapoli, as Comptroller of the State of New York, the Office of the State Comptroller and the State of New York. In particular, petitioners seek a declaratory judgment that the Comptroller lacks the authority to conduct audits of charter schools because article V, § 1 of the New York State Constitution prohibits the Legislature from assigning to the Comptroller the power or duty of auditing charter schools since they are not political subdivisions of the State, nor is the task of auditing charter schools an administrative duty incidental to the Comptroller’s constitutionally prescribed functions. Further, petitioners seek a judgment declaring that the grant of the Comptroller’s audit authority over charter schools contained in General Municipal Law § 33 (2) and Education Law § 2854 (1) (c) is unconstitutional and seek a permanent injunction prohibiting the Comptroller from conducting audits of charter schools. Respondents answered and moved for summary judgment.
Supreme Court denied respondents’ motion for summary judgment, holding that insofar as General Municipal Law § 33 (2) and Education Law § 2854 (1) (c) authorize or direct the Comptroller to audit charter schools, they violate article V, § 1 of the New York State Constitution (20 Misc 3d 235 [2008]). *130The court permanently enjoined the Comptroller from conducting any further charter audits.8
A divided Appellate Division reversed, holding that the Legislature did not violate NY Constitution, article Y § 1 when it directed audits of charter schools by the Comptroller (60 AD3d 119 [2009]). The majority found that given the Legislature’s broad delegatory authority regarding the Comptroller’s authority and the significant public funding involved, the Comptroller’s fundamental duty to supervise state fiscal matters was implicated. Therefore, the task of auditing charter schools was an administrative duty incidental to the Comptroller’s constitutionally prescribed functions. Petitioners appeal as of right, pursuant to CPLR 5601 (b) (1), and we now reverse.
Analysis
It is well settled that “[Legislative enactments enjoy a strong presumption of constitutionality” (LaValle v Hayden, 98 NY2d 155, 161 [2002]). A party contesting the constitutionality of a statute must overcome a very heavy initial burden by proving that the invalidity of the law is beyond a reasonable doubt (see People v Tichenor, 89 NY2d 769, 773 [1997], citing People v Pagnotta, 25 NY2d 333, 337 [1969])- Here, petitioners assert that the Legislature violated article Y § 1 of the New York State Constitution which provides in pertinent part that
“[t]he comptroller shall be required: (1) to audit all vouchers before payment and all official accounts; (2) to audit the accrual and collection of all revenues and receipts; and (3) to prescribe such methods of accounting as are necessary for the performance of the foregoing duties. The payment of any money , of the state, or of any money under its control, or the refund of any money paid to the state, except upon audit by the comptroller, shall be void ... In such respect the legislature shall define the powers and duties and may also assign to him or her: . . . supervision of the accounts of any political subdivision of the state . . . The legislature shall assign to him or her no administrative duties, excepting such as may be incidental to the performance of these *131functions, any other provision of this constitution to the contrary notwithstanding.”
Petitioners contend that assignment to the Comptroller of the power and duty to audit charter schools violates the constitutional provision because charter schools are not political subdivisions of the State, nor is the task of auditing charter schools an administrative duty that is incidental to the Comptroller’s constitutionally prescribed functions. We agree.
Although vigorously contested below, respondents do not now press the argument that a charter school is a “political subdivision” of the State. They maintain, however, that the Legislature’s assignment to the Comptroller of the duty to audit charter schools is permitted by the broad authority conferred by article Y, § 1. They further contend that the Legislature’s assignment of auditing duties to the Comptroller is constitutional because charter schools have a significant fiscal impact on both the State and school districts and should fall under the Comptroller’s incidental power to audit school districts.
In 1925, the Legislature determined that a major restructuring of government departments and their responsibilities was necessary. Article Y, § 1 was adopted in order to establish parameters of the Comptroller’s duties. We noted this legislative history in Blue Cross & Blue Shield of Cent. N.Y. v McCall (89 NY2d 160 [1996]) as support for our determination that the Legislature did not have the constitutional authority to assign to the Comptroller the power to conduct audits of private health insurance companies.
There, we rejected the State Comptroller’s arguments, which had been based upon practical concerns and public policy. Here, as in Blue Cross, the policy concerns appear to be substantial. However, the legislative enactments of General Municipal Law § 33 (2) and Education Law § 2854 (1) (c), to the extent they grant the Comptroller the power to audit charter schools, violate article Y, § 1. Indeed, in Blue Cross, we observed that it was important that the Insurance Department had long since been established and empowered to conduct audits and examinations of the insurance business (see 89 NY2d at 168-169).
Here, the Legislature has designated the Board of Regents and the charter entities as the public agents authorized to supervise and oversee charter schools. Respondents’ proposed audits include an assessment as to the extent to which New York City charter schools meet quantitative academic *132achievement goals and comply with student selection procedures and criteria, as set forth in their charters. Audits of charter schools—not political subdivisions—cannot be construed as incidental to the audits of school districts. The “plainly expressed constitutional prohibition” of article V, § 1 simply does not support respondents’ expansive reading of the term “incidental” (Blue Cross, 89 NY2d at 170).
Indeed, “[a]rticle V, § 1 of the State Constitution is a wellspring of the Comptroller’s authority . . . [which] broadly empowers the Legislature to delegate to the Comptroller both supervision of the accounts of any political subdivision of the State and administrative duties incidental thereto” (Matter of McCall v Barrios-Paoli, 93 NY2d 99, 105 [1999]). However, we have noted that “the objective behind article V, § 1 was to protect the ‘independent character of the Comptroller’s audit function,’ a goal that was accomplished by prohibiting the Legislature from assigning to the Comptroller unrelated duties” (Matter of Worth Constr. Co., Inc. v Hevesi, 8 NY3d 548, 552 [2007], quoting Matter of McCall v Barrios-Paoli, 93 NY2d at 107) and is fulfilled by our holding today.
Respondents maintain that our decision in Barrios-Paoli supports their contention that school districts, as recipients of billions of dollars in annual state aid, some passed along to support charter schools, are subject to the Comptroller’s audit because the State’s interest in monies appropriated to these school districts does not cease upon the districts’ receipt of the funds. Respondents further contend that the authority to supervise the accounts of the State’s political subdivision—the school district—leaves ample room for a wider inquiry into the efficiency and effectiveness of the district’s expenditures of state funds for charter schools. In other words, respondents believe that the Comptroller has the authority to “follow the money.”
Respondents’ reliance on Barrios-Paoli, however, is misplaced. The question presented in Barrios-Paoli was whether the Comptroller had the authority to inquire into the management and operations of city agencies that are political subdivisions. In answering that question in the affirmative, we did not indicate that the State Comptroller, as the State’s chief fiscal officer, could therefore audit the management and operations of an entity—not a political subdivision—solely on the basis that it receives state funds and performs a governmental function.
*133Neither does the language of article V, § 1—“[t]he payment of any money of the state, or of any money under its control, or the refund of any money paid to the state, except upon audit by the comptroller, shall be void”—support the constitutionality of the Legislature’s delegation to the Comptroller of the duty to audit charter schools. Respondents argue that the Comptroller’s authority to audit all vouchers before payment and all accounts (“pre-audit”) includes, by implication, “post-audit” authority to confirm that funds have been correctly disbursed and have been used in conformity with the particular purpose or program. However, respondents’ argument that the Comptroller is constitutionally entitled to audit the performance of charter schools, and perhaps question the wisdom of how charter schools provide instruction, cannot be considered to be within an audit of the monies paid by a school district acting as a mere conduit by forwarding the funds necessary to pay a student’s tuition. The money paid by a school district to a charter school is no longer under the State’s control once the funds have been transferred.
This does not leave charter schools without fiscal oversight as the fiscal affairs of each charter school are indeed subject to oversight by the Board of Regents, its charter entity, the school’s board of trustees and the mandatory independent annual audit. Accountability to the public is thus secured. The ultimate check, of course, is that a school may lose its charter if it is not meeting educational standards, as charters are renewed every five years.
Conclusion
Petitioners have shown, beyond a reasonable doubt, that the Legislature’s delegation of auditing authority over charter schools to the Comptroller violates article Y, § 1 of the New York State Constitution. The provisions of General Municipal Law § 33 (2) and Education Law § 2854 (1) (c), to the extent that these provisions direct the Comptroller to conduct audits of charter schools, are thus declared unconstitutional and the declaratory and injunctive relief, as granted by Supreme Court, is proper.
Accordingly, the order of the Appellate Division should be reversed, with costs, and the order and judgment of Supreme Court should be reinstated.
. However, this section does allow for a “single-sex charter school or a charter school designed to provide expanded learning opportunities for students at-risk of academic failure” (id.).
. An existing private school is not eligible to convert to a charter school (see Education Law § 2852 [3]).
. Education Law § 216-a (1) (a) states the term
“ ‘education corporation’ . . . means a corporation (a) chartered or incorporated by the regents or otherwise formed under this chapter, or (b) formed by a special act of this state with its principal purpose an education purpose and which is a member of the university of the state of New York, or (c) formed under laws other than the statutes of this state which, if it were to be formed currently under the laws of this state, might be chartered by the regents, and which has been authorized to conduct its activities in this state by the regents or as an authorized foreign education corporation with the consent of the commissioner.”
. There are certain instances in Education Law § 2853 in which the Legislature has determined a charter school should be considered a private school such as: (1) the power to designate textbooks, to purchase textbooks, to loan textbooks and to purchase supplies; (2) the designation of school library materials; (3) the designation of software programs to be used in conjunction with its computers; (4) local zoning, land use regulation, and building code compliance; and (5) student transportation.
. Respondents assert that petitioners received the majority of their revenue, between 63% and 96%, from the New York City School District, with the average being approximately 82%.
. The Act also encourages “[p]rivate persons and organizations ... to provide funding and other assistance to the establishment or operation of charter schools” (Education Law § 2853 [4] [d]).
. The caption indicates that there are 15 charter school petitioners: The Opportunity Charter School, New Heights Academy Charter School, The Renaissance Charter School, International Leadership Charter School, Hellenic Classical Charter School, Harlem Children’s Zone Promise Academy Charter School, Harlem Children’s Zone Promise Academy II Charter School, John V Lindsay Wildcat Academy Charter School, Hyde Leadership Academy Charter School, New York Center for Autism Charter School, Brooklyn Charter School, Manhattan Charter School, South Bronx Charter School for International Cultures and the Arts, Community Roots Charter School and Ross Global Academy Charter School. However, respondents assert that there are 16 charter school petitioners because the list did not include the Future Leaders Institute Charter School. Petitioners also include two not-for-profit organizations, The New York Charter Schools Association, Inc., and The New York City Center for Charter School Excellence, Inc. The charter school petitioners are members of The Charter Schools Association, Inc.
. As an initial matter, Supreme Court also rejected respondents’ argument that charter schools lack the legal capacity to assert a constitutional challenge against the State, finding that petitioners have standing.
